- Abstract
The study was carried out on the data of pigs breeding farm spread over a period of 20 years from 1982 to 2001 belonging to three genetic groups viz. Landrace, Desi (local-non descript) and their half breeds maintained and it was found that Genetic group had significant effect on the mortality particularly up to 1st two weeks of ages and non-significant thereafter up to 8th weeks of ages. Significantly highest mortality was observed in Landrance than LR × D and desi(local-non descript) during first two weeks. The whole data were grouped in to 4 season on the basis of climatological data viz.,winter (December to February-cold),summer (March to May- dryhot), Rainy (Jun to August-hot humid)and autumn (September to Novembermoderate) and the Seasons of farrowing had significant influence on piglets mortality during 0-1, 1-2, 0-2 and 0-8 week of age, but it had non-significant influence during 2-8 weeks of age. The season should have in fact its effect on newly born piglets upto 2nd week of age as seen in present study. Parity had nonsignificant influence on pre-weaning mortality rate in present study.
