Embodiment 1

[0013] It is used as an additive for pig feed, and the amount added is 20-3500mg per kilogram of feed in terms of zinc. Experiments with basic zinc chloride in weaned piglets. 72 weaned piglets were divided into three groups, each group had three replicates (pens), and each pen had 8 piglets. The origin, age and body weight of the piglets are similar, and the sexes are the same. Two groups of basal rations were consistent, the test group was added with 1500 mg of basic zinc chloride monohydrate (calculated as zinc) per kg of feed, and the test group was added with 3500 mg of basic zinc chloride monohydrate (calculated as zinc) per kg of feed. The group did not add basic zinc chloride monohydrate. The result is as follows:

Embodiment 2

[0023] It is used as a feed additive for poultry animals, such as chickens, ducks, etc. The amount added is 20-300 mg per kilogram of feed in terms of zinc. Feed experiment of broiler chickens with basic zinc chloride. The 320 Aviin broilers hatched from the same batch were divided into two groups, each group had four replicates (columns), and each group had 40 broilers. The basic diets of the two groups were the same. The test group was supplemented with 120 mg of anhydrous basic zinc chloride (calculated as zinc) per kg of feed, and the control group was not added with anhydrous basic zinc chloride. The result is as follows:

Embodiment 3

[0032] It is used as a feed additive for aquatic animals, such as shrimp, crab, fish, etc.; the added amount is calculated as zinc, and 20-300 mg per kilogram of feed. Feeding experiment of crucian carp with basic zinc chloride. Select 320 crucian carp with an average body weight of 113.5g, divide them into two groups, each group has 8 replicates (aquarium), and each box has 20 fish. The basic diets of the two groups were the same. The test group was supplemented with 300 mg of anhydrous basic zinc chloride (calculated as zinc) per kg of feed, and the control group was not added with anhydrous basic zinc chloride. The result is as follows:

Abstract

Alkali zinc chloride as feed level zinc source has the features of high bioavailability, stable quality, less reaction with the other components in feed, etc. As feed additive, alkali zinc chloride can replenish zinc to animal, promote growth of animal, raise feed utilization, and prevent and treat piglet diarrhea. It may be used to replace antibiotic in promoting animal growth to avoid residue of antibiotic in animal body.

Description

technical field [0001] The invention belongs to an animal feed additive, and in particular relates to the application of basic zinc chloride as an animal feed additive. Background technique [0002] Zinc is an essential trace element for animals, which is required for animal growth, bone development, fur health, appetite and biochemical metabolic activities of the body. Usually animal compound feed needs to be supplemented with zinc, and the common sources of zinc in the feed industry are feed grade zinc sulfate and zinc oxide. These two sources of zinc have their own advantages and disadvantages. Zinc sulfate is easily soluble in water and has high bioavailability. Among them, zinc ions are more active and easily react with other ingredients in the feed, and promote the formation of free radicals, resulting in the destruction of vitamins and other ingredients in the feed. Loss; zinc oxide is not easy to react with other ingredients in the feed, but the bioavailability is l...
