Öğe A Research on Structural Characteristics and Problems of Sheep Breeding in Nigde(KAHRAMANMARAS SUTCU IMAM UNIV, 2015) Ceyhan, Ayhan; Sekeroglu, Ahmet; Unalan, Adnan; Cinar, Mahmut; Serbester, Ugur; Akyol, Ethem; Yilmaz, ErdoganThis study was carried out to reveal the present status of sheep farms in Nigde, to detect basic priority problems and to offer some solutions to these problems. In this study, total of 96 sheep farming enterprises were chosen by stratified sampling method to represent the entire province as an example. A survey was conducted to obtain information regarding mating, lambing, milking, shearing, marketing milk and meat, grazing animals status, tools and equipment of sheep enterprises and health protection and feed utilization status. The results of analyzes showed that a large portion (68.8%) of sheep breeders were primary school graduates, while 99% of sheep farms raised only Akkaraman breed 1.0% of them raised only Merino breed, average duration of sheep breeding was 25.7 years, family labor was commonly (63.5%) used as shepherd, the average number of sheep per farm was 314.5 head and the enterprises had also 7.9 head cows, 38.1 head goats, 1.9 horses and 5.2 heads cat and dog. Besides, it was informed that 86.4% of breeders had learned sheep breeding from their ancestors, sheep farming was only source of income for 82.3% of them and was enjoyable job for 10.4% of them. It was also determined that sheep breeding was maintained in highland (40.6%), in highland and settled down (19.8%), in settled down (38.6%), and in nomadic (1.0%) system in Nigde. The 97.9% of sheep enterprises is a member of Nigde Sheep and Goat Breeders Association. Breeders expressed that high feed prices, insufficient pastures area and poor pastures quality were priority problems. They reported that needs to be done to increase in marketing price, improvement of pasture and sheep flock genetic, also increasing the forage crops cultivation area for profitable sheep breeding.Öğe Determination of Boron Level in Feeds Used in Cattle Nutrition in Regions of Central Anatolia and Mediterranean of Turkey(Kahramanmaras Sutcu Imam Univ, 2013) Serbester, UgurIn this study, samples of forage (alfalfa hay, corn silage, silage of common vetch with triticale, wheat straw), feed ingredient (barley grain, corn grain, wheat grain, wheat bran, corn meal, corn bran, corn gluten meal, cottonseed meal, soybean meal, sunflower meal, dried digestible grain solubilty), and concentrate feed (calf grower feed, heifer feed, dairy cattle feed and beef cattle feed) were collected from various feed mills and dairy cattle farms in the Central Anatolia and Mediterranen Regions of Turkey and analysed to determine their boron levels. Boron concentration ranged from 23.9 to 39.1 ppm in forages. In feed ingredients, concentrations of B varied between 4.1 and 36.4 ppm, with barley grain and soybean meal having the lowest and highest levels, respectively. Average B concentration of concentrate feeds was 20.1 ppm and beef cattle feed and heifer feed had the lowest (12.0 ppm) and highest values (27.9 ppm), respectively.Öğe Effect of somatic cell count on milk yield and composition of first and second lactation dairy cows(PAGEPRESS PUBL, 2015) Cinar, Mahmut; Serbester, Ugur; Ceyhan, Ayhan; Gorgulu, MuratThis study was carried out to investigate the effect of somatic cell count (SCC) on milk yield and milk composition in first and second lactation Holstein dairy cows. Thirty cows in first lactation and 49 cows in second lactation were used in the study. Animals were 15 +/- 9.87 days in milk. Individual milk samples were collected monthly from June 2009 to March 2010, and somatic cell counts, milk protein, milk fat, lactose and milk urea-N were determined. Four SCC groups were formed for determining effect of SCC on milk yield and composition. These groups were as follows: <= 200, 201-500, 501-999, and >= 1.000x10(3) cell/mL. It was observed that SCC had a high significant effect on milk yield, milk protein, milk lactose (P<0.01), total solids and milk urea-N (P<0.05), however, the effect of SCC on milk fat was not significant (P>0.05). This study indicates that high SCC negatively affects not only milk yield but also milk composition and quality.Öğe Kid growth performance and reproductive characteristics of Hair goats raised under breeder conditions(Tubitak Scientific & Technological Research Council Turkey, 2022) Ceyhan, Ayhan; Cinar, Mahmut; Serbester, UgurIn the study, fertility parameters of Hair goats and the growth performance of kids raised under farmer conditions were investigated. The data of birth weight of 28,768 kids, the body weight of 27,541 kids aged d 90, and reproductive parameters of 26,693 does were used between 2013 and 2017 years. The birth weights of Hair goat kids born in 2013, 2014, 2015, 2016, and 2017 years were 2.36, 2.46, 2.56, 2.61, and 2.61 kg, whereas body weights detected on the d 90 were 15.2, 12.7, 12.8, 13.1, and 14.5 kg, respectively. Year, sex, birth type, and age of does affect significantly the birth and body weight of the kids on d 90 (p < 0.01). The survival rate detected on d 90 of kids was 100%, 98.7%, 94.5%, 93.9%, and 91.8% in 2013, 2014, 2015, 2016, and 2017 years, respectively. The effect of year on the viability of kids was found to be statistically significant (p < 0.01). Twinning rates of does were 3.5%, 5.7%, 9.5%, 12.4%, and 6.5%; kid yields per birth was 1.00, 1.00, 1.09, 1.12, and 1.00 in 2013, 2014, 2015, 2016, and 2017 years, respectively. The average birth rate was 91.9%, whereas the infertility rate was 8.1%. It was concluded that year, sex, and birth type influenced the kid growth performance of Hair goats due to variations in environmental factors such as management and feeding system. Therefore, if the management practices, nutrition, and health issues are improved, the growth performance of Hair goat kids and some reproductive parameters of Hair goats may be better.Öğe Negative Energy Balance in Dairy Cattle and Its Metabolic Indicators(KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2012) Serbester, Ugur; Cinar, Mahmut; Hayirli, ArmaganEnergy balance, simply, is the difference between energy consumed and sum of energy used for maintenance and production. The negative difference indicates body reserves being mobilized, whereas the positive difference indicates body reserves being replenished or increased. Negative energy balance (NEB) is accepted as natural event in dairy cattle because, dry matter intake decrase during the close-up period and increases more slowly than milk yield after parturition. Other than phenotypical changes (body weight and condition score change), metabolic indicators in blood and milk (nonesterified fatty acids, ketone bodies, milk fatty acid composition, and milk fat:protein ratio, etc.) also change, which can be used for estimating severity and duration of NEB. This review emphasizes causes of NEB, metabolic indicators that may be used to estimate NEB, and important points in their interpretations.
