HETEROSIS Economic and production benefits associated with
PAYS heterosis are documented by decades of industrywide
research in commercial crossbreeding systems.
DIRECT HETEROSIS
Increased performance of the crossbred calf relative to the average of
the straightbred parental breeds.
+ 1.9% Survival to weaning REPLACEMENT
+ 3.9% Weaning weight
+ 2.6% Post weaning gain
+ 3.8% Yearling weight
+ 2.2% Feed conversion
MATERNAL HETEROSIS
Increased performance of the crossbred cow relative to the average of
straightbred females of the parental breeds.
+ 3.7% Calving rate
+ 3.8% Weaning weight
+ 38.0% Longevity
+ 17.0% Number of calves
+ 25.3% Cumulative weaning weight

1 On average, Oklahoma State University researchers measured about 2 pounds per day less moderate-quality forage (Oklahoma pasture) intake in the black
baldy cows. On an annual basis the black baldy cows would be expected to consume about 725 pounds less forage.
