Problems solved by technology

[0005] In addition, the endogenous digestive enzyme protease can increase the protein degradation rate, but its activity is easily affected by other ingredients in the premix and preservation and other factors, so it is not added to the premix; protease-producing Bacillus It has strong stress resistance, is not easily affected by the internal and external environment of the body, and can degrade p...

Embodiment Construction

[0052] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific examples.

[0053] The 4% premix formula for growing pigs provided by the present invention is mainly obtained through the following technical solutions: first, according to the net energy regression equation (Noblet etc., 1994), estimate the net energy of corn, soybean meal, bran three kinds of large raw materials, Determine the nutritional needs of 30-60kg growing pigs for net energy during the growth stage; determine the amount of synthetic amino acids lysine, methionine, threonine, and tryptophan in the diet based on the ideal protein amino acid balance model; The ratio of the ratio and the feeding test, the appropriate ratio of corn, soybean meal, and bran in the diet was obtained, and the appropriate amount of synthetic amino acids in the premix was deduced inversely; then accor...

Abstract

The invention discloses a 4% of premix for a growing pig and daily ration prepared by using the premix. The premix consists of composite trace elements, complex vitamins, colistin, virginiamycin, bacillus subtilis subspecies, phytase, sweetener, choline chloride, mountain flour, calcium hydrophosphate, lysine, methionine, threonine, tryptophan, salt, ethoxyquin, rice husk powder and zeolite powder. The daily ration is prepared by the premix, corns, soya bean meal and bran, the using amount of the soya bean meal is reduced by 7% absolutely, the shortage of the protein raw material soya bean meal is effectively relieved, the pig husbandry cost is reduced, and remarkable economic benefit and social benefit are produce. In addition, 18.62% of fecal nitrogen emission is reduced, and the ecological benefit is very remarkable.

Description

technical field [0001] The invention relates to the field of feed, in particular to a 4% premix for growing pigs and a ration prepared by using the premix. Background technique [0002] By reducing the level of crude protein in the diet and improving the digestibility of crude protein in the diet, the excretion of fecal nitrogen from the digestive tract and the discharge of ammonia nitrogen from the respiratory tract can be reduced, so as to achieve the purpose of reducing nitrogen emissions and reducing the cost of protein feed addition. [0003] Reducing dietary crude protein levels is mainly achieved by formulating low-protein diets for pigs. Low-protein diet for pigs refers to reducing the crude protein level of the diet by 2-4 percentage points according to the recommended standard in the US "Pig Feeding Standards" (NRC, 1998), or according to the recommendation in my country's "Pig Feeding Standards" (Ministry of Agriculture, 2004). Standards have been lowered to varyi...
