Abstract

In this study, estrus and calving records of Anatolian water buffaloes were analysed to investigate the influence of climatic conditions and birth weight on the age at first fertile estrus of Anatolian water buffaloes. The highest sexual activity (59.8 %) was found between 800 and 1100 days, and the average age at first fertile estrus was 917.7 ± 103.3 days (33 months approximate). More than half (52.4 %) of the total animals showed a climatic conditional pattern concentrated between June and August which is the warmest period of the year. Although year, season, birth weight (31.3 ± 0.8 kg), day length and relative humidity had no significant effects on age at first fertile estrus, the effects of rainfall and ambient temperature were found significant (P< 0.10) at a lower rate.

Özet

Bu çalışmada, Anadolu mandalarının östrus ve buzağılama kayıtları, ilk fertil östrus yaşları üzerine doğum ağırlığı ve iklim koşullarının etkisini araştırmak için değerlendirildi. En yüksek seksüel aktivite (%59.8) 800-1100 gün arasında belirlendi ve ortalama ilk fertil östrus yaşı 917.7 ± 103.3 gün (yaklaşık 33 ay) olarak bulundu. Bütün hayvanların yandan fazlasında (%52.4), yılın en sıcak dönemi olan Haziran ile Ağustos ayları arasında yoğunlaşan iklimsel model gözlendi. Yıl, mevsim, doğum ağırlığı (31.3 ± 0.8 kg), gün uzunluğu ve nisbi nem oranının ilk fertil östrus yaşı üzerine etkisi bulunmamasına rağmen yağış miktarı ve çevre sıcaklığının etkisi düşük düzeyde önemli (P
