Affecting the growth of piglets
Improper weaning methods. Piglets originally had a mother-centered, cohabiting, stable and comfortable living conditions suddenly changed, suddenly weaning difficult to adapt to affect weight gain.
Feeding is not timely. The piglets did not feed in time during the lactation period, and they did not eat well after weaning. There was no milk supplement, causing slow growth and development.
Feed and feeding methods are unreasonable. After weaning, the piglet not only can not eat breast milk, and the feed quality is poor. Feeding material is less than water, and the number of daily feedings is also reduced from 6-8 times before weaning to 3 times a day. The drastic changes in these conditions make the piglets The normal development is hampered.
Rearing management is extensive. Before the weaning, the piglets are mother-centered and co-habitants. After weaning, piglets cannot adapt to this lonely life. Especially in cold weather, eating well does not sleep well, and it is prone to multiple diseases and even death. Some pigs eat, sleep, and defecate all at the same place, and they are not cleaned or gasketed, causing environmental pollution and poor sanitation. It is easy to cause a series of diseases such as colds and diarrhea in pigs, which seriously affects the health of pigs. Growth is extremely unfavorable.
Weaning, epidemic prevention and castration were carried out at the same time. Weaning and castration at the same time weaned. In this way, the three unfavorable factors of weaning, epidemic prevention, and castration were all added to the piglets, making it impossible for the piglets to recover in a very long period of time, which seriously affected the normal growth and development of the pigs. The pigs grew slowly and formed stiff pigs. Due loss.
Promote piglet growth strategies
Prepared before weaning. Piglets should be gradually reduced in number of nurses 5 to 6 days before weaning, until complete weaning.
Feeding in time during breastfeeding. Feeding should normally begin at 7 days of age in piglets so that when the sow's lactation levels decline, it can be officially supplemented to make up for the lack of sow milk production.
Adjust feed and feeding methods. The fine care for piglets was strengthened so that the quality and quantity of feed gradually transitioned, and the fine, green, and rough feeds gradually transitioned. The number of feedings gradually transitioned from 6 to 8 times to 3 to 4 times a day.
Strengthen piglet management. After weaning piglets, should not change the circle, do not mix group, do not change the material, piglets keep the original circle feeding 1 to 2 weeks and then transferred to the rearing house feeding. To clean and ventilate the pens, do a good job of sanitation and disinfection and cold and warm work.
Strict prevention and castration time. Small boars that are not normally kept can be castrated at 20 days and gilts can be cast at 30-40 days. For the prevention of swine fever, the swine fever vaccine can be injected at 25 to 35 days, and the swine fever vaccine can be immunized once at 60 to 70 days. For the prevention of highly pathogenic PRRS, the piglets should be firstly vaccinated after weaning.
