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.
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.
