Terms | Definitions |
|---|---|
 water intake | Temperature, feed type, pasture, water type (quality), and stage of production affect this |
| Protein | Composed of amino acids, expensive, need declines with age |
| PVT | TIM HALL |
| HQ Proteins | More complete balance of AA, animal proteins are this |
| UDP RUP | "bypass proteins" meaning they will absorb in small intestine, ex. bloody fish meal |
| Fatty Acids | These can be saturated (canola oil) or saturated (lard/beef fat) |
| Fat | This has a higher density than other nutrients |
| 2 | Acetic has how many carbons? |
| 3 | Propionic carbons? |
| 4 | Butyric carbons? |
| Carbohydrates | formed by photosynthesis in plants ex. glucose |
| Glucose | Primary energy source (carbohydrate) |
| Complex | ________ carbohydrates Ex. cellulose, also called structural carbohydrates |
| Vitamins | play various roles as regulators of metabolism |
| A | Vitamin __ : found in green leafy forages, heat damages it, night blindness associated with deficiency |
| D | Vitamin __: thought to be provided by sunlight, enhance intestinal absorption, Rickets |
| E | Vitamin __: helps immune function, associated with selenium |
| K | Vitamin __: needed for blood clotting, legumes reduce this, gut bacteria produces |
| Thiamin | found in whole grains and starchy foods, needed in Krebs, young ruminants will get headache from deficiency |
| Macro minerals | you need these in larger amounts |
| Ca P | Two elements. Grains are low in it, forages are high |
| Mg | element for skeletal maintenance and enzyme problems. GRASS TETANY |
| K | element for intercellular fluids, osmotic pressure. grazing animals rarely have problem |
| S | element wool producers most need. can have toxicity problems over .4% because it will tie up Mo |
| I | Element needed for synthesis of thyroid hormones, GOITER |
| Cu | Affects nervous system, pigmentation in skin, problem in show lambs, red tinge on shoulders |
| Fe | Needed for blood, heavy parasite load can make anemic |
| Se | Most toxic element. Regulated by USDA. Excessive drooling from deficiency |
| Roughage | Plant derived material we feed for stem/leaves. Ex. alfalfa, hay, bermuda grass. "clogs em up" |
| 40 | % of roughage needed in ruminant diets |
| mid growth | prime stage for roughages |
| Carbonaceous | ________ concentrates: opposite roughages. high energy, low fiber. ex. starch, corn, sorghum grains, oats, barley, wheat, molasses, animal fats |
