In Exercises 80 to 85, sketch the graph of g. a. Find the domain and the range of g. b. State whether g is even, odd, or neither.
NonRuminant Mouth 1. Food Acquisition 2. Mechanical Breakdown (mastication) 3. Saliva Add moisture Buffer (bicarb) Taste Amylase (start starch digest) ONLY primates and pigs Stomach (Monogastric) 4 regions 2 Secretions HCI – Parietal Cells (pH~2.0) Chemical reaction NOT enzymatic Pepsinogen – Chief Cells. In pH pepsin (active form) Pyloric region regulates passage of feed (digesta) Small Intestine Enzymes from S.I. and Pancreas CARBOHYDRATES Starch glucose Fiber Fiber (not digested) FATS T.G. glycerol & fatty acid PROTEIN True protein amino acids (some not digested) Nonprotein out. ~absorbed MINERALS (absorbed) VITAMINS (absorbed) Large Intestine Water absorption ~ Minerals ~ Vitamins Ruminant Mouth Food Acquisition Tongue primary important Mastication No upper front teeth Saliva Add moisture Buffer!!! NO Amylase Reticulo Rumen No enzymes from animal Bacteria ~ 2530 billion/mL Protozoa ~200500,000/mL CARBOHYDRATES Starch microbe nrg VFA Fiber microbe nrg VFA VFA absorbed from rumen wall Main source of energy FATS T.G. glycerol & fatty acids PROTEIN True Protein microbial protein some bypass goes to S.I. NonProtein N Microbial protein VITAMINS B vitamins synthesized Cobalt, cobalalmine Omasum Water absorption Abomasum True stomach HCl Pepsinogen Pepsin Small Intestine Major site of digestion & absorption by animal (digesta leaving rumen) CARBOHYDRATES Nothing, all in rumen FATS F.A. absorption PROTEIN Microbial protein amino acids Bypass protein amino acid MINERALS (absorbed) VITAMINS (feed and microbial absorbed) Large Intestine Water absorption ~ Minerals ~ Vitamins Young Ruminants Essentially monogastric – Only abomasum fuctional 3 weeks: Rumen begins to become functional 3 months: (4 mo.) fully functional Esophageal Groove: muscle, during first 34 months of life active. Nursing stimulates it closing – milk bypasses rumen and goes into abomasum. Terms Regurgitate: to east up “digested” feed to the mouth. Ruminate: Regurgitation, chewing, reswallowing. Eructate: Eliminating of gas via belching. Gas produced by bacteria and protozoa CO 2and CH 4 Bloat = inability to expel gas Swallow Regurgitate Chew bolus Reswallow Another bolus regurgitated. Rumination = Regurgitate Chew bolus Reswallow NonRuminants Herbivores *See monogastric NonRuminant* Large Intestine Cecum (pocket) ~ Same as rumen But CP (crude protein) No. Starch No. Fiber VFA (Absorption) B Vitamins Synthesized. Rest of L.I. Water Absorption ~ Minerals ~ Vitamins (B Vit.) Digestion of Cellulose Pregastric digestion Postgastric digestion
