Abstract

The aim of this study was to determine the potential effect of non-genetic factors on certain production characteristics of Hair goats raised under semi-intensive management and dry- sub humid conditions, and to investigate phenotypic correlations between these traits. A generalized linear model was used to investigate the effect of non-genetic factors on gestation length (GL), number of services per conception (NSPC), lactation length (LL), lactation milk yield (LMY) and daily milk yield (DMY), while the Chi-square method was used to evaluate other fertility parameters. The pregnancy rate, birth rate and single-birth rate in the Traditional Group were higher, while the infertility rate and NSPC were lower, than those in the Artificial Group (P<0.001). Furthermore, it was determined that LL, LMY and DMY increased (P<0.001), the NSPC decreased (P<0.001), and birth and twinning rates fluctuated (P<0.01) as age increased. The best fertility and milk yield characteristics were in the ≥5 year-old-goats and live weights of 45.0-49.9 kg. In addition, it was determined that kid yield was increased in the goats synchronized with intravaginal sponges impregnated with fluorogestone acetate and in those bred via the traditional method.

Özet

Bu çalışmanın amacı, yarı entansif ve kurak az nemli iklim koşullarında yetiştirilen Kıl keçilerinin döl verimi ve süt verimi üzerine genetik olmayan faktörlerin etkisini belirlemek ve bu faktörler arasındaki fenotipik korelasyonu araştırmaktır. Gebelik süresi (GL), gebelik başına düşen tohumlama sayısı (NSPC), laktasyon uzunluğu (LL), laskyason süt verimi (LMY) ve günlük süt verimi (DMY) üzerine genetik olmayan faktörlerin değerlendirilmesinde Genear linear model, diğer döl verim parametrelerinin değerlendirilmesinde ise Chi-square metodu kullanılmıştır. Tabii tohumlama yapılan gruptaki keçilerin gebelik oranı, doğu m oranı ve tek doğum oranı suni tohumlama uygulananlardan daha yüksek iken, NSPC sayısı daha düşüktür. Yaş arttıkça LL, LMY ve DMY artmış (P<0.001), NSPC azalmış (P<0.001), tek ve ikiz doğum oranları ise dalgalanma göstermiştir (P<0.01). En iyi döl verimi ve süt verimi nin 5 ve daha yukarı yaşlı ve 45.0-49.9 kg canlı ağırlığındaki keçilerde olduğu belirlenmiştir. Fluorogestone acetate içeren intravajinal sünger ile senkronizasyon ile tabii tohumlama uygulaması nın keçilerde oğlak verimini arttırdığı sonucuna varılmıştır.
