  • Ragi: A Powerhouse of Nutrients
    • Authors: Ishwar Patel, Komal Patel, Suneeta Pinto, Sunil Patel
      Abstract: Finger millet (Ragi, Eleusine coracana), is the principal food grain of the rural population in India, especially in South India.  It is very nutritious with respect to minerals, dietary fiber and essential amino acids. Amongst cereals, Ragi provides highest level of calcium including antioxidants and phytochemicals. The total dietary fiber of finger millet grain is relatively higher than that of most of other cereal grains which helps to control blood glucose levels in diabetic patients. It is usually converted into flour and a variety of preparations. Several methods of processing of ragi have been developed to make the final product more attractive in flavour, appearance, taste, and consistency.

  • Tagatose: A Low Calorie Multifunctional Sweetener
    • Authors: K V Mogha, A.R. Chaudhari, K.D. Aparnathi
      Abstract: A sugar called tagatose is one of the next things that will be appearing on the horizon for products labelled under the pseudo-hygienic appellations of “light”, “lite”, “low calorie”, “sugar free”, “sugarless”, “low fat”, “low sodium”, etc. The only true hygienic starting point, in this day and age of universal deceit, if we want good foods that are optimum for our health, is: “Start with fruit, grains, nuts, and vegetables simply and wholesomely prepared FROM SCRATCH at home”. This review contains a brief study on chemistry of tagatose, how it is produced, applications, limitations and legislations associated with tagatose.

  • Current and Future Prospects of Colostrum—Indian Ethnic Food
           Supplement
    • Authors: Rajamanickam K., Jayashree Gogoi, Leela V., Suganya G.
      Abstract: Traditional foods of India are called as ‘Functional Foods’ because they contain components such as body healing components, dietary fibres and growth promoters. Colostrum is the first secretion from mammary gland of an animal after parturition which contains high amount of many nutrients such as proteins, vitamins, minerals and biologically active substances like immunoglobulins, enzymes, hormones and growth factors. This physicochemical composition makes it highly useful food substance as nutraceuticals to promote growth and increase performance of athletes. Immunological and physiological considerations of bovine colostrum can be exploited more to explore their uses to its full potency and should be easy to use. Indigenous method of preparation of colostrum-based food products differs in various parts of India; accordingly the composition may also vary. Two main growth factors namely, TGFα and TGFβ and IGF1 and IGF2 has significant muscle and cartilage regeneration, so colostrum proves to be an ideal regenerative material for growth of body cells.

  • Influence of Genetic and Non-Genetic Factors on Lactation Traits in Dairy
           Cattle: A Review
    • Authors: Poonam Ratwan, Manoj Kumar, Ajoy Mandal
      Abstract: India has about 39.73 million crossbred cattle out of total 190.90 million (37.28%) cattle population as per the all India livestock census, 2012. The decade wise trend in livestock population (1997 to 2012) shows a distinctive swing in composition of dairy animal stock in favor of crossbred cattle, as their number increased by 20.18%, while that of indigenous cattle declined by 8.94% [1]. Selection of dairy animals is usually based on the lactation traits. All the lactation traits are affected by various genetic and non-genetic factors like sire, season of calving, period of calving, parity of animals, age group and genetic group of animals. Proper assessment or unbiased prediction of genetic worth (breeding value) depends upon the adjustment of significant effect of environmental or non-genetic factors on the lactation traits. The lactation traits reviewed were 305 days milk yield (305MY), total lactation milk yield (TMY), lactation length (LL), peak yield (PY) and milk production efficiency traits comprised of milk yield per day of lactation length (MY/LL) and milk yield per day of calving interval (MY/CI). In order to enhance the productivity, it is necessary to develop an understanding of the factors affecting lactation traits in dairy cattle.

