Abstract

The invention discloses a feed additive for improving growth immune function of broilers, and the feed additive includes astragalus, folium isatidis, herba leonuri, hawthorn, malt, medicated leaven, pine needle powder, gastrodia armillaria mellea powder and a carrier. The invention also provides a preparation method and an application method of the feed additive. A variety of Chinese herbal medicines and the gastrodia armillaria mellea are used as main raw materials for preparing the feed additive to realize the coordination linkage of the Chinese herbal medicines and the gastrodia armillaria mellea, the broiler daily feed intake and daily weight gain are significantly increased, the mortality and the feed conversion ratio are decreased significantly and the broiler immunity (including immune organ indexes, hemagglutination inhibition antibody titer, peripheral lymphocyte transformation rate, NK (natural killer) cell activity, IL (interleukin) activity indexes) is significantly enhanced.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and in particular relates to a feed additive for improving the growth immunity of broilers, a preparation method and an application thereof. Background technique [0002] With the development of intensive livestock breeding production mode, factors such as deteriorating feeding environment and unbalanced or insufficient nutrients have led to low animal immunity, manifested as slow growth, increased feed-to-meat ratio, increased mortality, and farmers’ losses. Affect the market supply of livestock products. At the same time, the stress effect of intensification makes animals restless, which is an external manifestation of stress. In order to resist stress, animals consume a large amount of nutrients to balance various metabolisms, and the performance of livestock and poultry breeding is reduced. Production requires suitable products and technologies to solve the above two problems. [000...
