Problems solved by technology

However, this technology has certain limitations. The proportion of aged corn in the diet and the degree of oxidation of aged corn will affect the effect of antioxidants.
In addition, the existing tests and feed formulation techniques for preventing pig yellow fat are concentrated in the fattening stage, but our experiments show that the appearance of pig yellow fat has a cumulative effect, and once yellow fat is formed, it is difficult to eliminate. Take preventative techniques early

Abstract

The invention discloses a compound premixed feed for solving the yellow fat meat problem of pigs and a preparation method thereof. The compound premixed feed comprises lysine, methionine, threonine, tryptophan, calcium hydrophosphate, compound trace elements, compound vitamins, tert-butylhydroquinone, 50% choline chloride, table salt and stone powder. The method comprises the following steps: (1)mixing vitamin A, vitamin B1, vitamin B2, vitamin B12, vitamin D3, vitamin E, vitamin K, zeolite powder and rice chaff to obtain a master batch A; (2) mixing the lysine, the methionine, the threonine,the tryptophan, the calcium hydrophosphate, the tBHQ, the 50% choline chloride, the table salt, copper sulfate, ferrous sulfate, zinc sulfate, manganese sulfate, 1% potassium iodate, 1% sodium selenite and the stone powder to obtain a master batch B; and (3) mixing the master batch A and the master batch B in proportion, wherein the variable coefficient of mixing uniformity is not higher than 7%.The compound premixed feed is reasonable in formula and convenient to use, effectively prevents the yellow fat meat of pigs, reduces the feed conversion ratio, and improves the economic benefit.

Description

technical field [0001] The invention belongs to the field of animal nutrition and feed science and technology, and more specifically relates to a compound premixed feed that solves the problem of pig yellow fat, and also relates to a preparation method of the compound premix feed that solves the problem of pig yellow fat. Background technique [0002] In recent years, with the intensification of pig breeding, there is an ultra-high level or unbalanced nutrient supply in production, which leads to clusters of nutritional and metabolic diseases. Pig yellow fat is the yellow staining of the subcutaneous fat of fattening pigs after slaughter, which seriously affects the appearance and selling price of pork, and the slaughter rate of yellow fat pig carcasses is significantly reduced, which brings major economic losses to breeding enterprises. [0003] Pig yellow fat is also known as nutritional panniculitis, which is characterized by inflammation of adipose tissue and waxy pigmen...
