Problems solved by technology

However, most of the Chinese herbal medicine additives currently on the market are crude products such as powders or powders, which are not conducive to full absorption, slow effect, low efficacy, and serious waste; poor dosage forms make the dosage of Chinese herbal medicine feed additives too large, usually 1 to 3%. , some as high as 5-10%

Embodiment 1

[0023] 1) Preparation of copper-modified montmorillonite: (a) the montmorillonite mineral after depolymerization, dispersion, separation and purification, together with sodium chloride equivalent to 15% of the mineral weight, is added with water and stirred evenly to make a concentration of 20%. Suspension pulp, washed 7 times; (b) adding Cu(NO) equivalent to 30% of mineral weight 3 ) 2 , re-made a 5% pulp with water, adjusted the pH value with dilute sodium hydroxide solution, washed 5 times with water, and filtered; (c) the filter residue was vacuum-dried at a temperature lower than 80° C., and dried with a jet mill. For the copper-modified montmorillonite prepared according to the above steps, the content of copper element in the copper-modified montmorillonite is 8.5%.

Abstract

A feed nano additive with health-care and growth-promoting functions is prepared from Cu-modified montmorillite, Zn-modified montmorillite and composition of astragalus' active component and montmorilite through proportioning. Its advantages are strong antibacterial and -antivirus power, high effect on increasing survical rate, promoting growth and resisting diseases, and high conversion of feed.

Description

technical field [0001] The invention relates to a nano feed additive with health-care and growth-promoting effects and a preparation method thereof. Background technique [0002] Under the conditions of intensive, large-scale, automated, and mechanized feeding and management of modern animal husbandry, problems such as the deterioration of the ecological environment of animal feeding, the threat of epidemics, stress, and nutritional restrictions require one or more anti-conditional pathogenic microbial drugs, anti- Intervention and application of health care agents such as parasite drugs. As we all know, antibiotic growth promoters, antibacterial and antiparasitic drugs, high-copper, high-zinc preparations, etc. are used as feed additives to promote the growth of animals, prevent the occurrence of pathogenic bacteria infection and diseases, and have a great impact on the development of feed industry and animal husbandry made a great contribution. H...
