Precise feeding method for pregnant pigs in large pigsty

Abstract

The invention discloses an accurate feeding method for pregnant pigs in a large pigsty. The method comprises the following steps: 1, conducting management in a gestation period; 2, blending feed in the gestation period; 3, feeding with feed in the gestation period; 4, separating fat and thin pigs in different pigsties; 5, preparing feed in the perinatal period; and 6, feeding feed in the perinatal period. Compared with an existing pregnant pig feeding method, a one-time feeding method is adopted, individuals with poor body conditions conduct secondary ingestion on residual feed, even if food grabbing occurs, it can be ensured that each pig can be full, adjustment and management of backfat are achieved, meanwhile, the hardware input cost is reduced, according to the method, the pigsty separating management is carried out according to the backfat condition of the pregnant pigs, the daily feeding amount is reasonably planned, so that the pregnant pigs are prevented from being too fat or too thin, feed supply with different contents of nutritional ingredients is implemented according to the pregnancy requirements of the pregnant pigs in different periods, the dystocia rate of sows is reduced, and the newborn vitality of piglets is improved.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to a precision feeding method for large pens of pregnant pigs. Background technique [0002] In the process of large-scale pig raising, the feeding of pregnant pigs is the key factor that determines the survival rate of piglets. The feed intake of pregnant pigs will change in real time from the labor stage to the delivery stage, so precise feeding is required. Existing Most of the feeding methods for pregnant pigs are automatic feeding. Automatic feeding is to code each pregnant pig, then set the corresponding feeding amount, and then use the code reader to read the code for feeding, but if you use a If the feeder feeds multiple pregnant pigs, the pregnant pigs will compete for food, and it is still impossible to achieve precise feeding. If a pig is fed separately with a feeder, the hardware input cost will be greatly increased; The feeding of existing pregnant pigs has not been ...

[0002] In the process of large-scale pig raising, the feeding of pregnant pigs is the key factor that determines the survival rate of piglets. The feed intake of pregnant pigs will change in real time from the labor stage to the delivery stage, so precise feeding is required. Existing Most of the feeding methods for pregnant pigs are automatic feeding. Automatic feeding is to code each pregnant pig, then set the corresponding feeding amount, and then use the code reader to read the code for feeding, but if you use a If the feeder feeds multiple pregnant pigs, the pregnant pigs will compete for food, and it is still impossible to achieve precise feeding. If a pig is fed separately with a feeder, the hardware input cost will be greatly increased; The feeding of existing pregnant pigs has not been reasonably adjusted according to the backfat status of sows, which may easily lead to overfat or underweight sows and affect the survival rate of piglets; the feeding of existing pregnant pigs does not meet the pregnancy needs of different periods, The implementation of feed supply with different content of nutrients can easily lead to high dystocia rate of sows and weak newborn vigor of piglets
