How to prevent milk sheep mastitis in low temperature season
Winter is the season of high incidence of milk goat diseases, especially milk goat mastitis, which is a very harmful disease. It reduces milk production, causes waste of feed and increases drug costs, and bring huge losses to dairy production.
Mastitis in dairy goats is divided into 4 types, namely the most acute type, acute type, subacute type and chronic type.
The most acute type of infection has obvious redness, swelling, heat, and pain in the breast area, and the affected sheep is extremely depressed, with increased body temperature, poor appetite, and weight loss.
Acute breast enlargement, flushing of the skin, slightly high body temperature, decreased appetite, decreased lactation, and some even unable to express milk, the milk is turned yellowish-white, yellow-brown or slightly reddish, with varying sizes of viscous Sexual clots, found not to transform into chronic mastitis in time.
There is no obvious change in subacute breasts, but there will be a slight clot in the milk, especially a few drops of milk that has just been squeezed.
Most of the chronic type is from the acute type, the incidence is relatively high, and most sick sheep will have repeated attacks. There are lumps or flocs in the milk, and milk production decreases. There are floccules in the milk that has just been expressed, and it gradually becomes watery (clear and slightly yellowish), and the final milk that is expressed is the normal color.
After repeated attacks, the breasts will appear lumps and the nipples will become hard, making it difficult to express milk. Some diseased areas will shrink, form pus, and eventually develop sepsis and die. The disease lasts for several months.
Comprehensive prevention measures
1. Establish and improve the mastitis inspection system to prevent diseased sheep from entering the flock to spread. The sheep to be purchased shall be checked for mastitis on the spot, and the sick sheep shall be detected in time. The sheep that are shipped back can be mixed only after several weeks of isolation and observation to confirm that they are not sick.
2. The prevention of the disease should mainly be based on its cause and strengthen feeding management. Keep the sheep barn dry and clean, strictly clean and disinfect; avoid breast trauma, prevent herders from beating the sheep with whipping; in high-cold areas, prevent frostbite udders in cold weather. Cut off the dirty hair around the breasts before giving birth to reduce the chance of infection. If possible, clean the breasts with disinfectant water before the sheep is ready for delivery. Eliminate sick sheep suffering from chronic mastitis to prevent infection of healthy ewes.
3. The prevention and treatment of dry milk is an effective measure to control mastitis, which can reduce the incidence of mastitis to a large extent. This method can not only treat a sheep with latent mastitis in the lactation period, but also reduce the incidence of the next lactation period. The drugs used to prevent and treat mastitis during the dry period should have a broad sterilization spectrum and have a long-lasting effect in the breasts to kill the pathogenic bacteria that have invaded.
In short, comprehensive control measures should be taken for the disease. Do a good job of daily feeding management and prevention work, that is, regularly disinfect the shed during the lambing season, disinfect the utensils, do a good job of nursing care, and treat the sick sheep in time, so as to effectively control the occurrence of the disease.
