Feed additive for preventing pig yellow fat meat

Abstract

The present invention discloses a feed additive for preventing pig yellow fat meat. The feed additive is composed of the following components in mass percentages: 15-30% of vitamin C, 1-4% of sodium selenite, 5-15% of dibutylhydroxytoluene and the balance olive meal. The feed additive can effectively remove oxygen free radicals generated in feeds and pig bodies, improves body's antioxidant capacity, prevents lipid peroxidation and deposition of ceroid pigment in pig adipose tissues, and prevents occurrence of the yellow fat meat.

Description

technical field [0001] The invention relates to a feed additive for preventing pig yellow fat and belongs to the technical field of animal nutrition and feed science. Background technique [0002] In my country's pig production, especially in the southern region, the fat of pork carcasses often turns yellow. This kind of pork is generally called yellow fat meat. Yellow fat meat is difficult to find through inspection and quarantine before slaughtering. Once it occurs, it is usually not edible and has no sales value, which has brought huge economic losses to feed, pig breeding and slaughtering enterprises. [0003] Yellow fat meat, also known as yellow fat disease, nutritional adipose tissue inflammation or nutritional panniculitis, is characterized by obvious inflammation of adipose tissue and deposition of "waxy" pigment in fat cells. Studies have shown that the cause of yellow fat meat is mainly due to the high content of unsaturated fatty acids and insufficient antioxida...
