Embodiment Construction

[0021] A breeding method for breeding pigs, comprising the steps of:

[0022] (1) Primary selection: when the weight is about 30kg, pigs with genetic defects, such as hernia, inverted nipples, irregularly arranged nipples, lock anus, cryptorchidism, etc., and pigs that do not conform to the appearance characteristics of this breed and poor growth and development are excluded;

[0023] (2) Second selection: carry out when the weight is about 60kg, and eliminate or deal with stunted and unqualified individuals;

[0024] (3) Three choices: Weigh once when the body weight is 85-105kg, as the final weight, and measure the body length, body height, hip width, chest width, backfat thickness and other data at the same time, according to the backfat thickness and growth rate, etc. Calculate the selection index of each pig, according to the level of the index, combined with blood relationship, body shape and appearance for on-site selection, select the high index and good body shape...

Abstract

The invention discloses a breeding method of breeding pigs, which comprises the following steps of: primary selection: excluding pigs which have the genetic defects, do not comfort to the appearance features and are poor in growth and development at the condition of 30 kg; secondary selection: carrying out elimination treatment or other treatments on individuals which are poor in development and are not qualified under the condition of 60 kg; tertiary selection: calculating the selection index of each pig according to the backfat thickness, the growth speed and other data, carrying out site selection according to high and low indexes and in combination with the blood relationship and the body type appearance and selecting pigs with high indexes and good body type appearance into a core group; starting to mate after the weights and the month ages of gilts subjected to the tertiary selection reach the standard; and carrying out semen examination and limb and hoof compactness evaluation on boars selected by final detection before mating and eliminating the boars which are not qualified in the continuous tertiary semen examination. The breeding pigs bred by adopting the method disclosed by the invention have the advantages of high pig fecundity and quick weight-increasing speed and are very suitable for being raised and reproduced by various farming village farmers.

Description

technical field [0001] The invention relates to a new variety of vertebrates, in particular to a breeding method for breeding pigs. Background technique [0002] The essence of breeding pigs is to decide which pigs to breed and how to breed between them, and the basis of breeding is mainly the results of field measurements. Breeding traits should be aimed at maximizing economic benefits. During the breeding process, traits with high heritability or higher traits should be considered as target traits. Different developmental stages should focus on selecting different traits. Male pigs and sows should be Develop different selection criteria. Although there are some introductions about breeding pigs at present, they are only scattered and not systematic enough. In addition, there are no patent applications related to breeding pigs in China. Contents of the invention [0003] The purpose of the present invention is to provide a breeding method for breeding pigs a...
