3 Categories of Beef Breeds
Maternal
Terminal
Composite

moderately sized and recognized for ability to have healthy calves
Ex. angus, hereford, shorthorn, red angus
What are terminal beef cattle? Give examples
animals that are larger in size and used for meat purposes
Ex. charolais, limousin, simmental

crossbred of different breeds
Ex. SimAngus, Braford, Beefmaster

Angus
Hereford
Limousin
Why are different cows found throughout the US?
Because of…
terrain
feed accessibility
environment
What are the 4 Structures of the Beef Industry
Cow-calf
Seedstock
Stocker Calf
Feedlots
What is the cow-calf segment?
The first stage in the beef production process, where cows are bred and produce calves for sale or further feeding
What is backgrounding?
operation that receives stressed calves and improves their health
takes place after cow-calf and before stocker)
What type of animals does the seedstock segment deal with?
higher end genetic animals
What does the Seedstock segment do?
pedigrees registered with breed association
sells yearling bulls for breeding commercial beef cow herds
What type of animals does the stocker calf segment deal with?
Weaned/growing animals
What is the stocker calf segment?
uses grazed forages to grow weaned calves by 200-300 pounds
What is the feedlot?
Where animals are at the feedlot, adding last compositions of fat
What is so special about feedlots?
They are located in parts where there isn’s any ventilation, roofs, buildings
located in climate where shelter is not needed for winter conditions
In a commercial beef cow business, what takes place during March and April?
many herds calve
In a commercial beef cow business, what takes place during April or May?
Cow-calf pairs begin grazing
In a commercial beef cow business, what takes place after the cow-calf pairs begin grazing?
Bulls are released for 60-90 day breeding season
In a commercial beef cow business, what takes place during Sept, Oct, or Nov
Weaning
In a commercial beef cow business, what takes place during Nov-Dec
Grazing season is completed
In a commercial beef cow business, what takes place during Dec. - March?
feed cows inexpensive to maintain body condition; provide natural or constructed shelter from bad weather
What are some corn co-products?
High-fructose corn syrup
Ethanol production
What is Acidosis?
A metabolic disorder where the metabolism of the animal is overloaded with acid
Lactic acid, acetic acid, propionic acid, butyric acid
What causes acidosis?
An abrupt upshift in intake of fermentable energy
Give some examples of this abrupt upshift
switching from whole corn to ground corn
switching from pasture to corn silage
What are some Acidosis Acute Issues?
Laminitis, founder (sore feet)
Listlessness, diarrhea
What are some Acidosis Chronic/Subacute Issues?
sporadic feed intake
excessive hoof growth; loss of agility
What are some long term effects of Acidosis?
Rumenitis
In the U.S. Dairy herd, what percent of pregnancies are due to AI?
~90% of pregnancies
In the U.S. beef herd, what percent of pregnancies are due to AI?
10%
List some bull semen companies
ABS Global
Alta Genetics
Genex
Select Sires
What is body condition scoring?
looking at amount of composition cows have, ultimately amount of body fat
What is the relationship between BCS and body fat?
As BCS goes up, so does amount of body fat
What are some challenges to beef cattle health?
Calf diarrhea (scours)
Bovine respiratory disease (BRD)
Blackleg
Bloat
What challenge has the largest economic impact to the cattle industry?
Bovine respiratory disease (BRD)
What is blackleg?
A non-contagious bacterial disease where the necrotic muscle appears black and dry, with tiny gas bubbles just visible in the tissue
Can be fatal within 12-24 hours
What causes blackleg?
dirty injection sites
bacteria in soil ingested by cattle when grazing

What part of the cow is the most expensive cut of meat?
Loin
