Effects of Alginate Oligosaccharide on Growth Performance,Immune Performance,Serum Antioxidant Capacity and Intestinal Development in Cherry Valley Ducks
摘要
Abstract
This study aimed to investigate the effects of dietary supplementation with Alginate Oligo-saccharides(AOS)on the growth performance,immune performance,serum antioxidant capacity,and in-testinal development of meat ducks.A total of 480 healthy one-day-old Cherry Valley ducks(half male and half female)were randomly assigned to four groups,each with six replicates of 20 ducks.The control group received a basal diet without AOS,while the experimental groups were supplemented with 100 mg/kg,200 mg/kg,and 400 mg/kg AOS in the basal diet.The trial lasted for 42 days.At the end of the ex-periment,body weight was measured to calculate growth performance parameters.Immune indices and se-rum antioxidant markers were measured,and tissue samples from duodenal,jejunal,and ileal were col-lected to prepare paraffin sections.The results showed that compared with the control group,supplemen-tation with 200 mg/kg and 400 mg/kg AOS significantly reduced the feed-to-gain ratio(F/G)during both the 22-42 d period and the entire 1-42 d period,while 200 mg/kg AOS significantly increased the average daily gain(ADG)during the full 1-42 d phase(P＜0.05).Ducks in the 200 mg/kg and 400 mg/kg groups exhibited significantly higher thymus indices,increased serum levels of IgA and IgG,and elevated anti-in-flammatory cytokines(IL-10 and TGF-β),along with significantly reduced levels of the pro-inflammatory cytokine IL-1β at 42 d(P＜0.05).The addition of 200 mg/kg AOS significantly increased the serum super-oxide dismutase(SOD)activity,while 100 mg/kg,200 mg/kg,and 400 mg/kg AOS significantly reduced the serum malondialdehyde(MDA)levels at day 42(P＜0.05).Furthermore,200 mg/kg and 400 mg/kg groups significantly increased the weights of duodenum and jejunum,as well as the villus height in the je-junum and ileum at day 42.Additionally,all AOS-supplemented groups had significantly decreased crypt depth in the ileum at day 42(P＜0.05).In conclusion,dietary supplementation with 200 mg/kg AOS ef-fectively enhances growth performance,immune performance,blood antioxidant capacity,and intestinal development in Cherry Valley ducks,suggesting its potential as a functional feed additive in duck produc-tion.关键词
