Abstract
In the research, the effect of different initial live weights in ewes on their milk yields, milk components, and live weights of their lambs were investigated in two years and 21 Karayaka sheep. The research was conducted in three periods (1st, 4th and 10th week) until weaning. The heavier sheep have higher mean milk yields (P
Özet
Denemede, 21 adet 2 yaşlı Karayaka koyununda farklı laktasyon başı canlı ağırlıkların süt verimi, süt komponentleri ve kuzuların canlı ağırlıkları üzerine etkisi araştırılmıştır. Araştırma sütten kesime kadarki dönemde 1., 4. ve 10. hafta olmak üzere 3 periyotta yapılmıştır. Ağır koyunlar 1. ve 4. haftalarda hafiflere göre daha yüksek süt verimi göstermişlerdir (P
