Strengthen the drinking water management of pigs
To strengthen the drinking water management of pigs, to supply adequate drinking water according to the physiological characteristics of pigs, to meet the water needs of growth and development, especially for fattening pigs, water management should be strengthened. The specific methods are as follows:
1. Set up a drinking sink. In order to meet the drinking water needs of pigs and avoid all the disadvantages caused by insufficient drinking water, households should drink water to pigs at least 4-5 times a day. It is best to set up a special drinking tank in the pig house or activity field to allow pigs to drink water freely to meet the water needs of pig growth and development.
two。 Drink water according to the physiological characteristics of pigs. According to the data, pigs need 2-5 kg of water for every 1 kg of dry feed. The amount of water consumed by pigs is slightly lower in winter, 2-4 kg for every 1 kg of dry feed, 8 kg for 1 kg of dry feed in spring and autumn, and 10 kg for 1 kg of dry feed in summer. Lactation sows need more water. Therefore, no matter feeding compound feed or mixed feed or simple feed, pig farmers should meet the basic physiological needs of pig drinking water, and it is best to feed concentrate feed with some green and succulent green feed at the same time.

Effect of Light on Pigs
The light of piggery can be divided into natural light and artificial light according to different light sources. Natural illumination means that direct and scattered light from the sun enter the pig house through transparent structures such as doors and windows. Visible light accounts for 50% of the solar spectrum, and the remaining 50% is mostly infrared light and a small amount is ultraviolet light. The natural light of the pig house is generally expressed by the ratio of the total area of the pig house that can be transparent to the ground area of the house, which is called the lighting coefficient. Artificial lighting is illuminated by artificial light sources (incandescent or fluorescent lamps, etc.). Infrared light accounts for 60% of the spectrum of incandescent lamps.

Etiological diagnosis and analysis of pig bite rack
In the process of pig breeding, the phenomenon of pig bites (including tail biting) often occurs, especially the lean pigs which grow fast and can not keep up with feeding and management are more likely to occur, and the wound is inflamed and ulcerated, which affects the production of live pigs. caused a lot of economic losses. Here, briefly talk about the inducement of pig bites and solutions for reference. The main results were as follows: (1) the inducement of pig bites 1.1 the feeding density was high (piglets > 3 / m2), the feeding trough was narrow, and the conflict of contact was frequent. 1.2 single
