Effects of hybrid Broussonetia papyrifera whole plant powder on growth performance,meat quality,serum biochemical indexes,and intestinal morphology of meat rabbits
摘要
Abstract
The experiment aimed to investigate the effects of replacing a portion of corn,expanded soybean meal,and other ingredients in the basic diet of meat rabbits with hybrid Broussonetia papyrifera whole plant powder on the growth performance,slaughter performance,organ index,meat quality,serum biochemical indexes,and intestinal tissue morphology of meat rabbits.A total of 192 commercial meat rabbits weaned at 35 days of age were randomly divided into four groups,with six replicates per group and eight rabbits per replicate.Some corn,extruded soybean meal,peanut shell,and peanut vine in the basal diet were replaced by 0%(control group),5%(5%group),10%(10%group)and 15%(15%group)hybrid whole plant meal,respectively.The pre-feeding period was seven days,and the formal trial period was 30 days.The results showed that compared with the control group,the 5%group could extremely increase the final weight of the rabbits(P<0.01)and increase the average daily weight gain(P>0.05).The 10%group could extremely increase the daily feed intake and growth rate(P<0.01),and extremely reduce the incidence and mortality rate(P<0.01).All experimental groups extremely reduced liver weight and liver index(P<0.01).The shear force of the longissimus dorsi muscle of rabbits in all experimental groups was extremely higher than that of the control group(P<0.01),with the 10%group being the highest.Compared with the control group,the 10%and 15%groups could extremely reduce the serum albumin/globulin ratio and the urea nitrogen/creatinine ratio,and significantly increase creatinine content(P<0.05).The 15%group could significantly increase the activity of alanine aminotransferase(P<0.05).The 5%group could extremely increase the villus height of the duodenum,jejunum,and ileum(P<0.01),and significantly increase the villus crypt ratio of the duodenum(P<0.05).The 15%group could extremely increase the villus crypt ratio of the ileum(P<0.01).The results show that 5%and 10%hybrid Broussonetia papyrifera whole plant powder has a good effect on improving growth performance,serum biochemical indexes,meat quality and intestinal tissue morphology of meat rabbits.关键词
