Embodiment 1

[0033] This example illustrates the detoxification ability of the chitosan feed additive of the present invention, and improves the immunity of the feeding object.

[0034] The detoxification performance of the chitosan feed additive and the improvement of the immunity of the feeding objects were tested through typical experiments. The specific method is to add less than lethal amount of T-2-toxin to carp feed, causing chronic carp poisoning. Then feed the carp with the feed added with the chitosan feed additive; every day, feed three times, and the feed amount is 3% of the body weight.

[0035] The test results showed that some indicators of carp (phagocyte activity, lysozyme activity, granule hematopoietic activity) were improved, which proves that chitosan feed additive has a high potential of activating immunity.

Embodiment 2

[0037] This example illustrates the impact of the chitosan feed additive of the present invention on poultry feeding.

[0038]The experiment was randomly divided into three groups, two control groups and one test group, with 200 rats in each group. The control group was fed with basal ration; the control group 2 was fed with basal ration+furazolidone+chlortetracycline; the test group was fed with basal ration+chitosan feed additive with different ratios, and the test results were as follows:

[0039] The control group: the weight of the stuffed ducks reaches 3100-3250g, it takes 38-42 days for slaughter, and the mortality rate is 3%. The meat-to-feed ratio of each duck is 3.2kg: 9kg;

[0040] Control group 2: The weight of the stuffed ducks reached 3100-3250g, and it took 38-40 days for slaughter, and the survival rate was 100%. The meat-to-feed ratio of each duck is 3.2kg: 9kg;

[0041] Experimental group: The weight of the stuffed ducks reached 3100-3250g, and it took 36-...

Abstract

A chitosan additive for feed is prepared from chitosan through condensation reaction on the aldehyde containing hydrophilic carboxy or hydroxy radicals to generate enamine, solid reductive reaction on inorganic reducer, washing the resultant depositing in alcohol, vacuum centrifugal drying, and oxidizing hydrolysis. Its advantages are high detoxication performance and high effect to improve immunity.

Description

technical field [0001] The invention relates to a feed additive and its preparation method and application, in particular to a chitosan feed additive and its preparation method and application. Background technique [0002] Freshwater fish live in the water environment and are bound to be affected by many external factors, the main ones being biotic and abiotic. Biological ones include pathogenic bacteria, parasites and other harmful organisms; non-biological ones include water temperature, dissolved oxygen, carbon dioxide, ammonia, hydrogen sulfide, pH value and other ions. Although fish have certain adaptability to these factors, if they exceed a certain range, they will affect the normal physiological activities of fish and cause the decline of fish resistance. [0003] Generally speaking, fish have good physique and strong disease resistance. Although there are pathogens, they are not easy to get sick. Therefore, the factors that affect the health of freshwater fish ar...
