Pendugaan Nilai Heritabilitas Bobot Lahir dan Bobot Sapih Domba Garut Tipe Laga
Abstract: The objective of
this study was to estimate heritability of birth and weaning weights of the
fighting type of Garut sheep. The data of birth and weaning weight of 175 SR
(Super lambs, i.e. cross between fighting type Garut rams and selected Garut
ewes) and 61 SB (Sukabumi lambs, i.e. cross between fighting type Garut rams
and Sukabumi ewes) were used. The data were collected from March 2001 to August
2002. The results showed that the means of all traits of SR sheep group were
larger (P < 0.01) than those of SB sheep group. Estimated heritability of
birth weight and weaning weight of SR sheep were 0.67 ± 0.19 and 0.95 ± 0.16 respectively. Estimated heritability
value of birth and weaning weight of SB sheep were 0.53 ± 0.33 and 0.57 ± 0.37 respectively. The heritability of
birth and weaning weight were considered as high which means that the selection
programme will be more effective and efficient in improving the genetic merits.
