I have seen goats disbudded with the hot iron for years & always dreaded the procedure. It is over quick - but very painfull. I had read reviews from people who used this paste & said it was less painful than the dehorning iron so i decided to try it on my Nigerian buckling. Maybe I put it on a little too thick, but he started screaming & panting after 5 minutes so I removed it & used vinegar to stop the burning. It might be better than the iron if you only had to leave it on for 5 minutes or less - but he was in way too much pain to leave it on as recommended. I took him to the vet a few days later & had him disbudded with an iron under anesthesia - best method ever! He took a nap & woke up with no horns, no pain, no stress - for him or me!. I don't think he had any idea he had been dehorned.
This product works well if used exactly as directed. It is best to use on very young calves and prevent them from scratching at the site for a few hours. It is best to clip the area where you will apply it, put a ring of vaseline around the horn site and use a sparing amount of dehorning paste. Can be less traumatic on calves if done right.
When we were new to goats we bought one from a lady and she said she could dehorn him for us before we left. We said sure and she pulled this product out. You have to leave it on for one hour and it tends to run everywhere. Make sure you have vinegar on standby to wash it off and a lot of water. I felt so bad for our little boy we pulled over and washed it off. Unfortunately his little head now has a funky spot where the hair didn't grow back. Especially do not use if you want this animal to be a show animal. Save your money and buy a burner.
