Genetic Parameters of Growth and sow Productivity Traits of Large white Yorkshire with Desi and Tamworth with Desi Crossbred Pigs
Abstract: <div>The present study was conducted to estimate genetic parameters like heritability, genetic and phenotypic correlations among different growth and reproductive traits of LWY x Desi and TMW x Desi maintained at AICRP on Pigs, Livestock Farm, Adhartal, Jabalpur (M.P.). The h2 estimates for birth weight for LWY and TMW crossbreds has been recorded as 0.011±0.075 and 0.012±0.079 respectively and for weaning weight it has been recorded as 0.271±0.117 and 0.282±0.116 respectively for LWY and TMW crossbreds. The h2 estimates of body weight at different ages had low to moderate and some where higher at different age. The genetic correlation values at birth were ranged from 0.19 to 0.73 and 0.16 to 0.71 for LWY and TMW crossbreds respectively. The h2 estimates for maternal traits of LWY and TMW crossbred pigs are within the specified range. Most of the</div><div>genetic and phenotypic correlations are at higher side with positive direction.</div><div>Environmental correlations also followed the same trend where most of the values are higher for Large White Yorkshire and Tamworth crossbred Pigs.</div>
