The mercury preparations, arsenic, organic phosphorus, and organic chlorine contained in pesticides, once eaten by livestock and poultry, will rapidly cause poisoning and death of livestock and poultry. Therefore, it is strictly forbidden to harvest green feed and grazing in areas that have been sprayed with the above-mentioned agents within a week and have not been washed by rain.
2. The saponin-poisoning saponins are mostly found in loquat and other leguminous plants and have the highest flowering content. The typical symptom is that cattle and sheep are susceptible to bloat after eating. Therefore, these green feeds should be mixed with other dry feedstuffs, and the amount of feed should be controlled to avoid poisoning.
3. Oxalate poisoning Sugar beet, spinach, cauliflower and green fur contain more oxalate, eating too much can cause domestic animal poisoning, leading to urinary tract obstruction, reduced blood calcium. Therefore, feeding this type of green feed should not be used in excess or alone, and can be mixed with other feeds or fed with boiled water.
4. Hemorrhagic acid poisoning When grasses such as hibiscus, lentils and other plants are rotted, hemoglobin will be decomposed due to heat. When internal and external wounds occur in livestock, severe bleeding or bleeding may occur. Therefore, it is strictly forbidden to use feeds such as heating uncooked or deteriorated grasshoppers.
5. Hemagglutinin Poisoning In legumes and stems and leaves of ramie, contains a certain amount of hemagglutinin, especially in fresh stems and leaves may be up to 1%, after feeding the livestock with this green feed, will lead to blood circulation disorders in livestock Causes severe pain and hemorrhagic gastroenteritis. Therefore, the green material should be cooked or fermented after feeding, and beware of eating during grazing.
6. Porphyrins Poisonous gray vegetables, wild leeks, stinky leaves, etc. Although it is a good feed for pigs, sheep, rabbits, but because it contains porphyrins, if not treated or fed excessive, can cause livestock puffiness, red Itching, subcutaneous hemorrhage, even serous blisters or blood vesicles, secondary local infection or necrosis. Therefore, the above-mentioned green material should be soaked or sun dried and fed with other feeds.
7. Mildew poisoning Various kinds of toxins with different toxicity will be contained in various green feeds that have been mildewed and piled up. Eating mildewed feed will cause vomiting, diarrhea, wheezing, convulsions, and even fainting. Therefore, it is strictly prohibited to stack green materials and prevent poisoning.
8. Colchicine poisoning Colchicine is contained in fresh feed such as daylily, parsley, and white sauerkraut, which can cause redness, dryness, and vomiting and diarrhea in the throat of pigs, sheep, rabbits, and fish and poultry. Severe bloody stools, hematuria, or urine closure. Therefore, the above-mentioned green feed should be soaked in water, and it is safer to feed after squeezing the water.
9. The ricinine poisoning stems and leaves of ramie contain 0.2% ricinine, taking 0.16 grams of ricinine can make the pigs die. Therefore, ramie stems and leaves can not be fed fresh or pasture, and should be fed after heating to destroy the toxins.
10. Cyanoguanidine Poisoning In plants, cyanogenic glycosides often coexist with enzymes and release toxic hydrogen cyanide under certain conditions. Liver intake of corn leaves, sorghum leaves, red clover, pumpkin vines, etc. will occur poisoning. In particular, corn seedlings and sorghum seedlings that have been regenerated after harvest are most toxic. Therefore, the feeds mentioned above should not be fed fresh and should be sun dried and used for feeding with other feeds. Avoid use of post-harvest sorghum seedlings and corn seedlings to feed livestock to avoid poisoning.
The fire-free cupping tool that is pumped into a vacuum and negative pressure state overcomes the shortcomings of traditional cupping. The main feature is that the tank is transparent, the negative pressure in the tank can be adjusted at will according to the patient's physical condition and condition, easy to observe the skin changes in the tank, easy to grasp the cupping time, safer to use, easy to operate, so it is not only suitable for hospitals, but also more extensive Is suitable for families.
