Our producer’s are willing to adapt. They can and they will create change
Sometimes we go too far!
Today cattle have tremendous capacity for post-weaning growth and carcass weight

Hay production/use per cow is increasing at the rate of 66 lb per year
When cattle producer’s are provided effective science-based tools, THEY USE THEM
Dramatic improvement in post-weaning performance, total beef produced per cow, and carcass quality
In the meantime, tools for cow herd efficiency and particularly for fertility have made little to no progress
Our current level of beef production can be sustained with ▪ 20% lower feed inputs
▪ 30% lower methane production
▪ 17% lower N, P and K output Selection for feed intake and residual feed
efficiency is now a reality▪ EPD’s for feed intake and residual feed efficiency
now available for Angus, Hereford, and Simmental

What happens to cow maintenance costs with aggressive selection for
growth, gradual increases in cow size(primarily from increased visceral
organ mass), and genetic potential for milk?

Genetics tools will finally be available to make meaningful improvement in fertility
▪ Genomic discoveries developing now
▪ Hereford, Red Angus, Angus and Charolais working hard to roll out new fertility EPD’s this fall

The Sustained Cow
Fertility (SCF) results,
reported in percentage
units, are oriented such
that larger breeding
values reflect sires
whose daughters calve
annually for more years.
Both bulls have 200 plus
daughters in production
One bull SCF = 170
One bull SCF = 57
In the U.S., we have excellent/enough▪ Growth
▪ Milk
▪ Mature cow size
▪ Carcass weight
▪ Marbling The new frontiers are
▪ Reducing cow/calf phase cost
▪ Cow annual feed energy consumption…true cow efficiency
▪ Progress in fertility of the U.S. cow herd begins this fall
You can’t manage (or select for) what you do not measure
▪ Cow costs
▪ Feed consumption/efficiency (cow phase and post-weaning)
Organize to initiate feed efficiency selection Organize / explore fertility EBV’s Importance of all of these will be magnified in
“post” or “reduced” subsidy era
