what are some general safety guidelines for cattle (14)
Move slowly and deliberately
Be cognoscente of and confident in your movements
Do not make sudden movements, noises, etc.
Do not sneak up on cattle/let them know where you are located
Do not chase the cattle
Try and be quiet
Never go between a mother and her calf
Always know your escape route
Nearest gate, nearest fence, nearest alleyway a bovine cannot fit into, etc.
Do not work with bulls without experience and training
Never trust a bull
Beef bulls are not as bad as dairy bulls
Remains calm and deliberate in your movements
Be aware of your surroundings
Listen to all instructions and follow them immediately
When working with an individual bovine stand close to the bovine you are working with (this is also true for all livestock species)

how long is cattle gestation

what are the two options for calves after weaning

most cattle are in which states (3)
the great plains states, the corn belt, and the southeast
what is th elargest cost of cattle operations
feed
how do cattle operations combat the cost of feed
being located near the feed
what is another name for yearling/stocker production
backgrounding
what is the goal of yearling/stocker productions
add weight to weaned calves prior to feedlot or slaughter
some larger weaned claves may _
go straight to feedlots
when are calves purchased for yearling/stocker productions
fall or spring
what are animals typically fed in yearling/stocker productions
grazable forage from 12- 20 months of age
what is cattle feed dependent on (3)
location
time of year
forage availability
how much do cattle gain per day at yearling/stocker operations
1-1.5 lbs
what weight do calves enter and leave yearling productions
500; 800
what is the purpose of feedlot operations
feed cattle high energy diets to prepare for harvest by increasing weight
what are the main aspects of meat
muscle — protein
fat — palatability
in feedlots bovine will gain _
3 or more pounds a day
in feedlots animals are housed _
close to feed, water, shelter, etc.
at what weight do cattle finish at the feedlots
