Abstract :

A systematic study to record and analyze the reproductive performance of pigs under indigenous and organized systems of rearing is very much essential. Large White Yorkshire (LWY) sows maintained under indigenous and organize systems of rearing in Mizoram were studied for different reproductive parameters. Under the indigenous and organize systems of rearing, the mean age at attainment of puberty in gilts was 275.00�±9.77 and 286.00�±10.50 days, age at first conception was 317.00�±9.01 and 346.00�±15.10 days, length of gestation period was 114.70�±0.11 and 115.00�±0.26 days, the farrowing rate was 91.72 and 90.48 percent, percentage of stillbirth was found to be 3.36 and 4.48, mean litter size at birth (live born piglets) was found to be 9.05�±0.25 and 8.87�±0.23 and mean litter size at weaning was 8.22�±0.26 and 7.39�±0.23, percentage of piglets died prior to weaning was 9.16 and 16.68 percent. The sex ratio of male piglets at birth was found to be 50.04 and 50.05 percent. The mean service period was found to be 69.86�±1.71 and 86.34�±2.37 days. The mean weaning to oestrus interval was found to be 16.87�±1.50 and 27.45�±2.46 days and the farrowing interval was found to be 188.70�±3.99 and 212.90�±3.93 days; respectively. It was found that there was no difference in most of the reproductive performance recorded under the two systems of rearing except in the age of 1st conception, litter size at weaning, pre-weaning piglet mortality, service period, weaning to oestrus interval and farrowing rate where it was significantly higher under indigenous system of rearing.
