 ABSTRACT

The present investigation entitled, “Genetic gain in productive and non productive traits through selection indices in HF xGir halfbreds” undertaken to asses the magnitude of different factors along with generations affecting the reproductive and productive traits. The data pertaining to HF x Gir halfbreds maintained from year 1972 to 2016 at RCDP on cattle, M.P.K.V., Rahuri were used for present investigation.
In HF x Gir halfbred cows the heritability of AFC, SP, PMY, LMY, LL, DP< CI, MY/CI, MY/LL was 0.521 ± 0.517, 0.132 ± 0.104, 0.432 ± 0.433, 0.259 ± 0.227, 0.330 ± 0.031, 0.430 ± 0.430, 0.087 ± 0.066, 0.077 ± 0.060 and 0.056 ± 0.061, respectively.
Out of 28 selection indices constructed for HF x Gir halfbreds, index I24to I28 from four traits combination were found to be relatively efficient indices and rated as the most useful indices for their high reliability and expected genetic gain.
