Feed and management of pigs
1. Reasonable grouping: reasonable grouping according to individual size, physical condition, etc., with moderate density, not too big or too small
2. Do a good job of training: (1) prevent the snatching of weak food, help to establish a social order, separate arrangement and uniform feeding. (2) fix the living place, make the food, sleep and defecation three positions, and keep the enclosure dry and clean. (3) provide adequate drinking water and match diets reasonably. (4) deworming regularly.
Special wild boar has a wide range of feed sources and is resistant to roughage. The feed cost is only 40% 50% of that of domestic pigs. The formulations for different pigs are as follows:
Boar ingredients: corn 30%, wheat bran 15%, rice bran 20%, fish meal 5%, salt 0.3%, sweet potato or pumpkin 30% (cabbage, kohlrabi, carrots).
Sow ingredients: corn 20%, rice bran 30%, crude bran 15%, sweet potato or pumpkin 30%, salt 0.4%.
Piglet ingredients: corn 30%, wheat bran 15%, rice bran 10%, secondary meal 20%, fish meal 5%, pumpkin 20%, salt 0.3%.
The above formula can be adjusted according to its feeding effect: (the missing part of the feed variety can be used as a substitute, such as pumpkin can be replaced by sweet potato and potato).

Comprehensive Control of White Crown Disease in Chicken
First, clinical symptoms: the feed intake of sick adult chickens decreased slightly, mouth flow with blood and mucus, slow weight gain, dilute feces, mostly between 60-100 days old, and the mortality rate was about 0.2%. The main manifestations of laying hens were decreased feed intake, pale crown, decreasing laying rate, thinner eggshell and more abnormal eggs. Second, treatment: continuous use of Baiguanling or Baiguanjing for 5-7 days can achieve significant results. The feed intake of adult chickens increased significantly, stopped dying from 3 to 5 days, and gained weight. Generally speaking, the laying hens began to improve obviously from 5 to 6 days, and the crown gradually changed.

Low sperm count requires at least 50 to 100 million sperm per ejaculation. Sperm motility decreased by 9. 5%. The weight of a rooster is 10. 5% lower. Genetic factors 11.
