Conteúdo: | Multi-trait selection indices in Bharat  Merino sheep were constructed to explore the possibility of selecting ram at an early age without sacrificing net aggregate genetic- economic gain of the index. The data on Bharat Merino sheep evolved at this Institute with 75% Rambouillet/Merino inheritance were used. The population has been undergoing selection and inter se mating since 1982. The records on 556 individuals, sired by 85 rams, were analysed. The genetic and phenotypic variance and covariance components were estimated using LSMLW Programme PC-2 Version (Harvey 1990). Ten selection indices were constructed using3-month body weight(III-WT),6-month body weight (VI-WT), greasy-fleece weight at 6 months of age (GFW 1) andgreasy-fleece weight at 12 months of age (GFW 2) in , different combinations.
