Effects of some factors on gestation length in Hamdani, Morkaraman and Karakul sheep

Bu çalışma, Hamdani, Morkaraman ve Karagül koyunlarının gebelik süresi üzerine ırk, tohumlama mevsimi, koyunun yaşı, doğum tipi, kuzunun cinsiyeti ve doğum ağırlığının etkilerini araştırmak amacıyla yapılmıştır. Araştırmada, Hamdani, Morkaraman ve Karagül koyunlarının doğumlarına ait 259 veri analiz edilmiştir. Hamdani, Morkaraman ve Karagül koyunlarında gebelik süresi sırasıyla 149.77±0.18, 148.76±0.15 ve 147.79+0.19 gün olarak belirlenmiştir. Gebelik süresi ırk tarafından etkilenmiştir (P0.05). İki yaşlı koyunlann gebelik süresi (148.76±0.17 gün) ile 4 yaşlı koyunların gebelik süresi (148.78±0.12 gün) benzer bulunmuştur (P>0.05). Tek doğum yapan koyunlann gebelik süresi (149.36+0.11 gün), ikiz doğum yapan koyunların gebelik süresinden (148.18±0.21 gün) daha uzun sürmüştür (P

Hamdani, Morkaraman ve Karakul koyunlarında gebelik süresine bazı faktörlerin etkisi

This study was carried out to investigate effects of breed, mating season, age of ewe, birth type, sex of lamb and birth weight on gestation length in Hamdani, Red Karaman and Karakul ewes. In the study, data on 259 lambings of Hamdani, Red Karaman and Karakul sheep were analyzed. Gestation length for Hamdani, Red Karaman and Karakul ewes were 149.77±0.18, 148.76±0.15 and 147.79±0.19 days, respectively. Gestation length was affected by breed (P0.05). Gestation lengths of 2-yr-old ewes (148.76±0.17) and 4-yr-old ewes (148.78+0.12) were similar (P>0.05). Gestation length of ewes which gave birth to single lambs (149.36±0.11) were longer than those which gave birth to twin lambs (148.18±0.21) (P