  • Genetic Variability and Significance of STAT Gene in Dairy Animals
    • Authors: Manoj Kumar, Poonam Ratwan, Vikas Vohra
      Abstract: Signal transducer and activator of transcription (STAT) gene are a family of cytoplasmic proteins that are activated in response to a large number of cytokines, growth factors, and hormones. The interest in the bovine signal transducer and activator of transcription (STAT) gene has increased because STAT1 is involved in the development of the mammary gland and regulating the transcription of genes involved in milk protein synthesis and fat metabolism. STAT5 is related to milk composition, embryonic survival, conception rate, fertilization rate and calving interval of dairy animals. At present, seven bovine STAT genes have been identified and found that STAT1, STAT5A, and STAT5B were not exclusively regulated by individual effectors of differentiation, but their expression was tightly correlated with lipid accumulation. Studies on the expression of STAT in different tissues and at different developmental stages have shown that STAT1 and STAT3 are constitutively expressed at constant levels throughout pregnancy, lactation, and involution, whereas STAT4 and STAT5 are developmentally regulated. STAT5A is a candidate gene because it is a member of interferon and placental lactogen (PL) signal transduction pathways, which play important roles in reproduction and milk production traits. Some associated studies such as milk yield, fat content, protein yield, embryonic survival, conception rate and calving interval have been carried out in dairy animals. These associations will provide insight in to the underlying mechanism of STAT gene and polymorphisms that can be used for selection purposes in dairy animals.

  • Heterosis–Genetic Basis and Utilization for Improvement of Dairy
           Cattle: A Review
    • Authors: Manoj Kumar, Poonam Ratwan, Anil Kumar, Vikas Vohra
      Abstract: Heterosis is the phenomenon in which progeny of crosses between inbred lines or purebred populations are better than the expected average of the two populations or lines for a particular trait. Utilization of heterosis is the exclusive goal of crossbreeding. The amount of heterosis maintained in a herd depends on the type of crossbreeding system selected. Heterosis includes greater viability, faster growth rate and greater milk production in dairy cattle. The genetic basis of heterosis is nonadditive gene action (dominance, overdominance, pseudo-overdominance, and epistasis). The main requirements for heterosis are there must be genetic diversity between the breeds crossed and there must be some nonadditive gene effects present for the particular trait involved. No heterosis was observed for traits governed by additive gene action. However, it tends to be greatest for traits with low heritability and least for traits with high heritability. Traits of low heritability (reproductive traits) are generally most benefited from heterosis. They can be improved through the adequate use of crossbreeding systems.

  • Structured Lipids: A Unique Designer Lipid
    • Authors: Harini Venugopal, H.G. Ramachandra Rao, H. Arun Kumar
      Abstract: Structured lipids (SLs) generally refer to any fats that are modified or restructured from natural oils and fats or fatty acids primarily containing short or medium chain fatty acids and preferably essential fatty acids. The function and properties of structured lipids depend on the type of fatty acids moieties present and the position of their attachment to the backbone. Availability of SLs tightly relates to the new discoveries and collection of evidence in nutritional and functional studies. Production of SLs can be done by either chemical or enzymatic inter-esterification or synthesis depending on what products are needed. Randomized SLs can be produced by both methods. However, SLs with defined structures can only be produced by the enzymatic method with specific lipases. On the other hand, functions of SLs with respect to the consideration of medium chain fatty acids or PUFA have gained wide recognition. A number of products, largely with randomized structure, are available for different applications. SLs have potential applications in the delivery of energy and PUFA to persons suffering from malabsorption. Academic research has demonstrated a number of potential aspects from nutritional or biochemical points of view. With the potential perspectives in mind, technological development has already made the possibility of SL synthesis into production level with reasonably acceptable product standards.

