Problems solved by technology

Although the above tilapia feed can ensure the normal growth of artificially cultured tilapia, the rapeseed meal and soybean meal contain various anti-nutritional factors such as sinigrin, erucic acid, phytic acid and tannin, which make its use and dosage If it is greatly reduced, it will seriously damage the health of animals, so that the protein content of tilapia cannot be better improved, and it will affect the higher nutritional value of artificially farmed tilapia

Abstract

The invention provides a compound feed for Tilapia mossambica and a preparation method thereof. The compound feed mainly contains fermented rapeseed meal and fermented soybean meal, and can effectively promote the Tilapia mossambica to digest and absorb food, so that the dressing percentage of artificially cultured Tilapia mossambica is improved, the quality of the Tilapia mossambica is improved,and the huge economic benefit is brought to the aquaculture.

Description

technical field [0001] The invention relates to an animal feed, in particular to a tilapia compound feed. Background technique [0002] Tilapia is an important freshwater farmed fish, known as one of the main sources of animal protein in the future. For a long time, in the process of culturing tilapia artificially, scientific and reasonable formula feed is one of the important components. Chinese patent application CN101984848A discloses a tilapia overwintering feed, which is mainly made of the following raw materials in weight percentage: soybean meal 20-40%, fish meal 0-5%, miscellaneous meal 15-40%, wheat flour 20-35% , fish oil 2 to 5%, vitamin E? 0.03-0.05%; miscellaneous meal is one or more of rapeseed meal, cottonseed meal, peanut meal and rice bran meal; the crude protein and crude fat content of the feed are 25-30% and 5-7% respectively. Chinese patent application CN101756075A provides a kind of feed for tilapia. The components and weight percentages in the feed ...
