Always wear gloves.

Pierce the top of bottles before loading them on repro guns. Otherwise you run the risk of pushing the bung into the bottle when attaching it.
Apply the bottles like this.

Always use 18g by 1.5 inch needles on the end of the slap shot.
Change needles regularly ( or if they get dirty). Every row in a herring bone.

My preferred injection is the top of the thigh as this is all muscle.
Jab the needle into the cow like this.
Inject the gun and let it refill before removing the needle ( this helps with avoiding product dribbling out ). Tilt the gun slightly so when it refills you can check there is no air in the barrel.
It is critical that there is no air in the barrel and NO product drips back out of the cow. Give extra if this happens please.
