金荞麦根粉对山麻蛋鸭产蛋性能、蛋品质、血清抗氧化能力及免疫功能的影响OA

The experiment aimed to investigate the effects of Fagopyrum dibotrys root meal on the laying performance,egg quality,serum antioxidant capacity,and immune function of Shanma laying ducks.A total of 512 healthy 40-week-old Shanma laying ducks with similar laying performance and body weight were randomly divided into four groups,with eight replicates per group and 16 ducks per replicate.The control group(group CON)was fed the basal diet,while the experimental groups were fed the basal diets supplemented with 1%(group G1),2%(group G2)and 3%(group G3)Fagopyrum dibotrys root meal,respectively.The pre-test period was seven days,and the formal test period was 49 days.The results showed that there was no significant difference in laying performance among the groups(P>0.05).Compared with the group CON,the shell strength and yolk color of duck eggs in groups G2 and G3 were significantly increased(P<0.05),and the yolk color in group G1 and shell proportion in group G3 were significantly increased(P<0.05).Compared with the group CON,the serum superoxide dismutase(SOD)activity in group G1 was significantly enhanced(P<0.05).The interleukin-4(IL-4)content in group G2 was significantly increased(P<0.05),while the interleukin-1β(IL-1β)content was significantly reduced(P<0.05).The study shows that dietary supplementation with Fagopyrum dibotrys root meal has no negative impact on laying performance of Shanma laying ducks,and can improve the eggshell quality and yolk color,enhance antioxidant capacity and immune function.The recommended addition amount is 2%.