  • Performance Evaluation of Barbari Goats in Semi-Arid Region of India: A
           Review
    • Authors: Ajoy Mandal, R. Behera, S. Rai, M. Karunakaran, T.K. Dutta
      Abstract: Barbari goat, a medium sized dual purpose goat breed in India, is known for its good lactation performance, high prolificacy, early maturity, low kidding interval, high kidding rate and better growth rate. The average weights of kids at birth, 3, 6, 9 and 12 month of age were 1.66±0.47, 5.88±0.41, 9.36±0.17, 12.85±0.25 and 16.08±0.35 kg, respectively. The average pre-weaning (0–3 months) daily weight gain was 59.9 g while post weaning (3–12 months) gain was 43.4 g. The feed conversion efficiency of this breed was 8.27±0.40% and is reported to vary from 6 to 10%. The average lactation milk yield at 90 and 140 days of lactation was 49.59±3.71 and 67.56±7.60 l, respectively with an average lactation length of 143.19 days. Regarding reproductive performance, the age of first mating and first kidding for this breed is reported as 12–14 and 17–19 months, respectively. The single, twin and triplet kidding varied from 50.6 to 59.0%, 32.3 to 39.8% and 5.59 to 10.67%, respectively. The average slaughter weight (kg), carcass weight (kg) and dressing (%) of adult animal of this breed was 25.57±1.73, 11.54±0.85 and 45.11±1.61 respectively. As the population of the breed in its home tract is declining over the years, so, there is a need for conservation of this breed. The central institute for research on goats (CIRG), Makhdoom, Uttar Pradesh, India has initiated to conserve this breed in its home tract.   Keywords: Barbari goat, growth performance, milk yield, carcass evaluation, IndiaCite this Article Ajoy Mandal, Behera R, Rai S et al.

  • Housing Patterns for Dairy Cattle in Nilgiri District of Tamil Nadu, India
    • Authors: T. Sivakumar, P. T. Suraj, A. Yasotha, Jayashree Phukon
      Abstract: A field work was conducted to assess the effect of climatic variables on dairy cattle under different housing patterns in Nilgiri, the Hilly zone of Tamil Nadu, India.  Initially a survey was conducted in this agroclimatic zone of Tamil Nadu with a prestructured interview schedule for identifying the present dairy cattle housing patterns, production and management measures. The annual compounded growth rates of T. maximum, T. minimum and temperature humidity index (THI) were worked out on the basis of the representative areas selected for the study. The result showed that the highest values for T. Max (Mean±SD) were recorded in metal sheet roofed shelter (22.13±1.66 ºC); whereas T. Min was reported in open housing (11.94±1.09 ºC). However, during cold season there was no significant difference (p<0.05) between the housing systems in temperature and THI at 8:00 am. The overall result of analysis of housing pattern in hilly zone indicated that the prevailing environmental condition in hilly zone is conducive for commercial dairy farming in all seasons.

  • Dairy Farming in a Selected Char Area of Northern Bangladesh: Prospect of
           Profitability and Contribution to Livelihood Improvement
    • Authors: J. U. Ahmed, S. K. Raha, M. H. Rahman
      Abstract: The study was conducted to assess the profitability of dairy farming in a char area of Northern Bangladesh and to evaluate the role of dairy farming to improve farmers’ livelihood. A total of 200 poorest households with dairying (100 treated and 100 controlled) and 200 with non-dairying were selected out of 520 households using simple random sampling technique. Majority of respondents in both the groups were males, aged between 36 and 50 years and had no primary education. Sixty five and 56 percent dairy households had 5 decimal homestead and 10 decimal cultivable land, respectively but 66 and 75 percent nondairy households had 10 decimal homestead and 20 decimal cultivable land, respectively. The status of homestead area and cultivable land of dairy farmers were better than the nondairy farmers. Significantly higher percentage of dairy household had access (P<0.05) to sanitation and drinking water facilities than the nondairy households. Average self-declared daily cash income of each dairy household was Taka 129±11.2. Profitability of dairy farming was measured in terms of gross return (GR), gross margin (GM), net return (NR), and benefit cost ratio (BCR) (undiscounted). Difference in differences (DID) approach was applied for analyzing the impact of dairy farming. Annual GRs from dairy farming was estimated at Tk. 18029 and Tk. 26003 before and after the project intervention, respectively. The estimated NR per cow per year stood at Tk. 537 and Tk. 6060 before and after intervention of the project, respectively. In the study area, BCR before the intervention of the project was 1.03 and 2.04 while it was 1.30 and 2.51 after the intervention on the basis of the full cost and cash cost, respectively. After the intervention of the project, there was a significant fall in the percentage of the farmers engaging with farming and day labourer whereas there was an increase in the percentage of the farmers engaging with only farming. On an average, family male members spent about 5 h a day on dairy cattle while the female members spent about 4 h a day over the study areas. Average total income had increased by 49% after the project intervention but it increased by only 17% in case of the controlled farmers. The highest (34%) treated group’s dairy income level was Tk. 10001.00–15000.00 followed by 33% and 18% of dairy income level of Tk. 15001.00–20000.00 and above Tk. 20000.00, respectively of respondent farmers. Income and expenditure of the treated group increased by 50% and 29%, respectively whereas it was increased by 18% and 8% in the case of control group. The length of time spent (working days) had increased by 100% in the study area. At last the sustainable livelihood framework including the asset pentagon was used to assess the impact of dairy farming on livelihood pattern.

