Improvement studies on mutton sheep for Marmara region conditions: I. fertility, lamb survival, and growth traits of lambs

Öz:

Bu araştırma, Alman Siyah Başlı Et (ASB) ırkı koçlar ile Kıvırcık ırkı koyunların melezlerinde döl verimi, kuzuların yaşama gücü ve büyüme özelliklerini karşılaştırmak amacı ile yürütülmüştür. Çalışmada, ASB × K (F1), Bandırma-I, Bandırma-II ve Kıvırcık koyunlarının doğum oranı sırasıyla % 80,00, % 75,73, % 76,78 ve % 83,72’dır. Doğum oranı bakımından genotipler arasındaki farklılıklar önemlidir (P < 0,01). Doğumda kuzu verimi üzerine genotiplerin etkisi önemli (P < 0,05) ancak, koçaltı koyuna göre kuzu verimi üzerine etkisi önemsizidir (P > 0,05). Sütten kesimde yaşama gücü oranı bakımından genotipler arasındaki farklılıklar önemlidir (P < 0,01). Kuzuların doğum ağırlığı, sütten kesim ağırlığı ve bir yaş canlı ağırlıkları ASB × K (F1)’ler için sırasıyla; 3,77 kg, 34,11 kg ve 43,71 kg, Bandırma-I kuzuları için 3,74 kg, 32,98 kg ve 44,91 kg, Bandırma-II kuzuları için 3,73 kg, 33,18 kg ve 45,71 kg ve saf Kıvırcık kuzuları içinde kg 3,45 kg, 30,92 kg ve 42,22 kg’dır. Bu araştırmadan elde edilen bulgular, Kıvırcık koyunların ASB ırkı ile melezlenmesinin kuzu verimini artırmadığını, ancak elde edilen melez kuzuların yerli ırk Kıvırcıklar ile karşılaştırıldığında önemli yaşama gücü problemine sahip olmadığını ve Marmara Bölgesi koşullarında Kıvırcık ırkından daha yüksek büyüme performansına sahip olduğunu göstermiştir.

The present study was conducted to compare the fertility of ewes, the survival rates, and the growth performance of lambs that were crossbred by mating German Black-Headed Mutton (GBM) rams with Kıvırcık ewes. Th e average lambing rates of the GBM × K(F1), Bandırma-I and Bandırma-II genotype, and Kıvırcık ewes were 80.00%, 75.73%, 76.78%, and 83.72%, respectively. Th e diff erences in lambing rates between the genotypes were signifi cant (P < 0.01). Th e genotypes had a signifi cant eff ect on litter size at birth, but not on fecundity. Th e diff erences in lambs’ survival rates between the genotypes were signifi cant (P < 0.05). Th e birth weight (BW), weaning weight (WW), and yearling live weight (YLW) of the lambs were 3.77 kg, 34.11 kg, and 43.71 kg for the GBM × K (F1); 3.74 kg, 32.98 kg, and 44.91 kg for the Bandırma-I; 3.73 kg, 33.18 kg, and 45.71 kg for the Bandırma-II; and 3.45 kg, 30.92 kg, and 42.22 kg for the Kıvırcık lambs. Th e results of this study showed that crossbreeding between the GBM and Kıvırcık breed did not signifi cantly increase lamb production. However, crossbred lambs did not have signifi cant survival problems when compared to native Kıvırcık lambs and had higher growth performance than purebred Kıvırcık lambs.
