Newcastle University found that farmers who named their cows gained a higher yield of milk.
Dr Catherine Douglas: “Placing more importance on knowing the individual animals and calling them by name can, at no extra cost to the farmer, also significantly increase milk production.”
A happier cow delivers more milk, and that’s about $300 a year, retail.
But filing birth certificates isn’t enough. Dairy farmer Dennis Gibb says that treating every cow as an individual was “vitally important”.
