The experiment was to study the effect of compound Chinese herbal medicine additive on growth performance and serum biochemical indexes of Suyou No. 2 meat ducks. A total of 240 20-day-old Suyou No. 2 meat ducks were randomly divided into four groups with three replicates in each group and 20 ducks (male and female in half) in each replicate. Ducks in group A were fed with basic diet, group B, C and D were fed with salinomycin, 0.1% and 0.2% compound Chinese herbal medicine preparations, respectively. The pre-test period was 7 d, and the test period was 35 d. The growth performance of ducks was measured on 1 d and 35 d of the experiment, and the serum biochemical indices of ducks were measured on the 7, 14, 21 and 35 d of the experiment. The results showed that compared with group A, the daily gain, daily feed intake and crude protein metabolic rate of group C and group D were significantly increased, and the feed to gain ratio of ducks was decreased (P<0.05). The contents of IL-2, IgA, IgG, IgM and TP in serum of group C and group D were significantly higher than those of group A (P<0.05). Complement C3 and AKP contents in group C and group D were significantly higher than those in groups A and B (P<0.05). Serum BUN in group B, C and D was significantly lower than that in group A (P<0.05). The experiment indicates that adding salinomycin, 0.1% and 0.2% compound Chinese herbal medicine additives to the diet can effectively improve the growth performance and immune function of Suyou No. 2 meat ducks, and the optimal supplemental level of compound Chinese herbal medicine additive in the diet of Suyou no.2 meat duck is 0.2% in order to reduce feed cost and feed waste.

Aspect-oriented specification is a key technology in software architecture modeling and analysis. However, the cur-rent available methods cannot provide adequate support for detailed description of architectural aspects and their weaving logic. There was also a lack of effective methods for the analysis and evaluation of these aspects. This paper used Petri nets as a uni-fied basis to describe the behavioral aspects and structural aspects of software architecture, and proposed a formal approach to specify architectural aspects and their weaving logic. It further illustrated and analyzed the related concepts and models with useful examples. The application research shows that, the framework has powerful describing capability, which can not only be used for the description of architectural aspects from the viewpoint of structure, behavior and the complex weaving logic, but also be used to reason and evaluate the weaving effect.
