چکیده انگلیسی
Commercial custom heifer growing is an emerging industry in the U.S. With the industry growth comes an interest in pasture-based systems for raising dairy heifers as an alternative to traditional feedlots. Questions about animal performance and costs associated with converting cropland to pastures must be addressed. A 3-yr replicated trial on a commercial, custom dairy growing operation compared animal performance and economics of feedlot vs pasture-based systems for raising dairy heifers. The ADG on the pasture system ranged from 0.90 to 0.93Â kg per head compared with 0.91 to 0.95Â kg per head in the feedlot. The pasture-based system had fewer costs, averaging $0.99/d per head compared with $1.28/d per head over the 3Â yr. Productive cropland converted from a corn-soybean-alfalfa hay rotation to pasture was used to graze dairy heifers. Returns from dairy heifers exceeded returns for corn and soybeans in each of the 3Â yr and exceeded alfalfa hay returns in 2 of the 3Â yr. Heifers returned an average of $268/ha over the 3Â yr. The next greatest crop return was alfalfa hay at $225/ha. Heifer returns were greater than corn and soybeans in each year, even when government payments were included.
