Matters needing attention for raising pigs in fermentation bed in winter

The temperature is low in winter, especially in the north, which is a challenge for farmers, so the fermentation bed culture technology is becoming more and more popular, which can significantly increase the indoor temperature in winter. So what should we pay attention to when raising pigs in a fermentation bed in winter? Come and have a look with the editor.

1. Cushion requirements

If the cushion maintains the spatial structure, the air can easily enter the space, and the normal fermentation can be sustained. after the fresh cushion is used for a period of time, its physical behavior will change, and it is easy to hardening, sticking and decreasing air permeability. The dryness is the key to the normal operation of the fermentation bed. You can keep the cushion dry by strengthening the ventilation of the pig house, keeping the cold and warm of the pig house, replenishing the cushion, maintaining the thickness of the cushion, and reducing the feeding density.

2. Regular maintenance of bedding materials

According to the accumulation of feces and urine, the humidity of the cushion material should be flipped and pushed evenly, so as to avoid excessive humidity and the occurrence of blistering bed phenomenon. Fermentation bed technology can be used in winter, and the thickness of cushion material can be increased appropriately when breeding, but the minimum should not be less than 70cm. In order to improve the fermentation intensity, increase the amount of bacteria, spray brown sugar water and other methods, so that the fermentation bed deodorization environmental protection and heat preservation effect to the best. In order to replace the failure regularly, it should be replaced once in 2-3 years, which can be determined according to the pig feeding density and specific use.

3. Ventilation

Many farmers often have conflicts between ventilation and warmth in the process of breeding, and it is actually a mistake to close all kinds of vents when the temperature is low. Using the fermentation bed culture technology, the ventilation in winter can not be less, otherwise the aerobic microorganisms in the fermentation bed will die due to lack of oxygen due to the strong smell of ammonia, high humidity and poor ventilation, resulting in the failure of the fermentation bed. Therefore, the fermentation bed also needs to be ventilated in winter, all vents can be opened when the temperature is good during the day, and some vents can be left at low temperature or at night, which must not be completely closed.

4. Other fruits

Low temperature in winter, we should pay attention to drinking water temperature, pigs should not directly drink cold water, cold water can be heated for pigs to drink, or extract deep groundwater for pigs to drink. When the temperature is low in winter, most of the heat of the pig body is used to resist the severe cold, so it is inevitable that the body weight will not decrease, and the feed intake can be appropriately increased to make up for the weight deficit caused by fat and intramuscular metabolic heat production in pigs caused by low temperature. Feed can increase energy levels by about 10%.

The above is the fermentation bed winter pig breeding points for attention, hope to help you, want to know more related knowledge, please pay attention to us.
