Özet
Bu araştırma ekstansif şartlarda Karakaş-Akkaraman koyunlarının süt verim özelliklerini araştırmak amacıyla yapılmıştır. Araştırma Van ili Edremit ilçesinde yürütülmüştür. Araştırmada 70 baş Karakaş-Akkaraman koyun kullanılmıştır. Karakaş-Akkaraman koyunlarının laktasyon süt verimi, laktasyon yağ oranı ve laktasyon süresi sırasıyla 50.50 kg. % 6.60 ve 144.90 gün olarak tespit edilmiştir. Laktasyon süt verimi üzerine doğum tipi ve yaşın etkisi önemli (P<0.05, P<0.001). laktasyon başı canlı ağırlığın etkisi önemsiz; laktasyon süresi üzerine yaşın etkisi önemli (P<0.01), doğum tipi ve laktasyon başı canlı ağırlığın etkisi önemsiz; laktasyon yağ oranı üzerine ise doğum tipi, yaş ve laktasyon başı canlı ağırlığın etkisi önemsiz olmuştur. Laktasyon süt verimi ve laktasyon süresi arasında 0.90 (P<0.001), laktasyon süt verimi ve laktasyon yağ oranı arasında -0.46 (P<0.001) düzeyinde fenotipik korrelasyon katsayıları belirlenmiştir.
This study was carried out to investigate milk yield characteristics of Karakaş- Akkaraman ewes in extensive conditions. The study has been conducted on 70 Karakaş-Akkaraman ewes in Edremit, Van. Lactation milk yield, lactation milk fat percentage and lactation length in Karakaş-Akkaraman ewes were 50.50 kg. 6.60 % and 144.90 days, respectively. The effects of birth type and age on lactation milk yield were significant (P<0.05, P<0.001), but the effect of live weights of ewes at the initiation of lactation was not significant, the effect of age on lactation length was significant (P<0.01), but the effects of birth type and live weights of ewes at the initiation of lactation were not significant furthermore, the effects of birth type, age and live weights of ewes at the initiation of lactation on lactation milk fat percentage were not significant. The fenotypic correlation coefficient between lactation milk yield and lactation length which was found 0.90 (P<0.001), the fenotypic correlation coefficient between lactation milk yield and lactation milk fat percentage which was found - 0.46 (p<0.001).
