Abstract

The invention relates to the technical field of a culture technology, in particular to a method for reducing the feed conversion ratio of fattening pigs. The method comprises the following steps of dividing the pig growth stage according to the body weight of the fattening pigs; regulating the fattening feed according to growth stages according to the following concrete measures that: feeding fattening No.1 feed when the body weight of the fattening pig is 20 to 35kg; feeding No.2 feed when the body weight of the fattening pig is 36 to 55kg; feeding No.3 feed when the body weight of the fattening pig is 56 to 75kg; feeding No.4 feed when the body weight of the fattening pig is 76 to 95kg; feeding No.5 feed when the body weight of the fattening pig is 96 to 115kg; feeding No.6 feed when thebody weight of the fattening pig is 116 to 130 kg. By using the method provided by the invention, the growth stage of the pig is reflected through the body weight change in the pig growth stage; theactive ingredient proportion in the feed is regulated according to different nutrition substances required by the pig in different growth stages. The feed conversion ratio of the fattening pigs is effectively reduced; the slaughtering pig quality is improved; the culture economic benefits are improved.

Description

【Technical field】 [0001] The invention relates to the field of breeding technology, in particular to a method for reducing the feed-to-meat ratio of fattening pigs. 【Background technique】 [0002] my country is a large pig-raising country with rich and colorful pig breed resources, which occupies an extremely important position in the world's pig production. Moreover, my country is also a big pork-consuming country. According to statistics, China's pork consumption is increasing year by year. Therefore, providing sufficient pork is very important for improving It is of great significance to improve people's living standards and maintain social stability and unity. The feeding of fattening pigs is one of the important links in pig production. The growth status of fattening pigs is directly related to the growth of the fattening period. High, easy to produce weaning syndrome of physiological dysfunction such as diarrhea and growth stagnation, which will cause death of piglets ...
