Genetic and Phenotypic Parameter Estimates For Birth Weight in Holstein Cattle Raised At Kahramanmaras State Farm


1 Yrd. Doç. Dr., Kahramanmaraş Sütçü İmam Üniv. Ziraat Fak. Zootekni Böl. 46200 - Kahramanmaras /TÜRKİYE - The purpose of this study is to estimates genetic and phenotpyic parameters for birth weight in Holstein cattie raised at Kahramanmaras State Farm.

The least squares means of birth weight were 29.90 ± 0.90 kg.

Birth number, year and sex had a non-significant effect on birth weight.

Heritability and repeatability estimates for birth weight were 0.07 ± 0.02 and 0.36 ± 0.05. Keywords : Holstein, calf, birth weight, heritability, repeatability
