First, health management
1. Drink clean water. Under normal circumstances, a lactating dairy cow can only ensure the normal metabolism of the bovine body when the amount of drinking water reaches 100 kg in the summer, and maintain normal physiological function to meet the production needs. Therefore, it must be ensured that there is sufficient clean drinking water in the water tank, and after each drinking water, the remaining water is cleaned, the water tank is washed, and fresh water is put again.
2. Feed fresh ingredients. It is forbidden to feed mildew and fodder with dirty water. In the silage feeding mode, it is possible to feed while feeding, less feed, and brush the food trough once a day.
3. Keep the barn clean. It is necessary to clean the barn and eliminate manure and waste. Do a good job of ventilation and keep the cow house clean, dry, and cool. It is necessary to wash the cow bed regularly with fresh water on a regular basis and regularly disinfect it to ensure the quality of cleaning and disinfection. Weekly routinely sterilize the outer environment of the barn, including sheds, venues and utensils, equipment, drainage channels, sewers, water tanks, food troughs, and bovine whole body tables with 5% of the children. Cowsheds and sports fields can be sterilized with 3% sodium hydroxide solution, and some grass ash or lime powder can also be used to disinfect, deodorize and remove moisture to reduce the occurrence of diseases.
4. Clean the cow body. Every day before milking, use a soft brush from top to bottom, brushing the body from front to back 1 or 2 times. For hard mud that is difficult to brush off, first use blisters, and then brush to clean the cow body and keep the body clean.
5. Get rid of parasites. In order to prevent mosquitoes from biting the bovine body and spreading diseases, ivermectin can be administered at a dose of 0.2 mg/kg body weight, and once again at the same dose at intervals of one week, in order to drive out the parasites in the cow. Regular use of anti-mosquito spray to regularly spray the body of cattle, kill mosquitoes and flies, to provide cattle with a quiet place to rest.
Second, health measures
1. Breasts should be cleaned. Strengthen milking hygiene and strictly enforce the milking operation procedures. The first procedure after milk cows enter the milk parlour is to clean the breasts. When cleaning, the milker should first rinse the dirt, rags and other dirt from the hindquarters of the cow and then stand. On one side of the cow, use a wet towel to wash the nipple, wash the breast, and then stand on the back of the cow. Hold the cow's ischia with one hand, scrub the cow's breast mirror with one hand, both sides of the breast and the inner sides of both thighs, and then twist the towel. After dry, wipe each part of the breast. After the breast cleaning, milking on the machine and promptly carrying out a medicinal bath after each milking can effectively reduce the incidence of mastitis in dairy cows. The method is to soak the nipple in a chyhexite bath containing 4% sodium hypochlorite, 0.3% to 0.5% chlorhexidine, or 0.5% to 1% iodine attached for 30 seconds. In addition, the milking room should be cleaned in time for milking equipment, and regular determination of somatic cells in barrel milk and cows should be performed. Based on the number of somatic cells, the prevalence of subclinical mastitis should be judged and corresponding measures taken.
2. Four limbs to care. Wash the hooves twice a month with clean water and apply 10% to 15% copper sulfate or zinc sulfate solution after washing. The cow's fork hoofs, clefthoofs, etc. are trimmed in time to prevent hoof wounds. Periodic inspections of the hoofs revealed that the limbs were immediately isolated, flushed with saline, and disinfected with neo-Gilbo, and then rot tissues were removed for bandaging, as well as drug closure and acupuncture treatment.
3. The uterus should be checked. After the production of cows, attention should be paid to the shedding of the placenta and the discharge of lochia. The genital organs should be examined 15 days after childbirth and problems should be discovered and promptly treated. The delivery cow timely feeds brown sugar wheat bran soup or ginger water to promote the discharge of the placenta. Cows detained in the placenta were fed with clear uterine fluid in time and the uterus was flushed several times to avoid secondary uterine inflammation. Check the uterine placenta exclusion within 2 to 3 days after childbirth, and perform uterine health care within 4 to 6 days after childbirth.
4. The epidemic should always be guarded against. Right-time immunization of Japanese encephalitis and foot-and-mouth disease is performed regularly, and brucellosis and tuberculosis are detected and purified regularly. Each month and a half, the injection of cockroach-killing drugs was performed to reduce the risk of summer pestiosis.
5. Summer heatstroke. Appropriately reduce the breeding density of the cows in the house, install high-power exhaust fans, and promote air flow. In the absence of shaded trees, a shade net should be set up on the sports ground to prevent cows from getting sun exposure. In the case of high humidity and high heat, the cattle should be given 20ml of Huoxiangzhengqi water at 10 o'clock in the morning and the vitamin C5 to 10g at 4 o'clock in the afternoon to prevent heat stroke.
