Prevention and treatment of obese cow syndrome after ineffective treatment of appetite abstinence drugs

Obese cow syndrome is actually a metabolic disorder caused by calving stress in cows after long-term malnutrition. After the disease, the curative effect is poor, so comprehensive prevention and treatment should be taken. Obese cow syndrome is often caused by improper feeding and management. Such as single feed variety, too much concentrate, lack of roughage, lack of exercise, etc.; mixed feeding, the diet is not adjusted according to the physiological stage; cows in the dry period, feed energy is too high, resulting in digestion, metabolism, reproduction and other functional disorders. The symptoms can be divided into acute and subacute.

Cow

Acute: the cow developed with childbirth, loss of appetite, lack of milk or no milk, visible mucosal cyanosis and yellow staining, body temperature of 39.5 ℃ ~ 40 ℃, stiff gait, dull eyes and weak reaction to the outside world. Those with diarrhea symptoms, yellow, malodorous and sparse feces, no response to drugs, 2-3 days after onset, lying on the ground can not afford, or even death.

Subacute: more than 3 days after delivery, mainly showing ketosis, loss of appetite or abstinence, sudden decrease in milk production, less and dry feces, ketone taste in urine, positive ketone body reaction, accompanied by mastitis, placenta, relaxation of uterus, accumulation of brown rotten lochia in the birth canal, ineffective drug treatment, lying on the ground, moaning, molars.

Prevention and control measures: prevention first, comprehensive prevention and control.

1. Strengthen feeding management and supply balanced diet. Dry cows limit the amount of concentrate and increase the amount of hay. Raise in groups and feed dry cows and lactating cows separately.

two。 Strengthen cow health check. Strengthen the antenatal and postpartum health examination of cows and establish a ketone body monitoring system to detect diseased cows early. If the ketone body reaction is positive, it should be treated immediately. Regular sugar and calcium supplements were given to cows with old, high yield, loss of appetite and history of ketone disease. 500 milliliters of 20% glucose solution and 20% calcium gluconate solution were injected intravenously one week before delivery.

3. Mating in time. Timely breeding of cows, do not miss estrus cows, improve the conception rate of cows, prevent cows from being obese due to long dry milk period.

4. medication. The purpose of drug therapy is to inhibit fat decomposition, reduce the accumulation of fatty acids in the liver, accelerate the decomposition and utilization of fat, and prevent ketosis. Its principle is detoxification, liver protection, sugar supplement. Each cow can be intravenously injected with 50% glucose solution 500 ml 1000 ml, or 50% dextran, 1500 ml at first, and then 500 ml 2 times 3 times a day. Nicotinic acid can also be taken orally, 12-15 grams per cow, once a day for 3-5 days. Propylene glycol can also be taken orally, 170-342 grams per cow, twice a day for 10 days. To prevent secondary infection, broad-spectrum antibiotics, such as 200-2.5 million international units of chlortetracycline or tetracycline, can be injected intravenously twice a day.
