  2. Today we will cover… • Objectives • Importance of nutrition • Definitions • 6 essential nutrients • Water • Carbohydrates • Fats • Proteins • Minerals • Vitamins • Relevance to FFA/SAE • Video

  3. Objectives • CLF 261 • List the 6 classes of nutrients • Understand the function of each nutrient

  4. Object of Nutrition • Obtain & utilize surplus/unusable feed stuffs & convert them to desirable products http://catlovingcare.com/wp-content/uploads/2009/08/13/should-cats-eat-raw-chicken-and-uncooked-meat/Raw-Meat-cat-food-natural-diet-1l.jpg http://farmersandartisans.com/wp-content/uploads/et_temp/milk-eggs-78660_184x184.jpg

  5. Why is nutrition important? • Nourishes the body • Energy • To maintain a healthy lifestyle • To grow and become strong • Reduce diseases • Guides managers/growers to meet their livestock objectives

  6. Definitions • Nutrient: • Food that provides nourishment essential for growth and maintenance of life • Digestible Nutrient: • Part of anutrient • Digested and absorbed

  7. Definition • Carbohydrate (CHO) • Compound made up of oxygen, hydrogen and carbon • Form of energy for most organisms http://www.photo-dictionary.com/photofiles/list/1115/9194corn.jpg

  8. Definition • Fat (Lipids) • Also source of fuel • Made up of carbon, oxygen and hydrogen • Provide more energy than carbohydrates http://lidiasitalyblog.com/uploads/2010/12/olive-oil-300x239.jpg

  9. Definition • Protein • Carbon, hydrogen, oxygen, and nitrogen (16%) • Also a source of fuel • Act as enzymes Blood Meal http://www.extremepumpkinstore.com/media/ecom/prodlg/blood-meal.jpg Soybean Plant http://www.igece.org/SystemsBiologyCenter/IMG/soybean-pod.jpg

  10. Definition • Mineral • Inorganic compound found in nature • Ex: Di-calcium Phosphate

  11. Definition • Vitamin • Vital nutrient provided to animals in small quantities • Organic compound

  12. Definitions • Starch • Carbohydrate joined by many glucose molecules • Found in potatoes, wheat, rice • Glucose • Source of energy • Cellulose • Found in cell wall of green plants Wheat Plant http://i1.tribune.com.pk/wp-content/uploads/2011/01/Wheat12111-640x480.jpg

  13. Check For Understanding • Any questions from the definitions?

  14. What are the 6 essential nutrients? • Water • Carbohydrates • Fats • Proteins • Minerals • Vitamins

  15. Water • Largest portion of plants and animals • Controls body temperature • Transport nutrients • Helps in digestion of feeds • Is carrier for waste-products • Makes up 70% of plants & animals http://www.pigprogress.net/public/image/scaled/article-9279-285x210.jpg

  16. Carbohydrates • Provide energy for • Body functions, growth, fattening, reproduction • Largest part of animal’s food supply • Usually fibrous part of diet • Includes sugar, starch and cellulose http://www.freestockphotos.biz/pictures/10/10144/cows.jpg

  17. Fats (Lipids) • 2.25x’s more energy than carbohydrates • Provide energy reserves, protect organs, insulate body • Found in every cell of body • Larger proportion of carbon and hydrogen than CHO

  18. Proteins • Made up of: • amino acids- building blocks • Needed throughout life for growth & repair • Form: • Muscles, internal organs, skin, hair, wool, feathers, hoofs, & horns http://howstuffworks.files.wordpress.com/2010/10/sheep-wool.jpg

  19. Minerals • Found in: • Bones & teeth • Make up important parts including blood • Affect heartbeat • Depends on mineral balance to maintain its regularity • Calcium, sodium, and potassium are involved http://2.bp.blogspot.com/-4q3 OQOEEWQ/TtM25vA93iI/AAAAAAAABRE/X-o_Gz05PLM/s1600/OysterHenTreeExtCUnight.JPG.JPG

  20. Vitamins • Essential for life and health • Provide a defense against disease • Promote growth and reproduction • Contribute to animals overall health http://www.ars.usda.gov/is/graphics/photos/animalsimages.new.htm http://www.ars.usda.gov/is/graphics/photos/animalsimages.new.htm

  21. FFA/SAE Opportunities with Nutrition • Students raise a healthy animal for the fair • Responsibility • Learn nutrition requirement for each animal • Cattle, sheep, goat, pig, chicken

  22. Review • Define what a nutrient is • Name the 6 nutrients • Explain the role of each nutrient
