           of Erciş District of Van Province

    • Authors: Emre ALARSLAN; Turgut AYGÜN
      Abstract: Objective: This study was conducted to determine some morphological characteristics of domestic horses in Ulupamir village of Erciş district of Van province.Materials and Methods: For this aim, various body measurements of horses were taken to obtain data on morphological characteristics. Investigation was carried out on a total of 37 horses (71%), 20 stallions and 17 mares, belonging to 32 horse breeders (72%) in Ulupamir village.Results: The least-squares means of withers height (WH), body length (BL), rump height (RH), chest depth (CD), chest width (CW), chest circumference (CC), and shinbone circumference (SC) of horses were 133.97, 136.91, 133.56, 57.16, 34.91, 151.00 and 17.24 cm, respectively. The effect of age groups on rump height and shinbone circumference was statistically significant (P<0.05). Correlation coefficients between WH and BL, RH, CW, CC, and SC were statistically found significant (P<0.05; P<0.01).Conclusion: Since it has an important place in Kirgiz culture, horse breeding carries out their breeding activities depending on the breeding experiences they have gained in the historical process in village of Ulupamir. It is concluded that the horses raised at village were similar to East Anatolia horse breed for the morphological traits.

  • Current Situation of Sheep Breeds Raised in the Eastern Anatolia Region

    • Authors: Çağrı KANDEMİR; Turgay TAŞKIN
      Abstract: Objective: To determine the current status of sheep breeds in fourteen provinces in the Eastern Anatolia Region by taking into ac,count the yield, tail shape and origin.Method: The research material consists of the data obtained in 2021 through the Livestock Information System (HAYBIS) belonging to the Ministry of Agriculture and Forestry of the Republic of Turkey. The tables are based on the number of sheep owned by the provinces in the Eastern Anatolia Region according to the classification of statistical regional units. Sheep breeds; yield aspects (meat-milk-fur-fleece-lamb) and tail shapes (thin, fat, semi-fat). This grouping is based on the morphological and physiological characteristics determined in the Turkey Animal Genetic Resources Catalogue published by the Ministry.Results: The total number of sheep genotypes bred in the region is 131 and the number of sheep is 11.803.377 heads. While the province with the highest number of sheep breeds is Van (3.036.270 heads) with 25.72%, the province with the lowest number of sheep breeds is Ardahan (125.311 heads) with 1.06%. The province that raises the most domestic sheep breeds is Van (3.035.405 heads), respectively; It is followed by Ağrı (1.384.089 heads), Iğdır (1.227.944 heads), and Muş (1.056.823 heads). In the region, there are 4 cultural breeds of sheep and the number of domestic breeds is relatively higher. The difference between the provinces in terms of origin, tail shape, and yield is significant (p<0.05). In all provinces in the region, a single yield aspect (meat, milk, or fleece) has not been a prominent province. In these provinces, it is seen that sheep breeds with combined yield are bred more intensively. Another important result is that due to the climatic conditions in all provinces, it was determined that fat-tailed s

  • Relationship Between Meat Quality and Animal Nutrition

    • Authors: Sibel SOYCAN ÖNENÇ; Mürsel ÖZDOĞAN
      Abstract: The present review asessessed meat quality taking into account complex and multivariate qualities including meat production. Production conditions; however, consist of management system, breeding, genotype, feeding, holding and stunning before slaughtering, method of slaughter, cooling and storing conditions. Meat quality changes depending on many factors such as feed, level of feeding, weaning age, castration, slautering age, etc. Today, animal nutritionists have developed new nutrition strategies to improve meat quality by changing the feed composition of poultry and small/large ruminant. Also, animal nutrition can affect gene expression in the animal via epigenetic effects varying the differentiation and proliferation of adipose cells. Scientists can use different feedstuffs to modulate the expression of target genes and increase meat quality.

