Pig ear notching system
Why is knowing the age of every pig important?
Knowing the age of every pig is THE MOST IMPORTANT piece of information in a commercial piggery.

How to avoid this?
Know that the industry standard weight for a 16 week old pig is 70kg of live weight.
Know the EXACT age of every pig in your piggery - even if you have 1000’s
How to know every pig’s age?
Ear notch piglets with the week of the year they were born in (done together with teething, tailing and iron injection)
Ear notch ALL piglets born (when doing teeth and tailing) will enable you to know exactly how old every pig in your piggery is.
This in turn will enable you to benchmark with industry standards to identify low performance problems so that you can look at how to improve them.
