Feeding management method of sows

Abstract

The invention discloses a feeding method of pigs, and particularly discloses a feeding management method of sows. The feeding management method of the sows comprises the step of feeding management on four stages of replacement gilts, non-pregnant and breeding sows, pregnant sows and farrowing and lactation sows. The protein level of the sows keeps 16%; the feeding amount is increased or decreased in time according to the weights of the replacement gilts; every 4-6 non-pregnant and breeding sows stay in one sty to be fed, and the sows are bred in time; the feeding amount of the pregnant sows is adjusted according to the early pregnancy stage, the middle pregnancy stage and the later pregnancy stage, namely the weights of the sows; delivery rooms, delivery beds and the sties are sterilized before the sows farrow, and the feeding amount is increased or decreased in time after the sows farrow, namely in the lactation period. The sows fed according to the feeding management method of the sows are good in health, high in pregnancy rate and large in born number, piglets are strong and uniform, and economic benefits can be improved.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to a feeding management method involving four stages of sows: reserve, empty pregnant and mating, pregnancy, childbirth and lactation. Background technique [0002] The breeding methods of sows during breeding, breeding, pregnancy and delivery directly affect the quality and quantity of their litters. Therefore, the precautions for sow feeding and management methods are more cumbersome, involving the pig house environment, feed quality and quantity, and various stages. Grasp the time and observe etc. [0003] The current feeding method of sows is too rough and unreasonable, and does not grasp the key points of the four stages of reserve, empty pregnancy and mating, pregnancy, parturition and lactation, resulting in excessive or low nutritional levels and timing of mating of sows during the feeding process. Inaccurate grasp will lead to problems such as low conception rate,...

Problems solved by technology

[0003] The current feeding method of sows is too rough and unreasonable, and does not grasp the key points of the four stages of reserve, empty pregnancy and mating, pregnancy, parturition and lactation, resulting in excessive or low nutritional levels and timing of mating of sows during the feeding process. Uncertainty will lead to problems such as low conception rate, sow miscarriage, and bad farrowing, which will virtually increase the cost of feeding and reduce economic benefits