  • In the light of studies in the World, Denizli local chicken breed

    • Authors: Tülin AKSOY; Doğan NARİNÇ, Ali AYGÜN
      Abstract: The purpose of this article is to provide information about the conservation of local genetic resources and in the light of these, what can be done on the Denizli native chicken breed. Turkey, located in a transition region, have only two registered local chicken breeds as Denizli and Gerze. Native chicken breeds are those resources that should be conserved for maintaining genetic variation. Domestic chicken breeds, which are resistant to the adverse conditions in their region, are especially suitable genetic materials for alternative grazing systems where chickens are more exposed to adverse environmental conditions. Increasing their yield by selection will positively affect the profitability of alternative systems. Denizli breed is more suitable for genetic breeding studies because of its higher productivity for body weight and egg production than Gerze. In addition, it may be possible to produce geo-labelled chicken meat and eggs using Denizli breed due to its high level of recognition and being the symbol of a city. Many studies have been conducted on the phenotypic and genetic characterization of native chicken breeds in many countries. The next step is the breeding of native breeds by selection. In Turkey, these studies should be started as soon as possible since they will reveal the heritability and genetic correlations, which are the first steps for the genetic improvement of the breed.

           of Ağrı Province: Milking Management Practices

    • Authors: Rıdvan KOÇYİĞİT; Mete YANAR, Recep AYDIN, Veysel Fatih ÖZDEMİR, Abdulkerim DİLER, Ahmet YILMAZ
      Abstract: Objective: In this study, it was aimed to determine the current situation of milking management practices of the dairy cattle enterprises in the central county of Ağrı province and to propose some solutions in consideration of the revealed problems. Material and Method: Survey data obtained from 400 dairy cattle enterprises in the central county of Ağrı province constituted the material of the study. Results: It was determined that in 25.2% of the surveyed enterprises udder cleaning is not performed, and in 93.5% of them the milking is done by hand. The average milk yield of 85.0% of dairy cattle enterprises was between 6-10 liters per animal and only 17.5% of the produced milk was sold. A significant proportion of this milk (95.7%) was marketed as raw milk, and milk in 4.3% of the enterprises was sold after processing into different products such as cheese, yogurt and butter. It was also found out that milk produced in 1.8% of the dairy cattle farms was stored in the cooling tank after milking. 13.6% of the farm owners fed their animals after milking, while 86.3% of them fed them prior to milking. It was also revealed that the calving occurs usually in the winter season and the lactation period of the cows varies between 5-6 months in 57.5% of the enterprises.Conclusion: In order to produce high quality and clean milk in the dairy cattle farms in the central county of Ağrı province, udder cleaning has to be performed properly as well as machine milking should be made widespread. It is necessary to increase the genetic capacity of cows and improve the milking practices of the dairy farms located in the central county of Ağrı province.

           Balıkesir Province

    • Authors: Gamze SANER; Sait ENGİNDENİZ, Hakan ADANACIOĞLU, Duran GÜLER, Zekiye ŞENGÜL
      Abstract: Objective: With the understanding of the value of water buffalo products and the effect of the projects implemented in Türkiye after 2010, water buffalo breeding has gained importance. This research aims to analyze economical aspect of the water buffalo farms within the scope of the Buffalo Breeding Project in the Hands of the People in Balıkesir province.Material and Methods: The data was obtained through face to face questionaire from 102 producers in the districts of Altıeylül and Gönen of Balıkesir Province in which buffalo milk production was done intensively. Within the scope of the research, whether there is a difference between the characteristics of the water buffalo farms according to the size of the farms (1-10 heads, 11-20 heads and 21 heads and above) was statistically tested with Kruskal-Wallis test.Results: In the study, average milk yield was found as 1332.89 kg in one lactation per buffalo. This amount is above the Türkiye’s average of 2019 (1000.10 kg). The total daily feed consumption is 12.32 kg per buffalo. According to the average of farms, net profit per animal unit is 1484.31 TL. It has been determined that the gross profit of the small size enterprises was higher, and these farms convert the milk into value-added products and market them in line with their own possibilities. Conclusion: According to the results, for the economic sustainability of buffalo farming, it is necessary to supporting the sector and direct the producers to the buffalo products with high added value. Thus, migration from villages to cities will be prevented and producers will be able to breed buffaloes under more modern and technical conditions.

