Project Description

This program has been a major focus and has extended beyond the extension program.  Over 20 sales were conducted at 11 locations across Kentucky for calves which had met the CPH-45 health requirements.  Approximately 30,000 feeder calves were marketed in these sales, receiving an average premium of $7.38 per hundredweight over the average sale prices reported by the KDA.

Impact

Using a partial budget to account for the increased value of calves less costs (feed, vet cost, interest, and initial value of calves), the net income realized per head was $50.97.  When this is multiplied by 30,000 head, the net increase is $1,529,100 for Kentucky farmers.  By retaining ownership of these feeder calves for additional time in Kentucky, there is also an increased business for veterinarians, farm supply stores and stockyards.  These numbers only include the sales that Ky Extension is involved with and there are many spin-off sales.
