Abstract

The invention discloses a preparation method of a feed additive for preventing inflammation of muscular gaster and proventriculitis of broiler chickens. The preparation method comprises the following steps of uniformly mixing chitosan with an ascorbic acid aqueous solution, adding beta-cyclodextrin under a stirring state, keeping stirring, feeding the stirred materials to a supercritical fluid expansion reactor, introducing carbon dioxide gas, spraying the carbon dioxide gas from a nozzle, adding complex vitamins, complex trace elements, astaxanthin and probiotics, performing uniform mixing, and adjusting the water content so as to obtain a chitosan compound; peeling tripterygium wilfordii roots, performing crushing, adding water, performing soaking, performing filtration to remove moisture, performing air drying on surfaces, performing freezing treatment, performing slow heating, standing, performing grinding, adding extracellular enzymes, performing fermentation, and performing filtration so as to obtain enzymolysis tripterygium wilfordii; adding stearic acid, glyceride and calcium chloride to an ethanol aqueous solution, and performing uniform stirring so as to obtain a coating solution; and adding the enzymolysis tripterygium wilfordii to the chitosan compound, performing uniform stirring, performing granulation, then making pellets, and coating the pellets with the coating solution so as to obtain the feed additive for preventing inflammation of muscular gaster and proventriculitis of broiler chickens.

Description

technical field [0001] The invention relates to the technical field of poultry feed additives, in particular to a feed additive for preventing broiler gizzard glandular gastritis and a preparation method thereof. Background technique [0002] In recent years, a disease characterized by glandular gastritis and muscle gastritis has gradually become popular in most commercial broiler breeding areas in my country. Even failure to death, autopsy symptoms mainly manifested as glandular stomach swelling, gizzard corneum necrosis, intestinal swelling, catarrhal or hemorrhagic inflammation. The etiology of the disease is complex, and it is related to environmental humidity, feed mold, virus, bacteria, etc. [0003] In recent years, with the development of broiler breeding industry, glandular gastritis and gizzard erosion have developed into common diseases that endanger the poultry breeding industry, bringing greater economic losses to farmers. The clinical symptoms and pathological...
