lower amount of laborers needed Silage • Corn silage is better quality than wheat or sorghum • Silage is now kept in open air instead of in silos o In silos: risk spontaneous combustion due to silage using up oxygen (also lead to  farmers passing out in silos) Visiting Farms • Start with calves then move to older cows due to non-advanced immune system of calves Facility  • Higher ceilings: better lighting (want 16 hours of light) and better ventilation • Cows spend most time eating, lying down, ruminating o Importance of enough feed bunks and free stalls Factors Affecting Industry • Low milk • Reproduction  • Feet & legs • Mastitis  Friday, January 13th Dairy Product Availability • Fluid milk down 37% since 1970 o Lower-fat milk has slightly increased (“health-conscious”) • No major changes in frozen dairy products • Cheese consumption has drastically increased o Fast food and pizza The Reality of Dairy Cattle • Milk is easy to harvest • High protein contributor • Efficient conversion of feed to protein o Also conversion of low quality feeds • Foster Mothers of the Human Race How is the Industry Looking? • Number of animals? • How many lbs of milk our dairy cows produce? • Any current trends in the industry • Can you guess which state is the top milk-producing state? o California, Wisconsin (cheese), Pennsylvania • How about: where do you think GA ranks among all states in total milk production? o Pretty low, because of difficult environmental issues (heat, humidity) Top Producing States for 2015 State 2015 # Cows  (1,000 head) Change  from 2014 2015 lbs of milk  (billion lbs) Change  from 2014 California 1,775 --- 40.1 -5.2% Wisconsin 1,280 --- 29.0 +4.3% Idaho 620 --- 14.11 +1.5% New York 587 1.3% 14.1 +2.9% Pennsylvania 530 --- 10.8 +0.9% Florida 125 --- 2.5 --- Georgia   85 +5% 1.8 +5.9%

• (don’t need to memorize numbers) • New Mexico & Arizona sometimes pop up in the top 5 too • Georgia: ranked 23; Florida: ranked 18 (usually in the top 15) o Don’t want to transport milk to Florida so it’s important to make it in the area where  it will be consumed Reflecting on 2015 • Highest milk production/head? o Colorado at 25,685 (Michigan, Arizona) ▪ Used to be New Mexico • Lowest milk production/head? o Alaska at 11,667 (Alabama, Arkansas) • Georgia rankings? o Producing 21,665/head (19th ranking) ▪ Beat Florida in efficiency of cows o 23rd in total pounds of milk produced o Important for our fluid milk to stay fluid (why we use Holsteins) Monthly Milk Production • A lot of variation in milk production throughout a calendar year • Can almost see lactation curve Trends • Smaller operations (<200 cows) drastically decreased o Almost 30% in 6 years • Large increase in CAFOs  o Over 100% increase • ***Farms are getting larger*** • ***Number of farms are declining but # of cows/farm is increasing*** • ***Milk cows in the US is staying relatively stable*** • ***Amount of milk produced per cow is rapidly increasing*** • ***Population of cows are moving west*** o Creating cow islands? Large pockets of growth in cow #s ???? bioterrorism,  population density, environmental issues, monopolies/conglomerates Typical US Dairy Industry • Average dairy cow in the US: o Produces 22,588 lbs of milk/year o 8.6 lbs per gallon o ~2588 gallons per year • Typical American dairy farm: o Family Owned and Operated (97%) o Average farm has 187 milking cows • Is some of the family farm definition changing?o Milking 2,000+ cows Why Load Them Up and Move Them West? • Climate o Housing o Pollution • Quality and availability of feedstuffs o Most corn is raised in the Midwest • Population Shift o Transportation • Available land Why Stick to Your Guns in the East? • Milk deficit area ???? primary reason o Supply/demand = $$$ (profits may be greater due to higher milk price) • Access to large markets along eastern seaboard o Important for exports • Cheaper land prices in rural areas Milk Price • Federal government dictates how we get paid for us (set minimum, not cap) o Set based on supply and demand ▪ California has higher supply than demand ???? low pay price ▪ Georgia has lower supply than demand ???? high pay price o 10 milk marketing orders (US broken down into regions) • Most milk is shipped to milk co-ops, essentially brokers for milk  o Can only increase price; can’t go below government’s minimum • January 2017: $21.75 per 100 lbs of milk  • February 2016: $17.94 per 100 lbs of milk  o Doesn’t seem like a large difference but it adds up to a monumental difference • August 2014: $28.17 per 100 lbs of milk  • If paid for protein, rise in total price
