Aggregation of Estimated Breeding Values for Different Traits of Goat

Abstract

The present study was conducted with a view to know the productive and reproductive performances and to estimate the heritability and breeding value of the traits for individual goat in backyard goat flock from three villages in Pirojpur district. Data were collected on regular basis from January to March, 2015 and analyzed by PROC GLM of SAS and Animal Model to know the phenotypic performance and BLUP breeding values of different traits, respectively. The result showed that service per conception and kid number was significantly affected by parity of dam and use of proper breeding system and feeding management. Daily milk production was significantly affected by the type of breeds, body weight and parity of dam. The heritability value of service per conception, number of kid, milk yield, and live weight of goat was 0.204±0.364, 0.017±0.623, 0.340±0.381, and 0.269±0.402, respectively. The estimated breeding values of service per conception, number of kid, milk yield and live weight of dam were ranged from -0.38 to 0.47, -0.14 to 0.60, -0.30 to 0.78, and 0.73 to 0.34, respectively. Estimated breeding values of individual were aggregated and ranking was performed. If the proper breeding and scientific management could be ensured to the village goat flock it will be profitable.
