What is the reason why piglets tend to lose weight after weaning?

Piglets will take weaning measures when they are raised to a certain age, and if they are not weaned in time, it will lead to serious growth retardation of piglets, but piglets often lose weight day by day after weaning, and it is even possible to become stiff pigs. so what's the reason for this? Come and have a look with the editor.

1. Environmental factors

After weaning piglets and sows were raised separately, when its living environment changed greatly, from sow feeding to independent life, these changes often caused a series of stress reactions. There is a phenomenon of restlessness and loss of appetite, so it is very important to make a good environmental transition of piglets before weaning, in order to prevent the restlessness of piglets after weaning. Sows can be removed and piglets raised in the original pen, so that the living environment of piglets will not be changed, or piglets with similar physique can be formed into new groups, and this phenomenon will not occur.

2. Feeding factors

Weaning of piglets is a gradual process from liquid milk to solid feed. In this process, the gastrointestinal system of piglets needs to be fully improved in order to be suitable for solid feed. However, in the actual feeding process, due to improper operation or low feed digestibility, resulting in a high proportion of dry matter in feed, piglets can not adapt to the intestines and stomach, it will lead to anorexia. Therefore, liquid feed should be adopted in the early stage of weaning, which can not only improve dry matter nutrition for piglets, but also make piglets adapt to their intestines and stomach.

3. Disease factors

Piglets are physically weak, so their resistance to the outside world is weak. Some piglets are prone to diarrhea when they are weaned, which are all caused by diseases. In some pig farms, the incidence of diarrhea after weaning is very high, up to 80%, and the mortality rate is up to 20%. Diarrhea is often the main reason for the slow growth and development of piglets, which is very likely to cause stiff pigs.

4. Other reasons

The small intestinal villi of piglets will atrophy to a certain extent after weaning, and the degree of atrophy and feed intake during the transition period have a large root system, which will often cause indigestion, intestinal damage and Escherichia coli and salmonella infection. In addition, the immune function of piglets will decline because of the decrease of source antibodies after weaning, which will cause bacterial infection, serositis, respiratory diseases and stiff pigs.
