I think if you don’t count the culling of baby calves the average age is ~6years so like 82kg of plastic.

Thanks for your feedback, I was guesstimating off the top of my head. On doing some research, I see meat cows are usually slaughtered at 18 months - 2 years old in the Netherlands.
5-6 years is the number I see for dairy cows.
