To avoid stress in weaning piglets, what should we pay attention to in feeding management?

Piglets are weaned under environmental stress, psychological stress, and nutritional stress. These stresses will lead to a decline in piglet health and weakened resistance, resulting in weaning and diarrhea, slow growth or low fertility.
  
I. Environmental Stress
  
From a familiar and warm environment to an unfamiliar environment, if coupled with weaning and weaning of piglets and biting each other, there will be stress. At this time, the function of piglet temperature regulation is not perfect, which will lead to decreased resistance. .
  
Second, psychological stress
  
When a piglet is weaned and leaves its unaccompanied and familiar environment, it will definitely have some negative effects, such as anxiety, looking for its mother, not feeding.
  
Third, nutritional stress
  
Because breast milk is comprehensive and easy to digest, the temperature is suitable, when the breast milk is insufficient before weaning, piglets like to eat feed; but when weaning leaves the mother, due to environmental and psychological stress, piglets do not like to eat feed, coupled with solid feed nutrition is not Comprehensive, poor palatability, and difficult to digest. One or two days before weaning, the piglets did not eat. When the hunger became intolerable, they began to eat a lot. As a result, they overeat and the digestive function of the digestive system is not sound. , Causing nutritional diarrhea.

1.Second heating
  
Before the piglets are weaned into the nursery, the nursery must be carefully disinfected repeatedly and the insulation equipment is intact. Raise the temperature to 25-30 ° C, or even 30-32 ° C in advance, to reduce the stress of piglet weaning. Gradually cool down later.
  
The warmth of the nursery is mainly the warming of the ground. The temperature rises in the place where the piglets lie, and the ambient temperature is 20-25 ° C. A large warm box can also be used, which can save energy costs.
  
2. Wet and dry feeding
  
Piglets need to have an adaptation process from eating warm fluid breast milk to eating solid feed. In order to reduce the stress of this process, liquid or porridge can be used. Soak the feed in warm water, and add some dairy products, antibacterial peptides, enzyme preparations and glucose to improve the palatability of the feed. As long as the piglets can eat the food, the feed intake does not decrease, and the survival rate will definitely increase.
  
The feed supply of freshly weaned piglets should be gradually increased according to the average feed intake of the piglets in the delivery room. It is not possible to increase the feed in one step to avoid excessive nutritional diarrhea caused by piglets.
  
3. Training piglets for "three-point positioning"
  
Piglets rest, feed, drink, and excrete in one place. Keep the rest place in clean gel, do not excrete in the place of feed, and excrete in a fixed range. If this work is done well, the labor intensity of the workers will be greatly reduced, and more energy can be focused on observing the health of the piglets.
  
4. Grouping according to weaning weight
  
Piglets with a small body weight are more sensitive to various stresses and are prone to disease outbreaks. Piglets with a small body weight will be raised and raised separately to increase the local temperature and increase the nutritional concentration of the feed. Add dairy products, antibacterial skin, enzyme preparations, glucose, Feed with liquid feed. Can increase the survival rate of piglets.
