Get Ready Now for the Calving Season
Getting ready for the calving season begins long before the first calves are born. For producers who will start calving in late February or early March, now is the time to make sure the cows are in good body condition and the calving equipment and supplies are ready for use.

Body Condition Score at Calving is the KEY
One of the major constraints in the improvement of reproductive efficiency of beef cows is the duration of the post-calving anestrus period.

Genetic Correlations Between Postweaning Feed Efficiency and Cow Traits
Australian scientists used postweaning records on 1781 bulls and heifers individually tested for feed efficiency, and cow records taken at 4 yrs. of age on 751 of the same heifers to estimate genetic correlations between postweaning feed efficiency and certain cow traits.

Managing Young Females
Some producers feel that if cows are thin at calving, then "flushing" (feeding a high level of energy) the cow after calving will compensate for poor condition and result in acceptable breed back.

Selecting A.I. Sires for Maximum Profit
The economic concept of net present value (NPV = future value [$] of net genetic gain discounted to present value [$] by adjusting for interest and inflation) was used by Washington State Univ. scientists as a method of selecting A.I. beef sires for maximum profit over a 3-generation time horizon.

Genetic Relationship Between Heifer Pregnancy and Scrotal Circumference
Colorado State Univ. and Brazilian researchers used 43,511 records on Nellore heifers and young bulls to determine the heritabilities of yearling heifer pregnancy and scrotal circumference, and the genetic correlation between the two traits.
