Studies are showing that dairy heifers raised on pas- ture are healthier, cost less to raise and ultimately give more milk. Jennifer Blazek, a Univer- sity of Wisconsin Dane Coun- ty dairy and livestock educa- tor, began a project last year to encourage more dairies to raise their heifers on pasture. “We have a lot of large farms that raise heifers in con- finement,” she said. Grazing heifers is a cultur- al adjustment for many dairy farmers. “They have invested in facilities for heifers and feel they would be going back- ward to raise them on pasture, because that’s what small farms do,” she said. “The big dairies feel they can do it better and more efficiently in modern facilities.” She first did a survey of every dairy in the watershed. The idea was to reduce phos- phorus and runoff from the barnyards and confinement facilities. The survey sought to see who might be interested in cost-sharing to help cover taking some land out of crop production and putting it into pasture, and to assess percep- tions about grazing heifers. “In September we had a field day and pasture walk on An Investment In Quality Never Stops Paying You Back.

He has been cus- tom-raising heifers on grass for many years,” she said. “It was a great opportunity for people to see how it works, and for other farmers to hear why the owner decided to do this.” He addressed issues they were concerned about. “Some thought the heifers would be more skittish and harder to handle when they come into the milk parlor for the first time,” she said. The heifers were actually much calmer and friendlier. They also had much better muscle tone and calved eas- ier, for their first calf, than heifers raised in confinement, she said. “They had more exercise, were healthier and outper- formed confinement heifers,” Blazek said. The heifers were on pas- ture in the morning and af- ternoon, and at mid-day were brought into a shed and fed a little grain to encourage them to come in for breeding and health checks. “They were handled a lot and were not wild. When we did the pasture walk they all came over to check us out,” she said. One of the farmers who decided to try pasturing heif- ers has a 250-cow dairy and is interested in heifer health. “We want to follow up on these projects to find out how long these heifers last in the herd compared with their confinement-raised counter- parts,” Blazek said. Many dairymen are hes- itant to try it, thinking they don’t have enough land and don’t want to take any crop land out of production. “They don’t realize there is equal feed value in pasture, and less labor. Heifers feed themselves; you only have to move the temporary fence,” she said. “I recently gave a presen- tation with Adam Able, an Turn to PASTURE, Page 5
