Estimates of Genetic and Phenotypic Trends Considering Early and Lifetime Performance Traits in Murrah Buffaloes
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 6
Abstract
Data on 479 Murrah buffaloes over a period of 24 years from 1990 to 2013 related to early and lifetime performance traits were collected from history sheets maintained at Buffalo Research Centre, LUVAS, Hisar. All the early performance traits had positive genetic trends that varied from 14.97±4.95 kg/period, 0.04±0.02 kg/period, 0.03±0.01 kg/period, 0.34±0.68 days/period and 1.83±1.06 days/period for FLMY, FPY, FLMY/FLL, FSP and FCI, respectively. The genetic trends for lifetime performance traits were found to be negative for LTMY, PL and HL traits while it was positive and very low for MY/PL and MY/HL. Positive genetic trends for FLMY, FPY and FLMY/FLL and negative phenotypic trends for FCI and FSP are in desirable direction. Moreover, negative genetic and phenotypic trends for LTMY, PL and HL are suggestive and indicator to streamline the breeding policy for attaining the desired genetic improvement for ameliorating the productive life as well as herd life there by taking care of LTMY.
