Prevention and treatment of common obstetrical diseases in farmed foxes

1. Miscarriage

Early pregnancy abortion no obvious symptoms, late pregnancy loss of appetite, depressed spirit, often lick the vulva, some discharge hypoplastic fetus, some only a small amount of filthy or red lumps, some were absorbed by the fox itself.

Treatment: patients with symptoms of ①, intramuscular injection of vitamin B2, intramuscular injection of 1% progesterone, 0.3-0.5 ml each time, 2 consecutive injections, or 0.5 ml of 1% progesterone, vitamin E1 ml, intramuscular injection, once a day for 2 days. To prevent complications, ② can use penicillin 400000 units or 20% sulfadiazine 1 ml, or streptomycin injection, 20-500000 units each time. Intramuscular injection, twice a day for 3 days. ③ with stillbirth can be injected with 1ml oxytocin to promote the excretion of stillborn fetus.

2. Dystocia

Treatment: once the occurrence can be timely intramuscular injection of vasopressin 0.51ml, after 30 minutes can not be successfully produced, can be repeated injection, after 24 hours can not be produced, artificial midwifery or caesarean section can be carried out. During artificial midwifery, 0.1% potassium permanganate solution was used to clean and disinfect the vulva, then glycerin or soybean oil was used as vaginal lubricant, long mouth sparse teeth hemostatic tweezers were used to pull the fetus out with the assistance of fingers.

In order to prevent dystocia, the nutrition of feed during pregnancy should be moderate, good reproductive condition should be maintained, and the animal farm should be quiet and not frighten the mother.

3. Mastitis.

Treatment: ① penicillin 300000 units, intramuscular injection. Twice a day for 3 to 5 days. ② closed injection of 0.25% procaine 5 ml mixed with penicillin 300000 units, then multiple injection around the breast until cured. When local suppuration of ③ occurs, wash with 0.1% rivonol and inject penicillin 40-800000 units intramuscularly. In severe cases, incision and discharge of pus. ④ strengthens the care of foxes that give birth to babies. When mastitis occurs, massage or warm compress can be applied at the initial stage to discharge accumulated milk. Trauma around the breast should be detected in time, timely treatment, and strict prevention of infection.

4. Milk deficiency

Treatment: ① thyroxine 10 μ g intramuscular injection. Once a day for 2 or 3 days. ② prolactin 1 tablet, twice a day for 3 days. ③ was injected intramuscularly with 3 ml vasopressin.

5. Endometritis

Treatment: ① intramuscular injection of penicillin 40 ~ 800000 units, twice a day. ② norfloxacin per kilogram of body weight 1ml to 1.5ml or ciprofloxacin lactate 5ml each. ③ cleans vagina or uterus with 0.1% potassium permanganate solution or 0.3% rivanol solution, or uses Jie'er Yin to clean and disinfect vagina or uterus, ④ disinfects cage with blowtorch flame before breeding, scrubbing male prepuce and female vulva with 0.1% potassium permanganate or 0.3% rivanol solution can prevent the occurrence of the disease.

At ordinary times, it is necessary to strengthen the hygienic management of the fox farm and disinfect the cage with blowtorch flame before breeding; for the prepuce of male foxes and the vulva of female foxes, it is best to scrub with 0.1% potassium permanganate or 0.3% Rivano solution before breeding to eliminate the source of infection.

6. Pregnancy reaction

Prevention and treatment: ① in order to restore the fox's appetite as soon as possible, you can adjust the feed breed, that is, the pregnant mother can eat whatever she wants, and feed it with hairy chicken, hairy eggs, eggs, milk, beef, liver and so on, so that it can eat some food every day and maintain the uncomfortable reaction that has been tolerated these days. ② is treated with stomach-strengthening drugs, 1 tablet each time, twice a day, and intramuscular injection of compound vitamin B, 2 milliliters each time, twice a day.

7. Vaginal Gardnerellosis

Prevention and treatment: 20 days before ① breeding, florfenicol injection solution can be injected intramuscularly, 6-15 mg / kg body weight, once a day for 7 days, or 10% florfenicol powder, 100g per ton and 150g doxycycline for 14 consecutive days. At the same time, Gardnerellosis inactivated vaccine was injected into each muscle with 1 ml. In order to prevent cross-infection during mating, ampicillin was injected into the left neck muscle of 1 gram and gentamicin 40,000 units was injected into the right neck muscle. It can effectively prevent empty pregnancy and abortion caused by vaginal Gardnerella infection. ② at present, Gardnerella vaginalis aluminum glue inactivated vaccine has been used in fox farms in China. The immune effect of the vaccine is reliable, the protection rate is 92%, and the immune period is 6 months. It is best to carry out whole-group quarantine in the early stage of the first use of the vaccine, vaccinate the detected healthy foxes immediately, and remove the skin of the detected diseased foxes, or vaccinate the infected foxes 1.5 months after drug treatment. ③ should not touch the aborted fetus, and thoroughly disinfect the cage and floor contaminated by the filth from the vagina of the aborted fox with blowtorch or lime.

8. Parvovirus disease

Prevention and treatment: ① for early onset of fox timely treatment, intramuscular injection of dog immunoglobulin injection, young fox 1 / day, big fox 2 / day, continuous injection for 2-3 days, can be combined with antibacterial anti-inflammatory, hemostasis, antiemetic and other drugs. Gentamicin 20,000 international units / kg, dexamethasone 0.5 mg / kg, mixed intramuscular injection, twice a day; vitamin K30.3 mg / kg or hemostatin injection 0.5 ml / kg, intramuscular injection. ② when the abdominal blood stool emptying began to drink, no longer vomiting, Shuanghuanglian oral liquid can be used 10 to 20 milliliters, one-time deep enema, the effect is better. ③ uses isotonic glucose saline to add 5% sodium bicarbonate injection intravenous infusion, according to the degree of dehydration to determine the amount and times of liquid replacement, appropriate selection of antibiotics, vitamins and so on. ④ should strengthen feeding management and improve hygiene. Regularly disinfect fox houses, venues and utensils with 2% caustic soda water or 10% 20% bleach.
