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.
Nigel Cook is with the Dairyland Initiative.
"Lameness impacts everything a cow gets to do in her day. It impacts the way she rests, the way she milks, the way she eats, her ability to reproduce and ultimately her ability to stay on the farm.”
Speaking in a cow barn, Cook explains that a bed of sand can provide a good place for cows to lie down during the day.
The deep, soft bedding of sand creates an environment where cows can rest half the day, and that is incredibly important to cows.
The researchers advise farmers to provide bigger stalls, the areas where cows are kept in a barn. They also say farmers should use more fans to keep the animals cool, and feed all their cows at the same time.
And researchers say it is a good idea to keep cows with their usual group of friends when it comes time for them to give birth. This helps lessen the stress for the cows.
Mitch Breunig owns the Mystic Valley Dairy in the U.S. state of Wisconsin. He says he used the advice to improve the conditions for his 400 cows.
"If you take away their stress, they actually produce more milk. And then the other thing that actually is interesting is they do it by eating less feed."
Since he made the changes, Breunig says the dairy’s production has increased. His cows have gone from producing 49 liters of milk a day to almost 57 liters.
Also, his cows have fewer injuries and live about a year longer than before. That is good for the animals, and for people, too.

这一发现并非首次。多年来，美国加州乳品协会一直持有这个观点 。但现在有一组研究人员正与威斯康星大学合作进行“乳牛场计划”，帮助农民们改善牧群的心情 。
研究人员建议农民们把牛棚弄得更大些，因为这里是牛待着的地方。研究人员还说，农民们应该配置更多的风扇，让奶牛凉快些 。此外，喂食要同时进行 。
米奇 布鲁尼格是威斯康星州神秘河谷奶牛场的场主。他表示，自己用这些建议来改善了400头奶牛的生活水准 。
