Feeding cattle to add licking brick free licking trace elements to meet the needs of cattle a variety of nutrients. To prevent the appearance of cattle pica.
Into the summer and autumn rainy season, is the beef toxin Clostridium(Also known as salami bacillus)Multiple periods of poisoning. Because of the high temperature and high humidity in the rainy season in summer and autumn, especially after floods, all kinds of grain feed, high protein feed for animals and plants, fermented silage and overharvested grass and vegetables are not easy to preserve, and the feed is easy to get damp, especially the feed that has been soaked in water, is more likely to deteriorate, mildew and rot. Clostridium botulinum is contained in rotten feed. For example, cattle and other animals eat these rotten forage and drink spoiled drinking water. The Clostridium botulinum contained in it will multiply in the cattle and produce toxic metabolites. It causes an acute food toxemia that is common to humans, animals, and poultry, also called Clostridium botulinum or botulism. In the current season, farmers should pay more attention to prevent the occurrence of the disease.
In the most acute cases, cattle often die suddenly without any symptoms.
Acute cattle are characterized by paralysis of the lips, tongue, throat, etc., and often have sudden dysphagia. Although they have perception and reflexes, they have motor paralysis, developing from the head to the hindquarters and to the limbs. They often lie down and cannot stand up. Their head is distorted to one side, showing a sleeping pattern, dilated pupils, soft neck, stomach and femoral muscles, and eventually they do not eat or drink, exposed tongue and saliva, dung dry, abdominal pain, often died on the same day, also have delayed4-5The course of the day.
The chronic disease cow is the same as the acute disease. Due to the long course of disease, pneumonia and heart failure are often complicated until the cow is thin and dead.
prevention and control method
In view of the fact that this disease has the characteristics of rapid onset and rapid death, we cannot simply grasp treatment passively. Prevention is more important than treatment, and we must take the initiative to fight in order to achieve good results in prevention and treatment.
1Cattle should be carefully fed, and cattle should not be fed with rotten grass, feed, vegetables and other feed at will, because mildew and rotten feed can often cause a large number of bacteria to multiply and produce toxins. Therefore, it is not possible to save feed and lose the big because of the small, resulting in irreparable economic losses.
2In terms of environmental management, the garbage in the field should be cleared at any time, and the dead animals should be strictly disposed of. They should not be littered and thoroughly disinfected. In particular, we must do a good job of rodent control to prevent pollution of aquatic plants and grain feed.
32. The silage fed in the newly opened cellar should be managed and sealed well without rain leakage or water inflow to prevent the silage from deteriorating and mildew. When making silage in summer and autumn, it is necessary to ensure the quality, prevent dead mice or dead cats and rotten dogs from being mixed, cut off the spread of Clostridium botulinum, and keep the disease from entering through the mouth.

5In all areas where Clostridium botulinum has occurred, regular vaccination of Clostridium botulinum vaccine should be done to obtain immunity and ensure the safe production of cattle.
6, found sick cattle, diagnosed as soon as possible, early intravenous or intramuscular injection of polyvalent Clostridium botulinum antitoxin serum, into cattle500-800mlOr injection of the corresponding type of antitoxin monovalent serum treatment, there is a certain effect.
A toxin neutralization test must be performed first, because Clostridium botulinum isA,B,C,D,E,Ftype six,CType is dividedCaandCbTwo subtypes, each type of toxin produced, can only be neutralized by the same type of antitoxin, suchDtype toxin can only beDNeutralized by type antitoxin. In the known poisoning is caused by which type of bacteria, you can make the toxin neutralization test.
7Should be carried out as soon as possible gastric lavage, enema or lavage quick-acting laxatives, can also be intravenous infusion, reduce toxin absorption, excretion of toxins in cattle. Then perfuse alum water or formalin solution to disinfect the astringent intestine.
8, drug therapy can use guanidine hydrochloride andVEMonoacetic acid ester, etc. Some people advocate the use of sedatives and anesthetics for sick cattle, which has a certain deterrent effect on the disease.
9Intravenous injection10-40%Urotropine sterilization aqueous solution, can be decomposed into ammonia and formic acid, it has antibacterial effect, can be used to treat concurrent pneumonia and diuresis. Excitement, cardiac detoxification, available20%Sodium sodium coffee injection, each time20mlsubcutaneous or intramuscular injection.
10Strengthen the care of sick cattle, chewing and swallowing difficulties of sick cattle, can not eat, intravenous injection of glucose solution or physiological saline. In order to maintain the physical strength of the sick cattle, to promote recovery as soon as possible.
