Reproductive Performance in Large White Yorkshire Crosses

The litter traits of Large White Yorkshire crosses viz. LWY x desi (50% LWY, n= 59) and LWY x 50% LWY (75% LWY, n = 70) in three consecutive generations (F1, F2 and F3) were recorded. The data were analysed on both the genetic groups in three generations for reproductive traits viz. litter size at birth, litter size at weaning, litter weight at birth and litter weight at weaning. The overall mean litter size at birth and weaning were 5.26 ± 0.22 and 4.86 ± 0.20 respectively. The litter size at birth did not vary significantly between F2 and F3 while both differed significantly (P<0.01) with F1.
