Prevention and treatment of breast redness and swelling in lactating sows

Sow

First, the cause of sow mastitis:

1. The enclosure area is small, the ground is rough, the breast is squeezed and rubbed, and pathogenic microorganisms such as streptococcus, staphylococci, Escherichia coli or Pseudomonas aeruginosa invade, especially nipple injury is more prone to bacterial invasion and lead to mastitis.

2. When sows are constipated, the toxins produced by fecal fermentation will damage organs, cause all kinds of inflammation, such as uterine inflammation, and aggravate sow breast edema, which can cause mastitis.

3. Before and after giving birth, too much concentrate feeding, especially too many carbohydrates, leads to excessive swelling and rupture of the breast, resulting in hemorrhagic mastitis.

4. The barracks are unhygienic, especially before giving birth, without washing sows' breasts, or without disinfection or cleaning, resulting in bacteria breeding and mastitis caused by bacteria infection.

5. Less piglets, more breast milk, endless sucking, accumulation of surplus milk, nipple blockage, poor lactation and so on can lead to mastitis.

Symptoms of sow mastitis

1. Breast symptoms of mastitis:

Redness, swelling, pain, heat and dysfunction. At the initial stage of the disease, the sows' breasts are congested, red, swollen, painful, and refuse to breast. if the piglets come into contact with the breasts, the sows will immediately stand or moan, restless, irritated, and messy, and the hateful sows will attack or even eat the piglets (piglets). The lactation of diseased pigs is reduced or poor, and the artificially extruded milk is thick, coagulated or mixed with purulent blood. The breasts of diseased pigs are abnormally swollen. In the later stage, a large number of connective tissue proliferated, the breasts became hard, and even the nipples were closed.

2. Systemic symptoms of sow mastitis:

After the illness, the sows are depressed and have no appetite. Some of the body temperature rises to 40 ℃ ~ 41 ℃. The longer the time is, the more difficult it is to control and recover. The sick sows lose fat quickly, lose weight, and even become dehydrated.

Third, the harm of sow mastitis:

The main results are as follows: 1. After the sow mastitis is cured, the estrus period is prolonged after weaning, and there is no estrus or no estrus.

2. The quality of milk is very poor, piglets have diarrhea, immune decline, easy to secondary diseases.

3. Piglets lose weight and exhaustion due to lack of milk, and even starve to death or die of dehydration.

Fourth, prevention and control of sow mastitis:

(1) Prevention

1. Strengthen the hygienic management of sow houses, keep them clean and disinfect them regularly. When giving birth, the sow should lie on its side as much as possible, and the midwifery time should be short to prevent suckling piglets from biting nipples.

2. Three stitches of sow health care:

3. 15 ml of Jiling was injected on the day of giving birth, the 3rd day and the 7th day after giving birth.

4. 7 days before and after parturition, each ton of feed is added: 'Meiyishi' 1 kg + Panick 0.5 kg

(2) treatment

① local therapy:

A. After washing and drying the breast, apply it hot with a warm towel, then apply the medicine to the skin of the affected part of the breast with fish fat ointment (or cod liver oil) and camphor ointment.

B. the effect of injecting antibiotics into the nipple is very good, that is, the antibiotics are diluted with a small amount of sterilized distilled water and injected directly into the milk duct. During the medication period, suckling piglets should be artificially breastfed to reduce sow stimulation and protect piglets from milk infection.

② systemic therapy:

A. intramuscular injection: penicillin, streptomycin, gentamicin, enrofloxacin, ciprofloxacin and sulfonamides, intramuscular injection for 3 to 5 days. The therapeutic effect is better when penicillin and streptomycin or penicillin and neomycin are used together.

B. It is recommended that sows be injected intramuscularly with Jiling or Saifukang 15ml.
