Pig feed

Abstract

The invention belongs to the technical field of livestock feed and discloses pig feed. The pig feed is prepared from the following components in percentage by mass: 20 percent of fish meal, 20 percent of soybean meal, 10 percent of rapeseed meal, 20 percent of bran, 10 percent of corn flour, 8 percent of catharanthus roseus, 8 percent of vitamin E, 2 percent of table salts, 1 percent of citric acid, 0.5 percent of proteinase preparation and 0.5 percent of trace element additive. The pig feed disclosed by the invention also contains 8 percent of the catharanthus roseus to serve as green forage; vincaleukoblastinum is contained in the catharanthus roseus, is used as plant alkaloids, and can act in a pig body for inhibiting polymerization of microtubulin, hindering the forming of spindle microtubule and promoting hair removal of pigs at a large amount; in addition, by using 2 percent of the table salts, the salts can cause retention of water in a pig body, and the retained water influences the growth of pig hairs; the table salts simultaneously induce the accumulation of multiple oil, and aggravate the hair removal phenomenon; finally, the vincaleukoblastinum and table salt molecules interact to aggravate hair removal of the pigs, so that a large amount of hairs are removed in a feeding process of the pigs, and the amount of pig hairs is reduced; during leather production, residual pig hairs can be removed by one-time hair removal, so that the damage probability of pig skin is reduced.

Description

technical field [0001] The invention belongs to the technical field of livestock feed. Background technique [0002] Pig leather products have become the most widely used type of leather because of their low price and durability. Pig skin, the raw material of pig leather products, is obtained by: killing pigs with high-voltage electric shock (to maintain the integrity of pig skin) - plucking - peeling - salt preservation. When plucking, use molten hot rosin pouring (after it condenses, crush the rosin to complete the plucking) or a razor, but because there are many hairs on the pigskin, no matter what method is used, it needs to be repeatedly plucked. The operation can be removed, and in the process of repeated plucking, it will cause damage to the surface of the pigskin. For example, the razor will produce scratches, and the hot rosin will cause the surface of the pigskin to shrink and wrinkle, which will eventually reduce the pigskin. The quality of pig leather products ...

Problems solved by technology

When plucking, use molten hot rosin pouring (after it condenses, crush the rosin to complete the plucking) or a razor, but because there are many hairs on the pigskin, no matter what method is used, it needs to be repeatedly plucked. The operation can be removed, and in the process of repeated plucking, it will cause damage to the surface of the pigskin. For example, the razor will produce scratches, and the hot rosin will cause the surface of the pigskin to shrink and wrinkle, which will eventually reduce the pigskin. The quality of pig leather products is poor

[0003] At present, the pig feeds on the market are all designed to increase lean meat content, improve piglet immunity or milk production of lactating sows, etc., and do not specifically configure feed for leather products, and control pig hair from the pig raising process. As a result, all the raw material pigs have strong hair, and finally go through repeated hair removal operations, which affects the quality of leather products
