Embodiment Construction

[0015] There are certain differences between the breeding methods of Dongchuan pigs and ordinary pigs. The following adopts different feeding methods for each stage. Each stage includes the selection and cultivation stage of Dongchuan pigs, pregnancy stage, postpartum stage, piglet nursery stage, The rearing stage and fattening stage, feeding methods including feeding feed, epidemic prevention measures, and pigpen selection are explained in detail.

[0016] (1) In the stage of seed selection and breeding, when selecting mating pigs, select boars with excellent reproductive organs, and the effective teats of breeding sows must reach more than 8 pairs. Breeding pigs are fed once a day in the morning and in the afternoon. Each boar is fed about 1,300 grams of feed, and the ingredients are 50% corn, 20% wheat bran, 15% soybean meal, 12% hay powder, 2% fish meal and 1 salt. %, of which 12% hay powder ingredients are grain amaranth 2%, Russian feed vegetable 2%, bitter pickle 2%, ry...

Abstract

The invention discloses a breeding method of Dongchuan pigs. The method comprises a selective breeding stage of Dongchuan pigs, a pregnant stage, an after-delivery stage, a piglet nursing stage, a growing period stage and a fattening period stage; in all stages, different feeding modes are adopted for feeding; the feeding modes comprise batching of feed, anti-epidemic measures and piggery selection. The Dongchuan pigs bred through the method are strong in disease resistance, high in growth rate, high in survival rate of piglets, and low in culturing cost.

Description

technical field [0001] The invention relates to the technical field of pig raising, in particular to a breeding method for Dongchuan pigs. Background technique [0002] Historically, there were Jiangquhai pigs in the north of Jiangsu Province, Erhualian pigs in the south, Zao pigs in the northeast, and Mi pigs in the southwest. In addition, the frequent exchange of breeding pigs in this area made the source of Dongchuan pigs quite complicated. According to many surveys, it is believed that Dongchuan pigs are formed by long-term selection and breeding of the above-mentioned local pig breeds. At present, this breed of pigs has been included in the protection list of livestock and poultry genetic resources in Jiangsu Province. However, due to its slow growth rate and low feed remuneration, Dongchuan pigs are not widely raised in society. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for cultivating Dongchuan ...
