Genetic Parameters of Growth Traits in Southern Thai Native Cattle under Management of Thepa Livestock Breeding Station, Songkhla Province

Abstract

The objective of this study was to determine genetic parameters of growth traits in southern Thai native cattle under management of Thepa livestock breeding station, Songkhla Province. The recorded of growth performance were 1,780, during 2002-2013, namely, birth weight (BW), weaning weight (average of age 200 days; W200), average daily gain of weaning weight (ADG200), yearling weight (average of age 400 days; Y400) and average daily gain of yearling weight (ADG400). Data were analyzed then, the result presented average of BW was 14.45 kilogram, W200 was 74.65 kilogram, ADG200 was 243.67 gram per day, Y400 was 95.67 kilogram and ADG400 was 203.80 gram per day. The results of genetic parameters showed that additive direct heritability had ranged 0.17-0.21, maternal heritability had ranged 0.15-0.16 and maternal permanent environmental effect had ranged 0.01-0.04 for growth traits.
