Replacement gilt feeding management method capable of improving production performance of sow

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...

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 only affect the health of gilts and subsequent production performance, but also pose a threat to the health of the original herd; the contact between boars and sows is late, and the number of contacts is limited. The sexual maturity and normal reproductive rhythm of gilts cannot be guaranteed, thus affecting the life-long production performance of sows
