Abstract

The invention belongs to the technical field of animal husbandry and particularly relates to zinc-rich probiotics for improving the immune function of cage-free local chickens and a preparation methodof the probiotics. The zinc-rich probiotics is prepared from, by weight, 10-15% of a candida utilis seed solution, 5-15% of white tea yeast, 5-10% of a lactobacillus acidophilus seed solution, 5-10%of an enterococcus faecium seed solution, 10-15% of a bacillus subtilis seed solution, 3-5% of an activator and 40-50% of a zinc-rich fermentation culture medium. The preparation method comprises thesteps that all the raw materials are weighed, then mixed at 35 DEG C and cultured for 20-30 h, after culture is ended, the mixture is placed in a hollow drying box at 60 DEG C, drying is conducted for1 h, after drying, low-temperature smashing is conducted, and the zinc-rich probiotics for improving the immune function of the cage-free local chicken is prepared. According to the zinc-rich probiotics, a targeted feed additive can be provided for the growth environment of the local chickens mostly through an enclosure cage-free mode in the mountains and used for improving the immune function ofthe cage-free local chickens, and the diseases of chicken flocks and antibiotic misuse phenomena are reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of animal husbandry, in particular to a zinc-rich prebiotic for improving the immune function of free-range chickens and a preparation method thereof. 【Background technique】 [0002] In recent years, with the improvement of people's living standards, the demand for green and pollution-free food has gradually increased. As a green and pollution-free livestock product, free-range free-range chickens without resistance under the forest are generally favored by consumers because of their delicious meat quality, no use of feed additives, especially the use of antibiotics and hormones, and the safety of the livestock products produced. However, there is a problem in free-range breeding without antibiotics: in the absence of antibiotics as preventive drugs, the disease incidence and mortality of chickens will increase significantly, causing economic losses and increasing feeding costs. Looking for a green veteri...
