Fish feed additive capable of improving growing performance

Abstract

The invention discloses a fish feed additive capable of improving growing performance. The fish feed additive is prepared from the following raw materials in parts by weight: 30-40 parts of rapeseeds, 5-6 parts of ginkgo leaves, 6-7 parts of camellia, 10-15 parts of fragrant citrus pericarp, 20-25 parts of black glutinous rice, 7-12 parts of fresh ginger, 20-25 parts of potatoes, 7-9 parts of Chinese prickly ash, 15-20 parts of fresh peach leaves, 3-4 parts of white vinegar, 4-5 parts of Baijiu, 5-6 parts of white sugar, an appropriate quantity of lactic acid bacteria, an appropriate amount of bacillus subtilis and an appropriate amount of water. The Chinese prickly ash treated at low temperature can avoid the smell of burnt food from appearing, and after the Chinese prickly ash pressed liquor performs powder injection, the effects of resisting bacteria, diminishing inflammation, prompting appetite and adjusting internal lipid metabolism can be achieved. The fresh peach leaves have the efficacies of clearing heat and removing toxicity. The Baijiu can enable effective components of the peach leaves to be dissolved. The white vinegar can remove toxicity, and restrain bacterial reproduction. The fresh ginger has the effects of promoting digestive juice secretion, resisting oxidation, resisting tumors, resisting inflammation, resisting microorganisms and the like. Dreg materials can promote beneficial anaerobic bacteria to grow after being fermented with the bacillus subtilis, so that the immune function is strengthened.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a fish feed additive for improving growth performance. Background technique [0002] Rapeseed meal is rich in protein and amino acids, and is a good source of plant-based feed protein. However, due to the presence of anti-nutritional factors such as glucosinolates, tannins, and phytic acid in rapeseed meal, it affects the safety, palatability and utilization rate of nutritional value of feed, thus limiting its use in diet. After rapeseed meal is solid-state fermented by microorganisms, it can reduce the crude fiber content, effectively remove anti-nutritional factors, improve its palatability, and at the same time produce small molecular weight peptides and probiotics, regulate the microecological balance of the gastrointestinal tract of animals, and improve Digestive enzyme activity. In addition, microbial protein itself is also a high-quality protein resource, which can increase...
