Global Food SupplyA. Cereal Grains= wheat, corn50 % calories45% proteinsB. Animal Products16% calories37% proteins- Have more proteins for humansII. Importance of Animal Protein in Human DietsA. “Biological value”- Meat has a high “biological value”- Amino acids make-up matches human requirements- Digesting muscle to make muscle comes from amino acidsB. Essential Amino Acids- All essential amino acids are present in the correct proportions- Essential amino acids have to be present in your body for you to liveC. B-Vitamins- Animal Products are excellent sources of b-vitamins and the only natural source of vitamin b12.III. Available Food SuppliesA. Developed Countries: W. Europe, U.S., CanadaB. Developing Countries: India, Sub-Saharan Africa**RDA calories: Male 2,700. Female 2,000. RDA protein: Male 56.

Developing Countries3% calories10% proteinB. Developed Countries30% calories60% protein(consume mostly from animal products)IV. Facts- Agriculture in Developed vs. Developing Countries- Major difference: money & mechanization- About 20% of the world’s tractors in U.S.- In 2005, 2% of U.S. population fed 98%- One farmer fed 94 U.S. and 34 World Citizens (128 people)A. Developing Countries*Use animals for workB. Percent of Disposable Income Spent on Fooda. Americans = ~11%b. Developing Countries = 30-60%V. Reasons for Inadequate Food Supplies1. Lack of Knowledge2. Population Concentrationa. Asia- 50% people / 22% agriculture productionb. N. America- 6% people / 27% agriculture production3. Lack of Wealtha. Mechanizationb. Fertilizer4. Government Policies Support or lack thereof Government used to control people5. Environmental Challengesa. Lack of arable landb. Lack of rainfallc. Plant/animal diseases6. Religious or Social TabooVI. 2013 U.S. Beef Cow Inventory (US- 29.3million): Mostly mid US1. Texas- 4 million GA= #212. Nebraska- 1.8 million3. Missouri- 1.8 million4. Oklahoma5. South Dakota6. Montana7. Kansas8. Kentucky9. Iowa10. North Dakota11. Tennessee12. Florida**Why this area?? Grazing lands Not really populated Lot of crop productionVII. 2013 U.S. Cattle-on-Feed Inventory (US 13.6 million): Mostly Mid-West**Confined and fed grain/corn, not grass right before slaughter1. Texas- 2.8 million GA: NOT EVEN ON THE LIST.2. Nebraska- 2.6 million3. Kansas- 2.2 million4. Iowa5. Colorado6. California: Dairy Cattle7. Oklahoma8. Minnesota9. South Dakota10. Arizona: Dairy Steer/Heifers11. Idaho: J.R. Simplot uses bi-products from potatoes to feed cattle** Cattle out of Thermo-Neutral Zone: DO NOT REALLY EAT VIII. 2013 U.S. Dairy Cow Inventory (US 9.2 million)1. California- 1.8 million GA= #252. Wisconsin3. New York4. Idaho5. Pennsylvania6. Minnesota7. Texas 8. Michigan9. New Mexico10. Ohio**CA is the #1 state in fluid milk production**WI is the #1 state in processed dairy productionIX. 2013 US Hogs and Pigs Inventory (US 65.9 Million)1. IOWA!!!- 20.5 million: So concentrated here that prices soar because Iowa dictates the price!2. North Carolina- 8.7 million3. Minnesota4. Illinois5. Indiana6. Nebraska7. Missouri8. Ohio9. Oklahoma10.
