Abstract

The many factors may be influence the fertility of dairy cows. Heat stress is a major contributing factor on dairy cows fertility. Lactating dairy cows are especially sensitive to heat stress because they have high metabolic heat production associated with milk production. Sanliurfa is in very hot climate and temperatures in the summer usually reach 41.5 $^oC$. For this reason, this region has many risk factors for dairy cow breeding. This study was conducted to evaluate the relationship between season and fertility. A total of 120 cross bred (Holstein X domestic cattle, Simmental X domestic cattle) cows were used in this study. The cows in oestrus were inseminated artificially in four seasons. The pregnancy diagnosis in cows was performed by rectal palpation at 60-90 days after artificial insemination. As a result of this study, the parturition firs insemination days were 47.5, 51.5, 46.5 and 46.7 in spring, summer, autumn and winter groups, recpectivily (p>0.05). The rates of pregnancy were 70.0%, 46.6%, 60.0% and 56.6% in spring, summer, autumn and winter groups (p>0.05). As a result, the summer groups exhibited significantly lower pregnancy rate compared to the other seasons (p>0.05).

Özet

Sütçü ineklerde fertiliteyi çok sayıda faktör etkilemektedir. Sıcaklık stresi ise bu faktörlerin en önemlilerindendir. Özellikle süt veren inekler, süt üretiminden kaynaklanan yüksek metabolik ısı üretimi sebebi ile sıcaklık stresine daha duyarlıdır. Şanlıurfa çok sıcak bir iklim yapısına sahip olup, yaz aylarında sıcaklıklar çoğunlukla 41.5 $^oC$ye ulaşır. Bu sebeple bu bölge, süt inek yetiştiriciliği için birçok risk faktörüne sahiptir. Çalışmanın amacı, ineklerde mevsimsel farklılığın fertilite ile ilişkisinin ortaya konmasıdır. Çalışmada toplam 120 baş melez inek (holştayn X Yerli, Simental X Yerli) materyal olarak kullanıldı. Değişik mevsimlerde östrusa gelmiş ineklere suni tohumlama yapıldı. Suni tohumlama sonrası 60-90. günlerde ise rektal muayene ile gebelik tespiti yapıldı. Araştırmanın sonucuna göre ilkbahar, yaz, sonbahar ve kış aylarında doğum-ilk tohumlama gün sayısı; 47.5, 51.5, 46.5 ve 46.7dir (p>0.05). Birinci suni tohumlamanın gebelik oranı (%); ilkbahar, yaz, sonbahar ve kış aylarında sırasıyla 70.0, 46.6, 60.0 ve 56.6 olarak tespit edildi (p>0.05). Sonuç olarak, yaz aylarında tohumlanan ineklerin diğer sezonda tohumlananlara göre gebelik oranının istatistiki önemde olmasa da bir düşüşün olduğu saptanmıştır (p>0.05).
