Loose breeding method for black pigs

Abstract

The invention belongs to the technical field of pig breeding, and discloses a loose breeding method for black pigs, which includes the following steps: (1) planting Fongtang plum trees in a breeding farm; arranging a pigsty outside the breeding farm, and arranging a door in the pigsty to communicate with the breeding farm; (2) selecting weaned young pigs, feeding a special feed for the young pigsin the pigsty, feeding the special feed 3-4 times a day with 200-250 grams each time for each suckling pig, feeding a glucose aqueous solution 1-2 times a day, and feeding distilled water after 5-7 days; for young pigs of 1-3 months, feeding the special feed 5-6 times a day with 1000-1250 grams per suckling pig each time, feeding a vitamin C aqueous solution 1-2 times a day, and feeding distilledwater after 5-7 days; (3) driving adult pigs for more than 3 months to the breeding farm for stocking, and supplementing concentrated feed and green feed during stocking; and (4) pigsty management. The method effectively improves the stress capability of the black pigs to the environment, enhances the physique of the black pigs, effectively improves the self resistance of the black pigs and ensures the health of the black pigs.

Problems solved by technology

[0003] However, in the existing technology, the breeding methods of black pigs generally have problems such as extensive management, single feed, low immunity, slow growth period, and low body weight. In order to maximize economic benefits, some pig farms use feed added with antibiotics to prevent certain These diseases cause drug residues and environmental pollution, which seriously threaten the health of the people