  • Potentiality of Application of Microwave Heating in Dairy Industry
    • Authors: Sachin Lad, Pinto SV, Aparnathi KD
      Abstract: Microwave technology is an advanced technology that has been applied by the food industry in recent years. Microwave processes offer distinct advantages in conduction heating methods in food processing due to their potential for rapid and uniform product with reduced surface temperatures. Microwave radiation leads to lysis of microorganisms in foods resulting in increased shelf life of food products. When a food product is subjected to microwave heating, heat is generated inside the food rapidly when microwave penetrates through it therefore, a higher quality product is obtained in terms of taste, texture, and nutritional content. This review article discusses the mechanism of heating and destruction of microorganisms by microwave irradiation, its advantages and limitations, safety aspects and the application of microwave in dairy products and analysis of foods.

  • Significance of Growth Rate, Acceptability of Fermented Milk and Release
           of Peptides by Lactic Cultures
    • Authors: M. R. Kathiriya, J. B. Prajapati, S. Hati, Y. V. Vekariya
      Abstract: Ten lactic cultures (S. thermophilus MD2, S. thermophilus MD8, Lc. lactis 009, L. fermentum AI2, L. fermentum AI3, L. fermentum 138, L. plantarum AD29, L. rhamnosus NS4, L. rhamnosus NS6 and E. feacalis ND3) isolated from vegetables and fermented foods were evaluated for their potential to ferment milk, produce good quality curd and ability to release peptides in fermented milk. It was found that S. thermophilus MD8, S. thermophilus MD2 and L. rhamnosus NS6 were found to exhibit maximum growth rate (1.15, 0.98 and 0.49 respectively) and acid production rate (4.65, 5.14 and 5.59 respectively) in skimmed milk compared to other LAB. The curd/fermented milk prepared with S. thermophilus MD2, S. thermophilus MD8 and L. rhamnosus NS6  showed that the maximum acceptability as reflected by highest scores for overall acceptability i.e., 7.19, 7.07 and 7.04 respectively. Therefore, these three isolates were further studied for ACE (angiotensin-1 converting enzyme) inhibitory activity by spectrophotometric method and peptides released in milk medium after fermentation by RP-HPLC (reverse phase high performance liquid chromatography). L. rhamnosus NS6 exhibited relatively higher ACE inhibitory activity as well as released maximum peptides during RP-HPLC analysis than other two isolates. This reflects better acceptability and their application in preparation of acceptable quality fermented milk products.

