Abstract

The aim of this study was to determine the whether the Brown Swiss cattle raised at Regional Agricultural School in Van were inbred and to calculate the effect of inbreeding on age first calving. Mean coefficients of inbreeding were found to be 6.88 ± 0.96 %, ranging between 0 % and 34.38 %. The regression estimate for age at first calving was 1.72 ± 1.61 days, which indicated that the age at first calving increascd by 1.72 days for each one percent increase in inbreeding. The regression analysis showed a non-significant (P>0.05) effect of inbreeding on age at first calving.

Özet

Bu çalışmada Van Tarım Meslek Lisesi İşletmesinde yetiştirilen İsviçre Esmeri sığırlarda ilkine buzağılama yaşına akrabalı yetişme katsayısının etkileri incelenmiştir. Sürüde ortalama akrabalı yetişme katsayısı % 0 ile % 34.38 arasında değişmiş ve ortalama % 6.88 ± 0.96 olarak bulunmuştur. İlkine buzağılama yaşına akrabalı yetişme katsayısının regresyonu 1.72 ± 1.61 gün olarak bulunmuştur. İlkine buzağılama yaşına akrabalı yetişme katsayısının etkisi önemsiz (P>0.05) bulunmuştur. İlkine buzağılama yaşına akrabalı yetişme katsayısının regresyonu 1.72 ± 1.61 gün olarak bulunmuştur. İIkine buzağılama yaşına akrabalı yetişme katsayısının etkisi önemsiz (P>0.05) bulunmuştur.
