  1. The Dairy Industry

  2. Dairy Industry • Provides milk and other dairy foods to consumers in North America and many foreign markets.

  3. Beginnings • Dairy cows were first brought to America in 1611. • Early farms had only one or two dairy cows for their own use. • Lack of refrigeration made it more difficult for people living in large cities to obtain milk.

  4. The Dairy Industry • Pasteurization, refrigeration, and bottled milk were developed in the second half of the nineteenth century. • This allowed milk to be stored and transported to populated areas.

  5. The Dairy Industry • Small family dairy herds began to develop in response to improved storage and handling technology. • Today there are 9.1 million dairy cows on farms in the United States.

  6. The Dairy Industry • These 9.1 million cows annually produce nearly 165 billion pounds of milk. • Each dairy cow, on the average, produces nearly 18,000 pounds of milk a year. • This is more than 3 times the production in 1950.

  7. The Dairy Industry • Today, one dairy cow provides 25 people with their dairy product needs.

  8. The Dairy Industry • The number of farms with dairy cows has declined. • There are 95% fewer dairy farms today than in 1950. • Each dairy farm is larger today.

  9. The Dairy Industry • Most herds range from 35 - 500 cows. • Some herds have as many as 10,000 cows.

  10. The Dairy Industry • Biotechnology has contributed to the changing dairy industry. • BST for example - • Giving additional bovine somatotropin to cows causes them to milk at higher levels for a longer period of time in well-managed operations.

  11. Dairy Cattle • Dairy Cattle belong to the family bovidae, which includes ruminants with hollow horns. • Members of this family also chew their cuds.

  12. Conformation • The udder should be well attached and have the capacity to hold 50 - 70 pounds of milk. • Four teats should be shaped and spaced uniformly for machine milking.

  13. Conformation • Cows also need good body capacity to hold feed for digestion. • They should regularly reproduce. Milk production is associated with the reproductive cycle.

  14. Conformation • The gestation period for a cow is 283 days. • Dry period - Milking is stopped and they are dried up 50-60 days before the next calving.

  15. Judging Dairy Cattle • When judging dairy cows the most consideration is given to the udder. • Scoring: TOTAL - 100 • Udder - 40 points • Frame - 15 points • Dairy Character - 20 points • Body Capacity - 10 points • Feet & Legs - 15 points

  23. Dairy Terms • Cow – Mature female dairy or beef animal. • Bull – Male dairy or beef animal. • Heifer – Young female dairy or beef animal. • Calf – Young male or female dairy or beef animal. • Steer – Castrated dairy or beef animal.

  24. Dairy Terms • Lactation – When a cow is milking. Typically a cow will milk for 305 days out of a year. • Colostrum – first milk from a mammal; full of antibodies. • Dry Period – Time when a cow is not giving milk (rest period before calving). • Gestation – When a cow is pregnant. It takes 283 days or 9 months for a cow to have a calf.
