Prevention and treatment of feed poisoning in dairy cows with improper feed treatment

In raising dairy cows, farmers often use all kinds of grass, vegetables, agricultural by-products and industrial by-products as feed, sometimes lead to cow poisoning due to improper feed handling, reduce cow yield and milk quality, and even die, affecting the development of cattle industry. In this paper, the prevention and treatment of cow poisoning caused by feed are introduced as follows:

Cow

Mildew corn causes disease: when mildew corn is fed to cows, the ruminating of the affected cows weakens or stops, corneal turbidity, mucosal yellow staining, diarrhea, weight loss, some insanity, excitement turn around, resulting in fainting and death.

Prevention: the water content of stored corn should be less than 12.5%. Mildew light corn can be soaked in 10% raw lime solution and then used as feed. Treatment: immediately stop feeding, add water to take 400 kg 600 grams of magnesium sulfate, 500 ml 1000 ml of glucose saline, 50 ml 40% urotropine.

Bad sweet potatoes cause disease: cows feed on bad sweet potatoes containing mycotoxins, and their spirits are lethargic, ruminating weakens or stops; constipation; shortness of breath, difficulty, severe coma, spasm, until death.

Prevention: do not feed black spot sweet potatoes to cows. Treatment: stop feeding immediately. Mix 500g of raw mung bean and honey, take it orally once, or pour 2000 ml 0.1-0.2% potassium permanganate solution. When constipation, take 400 grams of magnesium sulfate, while intravenous injection of 25% glucose 50 ml 1000 ml, 10% sodium coffee 10 ml, 5% sodium bicarbonate 250 ml 500 ml and so on.

Rotten cabbage disease: Chinese cabbage and all kinds of weeds, wild vegetables contain nitrate, after stuffy cooking or fever, decay will be oxidized to nitrite, cows will be poisoned after eating.

Prevention: vegetable feed should be fed raw, not rotten grass and vegetables. Vegetables and grass that need to be cooked should be cooked and fed right away. Don't stay overnight to prevent spoilage. Treatment: mild poisoning, 5% 7 egg white or milk 500g, severe dairy cows, intravenous injection of 1% 2% Meilan solution 150ml, 5% glucose 1000 ml, 10% sodium coffee 20ml. It can also be filled with 8-10 bottles of blue-black ink mixed with 1.5 times water.

Lees poisoning: lees contain acetic acid and alcohols, large amounts of feeding is also easy to cause cow poisoning. Symptoms are mental excitement, behavior instability, mucosal flushing, skin rash around the abdominal breast, constipation, dysentery alternately, accompanied by abdominal pain, paralysis, collapse and other symptoms.

Prevention: control the amount of distiller's grains, dry grains not more than 10%, fresh trough no more than 30%, prohibit mildew distiller's grains, mildly moldy, can be mixed with 1% lime water before feeding cattle. Treatment: take 1% baking soda solution or soy milk water 1500 ml, intravenous injection 5% glucose 1500 ml, rinse the affected area with 1% potassium permanganate solution.

Sprouting potatoes cause disease: cows eat sprouted potatoes or potato stems and leaves containing solanum solanum, the light ones regurgitate weakly, salivate, diarrhea, rash appears in the lower waist, and the heavy ones stop regurgitation, from agitation to depression, limb paralysis, spasms and convulsions to death.

Prevention: when feeding, remove sprouting, turning green and decaying parts, boil water loss, and match with other feed, pregnant cows do not feed potatoes. Treatment: gastric lavage with 0.1% potassium permanganate solution, oral tannic acid 1000 ml, severe cow intravenous injection of 5% glucose 1500 ml, 10% sodium coffee 10 ml.
