Feeding method capable of improving local pork flavor of Guizhou and having epidemic prevention effect

Abstract

The invention provides a feeding method capable of improving local pork flavor of Guizhou and having an epidemic prevention effect. The feeding method comprises the following steps of (1) when the weight is less than 10 kg, feeding pigs with feed composed of the following components including 30-80 parts of garland chrysanthemum fermented dry powder, 20-30 parts of corn, 10-18 parts of soybean meal, 20-30 parts of bran, 0.1-0.2 part of an amino acid compound, 1-3 parts of calcium carbonate, 0.5-1 part of L-ferrous lactate, 0.5-1 part of beta-carotene and 0.2-0.3 part of salt; and (2) after theweight reaches 10 kg, feeding the pigs with a feed composed of the following components including 50-100 parts of garland chrysanthemum fermented dry powder, 80-100 parts of corn, 20-30 parts of bran, 10-15 parts of fish meal, 0.05-0.08 part of compound vitamins, 1-3 parts of cod-liver oil and 0.5-0.8 part of salt. The feeding method can significantly reduce the incidence of asthma and diarrhea and increase the intramuscular fat content.

Description

technical field [0001] The invention belongs to the technical field of livestock breeding, and in particular relates to a breeding method which improves the quality and flavor of Guizhou local pork and has the effect of preventing epidemics. Background technique [0002] Congjiang Fragrant Pig is a rare small local pig breed in my country that has been selected and cultivated by Congjiang ethnic minorities for a long time under specific natural environment and socio-economic conditions. It is a local superior germplasm resource in Guizhou Province. It is listed in the "National Livestock and Poultry Breed Resources Protection List" in Announcement No. 130, 2000. It has the characteristics of glutinous skin and meat, not greasy when eaten, and tender meat. [0003] One of the main production areas of Congjiang Fragrant Pigs is in Qiandongnan Prefecture, Guizhou Province. The industrialized breeding experience and technology of pig breeding in this area are insufficient, which ...

AI Technical Summary

Problems solved by technology

[0003] One of the main production areas of Congjiang Fragrant Pigs is in Qiandongnan Prefecture, Guizhou Province. The industrialized breeding experience and technology of pig breeding in this area are insufficient, which leads to asthma and diarrhea prone to occur during the breeding process, resulting in Economic losses

At present, there are still relatively few investigations and studies on asthma and diarrhea in Congjiang Xiang pigs. Please refer to "Epidemiological Investigation of Pig Asthma in Guizhou" (Yang Li, Wu Weiheng, Yang Maosheng, etc. Epidemiology of Guizhou Pig Asthma Investigation [J]. Shanghai Animal Husbandry and Veterinary Communication, 2016, 000 (004): 32-33.) and "Epidemiological Investigation of Guizhou Swine Diarrhea" (Yang Li, Xu Jinge, Yang Maosheng, et al. Epidemiology of Guizhou Swine Diarrhea Scientific survey [J]. Shanghai Animal Husbandry and Veterinary Communication, 2015, 000 (004): 58-58. It can be seen that how to prevent and treat asthma and diarrhea in Congjiangxiang pigs is an urgent problem to be solved

[0004] At the same time, limited by the level of breeding, there are relatively few studies on improving the quality and flavor of Congjiangxiang pork, which hinders the further marketing of Congjiangxiang pork
