Ecological breeding method of South Anhui spotted pigs

Abstract

An ecological breeding method of South Anhui spotted pigs comprises the steps as follows: S1, two pigsties are arranged for each South Anhui spotted pig and communicated through an isolation passage,and bells are arranged on the pigsties; S2, when the South Anhui spotted pig is in one pigsty, feed is put in a trough of the other corresponding pigsty and the bell in the pigsty makes sound; the South Anhui spotted pig is driven to enter the other corresponding pigsty to eat, and belling is stopped until the South Anhui spotted pig enters the other corresponding pigsty to eat; S3, after the South Anhui spotted pig eats up all feed in the other corresponding pigsty, feed is put in a trough of one pigsty and the bell in the pigsty makes sound, the South Anhui spotted pig is driven to enter thepigsty to eat, and belling is stopped until the South Anhui spotted pig enters the pigsty to eat; S4, the S2 and the S3 are repeated until the South Anhui spotted pig produces conditioned reflex to eat automatically. With the adoption of the method, the South Anhui spotted pigs can be promoted to eat and the growth speed can be further increased; meanwhile, lean meat production is promoted and the pork quality is improved.

Description

technical field [0001] The invention relates to the technical field of pig breeding, in particular to an ecological breeding method for southern Anhui colored pigs. Background technique [0002] Wannan flower pig is one of the famous local breeds in Anhui Province, mainly distributed in the south of Huangshan Mountain and the upper reaches of Xin'an River in southern Anhui.

Problems solved by technology

On the one hand, due to the small space in the pig shed, the pigs lack exercise, and most of the pigs are fat, and the meat quality is poor and the taste is poor

On the other hand, due to the excessive consumption of pig feed by adult pigs, excessive hormones and chemical residues remain in the body, posing a threat to human health
