A kind of feed for weaned piglets with low protein and preparation method thereof

Abstract

The invention discloses a low-protein weanling piglet feed which comprises the following raw materials: corns, bean pulp, calcium hydrogen phosphate, dried porcine soluble, fermented bean pulp, fish meal, soybean oil, a premix, sodium chloride, phytase, a compound antioxidant, a compound acidifier, a compound enzyme preparation, a microecological preparation, limestone, L-lysine hydrochloride, L-threonine, DL-methionine, L-tryptophan and a compound traditional Chinese medicine preparation. According to the feed, the crude protein content of piglet full-price daily ration is reduced to 16% from 19%; the compound acidifier, the compound enzyme preparation, the microecological preparation and the compound traditional Chinese medicine preparation are added, so that the immunity of piglets is comprehensively improved and the use of antibiotic drugs is reduced; low-protein high-growth piglet ration is prepared, so that the misunderstanding to the feed consumption caused by farmers is eliminated, the low-protein ration formula technology is really popularized in local, the use of protein raw materials and the diarrhea of the piglets are reduced, and the cost and the N discharge are reduced.

Description

technical field [0001] The invention belongs to the field of feed, and in particular relates to a feed for low-protein weaned piglets and a preparation method thereof. Background technique [0002] At present, the production cost of livestock and poultry mostly depends on the price of protein raw materials in feed. The diets based on corn-soybean meal meet the nutritional requirements of NRC (2012) pigs, and there are different degrees of excess of essential amino acids in the diets. Therefore, by adding synthetic amino acids to the diet, appropriately reducing the dietary protein level, and achieving the highest protein efficiency through the optimal amino acid balance, this is of great significance for reducing the use of expensive protein raw materials and reducing feed costs. [0003] With the expansion of the breeding scale in our country, the environmental pollution caused by animal excrement is becoming more and more serious. About 15% of the total nitrogen ingested...

Problems solved by technology

Although the research on low-protein diets is becoming more and more mature, the promotion is still in its infancy. Farmers always think that feeds with higher crude protein are good feeds for feed consumption.

Moreover, due to the large differences in local and regional environments, the nutritional needs and growth conditions of pigs are different, these inventions have certain limitations, especially the particularity of the northern climate conditions, the long and cold winter, the large temperature difference between day and night, and the heat regulation function of piglets. Well-developed, especially under cold stress, there will be a decrease in feed intake and slow growth, so how to reduce the dietary protein and reduce the use of antibiotics by adding compound Chinese herbal medicines to fully regulate the immunity of pigs , reducing the incidence and increasing the growth rate are the problems to be solved by the patent of the present invention
