It turns out that happy cows produce better milk. The finding is not new. The California Milk Advisory Board has been saying it for years. But now a team of researchers, working with the University of Wisconsin’s Dairyland Initiative, is helping farmers have happier herds. The researchers are visiting dairy farms and showing farmers how to improve their cows’ living conditions. Their advice and information is available around the world on their website. One important area for discussion is how to prevent leg pain, a condition also called lameness.
