Method for ecological breeding of Tibetan pigs

Abstract

The invention relates to the technical field of animal husbandry, and provides a method for ecological breeding of Tibetan pigs. The method includes the steps that mountainous grassland with lush green grass is selected to serve as a playground type grazing region, perennial herbaceous plants are mixedly sown and planted on the grassland, and then various kinds of forage are mixedly sown every year after; an ecological pig house is built, silage forage and the like are manufactured, during breeding, one or more of oat, cyperus esculentus, grassiness, chicories, alfalfa, the silage forage and natural weeds are supplemented to the pig house irregularly, and after the pigs freely eat, the pigs are driven into a playground for short-time grazing. By planting various kinds of forage in the playground, more than 100 commercial pigs can be bred on each mu of playground grassland, and large-scale ecological breeding is achieved. According to the method, a modern bioengineering breeding mode isused for disease control, and natural raw materials are used for supplementing microelements to improve the immunity and disease resistance of the pigs; protein raw materials and vitamins are provided for the pigs through manually planted forage, so that large-scale ecological breeding of the Tibetan pigs is achieved.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry and relates to a method for raising Tibetan-fragrant pigs, in particular to a method for large-scale ecological breeding of Tibetan-fragrant pigs. Background technique [0002] With the continuous increase of breeding density in modern large-scale pig breeding, the incidence of pig disease is high. In order to reduce the incidence of pigs and increase the growth rate, many farms will use chemical drugs, chemical hormones, and chemical additives during the breeding process. In the selection of feed, high-energy and high-protein compound feeds are often used. As for the breeds of pigs, the breeds with fast growth such as Landrace pigs, Large White pigs, and Duroc pigs imported from abroad are often used in the market. Their hybrid offspring, resulting in poor quality pork, poor taste, high drug residues. Moreover, in the breeding process, a large amount of feces and urine pollution are cau...

[0002] With the continuous increase of breeding density in modern large-scale pig breeding, the incidence of pig disease is high. In order to reduce the incidence of pigs and increase the growth rate, many farms will use chemical drugs, chemical hormones, and chemical additives during the breeding process. In the selection of feed, high-energy and high-protein compound feeds are often used. As for the breeds of pigs, the breeds with fast growth such as Landrace pigs, Large White pigs, and Duroc pigs imported from abroad are often used in the market. Their hybrid offspring, resulting in poor pork quality, poor taste, and high drug residues

Moreover, in the breeding process, a large amount of feces and urine pollution are caused by over-intensive feeding, which directly threatens the ecological environment and human health, and consumes a large amount of food.

It has not yet been seen that there is no use of chemical drugs, chemical additives and full-price feed, and no pollutants such as feces and urine are produced during the breeding process, so that zero pollution and zero emissions are achieved, and a kind of easy-to-manage, rough-feeding-resistant, Breeding methods for new breeds of meat pigs with strong disease resistance, good meat quality and high reproductive rate
