EFFECT OF CLIMATE ON LITTER TRAITS OF CROSSBRED PIGS IN MIZORAM
86 / 25
Abstract
ABSTRACT
A study on seasonal effect of climate on the litter traits of cross bred pigs was
undertaken in different districts of Mizoram such as Aizawl, Lunglei, Champhai and Kolasib.
Data of 11 years i.e. January 2002 to December 2012 was collected from a total of 11,376
animals. Meteorological data was also collected from MIRSAC. The average litter size at birth
ranges from 6.469±0.15 to 6.853±0.15 and litter weight from 7.100±0.20 to 7.843±0.19 kg.
However, there was non-significant difference between litter traits at the time of piglet birth in
different seasons. However, at the time of weaning, average litter size ranges from
5.484±0.14 to 5.995±0.14 and litter weight ranges from 49.92±1.28 to 55.27±1.20 kg. There
was significant differences in litter size at weaning (P<0.05) as well as litter weight at
weaning (P<0.01). This indicates that season has significant effect on litter traits at the time
of weaning.
Key Words : Season, litter traits, performance, cross-bred pigs.
