In order to conduct the comparison of pig raising under different raising modes,a total of 40 pigs with the weights of 20- 30 kg were randomly divided into two groups( experimental group,fermentation bed; control group,cement ground). During a 81-day-test,pigs in the two groups were fed with same diets,and growth performance of pigs was compared. After the feeding,six pigs of each group were slaughtered in order to examine meat quality. The results showed that average daily gain of pigs in test group was 17. 93% higher than that in control group,difference between the two groups was significant. Feed weight ratio of pigs in test group was 14. 73% lower than that in control group,difference between the two groups was not significant. Color,water loss,drip loss,intramuscular fat,etc. of meat in test group were all better than that in control group,difference of drip loss between the two groups was extremely significant,while differences of color,water loss and intramuscular fat( IMF) between the two groups were not different. Pig raising by bio-bed system could improve growth performance and pork quality comparing with cement ground system.
