First, feeding a single best feed to the pigs nutritionally full-priced compound feed. Feeding fine feed should be matched with roughage, and appropriate amounts of minerals and trace elements should be added. Add 1% to 2% of mineral feed in pig diet, such as bone meal, calcium hydrogen phosphate, eggshell powder, etc., and add 0.25% to 0.5% of salt, etc., in order to prevent the pig from having a certain effect at the time of molars. Each day feeds bone powder or eggshell powder, calcium bicarbonate powder 30 to 50 grams, salt 6 to 19 grams, feed for 7 to 10 days, and the phenomenon of bruxism at night can be eliminated.
Second, digestive disorders for indigestion of the pig to stomach, can use a variety of methods. For example, for pigs weighing more than 10 kilograms, 10 tablets of rhubarb soda with a content of 0.3 g will be fed to the final spices and fed twice a day. Even feeding for 3 days can have a stomachic effect. If at the same time with Atractylodes 20 grams, Poria 30 grams, 30 grams of dried tangerine peel, chicken 10 grams, 30 grams of malt, 10 grams of licorice, fried juice sauce after feeding. Feeding 2 times a day, even feeding 5 days, can also play the role of digestion.
Third, parasites When there are parasites in the pig body, there will also be the phenomenon of bruxism at night, must be promptly removed. Deworming pigs, generally in the pig under the premise of other diseases, at noon to stop eating, to 8 to 9 pm when the pig fasting, according to pigs per kilogram of body weight, with albendazole or levamisole, anti-creep sensitivity or deworming net Each 15 to 20 mg, pulverized, mixed with a small amount of concentrated feed, fed once. Two days after feeding, 1 kg of quicklime was dissolved in 5 kg of water, and the supernatant was taken. The feed was continued and fed once a day. After feeding for 2 days, parasites in the pig could be repelled.
Fourth, vitamin deficiency is caused by lack of vitamins in the body (especially vitamin D) caused by the tusks of the pig, vitamin AD injection can be used in pigs per kilogram body weight of 0.1 ml intramuscularly, and fed complex vitamin B, 2 times a day, 20 tablets each time For 7 days.
Centrifuge tubes are precision-made, high-strength tubes of glass or plastic made to fit exactly in rotor cavities. They may vary in capacity from 50 mL down to much smaller capacities used in microcentrifuges used extensively in molecular biology laboratories. Microcentrifuges typically accommodate disposable plastic microcentrifuge tubes with capacities from 250 μL to 2.0 mL.
Glass centrifuge tubes can be used with most solvents, but tend to be more expensive. They can be cleaned like other laboratory glassware, and can be sterilized by autoclaving. Small scratches from careless handling can cause failure under the strong forces imposed during a run. Glass tubes are inserted into soft rubber sleeves to cushion them during runs. Plastic centrifuge tubes, especially tend to be less expensive and, with care, can be just as durable as glass. Water is preferred when plastic centrifuge tubes are used. They are more difficult to clean thoroughly, and are usually inexpensive enough to be considered disposable.
