Low-protein piglet daily ration premix using fermentation materials and piglet daily ration containing premix

Abstract

The invention discloses a low-protein piglet daily ration premix using fermentation materials and a piglet daily ration containing the premix. The premix comprises the raw materials in percentage by weight as follows: 10%-15% of stone powder, 10%-15% of calcium hydrogen phosphate, 4%-8% of table salt, 10%-15% of L-lysine hydrochloride, 1%-3% of DL-methionine, 3%-5% of L-threonine hydrochloride, 1.0%-1.5% of a vitamin additive, 1%-3% of a microelement additive, 0.2%-0.3% of a growth promoter, 2%-4% of choline chloride, 0.5%-1.5% of a complex enzyme preparation, 0.2%-0.5% of high-temperature-resistant phytase, 0.3%-0.5% of an antioxidant, 10%-18% of medical stone and the balance of a carrier. The piglet daily ration is obtained by adding calcium hydrogen phosphate, whey powder, glucose, soybean oil, imported fish meal, extruded corn, northeast corn, fermentation materials, extruded soybeans and extruded soybean meal to the premix. The dosage of protein materials in feed can be reduced, the production performance of livestock and poultry is unchanged and slightly improved, the feed conversion rate, nitrogen deposition and nitrogen emission of livestock and poultry and stress capacityare improved, the breeding cost is reduced, the growth speed of pigs is increased, and the environmental pollution caused by pig excrement is reduced.

Description

technical field [0001] The invention relates to the field of animal production, in particular to a low-protein piglet ration premix using fermented raw materials and the piglet ration. Background technique [0002] 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 by growing and finishing pigs is in the form of feces nitrogen, 50% is excreted in the form of urine nitrogen, and nearly 52% of the nitrogen in feces and urine is discharged into the atmosphere in the form of odor, and 48% finally enters the soil (Jacob, 1995), many studies have shown that the supplementation of synthetic amino acids in low-protein diets can greatly reduce the environmental pollution caused by aquaculture. On the premise of not affecting growth performance, the average reduction in dietary protein level by 1 percentage point, About 8%-10% of total nitrogen excr...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the above-mentioned problems that the dietary protein level is reduced, it cannot meet the needs of the types, ratios and quantities of amino acids in the livestock and poultry diets, it is prone to disease, and the production performance of livestock and poultry is reduced. Grain premixes and piglet rations can reduce the amount of protein raw materials in the feed, the production performance of livestock and poultry remains unchanged and slightly improved, and the feed conversion rate, nitrogen deposition and nitrogen discharge of livestock and poultry, and stress capacity are all improved. Reduce the cost of breeding, increase the growth rate of pigs, and reduce the pollution of pig excrement to the environment
