Korelasi Genetik Pada Sifat Pertumbuhan Sapi Aceh di Kecamatan Indrapuri Provinsi Aceh
ABSTRACT: This research was
conducted to estimate genetic correlation of growth traits on Aceh cattle
including birth weight (BW), weaning weight (WW), yearling weight (YW), and
Average Daily Gain (ADG). The research was done at Indrapuri Breeding and
Forage Centre (IBFC) of Aceh cattle from March 2013 to April 2013. The
materials of this research consist of growth records from 2010 to 2012. The
genetic correlation was analyzed by variance and covariance. The results
indicated that the lowest standard error (SE) value of heritability showed on
birth weight 0.15+0.13. Most of genetic correlation value on growth traits was
positive and high categorized (> 0.50). The lowest SE value showed on
correlation between birth weight and pre-weaning ADG (0.55+0.54), birth weight
and post-weaning ADG (0,63+0,62), pre-weaning ADG and post-weaning ADG
(0.71+0.33), pos-weaning ADG and weight/age or W/A (0.72+0.33) then final
weight and W/A (0.94+0.69). It could be concluded that most of genetic
correlation value on Aceh cattle growth traits were positive and high therefore
the selection based on growth traits can be done for increasing performance in
Aceh cattle.
