HERITABILITIES OF BODY SIZE BY GROWTH HORMONE (GH-Msp1) GENOTYPES USING PCR-RFLP IN ONGOLE GRADE CATTLE
Abstract: Genotypic
performance in term of heritability as the crucial factor of animal economical
traits for body size inheritance had not been fully studied in Ongole-grade
cattle. The objectives of this research were to define the heritability values
of live weight, chest girth and body length in Ongole-crossbred cattle. Total
of 37 blood samples were collected from parental cows and 2 blood samples from
parental Ongole breed bulls. All blood samples were screened for the presence
of growth hormone (GH) locus using PCR-RFLP method involving restricted enzyme
Msp1 on agarose-gel (1.2%). Data were analyzed using statistical program in
Excel XP. Results showed that the phenotypic estimation average of Ongole grade
cattle population of live weight, chest girth and body length were 445.41 ±
45.95 kg, 175.35 ± 4.11 cm, and 139.70 ± 5.73cm, respectively. The heritability
values of animal live weight, chest girth and body length in this study were
0.24, 0.003, and 0.41, respectively. These heritability values of animal live
weight and body length would be categorized as moderate to high genotypic
performance values, while the heritability of animal chest girth was included
in low heritability standard of the animal economical trait performance.
