Tilapia feed taking cotton seed meal and rapeseed meal as main protein materials

Abstract

The invention provides a tilapia feed taking cotton seed meal and rapeseed meal as main protein materials, belonging to the technical field of fish feed. The tilapia feed is characterized by comprising the following components by weight percent: 10-26 percent of cotton seed meal, 30-50 percent of rapeseed meal, 0-20 percent of soybean meal, 15-40 percent of sub-powder, 0.1-1.5 percent of tangerine peel, 0.3-1.5 percent of dry leaves of eucommia bark, 0.5-4 percent of calcium hydrophosphate, 0.1-0.3 percent of compound vitamin, 0.1-0.5 percent of compound trace ore element, 0.1-0.5 percent of salt and 0.5-3 percent of compound premix. The tilapia feed obviously reduces the toxic action of biological toxin substances in the cotton seed meal and the rapeseed meal to the tilapia, obviously improves the meat quality of the tilapia, and is not added with any antibiotics, hormone and veterinary drug; the growth speed of the tilapia is fast, the feed coefficient is low, and the feed has good stability in water, and does not pollute aquaculture water bodies easily; and the materials are simple and easily obtained, the cost is low and the aquaculture cost can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of feed processing. Specifically relates to a tilapia feed formula with cottonseed meal and rapeseed meal as main protein raw materials. Background technique [0002] Tilapia, native to Africa and the Middle East, has a series of advantages such as miscellaneous food, fast growth, strong disease and stress resistance, easy breeding, and high yield, and can be cultured in fresh water, brackish water and even sea water. It is one of the varieties promoted by the Food and Agriculture Organization of the United Nations. Its low price and good meat quality make it known as "the fish of the people in the 21st century". Tilapia is farmed in 100 countries and regions all over the world, and it has become the world's most important farmed fish after carp, with an annual output of about 2.5 million tons in the world. [0003] After the introduction of tilapia in my country in 1978, it rapidly developed into a fast-...

Problems solved by technology

There are mainly acidification method, alkalization method, water immersion method, organic solution extraction method, heat treatment, water washing, chemical detoxification, microbial fermentation and other detoxification methods. However, these detoxification methods have complex production processes and detoxification in practice. Cottonseed meal and rapeseed meal, which are high-volume protein raw materials, have not been fully utilized in the field of feed due to problems such as high cost, serious loss of nutrients, large environmental pollution, and incomplete detoxification.