  • Assessment of In Vitro Probiotic Potential of Lactic Acid Bacteria
    • Authors: Mital R. Kathiriya, S. Hati, J. B. Prajapati, Y. V. Vekariya
      Abstract: Probiotic potential of fermented milks isolates Lactobacillus rhamnosus NS6, Streptococcus thermophilus MD2 and Streptococcus thermophilus MD8 were carried out by performing various in vitro tests. MD2 and MD8 were able to survive at pH 2 and 3 in broth, while NS6 was found to be pH sensitive and could not survive at pH 2, but maintained its viability at
      3 pH. All the cultures were able to survive at 0.5 % (w/v) oxgall (bile) concentration in broth. NS6 was most resistant to bile than rest isolates. They were susceptible to ampicilin, azithromycin, tetracycline, gentamycin and erythromycin while these strains were resistant to nalidixic acid, oxacilin, colistin and kanamycin. Cell supernatant of NS6 showed a higher antimicrobial activity i.e., 24 mm zone against E. coli and S. aureus; 16 mm zone against
      B. cereus and S. typhi and neutralization of cell supernatant showed significant reduction in antimicrobial activity. All the three strains were hydrophobic to both, xylene and
      n-hexadecan. The mean percentage hydrophobicity was higher to xylene than n-hexadecanfor all the strains. Cell-auto-aggregation was found to be rising during 5 h of incubation for cultures. They were able to co-aggregate with B. cereus, S, typhi, E. coli and S. aureus (indicators). None of the culture could hydrolyze sodium taurocholate (bile) while they deconjugated sodium taurocholate to release free cholic acid. NS6 gave maximum bile deconjugation ability (364 µg/ml). Similarly, in case of cholesterol reduction and antioxidative activity (ABTS method), NS6 was more potent than others.

  • “High Melatonin Milk”- Milk with Intrinsic Health Benefit
    • Authors: Richa Singh, Priyanka Singh Rao
      Abstract: Melatonin C13H16N2O2 (molecular weight: 232) or N-acetyl-5-methoxytryptamine, is chemically an indoleamine and derived from the essential amino acid tryptophan. It is a hormone and due to secretion from pineal gland, it is also called as active pineal factor. Its IUPAC name is N-[2-(5-methoxy-1H-indol-3-yl)ethyl] acetamide. The indole ring acts as the chromophore showing maximum absorbance at 223 nm, and the functional groups contribute to its fluorescence property. Lerner et al. 1959 reported that extract from beef pineal gland are able to lighten frog’s skin by reversing the darkening effect of melanocyte stimulating hormone and therefore, named this compound as “melatonin” since it caused aggregation of melanin granules. Melatonin hormone is more effective and active when compared to other hormones like adrenaline and nor-adrenaline (100 times), triiodothyronine (200 times), and serotonin (5000 times) in preventing darkening of frog skin by contracting melanophores. It is a white powder having melting point of 117°C. It is an amphiphilic molecule (having solubility in both water and lipid) which facilitates its movement across the cell membrane and various body fluids and makes melatonin a prominent molecule in almost all tissues of mammals.

  • Emerging Pathogens in Dairy Industry
    • Authors: Mogha K.V., Chaudhari A. R., Subrota H.
      Abstract: The epidemiology of food borne disease is changing due to change in food habits of the consumers. New pathogens have emerged, and some have spread worldwide which includes Salmonella, Escherichia coli O157:H7, Campylobacter, and Yersinia enterocolitica. These pathogens have reservoirs in healthy food animals, from which they spread to an increasing variety of milk and milk products. If raw milk is consumed as such or if there is problem in steps of milk processing than it results in severe case of outbreaks of food borne illness due to consumption of contaminated milk and milk products made with it. This review mainly focuses on the emerging pathogens in dairy industry and rapid methods to detect them and control measures necessary to prevent this pathogens entering the milk processing area and thereby in milk products.

