Abstract

This study was planned to analyse the reproduction performance and impact of non-genetic factors on reproduction traits in Large White Yorkshire (LWY) pigs maintained in organized breeding farm. Records on 224 breedable female pigs for the periods from 2015 to 2022 were collected from Pig Breeding Unit, PGRIAS, Kattupakkam and utilised for this study. Reproduction traits evaluated in this study were age at first farrowing (AFF), farrowing interval (FI), litter size at birth (LSB), litter weight at birth (LWB), litter size at weaning (LSW) and litter weight at weaning (LWW) and the estimated over all mean values were 464.56 ± 10.09 days, 244.03 ± 4.21 days, 7.685 ± 0.101, 9.967 ± 0.145 kg, 7.488 ± 0.098 and 54.900 ± 0.723 kg respectively. This study concluded that, non-genetic factors like period, season and parity effect all the reproduction traits in the studied LWY pig population

Conclusion

This results provides a key information on influence of non-genetic factors on reproduction traits in LWY pigs. More attention on scientific pig farming practices plays a key role in the improvement on overall performance of pigs. The estimated overall mean of reproduction traits indicates potential of LWY pigs in that population and more care may be taken on management practices to avoid the variation due to non-genetic factors