  • Phenotypic Correlations between Carcass Part Yields and Meat Quality
           Characteristics in Quails

    • Authors: Hüseyin Cem GÜLER
      Abstract: Objective: This study aimed to determine phenotypic correlations between carcass part yields (breast and thigh yield) and meat quality characteristics (pHu, lightness, redness, yellowness, chroma, hue, thawing loss, cooking loss, water holding capacity, and texture) in Japanese quails.Material and Methods: This study was carried out on a total of 130 Japanese quails with mixed sexes. Twenty-four hours after slaughter, pHu and color measurements were performed in the right breast muscle to determine meat quality characteristics.Results: Mean breast and thigh muscle yields were determined as 24.19% and 14.41%, respectively. Significant phenotypic correlations were found for carcass part yields and meat quality characteristics in quail meat. While determined negative significant (p<0.05) phenotypic correlations for pHu and lightness (-0.193), yellowness (-0.288), chroma (-0.266), and thawing loss (-0.248); pHu’s relationships with redness, hue, water holding capacity and, texture were insignificant.Conclusion: In this study, the significant negative phenotypic correlation determined between pHu and lightness shows that selection for breast meat lightness in quails can affect the ultimate pH and lead to an improvement in quality characteristics, and this situation can be used to reduce meat quality defects.

  • The Effects of Stocking Density on Performance and Slaughter Traits in
           Guinea Fowls

    • Authors: Mehmet Akif BOZ; Kadir ERENSOY, Ahmet UÇAR, Musa SARICA
      Abstract: Objective: In this study, it was aimed to determine the growth performance, feed intake, slaughter and carcass traits of guinea fowls reared at three different stocking densities.Material and Methods: The study was carried out with a total of 252 guinea fowls reared in three different stocking densities (6.6, 9.3, 12 guinea fowls per m2) in the closed-barn system. The body weight, feed intake and feed conversion ratio were determined at the day-old, 2, 4, 6, 8, 10, 12 and 13 weeks of age. Slaughter and carcass traits were determined at 13 weeks.Results: In the study, lower body weight was determined in the high stocking density group at the 6th week and onwards. Cumulative feed intake was higher in guinea fowls reared at low stocking density after the 4th week. However, the feed conversion ratio was higher in the low stocking density group at the 6th week and onwards. There was no significant effect of stocking density on slaughter and carcass weights and percentages.Conclusion: Stocking density significantly affected body weight, feed intake, feed conversion ratio and mortality, however did not affect slaughter and carcass traits in guinea fowls at 13 weeks of age. Our study results showed that the most economical production in terms of growth performance and production costs can be achieved with 9-10 guinea fowl per unit area. However, for alternative poultry species such as guinea fowl, further studies are needed to show the effects of production in closed-barn systems, which are very different from their natural habitats, on the welfare status and natural behavioral characteristics

  • Polymorphism of the Calpastatin (CAST) and Growth Differentiation Factor 9
           (GDF9) genes in Akkaraman Sheep Breed

    • Authors: Koray KIRIKÇI
      Abstract: Objective: In this study, the gene polymorphisms of Calpastatin (CAST) and Growth Differentiation factor 9 (GDF9) were determined in Akkaraman sheep breed.Material and Methods: Genomic DNA was obtained from blood samples of 50 Akkaraman sheep. All samples for CAST and GDF9 were genotyped by the Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) method using the enzymes MspI and Hhal.Results: Three (MM, MN, and NN) and two (GG and GA) genotypes, respectively, were detected at the CAST and GDF9 genes. The frequencies of the genotypes MM, MN and NN were determined to be 44 %, 54 % and 2 %, respectively. The frequencies of the GG and GA genotypes were found to be 84 % and 16 %, respectively. The AA genotype was not found.Conclusion: The study showed for the first time that the Akkaraman breed carries the GDF9 G1 mutation and has sufficient variation in the CAST. Previous studies provided that both genes can be used as biomarkers for increasing lambing yield and growth rates. Therefore, in order for the studied genes to be used as biomarkers in the Akkaraman breed, association studies should first be performed.
