PurposeTo study the effect of adding Chinese herbal medicines to the feed on the body weight, egg laying performance, egg quality and leukemia virus suppression of leukemia-positive Wuding chickens.
MethodTwo hundred 90-day-old leukemia-positive Wuding hens were selected and randomly divided into 4 groups, each group was fed a different diet, and the test period was 90 days. With 30 days as the time node, the body weight, egg production performance and egg quality of the chickens were tested, and finally the inhibition of leukemia virus was detected.
ResultsDuring the test period, compared with the basic diet group, the body weight of the 3 test groups at 180 days were significantly increased (P<0.05), and the group 3 was significantly increased (P<0.01); the egg production rate were significantly increased (P<0.05), the ratio of feed-to-egg were significantly decreased (P<0.05), and the group 2 was the most significant; the detection rate of egg virus was significantly reduced (P<0.01), and the group 3 was the lowest; the egg specific gravity, egg yellow color and egg yolk ratio increased significantly (P<0.05), and the highest in the group 2; the survival rates of the three test groups were significantly increased (P<0.01), tumor detection rate is extremely significantly reduced (P<0.01).
ConclusionThe compound Chinese herbal medicine feed additive of the group 2 can improve egg production performance and egg quality, and the third group can improve the suppression of leukemia virus.
