Pig driving skills
1. Design a road for pigs: that is, when you enter the pigsty or get on the bus when selling pigs, there is a man-made road, and the walls of this road had better be fixed and solid walls. If not, you can use temporary walls, such as iron railings, long stripes of colored cloth (you can also sew long stripes of cloth with feed bags), or other opaque boards, so that pigs can see that it is right only to move forward. in this way, the general pig will follow the path designed for it; this method is more practical for sows. 2. Temporary wall

Pigs with reasonable feed are not anorexic
When the temperature rises above 35 ℃, the feed utilization rate is low and the weight gain is slow. Therefore, different feeding methods should be given according to different types of pigs and different physiological stages of pigs in high temperature season. Boar: feed twice a day, plus green fodder or thinner at noon. Mating and exercise are carried out in the morning and evening, do not immediately hit Wang or spray cold water after mating. Spray water on the pig body and ground once from 1 pm to 3 pm every day, and the light is reduced to 8-10 hours. if the number of mating is less, the amount of concentrate feed should be reduced to prevent overfertilization.

Ingenious identification of fish satiety
First, pay attention to the length of time for fish to eat on the table or in the food market. If after putting in a certain amount of feed (normal feeding amount), the time for the fish to finish the feed is less than 2 hours, it means that the feed is insufficient, and some fish are not eaten or full, so it should be added appropriately. If the amount of feed per ten days is constant, the daily amount of feed is the same within ten days, but the feed is eaten by the fish in less than 2 hours at the end of the decade, indicating that the fish has gained weight and the amount of feed should be increased. When fed with pellet feed, the feed has been finished and the fish are still swimming on the surface of the water.

Occurrence and prevention of eel disease
Ricefield eel lives in water with complex environmental factors all the year round and is often attacked by pathogens such as viruses, bacteria and parasites. In the process of raising ricefield eel, its physiological condition is disordered due to sharp change of water temperature, lack of dissolved oxygen, excessive acidity of water, poor feeding and management, such as insufficient food, malnutrition, or feeding rotten and deteriorated feed, and the deterioration of water quality. the body of the eel is weak, the resistance is poor, and serious cases often cause a large number of deaths. Even if it does not die, it will directly affect the growth and development of Monopterus Albus. Some are due to excessive stocking density, or artificial.

Two wonderful ways to domesticate fish on stage quickly
In recent years, with the continuous development of fish culture technology, the method of fish culture with full-price pellet feed has been gradually popularized and applied. However, because many fish farmers are unable to feed and domesticate, the domesticated fish do not know how to come to the stage, which not only affects the feeding and growth, but also increases the cost and affects the feeding efficiency. Below, we will sum up in the production practice of two simple and easy successful domestication methods to the majority of users for reference. First, the feed hanging bag domestication method uses the big eye window screen (with no leakage) to make a hanging which can hold 1.5 kilograms of feed.

Processing of freshwater "fish sausage"
1. Raw material pre-treatment: the fresh fish caught should be quickly sent to the processing plant to remove the fish with peculiar smell and corruption. Remove the viscera and head of the fresh fish and rinse the blood stain with clean water. If the fish cannot be processed in time, the fish should be frozen and stored at minus 18 degrees Celsius. It is better to thaw frozen fish with running water. The water temperature should be controlled at about 10 degrees Celsius. 2. Meat picking: the meat extraction rate is controlled at about 25%. If the meat extraction rate is too low, it will affect the finished product yield and cost; if the meat extraction rate is too high, tens of thousands of hemoglobin will be collected.
