Abstract

This study was carried out to investigate the effects of beginning to fattening weight and season on some fattening traits, and some slaughter characteristics of Holstein young bulls in intensive conditions. The 1661 Hol-stein young bulls used in the study were grouped according to their beginning to fattening weights (176-225 kg, 226-275 kg, 276-325 kg and 326-400 kg) and the season in which the fattening began. The effects of the factors investigated were determined by the use of general linear model (GLM) procedure in SPSS program package. In the study, the groups having lower beginning to fattening weights gained higher live weights during the 210 days of fattening. As a result of the seasonal temperatures, the fattening performances of the Holstein young bulls were the lowest in summer, while being the highest in autumn. The dressing percentage of Holstein young bulls was 57.8% and the effect of slaughter weight was not significant on dressing percentage.

Özet

Bu çalışma, entansif koşullarda Siyah Alaca danaların bazı besi özellikleri üzerine, besi başlangıç ağırlığı ve mevsimin etkilerinin incelenmesi ve bazı kesim özelliklerinin belirlenmesi amacıyla yapılmıştır. Çalışmada kullanılan 1661 Siyah Alaca dana, besi başlangjç ağırlığına (176-225 kg, 226-275 kg, 276-325 kg ve 326-400 kg) ve besiye başlanılan mevsime göre gruplandırılmıştır. İncelenen faktörlerin etkisi SPSS program paketinden GLM prosedürü kullanılarak belirlenmiştir. Çalışmada, 210 günlük beside daha düşük canlı ağırlıkta besiye başlayan gruplar daha fazla canlı ağırlık artışı sağlamışlardır. Besi dönemi yaz aylarına rastlayan Siyah Alaca danaların besi performansları yüksek çevre ısısı nedeniyle daha düşük düzeylerde, sonbaharda besiye alınan danaların besi özellikleri ise daha yüksek düzeylerde belirlenmiştir. Siyah Alaca danaların karkas randımanı %57,8 olarak elde edilmiş ve kesim ağırlığının karkas randımanı üzerine etkisi önemsiz bulunmuştur.
