Effect of Dietary Probiotics on Growth and Pathological Status in Growing-Finishing Pig
생균제 급여가 비육돈의 발육 및 질병발생에 미치는 영향
Abstract
A study was conducted to determine the effect of dietary probiotics or antibiotics on growth and pathological status in growing-finishing pigs. Ninety male pigs weaned at 24 days of age were divided into three groups of 30 pigs each on the basis of body weight and litter. Three groups of ten pigs(one pen) each were assigned to one of the following diets; a control diet or diets containing 0.1% probiotics or 0.1% antibiotics (1:1 mixture of kitasamycin and sulfamethazine). Average daily gain (ADG), feed efficiency(G/F) and the pathological status were monitored. ADG, feed efficiency and carcass quality were not different (P>0.05) among the three treatments. But pork quality in pigs fed probiotics tended to be improved, compared to other treatments. The pigs fed probiotics had lower pathological lesion in intestinal monitoring than that of other treatments pigs. The chemical composition of slurry(BOD, COD, SS, T-N, T-P and ammonia) in the probiotics treatments tended to be decreased, compared to other treatments. Results of this study suggest that dietary probiotics improve pigs' housing environment, and decrease the contents of polluting materials in slurry.
