  • 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.

  • 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.

  • 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.

  • “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.

           Products
    • Authors: Jotarkar Parameshwar Sarangdhar, Narender Raju Panjagari
      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.

    • Authors: Vaghela Nileshkumar R., Subrota Hati, Kunal Gawai, Sreeja V.
      Abstract: Food borne diseases is the major concern along with malnutrition in developing countries and developed countries as well. Milk is rich source of nutrition with large number of pathogenic bacteria which are more susceptible to cause illness or death. Millions of people stuck with food borne outbreaks throughout the globe because of presence of pathogenic bacteria – disease causing microbiota like E. coli O157:H7, Salmonella, Shigella, Listeria, Campylobacter, S.aureus and Clostrida and their heat stable and heat labile toxins. The presence of food borne pathogens in milk and milk products is due to direct contact with contaminated sources in dairy farm environment and to excretion from infected udder of animal suffering from disease. Generally very few percentage (app. 1–2%) people of the globe consume raw milk and milk products while others use pasteurized one. But sometimes inadequate or faulty heat treatment and post processing contamination through infected supply chain may lead to major consequences related to outbreaks.Keywords: Food borne disease, milk and milk products, pathogens, contaminationCite this Article: Vaghela Nileshkumar R, Subrota Hati, Gawai K et al.

  • Development and Acceptability Evaluation of Soy Milk Obtained from Soy
    • Authors: Bharti Jain
      Abstract: Whole soybean is processed to make a rich, creamy milk-like liquid called soy milk. It has a unique delicious flavor. Soy milk makes a great substitute for milk, especially for individuals who cannot tolerate lactose (milk sugar). Soy milk is a good source of high-quality proteins, B-vitamins and iron. Soy milk is also a base for the preparation of many dairy analogs such as soy curd, soy tofu, etc. In the present study, soy milk was prepared from soy genotype JS 93-05 because of its high protein content. The main objective of the study was to find out the acceptability of soy milk and to compare the nutrient and cost of soy milk with cow’s milk. The processing of soybean is required to inactivate the anti-nutritional factors, to minimize the unacceptable beany flavor and improve the digestibility of the protein. About 8 L of soy milk can be obtained from 1 kg of dry soybean. To find out the acceptability of soy milk thirty young adult females of 35 to 40 years of age were selected. Acceptability of cow’s milk was 84.17%. Cow’s milk was compared with the acceptability of plain soy milk and flavored soy milk and the results reveled that acceptability of plain soy milk was 69.17% whereas acceptability of flavored soy milk was 83.33%. From these results it can be concluded that acceptability of flavored milk was equivalent to the cow’s milk. Plain soy milk was less acceptable due to its poor taste (33.33%). Results of nutrient content of soy milk revealed that there was not much difference in the protein and carbohydrate content of soy milk and milk. Major difference was observed in fat content of soy milk and this is due to the fact that higher yield of milk is obtained from 1 kg of soybean. Cost of soy milk (Rs. 8/kg) was less as compared to milk obtained from animal source (Rs. 20/kg).Keywords: Cow’s milk, soy milk, flavored soy milk, anti-nutritional factors, acceptability evaluation, soy genotypeCite this Article: Jain Bharti.

    • Authors: P. Narender Raju, Manoj Kumar C.T., Manoj Kumar C.T., Ashish Kumar Singh, Ashish Kumar Singh, Sangita Ganguly, Sangita Ganguly, Manav Manharbhai Patel, Manav Manharbhai Patel
      Abstract: In developing countries, depending upon the socio-economic situation, the nutritional status of the people is enhanced by encouraging increased use of inexpensive and available protein sources in child feeding. Traditional infant-feeding practiced in countries like India, is usually cereal based. Cereals in combination with milk solids are generally used for the preparation of weaning foods to improve the overall quality. Milk-cereal based complementary food is defined as food obtained from milk and milk solids, variety of cereals, pulses, soybean, millets, nuts and edible oil seeds and may contain other food additives and nutritionally significant minerals and vitamins. The quality of these food products during storage is affected by various factors such as inherent composition and exogenous factors such as packaging materials, head space air quality, storage temperature, humidity and handling. The published information about the milk-cereal based complementary foods along with the changes in the quality during storage has been briefly reviewed.Keywords: Milk-cereal based complementary food, protein sources, child feedingCite this Article:Narender Raju P, Manoj Kumar CT, Ashish Kumar Singh, et al.

