DAIRY INDUSTRY/ DAIRY SCIENCE “INTRODUCTION TO THE DAIRY INDUSTRY”

OBJECTIVES 1. The student will discuss the historical development of the dairy industry. 2. The student will explain the importance of the dairy industry in California and the United States.

I.Introduction to the Dairy Industry

A. History of the Dairy Industry 1611 – Cows first arrive in the U.S. at the Jamestown Colony in Virginia – Cows reach the Plymouth Colony – First regular shipment of milk by rail – Orange County to New York City – Beginning of Pasteur experimentation.

1857 – Gail Borden received first patent on condensed milk from both U.S. and England – Continuous centrifugal cream separator invented by Dr. Gustav De Laval – Milk bottle invented by Dr. Hervey D. Thatcher, Potsdam, New York – Automatic bottle filler and capper patented – Tuberculin testing of dairy herds introduced. Test for fat content of milk and cream perfected by Dr. S.M. Babcock.

1891 – Certified milk originated by Dr. Henry L. Coit in Essex County, New Jersey – Commercial pasteurizing machines introduced – First compulsory pasteurization law (Chicago) applying to all milk except that from tuberculin tested cows – Automatic rotary bottle filler and capper perfected – Tank trucks first used for transporting milk

1919 – Homogenized milk sold successfully in Torrington, Connecticut – Ways of increasing Vitamin D in milk made practicable – First plastic coated paper milk cartons introduced commercially – Fluid milk included in Army ration – First farm bulk tanks for milk begin to replace milk cans – Every-other-day milk delivery started (initially as a war conservation measure).

1946 – Vacuum pasteurization method perfected – Ultra-high temperature pasteurization is introduced – Milk vending machines win place in distribution – Flavor control equipment for milk is introduced commercially – Plastic milk container introduced commercially 1967 – Non-dairy milk substitutes introduced in several markets.

1968 – Official acceptance of electronic testing for milk fat content – Nutrition labeling of fluid milk products – Metric measurement equivalent introduced – American Dairy Association launches the national introduction of the “Real” ® Seal dairy symbol – UHT (ultra high temperature) milks gain national recognition.

1983 – Creation of National Dairy Promotion and Research Board – Lower fat dairy products gain widespread acceptance. Low fat plus skim milk sales exceed whole milk sales for first time – Mandatory animal drug residue testing program established – Bovine Somatotropin approved for commercial use in U.S – Launch of processor-funded milk mustache advertising campaign.

B. Economic Importance to Agriculture 1. $27,367,858,000 of Cash Receipts from Farm Marketings of Dairy Products in 2004 in the US. ($21,238,737,000 in 2003, $20,582,238,000 in 2002, $24,709,749,000 in 2001) 2. Leading Agriculture Commodity in California a. Milk – $5,226,738,000 in 2005 $5,351,273,000 in 2004 $4,039,818,000 in 2003 $3,835,347,000 in 2002 b. The amount is out of a total of approximately $40 billion in Total Agriculture Products. c. This is approximately 13% of the total value of all agriculture products produced in CA.

D. Milk and By-Product Consumption and Trends 1. Changed in consumption of milk/milk products over the past 20 years.

E. Milk/Dairy Facts 1. Most dairymen milk twice per day however there is more of a trend to milk three times per day. 2. Standard lactation of a diary cow is measured based on a 305-day lactation. 3. Cow numbers in 1950 were 24,000,000 with production about 5,000 lbs./lactation or 16 lbs./day or 1.9 gallons/day. 4. The milk price in 1985 was $13.50/cwt. Today the milk price is $11.10/cwt. Or about $.95/gallon. 5. The retail price of milk today is approximately $2.89 per gallon.

G. How to get into the Dairy Business 1. Inherit 2. Marry 3. Work into partnership

H. Advantage of the diary business: 1. Dairy cattle used for feed roughages that might otherwise be wasted. 2. Dairying provides a steady income throughout the year. 3. Labor is used throughout the year. 4. Death losses in the dairy herd are usually low if good management is followed. 5. Soil Fertility is maintained.

I. Disadvantages of the Dairy Business: 1. A high capital investment is needed. 2. The labor requirement is high and the operator is confined to a regular schedule of milking. 3. Training and experience are needed before entering into the dairy business.

4. Many management skills needed: a. Financial Management b. Basic Sciences c. Herd Health Management d. Breeding (Genetics) e. Nutritional Management f. Production Records g. Etc. 5. It takes a relatively long time to develop a high- producing dairy herd. 6. The demand for dairy products appears to be dropping. 7. Federal, State and local regulations are increasing.
