Abstract

The invention discloses a preparation method of a probiotic fermentation cattle feed additive. The method comprises the following steps: 1, pre-processing; 2, taking 20-40 parts of mulberry leaf, 5-10 parts of Sorghum sudanense, 10-20 parts of Eichhornia crassipes, 5-15 parts of hawthorn fruit, 10-30 parts of purslane, 10-15 parts of licorice root, 5-10 parts of sweet clover, 5-10 parts of Rheum officinale and 10-15 parts of Radix Platycodonis, mixing to obtain a mixture, adding water having same amount with the mixture, and carrying out pulp refining; 3, adding Bacillus subtilis and Aspergillus niger to the obtained pulp, and carrying out sealed fermentation to obtain a fermentation stock solution; 4, inoculating a Lactobacillus acidophilus nutrient solution into the fermentation stock solution, and fermenting to obtain a primary fermentation solution; and 5, adding sodium chloride to the primary fermentation solution, carrying out standing fermentation to obtain a secondary fermentation solution, filtering, and recovering and preserving the above obtained filtrate. The filtrate can be used in cattle feeds as an additive in order to improve the palatability; and the additive can enhance the colonization ability of beneficial bacteria in the intestinal tract, promotes digestion and absorption, enhances the immunity, improves the disease resistance of bodies, and reduces the incidence of diseases.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and in particular relates to a preparation method of a probiotic-fermented cattle feed additive.

Problems solved by technology

In recent years, there have been many problems in cattle feeding. For example, due to various factors such as improper feeding management and unbalanced rations, the growth rate of beef cattle is slow, the quality of beef is not good, the milk production of dairy cows is low, and the incidence of diseases In response to this problem, antibiotics are widely used as feed additives in the market. Although good results have been achieved, there are problems of drug residues, drug resistance of pathogens, environmental problems, and livestock and poultry digestion. The problem of normal flora imbalance, the decline of immune function of livestock and poultry, serious drug residues in cattle, and serious damage to the health of cattle and humans

As many problems caused by the use of antibiotic additives have been reported, relatively safe Chinese herbal medicine feed additives have begun to appear on the market. Some Chinese herbal medicines are relatively expensive, leading to an increase in breeding costs. Side effects, leading to the reduction of beef quality, and pose a greater threat to food safety
