Abstract

In this research, heritability and repeatability of service period (SP), calving interval (CI), gestation length
(GL), number of insemination per conception (NIPC), first service age (FSA), first calving age (FCA), lactation milk
yield (LMY) and lactation length (LL) were estimated using reproductive and productive records in Brown Swiss
herd reared at the Konuklar State Farm in Konya.
The heritability values for SP, CI, GL, NIPC, FSA, FCA, LMY and LL were 0.074 ± 0.096, 0.131 ± 0.146, 0.053
± 0.046, 0.331 ± 0.122, 0.766 ± 0.242, 0.214 ± 0.201, 0.107 ± 0.119, and 0.226 ± 0.156 respectively. The repeatability
values of CP, CI, GL, NIPC, LMY and LL were determined as 0.089 ± 0.071, 0.103 ± 0.101, 0.151 ± 0.059, 0.143
± 0.047, 0.188 ± 0.085 and 0.231 ± 0.084 respectively.

Konuklar Tarım İşletmesinde Yetiştirilen Esmer Sığırların Bazı Verim Özelliklerinin Fenotipik ve Genetik Parametreleri II. Genetik Parametreleri

Abstract

Arastirmada Konuklar Tarim Isletmesinde yetistirilen Esmer sigirlara ait döl ve süt verim kayitlarindan Servis
Periyodu (SP), Buzagilama Araligi (BA), Gebelik Süresi (GS), Gebelik Basina Tohumlama Sayisi (GBTS), Ilk Damizlikta
Kullanma Yasi (IDKY), Ilk Buzagilama Yasi (IBY), Laktasyon Süt Verimi (LSV) ve Laktasyon Süresine (LS) ait
Kalitim ve Tekrarlanma derecesi degerleri hesaplanmistir.
Arastirmada elde edilen kalitim derecesi degerleri SP, BA, GS, GBTS, IDKY, IBY, LSV ve LS için sirayla 0.074
± 0.096, 0.131 ± 0.146, 0.053 ± 0.046, 0.331 ± 0.122, 0.766 ± 0.242, 0.214 ± 0.201, 0.107 ± 0.119, ve 0.226 ± 0.156
olarak bulunmustur. Bu özelliklerden SP, BA, GS, GBTS, SV ve LS için hesaplanan tekrarlanma derecesi degerleri
ise ayni sirayla 0.089 ± 0.071, 0.103 ± 0.101, 0.151 ± 0.059, , 0.143 ± 0.047, 0.188 ± 0.085 ve 0.231 ± 0.084 olarak
tespit edilmistir.
