Problems solved by technology

[0003] The purpose of the present invention is to establish a hybrid offspring of breeding domestic pig and wild boar, so that this offspring combines the length of domestic pig and wild boar and shows better heterosis. High, adaptable, strong game, and can overcome the seasonal estrus of wild boar, less litter and difficult to raise, so that it can reproduce and raise normally, and then provide green, pollution-free, delicious meat, low-fat, nutritious Meat products with high content

Embodiment 1

[0025] 1. Feeding and management of males, sows and piglets:

[0026] (1) Breeding and management of boars

[0027] It is difficult to catch and raise wild boars. The current level of survival rate can only reach 10%, and there are very few wild boars that can be used for breeding. high. 1. Larger housing area, at least 7 square meters. The pens are clean and hygienic, dry and warm, without strong wind. 2. Prepare suitable feed for boars. The feeding amount of wild boars and wild hybrid pigs is only two-thirds of that of domestic pigs, so the feed must contain sufficient nutrients, and the proportion of green feed is relatively higher. 3. Wild boars are lively in nature and require a lot of exercise. Ensure that boars have strong libido, maintain normal physiological metabolism of breeding boars, and improve the quantity and quality of semen. 4. Reasonable utilization. The mating of boars should be planned. During the entire use period of boars, the mating time is 12-14 m...

Abstract

The invention discloses a crossing breeding and feeding method of wild boars, domestic pigs and hybrid pigs. The wild boars are not fit for feeding and popularization for the reasons that the number of the wild boars is limited, the meat is not fine and the skin is thick, and mouthfeel is worse. The wild boars are oestrous seasonably, produce fewer piglets, and are not easy to feed wild boars. However, the interest of people of pursuing venison and changing taste is increasing. The method for domesticating wild boars is a task that people pay attention to. The method includes: choosing long and white sows or big and white sows, carrying out crossing breeding through crossing generation I, backcrossing generation II, horizontal crossing generation I, and side crossing generation II of the sows and wild boars, total 6 generations. 12-16 months are required for one generation; or choosing duroc sows, carrying out crossing breeding through crossing generation I, backcrossing generation I, horizontal crossing generation II within lines, and horizontal crossing generation III among lines of the duroc sows and wild boars, total 7 generations, 12-14 months are required for each generation. The crossing breeding and feeding method of wild boars is used for crossing breeding and feeding.

Description

Technical field: [0001] The invention relates to a method for improving wild boar hybridization. Background technique: [0002] The number of wild boars is limited, the meat is thick and the skin is thick, and the taste of the meat is poor. It is not suitable for simple domestication and promotion. Moreover, wild boars are in estrus seasonally, with few litters and difficult to raise. And there is a growing interest in seeking game and improving taste. The domestication of wild boars has become a subject of widespread concern. Invention content: [0003] The purpose of the present invention is to establish a hybrid offspring of breeding domestic pig and wild boar, so that the offspring can combine the length of domestic pig and wild boar and show better heterosis. High, adaptable, strong game, and can overcome the seasonal estrus of wild boar, less litter and difficult to raise, so that it can reproduce and raise normally, and then provide green, pollution-free, deliciou...
