ABSTRACT

The meat industry in India is fast developing and pig is an ideal meat animal under Indian conditions. If preweaning growth in piglets are achieved optimum it will reduce the economic loss and will be helpful in quick economic return. Growth and mortility study was undertaken on 186 piglets born to twenty four deshi, 50 per cent and 75 per cent large white yorkshire sows upto weaning. Heaviest litter weight of 7195.57 g was recorded in 75 per cent pigs with 7.7 litter, followed by 6223.30 g with 8.1 litter in 50 per cent and 3125.81 g with 5.5. litter in deshi pigs. Their individual birth weights were estimated as 934 g, 824 g and 568 gin 75 per cent, 50 percent and deshi piglets respectively and their birth weights were statistically significant up to three weeks of life. Weight gain was maximum in 75 per cent piglets, but after 4th week till weaning the highest weekly weight gain was recorded in half bred piglets. Analysis of variance. showed a significant and difference between the breed season and bread season interaction except in 3rd and 4th week. Overall 12.90 per cent mortality in piglets were recorded with higher rate of mortality up to second week. Later on in subsequent week mortlity decreased rapidly in all the blood groups. Maximum percentage of mortality was recorded in three fourth piglets followed by. halfbred and least in deshi piglets. However analysis of variance showed no significant breed differences
