Pendugaan Parameter Genetik Sifat Pertumbuhan Sapi Bali di BPTU HPT Denpasar
Abstract: Breeding Center of
Bali Cattle in Bali has applied Village Breeding Center (VBC) Program which an area
of farmer belonging to groups that develop breeding program. These farms are
expected to act as nuclei in open nucleus schemes, where superior animals are
multiplied at Breeding Center (nucleus), distributed to farmers, andthe best
animals from the farmers are brought back to the central farm for further
breeding. This study was to estimate non-genetic and genetic of growth traits
consisting of birth (BW), weaning (WW), and 12 months (YW) weight. This study
used pedegree record of Breeding Center from 2008 to 2013 years. The number of
sapi Bali used to determine growth traits of BW, WW, and YW were 573; 541; and
523 heads, respectively.Data were analyzed using General Linier Model (GLM) to
identify non-genetic. Estimation of genetic including heritability,
repeatability, genetic and phenotypic correlation were calculated using General
Linier Model and Restricted Maximum Likelihood. Genetic and phenotypic trends
were calculated using the regression mean breeding values on birth
year.Heritability values were 0.02±0.08; 0.83±0.18 and 0.62±0.30for BW, WW and
YW, respectively. The higest correlation showed between WW and YW for genetic
and fenotipic were 0.719 and 0.650, respectively. The regression estimates on
various trends of EBV and phenotipic trends for WW and YW showed no deinite
trendsince the regression equation was not signiicant (P>0.01) and R2 was
relatively low, but the phenotypic trends of BW showed constant decrease
(P<0.01). The results obtained in the present study realized that one signaling
