Release time:
2018-07-25
The most common cause of summer cattle is high temperature and humidity in summer and autumn rainy season. Especially after flood disaster, all kinds of grain feed, animal and plant high protein feed, fermented silage and overharvested grass and vegetables are not easy to preserve. Feed is easy to be affected with damp, especially the feed soaked in water, which is more likely to deteriorate, mildew and rot. Decayed feed contains Clostridium botulinum, such as cattle and other animals eat these rotten forage and drink spoiled drinking water, which contains Clostridium botulinum will multiply in cattle, produce metabolites with toxins, and cause a human, livestock, poultry zoonotic acute food toxemia, also
What diseases do cows get most easily in summer?
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, which 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.
This disease in livestock to cattle and sheep, horses, the most common, pigs, again for poultry. In the current season, farmers should pay more attention to prevent the occurrence of the disease.
1. symptoms:
In the most acute cases, cattle often die suddenly without any symptoms.
② Acute disease cattle are characterized by paralysis of lips, tongue, throat, etc., and often have sudden dysphagia. Although they have perception and reflex, they have motor paralysis, which develops from the head to the hindquarters and to the limbs. They often lie down and cannot stand up. The head is distorted to one side, showing sleeping pupils, dilated holes, soft neck, stomach and femoral muscles, and finally they do not eat or drink, exposed tongue and saliva, dung dry, abdominal pain, often died on the same day, some delay 4 to 5 days.
③ 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.
2. prevention:
In view of the fact that the disease has the characteristics of rapid onset and rapid death, we should not passively grasp the treatment alone, but should prevent more than cure, and fight the active battle in order to achieve good results in prevention and treatment.
① Cattle should be carefully fed. Cattle should not be fed with rotten grass, materials, 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.
② In terms of environmental management, the garbage in the field should be cleared at any time, the dead animals should be strictly disposed of, and the disinfection should be thorough. In particular, we must do a good job of rodent control to prevent pollution of aquatic plants and grain feed.
③ Lodge licking bricks freely lick to supplement calcium, phosphorus, salt and trace elements required by cattle and sheep to meet the needs of cattle and multiple nutrients. Prevent the emergence of cattle pica, so as not to drink dirty water, lick spoiled feed.
④ Found sick cattle, diagnosed as soon as possible, early intravenous or intramuscular injection of polyvalent Clostridium botulinum antitoxin serum, adult cattle 500-800 ml, or injection of the corresponding type of antitoxin monovalent serum treatment, have certain effect.
⑤ Gastric lavage, enema or lavage should be carried out as soon as possible, and quick-acting laxatives can also be infused intravenously to reduce toxin absorption and expel toxins from cattle. Then perfuse alum water or formalin solution to disinfect the astringent intestine.
The drug treatment can use guanidine hydrochloride and so on. Some people advocate the use of sedatives and anesthetics for sick cattle, which has a certain deterrent effect on the disease.
⑦ Intravenous injection of 10-40% urotropine sterilized aqueous solution can be decomposed into ammonia and formic acid, so it has antibacterial effect, can be used to treat complicated pneumonia, and has diuretic effect. Excitement, cardiac detoxification, can use 20% sodium caffeine injection, 20 ml each time, subcutaneous or muscle to shoot.
⑧ Strengthen the care of sick cows. When sick cows with chewing and swallowing difficulties cannot eat, they can inject glucose solution or normal saline intravenously to maintain the physical strength of sick cows and promote recovery as soon as possible.
