Feeds and Feed Label Objectives:  Identify sources of nutrients and classes of feed.  Identify vitamins, minerals, and feed additives. A Little Review  Can anyone tell me what we talked about yesterday?  Can anyone remember and name the 6 essential nutrients?  Can someone tell me what palatability means?  Can someone tell me the two- types of vitamins there are? Basic Nutrients and Their Function  Regulatory  Energy  Water  Protein  Minerals  Fats  Proteins  Carbohydrates  Vitamins  Structural  Minerals  Proteins  Fats Water  Cheapest and most abundant nutrient  Most important  Functions:     Regulates body temp. Nutrient/waste transportation Aids in digestion/absorption Regulate ionic concentrations Carbohydrates  Occurance:  Plants 60-80%   Cell content- sugar and starch Cell wall- cellulose and hemicellulose  Different classifications  Can anyone name some classifications of carbohydrates?  Functions:  Energy  Heat  Building Blocks  Fat Disposition Fats (Lipids)  Contain 2.25x more than carbohydrates  Functions:     Dietary energy supply Source of heat, insulation, and protection for the body Sources of essential fatty acids Serve as a carrier for absorption of fat- soluble vitamins  Classification:  Simple  Compound  Derived Protein  Principal component of organs and soft structures in the body  Digestible protein- portion of crude protein which the animal digests  Crude protein- composed of true protein and any other nitrogenous product  Functions:  Structural- collagen, elastin, blood proteins  Body metabolism- enzymes, hormones, immune antibodies  Distinct functions- defense mechanism, hooves, cell membranes Minerals  Natural Sources    Forage plants Grains Macro Minerals normally preset at greater levels in the body or needed in relatively large amounts in the diet Ca, P, Na, Cl, Mg, K, S  Micro  Normally present at love levels in the body or needed in very small amounts in the diet  Co, Cu, F, I, Fe, Mn, Mo, Se, Zn  Functions:       Structural and skeletal development Function in protein synthesis Oxygen transport Fluid balance Regulating acid-base balance Activation of many enzyme systems Vitamins  Fat soluble- A, D, E, K  Water soluble- thiamine, riboflavin, niacin, pyridoxine, pantothenic acid, biotin, choline, folic acid, B12  Functions:  Regulators of metabolism  Growth and maintenance of life  Antibody synthesis  Requirements increase with age Now  Take a minute to look at the feeds in front of you  Fill out the worksheet to the best of your ability.  What are the feed additives added to the feeds in front of you?  What do you think those additives are used for? Objectives  Identify sources of nutrients and classes of feed.  What sources of nutrients and classes of feed did we look at today?  Identify vitamins, minerals, and feed additives.  What kind of vitamins, minerals, and additives did we find in the feeds we looked at?
