Abstract

The heritability, estimated breeding value and correlation are the important genetic parameter that determines genetic improvement in animal. The aim of this research was to discover the heritability, breeding value and phenotypic correlation for quantitative traits in one day old Indonesian sheep. This research was conducted from 7th August to 7th December 2022 in PT Juara Agroniaga Sejahtera, Bojonegoro, East Java. The materials used were 72 heads of Indonesian sheep at one day of age, offspring of 6 sires and 28 dams. The research used was quantitative method with direct observation in the field. The variables observed were birth weight (BW) and morphometric traits (chest girth (CG), upper neck circumference (UNC), and lower neck circumference (LNC)). Heritability value was estimated using paternal half-sib correlation method and the variance components were analysed using the Analysis of Variance (ANOVA) single factor. Estimation of breeding values were calculated using the performance of progeny. The result showed that mean of BW, CG, UNC, and LNC for single birth were 2.78±0.74 kg, 32.07±3.56 cm, 15.71±1.38 cm, 17.71±1.38 cm; for twin birth were 1.78±0.48 kg, 27.27±2.70 cm, 13.96±1.38 cm, 17.71±1.38 cm; for triplet birth were 1.35±0.38 kg, 24.23±2.64 cm, 12.60±1.30 cm, 14.03±1.46 cm; for quadruplet birth were 1.06±0.22 kg, 22.63±2.39 cm, 12.06±1.15 cm, 13.94±1.02 cm. Heritability value for BW, CG, UNC, and LNC were 0.64±0.03; 0.62±0.03; 0.87±0.18; 0.43±0.12 respectively. The correlation of CG, UNC and LNC with BW were high positive values (0.86, 0.82 and 0.92, respectively). The body weight is the important selection criterion to improve the production trait due to its high heritability value. However, if the weighing scales are not available, selection could be based on the morphometric trait. LNC is recommended as selection criterion due to its highest correlation with body weight.
