Embodiment 1

[0028] First, vitamin C and vitamin E were purchased from Hangzhou Ailimai Pharmaceutical Co., Ltd., and bile acid was purchased from Longchang Animal Health Co., Ltd. Dissolve vitamin E, vitamin C and bile acid in water and evenly spray on the surface of the basic feed, and then The feed is wrapped with fish oil and dried to obtain the feed containing compound immune growth enhancer. Among them, 0.03g of vitamin C, 0.02g of vitamin E and 0.05g of bile acid were added per kilogram of basic feed. The composition of the basic feed is: in terms of mass fraction, 34% of fish meal, 20% of soybean meal, 16.4% of peanut meal, 22% of wheat flour, 5% of soybean lecithin, 0.6% of multivitamins, and 2% of compound minerals.

Embodiment 2

[0030] The difference from Example 1 is that 0.03 g of vitamin C, 0.02 g of vitamin E and 0.2 g of bile acid are added per kilogram of basal feed.

[0031] The following combined experiments illustrate the present invention's ability to promote the growth of prawns, enhance the immune defense ability and bactericidal effect of prawns.

Abstract

The invention relates to a compound feed additive and application thereof and provides a compound immunity growth enhancer for prawns and application thereof. In addition, the invention also providesa feed containing the compound immunity growth enhancer for prawns. The compound immunity growth enhancer for prawns is prepared from, by mass, 10%-30% of vitamin C, 5%-20% of vitamin E and 50%-80% ofbile acid. The compound immunity growth enhancer for prawns has the effects of promoting prawn growth and improving immune defense ability and bactericidal effect of the prawns, effectively improvesfat metabolism of the prawns, promotes prawn growth, decreases the use amount of antibiotics and chemicals, can obviously improve the immune defense ability and growth rate of prawns, can promote protein and fat metabolism of prawns and improve the immune defense ability of prawns and provides technical support for healthy sustainable development of prawn breeding.

Description

technical field [0001] The invention relates to an aquatic compound feed additive and its application, in particular to a prawn compound immune growth enhancer and its application. Background technique [0002] In recent years, the aquaculture industry has developed rapidly. According to the latest statistics from the Food and Agriculture Organization of the United Nations (FAO), in 2016, the output of crustaceans in my country was 7.86 million tons, and the output of Litopenaeus vannamei was 1.67 million tons, accounting for 83% of the total output of prawns in my country. %, it can be seen that shrimp occupies an important position in the aquaculture industry. In order to pursue higher economic benefits, with the continuous development of intensive culture of prawns, there are frequent occurrences of prawn diseases, which are becoming more and more serious. The blind pursuit of rapid growth of prawns, the excessive addition of protein and fat in the prawn compound feed cau...
