Abstract
Bu çalışma, Uludağ Üniversitesi Veteriner Fakültesi Çiftligi koşullarında yetiştirilen Esmer ırk ineklerin bazı dölverimi özelliklerinin belirlenmesi ve özelliklere etki eden çevre faktörlerinin incelenmesi amacıyla yapılmıştır. Araştırmada Esmer ineklerin 1988- 1996 yılları arasında servis periyodu, gebelik başına tohumlama sayısı, buzağılama aralığı ve gebelik süresi minimum kareler ortalamaları sıras a I 14.6 giln, 2. 11 tohumlama, 402.7 giln ve 284.9 giln saptanmıştır. Yılların servis sayısı ve gebelik süresine etkisi istatistiki düzeyde önemli bulunmu tur (P 05-P O). Buzağılama ırası ve mevsimlerin dölverimi özelliklerine etkisi gebelik süresi hariç istatistiki düzeyde önemli bulunmamıştır.
This study was done to investigate the levels of some reproductive characteristics of Brown Swiss cows raised under the condition of the Uludag University, Faculty of Veterinary Medicine Farm. In this study, least square means of service period, service number for per conception, calving interval and gestation Ienght were determined as 114.6 days, 2.11, 402.7 days and 284.9 days respectively, between the years of 1988 and 1996. The effect years on service number for per conception and gestation fengbt was found statistically important (P -0 0. It was found that calving number and calving season had no effect on reproductive characteristics stastistically, except for gestation lenght.
