Problems solved by technology

The disadvantage is that the sows eat at the same time, the sows with strong physique will eat more, and the sows with weak physique will eat less, resulting in uneven feed intake among individual pigs, poor uniformity, and poor production performance of sows. to guarantee

Embodiment 1

[0030] The method for adjusting feed intake of sows during pregnancy is to add expandable cellulose raw material—beet pellet meal to the feed of pregnant sows, and the amount of beet pellet meal added is 3% of the total weight of the feed in terms of weight percentage.

Embodiment 2

[0032] The method for adjusting feed intake of sows during pregnancy is to add expandable cellulose raw material—beet pellet meal to the feed of pregnant sows, and the amount of beet pellet meal added is 6% of the total weight of the feed in terms of weight percentage.

Embodiment 3

[0034] The method for adjusting feed intake of sows during pregnancy is to add expandable cellulose raw material—beet pellet meal to the feed of pregnant sows, and the amount of sugar beet pellet meal is 4.5% of the total weight of the feed in terms of weight percentage.

Abstract

The invention discloses a food intake adjusting method for sows in a gestation period. An inflatable fiber raw material is added into feeds of sows in the gestation period. The method provided by the invention comprehensively utilizes advantages of other modes and overcomes the defect of a mode of limiting feeding through a physical isolation method. The food intake of a single sow is adjusted and controlled through a nutrition controlling technology under conditions of massive feeding and movement, the embryo death rate of sows in the gestation period is reduced, the litter size increases, and each sow has the best production performance.

Description

technical field [0001] The invention relates to the field of livestock breeding, in particular to a method for adjusting feed intake of sows during pregnancy. Background technique [0002] Sow feeding is the focus of pig raising, and the feed intake of pregnant sows directly affects the production performance of sows. Embryo death is the most serious in 1-3 days after mating of sows. If feeding is properly restricted within 7 days after mating (the feed intake is controlled at 50% to 60% of the free feed intake), embryo death can be reduced. Therefore, the feed intake of sows during pregnancy should be strictly controlled and adjusted. The breeding of modern industrialized pregnant sows adopts the method of restricting feeding to improve the production performance of sows. There are three ways to restrict feeding to pregnant sows: [0003] (1) Rearing in stalls. At present, countries with developed pig farming industries such as the United States, China, and Canada adopt...
