  • Generate more $ than any other agricultural enterprise

The beef industry5

Warm up2

  • What type of beef cattle do you typically see around where you live?

Lesson essential question3
Lesson Essential Question

  • What are the segments of the beef industry?


  • Know and understand how the beef industry operates based on segments

4 segments
4 segments

  • Purebred operations

  • Cow-calf operations

  • Stocker operations

  • Feedlot operations

  • Fill in organizer as we go

Purebred operations
Purebred Operations

  • Cattle used as dams and sires of calves grown for market

  • Allows improvement and accentuation on stock

  • Shows to select the best

Cow calf operations
Cow-Calf Operations

  • Calves grown out and sent to market

  • Crossbred animals

  • Centered in Southern and Western states

    • Weather for winter calving

Cow calf operations1
Cow-Calf Operations

  • Cows fed roughage as grass or hay

  • Cows left on free range to have their calves

  • Calves sold upon weaning

    • Good health, vaccinated, castrated


  • Step between weaning of calves and finishing (fattening) prior to slaughter

  • Weaned calves weighing 300-500 pounds placed on pasture and fed rations to promote skeletal and muscular growth


  • Stocker purchases from cow-calf producer and sells to the feedlot

  • May also be operator of feedlot

    • Fewer transportation costs


  • Final phase before slaughter

  • Fed high concentrate ration to put on proper amount of fat

  • Midwest- produces more grains


  • Range in size

  • When proper degree of finish, they are sent to the slaughterhouse

  • Generally 18-24 months old and can weigh 800-1,500 lbs

Graphic organizer beef cattle segments
Graphic Organizer: Beef Cattle Segments

  • Design a flow chart for the segments of the beef cattle industry.

  • Where do the cows start? Where do they go? What happens when they get there? Where do they go from there? Where does it end?

Segment story
Segment Story

  • Get out a sheet of paper. YOU are a calf. Write a story about your journey through the segments of the beef industry. Be sure to include all steps and be as descriptive as possible. At least a page!

    • Correct the false

  • Fill in the Blanks

  • Discussion Questions

    • Answer in complete sentences


  • Dam-the mother of an animal

  • Sire- the father of an animal

  • Roughage- a feed low in carbohydrates and high in fiber content


  • Weaned- a young animal no longer dependent on its mother’s milk

  • Finishing- fattening

  • Ration- the feed allowed for an animal in a 24 hour period

Exit question3
Exit Question

  • Describe the beef industry in an analogy. Explain your analogy in 3 sentences or more.

  • Example:

    • The Beef industry works like an assembly line. Each section has its own job to reach the finished product.

Warm up3

  • Name the breed of beef cattle that originated in the highlands of northern Scotland, the first imported to the US in 1873 and can be used for milk and meat.

Lesson essential question4
Lesson Essential Question

  • What type of feed is required for beef cattle?


  • Provide students with knowledge of feeding industrial beef cattle

  • Know needed nutrients for cattle


  • Beef cows need most nutritious diet during late gestation and lactating

    • Why do you think so?

  • Dry ( not lactating), gestating mature cows require little energy and protein


  • 2 types of forages

    • Pasture or range grasses

      • Fed during the growing season

    • Stored forages

      • Hay or silage

      • Fed to dry, pregnant cows in winter


  • Depending on size and use cows consume 25 to 30 lbs of hay per day

  • Beef cattle are raised in areas that require 110+ acres per cow-calf pair


  • Intensive Rotational grazing

    • Cattle allowed to access grass for a day or two.

    • 1-1.5 acres can support cow-calf pair for a year


  • Bulls can be fed stored forages when not breeding

  • Require grain before, during and after the breeding season

    • Why do you think so?


  • Heifer calves fed a grain ration during their first winter

    • Make sure they are heavy enough for breeding at 13-14 months


  • Bulls, cows, and heifers should have access to salt and minerals at all times

  • Cattle will self regulate their mineral intake


  • Finishing cattle are fed a high-grain, high-energy diet containing little forage.

    • Rapid gains and higher carcass quality

    • Add the pounds!

Feedlot diet
Feedlot Diet

  • Fed low grain amount at first

  • Gradually increased until 80-90% of diet is grain

  • Require supplemental protein

Feedlot diet1
Feedlot Diet

  • Monensin and Lasalocid given to increase weight gain and feed efficiency

    • How do you feel about your beef given steroids?

  • Frame size affects how finishing cattle should be fed

  • Are you growing bones late? Or just muscles?

  • Larger boned cows take longer to finish

Feedlot diet2
Feedlot Diet

  • Small-framed cattle- low energy grower grain mix

    • Increase lean muscle growth

  • Average- high-energy grain

    • Increase muscle growth

  • Large- high-energy grain mixes

    • Increase bone and muscle growth


  • Silage- a crop, such as corn, that has been preserved in its succulent condition by partal fermentation


  • Intensive rotational grazing- Cattle allowed to access grass for a day or two.

  • Bull- a male bovine that has not been castrated

  • Heifer- a female bovine that has not produced a calf


  • Read the Articles to complete a compare and contrast essay on grain fed vs. grass fed beef cattle.

  • Graphic Organizer to follow!

Parasites and Diseases

Warm up4

  • Do you think cattle should be allowed free range of feed or continue the way it has been going?

Lesson essential question5
Lesson Essential Question

  • What are some parasites and diseases common in beef cattle?


  • Learn about common diseases and parasites

  • How to treat these diseases and parasites


  • Each group will be given a name and information on a certain disease or parasite. This group will read the information and will teach the class what they have learned. Include causes, symptoms and treatment.


  • Mange mites infest hide of cattle

  • Treat with dip in treatment solution


  • Stomach worms

    • Oral wormers are effective

  • Worm eggs at bottom of grass plants

    • Overgrazing increases chance

    • Pasture rotation helps treat


  • Wasting disease

  • Symptoms similar to Johne’s

  • No signs

  • Infected through contaminated water


  • Herds periodically tested

  • Positive animals removed

  • How is beef marketed?


  • Simple

  • Shelter or windbreak in the most bitter weather

  • Thick trees or brush
