If you have a sweet potato with black spot disease, will the cow really be poisoned if you eat it? W

Sweet potatoes with black spot disease can really be poisoned if eaten, because this sweet potato contains a toxin that can attack the body of the cow.

If the sweet potato is stored for too long or the storage place is too wet, the skin will be brown, black spots or shriveled and concave, and the heart will become hard and bitter, which means that the sweet potato has been attacked by black spot disease.

Melanoma is caused by ascomycetes, which excrete toxins that are toxic to the human liver, even if boiled, steamed or roasted.

Cattle will not be poisoned if they eat it, because black spot is a fungus, and there are biological enzymes in the body of cattle that decompose this fungus after eating, which can reduce fungal activity and will not be poisoned.

Sweet potatoes are also called sweet potatoes, sweet potatoes or sweet potatoes, and some places are also called yam improper storage, often polluted with sweet potato black spot fungus, sweet potato alcohol, sweet potato and hydroxy sweet potato and other toxins, cattle swallow these moldy sweet potatoes, poisoning can occur.

Western medicine**: quickly discharge poisons, detoxify, relieve dyspnea and symptomatic **, take potassium permanganate 500 1000ml as soon as possible, take it once, after 2 hours, give 400g of magnesium sulfate, 150g of artificial salt, add 3000 5000ml of water, mix, once administered, slow diarrhea and clear the intestines.

Answer: After the cow eats the rotten sweet potato by mistake, it will immediately cause a poisoning accident, and the emergency is manifested as a high degree of difficulty in breathing, loss of appetite, and suffocation to death in a short time; The lighter ones will also die within four or five days. According to practice, the use of potassium permanganate to ** cattle accidentally eat rotten sweet potato poisoning disease, can receive very satisfactory results. The specific treatment methods are:

Take 1 gram of potassium permanganate and 10 ml of glucose injection, mix and dissolve, and slowly inject intravenously into the poisoned cattle. Inject once a day, usually twice in a row, and the sick cow will be safe**.

Sweet potatoes are also called sweet potatoes and white potatoes. Rotten sweet potato is caused by the parasitism of the fungus sacromycetes, when the epidermis of sweet potatoes is damaged, it can be infected, this fungus produces a toxin called sweet potato ketone, sweet potato ketone is resistant to high temperatures, and generally boiled, steamed, and roasted will not be destroyed, so cattle will be poisoned when they eat rotten sweet potatoes.

Most of the cattle in sweet potatoes do not have obvious precursor symptoms, sudden dyspnea, do not eat or drink, suffocation and death within a few hours to 1-2 days, the symptoms of poisoning appear relatively slowly, at the beginning of the cattle appetite is reduced, breathing is faster, restless, conjunctival hyperemia. Immediately after the rumination stops, the rumen peristalsis is very weak, constipation often occurs, the stool is black with mucus and blood, and sometimes diarrhea. In the later stage, the whole body has subcutaneous emphysema, cyanosis of the conjunctiva, bovine tearing, dry nasal mirror, foamy saliva from the mouth, and finally suffocation and death.

Sweet potatoes should not be fed to cattle with sweet potatoes with black spot disease, which will be poisoned if fed raw or cooked. Rotten sweet potatoes should be buried deep in a concentrated manner to avoid being eaten by domestic animals. Cattle should be rescued immediately after rotten sweet potato poisoning**.

Cattle eat differently, the degree of poisoning is different, and the symptoms are also inconsistent. Sudden onset of symptoms in pleiotropic diseased cattle; Panting is the most abrupt. out of the characteristics, so it is called cattle asthma".

The head and neck of the sweet potato sick cattle are straightened, the nose is fanned, the chest and abdomen breathe, and the breath sounds of individual sick cattle can be heard several meters away, and the breathing increases to 60 80 times; increased heartbeat, later low; Body temperature is mostly normal, and a few rise above 40; depressed, red-eyed, standing, rarely lying down; The ears and nose are cold, the ears are often drooping on one side, the appetite is little or nothing, rumination stops, and some sick cattle have subcutaneous swelling in the upper part of the neck, shoulder blades, elbows, etc., and there is a twist to the touch. trembling all over the body in the later stages of the disease; Mouth breathing and panting, unsteady standing, foaming at the mouth, muscle tremors, death from a few hours to 1 day in the most acute case, 2-3 days in the chronic case, or a delay of about a week or so in the case of poor performance.

Sweet potatoes should be rescued in time, and the symptomatic treatment is mainly detoxification, cardiotonics, antispasmodic, and diuretic. Chinese herbal medicine** often obtains good results.

Intravenous injection of high-dose glucose saline 1500 3000 ml, vitamin C injection 20 ml or 1 3 grams, can quickly strengthen the heart and detoxify, vitamin C helps intracellular respiration, has proenzymes, can prevent internal bleeding, promote the increase of red blood cells, hemoglobin, and reticular red blood cells. Atropine can be injected intramuscularly into spasms and repeated every 2 to 4 hours as appropriate. For those with elevated body temperature, high-dose kanamycin (15mg kg body weight) or cynical, streptomycin or berberine tablets and radix tablets can be taken intramuscularly to prevent and treat concurrent infections and reduce inflammation.

