Prevention and control of swine lice disease
Porcine lice disease is an in vitro parasitic disease caused by pig liver lice parasitic in the coat of the body surface. Although it can not cause pig death, it has a considerable impact on the growth and development of pigs, especially on sub-pigs. The development cycle of pig lice is short and spreads rapidly. after mating between male and female lice, the female louse absorbs enough blood and ovulates, laying 3-4 eggs a day. The eggs adhere to the pig coat and hatch for 12-15 days. The young lice become adult after 10-14 days, and the development cycle is 23-32 days.

Prevention of false pregnancy in sows
What is a fake pregnancy? Sows do not get pregnant after breeding, but their bellies get bigger day by day, and their breasts gradually expand. In the end, they can even squeeze out some clear milk, but they do not give birth, and their bellies and breasts gradually retract. This phenomenon is called false pregnancy. Causes of false pregnancy: first, due to early embryonic death and absorption, and the corpus luteum of pregnancy does not disappear, resulting in progesterone secretion, as if pregnancy is still continuing.

Ensure that sheep drink enough warm water in winter and spring
Due to the low temperature in winter and spring, if you give sheep cold water, or even ice ballast water, sheep do not want to drink, it will cause insufficient drinking water for sheep. This not only slows down the process of sheep feed digestion, hinders metabolism in the body, and reduces body fat, but also causes various diseases. Therefore, it is necessary to create drinking conditions for sheep in production to ensure clean and adequate drinking water. Drinking water temperature if the temperature of the water consumed by the sheep is too low, the water should absorb the heat converted from the feed itself, which will reduce the utilization rate of the feed. Therefore, the best temperature for sheep to drink water in winter and spring is 20: 30.

Snake parasite
There are many kinds of parasites in snakes, such as whip tongue parasitic in snake lungs and trachea, heterotrematodes parasitic in snake gallbladder and so on. However, due to the short history of artificial breeding of commercial snakes and the limited production scale, there is not much communication on snake disease among snake farms, and the research on the status and control of internal parasites of snakes is not deep enough. Moreover, some drugs in the treatment of snake drug parasites, if the dosage is small, it will not work on the internal parasite; if the dosage is slightly larger, although it has not reached the lethal dose of the internal parasite, it is enough to cause the snake to cause.
