Feed for improving lean meat factor of fattening pig and preparation method of feed

Abstract

The invention relates to a feed for improving the lean meat factor of a fattening pig. The feed for improving the lean meat factor of the fattening pig comprises the following materials: bean pulp, corn, peanut meal, bran, mountain flour, calcium bicarbonate, antioxidant, compound vitamin, compound microelement, salt, lysine and traditional Chinese medicine additive, wherein the traditional Chinese medicine additive comprises the following bulk drugs: astragalus mongholicus, medlar, poria cocos, herba epimedii, hawthorn, fennel, codonopsis pilosula, pericarpium citri reticulatae, ligusticum wallichii, liquorice, malt, rhizome atractylodis, quispualis indica, radix achyranthis bidentatae and dandelion. By adopting a new formula and the traditional Chinese medicine additive, the nutritional requirement of the fattening pigs is met, the palatability is good, the growth rate of lean-meat-type fattening pigs is high, the lean meat factor is high, the body type is plump, the anti-stress capability is strong, the meat is bright-colored and the drip loss is low. Besides, the feed has the advantages of little toxic and side effect, no drug tolerance, no residue and the like, and the side effect on the food safety is reduced.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to a feed for fattening pigs, in particular to a Chinese herbal medicine feed for increasing the lean meat percentage of fattening pigs and a preparation method thereof.

Problems solved by technology

[0003] There are mainly the following ways to improve the lean meat rate of pigs: First, the selection of lean meat-type strains or specialized strains is a fundamental measure, but it takes a long time

Second, appropriately reduce the slaughter weight of commercial pigs, which will affect the economic value of live pigs

However, the use of clenbuterol has brought about two major problems: one is that the incidence of PSE meat and DFD meat in pork increases, and the quality decreases; Animal food containing residues can be poisonous and life-threatening if ingested in large quantities

Although some studies on the application effect of Chinese herbal medicine additives in pig production have been carried out at home and abroad, they mainly focus on the effects of pig growth performance and the digestion and absorption of nutrients in feed. Less research has been done on its quality
