The Changing Industry
Farm Population % % % % % %
Farm Size acres acres acres acres acres
When and How Farms Have Changed Major shifts occurred in the 40’s and 50’s Farms became more specialized Increased efficiency as a result of specialization In 1940 one farm could support 18.5 people Today one farm can support 135 people
Why US Farms are so Productive Our Economic System Land and Climatic Conditions Our Educational Systems Specialized Agribusiness
Significant Agriculture Legislation Morrill Act 1862 Provide a portion of federal land in each state to establish a college Land-Grant College Act 1862 Established the “agricultural college” concept Hatch Act 1887 Established research funding for Land-Grant colleges (Experiment station) Smith - Lever Act 1914 Financed the county agent extension system to get research information to the people (Cooperative Extension)
Sources of Agricultural Information Food and Agriculture Organization (FAO) Established by the United Nations in 1945 Collects, evaluates, and disseminates information on world trends in food and population Council for Agricultural Science and Technology (CAST) Formed in 1972 to identify food-related issues and interpret related scientific research
Role of Animals High Quality Protein Foodsource Diet Palatability Land Use and Conservation Food Economy Companion Animals
Concerns for Animal Production: Can the earth’s land and water produce enough food for the growing population? Should we feed animals as intermediaries in the food chain? Why do humans “prefer” animal products in their diet?
Beef Industry Seedstock Producers Commercial Cow-Calf Producers Yearling/Stocker Operator
Seedstock Purebred producers Concerned with genetics Concerned with appearance Body composition Color Show cattle
Cow-Calf Production Involves some 33 million head of beef cows distributed throughout the country Most are concentrated in areas where forage is abundant 16 states have over 700,000 hd each 75% of the US total Approx. 60% of the 850,000 beef cattle operations have less than 50 hd per operation
US Beef Cow Operations and Inventory Operations Inventory Herd Size (No. Cows) Percent of Total
Stocker/Yearling Production Cattle are fed for growth prior to their going into the feedlot for finishing Primary basis is to market available forage and high-roughage feeds Grass, crop residue, wheat pasture, silage More desirable for early maturing cattle Larger framed, later maturing cattle are more efficient and profitable if they go directly into the feedlot
Stocker/Yearling Production Packer Feedlot Weaned Cattle Wintered or Custom Lot Summer Grazing Wintered Summer Grazing
Feedlot Cattle fed in small pens where feed is brought to them on a daily basis Approx. 23 million feedlot cattle are fed in various states Fed a high grain diet 95% of feedlot cattle are fed in feedlots with over 1000 head capacity A few have capacities over 100,000 head
Beef Industry Feeders Packers Retailers Consumers
Dairy Industry Larger Farms Dominate 9% of Dairies produce over 1/2 total milk 70% of the US dairy herd is concentrated in large dairies of over 100 cows These dairies represent just 20% of all US dairies Movement of dairies Specialization of Farms Feeding systems
Horse Industry 1997 approximately 6.9 million horses in US Used primarily as recreation or companion animal 43% recreational activities 29% show 10% racing Remainder used for rodeos and work In 1997, 200,000 Horses slaughter in US How many are slaughtered today?
Poultry Industry Dramatic changes in 60’s and 70’s Integration Corporate owned operations Control of all segments of the growing and processing is by one company
Broiler Production Most are contract grown for a company ConAgra Tyson Pilgrims Operator owns houses, equipment and furnishes labor Contractor furnishes, birds, feed, field service, dressing and marketing
Broiler Production Payment is made in relation to a group of producers assigned as a contemporary group The better the operation does in relation to its contemporaries the higher the bonuses
Sheep and Goat Industry Versatile and efficient, especially in developing countries Tend to be more well adapted to arid tropical climates than cattle Often grazed in tandem with cattle because they utilize different forage sources
Sheep and Goat Industry Goats tend to be more efficient browsers Sheep prefer short grasses and some broadleaf weeds and other plants World sheep numbers in 1999 were the highest on record Primarily in China, Australia, India, Iran and New Zealand
Sheep and Goat Industry Purebred breeders Commercial market lamb producers Commercial feedlots
Swine Industry Beginning to go the direction of the poultry industry Corporate contracted growing China is far and away the leader in swine numbers As in dairy industry farm number is declining while production increases
Swine Industry Four major swine operations Feeder pig production Feeder pig finishing Farrow to finish Seedstock producer

Adaptation Adaptation – the sum of the adjustments that occur in an organism that promotes its welfare and survival in a specific environment Agricultural animals must have the ability to adapt to both the natural and man made environments The symbiotic relationship is key in domestication of animals
