Effects of Dietary Inclusion Levels of High-Moisture Corn on Growth Performance,Serum Biochemistry Indices and Intestinal Microbiota in Cherry Valley Ducks
摘要
Abstract
This experiment was conducted to investigate the effects of dietary high-moisture corn inclusion levels on growth performance,serum biochemical indices,meat quality,antioxidant capacity,and intestinal development of Cherry Valley ducks under net-rearing conditions.A total of 5 040 15-day-old healthy Cherry Valley ducks were selected and randomly divided into six treatment groups using a single-factor ran-domized design,with dietary high-moisture corn addition levels of 0(control group),5%,10%,15%,20%,and 25%,respectively.Each group had seven replicates,and the ducks were raised to 42 days of age,with relevant indices determined and analyzed.The results showed that:① In terms of growth performance,there were no signifi-cant differences in average daily gain(ADG)and feed-to-gain ratio(F/G)between the 5%and 10%groups and the control group(P>0.05);however,ADG was significantly decreased(P<0.05)and F/G was signifi-cantly increased(P<0.05)in the 15%,20%,and 25%groups.② The leg muscle pH in the 10%and 25%groups was significantly decreased(P<0.05),but there was no significant change in amino acid composition(P>0.05).③ Compared with the control group,the globulin(GLB)level was significantly increased in the 10%,15%,and 25%groups(P<0.05),and the total protein(TP)level was significantly elevated in the 15%and 25%groups(P<0.05);whereas the glutathione peroxidase(GSH-Px)activity was significantly reduced in the 10%-25%groups(P<0.05).④ 16S sequencing results indicated that dietary high-moisture corn sig-nificantly decreased the abundance of Firmicutes(P<0.05)and significantly increased the abundances of Bacteroidetes and Actinobacteriota in the cecum(P<0.05);compared to the control group,the Shannon index was significantly increased in the 5%,10%,20%,and 25%groups(P<0.05),and the ACE index and Chao1 index were significantly improved in the 5%and 10%groups(P<0.05).⑤ Regarding economic ben-efit indices,the cost-to-meat ratio was significantly reduced in the 10%,20%,and 25%groups(P<0.05),with the 10%group showing the lowest leg muscle cost-to-meat ratio.In conclusion,adding 5%and 10%high-moisture corn to the diet of Cherry Valley ducks can optimize the cost-to-meat ratio without affecting growth performance,and significantly improve intestinal microbiota diversity.关键词
