| Summary: | The objective of this study was to determine breeding value (BV) of rams
of Garut sheep at Technical Implementation Unit Development Center for Livestock
Breeding Margawati, Garut, West Java. This research was conducted from April
2014 to October 2014. The materials which were used in this study were data record
during the last 5 years (2009–2014) that consists of 55 rams and 579 lambs which
have weaning weight data. Weaning weight data has previously been corrected
based on the type of birth, sex, and weaning age of 100 days. The BV was estimated
using the components of heritability and repeatability value which were previously
analyzed. The heritability and repeatability values of this study were 0.45 ± 0.08
and 0.34 ± 0.09. Estimation of heritability for weaning weight was calculated using
paternal half-sib correlation, and the repeatability was estimated using interclass
correlations method. The breeding value was estimated for the absolute value
(NPabs) of rams based on weaning weight of the progenies. There were top 10 of
dams with the highest BV. The result was sorted by the highest value to the lowest.
The highest BV was 16.37 by the name antasena, and the lowest BV has been
reported for wayang (15.45). The result of this study can be used as the basis recommendation
for selecting rams in Technical Implementation Unit Development
Center for Livestock Breeding in Margawati Garut, West Java.
