Pay attention to the four key "three days" of pig farming

There are many critical "three days" in the process of raising pigs, during which strengthening the feeding management will greatly improve the production efficiency. The main results are as follows: 1. three days after mating is the key period for egg fertilization and division of fertilized eggs. if the metabolism of sows is too high, some of the fertilized eggs will die and the litter size will be reduced. Therefore, sows should not be fed too much within three days after mating, and the daily feed quantity should be 1.5 Mel 1.8 kg, not more than 2 kg at most. 2. Three days after delivery, the feeding and management of newborn piglets is very important, because many casualties occur in this stage, such as frostbite, frostbite, crush, disease and so on. In order to reduce the death and injury rate of piglets in these three days, the following work should be done: proper delivery of ① and keeping warm and moistureproof. ② allows newborn piglets to eat colostrum in time to enhance disease resistance. ③ fixed nipple. This is an important measure to reduce the death of newborn piglets and improve the evenness of piglets. ④ supplements iron and selenium in time to prevent selenium deficiency and anemia. ⑤ can restore the condition of sows and prevent postpartum infection. 3. Three days after weaning, this is the most serious stress period for weaned piglets: the imported food changes from liquid milk to solid feed, leaving the care of sows, and because the temperature of sows is greatly reduced, the supply of maternal antibodies is stopped. Each of the above stress will have a very adverse effect on piglets and become the inducement of the disease. Reducing stress is the key to help piglets to be weaned smoothly, drug prevention is an effective auxiliary measure to prevent secondary infection of piglets, and comfortable environmental conditions and high quality feed are the guarantee of successful weaning. 4. Three days after the conversion, the new feeding environment will cause physiological and psychological maladaptation of piglets, and the disease resistance will also be reduced. Piglets from different litters will re-establish their status in this new group through "competition". At the same time, the three-point positioning of eating, pulling and sleeping of piglets will also be completed in these three days, all of which require a lot of energy. In order to ensure the smooth transformation of piglets, the following work should be done: ① should make the ambient temperature close to that of the new environment as far as possible. ② was fed with the original feed for a period of time, and then gradually changed to the fattening feed after all the conditions of the pigs were stabilized. ③ strengthens drug prevention to prevent bacteria from invading piglets. The phenomenon of fighting often occurs in ④ piglets after mixed herds, so we must always pay attention to guard against some breeds with high stress response. -take it first and study slowly.-Thank you for your hard work.-Yes, thank you! -study.-Thank you!
