The growth and survival characteristics of lambs produced by commercial crassbreeding kıvırcık ewes with F2 rams with the German Black-Headed mutton genotype

Bu araştırma, Kıvırcık koyunlarının Alman Siyah Başlı Etçi Koyunu (ASB) x Kıvırcık (F2) ve ASB x Merinos (F2) genotiplerindeki koçlarla birleştirilmesi ile elde edilen melez kuzuların büyüme ve yaşama güçlerinin birbirleri ile ve saf Kıvırcık kuzularla karşılaştırılması amacıyla yürütülmüştür. Araştırma için gerekli veriler, 59'ar baş (ASB x Kıvırcık) x Kıvırcık ve (ASB x Merinos) x Kıvırcık kuzu ile 60 baş saf Kıvırcık kuzudan elde edilmiştir. (ASB x Kıvırcık) x Kıvırcık, (ASB x Merinos) x Kıvırcık ve saf Kıvırcık kuzularda ortalama doğum ağırlığı sırasıyla 4,08 kg, 4,32 kg ve 3,85 kg olarak elde edilmiştir. Doğum ağırlığı için genotip grupları arasındaki farklar istatistiki açıdan önemli bulunmuştur (P < 0,001). Bu gruplarda kuzuların sütten kesim ağırlıkları sırasıyla 19,33 kg, 19,38 kg ve 17,58 kg olarak bulunmuştur. Sütten kesim ağırlığı için melez genotipler arasındaki farklılık önemli bulunmazken (P > 0,05), melez kuzular ile saf Kıvırcık kuzular arasındaki faklılık önemli bulunmuştur (P < 0,05). Kuzularda büyüme üzerine genotip, doğum tipi, cinsiyet ve ana yaşının etkisi incelenmiştir. Ana yaşı dışındaki diğer etkiler önemli bulunmuştur. Kuzuların sütten kesimdeki yaşama gücü değerleri sırasıyla % 88,13, % 91,53 ve % 90,00 olarak bulunmuştur. Bu araştırmada elde edilen bulgular, ASB genotipi taşıyan F2 koçlar kullanılarak elde edilen melez kuzuların saf Kıvırcık kuzulardan daha iyi büyüme performansına ve saf Kıvırcık kuzulara benzer yaşama gücüne sahip olduklarını göstermektedir.

This study was conducted to compare the growth and survival characteristics of crossbred lambs produced by mating Kıvırcık ewes with German Black-Headed Mutton (GBM) x Kıvırcık (F2) rams, GBM x Merino (F2) rams, as well as the growth and survival characteristics of purebred Kıvırcık lambs. The data were obtained from 59 (GBM x Kıvırcık) x Kıvırcık, 59 (GBM x Merino) x Kıvırcık, and 60 purebred Kıvırcık lambs. The birth weights of (GBM x Kıvırcık) x Kıvırcık, (GBM x Merino) x Kıvırcık, and purebred Kıvırcık lambs were 4.08, 4.32, and 3.85 kg, respectively. The differences of birth weight between the genotype groups were statistically significant (P < 0.001). The weaning weights of these groups were 19.33, 19.38, and 17.58 kg, respectively. The difference in weaning weights between the crossbred genotypes was not significant (P > 0.05), whereas the differences between the crossbred lambs and the purebred Kıvırcık lambs were significant (P < 0.05). The effects of genotype, birth type, sex, and age of dam on the growth of lambs were investigated. All these effects, except age of dam, were significant. Among the genotypes, 88.13%, 91.53%, and 90.00% of the lambs survived to be weaned, respectively. The results of this study showed that crossbred lambs produced by the use of F2 rams, which carry the GBM genotype, had higher growth performance than purebred Kıvırcık lambs, although they had similar survival rates.
