How to prevent postpartum uterine prolapse in dairy cows?

Posted on: December 5, 2019, edit by Eleanor

Uterine prolapse: refers to the partial or total reversal of the uterus out of the vagina. It is a common disease of postpartum dairy cows. It is often called "blow gourd" by the common people in many rural areas. The disease is a more difficult disease to treat in the clinic, and it is easy to recur after treatment and usually can not be cured for a long time. Many high-yielding dairy cows are eliminated as a result, which brings great harm to the majority of dairy farmers. The following is a detailed understanding: the causes of postpartum uterine prolapse in dairy cows prevention and treatment of postpartum uterine prolapse.

Causes and prevention of postpartum uterine prolapse in dairy cows
Causes and prevention of postpartum uterine prolapse in dairy cows

1. Causes

Nutritional facts.
Due to the inappropriate or lack of phosphorus and calcium phosphorus in the diet of dairy female cows, the uterus of dairy cows falls off after delivery, or the uterus of some dairy cows shrinks weakly due to the excessive obesity of dairy cows, resulting in the excessive anger and blame of dairy cows after delivery, resulting in uterus shedding.

The slope of the stadium is too steep.
For the convenience of drainage in summer, the gradient of some dairy farms is more than 10 degrees. During the period of lying in the nest, the vagina is below the gradient, and the uterus moves backward for a long time, resulting in uterus detachment after delivery. The gradient of the dairy farm is 3-5 degrees.

Feeding management.
Imported Australian cattle have a strong postpartum stress response due to their wild nature. To prevent workers from injuring cow babies, the uterus did not recover and then moved too early, leading to uterus prolapse after delivery.

2. Preventive measure

Rational ratios of calcium and phosphorus are allocated to ensure that the feed formulation is different in each period. The dry milk period is more than 60 days, to ensure that the dairy cattle have enough finishing period, and to strengthen the feeding management during the dry milk period.

Strengthen exercise before calving. Every day, exercise should be about 2 kilometers. Dairy pedometers can be installed in conditional cattle farms. The artificial daily drive can also be carried out.

The gradient of the dairy stadium should be 3-5 degrees. The stadium should be paved with vertical yellow bricks, averaging 110 pieces per square meter. The gradient should not be too large.

3. Treatment

Anesthesia: Nerve block conduction anesthesia is used. Deep anesthesia is carried out between the 1st and 2nd segments of the tail vertebra. There is a concave point at the lateral joint of the tail raised by hand, that is, the central point, which is the injection point of anesthesia.

Shearing and disinfection: Use curved scissors to cut hair at the central point, try to be as clean as possible, then use 5% iodine tincture to disinfect, smear from the middle to all sides, try not to repeat smear, prevent and cure the infection caused by incomplete disinfection.

Injection anesthetics: 2% procaine 10-15 ml, 45-65 degree with a syringe, oblique forward puncture, penetration depth of 2-4 cm, penetration through the intervertebral arch ligament, there is a sense of penetration of paper, no resistance at injection is correct, 5-15 minutes to start anesthesia, anesthesia time is generally 60-90 minutes.

Clean the uterus. The uterus was cleaned with warm water at about 35 C, the placenta was removed, the finger belly was peeled off, and the uterus was gently handled as far as possible. Then the uterus was cleaned with a 1% potassium permanganate solution at about 35 C for 2 to 3 times.

Uterine reduction. Veterinary surgeons force their hands along the cervical mouth to deliver to the cow's vagina. The assistant pulls the uterus aside to prevent contamination and delivers the uterus to the uterus until it is about the length of an adult's arm. After uterine reduction, 5 to 8 liters of potassium permanganate solution was injected into the uterus for further uterine reduction.

Traction fixation. Prepare a 6-meter-long hemp rope and a large O-ring. Fix the rope on both sides of the O-ring and fasten it to the vagina. The other end of the rope is tied to the cow's neck. If necessary, sew 3-5 stitches on the vagina by spiral suture to prevent the excessive uterus from coming out again.

Medication. Ceftiofur sodium was dissolved in 10% saline by intravenous drip with 180 units of Cephalosporin Pioneer (the main ingredient is Ceftiofur Sodium) for 7 consecutive days. Vitamin K50ml was injected intramuscularly for 3 consecutive days. At the same time, the energy-supplementing mixture was injected intravenously for 7 consecutive days. At the same time, cattle breeders should feed dairy cows 10 liters of postpartum soup, namely 500 grams of brown sugar, 1-1.5 kg of bran, 10 kg of warm water, one-time drinking.

4. Conclusion

A postpartum uterine detachment of dairy cows is caused by many factors, mainly by inadequate feeding management and exercise, which has a certain relationship with our usual observation. The study of cow uterine detachment is mainly the method of uterine reposition and the method of fixing rope, to have targeted treatment.
