Cows' lactation and longevity directly affect the economics of dairy farms. Doing health care work on the cow's udder can increase its milk production and reduce the incidence of mastitis and increase the useful life of dairy cows.
1. Keep a quiet milking environment. Wash the breasts and nipples sequentially with warm water of 45°C-50°C and dry them from top to bottom.
2. The breast should be massaged after it is washed so that it can be milked after it has been inflated. Machine milking, vacuum pressure should be controlled at 350 mm -380 mm Hg, pulse beater control at 60-80 times per minute, to prevent emptying.
3. The milk must be squeezed. After the milk is squeezed clean, the breasts are wiped off and the teats are soaked with 3%-4% sodium hypochlorite or 0.5%-1% iodine.
4 before and after the use of milk must be thoroughly cleaned. Wash first with cold water, then rinse with warm water, then scrub with 0.5% hot alkaline water, and finally wash with clean water. The rubber product is cleaned and soaked in disinfectant.
5. Disinfection of milker inner sheath. The inner sheath of the milker was disinfected once a week, boiled with 0.25% caustic soda solution for 15 minutes, soaked for 1 night, and dried for later use. The teat cup is washed daily with hot water above 85°C. If the inner sheath can not be boiled, it can be soaked in 5% caustic soda solution and dried.
6. First squeezing a healthy cow and then squeezing the sick cow. For cows born within 10 days of contracting cows suffering from mastitis, they must be squeezed by hand. Diseased cow milk can not be squeezed in the cow bed, it is necessary to focus on treatment.
7. Recessive mastitis detection. Cows who want to stop milk should be tested for recessive mastitis 10 days before breastfeeding to treat positive cattle.
8. Do a good job of prevention. When breastfeeding, each breast area is injected with antibiotics once. One week before delivery, the medicine bath nipples are taken twice a day.
9. Symptomatic treatment of sick cattle. The clinical mastitis disease cow should be isolated from the herd and fed separately; milk barrels and towels should be used exclusively; after use, it should be disinfected; the diseased milk should be discarded after being disinfected; timely treatment should be performed, and the cattle should be returned to the village after recovery.
10. Timely elimination of serious cows. For diseased cows suffering from refractory mastitis, they should be eliminated in time.
