Effects of Fermented Feed Mulberry Powder on Growth Performance, Meat Quality and Serum Biochemical Indexes of Ningxiang Pigs
摘要
Abstract
This study was aimed to investigate the effects of fermented feed mulberry powder on growth per-formance, meat quality and serum biochemical indexes of Ningxiang pigs. Ninety Ningxiang pigs with average body weight of about 30 kg were randomly divided into 5 groups with 3 replicates(pens)per group and 6 pigs per replicate. Pigs in control group were fed a basal diet,and the others in groupsⅠ,Ⅱ,Ⅲ andⅣ were fed the fermented diets supplemented with 9%, 12% and 15% feed mulberry powder and the unfermented diets supplemented with 9% feed mulberry powder. The trial was divided into 2 stages, 1 to 50 days of earlier growth stage and 51 to 75 days of later growth stage. The results showed as follows: 1)the ratio of feed to gain of Ningxiang pigs in groupⅠwas significantly lower than that in control group and groupⅣfrom 1 to 50 days(P<0.05). 2)Compared with control group, the average backfat thickness of Ningxiang pigs in groupsⅠ, Ⅱ, ⅢandⅣwas significantly decreased(P<0.05). 3)Compared with control group,the content of to-tal cholesterol in serum of Ningxiang pigs in groupsⅠ,Ⅱ,ⅢandⅣwas significantly decreased(P<0.05). The content of total protein in serum of Ningxiang pigs in groupⅠat the 50thday was significantly higher than that in group Ⅳ(P<0.05). In conclusion,feed mulberry powder has better feeding effects after fermented,it is able to reduce average backfat thickness of Ningxiang pigs, improve meat quality and reduce the content of total cholesterol in serum. The fermented diets supplemented with 9% feed mulberry powder can decrease the ratio of feed to gain,and promote the growth performance of Ningxiang pigs.关键词