  • Cow Milk and Human Health: A Review
    • Authors: Sanjiv Kumar, Kaushal Kumar, Sushma Suman, Pankaj Kumar
      Abstract: The milk of every species of mammal is unique and specifically tailored to the requirements of that animal. For example, cows' milk is three to four times richer in protein than human milk. It has five to seven times the mineral content. However, it is markedly deficient in essential fatty acids when compared to human mothers' milk. Mothers' milk has six to ten times as much of the essential fatty acids, especially linoleic acid (incidentally, skimmed cow's milk has no linoleic acid). It simply is not designed for humans. Except for domesticated animals to which we feed milk, humans are the only species that drinks the breast milk of another species, and the only species that continues to drink breast milk into adulthood. Today the top producers give ten times more milk. How was this accomplished? Drugs, antibiotics, hormones, forced feeding plans and specialized breeding; that's how.Keywords: Cow's milk, linoleic acid, lactose

  • Assessment of Heavy Metal Contamination in Dung Samples of Cattle during
           Monsoon Season in Vellore District, Tamil Nadu, India
    • Authors: A. Yasotha, T. Sivakumar, Thanga Tamil Vanan, K.N. Selvakumar, P.S.L. Sesh
      Abstract: A study was conducted to assess the sixteen dung samples from the dairy cattle reared around industrial areas of Vellore district during monsoon season. The collected samples were analysed for heavy metals using Inductively Coupled Plasma-Mass Spectroscopy (ICPMS). The result revealed concentration range of 2.580 to 20.030 ppm, 6.940 to 83.770, 1.310 to 19.270, 0.110 to 2.240 and below detectable level to 0.07 ppm for copper, zinc, chromium, lead and cadmium, respectively. A comparison of the mean distribution of the different metals studied shows that zinc had the highest mean distribution while cadmium had the least. The general trend of mean distribution of heavy metals showed Zn>Cr>Cu>Pb>Cd.Keywords: Cow, dung, heavy metals, inductively coupled plasma-mass spectroscopy

  • Demographic Profile of Dairy Farmers in the Industrial Areas of Vellore
           District –Tamil Nadu, India
    • Authors: Yasotha Appavu, T. Sivakumar, Thanga Tamil Vanan, K.N. Selvakumar, P.S.L. Sesh
      Abstract: The field survey was conducted to highlight the condition of dairying in industrial areas of Vellore districts, Tamil Nadu, India. A total of 32 farmers were selected randomly in two industrial areas of Vellore district, which covered around 270 dairy animals. Majority (71.88%) of the farmers had dairying as the primary occupation only (3%) farmers had agriculture as the primary occupation. Based on the land holdings 56.25, 37.50 and 6.25 per cent farmers were marginal, landless agricultural labourer and large, respectively. The average wet land holding was 1.18 acres and no farmers had dry land holding. The average herd size was 6.79 cross bred cows and 1.67 buffaloes. The red loamy soil (75%) was predominant in Vellore district. Literate farmers were 56.25 and 75 per cent of the farmers were income generator.Keywords: Dairy, farmer, dairying, occupation, status

  • Seminal Proteins as Markers for Bull Fertility
    • Authors: M. Karunakaran, T. G. Devanathan, Ajoy Mandal, Mohan Mondal, M. K. Ghosh, S. Garai, T.K. Dutta
      Abstract: Artificial insemination (AI) is the reproductive biotechnology that has made possible the safe use of semen from selected sires in a breeding female population. Application of AI as a tool for dissemination of semen from superior sires has contributed to the improvement of the genetic quality of breeding herds. This improvement has been exponential in dairy cattle, in which use of frozen semen is most common. Semen preservation and artificial insemination technique also used in conservation of wild and semi domesticated animals like mithun. A prerequisite for the best use of this genetic material is to obtain acceptable fertility after AI. For this reason, both screening of the semen for normality and fertility are essential. Accurate evaluation of the bull fertility is important because it influences the reproductive potential of the present and future herd. The aim of the breeding industry is to identify genetically superior bulls and maximize the number of offspring produced by these bulls. The fertility of the selected bull is important in achieving this aim.Keywords: Bull, semen, fertility, markers, proteins

