Abstract
Bu araştırma İvesi, Ost-Friz x İvesi melezi (F1) kuzularda büyüme, yaşama gücü ile bazı vücut ölçülerinin belirlenmesi amacı ile yapılmıştır. Araştırma için gerekli veriler, süt emme döneminde 23’er baş, İvesi ve Ost Friz x İvesi melezi (F1) ile, vücut ölçüleri ise 11’er baş saf ve melez dişi tokludan elde edilmiştir. Kuzuların vücut ölçüleri bakımından gruplar arası farkın karşılaştırması t-testi ile yapılmıştır. İvesi ve Ost-Friz x İvesi melezi (F1) kuzularda ortalama doğum ağırlığı, sırası ile 4.15 ve 4.64 kg, sütten kesim ağırlığı (105. gün yaşı) 15.39 ve 18.31 kg, sütten kesime kadarki dönemde yaşama gücü %82.61 ve %86.96 olmuştur. İvesi ve Ost-Friz x İvesi melezi (F1) 1 yaşlı dişilerde sırası ile vücut uzunluğu 63.40 ve 73.90 cm, göğüs çevresi 98.20 ve 104.20 cm, cidago yüksekliği 60.10 ve 66.50 cm bulunmuştur. Bu araştırma sonucunda melezleme ile İvesi ırkının doğum ağırlığı ve 105. gün canlı ağırlının arttığı tespit edilmiştir. Bu nedenle İvesi ırkının, Ost-Friz ile melezlenmesi ekonomik verimlerinin artırılabileceğini ortaya koymuştur.
The aim of this study was to determine of growth rate, survival ability and some body measures of Awassi and East Friesian x Awassi (F1) crossbred lambs. In the study, growth characteristics and survival ability were determined in 23 Awassi and 23 East-Friesian x Awassi (F1) crossbred lambs. Body measurements were obtained from 11 Awassi and East-Friesian x Awassi (F1) crossbred yearlings. Comparisons between the groups with regard to body measures were made using student’s t test. Average body weights at birth for Awassi and East-Friesian x Awassi (F1) lambs were 4.15 and 4.64 kg, respectively. The average weights on weaning at 105th day for Awassi and East Friesian x Awassi (F1) were 15.39 kg, 18.31 kg respectively. For the groups, the average survival ability were 82.61 and 86.96 %, respectively. In one year old female Awassi and East-Friesian x Awassi (F1) yearling lambs, average body length, chest circumference and withers hight were 63.40 and 73.90 cm, 92.80 and 104.20 cm and 61.10 and 66.50, cm respectively. Our results indicate that Awassi lambs birth weight and the average body weights on the 105th day were increased by crossbreeding. In the light of these, it can be concluded that results, crossbreeding between Awassi East Friesian x Awassi (F1) results in increasied economical benefits
