Determine the weaning time of piglets from six aspects
1. The growth and development of piglets must be good: piglets that are well-growth should have a minimum body weight of 5 kg at 3 weeks of age, 6 kg at 4 weeks of age, and 7 kg at 5 weeks of age. Otherwise, it indicates that piglets have poor growth and weaning should be delayed. Particular attention should be paid to the fact that piglets must weigh more than 5 kg when weaning. Otherwise, the mortality of piglets after weaning is high and the survival rate is low. 2. The piglet feed should have a certain ability to feed: After weaning piglets, the required nutrients all come from the feed, if the feed intake is poor, it will easily lead to nutrient deficiency after weaning, leading to growth retardation and even death. Therefore, the piglets should have a certain feed intake before weaning. In general, the daily dry feed intake of weaners should be weaned above 150 grams. 3. Weaning age must be appropriate: Weaning age is earlier than 21 days of age, piglets have poor resistance, are susceptible to disease, and have a low survival rate after weaning. According to the reality of rural China, weaning at 35 days is more appropriate. If the feeding conditions are poor, weaning can be extended to 42 days of age. Feeding conditions can be improved to early weaning at 28 days of age. Regardless of feeding conditions, blindly pursuing early weaning is not worth the candle. 4. The piglets have good breeding conditions: After weaning, the piglets are generally uneasy. At the early weaning stage, they often have little or no food. Therefore, the resistance will decline. When piglets are weaned, they should avoid bad weather such as heavy winds and heavy rain. The temperature of the pig house should not be lower than 18°C ​​and should be warm and dry. If the ambient temperature is too low, thick grass bedding should be used to install infrared lamps and other warming measures. After weaning, the piglets should be kept in the original circle. The feed formulation must ensure that the nutritional needs of the piglets are met and the full price of the feed is guaranteed. 5. Piglets must be healthy: If the piglet is weaned during the illness, not only will the feed intake after weaning decrease, but it will also seriously impede growth and development, and the stress that the weaning will bring to the piglet will affect the therapeutic effect and even aggravate the condition. Therefore, at weaning, piglets must be healthy and disease-free. 6. During immunization and castration should not be weaned: immunization and castration, if coupled with weaning this stress will often increase the piglets discomfort after weaning, unfavorable piglet safe weaning, and will affect the immune effect, so weaning to be immune Injections and castration are separated for a period of time to allow the piglets to survive the weaning difficulties.
