What is the most common disease for dairy cows? 

Posted on: December 9, 2019, by Eleanor

There are currently about 220 million dairy cows in the world, and about one-third of them have various types of mastitis, and the annual loss due to mastitis is as high as $35 billion. In production, cow mastitis leads to a decrease in milk production, a decline in the quality of fresh milk, and the elimination of inflammatory milk. In severe cases, the milking area is purulent and sputum, which causes the cow to lose its ability to lactate. The following is a brief introduction to the diagnosis and treatment of dairy cow mastitis and hopes to benefit the majority of dairy farmers.

Dairy cow mastitis is a common and complicated disease that causes the most serious economic loss in the dairy industry. It is also one of the common diseases in dairy farming.

Clinical mastitis is easier to diagnose based on its clinical symptoms. Diagnosis of specific pathogens requires isolation and culture of bacteria, biochemical experiments, and animal pathogenicity experiments. The diagnosis of recessive mastitis is due to changes in the milk composition of recessive mastitis, so it is possible to diagnose the recessive mastitis by examining the milk. Latex cell check. 

After the breast infects the bacteria, the bacterial metabolite induces the polymorphonuclear leukocytes to enter the mammary gland cells, and the damaged epithelial cells also enter the milk, which increases the number of somatic cells in the milk, especially the number of white blood cells. Therefore, it can be determined whether the cow has recessive mastitis by detecting the number of somatic cells in the milk.

Other methods of detection include breast disk test, milk conductivity method, simple diagnostic liquid method for mastitis, cell ATP content determination in milk, Nagase method, bovine milk enzymology test, lactate dehydrogenase in milk, glutamic acid propionate Acid transaminase, serum albumin content determination, microbiology culture, SMT reagent diagnostic method and immunological diagnosis.

Dairy mastitis prevention and treatment program

Making a good environment. Poor environment for bovine health is a place for microbial growth and reproduction, and an important way to infect mastitis. Therefore, maintaining good environmental hygiene and preventing bacterial reproduction is the key to prevention. The barn and sports ground should be clean and dry, and the manure, water, and mud should be cleaned in time. The bedding should be dry, soft, clean, fresh, and replaced frequently. It is necessary to disinfect the sports ground and the barn regularly (it can be disinfected once every 15 days with disinfectant spray), and the disinfection should be strengthened during the high season of mastitis. Guarantee a clean and hygienic environment.

Improve the environment of the barn, so that the house is well ventilated and positive. Brush the car often and keep your breasts clean. For larger breasts, especially sagging breasts, care should be taken to protect them from trauma. Cattle breeders should pay attention to postpartum care, and discharge the lochia as much as possible to reduce the hindquarters of the polluted carcass. Do a good job of summer heat preservation in summer, reduce stress response, and make cows live in a comfortable and quiet environment.

Strengthening feeding management. According to the nutritional facts needs of dairy cows, it is important to pay attention to standardized feeding, give full-price rations, and mix the fine and coarse feeds in each production stage in reasonable and comprehensive supply, establish a green and succulent feed rotation system, and increase the feeding amount of green and silage. , with milk to make up the material, according to cattle feed. Disable metamorphic feed to maintain the optimal physiological function of the body.

Cattle farmers should pay attention to the filling and contraction of the breast after stopping the milk, and find that the abnormality should be checked immediately; in the late period of breast-feeding and before delivery, the feeding amount of succulent feed and concentrate should be appropriately reduced to reduce the swelling of the breast; When the breast is over-expanded, in addition to the above measures, milking should be increased 1 or 2 times as appropriate to control drinking water and increase the number of grazing.

Diagnosis and treatment of cow mastitis:

Eastern cow Gongrukang 1000g-2000g is added to every ton of feed. It can replace antibiotics to reduce T cells, treat mastitis, clear heat and detoxify toxins, anti-bacterial and anti-inflammation, dredge collaterals and lower breast, activate blood circulation and disperse stasis, relieve swelling and disperse carbuncles, treat both symptoms and symptoms, especially for recessive mastitis. The cure rate is higher than 90%.
