Method for raising pigs which are raw materials for dried pork

Abstract

The invention discloses a method for raising pigs which are raw materials for dried pork. The method includes selecting three-breed hybrid pigs of large Yorkshire pigs, Landrace pigs and Dahe black pigs to be used as pig breeds; feeding piglets according to conventional processes until the weights of the piglets reach 25 kg; feeding the piglets at small, medium and large phases until the weights of the piglets reach 160 kilograms and then slaughtering the pigs. The feeding periods range from 270 days to 300 days under the control, antibiotics are replaced with Chinese herbal medicine additivesin the three feeding phases, partial corn is replaced with barley and konjac fly powder, the backfat thicknesses and deposition of abdominal fat of the pigs are reduced, the firmness of pork is improved, and the melting point of fat of the pork is increased. The method has the advantages that air-dried fermented pork processed from the pork is good in water-holding capacity and high in fat firmness and melting point, and oil seeping of finished products can be prevented; the pork has obvious marble veins, contains a large quantity of intra-muscular fat and is high in dry matter content, and the finished products have sufficient flavor; medicine residues are prevented; the method has good economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of pig breeding methods, in particular to a method for raising pigs as a dried pork raw material. Background technique [0002] Fermented meat products refer to a type of meat products with special flavor, color and texture, and a long shelf life after the fermentation of livestock and poultry meat inoculated with beneficial microorganisms under natural and artificially controlled environmental conditions, mainly including fermented sausages and fermented meat products. There are two types of ham, and dry-cured hams such as Jinhua ham and Xuanwei ham in my country also belong to this type of product. Livestock and poultry meat is fermented by beneficial microorganisms, which increases the activity of enzymes in the meat. Proteins and fats produce a large number of active factors under the action of enzymes, and at the same time produce a large number of amino acids, ketones, aldehydes, alcohols, hydrocarbons ...

Problems solved by technology

The cost of barley peeling for feed breeding is relatively high, and some broken grains are produced, which leads to problems such as inconvenient storage, nutrient oxidation loss, and mold growth.
