Raising pigs with high efficiency pays attention to the four key "three days" in the process of raising pigs

There are many key three days for raising pigs, such as three days after mating, three days after delivery, three days after weaning, three days after transformation, and so on. In these three key days, strengthening feeding management can improve the production efficiency of raising pigs.

1. Three days after mating. Three days after mating is the critical period for fertilization and division of fertilized eggs in sows. If this era is too prosperous, it will lead to the death of some fertilized eggs and reduce the litter size. Therefore, do not feed the sows too much concentrate within three days after mating, the daily feed should be 1.5-1.8 kg, no more than 2 kg at most.

2. Three days after delivery. Three days after delivery is very important for the feeding and management of newborn piglets. Because many casualties in the process of raising pigs, such as freezing to death, crushing to death, illness and death, etc., all occur at this stage. Therefore, these tasks should be done three days after delivery: (1) proper delivery and warmth. (2) piglets eat colostrum in time to enhance disease resistance. (3) fixed nipples. (4) timely supplement of iron and selenium to prevent selenium deficiency and iron deficiency. (5) to restore the body condition of sows, prevent postpartum infection, and strengthen management to make sows go through the period of physical weakness smoothly.

3. Three days after weaning. These three days are the most serious stress period for piglets: food from liquid to solid, leaving the care of sows, sows being driven out of the house to lower their temperature, and stopping the supply of maternal antibodies. The key to smooth weaning of piglets is to reduce stress, the effective auxiliary measure to prevent secondary infection of piglets is drug prevention, and the guarantee of successful weaning of piglets is comfortable environmental conditions and high-quality delicious feed.

4. Three days after the conversion. The three-point positioning of eating, pulling and sleeping of piglets should be completed in these three days. in order to ensure the smooth transformation of piglets, the following work should be done: (1) make the temperature of the transition environment close to the new environment temperature as far as possible to reduce stress. (2) feed the pigs before conversion for a period of time, and then gradually change to the fattening feed after all the conditions of the pigs have stabilized. (3) strengthen drug prevention to prevent bacteria from invading piglets. (4) pay attention to observation and deal with the emergency of piglets in time. Piglets with mixed herds often fight, and piglets with strong stress response must always pay attention to the change of group.
