Problems solved by technology

When feed-grade zinc oxide is used as an additive to prevent animal diarrhea and promote growth, it needs to be added in a large dose, which can easily cause growth retardation in the later stage of weaned piglets. Large doses of zinc oxide used by animals will increase

Embodiment Construction

[0009] Nano-zinc oxide is used as animal feed additive, and its minimum dosage is calculated as zinc, 10mg per kilogram of feed. It is based on the nutritional needs of various animals and combined with the actual production of existing animals. If it is lower than the addition of 10mg per kilogram of feed in terms of zinc, the application effect is not obvious or has no effect.

[0010] Implementation example

[0011] Nano-zinc oxide is used as an additive for pig feed, and the addition amount is calculated as zinc, and 10-300mg is added per kilogram of feed. Experiment with weaned piglets using nano zinc oxide. 90 weaned piglets were selected for the experiment, and the piglets were similar in origin, age, weight, and male sex. 90 weaned piglets were randomly divided into three groups, with three replicates in each group and 10 piglets in each replicate. The basic diets of the three groups were the same. The experimental group was supplemented with 100 mg of nano-zinc ox...

Abstract

The invention proposes a new usage for nanometer zinc oxide as an animal fodder additive. As a feed zinc source, the nanometer zinc oxide has the advantages of high bioavailability, small additive dosage and stable quality and hard reaction with other components, etc. As the feed additive, the nanometer zinc oxide can effectively supplement the demand of the animals on zinc, promote the animals to healthily grow and enhance the feed use efficiency, can effectively lower the occurrence of the diarrhea of the piglets and avoid causing the drug residue in the livestock products by the use of the antibiotics. With low use dosage, the invention reduces the contamination of the environment caused by the animal excrement. The nanometer zinc oxide promotes the growth, enhances the feed efficiency, replaces the antibiotics as the growth promoters, eliminates the residue of the antibiotics in the animal products, reduces the environmental contamination and produces the pollution-free animal products.

Description

technical field [0001] The invention belongs to animal feed additives, and specifically relates to the application of nanometer zinc oxide as an animal feed additive. technical background [0002] Zinc is an essential trace element for animals. Animal growth, bone development, fur health, appetite and physiological and biochemical metabolic activities of the animal all need zinc. Usually animal compound feed needs to add appropriate zinc element to meet the needs of animals for zinc element. The common zinc source additives in the current feed industry are feed grade zinc sulfate, ordinary zinc oxide, etc. These zinc source additives have their own advantages and disadvantages. Zinc sulfate is easily soluble in water and has high bioavailability. Among them, zinc ions are more active, easily react with other ingredients in the feed, and promote the formation of free radicals, resulting in the loss of vitamins, fats, and amino acids in the feed. Zinc sulfate dissolves rapidl...
