Six-stage nutritional complete feed for breeding sows and feeding method

Abstract

The invention relates to the technical field of complete feed for breeding sows, in particular to six-stage nutritional complete feed for the breeding sows and a feeding method. According to the characteristics of parturition period of the breeding sows, the parturition period of the breeding sows is divided into six stages through combination of physiological characteristics and nutritional requirements of the breeding sows in theparturition period, the breeding sows are fed with different kinds of nutritional feed according to the six stages, the feeding process is studied, so that the nutrients in the six stages have cooperative interaction and are supplementary, mammary gland development of the breeding sows is promoted, milk yield is increased, appetite of the breeding sows is improved, food-intake is improved, oestrus times and ovulation times in the non-pregnant period are increased, dystocia rate of the breeding sows is reduced, the whole parturition of the breeding sows is shortened, and quick postpartum recovery of body condition of the breeding sows is facilitated.

Description

technical field [0001] The invention relates to the technical field of complete feed for sows, in particular to a six-stage nutritional complete feed for sows and a feeding method. Background technique [0002] The sow is the core link of pig breeding. The reproductive capacity of the sow is related to the scale of the pig farm and the cost of breeding; a production cycle of a sow includes the early pregnancy, the middle pregnancy, the late pregnancy, the lactation period, and the empty pregnancy period. The middle and late stages of pregnancy are about 114 days, the lactation period is about 24 days, and the empty period is about 7 days, that is, a production cycle is about 145 days in total, and there are different physiological changes in different periods, and its energy and nutritional requirements There are also differences. [0003] At present, in the prior art, during a production cycle of sows, a "sow two-stage nutrition and feeding mode" is adopted, that is, the s...

AI Technical Summary

Problems solved by technology

[0006] It can be seen that in the prior art, during the whole production cycle of the sow, the nutritional feed of each stage has been studied. However, in the prior art, the interaction between each stage of the sow's production cycle Considering the combination of these factors, the research on the interaction between the nutrient feed input at each stage of the sow and the interaction of other stages makes the nutrient supply in the whole production cycle of the sow unsatisfactory, and the improvement of the reproductive performance of the sow is not satisfactory. Ideal, sow farrowing health and litter size are not ideal
