Treatment of mastitis in dairy cows

Cows are born to produce milk, so what if they get cow mastitis? How to treat, how to prevent cow mastitis?

Treatment of mastitis in dairy cows

1. Antibiotic therapy

Antibiotics are an effective means for the prevention and treatment of dairy cow mastitis, especially in the treatment of acute, multiple and subacute mastitis, controlling the quality of milk products or as an important part of comprehensive prevention and treatment. However, with the widespread use of antimicrobials, there are more and more drug-resistant strains, which reduces the efficacy of commonly used drugs, especially for Staphylococcus aureus. Flunone is a new type of chemical synthetic drugs, which has the characteristics of wide antimicrobial spectrum, strong antibacterial activity, wide distribution in vivo, little side effects and no cross-resistance with other antibiotics. Semi-synthetic penicillins such as ampicillin and sulbactam sodium mixture have high bioavailability, especially acid-resistant and enzyme-resistant, broad antibacterial spectrum and strong effect on drug-resistant Staphylococcus aureus. When injecting the drug, under the condition of disinfecting the milk duct, nipple and the operator's hand, first squeeze the milk from the affected area, and then inject the drug through the papillary tube.

2. Blocking therapy

First, systemic blockade, such as 0.25 Mel 0.5% procaine 200-300ml intravenous injection, to relieve pain in the affected breast area and accelerate the metabolism of inflammatory foci.

The second is partial closure. The perineum is closed and the oxtail is pulled to one side and sterilized at the junction of the labia. Push the lower commissure with the left hand and touch the ischial notch; hold the needle with the right hand, puncture along the center of the ischial notch, depth 15-20cm, inject 3% procaine 15-20ml. The base of the breast is closed. If the breast area is closed, push the milk lobe forward and downward first, the needle is on the front side of the milk lobe (the junction between the side of the milk lobe and the front), and in the groove formed between the breast and the abdominal wall, the 8-10cm is inserted along the abdominal wall in the direction of the contralateral knee joint, and 0.25% nouvacaine 150-200ml is injected into each leaf. If the needle was closed in the posterior 1pm 4 breast area, the needle was inserted at the side of the intersection between the midline of the breast and the posterior edge of the base of the breast, along the abdominal wall forward and downward, toward the ipsilateral wrist joint, the depth of 8-10cm was the same as that of the anterior lobe.

3. Chinese herbal medicine therapy

The problem of drug residues in dairy products has attracted more and more attention. Chinese herbal medicine, as a natural medicine, has relatively less toxic and side effects than chemical drugs, and many Chinese herbal medicines are good immunomodulators. Chinese herbal medicine has the efficacy of clearing heat and detoxification, detumescence and dispersing knots, promoting blood circulation and removing blood stasis, and dredging breast under menstruation in the treatment of mastitis.

4. Physiotherapy

The aim is to reduce inflammatory exudation and promote exudate absorption, anti-inflammation and analgesia.

(1) Hot compress, once in 30 minutes, 2 Mel 3 times a day, in order to improve blood circulation and promote the absorption of inflammatory substances.

(2) Infrared or ultraviolet therapy, irradiate the affected area with "Weikang Lamp" (divided into 5 points, each point for about 5 minutes, about 30cm from the affected area), twice a day, 30 minutes each time, combined with Chinese herbal medicine. The patients were treated with the above two methods and were cured in 7 days.

(3) Laser therapy: irradiated by he-ne laser, low-power he-ne laser can dilate blood vessels, dredge channels and collaterals, promote blood circulation, accelerate metabolism and enhance body resistance.

(4) Breast massage is performed 3 times a day, 10 cents per day for 15 minutes. Serous mastitis from bottom to top, catarrhal mastitis and suppurative mastitis from top to bottom, but cellulose, hemorrhagic, honeycomb inflammatory mastitis taboo massage.

(5) increase milking times to eliminate spoiled milk, pathogens and bacterial toxins. Reduce the stimulation to the breast and the spread of pathogens.

5. Surgical treatment

For suppurative mastitis, such as shallow abscess, it is appropriate to cut and discharge pus, and for deep abscess, pus should be extracted first, and then injected with antibiotics.

6. Nipple medicine bath

Nipple medicine bath can kill the pathogenic bacteria in nipple end and papillary tube, which is an effective way to prevent and cure mastitis. The solution for soaking nipples requires strong bactericidal, low irritation, stable performance and low price. The commonly used drugs are Xian Bitai, bromogeramine and so on. Among them, 0.3% chlorhexidine has the best effect. After each extrusion, soak the nipple in the liquid medicine, but stop using it in the cold and dry winter to prevent chapped nipples or frostbite.

7. Trial of antiparasite drugs

Levamisole hydrochloride is an insect repellent and has immune activity. It is effective in the treatment of recessive mastitis in dairy cows, the positive rate of recessive mastitis is reduced from 42% to 8%, and the cure rate is up to 80%. The results show that levamisole hydrochloride not only has a good therapeutic effect on recessive mastitis in dairy cows, but also has a good preventive effect.

