Hematuria edema station instability spasm feeding cow cottonseed cake beware of cow poisoning

The commercial value of cotton seeds lies in oil and other products. Cottonseed oil can be used as salad oil and edible oil, and hydrogenated as ghee and margarine. The cake residue or seed after oil extraction can be used as feed for poultry and livestock. And the cottonseed cake pressed in the soil contains more gossypol toxin, such as a large amount, long-term use to feed cattle, poisoning will occur.

Cattle

Symptoms of bovine cottonseed cake poisoning:

Diseased cattle have depressed spirit, loss of appetite or even abstinence, reduction or cessation of rumination, relaxation of forestomach, enhanced intestinal sound, diarrhea and mixed blood in feces. Low body temperature, increased pulse, accelerated breathing. Micturition frequency, often with pain, hematuria or hemoglobinuria, urine sediment examination of renal tubular epithelial cells and various tube types. Edema often occurs in the mandibular space, neck, chest and abdomen and limbs, and some diseased cattle mouth and nosebleed. If the condition is aggravated, the diseased cattle will be visually impaired and even blind. Muscle weakness, unstable standing, walking shaking, or cramps on the ground. The heart beats faster, the pulse is weak, and I don't feel it in the hand. Dyspnea, yellow-white and reddish small foam-like nasal fluid flowed from the nasal cavity. Chest auscultation, with a wide and deep wet sound, and eventually died of heart failure.

How to prevent and cure cottonseed cake poisoning:

(1) Prevention

Limit feeding: feed undetoxified cottonseed cake, no more than 1.5 kg per day. In order to avoid cumulative poisoning, it should be fed for half a month and stopped for half a month. Pregnant cows and calves should not be fed.

Heating detoxification: when pressing oil, it is best to change free gossypol into combined gossypol through the process of stir-frying and steaming; raw cottonseed skin and cottonseed residue should be boiled for 1 hour before feeding; cottonseed should be dried, removed from soil, crushed and washed with clean water after fermentation. then soak in lime for 10 hours before feeding.

Add iron to detoxify: the cottonseed cake is soaked in 0.1% or 0.2% ferrous sulfate solution, and the gossypol failure rate can reach 81.81%. Ferrous sulfate can also be added to the feed according to the ratio of iron to free gossypol at 1:1, but iron and cottonseed cake should be fully mixed to increase the contents of protein, vitamins, minerals and green feed in the diet, which is also good for preventing cottonseed cake poisoning. If you mix the same amount of soybean cake with cottonseed cake, or 5% soybean cake, add 2% fish meal, or 4% fish meal mixed with cottonseed cake. Cultivate cotton varieties without gossypol.

Treatment:

There is no specific antidote for this disease. Once poisoning occurs in cattle, general detoxification measures can only be used for symptomatic treatment.

Improve feeding: if poisoning is found, stop feeding cottonseed cake immediately, stop feeding for 2 days, give green succulent feed, and give sufficient drinking water, and eliminate gastrointestinal contents: gastric lavage or enema can be carried out with hydrogen peroxide or potassium permanganate solution of 1, 000 and 5000, and 3% sodium bicarbonate solution of 5% bicarbonate; take salt laxatives such as sodium sulfate or magnesium sulfate 400 grams 800 grams.

For diseased cattle with hemorrhagic gastroenteritis, antidiarrheal and serous agents can be used, and 500-5000 ml 1% acid solution can be taken internally. Ferrous sulfate 7g / 15g, one oral dose. In order to protect gastrointestinal mucosa, you can take 250 grams of lotus root powder and flour, rinse into a thin paste of boiling water, and take it twice a day.

Detoxification, liver protection, cardiotonic and anti-exudation can be done with 25% glucose solution 500 ml / 1000 ml, 10% sodium coffee 20 ml, 10% calcium chloride solution 100 ml, once intravenously, twice a day. The combination of vitamin C, vitamin An and vitamin D has a certain curative effect.

Excite pre-gastric movement and promote gastrointestinal toxicant excretion. Cholinergic drugs can be used, 0.2-0.3 grams of pilocarpine are injected under the cowhide.
