Abstract

length in North Sulawesi province. Data on animal live weight (LW), body length (BL) and chest girth(CG) were collected from all cows (n=363) kept by traditional household farmers. Regression analysiswas carried out to estimate LW from all linear body measurements. Data were classified based on age ofanimals consisted of five groups with the first age group of two and half years old, to the fifth age groupof seven and half years old. The results showed that age significantly (P<0.05) influenced all bodymeasurements. Correlations between all pairs of measurements were highly significant (P<0.001) for allage groups. Regression analysis showed that live weight could be predicted accurately from chest girthand body length (R2=0.97). Multiple regression model can be recommended to predict live weight ofOngole grade cows based on those variables with their age groups ranging from 2.5 to ≥7.5 years old asfollows: Live weight (kg) = -806.410 + 4.79835 CG (cm) + 2.83500 BL (cm).

Abstract

The objectives of this study were to detect the Mendelian mode inheritance of growth hormone(GH) and to establish genotype frequency of GH gene in Ongole-crossbred cattle mated by the artificialinsemination (AI) technique. Total of 76 blood samples were collected from Ongole-crossbred cows andbulls (G0), and their progenies (G1) at the Tumaratas AI service center in North Sulawesi province,Indonesia. All blood samples were screened for the presence of GH locus using a PCR-RFLP methodinvolving restricted enzyme Msp1 on 1.2 % of agarose gel. Data were analyzed using statistical programfunction in Excel XP. The results showed that GH locus using alleles of Msp1+ and Msp1- enzymerestriction in Ongole-crossbred cows and bulls was inherited to their Ongole-crossbred progeniesfollowing the Mendelian mode inheritance. This Mendelian inheritance generated by AI technique wasnot under genetic equilibrium for the Msp1 genotype frequencies in groups of G0 and G1. The breedingprogram using genotypes of bulls and cows (G0) for generating the genotype of GH Msp1 enzymerestriction by AI technique should be maintained to increase these various allele dispersion rates forbreeding under genetic equilibrium of the Ongole-crossbred cattle population.

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.
