Effect of dietary supplementation of Ligustrum lucidum on performance, egg quality and blood biochemical parameters of Hy-Line Brown hens during the late laying period.

The fruit of Ligustrum lucidum (FLL, Nuzhenzi in Chinese) is an important traditional medicine, and have attracted significant research attention because of their various biological activities. However, there are few research reports available on the use of FLL as a feed additive in livestock nutrition, particularly in layers. This study was conducted to determine the effects of supplementation of the diet of laying hens with FLL on laying performance, egg quality and blood metabolites. A total of 360 72-week-old hens were allocated to three dietary treatments (eight replications of 15 hens/treatment group) and were fed either a control diet or a diet supplemented with an inclusion level of 0.25% or 0.50% of FLL powder in the final feed, until 78 weeks of age. Hens were housed in a three-tier cage system. Feed and water were provided ad libitum. Blood samples and eggs were collected at the end of the experiment. The results showed that dietary supplementation with FLL did not affect egg weight, feed conversion ratio, eggshell thickness, albumen height, egg yolk color, eggshell breaking strength or egg shape index. However, FLL supplementation significantly decreased (P<0.001) mortality, cracked-egg rate and blood serum levels of cholesterol, low-density lipoprotein cholesterol, triglycerides and alanine aminotransferase, and increased (P<0.001) blood serum levels of high-density lipoprotein cholesterol. No differences in serum levels of total protein, albumin, glucose, calcium, aspartate aminotransferase or alkaline phosphatase were observed in hens fed FLL compared with the control group. It can be concluded that FLL, at a supplementation level of 0.25% final feed, can be used as an effective feed additive to improve the performance of laying hens during the late laying period.

[Clinical observation on effect of xuejie jiawei decoction on vaginal hemorrhagic amount and duration in patients after drug-abortion].

OBJECTIVE: To observe the effect of Xuejie Jiawei Decoction (XJJWD) in reducing vaginal hemorrhagic amount, shortening hemorrhagic duration and lowering the curettage rate of incomplete abortion in patients after drug-abortion. METHODS: Group A was treated with XJJWD No. I from the 2nd day after abortion, one dose per day for 7 days. Group B was treated with XJJWD No. II from the 11th day after abortion, one dose per day for 5 days. The therapeutic effect of the two groups was compared with that of the untreated control group. RESULTS: In the Group A, the total score on vaginal hemorrhagic amount was markedly less than that in the control group (P < 0.01), and the vaginal hemorrhagic duration in patients with menostasis less than 45 days was shorter than that in the control group (P < 0.01). In the Group B, the total score on vaginal hemorrhagic amount in patients with menostasis less than 45 days was lower than that in the control group (P < 0.05). CONCLUSION: XJJWD could reduce the vaginal hemorrhagic amount and duration in patients after drug-abortion. It should be applied early after abortion, the less the duration of menostasis, the more effective the treatment.
