The Jorgensen Family Foundation
• Created in 1997 to conduct beef and forage research for the benefit of farmers in the Mid Atlantic region.
• Hedgeapple Farm is the centerpiece of the foundation and serves as a working model operation.
• Hedgeapple Farm focuses on grass fed beef production and direct marketing.

Beef Cow “Efficiency”
The optimum use of your specific set of resources toward a profitable and sustainable level of production.

Beef Cow “Efficiency”
Total pounds of weaned calf per pound of female exposed?
Total pounds of calf weaned per pound of feed consumed?

Issues to Consider
• Mature Cow Size• Milk Production• Reproductive
Performance• Carcass Traits

It All Comes Down to Energy
Can you provide sufficient calories, in a cost-effective manner, to support the machine you have selected and bred?
In a grass-based system the question becomes, do you have a year-round pasture/forage supply of sufficient quantity and quality to support the genetic potential of your cow herd and their offspring?

Priority of energy use by the cow
1. Basal metabolism
2. Grazing and other physical activities
3. Growth
4. Supporting basic energy reserves
5. Maintaining an existing pregnancy
6. Milk production
7. Adding to energy reserves
8. Estrous cycling and initiating pregnancy
9. Storing excess energy

Cattle Operation
Grass Finishing Program
• Approximately 150 head per year
• Steers and Heifers
• Additional calves purchased at weaning from cooperator herds– Use HAF bulls– Follow HAF production protocol

Grass Finishing Production
Growth
• Phase 1 - Birth to Wean (8 months)– 2.0 lbs/day
• Phase 2 - Wean to Yearling– 1.8 to 2.2 lbs/day
• Phase 3 - Yearling to Slaughter (X=19M)
– 1.5 to 2.0 lbs/day

Grass Finishing Production
Carcass Performance Averages (2008-2009)
• Slaughter Weight– 1070 lbs. (Range of 900 to 1200 lbs.)
• Slaughter Age– 19 months (Range of 17 to 23 months)
• Yield Grade– 2.2
• Ribeye Size– 10.9 (typically 1 sq. in. of Ribeye per 100 lbs of live wt,)
• Quality Grade– Steers: 71% Choice; 26% Select+– Heifers: 88% Choice; 12% Select+
