Abstract
Bu araştırma, yetiştirici koşullarında 6-7 haftalık yaşta sütten kesilerek besiye alınan ve kaşak besi uygulanan Merinos X Kıvırcık melezi erkek ve dişi kuzuların besi performansını saptamak amacıyla düzenlenmiştir. Araştırma 97 baş erkek ve 103 baş dişi olmak üzere toplam 200 baş kuzuyla yürütülmüş olup, besi 60 gün sürmüştür. Kuzular 100'er başlık 2 gruba ayrılarak dişi-erkek bir arada besiye alınmış ve 1. gruptaki kuzular sütten kesimden hemen sonra besiye alınırken , 2. gruptaki kuzular besi süresince analarını emmişler ve çiftlikte uygulanan geleneksel kaşak yöntemle beslenmişlerdir. Erken sütten kesilen kuzular sadece kesit yemle beslenirken kaşak besiye alınanlara ayrıca yonca kuruotu verilmiştir. Besi süresince tüm gruplar ad libitum yemlenmiştir. Her iki gruptaki erkek-dişi kuzuların standardize edilmiş besi başı canlı ağırlığı 15.1 kg, 60 günlük besi süresince toplam ağırlık artışı; 19.5 - 15.1 kg; 19.7 - 16.4 kg ve besi süresince günlük ortalama canlı ağırlık artışı; 324.7 - 252.3 g ; 328.4-274.0 g olarak saptanmış olup, her iki gruptaki farklı cinsiyetteki kuzular arası farklılıklar istatistik önemli (P < 0.01) olduğu halde farklı besi yöntemi uygulanan gruplar arası farklılıklar ise önemsiz bulunmuştur. Deneme süresince grupların günlük ortalama yem tüketimi sırasıyla 0.910 ve 1.068 kg olarak saptanırken, gruplardaki erkek ve dişi kuzuların yemden yararlanma oranları sırasıyla 3.113-4.351 kg; ve 3.540-4.351 kg, 1 kg canlı ağırlık artışının maliyeti ise gruplara göre sırasıyla ; 490-650 TL., 517-625 TL. olarak bulunmuştur.
On farm research was conducted and carried out to find out effects of early weaning and "Kaşak" fattening system on fattening performance of Merino X Kıvırcık crossbred male and female lambs. Animal material of the investigation was 97 male and 103 female lambs. Lambs were alloted to two groups and first group lambs were weaned at 6-7 weeks of age and then conducted to intensive fattening. The second group lambs were conducted to "Kaşak" fattening while they were suckling and continued to suckle their mothers at fattening period. Concentrate feed mixture was given ad libitum in both groups and lambs conducted to "Kaşak" fattening consumed alfalfa hay besides concentrate feed mixture . Fattening period of the groups were 60 days. Standardized initial weight of male - female lambs in the first and second groups were 15.1 kg and total and average daily liveweight gain of the groups at 60 days fattening period were 19.5 - 15.1 kg; 19.7 - 16.4 kg and 324.7 - 252.3 g; 328.4 - 274.0 g respectively. Total and daily liveweight gain differences of male and female lambs were statistically significant (P < 0.01) however differences between different fattening systems were insignificant. Average daily feed consumption of two fattening groups were 0.910 and 1.068 kg. Feed consumption for 1 kg of liveweight gain of male -female lambs at both groups were determined as 3.113-4.351 kg; 3.540-4.351 kg respectively. Cost of 1 kg liveweight gain of male - female lambs at the gropus were estimated as 490 - 650 TL. and 517 - 625 TL .