  • Use of Area Specific Mineral Mixture to Ameliorate Region Specific
           Reproductive Problems in Ruminants
    • Authors: M. K. Ghosh, M. Mondal, Rakesh Kumar Verma, Nirmala Muwel
      Abstract: Reproductive inefficiency in ruminant cows is one of the most important global problems affecting the profitability of the farm. Some trace minerals like Ca, P, Cu, Zn, Co and Mn have important roles to maximise reproductive performances. Even marginal deficiency of these minerals can impair reproduction showing clinical signs of deficiency. Effects of mineral deficiency and metabolic disorders in all categories of dairy animals have been observed due to lower mineral content and poor availability of essential macro and micro minerals from different feed stuffs. Deficiency associated problem have been observed in cattle of different regions and in most of the cases it differs from one region to another due to different soil composition, intensity of cropping, precipitation pattern and soil erosion pattern and so on. The assessment and preventives of mineral deficiency needs thorough understanding of the factors like age of animals, season, soil profile, plant materials and feeding practices. It is, therefore, important to understand the basics of mineral nutrition very clearly as also to meet the requirement of the animals to overcome the problem of deficiencies or excesses, so as to maintain productivity. The concept of area-specific mineral supplement is a new approach of low input and high output for the end users. In this review, the authors discussed the roles of some trace minerals on some productive and reproductive performance of ruminants with special emphasis on bovine species.

      Abstract: Edible films and coatings have long been used for food protection and shelf life improvement. Essential components for producing edible films and coatings are biopolymers, plasticizers and certain optional ingredients. Edible films and coatings have been used as vehicles for delivery of minerals such as calcium, zinc, iron and magnesium and also for delivery of vitamins such as niacin, riboflavin, vitamin A, vitamin E and vitamin C in food products such as vegetables, rice, etc. However, there are limited studies focused on dairy products. In the present review, the scope of such edible coatings for delivery of micronutrients is presented.

  • Mithun: A Promising Milch Animal of the Northeastern Hill Region of India
    • Authors: M Mondal, R K Singh, K K Baruah, A Kumar, V Singh
      Abstract: Mithun (Bos frontalis), a rare bovine of Southeast Asia, is the descendent of wild Indian gaur (Bos gaurus gaurus). This unique animal is found mainly in four different states of the North-Eastern Hills region of India viz., Arunachal Pradesh, Nagaland, Manipur and Mizoram, and also in some locations of Bhutan, Myanmar, Bangladesh and China. Though the mithun is mainly reared for meat, it has the potential for milk production. Mithun produces milk of high quality containing double the quantity of energy than cattle cow milk. In addition, mithun milk contains high quantity of lactoferrin; an antimicrobial element combats for pathogenic infection. Unfortunately, mithun has not yet been explored fully as a milch animal. Milk production potential of mithun can be enhanced significantly through using suitable scientific packages of practices and appropriate technological interventions.

  • Development of a New Kisspeptin Based Method of Ovulation Synchronization
           for Crossbred Dairy Heifers
    • Authors: M. Mondal, KK Baruah, M Karunakaran, MK Ghosh, TK Dutta
      Abstract: The aim of the present study was to develop a new method of synchronization of estrus/ovulation for crossbred cows based on kisspeptin, a potent secretagogue of GnRH. For the purpose, a total of 108 estrous cycles were studied in cyclic heifers. The animals divided equally in to two groups were treated either with ovsynch protocol of estrus synchronization (group-I; GnRH: day 0; PGF2α: day 7 and GnRH: day 9) or with a new method of synchronization based on kisspeptin (group-II; kisspeptin: day 0; PGF2α: day 7 and kisspeptin: day 9). Heifers were monitored regularly with transrectal ultrasonography for follicular dynamics and occurrence of ovulation. It was found that the kisspeptin based protocol induced better growth of follicles than ovsynch one. Ovulation rate was significantly higher (P<0.05) in the animals of group-II than group-I. As revealed through ultrasonography as well as plasma progesterone profiles, the process of luteolysis starts early even before PGF2α injection in kisspeptin based protocol than ovsynch. In conclusion, we developed a new method of synchronization of estrus/ovulation based on kisspeptin in bovine species for the first time. The newly developed method is found to be better than the conventional ovsynch method in terms of percent ovulation in the treated animals.

