Mature Cow Weights

How has the selection for heavier weaning and yearling weights influenced the mature size of the nation’s cow herd?

Questions: Magnitude of change? Implications of change?

How big is Today’s Cowherd?

Common logic “Mature cow weight = weight of finished offspring”

Meat Animal Research Center Germplasm evaluation program 37,000+ cows Mature Cow Weight correlated with hot carcass weight of

progeny (0.81) Progeny hot carcass weight = 0.599 * (mature cow weight)

Calf Weight, lbs

1400 lb cow has to wean at least 50 lbs more calf !

Is there optimum ?

Tough question period…..

Factors: Environment • Available forage resources

Reproduction Marketing strategy• Sell at weaning/ retain ownership

Bottom Line

1990-2009

Fed cattle Harvested at larger weights Gain weight 15% faster Require 0.42 less lbs feed/lb gain

Increased commercial beef production per cow by 17.5%

Consequence

Mature weight of the nation’s cowherd has increased

1990 = 1203 lbs (1179-1228 lbs)

2009 = 1368 lbs (1346-1390 lbs)

Have we changed?
