The Genetic Parameters for Average Daily Gain and Kleiber Ratio in Charolaise Breed

Abstract

The objective of this paper was to estimate the genetic parameters for average daily gain from 200 days to 365 days and Kleiber ratio in Charolaise breed with maternal animal model. The data were represented by 582 records of Charolaise cattle breed. The pedigree consisted in 1284 cattle: 123 sire, 579 dams and 582 cattle with performances. The data were obtained from Romanian Breeding Association for beef cattle. The direct breeding value of cattle were from -0.339 to 0.969 kg for average daily gain between 200 days and 365 days and maternal breeding value between -0.361 to 0.207. The direct breeding value of cattle for Kleiber ratio were between -0.318 and 0.678 and maternal breeding value between -0.354 and 0.205. The direct heritability for average daily gain from 200 days to 365 days was 0.570, the maternal heritability 0.183 and the total heritability 0.353. The direct heritability for Kleiber ratio was 0.414, the maternal heritability 0.201 and total heritability 0.189.
