Öğe Effect of feeding regime on fatty acid composition of longissimus dorsi muscle and subcutaneous adipose tissue of akkaraman lambs(KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2011) Güler, Gökalp Özmen; Aktümsek, Abdurrahman; Karabacak, AliIn this study, effect of feeding regime on fatty acid composition including conjugated linoleic acid (CLA) of Longissimus dorsi muscle and subcutaneous adipose tissue from lambs were investigated. From same flock, forty-five male Akkaraman suckling lambs, the most common lamb breeds in Turkey, were fed mainly maternal milk from birth to weaning and then were divided into three groups (only maternal milk-fed group, pasture-fed group and concentrate-fed group) at three months of age with an average live weight of 25 kg. Longissimus dorsi muscle from pasture fed-lambs contained significantly more total CLA, n-3 and n-3/n-6 ratio than other groups. In addition, pasture-fed lambs contained significantly more total saturated fatty acid (SFA), CLA, n-3 and n-3/n-6 ratio compared concentrate fed-lambs in subcutaneous adipose tissue. In conclusion, intramuscular muscle and subcutaneous adipose tissue fatty acid composition of lamb can be improved by pasture in the feeding regime.Öğe The Effect of Some Environmental Factors on Birth Weight in Anatolian Merino Sheep(Selçuk Üniversitesi, 2019) Alçayır, Emine; Karabacak, AliIn this study, the data of 1510 lambs born in a private sheep farm in Eregli district of Konya in 2018-2019 were evaluated. Birth type, birth times, birth weight and lamb sex were investigated in this study. 892 of the lambs were born in 2018 and 618 of them were born in 2019. A total of 1510 lambs were born. 699 of them were born as single, 761 of them as twins and 50 of them as triplets. The total number of sheep was 1096. 681 of the lambs were male and 829 were female. Of the environmental factors affecting birth weight, while the effect of the year was statistically insignificant (p <0.05), the effect of season, type of birth and sex was significant (p <0.01). Lambs born in spring have more live weight than those born in other seasons. The live weight of male lambs was higher than that of females, however the weight of single born lambs was higher than that of twins and triplets.Öğe The Effect of Some Environmental Factors on Diurnial Distribution of Births in Anatolian Merino Sheep(Selçuk Üniversitesi, 2019) Uğur, Koray; Karabacak, AliIn this study, data on the daily distribution of births of Central Anatolian Merino sheep reared in Sheep Breeding Department of Bahri Dağdaş International Agricultural Research Institute was evaluated. In this study, the effects of dam age, sex of lamb and type of birth on the time of birth in sheep were investigated. A day (24 hours) was divided into four timeframes as 22: 01-04: 00, 04: 01- 10: 00, 10: 01-16: 00 and 16: 01-22: 00 in order to determine the time period in which births take place. Chi-square (?2) test was used to determine whether the age, sex, and type of birth were effective on the distribution of births to the time periods during the day. As a conclusion, it was sind out that, in 2016, 78.09% of births were single and 21.91% twins. The sex ratio was 48.24% male and 51.76% female. The most frequent birth times were 10: 01-16: 00 (26.95%) and 04: 01-10: 00 (25.57%), the earlier birth times were 16: 01-22: 00 (23.93%) and 22: 01- 04:00 (23.55%). The effect of dam age and lamb sex on delivery time was significant (P<0.05), but the effect of birth type was not significant.Öğe Ereğli yöresi süt sığırı hayvan barınaklarının yapısal durumu ve sorunların tespiti(Selçuk Üniversitesi Fen Bilimleri Enstitüsü, 2000-01-28) Karabacak, Ali; Topak, RamazanBu Çalışma Ereğli ilçesi ve bazı köylerindeki bağlı-duraklı süt sığırı barınaklarının yapısal durumunun ve sorunlarının tespiti gayesi ile yapılmıştır.

Bu amaçlaTürkiye için, 1986-2016 yılları arası veriye dayanarak süt ve dana eti için ayrı ayrıdenklemlerle hata düzeltme modelleri tahmin edilmiştir. Eşbütünleme ilişkisinden kısadönem Granger nedensellik ilişkilerine bakıldığında, süt üretim denkleminde değişkenlerarasında istatistiksel olarak anlamlı bir nedensellik ilişkisi bulunamamıştır. Dana etiüretim denkleminde ise tüm değişkenler arasında çift yönlü Granger anlamda nedensellikbulunmuştur. Uzun dönem katsayılar incelendiğinde, süt üretim seviyesi ile piyasa fiyatfarklılaşması arasında negatif, üretici destekleri ile pozitif bir ilişki bulunmaktadır. Öteyandan dana eti üretimi ile piyasa fiyat farklılaşması arasında pozitif ancak üreticidestekleri ile negatif bir ilişki bulunmaktadır. Bulgular gerek parasal üretici destekleriningerekse de parasal destek dışındaki dış ticaret düzenlemesi gibi politikaların ürün türünegöre farklılaştırılması gerektiği düşüncesini desteklemektedir.
