Problems solved by technology

The disadvantage of this method of rearing pigs is that the pigs are not completely isolated and the potential disease risk has not been purified through a sufficient isolation period. At the same time, this method of raising pigs directly into groups has not carried out disease-related antibody detection , if it carries infectious diseases, it will not

Embodiment Construction

[0029] The technical solution of the present invention is further defined below in conjunction with specific embodiments:

[0030] A gilt feeding management method that can improve sow performance is:

[0031] 1) isolation

[0032] Reduce the weight of the imported gilts to about 30kg, and then isolate and raise the gilts in the isolation house for 3 weeks. During this period, the antibody level of the gilts and the changes before and after isolation are comprehensively tested. It is required to introduce the blue-eared gilts The antibody s / p value is less than 0.2, and the blue ear antigen test is negative; the pseudorabies wild virus antibody s / n value is greater than 0.7.

[0033] The isolated shed is at least 100 meters away from the original pig herd to reduce the chance of infection of potential pathogens transmitted through the air. The gilts of the same batch are required to be all in and all out, and the facilities must be thoroughly washed and disinfected and kept d...

Abstract

The invention relates to a replacement gilt feeding management method capable of improving the production performance of a sow. The replacement gilt feeding management method is cooperatively implemented from aspects like isolation of a replacement gilt herd, taming, disease prevention and control, breed selection, housing environment control, feeding management and boar stimulation and estrus induction, significantly reduces the mortality risks of an introduced pig herd and a farm original pig herd, and improves the health degree of the pig herd, so the production performance of a reproductive sow is improved. The method provided by the invention comprises the following steps: 1) isolation; 2) taming; 3) replacement gilt selection; and 4) feeding management after the pig herd enters a replacement gilt house.

Description

1. Technical field: [0001] The invention relates to a feeding and management method for back-up pigs which can improve the production performance of sows. 2. Background technology: [0002] At present, my country's pig breeding is developing in the direction of scale, intensification, and industrialization, but there is a big gap between the production management and production level compared with the world's advanced level, and large-scale pig raising technology and management skills are lacking in some aspects , especially the management of back-up pigs. At present, the existing gilt breeding methods in my country are generally, the weight of the gilts is generally above 60kg, and they are directly fed into the gilts in the sow farm; The boar enters the gilt pen to induce love. The disadvantage of this method of rearing pigs is that the pigs are not completely isolated and the potential disease risk has not been purified through a sufficient isolation period. At the same t...
