There are over 80 recognized breeds of beef cattle in the US. A breed is defined as a group of animals with common descent and distinctive characteristics. Each breed has advantages and disadvantages related to traits like birth weight, growth rate, fertility, milk production, and frame size. Some major beef cattle breeds discussed are Angus, Hereford, Shorthorn, Charolais, and Gelbvieh. The document then provides profiles for several specific breeds, outlining their country of origin, colors, sizes, and popularity factors. Key beef cattle characteristics discussed are mature body size, milk production, age at puberty, environmental adaptability, growth rate, muscle expression, cutability, and marbling.

19. 
There are approximately 250 breeds of cattle recognized
throughout the world, and several hundreds of breeds that are
not recognized. The exact count is impossible to determine
because other breeds continue to be imported, and crossing
existing breeds continuously creates new breeds.
Breeds of Beef Cattle

20. 
The major characteristics for beef producers:
 Mature body size
 Milk production
 Age at puberty
 Environmental adaptability
 Rate and efficiency of gain
 Muscle expression
 Cutability
 Marbling
Breed Characteristics

21. 
Mature cows weigh less than mature bulls.
Larger mature size results in:
 Heifers being older and/or heavier at puberty
 Heavier birth weights (often associated with difficult calving)
 Faster rate of gain
 Heavier weaning weights
Mature Body Size:
If various sizes of cattle are fed for the same length of time, cattle with a larger
body size will have faster, more efficient gains, lower marbling, less fat, and
improved cutablity.

22. 
The Main reason for increasing milk production in beef cattle is
to increase weaning weights of calves.
Heavy milk production can be bad—
 Heavy milking cows often produce milk at the expense of
their body functions (they get skinny)
 Thin females are less likely to come into heat and have a
harder time getting pregnant
 Heavy milkers are slow to cycle which lengthens breeding
interval and reduces general reproductive efficiency.
Milk Production

23. 
 Leaner meat means more muscle
 Most breeds that are ranked above average in muscle
expression are also above average in size.
 One concern with beef producers is that muscularity
appears to affect reproductive efficiency (calving difficulties
with bigger calves).
Muscle Expression

24. 
Age at puberty is important because cattle that reach
puberty at an earlier age conceive at an earlier age.
These cattle have the potential to have a long
productive life (economically important to cattle
producers)
Age at puberty is linked to body size, milking potential,
genetic classification, and environmental factors.
Smaller cattle with higher milk yield have been known
to mature earlier.
Cattle exposed to harsh environmental conditions,
whose nutritional requirements are not being met, reach
puberty later.
Age at Puberty

25. 
 Cutability is the percent of lean in a slaughter animal and is
directly affected by an animal’s muscle structure and directly
related to nutrition.
 Marbling (intramuscular fat) is often referred to as taste fat.
 Cattle that mature early and have high milk yields are usually
high in marbling.