Sweet potato is also called sweet potato, sweet potato or sweet potato, improper storage, often infected with sweet potato black spot fungus, sweet potato mildew and deterioration, produce toxic substances, when cattle eat these moldy sweet potato, sweet potato skin and sweet potato processing by-products - powder residue, slurry, etc., poisoning can occur. The disease has a rapid onset, severe disease, and a high mortality rate.

Cattle more than 12 hours or 1 day after the sudden onset of the disease, after the first appearance of dyspnea, loss of appetite, rumination stopped, mental malaise, cold ears and nose, dark red tongue, limbs muscle tremor, especially the elbow muscles trembling violently, urine, dry dung, do not drink water, body temperature is generally normal. This is followed by a high degree of dyspnea, superficial rapid breathing, conflict-like breathing, and occasional squeezing sounds. In severe cases, breathing can reach 80 100 times per minute, the pulse is fast and weak, the conjunctiva is cyanotic, the sick cattle open their mouths to wheez, foam at the mouth, and often fall to the ground and suffocate and die.

Auscultation of the lungs is initially crackles and dyspnea, and later interstitial emphysema may be heard as ruptured rales, and soon subcutaneous edema appears, from the neck, back, and chest to the buttocks, crepitations on palpation, and hyperresonance or tympanum on percussion.

Precautionary measures] do not feed sweet potatoes with black spot disease and their by-products, strengthen management, and put a mouth hone on the ploughing cattle in the sweet potato season to prevent poisoning caused by accidental ingestion.

Rescue measures] 1) Strengthen nursing, let the cattle keep quiet, in the early stage of the disease, the digestive tract detoxification, detoxification and prevent toxin absorption are the mainstay, you can first use disinfectant water to lavage the stomach, and then give salt laxatives such as magnesium sulfate or sodium sulfate 300 500 grams, add an appropriate amount of water to administer; Or 200 300 ml of potassium permenate solution at a time, 1000 2000 ml of phlebotomy, and then 1000 3000 ml of 5% sugar saline, 500 ml of 5% sodium bicarbonate solution, mixed and injected intravenously once, sodium thiosulfate solution and ascorbic acid can also be injected intravenously.

2) To relieve dyspnea, 150 250 ml of 3% hydrogen peroxide solution can be mixed with 3 times more normal saline or 1000 ml of 5% glucose normal saline, and slowly intravenous injection. In the presence of pulmonary edema, 500 ml of 5% glucose and 100 150 ml of 10% calcium chloride can be injected intravenously once.

3) Symptomatic**: use cardiotonic drugs when the heart is weak, reduce inflammation when secondary pneumonia occurs, and strengthen the stomach when indigestion.

The appearance of black spots on the epidermis of sweet potatoes is usually formed because the sweet potatoes are attacked by black spot disease during the growth process, and the black spot sweet potatoes contain toxic substances such as sweet potato ketones and sweet potato ketone alcohols, which can make the sweet potatoes hard and bitter, causing damage to the human liver. For this toxin, no matter how steamed, boiled, roasted, fried and other cooking methods can not destroy its biological activity. Eating such sweet potatoes can easily lead to poisoning in the human body.

In addition, sweet potatoes with moldy and mildew on the skin are not recommended to eat. But not the black spots that appear on the surface of sweet potatoes are caused by diseases, in addition to soft rot and black spot disease will cause black spots on the skin of sweet potatoes, in addition to sweet potatoes in the harvest, it is very likely to collide with each other and cause the outflow of juice inside sweet potatoes, sweet potato juice contains a large number of antioxidant substances polyphenols, when they are combined with oxygen in the air, they will produce black spots, such black spots will not have adverse effects on human health.

Spotted sweet potatoes contain a variety of toxins, which can cause poisoning after eating, and the toxins have a great impact on the human liver. These toxins cannot be destroyed by boiling, steaming or roasting.

This is purely a quote. 1. Clinical manifestations and pathological changes.

1. Clinical manifestations: after severe poisoning, the cow's appetite is lost, rumination stops, the whole body is pure and trembling, dyspnea, and the number of breaths increases by 80-90 minutes. Sick cows with their mouths and tongues sticking out and a large amount of foamy saliva suffocate within 1-3 days.

The clinical symptoms of mild poisoning are mild, with only mild dyspnea and diarrhea, which can generally be cured after symptomatic treatment.

2. Pathological changes: the blood is dark brown, there are bleeding spots in the epicardium and pleura, and there is interstitial emphysema in the lungs with mild edema.

2. Diagnosis. According to the medical history and clinical symptoms of hailstorm, such as the onset of the disease after ingesting sweet potatoes, the body temperature of the cattle did not change at the time of the onset, but there were prominent panting symptoms. It is important to distinguish it from bovine infectious pleuropneumonia and bovine pasteurellosis.

Three**. Add 500 ml of 5% glucose saline with 125 ml of 3% hydrogen peroxide solution, and slow pants old and slow intravenous. Add 10 g of vitamin C with 500 ml of 5% sugar saline (5 g for the second and consolidated amount) and inject intravenously.

50% glucose injection 200 ml intravenously. 25 g of calcium gluconate was added to 500 ml of sugar saline and injected intravenously. Symptoms were reduced about 10 hours after using the above methods**.

Repeat the dose once on the 2nd day, and consolidate **1 time on the 3rd day.
