Performance of crossbred (Landrace x local Indian) grower pigs on maize replaced wheat bran and deoiled rice bran based diets

Abstract

A study was conducted on 6 groups of8 crossbred piglets in each to spare grain from the diet of pigs. The animals were of about 7 week of age and 6.33±0.14 kg mean body weight. The animals in groups, WL₁, WL₂ and WL) were fed 40,62 and 85% wheat bran based and 0,50 and 100% rhaize replaced diets. Wheat bran of these diets was replaced (W/W) with deoiled rice bran (DORB) in groups, RL" RL2 and RL. Average growth pattern was similar in the animals on wheat bran based diets with comparable average daily feed intake, ADG and feed/gain ratio. On feeding DORB based diets all these responses were adversely affected and therefore DORB fed animals could attain only 16.5 to 26.3 kg body weight by 112th day of feeding in comparison to 35.24 to 37.15 kg in wheat bran based diets after 105 day of feeding. The overall digestibility of organic nutrients, except for CF, was significantly (P<0.01) higher in wheat bran based diets than DORB based diets with the marginal difference in CP digestibility. It can, thus, be concluded that crossbred grower pigs can be fed on low grain or gainless wheat bran based diet, but not on deoiled rice bran incorporated diet, without adversity affecting growth and nutrient utilization.
