Interpretive Summary: Technical Abstract: Pasture has long been used for dry cows, both as a form of exercise as well as a low cost forage source. Few controlled studies, particularly in the United States, have been conducted with dry cows on pasture. Although high quality pasture can fulfill the nutrient requirements of early dry cows (at least 4 weeks until calving), pasture alone typically does not provide sufficient energy for the close-up cows (within 3 weeks of calving) It is common to supplement pasture with a concentrate source to help prevent ketosis problems, maintain body condition, support fetal growth, and provide the cow with sufficient energy to prepare for the upcoming demands of lactation. Pasture-raising heifers can be a cost-effective method of raising heifers when either raising your own replacements, or acting as a contract heifer-raiser. These animals must be managed similarly to other groups of animals- pastures must be rotated, supplements must be provided, and they must be observed on a regular basis. Pasture, plus some good management, can provide a low-cost labor-efficient system for raising heifers or managing dry cows if these animals are properly managed during these critical phases of the growth and lactation cycles. |
