Abstract

The invention discloses a high-efficiency breed conservation and quality conservation method for local well-bred pigs. In order to overcome the defects that the hybridization of the local well-bred pigs overruns at present, the loss of hereditary characters is serious, the quality drops, the breed conservation and quality conservation input is high, the cost is high and effect and benefit are poor, the high-efficiency breed conservation and quality conservation method disclosed by the invention comprises the steps that a center ethnic group is established in a center ethnic group region of a core origin of the local well-bred pigs, periphery ethnic groups are established outside the center ethnic group, and further, a foundation origin ethnic group is formed; all the ethnic groups are fed according to similar conditions of more than 50 percent of mainstream farmers of the origin of the ethnic groups; piglets delivered through mating of sows of all the periphery ethnic groups and boars of the center ethnic group are used as commodity piglets. According to the high-efficiency breed conservation and quality conservation method for the local well-bred pigs, disclosed by the invention, not only can the purity and the fine quality of the local well-bred pigs be effectively protected, so that the quality of pork returns to a due level, the effect and the benefit of reasonable hybridization utilization are reasonably embodied, but also implementation is simple and convenient; the breed conservation and quality conservation cost is reduced by more than 70 percent, and the benefit is increased by more than 50 percent.

Description

The efficient conservation keeping method of local breeding pig

Technical field

The present invention relates to the seed selection feeding method of a boar, be specially the efficient conservation keeping method of a kind of local breeding pig.

Background technology

Along with the judicial convenience of traffic, the abuse of cross method and the excessive pursuit to economic interests, existing Local Excellent pig kind is degenerated serious, and quality declines, and makes pork there is no the peat-reek of pork; And because each Local Excellent pig kind purity declines seriously, make reasonably hybridization utilize choosing less than father, the female parent with qualified purity, and to hybridize and utilize advantage to decline, the benefit of raising pigs is had a strong impact on.

But the method for carrying out the raising of fine-variety breeding conservation according to existing system not only has high input, cost is high, and effect efficiency is poor, does not usually reach set objective, and even population reduces extinction gradually, causes the loss that is difficult to make up.

Summary of the invention

Object of the present invention is exactly will be for above-mentioned deficiency; provide a kind of local breeding pig efficient conservation keeping method; it not only can effectively protect purity and the fine quality of local breeding pig; make meat quality return due level, make reasonably hybridization utilize effect, benefit rationally to be embodied, and be easy to implement; cost is low; definite effect, profitable, easily reach the target that conservation is guaranteed the quality.

For achieving the above object, technical scheme of the present invention is that the efficient conservation keeping method of this place breeding pig is:

A. using the region of 50 kilometers of local breeding pig core place of production circumferences as district of group, center, select at least 30 farmers''s soil to support pure local breeding pig and set up center group in district of group, Gai center, You Gai center group area edge outwards extends 50 kilometers and produces above extension boundary line, district of outer rim group, You center group area edge, extension boundary line, district of Liang Tiao outer rim group, and the district of outer rim group that forms of the above outer rim width of 70 kilometers of width, select at least 30 farmers''s soil to support pure local breeding pig and set up outer rim group, so set up 4 outer rim groups, together with the group of described center, form basic original seed group, superseded samsara in 3 years (is that every 3 years each groups all eliminate, again select the basic original seed of composition group from above-mentioned regional), the piglet that the piglet in above-mentioned each district of group produces from the sow of each outer rim group and the boar mating of center group,

B. each group feeds according to the condition of similarity of its original producton location 50% above main flow peasant household;

C. center group is from numerous manufacturer's product stock boar, and outer rim group is from numerous manufacturer's product breeding sow;

D. the boar pig that mating is farrowed of the sow of each outer rim group and center group is as commodity piglet;

E. the commodity piglet of described steps d adopts the health of farmers' soil to grow to after 50 kilograms, adopts pigweed 70%, corn or/and paddy 15%, dregs of beans are delivered body weight for sale or/and animal flesh bone meal 15% is raised to market pig.

The present invention is using the region of 50 kilometers of local breeding pig core place of production circumferences as district of group, center, center group is selected to set up by district of group, Gai center, the district of outer rim group that You center group area edge, the 50 kilometers of above extension boundary lines, district of Liang Tiao outer rim group that extend and 70 kilometers of above outer rim width of width form, outer rim group is set up in selection, so set up 4 outer rim groups, together with the group of center, form basic original seed group, superseded samsara in 3 years.This basis original seed group can be dispersed in each district of group and lay foundations, and also can concentrate and lay foundations.Basis and the natural ecological environment condition that forms in conjunction with local breeding pig are carried out conservation and are guaranteed the quality like this, not only each group is built on the rock, wide in range, be full of vitality, conservation preservation and effect is good, efficiency is high, remarkable benefit, and take full advantage of the existing natural ecological environment condition of local breeding pig, the science of conservation strengthens, make reasonably hybridization utilize effect, benefit is rationally embodied, safety improves, can be due to the destruction of the entire PLA of epidemic disease Deng Shi group, especially the cost that conservation is guaranteed the quality reduces greatly, the conservation of local breeding pig is guaranteed the quality to drop into and is greatly reduced, social and economic benefits and good.

Center group is from numerous manufacturer's product stock boar, and outer rim group is from numerous manufacturer's product breeding sow,

The boar pig that mating is farrowed of the sow of each outer rim group and center group is as commodity piglet, each group feeds according to the condition of similarity of its original producton location 50% above main flow peasant household, commodity piglet adopts the health of farmers' soil to grow to after 50 kilograms, adopts pigweed 70%, corn or/and paddy 15%, dregs of beans are delivered body weight for sale or/and animal flesh bone meal 15% is raised to market pig.Can effectively ensure like this genetic stability of local breeding pig, improve the effect that conservation is guaranteed the quality, can make again adaptability of the present invention strengthen, especially can significantly reduce local breeding pig conservation feeding cost, local breeding pork be returned and there is due fragrance.

The present invention can be widely used in the efficient conservation of local breeding pig and guarantee the quality; not only can effectively protect purity and the fine quality of local breeding pig; make meat quality return due level; make reasonably hybridization utilize effect, benefit rationally to be embodied, and be easy to implement, experimental result shows; cost of the present invention is low more than 70%; definite effect, benefit improves more than 50%, can reach with comparalive ease the target that conservation is guaranteed the quality.
