(Afyon Kocatepe Üniversitesi Veteriner Fakültesi, 2022) Budak, Duygu; Doğan Daş, Besime; Çamkerten, Güzin; Kal, Yavuz
In this study were used 40 newborn singleton Akkaraman and Merino lambs with 4 trial groups consisting of selected 10 lambs homogeneous according to race and gender. Trial was carried out 100 days, covering 5 feeding periods with 21-day periods the first application is on the 14th day from the birth of lambs. The lambs were fed with lamb starter feed for the first two months, then with lamb grower feed ad-libitum and 250 g/day/head dry alfalfa hay. At the end of the study; it was determined that the lowest total antioxidant status (TAS) was in Akkaraman male lambs, the highest was in Merino’s female, and it was found higher in Merino females than males (P<0.05). There was no difference between the groups in terms of total oxidant status (TOS) and native thiol (NTL), during the trial (P?0.05). Oxidative stress index (OSI) obtained from Akkaraman lambs was found to be higher than Merino, lower OSI was reached in female Merino's, and total thiol (TTL) were increased in Merino male lambs compared to Akkaraman (P<0.05). It was concluded that the Merino had better adaptation to feeding after weaning than the Akkaraman.
