How to prevent and treat pig lice
Porcine lice disease, also known as porcine blood lice disease, is an in vitro parasitic disease caused by porcine liver lice parasitic on the surface of pigs. Although it can not cause painful death, it still has a considerable impact on the growth and development of live pigs, especially on piglets.
The developmental cycle of swine lice is short and spreads rapidly. after the fusion of male and female lice, the female lice ovulate and ovulate 4 times a day after being fed with blood. The larvae are hatched with secreted mucus on the fur for 1215 days and become adult lice for 104 days, and the development cycle is 2332 days.
Due to poor hygiene, narrow site, dense and crowded, poor management is the most likely to be infected with this disease. Through lactation, the lice on sows can infect all piglets, and the disease of fattening pigs in the same circle can quickly spread to the whole herd. Clinically, diseased pigs often scratch the body surface and bleed, restlessness, loss of appetite, malnutrition, emaciation and slow growth, especially the stagnation of liver growth and development of piglets, affecting production efficiency. Therefore, the prevention and control of swine lice disease is also important.
Prevention and treatment of diseased pigs
1. Spray pig body or medicine bath with 0.1% trichlorfon aqueous solution, Lin Dan liquid 300PPM, etc.
2. The body surface of pigs should be checked frequently, especially for pigs purchased from other places. As soon as they are found, they should be caught or killed by drugs.
3. To do a good job in the environmental hygiene of pig houses, it is necessary to disinfect them regularly, and the feeding density should not be too high.

Chicken diet mixing method
When using the diet, it is required that the nutrients contained in each part of the feed for chickens are balanced and the same, otherwise the chickens will be malnourished, lack of disease or poisoning, even if your diet formula is very scientific and the feeding conditions are very good, still can not get satisfactory feeding effect. Therefore, the feed must be stirred evenly to meet the nutritional needs of chickens. There are two methods of feed mixing: mechanical mixing and manual mixing. As long as they are used properly, satisfactory results can be obtained. Mechanical mixing: using a mixer. Commonly used stirring
