Dairy managers today are faced with the decision to either raise their own replacements on the dairy farm or send heifers to a custom heifer grower. The largest potential challenge of contracting out the heifer raising enterprise revolves around the potential for a moral hazard problem because of hidden action on the part of the custom heifer grower. A principal-agent framework was used to elicit contract terms which provide incentives for the custom heifer grower to perform accelerated growth without heifers becoming over-conditioned. In order to provide incentives to custom growers, heifers returned to the dairy farm should be compared in performance to other heifers of similar age. We solve for the price paid per pound of gain, price paid for inch of wither height above the average heifer on the operation, deduction per unit of body condition score over or under ideal body condition score, and percent of the value of milk production above the average milk production by herd peers. Such comparisons are similar to tournament contracts, such as those used in raising poultry or swine.
