Systematic Heifer Development -- The Virginia Premium Assured Way
Livestock Update, August 2000
John Hall, Extension Animal Scientist, Beef,Virginia Tech
The Virginia Premium Assured Heifer (VAPAH) Program is off to a good start. Over 300 heifers were enrolled last year and producers were pleased with the program. At least four sales will feature Virginia Premium Assured Heifers between Fall 2000 and Spring 2001. The VAPAH program is an educational and technical assistance program for producers who raise or market replacement heifers. Remember you don't have to sell your heifers to be part of the program. Producers will receive summarized heifer data as well as technical assistance.
The process for developing heifers using VA Premium Assured methods is not difficult, but it is easier if the process is carried out in stages. The process is the same for fall calving or spring calving heifers. The critical stages and processes are as follows:
Weaning (6 to 10 months of age)
Prebreeding (13 to 14 months of age)
Pregnancy Exam (16 to 18 months of age)
