Pig premix feed with low protein, high amino acid and high digestion and utilization rate, and preparation method of pig premix feed

Abstract

The invention discloses a pig premix feed with low protein, high amino acids and high digestion and utilization rate. The pig premix feed comprises the following ingredients in percentage by weight: 10-30wt% of 46% soybean meal, 10-30wt% of fermented soybean meal, 10-30wt% of corn DDGS, 3-8wt% of fish meal, 3-6wt% of dicalcium phosphate, 5-15wt% of stone powder, 1-3wt% of sodium chloride, 1-3wt% of a multi-vitamin premix agent, 1-3wt% of a multi-mineral premix agent, 0.1-0.5wt% of phytase 10000, 0.1-0.5wt% of complex enzymes, 0.1-0.5wt% of micro-ecological funguses, 0.5-1.0wt% of 70% choline chloride, 5-15wt% of 70% feed-level lysine, 0.1-0.5wt% of methionine, 0.2-0.7wt% of threonine, 0.05-0.15wt% of tryptophan, 0.05-0.15wt% of valine, 0.1-0.4wt% of a solid antioxidant, 0.1-0.3wt% of a mildewproof agent, 0.05-0.2wt% of a sweetening agent, 0.05-0.2wt% of a flavoring agent and 0.05-0.2wt% of an acidulant. The problems of high cost of ingredients, high feed conversion rate, serious pollution of dung and urine and the like caused by high protein content in designed feeds are solved; and besides, the use of soybean products is reduced, protein raw materials are saved, the food supply pressure is alleviated, and the dependence of China on imported soybeans from foreign countries is reduced.

Description

technical field [0001] The invention belongs to the technical field of animal feed, and in particular relates to a premixed feed for pigs and a preparation method thereof. Background technique [0002] China is a big pig raising country, and the breeding volume accounts for more than half of the world. A large amount of feed materials are needed in the breeding process. Due to the formula technology and breeding habits, most of the current pig farming in my country tends to use high-protein pig compound feed. digestion and absorption utilization. [0003] With the success of industrial production of individual amino acids, beneficial microorganisms for feed, and enzyme preparations, it has become possible to use amino acids to balance and meet the protein needs of diets, and it has also become possible to use beneficial microorganisms and enzyme preparations to improve the digestion, absorption and utilization of protein in feed. It is possible, that is to say, the success ...

Problems solved by technology

[0006] In view of the existing problems at present, the purpose of the present invention is to provide a pig premixed feed with low protein, high amino acid and high digestibility and utilization rate, so as to solve the problems of high ingredient cost, high feed-to-meat ratio and fecal waste caused by the high protein content of the designed feed. Serious urine pollution and other problems, while reducing the use of soybean products, saving protein raw materials, alleviating the pressure on food supply, and reducing China's dependence on foreign soybean imports
