USING LIQUID FERMENTED FEEDS FOR COMMERCIAL MONG CAI PIGS

Abstract

The experiment was conducted on 90 male Mong Cai pigs in the post-weaning stage at the Thien Thuan Tuong Company, Cam Pha, Quang Ninh. Experimental were divided into 3 experimental groups, each with 30 pigs. Pigs in each group were raised in 3 cages (3 time replication). Pig in group 1 eat commercial feed, pigs in group 2 eat liquid fermented feed using 20% ​​agricultural by-products in the diet, pigs in group 3 eat liquid fermented feed using 25% agricultural by-products in the diet. Research parameters include: pig weight and weight gain, feed intake, feed efficiency and feed cost for 1 kg of weight gain, productivity and quality of pork. Experimental results showed that the weight gain of pigs in both growing and fattening stages with commercial industrial feed was higher than that of pigs fed with liquid fermented feed using agricultural by-products. The feed consumption per 1 kg of weight gain of pigs fed on liquid fermented feed using agricultural by-products was significantly higher than the group of pigs fed commercial industrial feed. The feed cost for 1 kg of weight gain of pigs using liquid fermented feed is lower than the group of pigs using commercial industrial feed. The use of liquid fermented feed using agricultural by-products does not affect on productivity and meat quality except of carcass volume. Using 20% ​​agricultural by-products in the diet gives higher livestock efficiency than using 25% agricultural by-products in the diet.
