Adhere to the principle of limited feeding. Adult boars should generally be controlled at a weight of 150-200 kilograms, because the nutritional level is too low or too high, can cause the boar's weight is too small or too large, easy to cause boar health disorders and reproductive performance Decline.
The daily feeding amount of boars varies slightly due to different growth and development stages and seasonal factors. Under normal circumstances, adult male boars should supply 2.5-3 kg of compound feed and 2.5 kg of green feed every day; young boars Each day should be fed with 2-2.5 kg of compound feed and 2 kg of green feed.
Feeding should be based on the principle of regular ration. Feed it once a day in the morning, in the middle of the day, and in the evening. The ration should be regular and the pigs should be full without food. The feed ratio is 1:1. In the cold and hot summer season, we must do a good job of preventing cold and keeping warm, and at the same time we should properly increase the nutritional level of feed, supplement vitamins and trace elements, promote appetite, and meet nutritional needs.
The breeding season should increase animal protein feed. In the breeding season, when there are more estrus sows, 2% more animal protein feed such as fishmeal should be added to the feed of the boar, for example, 2-3 shelled raw eggs can be fed every day, which can significantly increase the semen of the boar. quality.
Provide plenty of clean drinking water. A duck-billed drinking fountain can be used on conditional farms, and free drinking water is appropriate. If sinks are used for drinking water, pay attention to the hygiene of the sinks and keep them dry and hygienic.
Appropriate increase in exercise. When the feces is cleaned every day, you can drive the boar movement in the column. You can also use the playground outside the bar to allow them to move freely. In the winter, they should be warm at noon, and in the summer, they should be cool in the morning and in the evening.
Check semen quality regularly. For boars with artificial insemination, the quality of semen should be checked every time sperm production is performed, and the death of boars and weak boar breeding of boars should be strictly prevented.
Reasonable use of boars. There are libido performance before and after 6 months of age, but this time, sex and body are not mature enough to be used. Generally should be 10-12 months of age, weight more than 100 kilograms began to use better. One-year-old male boars can be bred three times a week; 2-5-year-old male boars can be replenished one or two times a day, preferably in the morning and evening before each feeding, with a rest of 1-2 days per week; Boars older than 6 years old can be bred once every other day. All boars should not be used excessively to avoid premature termination of the boar's useful life.
It can be used for surgical operations, patient treatment; epidemic prevention and inspection in public places; disinfection in virus-contaminated areas; and can also be widely used in military, medical, chemical, environmental protection, transportation, epidemic prevention and other field
By setting a protective collar, the neck of the operator can be kept warm and protected. The provision of a hand guard is helpful for the surgical staff to temporarily place their hands in the hand guard while waiting during the operation, which plays a protective role and is more in line with the principles of aseptic operation and occupational protection.
By setting the shrinking cuffs, it is beneficial to make the cuffs fit the wrists, prevent the cuffs from loosening, and prevent the gloves from slipping off during the operation and the operator's hands are exposed to the gloves.
The design of the new humanized protective surgical gown has been improved in the key areas of the gown. The forearm and chest area are double-thickened, and there are handguards in front of the chest and abdomen. By arranging reinforcing sheets (double-layer structure) in key areas, it is beneficial to improve the water-permeability of surgical gowns and improve safety.
