Effect of Diets on Growth and Reproductive Performances of Growing Pigs Maintained at Farmer’s Door

Abstract

Aims: This study was conducted to study the effect of different types of diets on growth and reproductive performances of pigs under village managemental conditions Chandel, Manipur.
 Place and Duration of Study: The study was conducted at Krishi Vigyan Kendra, Chandel, ICAR, Manipur Centre between May 2016 to November 2017.
 Methods: The present study was carried out on 36 Hampshire crossbred pigs maintained by 12 farm women of Chandel district of Manipur. Each farm women were provided with 3 weaned piglets having 2 females and one male of about 3 months old. Out of which, the 50% (6 family) farm women were maintained their piglets on 40% wheat bran and 60 % rice fermented waste (D1), whereas pigs of rest 50% (6 family) farm women were maintained on 30 % crushed maize, 30 % rice bran and 40 % rice fermented waste (D2). The different parameters like body weight at different stage, age at sexual maturity, age at first farrowing, litter size at birth and litter size at weans were determined.
 Results: Analysis of variance showed non-significant influence of diets on weight at various ages. The average initial body weight of piglets mentioned on D1 and D2 diets were 16.86 ± 0.25 and 16.75 ± 0.43 kg, respectively which was increased to 52.17 ± 1.86 and 53.56 ± 0.92 kg within three months of experimental period. Sex had significant influence on weight at 4th and 5th months of age. However, males were heavier than females at all the ages under study, the value at 6 months of age were 54.50 ± 1.66 and 52.04 ± 1.30 kg for males and females, respectively. Influence of diet was found to be non-significant on various reproductive traits. The age at sexual maturity, age at first farrowing, litter size at birth and at weaning were found to by 8.45 ± 0.23 and 8.23 ± 0.25 months, 12.95 ± 0.33 and 12.66 ± 0.30 months, 7.58 ± 0.31 and 7.75 ± 0.63 and 7.17 ± 0.13 and 7.42 ± 0.29 in D1 and D2 diets, respectively.
 Conclusion: The results indicated that the rice fermented waste may be incorporated in pig grower ration upto 60 % level without any adverse effect on their growth and reproductive performance to cut down the cost on pig feed.
