Under normal circumstances, cow farms will perform dehorning about 20 days after the calf's birth, mainly using electric iron or caustic soda, etc. At this time, the dehorned cow is young, easy to control and less painful. The specific method is as follows:
First, materials and tools
1 saw, 1 blower, 1 portable coal stove, a number of coal, fish and stone, self-made iron, Ho Thai, 5% to 8% of iodine, cotton wool, cow Baoding rope.
Second, the steps
1. Cow Baoding. The cows are securely fastened to the neck clips and the ropes must be securely secured so that they can be handled and prevented from accidental injury by the cows.
2. Go to the corner. Use a power saw to quickly cut 2-3 cm of the root of the horn, and ensure that the incision is smooth.
3. Hemostatic packing. Spray hooves on the horns section to reduce the bleeding on the cut surface. Use a 5% to 8% iodine lump to tighten the sinus ostium on the cut surface of the horn. Disinfect the wound and keep the corners of the cows closed.
4. Closed section. The burning red iron is used to burn the wound, soften the cuticle, make the wound closed twice, and play the role of hemostasis and wound sterilization.
5. Disinfection. The fishbone is used to smear the wound surface for sterilization while preventing bacterial growth and intrusion.
Third, pay attention to matters
The dehorning time is best arranged during the day with good light to facilitate the operation. The best choice for cattle is to use cotton ropes to prevent the ropes from loosening during operation, causing operational difficulties and accidental injury to cattle. The cow's standing ground is as rough as possible when skimming, preventing the cow from sliding to a fall when struggling. When the chainsaw is operated, hands should be used to prevent damage to other parts of the cow. The use of soldering iron personnel must be equipped with thick gloves, self-made soldering iron to extend the iron handle as much as possible to prevent personnel arm burns.
