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,

Embodiment 1

[0032] Embodiment 1 compound Chinese herbal medicine preparation

[0033] The high-quality Chinese herbal medicine Rhodiola rosea from Changbai Mountain in Jilin Province was used, the rough bark was removed and washed, the slices were dried at 80°C to constant weight, and crushed to 60 mesh for use. The content of salidroside, the main active ingredient, is above 800 mg / g as determined by high performance liquid chromatography.

[0034] Astragalus membranaceus is the Mongolian Astragalus membranaceus that has been artificially cultivated for more than 3 years. The whole plant of Astragalus membranaceus picked is washed and dried in the air at a temperature of 60°C for 30 minutes, and crushed by a grinder through an 80-mesh sieve for use. The content of astragalus polysaccharide, the main active ingredient, is above 180 mg / g, and the content of astragaloside IV is above 0.5 mg / g, as determined by high performance liquid chromatography.

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 cost of livestock and poultry production depends largely 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 ingeste...