8. Topical drug therapy

In the initial stage of inflammation, 2% boric acid solution, 1% murmur3% lead acetate solution, 5% murmurm 10% bile alum solution, Browe's solution (2 parts of lead acetate, 1 part of alum, 40 parts of water) were cold compress in the affected area.

9. Fresh milk therapy

Pour fresh milk 100-200ml into the breast of the disease area, squeeze it out after 1-2 hours, and repeat it again, twice a day. This method can be used for clinical mastitis that is not very serious.

Prevention of mastitis in Dairy cows

1. Regularly monitor the breast health status of dairy cows.

It is necessary to know the breast health status of the herd in time, and take corresponding prevention and control measures for the cows with high PH value, excessive chloride content and high somatic cell number.

2. Strengthen the feeding and management of dairy cows.

The feed should not be too simple, the collocation should be reasonable, and the drinking water must be clean. Where there are conditions, cows should exercise no less than 4 hours a day to enhance their physique.

3. Keep the environment of the dairy house and the body surface of the cow clean.

The barn should be in line with veterinary hygiene standards, have good ventilation facilities, disinfect regularly, and clean the enclosure regularly to prevent the accumulation of feces and urine and reduce the stench such as ammonia. The surface of cattle should be regularly brushed and cleaned to minimize pathogenic microorganisms in the environment so as to reduce the risk of mastitis infection.

4. Ensure milking hygiene and adhere to nipple medicine bath

Wash nipples and breasts with 0.1% potassium permanganate solution before milking and stick to breast massage as much as possible. Reduce the phenomenon of one towel wiping all cow nipples. The milkman raised the hygiene standard and persisted in carrying out the work after disinfection. In addition, the milking machine is regularly and thoroughly sterilized to ensure normal operation.

5. Strengthen the prevention and treatment of recessive mastitis in dry dairy cows.

During the dry period of dairy cows, the occurrence of recessive mastitis can be prevented by injecting appropriate amount of antibiotics into each milk area after the last milking. At the same time, we should pay close attention to prevent the introduction of pathogens, maintain the "closed" state of dairy cows, and avoid new sources of infection caused by the introduction or entry and exit of dairy cows.

Classification of Dairy Cow mastitis

Dairy cow mastitis can be divided into recessive mastitis and clinical mastitis according to clinical manifestations. Occult mastitis can not see its milk changes with the naked eye, does not show any milk clinical symptoms, but with bacteriological and biochemical examination has undergone significant changes. The somatic cell count in milk is between 20 and 500000 / ml. The incidence of this kind of mastitis is much higher than that of clinical type, and the harm is the greatest. The abnormal symptoms of clinical mastitis can be seen with the naked eye. Breast stroma, parenchyma or both are inflamed, clinically manifested as milk degeneration, milk mixed with clots, blood or pus, breast swelling, hardness, warmth, pain and so on.

According to the different nature of inflammation, it can be divided into serous mastitis, catarrhal mastitis, fibrin mastitis, purulent mastitis, hemorrhagic mastitis, honeycomb mastitis and so on.

Causes of mastitis in Dairy cows

(1) microbial factors: the pathogenic microorganisms causing cow mastitis are mainly a variety of non-specific microorganisms, and the infection degree of various microorganisms varies from region to region, including a variety of bacteria, viruses and mycoplasma. Mastitis caused by immersion of pathogenic microorganisms into the nipple tube is recognized as the main way.

(2) Environmental factors: the main way of transmission of dairy cow mastitis is through contact infection. For example, the barn is dusty, unclean and unsterilized; cow dung accumulates outside the door or in the urination ditch; the cowbed is wet, and the first few milks are randomly milked on the cowbed when milking, without timely washing and disinfection; there is no playground or playground, poor drainage, turbid water accumulation; a towel scrubbing a lot of cattle, or used to scrub the cow dung on the arms, the cowshed is really The vacuum pump regulator is not clean, or the rubber tube on the milker is not changed frequently, or the milker is cleaned without any disinfectant.

(3) milking technology: if the milker is not skilled or improper, the mucosal epithelium of the nipple will be damaged; if the milking time of the machine is too long, the negative pressure is too high or twitching too fast, it will also damage the skin and mucosa of the nipple; dirty hands before milking and unmilked milk create conditions for bacteria to invade the breast.

(4) feeding and management: for high-yield dairy cows, the diet with high energy and high protein can not only protect and increase milk yield, but also increase the load of breast and reduce the resistance of the body. a certain amount of vitamins and minerals can play an important role in anti-infection. Such as supplementation of sodium selenite, VE, VA will reduce the incidence of mastitis.

Detection and diagnosis of Dairy Cow mastitis

The symptoms of clinical mastitis are obvious, and a diagnosis can be made according to the changes of breast milk and breast. Symptoms such as redness, swelling, heat and pain appear in the diseased milk area of clinical mastitis, and manual milking is refused. There are flocs in the milk, milk secretion is not smooth and significantly reduced, severe swelling and pain is obvious, loss of appetite, milk production is greatly reduced or milk production stops, blood and flocculent clots appear in the milk.
