For dairy farmers, the biggest problem is that the animals are sick, and for cows, the same is true. Those who are seriously ill may directly lead to death, and the light may also affect the feeding, estrus, and reproduction of cows. Next, I will introduce some diseases of dairy cows that are not easy to recover and the treatment methods for them.
1. Cows can't lie on the ground
Cows' lying-in is a serious symptom. Most of the dairy cattle will eventually be eliminated or died, and a lot of manpower, material resources and medicines will be needed during the treatment period.
Check the sick cow:
In the process of examination, it is necessary to check the lying posture of the cow, check whether there is lateral lying. If there is lateral lying, we should find ways to correct the lying posture of the sick cow. Otherwise, it will cause rumen gas, foreign body pneumonia caused by swallowing rumen fluid into the trachea, chest pressure caused by compression of the diaphragm is too high and dyspnea, etc.
Calcium preparations are also very dangerous when lying on the side, often leading to cardiac arrest and death. Also, check the mental status of cows. If cows suffer from mental atrophy, silence, drooping head and ears, eyelids half-closed, tachycardia, and weakness? If these symptoms occur, attention should be paid to distinguish them from hypocalcemia, which often indicates that cows suffer from acute septic uteritis or acute toxic mastitis. Finally, check whether the cows are trying to stand up again.
If the cow stands consciously, the cattle breeders should move the sick cow to the non-smooth ground to avoid too smooth ground to make the cow fall again after standing. Besides, cattle farmers should help dairy cows stand to some extent when they observe that the cows attempt to stand. They can use hip nodule rings to assist dairy cows to stand, or they can use inflatable airbags to prevent dairy cows from standing under their legs.
Unlike simple muscle, nerve injury, hypomagnesia, hypokalemia and hypophosphatemia, the cow's "lie-down" syndrome is not inherent. The cow's "lie-down" syndrome is very inconsistent. The main symptoms are unable to fall to the ground, normal or decreased appetite, normal or slightly high body temperature, normal or increased heart rate, sometimes heart rate is not visible. Qi, most cattle frequently try to stand, and hind limbs can not stand completely, can only crawl, some cattle appear dog-sitting posture. Serious sick cattle are in a lateral position, which is characterized by twitching of limbs, the tension of horn arch, excessive sensitivity and loss of appetite. Complications such as mastitis and bedsores often occur because of long-term lying down.
The course of the disease:
The duration of the disease is not consistent, mainly based on the location of the lesion, the nature of the disease and nursing conditions. If the diagnosis and treatment are correct, 50% of the sick cattle stand within 3 days, and if they can not stand within 7 days, the prognosis is poor.
When all kinds of injuries including muscle and ligament injuries have been diagnosed, they should be eliminated early to reduce economic losses. Calcium preparation, magnesium preparation, phosphorus preparation, and potassium preparation can be used for symptomatic treatment of cattle that are expected to recover. If 20% calcium Boroglucosate 500ml - 800ml once the intravenous injection, twice a day. 20% sodium dihydrogen phosphate 300 ml intravenous injection or 5% potassium chloride 100 ml glucose 500 ml slow intravenous injection, and always pay attention to the heart condition. Subcutaneous injection of 25% magnesium sulfate 100ml-200ml. These drugs can be used repeatedly under the condition of ensuring blood calcium concentration.
Vb, VB12 or strychnine can be injected into lumbar stubble nerve acupoints for cattle with nerve injury. Complicated muscle injury can be treated with Shujin Huoxue Tongluo medicine. Preventing muscle atrophy can be massaged locally and then applied with "compound camphor liniment" and other skin irritants. Careful care must be taken while the medication is administered, which is very important for the recovery of cattle. When "lying down" cattle occur, first put the diseased cattle on dry, clean and soft land, do not drive them forcibly, turn over several times a day to prevent bedsores. When the cattle try to stand, they should be assisted by a human.
Strengthen feeding management during dry milk period and transfer to parturition room for separate feeding in late pregnancy. In prenatal low calcium feeding, pregnant female cows were intramuscularly injected with vd310 million international units within 6-10 days before delivery, once a day until delivery, intravenously injected with 20% calcium gluconate 500 ml and 20% glucose 500 ml, once a day, continuously injected for 2-3 days. During midwifery, careful not to pull excessively to reduce tissue damage.
In the feeding process of dairy cows, improper feed mixing may lead to uterus shedding after delivery, or because of excessive obesity of dairy cows leading to uterus contraction and inability to shear.
After uterine prolapse, if uterine bleeding occurs, vitamin K3 and hemostatic agents should be injected, and large blood vessels should be ligated at the same time. Then, the fully or partially detached uterus was washed with 0.1% potassium permanganate solution or 0.1% salt solution, and the uterus was held by the assistant's hands. The uterus wall near the vagina was pressed by the operator's palm or fist and sent in bit by bit.
In the course of pushing, if you encounter Niu Nu-chi, the returned part will be pressed tightly to prevent it from coming out again. When the uterus is all fed into the pelvic cavity, the surgeon lets the assistant press and fix it tightly outside the cow's vagina to prevent it from coming out again. The surgeon washed his hands, applied lubricant to his right hand and slowly put the uterus through the cervical orifice into the abdominal cavity for reduction.
To prevent incomplete reduction and uterine inflammation, 4 million international units of penicillin can be dissolved with 500-1000 ml saline and then poured into the uterus. The uterus can be restored to its best state by using the pressure of water. Meanwhile, the intramuscular injection of Postpartum Kang (mainly ofloxacin and pefloxacin mesylate) was 20-40 ml and ergot maleate injection was 4-6 ml.
After the reduction of the uterus, fluid, cardiotonic agents and anti-inflammatory drugs should be supplemented according to the mental status of cattle to adjust the physiological function of cattle and prevent secondary infection. Some cattle will have a stress reaction, such as reduced lactation, drinking water, loss of appetite and so on, which can be treated by appropriate measures.
