Prevention and treatment of Dairy Cow Diseases

High yield, stable yield and health are the goals that dairy cows want to achieve, in which health is the key. Only when dairy cows are healthy can there be high yield and stability of dairy cows. Due to the change of the environment and the negligence of feeding management, the disease of dairy cows is inevitable. The important thing is how to reduce the occurrence of the disease and the loss caused by it to the minimum. For a dairy farm with good feeding technology and high level of management, the goal of disease control should be: (1) the annual total elimination rate is 25% Muth28%; (2) the annual mortality rate is less than 3%; (3) mastitis treatment techniques should not exceed 1% of dairy cows; (4) the mortality rate of calves within 8 weeks of age is less than 5%. (5) the mortality rate and elimination rate of bred cattle are less than 3%; (6) the abortion rate of pregnant cows in the whole year does not exceed 8%. The health of cattle should have a definite health care plan, and the key lies in early prevention, correct diagnosis and effective treatment of the disease. Prevention: prevention should be based on preventive medicine, and its measures include nutrition, disinfection, isolation, diagnosis, elimination and immunization. Nutrition is the material basis of dairy cow health and the fundamental guarantee of body health. Reasonable feeding and balanced diet can enhance the resistance of the body; malnutrition not only directly causes nutritional and metabolic diseases in dairy cows, but also susceptible to other diseases. The regular cleaning and disinfection of the cattle farm environment, especially before and after calving, can reduce the growth and reproduction of environmental microorganisms; the isolation of diseased cattle, or the purchase of cows from other dairy farms, carry out the necessary health examination and isolation (2-3 weeks). Can greatly reduce the spread of disease between individual cows and herds. Strict epidemic prevention and timely elimination of diseased cattle suffering from tuberculosis, brucellosis and foot-and-mouth disease is an effective way to eliminate the source of infection and prevent its epidemic. Second, diagnosis: accurate and rapid diagnosis of the disease is an important part of recovering the loss. Without timely and accurate diagnosis, there will be no effective treatment. Simple and effective methods should be adopted in clinical diagnosis, and medical records should be established to constantly sum up clinical experience. Clinical examination should combine general examination (including mental walking examination, skin examination, eye conjunctival examination, body surface lymph node examination and body temperature measurement, etc.) and systematic examination (including pulse, respiration, appetite, ruminant, fecal urine, reproductive organs, breast changes). Pathological examination and laboratory examination can also be carried out when conditions permit.
