Problems solved by technology

[0003] At present, the growth and development stages of Penaeus vannamei also have large differences in nutritional requirements. At present, there is no scientific ratio for the feed in the middle growth stage of Penaeus vannamei. Generally, ordinary feed is used. The growth of Penaeus vannamei is poor, which affects Penaeus vannamei. Post-growth weight gain

Abstract

The invention discloses a preparation method of feed for promoting growth of litopenaeus vannamei. The method comprises the following steps: uniformly mixing meat and bone meal, blood worms, ampullaria gigas, shell powder, sorgo, fermented soybean meal, pregelatinized potato starch and seaweed meal, adding grapefruit juice and water to be uniformly mixed, steaming, filtering, drying, and grinding to obtain pretreated main ingredients; and adding peanut oil, olive oil, propylene glycol alginate, taurine, vitamin and mineral salt into the pretreated main ingredients to be uniformly stirred, adding modified whey protein in a stirred state, granulating, drying, thereby obtaining the feed for promoting growth of litopenaeus vannamei. The feed obtained according to the invention is comprehensive in nutrition, excellent in feeding attraction and high in food conversion rate and meets the requirements on various nutritional ingredients in the growth metaphase of the litopenaeus vannamei. Moreover, digestion of the litopenaeus vannamei can be effectively promoted, the disease immunity of the litopenaeus vannamei is enhanced, and the case fatality rate of the litopenaeus vannamei is low.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a feed preparation method for promoting the growth of Penaeus vannamei. Background technique [0002] Vannamei shrimp is commonly known as white limb shrimp, white shrimp, South American shrimp and so on. my country introduced Penaeus vannamei seedlings from the United States in 1988, and successfully carried out productive breeding and breeding in 1994. Penaeus vannamei is large in size, has strong disease resistance and adaptability, and has a fast growth rate. It can be cultured in low-salinity and fresh water. It can survive out of water for a long time, with delicious meat and a high rate of processed meat. [0003] At present, the growth and development stages of Penaeus vannamei also have large differences in nutritional requirements. At present, there is no scientific ratio for the feed in the middle growth stage of Penaeus vannamei. Generally, ordinary feed is used. The gr...
