Feed additive for preventing soft shell disease of macrobrachium rosenbergii

Abstract

The invention relates to a feed additive for preventing soft shell disease of macrobrachium rosenbergii, which comprises the following raw materials by weight (based on the adding amount of a ton of feeds): 50-100g of vitamin A, 150-400g of vitamin C phosphate, 30-80g of vitamin E, 8-10g of vitamin D, 50-100g of inositol, 2000-2500g of calcium lactate, 1000-1500g of magnesium sulfate and 310-1712g of shell powder. The feed additive has the advantages that: (1) the adding amount in a prawn feed is only 0.5-1%; (2) the vitamins and mineral substances required by the growth of the shell of the prawn are supplemented and maintained, calcium deposition is adjusted and the hardness and smoothness of the shell of the prawn are increased; (3) the growth and deposition of chitin and calcium of organism are boosted and the shell ratio is synchronously increased; (4) the stress resistance and anti-stress capacity of the organism are enhanced, and meanwhile, the effects of protecting liver and detoxifying, boosting digestive absorption and increasing the use ratio of feed are achieved; and (5) the raw materials adopted by the additive are stable in resource and low in cost, and the production process is simple.

Description

technical field [0001] The invention relates to the technical field of aquaculture feed, in particular to a feed additive for preventing macrobrachium rosenbergii soft shell disease. Background technique [0002] Macrobrachium rosenbergii, also known as Malaysian prawns, is commonly known as big-headed shrimps and is one of the large freshwater shrimps. Macrobrachium rosenbergii has the characteristics of large body, fast growth, easy breeding, plump and delicious meat, and is deeply loved by farmers and consumers. In recent years, with the continuous expansion of the breeding scale and the increase of the stocking density, a large amount of high-protein feed has been fed for a long time, causing water pollution, coupled with the degradation of seed germplasm, and the diseases of Macrobrachium rosenbergii have gradually increased, especially the soft shell of Macrobrachium rosenbergii The occurrence of disease not only affects the survival rate of aquaculture, but also adve...
