Gopinathan, A. | Usha, A.P.
Data on a total of 24 pigs belonging to different genetic groups viz., Large White Yorkshire, Desi and crossbreds were analysed from weaning to eight month of age to study the effect of genetic group on growth and carcass traits. The effect of genetic group was found to be highly significant for third, fifth and eighth month bodyweights in Large White Yorkshire, Desi and crossbred pigs. No significant difference was observed in third month of age between Large White Yorkshire and crossbred pigs. The growth studies indicated that higher body weight and average daily gain were noticed in Large White Yorkshire and followed by crossbred and Desi pigs in all months. Better feed conversion efficiency (2.77 ± 0.10, 3.75 ± 0.26 and 5.03 ± 0.42) was noticed at fifth month in Large White Yorkshire and crossbred pigs and at fourth month in Desi pigs respectively. The different genetic groups differed significantly with respect to dressing percentage, back fat thickness, loin eye area and carcass length. The Large White Yorkshire exceeded the crossbred and Desi pigs in all the carcass traits.
