Juvenile penaeus vannamei temporary rearing special feed formula and use method thereof

Abstract

The invention discloses a juvenile penaeus vannamei temporary rearing special feed formula and a use method thereof. The formula comprises the following main components of viable bacteria, organic acid, enzyme, trace metabolites, immunoenhancement substances, organ protection substances, energy supply substances and vitamins. A specific preparation process comprises the following steps of S1, performing superfine grinding, specifically putting 100 parts of organic acid, enzyme, trace metabolites, immunoenhancement substances, organ protection substances, energy supply substances and a vitamin mixture A into a ball mill, and performing superfine grinding to obtain a mixture B; According to the juvenile penaeus vannamei temporary rearing special feed formula and the use method thereof, through the treatment of activity retention technologies such as superfine grinding, high-temperature inactivation, aerobic and anaerobic multi-time alternate fermentation, deep kneading slow mixing, low-temperature granulation and positive-pressure anaerobic packaging, the characteristics that granular feed is low in scatter ratio in water, comprehensive in single granule nutrition, capable of conforming to the feeding habit of prawns, convenient in feeding, and the like are achieved, and the functional substance richness and the application effectiveness of a product are guaranteed.

Description

technical field [0001] The invention relates to the technical field of feed preparation for shrimp seedlings, in particular to a formula of a special feed for the standard thickness of Penaeus vannamei seedlings and a method for using the same. Background technique [0002] In the life cycle of prawns, the growth rate of the seedling stage is slightly faster than that of the grow-out stage, and the quality and sum of the nutrient requirements are higher than that of the grow-out stage. Due to the weak capture and feeding ability, in the long-term evolution process of shrimp, they mainly feed on algae, Artemia, organic broken nets, etc. and prefer plant-based ravioli. The dependence of animal amino acids such as (Met) is slightly lower than that in the growing stage. In terms of fatty acids, from the larvae to feed gradually and use external ravioli containing high unsaturated fatty acids (HUFA), the juvenile shrimp stage has the ability to grow, but it is still tricky and s...

Problems solved by technology

[0003] In the existing feed, about 80% of the functional substances are unstable and prone to heat sensitivity (Lactobacillus acidophilus, Lactobacillus plantarum, Candida utilis, amylase, protease, fiber cable board vitamin C and vitamin E) and easy oxidation ( EPA DHA) is volatile (partial organic whip), and in the common feed production process, it is difficult to guarantee the activity due to the processing links such as ring die extrusion, ripening and drying, so the nutrition of the feed is difficult to be absorbed by the shrimp seedlings
