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, feed conversion efficiency and cost of production per kg of live weight
gain from weaning to eight months of age. The growth studies indicate that higher body weight
was noticed in Large White Yorkshire 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 best feed conversion efficiency value was observed as 1:4.8 in Large White Yorkshire pigs,
followed by 1:5.1 in crossbred pigs and 1:5.9 in Desi pigs. The production cost per kg of live
body weight gain in Large White Yorkshire, crossbred and Desi pigs was found to be Rs. 47.04,
Rs. 49.15 and Rs. 56.85 respectively from weaning to eight months of age.
