Abstract

The data on 1317 Landrace and 1228 Large White Yorkshire pigs on reproductive traits were analysed by Least Squares Technique. The overall least squares means for LSB, LSW and AGF were observed as 9.48±0.06, 8.13±0.12 and 513.83±4.78 days, respectively in LR pigs. The corresponding values for LWY breed were 9.42±0.06, 7.48±0.08 and 441.67±3.34 days, respectively. The effect of year and sequence of farrowing were observed significant on reproductive traits in both the breeds, whereas, season of farrowing had a non-significant effect. The effect of centers was observed significant on AGF in LWY pigs. The significant increase in litter size was observed from first to subsequent farrowing in LR and LWY pigs.
