Abstract

The invention discloses penaeus orientalis feed. The feed comprises fish meal, soybean meal, peanut bran, flour, beer yeast, shrimp head meal and a feed additive, wherein the feed additive contains beta-hydroxybutyrate. The feed can promote the growth of litopenaeus vannamei, increase the crude protein content of the whole penaeus orientalis body, maintain the structure of intestinal tissues, increase the short-chain fatty acid content of intestines and regulate the microbial community structure of the intestines so as to effectively improve intestinal health.

Description

technical field [0001] The invention belongs to the field of aquaculture, in particular to a feed formula for improving the intestinal health of prawns. Background technique [0002] Shrimp is an important species of marine culture in my country, which has made important contributions to promoting economic growth and increasing fishermen's income. In recent years, with the continuous deterioration of intensive farming and ecological environment, shrimp diseases frequently broke out, causing serious economic losses. For example, in the "early death syndrome" or "acute hepatopancreatic necrosis syndrome" of prawns, the main pathogen Vibrio parahaemolyticus is transmitted orally and colonized in the intestines of prawns, producing toxins that cause tissue damage, resulting in liver dysfunction and digestive system disorders obstacles, which in turn lead to mass mortalities of prawns. The intestine is not only the main place for nutrient digestion and absorption of shrimp, but...
