Livestock Update, August 2001
John Hall, Extension Animal Scientist, Beef, VA Tech
Some refinements to the Virginia Premium Assured Heifer requirements were by the VPA Heifer Committee late this spring. These changes will apply to VPA Heifers starting September 1, 2001. Producers of VPA Heifers need not be overly concerned, as the changes are minor. Here is an overview of the changes:
Complete requirements follow.
Stated birth date with projected age at calving being:
22 to 26 months of age (Spring calving heifers)
22-30 months of age (Fall calving heifers).
Stated birth date with age at sale between 11 and 17 months of age.
Frame size - All heifers must be frame score 4.5-6.5.
Structure - All heifers must be deemed structurally correct by the local VA Premium Assured Heifer Committee which includes the local Animal Science Extension Agent.
Muscling - All heifers must possess adequate muscling without being extreme. USDA muscling score 2-50 to 1.0 (upper half of 2 muscling and better).
Body condition score - All heifers must be BCS 5 to 7 (1=emaciated; 9=obese).
Breeds - Any breed or breed combinations are eligible, but breeds must be specified.
Service sires - Bred Heifers
Open Heifers - All open heifers must have a reproductive exam by an approved professional. Heifers may not have received any growth implants.
Pelvic area - All heifers must have a yearling pelvic area of 150 cm2 or greater at prebreeding (presale) examination. Heifers with pelvic areas <150 cm2 may not be sold. Pelvic areas need to be reported but will not be listed in the sale catalogue.
Reproductive tract score - All open heifers for sale that are 12 months old or older must have a RTS of 3 or better. (Colorado Sate reproductive tract scoring system).
Open guarantee - All heifers will be guaranteed open on sale day (except heifers sold as exposed). If a heifer sold as open is proven pregnant by a veterinarian within 30 days of the sale, the consignor will replace the heifer or refund the sale price of the heifer and take possession of the heifer.
Conceived within restricted time period - All heifers must have conceived within the first 50 days following initial artificial inseminations and/or natural mating.
Pelvic area - All heifers must have a yearling pelvic area of 150 cm2 or greater at prebreeding examination or a pelvic area of 180 cm2 or greater at pregnancy examination. Heifers not meeting this requirement may not be sold as VA PAH. Pelvic areas need to be reported but will not be listed in the sale catalogue.
Pregnant guarantee - All heifers will be guaranteed pregnant on sale day. If a heifer sold as pregnant is proven open by a veterinarian within 30 days of the sale, the consignor will replace the heifer or refund the sale price of the heifer and take possession of the heifer.
