Antioxidant Indexes and Immune Function of the Intestinal Flora of Compound Microecological Preparations.

Abstract

Compound probiotics are biological products made by mixing and cultivating various probiotics according to appropriate composition and ratio. It can not only play the role of a variety of probiotics in composition but also the effect of the ratio is often greater than the effect of the single strain alone. These probiotics are good for the body's immune system in living organisms. They act as immune boosters in living organisms. They are considered the safest form of treatment. In this review, the effects of microecological agents on antioxidant indices and immune function of chicks were studied, and radial basis neural network (RBFNN) was described. Aiming at the deficiency of traditional RBFNN learning strategy, a three-layer RBFNN method based on immune mechanism was proposed. In this paper, the microecological evaluation preparation was added into chicken feed. The study showed that chickens fed with probiotics gained significant body weight at 6 weeks of age. Compared with the control group, the experimental group increased by 15.70%. In each feed/gain ratio, the feed/gain ratio of the experimental group was significantly decreased at 6 weeks of age, which was 30.37% lower than that of the control group. Compared with the control group, the spleen, bursa of Fabricius, and thymus of the experimental group were increased by 63.02%, 38.77%, and 26.82%, respectively, indicating that the compound probiotics could improve the immunity of chickens.
