发酵玉米芯对海兰褐雏鸡生长性能、血清生化及肠道发育的影响
Effects of fermented corn cobs on growth performance,serum biochemistry,and intestinal development of Hy-Line brown chicks
摘要
Abstract
The experiment aimed to investigate the effects of fermented corn cobs on the growth performance,immune organ index,serum biochemistry,liver biochemistry,and intestinal development of Hy-Line brown chicks.A total of 240 one-day-old Hy-Line brown chicks were randomly divided into five groups,with four replicates per group and 12 chicks per replicate.The control group(group CON)was fed with basal diet,while the experimental groups were supplemented with 2%(group FCC1),4%(group FCC2),6%(group FCC3),and 8%(group FCC4)of fermented corn cobs in the basal diet,respectively.The pre-test period was seven days,and the formal test period was 35 days.The results showed that compared with the group CON,the average daily feed intake in groups FCC2 and FCC3 was significantly increased(P<0.05).The thymus index of group FCC4 was significantly reduced(P<0.05).The serum alanine aminotransferase activity was significantly increased in groups FCC1 and FCC2(P<0.05),while the serum triglyceride content was significantly decreased in group FCC2(P<0.05).The activity of alkaline phosphatase in the liver of group FCC3 was significantly increased(P<0.05).The crypt depth of the jejunal in groups FCC2 and FCC3 was significantly reduced(P<0.05),and the villus height to crypt depth ratio of the jejunum was significantly increased(P<0.05).The villus height of the ileum in the group FCC4 was significantly increased(P<0.05),and the villus height to crypt depth ratio of the ileum in the groups FCC2 and FCC4 was significantly increased(P<0.05).The study shows that supplementing fermented corn cobs to the diet has a positive effect on the growth performance and immune organ index of Hy-Line brown chicks,which can alleviate liver cell damage,promote liver lipid metabolism,bone growth and development,and intestinal morphology development.The appropriate addition amount of fermented corn cobs is 4%.关键词
