I have 1 young hiefer & 3year old 1st time cow that has developed a large knot on the left side of thier neck in the same location.
It looks like what a cattle grub would make before it pops out.
I have medicated both by Ivemectan shots just two months prior & back pour on. I have since caught them & also re- meddicated both. The knots continue to grow but I have not seen a grub escape nor is there a small opening. The knots do not apear to be attathed to muscle. You can grab & squeeze them and move them around they are only skin deep.
What is the incubation period of a cattle grub? and why is the medicine not doing it's job? Or can you suggest a alternative?
