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 of sheep drinking water in winter and spring is 20-30 ℃.
The form of drinking water in order to promote sheep to drink more water, drink enough water, can give sheep to drink fine feed soup. The method is: first, rinse the concentrate feed with boiling water, stir it evenly, make it into a paste, and then mix a certain amount of water evenly for the sheep to drink.
The amount of drinking water sheep feeds on 1 kilogram of dry matter and needs 3 to 5 kilograms of water. Therefore, in winter and spring, depending on the situation of sheep eating forage, sheep should be given water of 3 to 5 times the quality of dry matter.
Drinking time to drink sheep on an empty stomach, if the water temperature is on the low side, it will make the sheep's body temperature drop suddenly, it is easy to make the sheep catch a cold and have a fever, and pregnant ewes are easy to miscarry if they drink cold water on an empty stomach. In production, the sheep should be given water after 1 hour of grass feeding, so that the water and forage can be fully mixed in the rumen of sheep, which is helpful for digestion.
It is suitable for sheep to drink water twice in the morning and in the evening. If the conditions are not met, drink at least once, but be careful to drink enough.

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. Second, due to malnutrition, the endocrine disorder of sows is caused, and the estrous cycle of sows is delayed.

Environmental Control of Pigs
1 when 7~8kg weaned piglets enter the nursery, the suitable ambient temperature should be maintained at 24.5 ℃, and the suitable ambient temperature at 20~25kg should be 23.0℃ ~ 24.5℃ (generally, the temperature should be increased by about 2 ℃ ~ 3 ℃ after weaning). (2) to create good environmental conditions for pigs to be susceptible to pathogen infection, so the house should be kept dry. The environment is clean and hygienic and the air is fresh. Use wooden boards or electric heating plates as mattresses to prevent piglets from getting cold in the abdomen and wearing out their feet and knees.
