What if the ewe's breasts are red and swollen and have lumps? How to treat ewe mastitis?
After the ewe is produced, it begins to secrete milk. However, due to improper operation, the ewe's breast is infected with germs, which is prone to mastitis. If it is not treated seriously, it will be life-threatening. The following is the cause, symptoms and methods of prevention and treatment of ewe mastitis.
(1) Causes
Ewe mastitis is caused by improper milking methods, damage to the nipple, breast gland, grazing, shrub the skin of the breast when feeding, germs infected through the breast hole or wound; improper care of the ewes, poor sanitation to create bacteria to invade the breast The conditions. The main pathogens are Staphylococcus, Streptococcus and Enterobacter. Some infectious diseases such as foot-and-mouth disease and actinomycosis can also cause mastitis. The disease is caused by high milk yield and long-term feeding of sheep.
(a) symptoms
Acute type of goat's milk area is characterized by fever, pain, redness and swelling. The breast lymph nodes are swollen, the milk becomes thin, mixed with floc or granules, sometimes mixed with pus, blood, and the milk is dark yellow or with red. Watery mucus. And with varying degrees of systemic symptoms, such as loss of appetite, stagnation of sputum, body temperature increased by 41 ~ 42 ° C, breathing, pulse speed, hind limbs walking while walking. Some show arthritis and keratitis. Later, the breast becomes more swollen and there are many small hills in appearance, until the pus is ulcerated and the tissue of the breast is necrotic. The sharp weight loss of the diseased sheep often succumbs to sepsis. It is chronic when it is not completely cured. Chronic cases often have no systemic symptoms, and the elasticity of the tissue in the milk area is reduced. There are lumps of varying sizes in the breast, and the milk is significantly reduced or unable to squeeze out the milk.
(three) treatment
In the early stage of the disease, the effect of injecting antibiotics into the breast is good. After the milking, the disinfected milk duct is gently inserted into the nipple hole, and 400,000 units of penicillin and 0.5 g of streptomycin are dissolved in 5 ml of water for injection. After the injection, gently tap the glandular part of the breast to distribute the drug evenly. Penicillin procaine blocking therapy can also be used to inject the drug into the base of the breast for closed treatment.
In order to promote the absorption of inflammation, first apply cold for 2 to 3 days and then apply hot. It can be heated to about 45 °C with 1000 ml of 10% magnesium sulfate aqueous solution, and applied once or twice a day for 4 times. For suppurative mastitis, the pus should be drained and then disinfected with 3% hydrogen peroxide or 0.1% potassium permanganate water, and then drained with 0.1% to 0.2% Rayvernol gauze. At the same time, antibiotics for systemic treatment.
After mastitis in lactating ewe, we should promptly find the lactation ewes or artificial breastfeeding for the lambs to prevent the lambs from causing the disease through the infection of the milk. Ewes suffering from mastitis should be treated early to prevent conversion to chronic mastitis. Treatment is divided into topical treatment and systemic treatment.
(1) In the early stage of acute mastitis, cold compressing and then squeezing the milk, using 0.25% to 0.5% procaine 10 ml plus 400,000 units of penicillin, multiple injections in the breast tissue. Or use 400,000 units of penicillin and 0.5 g of streptomycin diluted with water for injection and then injected into the milk hole. After 2 to 3 days, hot compress therapy can be used. 1000 ml of 10% magnesium sulfate aqueous solution is usually used, and heated to about 45 ° C for 1 or 2 times a day for 5 to 10 minutes for 2 to 4 days.
(2) Perform breast irrigation and perfusion. First squeeze the bad milk into the milk tank with 50 ~ 100 ml of normal saline, gently massage and squeeze out and wash 2 to 3 times. Finally, 200,000 units of penicillin dissolved in 40-60 ml of physiological saline was injected into the milk pool 2 to 3 times a day.
(3) Hemorrhagic mastitis is prohibited from gently squeezing out blood milk, and injecting 200,000 units of penicillin into the breast with 0.25% to 0.5% procaine 10 ml. If there is a blood clot in the milk pool, 50 ml of 1% saline can be injected through the teat canal to dissolve the blood clot.
(4) Suppurative mastitis and abscesses that are deep in the mouth should be drained first, then rinsed with 3% hydrogen peroxide or 0.1% potassium permanganate solution, and then drained with 0.1% to 0.2% of the Lefnoor gauze strip. Give systemic antibacterial therapy.
2, systemic treatment of sick sheep when the body temperature rise can be fed sulfa drugs, the amount is calculated according to 0.07 g / kg body weight, 4 to 6 hours, the first dose is doubled; or intravenous injection of sulfadiazine sodium 20 ~ 30 ml, Once a day; intramuscular injection of penicillin, 200,000 to 400,000 units each time, 2 to 3 times a day.
In addition, during the treatment period, the lactation function of the ewe should be temporarily stopped. The diet reduction method can be adopted, that is, the feed amount of the concentrate is reduced, and the succulent feed such as silage, root vegetables and barley feed is less, and the drinking water is restricted. Mainly fed to high quality hay, such as alfalfa, clover and other legumes.
(4) Prevention
Good sanitation and milking methods are key to preventing this disease. When milking the sheep, use a clean warm water and a towel to scrub the breasts. Exfoliate the milk to check for abnormalities. For milk sheep, it is necessary to milk milk 2 to 3 times a day. Some ewes have higher milk yields, and the lambs must be squeezed out of the remaining milk. Usually pay attention to prevent breast injuries. Ewes with excessive breast swelling before delivery should reduce the amount of concentrate and juicy material.
Ewe mastitis is very harmful to the health of the ewes, and even threatens the life, causing economic losses to the farmers. Moreover, the ewe is suffering from mastitis and is no longer suitable for breastfeeding, and has an effect on the growth of the lamb. Farmers should pay attention to the health problems of the ewes and do a good job in prevention and treatment.
