Problems solved by technology

Generally speaking, the residual zinc content in feces is about half of the added amount, such a high dose of zinc accumulates in the soil and causes environmental pollution
Long-term accumulation can cause the soil to no longer be arable
Moreover, zinc is highly toxic to fish and aquatic organisms
Excess zinc excreted by livestock will seriously pollute groundwater and hinder the sustainable development of animal husbandry
2) Cause high zinc dependence of piglets, which will have adverse effects on later growth
Long-term high-zinc feeding will cause pig growth inhibition, decreased feed intake, pale skin, rough and curly coat, etc.
The main reason is that the inhibitory effect of zinc on intestinal bacteria works on both harmful bacteria and beneficial bacteria. When high-dose zinc is used for a long time and the use is stopped, pathogenic bacteria are more likely to colonize and multiply in the intestinal tract than beneficial bacteria, resulting in intestinal bacteria. group disorder and induce diarrhea, which has adverse effects on later growth

Abstract

The invention discloses a preparation method of a diarrhea-preventing feed additive for roasters, and belongs to the technical field of veterinary biological products. The method comprises the following steps: (1) surface modification of palygorskite: heating the palygorskite in a gradient manner, and then modifying the palygorskite by using an efficient active dispersing agent to obtain modifiedpalygorskite; and (2) compounding and cementing of zinc oxide-palygorskite: mixing modified palygorskite powder with composite zinc oxide, then adding an adhesion promoter solution, enabling the modified palygorskite to be functionally compounded and cemented with the zinc oxide, magnetically stirring uniformly, and after drying, grinding into powder to obtain the additive. In total, the preparedfeed additive for roasters has efficient diarrhea-preventing effect, the gastrointestinal environment of the roasters can be improved, and the gastrointestinal adaptation ability of the roasters in aweaning stage is improved.

Description

technical field [0001] The invention belongs to the technical field of veterinary biological products, and in particular relates to a preparation method and a device for a feed additive for suckling pigs to stop diarrhea. Background technique [0002] Zinc is an essential trace element in animals, a component of various enzymes, and participates in the metabolism of nutrients such as fat, carbohydrates, and vitamins. A large number of studies in the fields of medicine and animal nutrition have found that zinc is closely related to the immune function of the body, affecting the specific, non-specific and intestinal mucosal immune function, and plays an important role in maintaining the normal immune function of the body and preventing bacteria and parasites. Good effect on invasion. Studies have shown that adding high doses of zinc oxide to diets can reduce diarrhea and increase daily weight gain in weaned piglets. Scholars at home and abroad have conducted extensive researc...
