PENGARUH KETINGGIAN TEMPAT DAN SISTEM PEMELIHARAAN TERHADAP KORELASI GENETIK BOBOT LAHIR DENGAN BOBOT DEWASA SAPI BALI
Abstract: A research has been
done to estimate the genetic correlation between birth weight and parental body
weight of bali cattle with survey method by procedures observation,
measurements, and interviews in highland (Kabupaten Timor Tengah Selatan) and
lowland (Kabupaten Kupang) at difference care system (semi intensive and
extensive). Four hundred eighty bali cattle were use in this research. The
results showed that no significance differences (P>0.05) on sire and dam
body weight based on altitudes, care system, and interaction between altitudes
and care system. However, the birth weight had significant differences
(P<0.05) whereas in highland at semi intensive care system the value was
better than extensive system. Estimation of the phenotype correlation between
birth weight and parental body weight at semi intensive care system showed a
high positive value whether in highland or in lowland for all estimation
components. While for extensive care system, the estimation based on sire
component produced a negative value. The phenotype correlation values based on
dam component was better than sire or sire-dam components. The genetik
correlation values for semi intensive care system showed a positive value, on
the other hand a negative value was found in extensive care system.