  • Carbon Footprints of Dairy Animals: Causes and Its Mitigation
    • Authors: Poonam Ratwan, Ajoy Mandal, Manoj Kumar, M Karunakaran, TK Dutta
      Abstract: Greenhouse gases are building up in the atmosphere to a larger degree leading to “global warming”. The total quantity of gaseous emissions of greenhouse gases emitted by an individual in one year; directly or indirectly is measured in terms of 'carbon footprint'. Livestock play an important role for emission of greenhouse gases through various ways like rumen fermentation, manure and fodder production, milk, beef production etc. The demand for livestock products is increasing regularly and livestock products carry a high carbon footprint as compared to other products. Thus, in order to balance environmental concerns with the emergent global demand for dairy products along with economic feasibility to individual dairy producers there is need of emissions mitigation strategies. Proper management practices can lead to reduction in carbon footprints of livestock which in turn will help to minimize the negative effects of emissions on climate change.

  • Wheat and Its Application in Dairy Products: A Review
    • Authors: Aparna S., Komal Patel, Sunil Patel, Suneeta Pinto
      Abstract: Wheat is one of the most important crop among the cereals by area planted; followed in importance by corn, barley and sorghum. It is the best of the cereal foods and provides more nourishment for humans than any other food source. Wheat is a major diet component which supplies about more than 60% of the total daily requirements of protein and calories for the world's population. It contains minerals, vitamins, fats (lipids) and is a good source of fibers making it a highly nutritious product. Cereals and milk are blended to compensate for deficiency of lysine. The proteins from wheat in combination with milk can make up the deficiency of protein quality. Incorporation of wheat as an ingredient in dairy products would help in alleviating its nutritional value. A number of products obtained from wheat with good nutritional value such as wheat germ, aleurone flour and wheat bran are available. Fortification of dairy product with these ingredients would help in the manufacture of neutraceuticals with improved nutritional and functional properties.

  • Influences of Prefresh and Early Fresh Body Condition Score Changes on
           Some Holstein Dairy Performance Traits
    • Authors: Dawod A., Abdel-Hamid T. M., Ramadan S.
      Abstract: This study was performed to investigate the effect of body condition change from the prefresh to early fresh periods on the subsequent milk production performance in Holstein dairy cows. For this purpose, 89 Holstein cows in a private high yielding dairy enterprise (average milk yield 8000 kg/season) were included in this study. Body condition score (BCS) was evaluated at the prefresh period (260–270 day) post last insemination, as well as one month postpartum. Evaluations of BCS were performed via, two evaluators on a scale of 1–5 points and the average BCS value for each cow was detected. BCS loss was estimated via, subtract of postpartum BCS value from the prefresh one. Data of the daily, initial, 305-day, and actual milk yield were collected and recorded. The results of this study revealed that, fatty cows during their prefresh phase (BCS 4.5–5.0 points) had high dairy performance, as these cows depicted the highest values of daily milk yield (37.58 kg), initial milk yield (43.38 kg), 305–day milk yield (11461.00 kg) and actual milk yield (12229.38 kg). Moreover, the cows with a postpartum BCS of 3.5–4.0 points recorded the highest significant daily milk yield (37.93 kg), 305-day milk yield (11566.67 kg), initial milk yield (49.00 kg) and actual milk yield (14945.00 kg). The cow losing from (–0.5)–(–1.0) point BCS has the highest significant daily and 305-day milk yield. In conclusion, BCS significantly influenced the milk performance traits of Holstein cows both at prefresh and postpartum period. For higher performance, the cows should be with somewhat heavy BCS at prefresh and with medium BCS postpartum. The dairy Holstein cows could loss about 0.5–0.75 BCS unit during their early fresh phase with efficient milk production. Further research is needed to prove this presumption.
