Abstract
The present study was carried out in 1025 piglets belonging to two genetic groups viz. Hampshire crossbred and crossbred of Tamworth and Desi (TND) pigs that were being bred and maintained at the Regional Pig Breeding Farm, Kyrdemkulai, Meghalaya. Performance records of 379 and 646 piglets born to 136 gilts/dams and 25 sires belonging to the two genetic groups during the year 2016-2019 were studied with a view to assess the genetic and phenotypic parameters of growth traits viz. body weights at different ages and daily body weight gains during pre-weaning and post-weaning periods.
The overall least-squares means for body weight(kg) at birth, 4th week, 8th week, 12th week, 16th week, 20th week and 24th week of age were found to be 1.247±0.007, 5.615±0.013, 11.302±0.032, 17.246±0.029, 23.349±0.053, 30.584±0.064 and 38.528±0.057 respectively.
