Injection method Intramuscular injection: Injection site: Bovine neck and buttocks, muscular parts. The injection site of the neck is on the dorsal side of the middle 1/3 and the lower 1/3. The injection site of the buttock is on the gluteal muscles on both sides of the sacral vertebra and the tail root after the waist, but not on both sides of the thigh. Injection method: Puncture the needle into the muscle vertically to the skin. The depth is usually 2-3 cm. The buttock muscle is punctured into 4 cm or deeper and then inject the liquid. Subcutaneous injection: Injection site: Dairy cow neck side, skin easy to move parts. Injection method: Lift the skin of cattle in one hand, make it wrinkle, then puncture the needle into the subcutaneous fold. After loosening the skin, the needle can swing under the skin, and then inject the liquid. Intravenous injection: Injection site: The most commonly used injection site is the jugular vein. Jugular vein injection is usually in the middle of the neck 1/3 because the upper 1/3 of the jugular vein has branches, and the lower 1/3 of the jugular vein is deep. Injection method: Press the proximal end of the vein with a left hand, block blood reflux, make vein dilate, then put a needle in the place about 2 centimeters above the pressing point with the right hand, at 45-degree angle with skin along the direction of blood vessel, puncture the skin, then puncture the blood vessel. When there is blood flow out, the needle has been punctured into the blood vessel, and then the needle is punctured. Head along the direction of blood vessels push 1 to 2 centimeters, and then check the return of blood, can slowly inject liquid medicine, inject a large amount of liquid medicine, 30 to 60 milliliters per minute is appropriate. Needles and catheters should be fixed to the skin with small clips to avoid slipping during the injection. Oral method: Preparations: pills, pill Throwers Operation: The cattle farmer installs the pill into the thrower, holds the pill thrower in his right hand, enters the mouth from the side of the mouth of the Spotted cow, holds the root of the tongue, puts the pill thrower into the mouth of the cow and pushes it forward slowly, touches the throat gently when the end reaches the throat, and inserts the thrower into the throat when the cow has swallowing action, and the left hand is in the throat. When the left hand perceives the end of the thrower, it confirms that it has been inserted into the esophagus.

The thrower can be inserted slowly. When the handle of the thrower is close to the lip of the cow, the pill is pushed out, and then the thrower is pulled out slowly. Infusion method:

(1)Operation: 1. After the cattle were fixed, the dairy farmer stood on the side of the cattle. 2. Fix the head and neck of the cattle with the right elbow. Put the thumb and index finger of the right hand into the edge of the mouth of the cattle, and open the mouth of the cattle. 3. Hold the feeder in your left hand, gently extend the end of the feeder into the throat of the cow, and slowly feed the feeder into the esophagus following the swallowing action of the cow. 4. When the feeder catheter passes through the throat, it stops and frees its left hand to touch the neck of the cow. At the same time, it pulls the feeder with the right hand. If the left hand can touch the feeder, it means that the catheter is properly put into the esophagus. Continue to insert the catheter and administer the feeder. 5. After filling, fold the catheter and gently pull out the feeding tube.

(2) Note: If the hard segment of the feeding tube is not enlarged or accompanied by cough when inserting the catheter, the feeding tube should be pulled out in time and re-put. Infusion cattle binding: Prepare: Choose the right length, thick and thin cotton rope Cattle preparation: cattle up to the neck shackles and stand firm Binding: Put a movable cage on one end of the rope and put it on the upper and lower jaws of the sick cattle. The other end of the rope goes around the root of the ear of the cattle and goes through the cage to adjust the looseness of the cage. Then the free end of the retaining rope is fixed on the neck flail.
