Piglet feeding method

Abstract

The invention relates to a piglet feeding method, which comprises the feeding technology in two stages including pig breed selection and feeding management. Dongsa aardvark pigs growing in plateau snow mountain regions in Yunnan are selected to be used as pig breeds. The feeding management comprises the following factors that a, feed consists of the following ingredients in percentage by weight: at least 66 percent of corn, at least 22 percent of soybean meal and at most 12 percent of Diyi feed, and energy feed with the crude protein reaching 17.74 is formed; and after the materials are uniformly mixed, the piglets eat the feed according to the self appetite; and b, the piglets are managed according to the following method in the ordinary time activities: weaned piglets are divided into groups, pig houses are subjected to ventilation, heat insulation and sterilization, and the works of immunization, disease prevention and the like are carried out at proper time. The health growth of the Dongsa aardvark piglets at the later growth period is maintained, and the pork quality, the nutrition value and the fresh and delicious mouth feeling are ensured. The raising time of the Dongsa aardvark piglets after being converted to the fattening period is shortened from more than one year of the traditional feeding method to 8 to 9 months. Good pork is provided for customers, so the quality of Xuanwei ham with long history is hopeful to be recovered and developed.

Description

technical field [0001] The invention relates to a piglet feeding method. Background technique [0002] The pigs raised in most large-scale farms are mostly foreign breeds (Duroc, York, Changbai), and the pigs are fed after the ratio of concentrated feed and energy feed. No green feed is added, and they are not resistant to rough feeding. The protein content of the feed is required. High, the comprehensiveness of wild feeding is poor, and the disease antibody is not strong, it is easy to be attacked by viruses, and the fattening period is 6-7 months. Without the form of natural stocking, the growth rate of pigs is fast, the growth cycle is short, and the lean meat rate is high, but the intermuscular fat content is not moderate, and it does not have the tender and moist meat quality of local Dongsa soil pigs. As a result, the composition of the pork is a structure with a clear boundary between lean meat and fat meat, resulting in high fat content in the fat meat, and there is...

Problems solved by technology

[0003] The purpose of the present invention is to provide a piglet feeding method to solve the problems of slow growth and fattening cycle of 12-15 months in the original feeding method of Dongsa pigs, resulting in high breeding costs and relatively poor economic benefits
