Abstract

This study was conducted to estimate breeding values of 232 Simmental cows for 305-day milk yield calved between 1990 to 2000. Breeding values were obtained for animals by using individual animal model. Although, phenotypic values of 305 day milk yield showed a smooth increasing trend in the examined period, genetic trend has not shown a substantial trend among the years, generally an irregular fluctuation was observed. It is concluded that there was not any standard selection programme in the evaluated Simmental herd reared in Kazova state farm.

Özet

Araştırmada, Kazova Tarım İşletmesinde yetiştiriciliği yapılan ve 1990-2000 yılları arasında buzağılayan 232 Simmental ineğin 305-gün süt verimi bakımından damızlık değeri tahmin edilmiştir. Hayvanlara ait damızlık değerleri bireysel hayvan modeli ile tahmin edilmiştir. 305-gün süt verimine ait fenotipik değerler düz bir artış eğiliminde olmasına rağmen, genetik yönelim yıllar arasında dalgalı bir seyir takip etmiştir. Sonuç olarak, Kazova Tarım İşletmesinde yetiştirilen Simmental ırkı sığırlar için standart bir seleksiyon programı uygulanmadığı anlaşılmaktadır