  • Risk Factors Associated with Galactophagia and Its Impacts on Some
           Productive and Reproductive Traits in Dairy Cows and Buffaloes
    • Authors: ibrahim ahmed mostafa ahmed, Helal M. A., Ramadan S. G, Mahboub H. D., Byomi A. M., Reddy P. G.
      Abstract: The incidence of galactophagia (self and intersuckling vices in dairy animals) may lead to great loss in milk production, injuries and shape defect in teats as well as serious mastitis which reflect on general health condition of animals. Our field survey was carried out to spot the light on the relationship between galactophagia (self or intersucking), breed, housing system and parity on some productive, reproductive traits and udder health condition in dairy cows and buffaloes. The results revealed that, the average milk losses due to these vices reached to (33.42±0.51, 36.35±0.60 and 24.70±0.78 % of the total milk yield) for Holstein-Friesian, Baladi cow and Buffalo, respectively. Not only the amount of milk production decreased, but also the lactation period decreased significantly (P<0.01) while, days open and calving interval (CI) increased significantly (P<0.01). The incidence of self and intersucking could be a main cause of mastitis, which occurred more frequently in forequarters than hind quarters in suckled animals. In conclusion, self and intersucking considered as great economic problems in dairy cattle and buffaloes not only due to milk loss, but also other productive and reproductive traits in the herd and can cause serious mastitis.

  • Remodeling of High Yielding Dairy Holsteins Culling Strategies upon Their
           Prefresh Body Condition Score and Parity Number
    • Authors: Dawod A
      Abstract: The present study was conducted to detect the relationship between prefresh body condition score (BCS), lactation parity and their interactions to remodel the culling strategies and detect the best BCS for each lactation parity number which sustained high performance in high yielding dairy Holstein cows. A total of 1138 dairy records of private high producing Holstein Friesian farm (8000 kg milk/ season) were collected throughout the study. Dairy cows were grouped into three main categories according to their prefresh BCS, as low, medium, and over condition score cows for BCS values of 2–3, 3–4, and 4–5, respectively. Dairy cattle which were under the level of 2 point BCS were culled as a part of culling policy in these farms. Dairy cows were regrouped again according to their parity number into three groups 1st; 2nd, and 3rd for lactation parity of <3, 4–5, and >5, respectively. Both productive and some reproductive variables were used in this study such as milk yield (daily, 305 day yield, and total yield), milk curve (days to peak, initial milk yield, peak milk yield, and lactation persistency (LP)), and some reproductive variables (days to first estrus, and days open) were determined to indicate the best dairy cattle prefresh BCS per each lactation parity number sustained maximum dairy performance with little reproductive problems. The results of this study revealed that the medium condition score cows produced much milk as the same as over condition score cows. Moreover, young dairy cows of lactation parity <3 produced more milk than older ones. Old dairy cows with lactation parity >5 had high milk yield which is comparable with younger ones, if rigid culling programs was followed. Young dairy cows, which had lactation parity <3 needs no more than medium BCS value of 3–4 point to produce same milk as fatty ones. Old dairy cows need high BCS value of over 4 points during their prefresh phase to sustain high productive and reproductive performance. The culling programs in the high yielding Holstein dairy farms must be remodeled and directed to moderate (lactation parity 4–5) and old age (lactation parity >5) dairy cows which had poor body condition during their prefresh phase. Efficient body conditioning programs were followed, as these cows cannot produce or reproduce well. Old dairy cows must not be culled on the basis of their age alone, as these cows can produce as well as younger ones, if a firm culling policy was followed. Old dairy cows must not be culled from dairy herds if their economic values are still high, as the economic base must be put in front of all the bases.
