3) runoff holding ponds
4) compost manure
5) parasitic wasp- biological control
What is the largest environmental factor?
What must feedlots follow, regarding water quality?
Confined Animal Feeding Operation part of the Clean Water Act. Regulated by the EPA
What 3 things go into calculating the break even cost of feeder cattle?
Price of Feeder Cattle
Cost of Gain
Sale Price of Fed Cattle
How are the break even prices of cattle applied?
Calculated on an individual lot of cattle as a unit
What is the Breakeven Price Per CWT of Live Weight formula for feeder cattle?
(cost of feeder cattle + feed cost + non-feed cost)/ estimated final weight of fed cattle
What is the Breakeven Price for cost/lb of carcass formula?
(cost of weaned calf + yearling stocker cost + feedlot cost) / carcass weight
What are the 3 factors that change of the profitability of a pen of cattle?
Poor health management
Poor rates of gain

Purchase cost of feeder animal
Daily gains (feed efficiency) (expect 6:1)
7 ways to improve feed efficiency?
Energy density of food
Processing grains (steamflaking and reconstituting)
Feeding growth additives and growth stimulants
Feed cattle to proper composition of gain
Select for genetic ability to gain rapidly
Sex of feedlot cattle
What are the factors that affect non-feed costs? (4)
What are the two factors that influence revenue?
sale price of market steers and heifers
sales (live basis vs carcass)
Why are implants and additives used?
to improve rate of gain and efficiency
How many time can they be given to an animal?
1-3 times based on the animal
What is the trade off for aggressive implants?
increase in pounds for a lower quality grade
When do aggressive implants work best?
when the Choice- Select spread is small
