Dr. Gary Rogers, UT Dairy Extension

ENR$ is the expected net revenue from one unit of semen for a sire relative to a service from an average non-A.I. bull. ENR$ considers the cost of the semen as well as estimated relative conception rates ERCR, revenue and costs (feed, health, culling, etc.) associated with daughters and future generations of descendants. ENR$ is affected by a producer's herd management level and milk market type. . . . . keep scrolling down, click on your choices, click on brightly colored words for further detail (in glossary)!

		Pricing based on fluid market with only fat premium - sorted by USDA Fluid Merit
		Pricing based on cheese market - sorted by ENR$
		Pricing based on cheese market - sorted by USDA Cheese Merit

Step 3 -- Select "best-fit" Herd Management level

		Above average -- (Excellent reproductive management, especially high conception rates, and excellent heifer management)
		Average -- (Average reproductive and heifer management)
		Below average -- (Below average reproductive management, especially low conception rates, and below average heifer management)

Step 4 -- Choose ALL or a LIMITED NUMBER of bulls

		ALL bulls with August 2008 ENR$
	OR
		Choose a minimum ENR$
		Choose a minimum USDA Net Merit
