QUESTIONS AND MODEL RESPONSES

◉ Sources of minerals:
Answer: Calcium
-limestone (33-38% Ca), oyster shell (37-39% Ca), dicalcium
phosphate (23-28% Ca)
Phosphorus
-phosphoric acid (22-32% P), diammonium phosphate (20-24% P),
dicalcium phosphate (18-22% P)
Salt
-most fed mineral of them all (appetite enhancer/depressor), fed
free-choice


◉ Chelated Minerals
Answer: -improves their stability and utilization
-releases it in ionic form at the intestinal wall
-readily digested & absorbed


◉ Why process feedstuff...
Answer: -increase efficiency of handling

, -increase utilization (digestibility/palatability)
-alter density (increase/decrease bulk)
-improve feed efficiency (how many lbs of feed need to be fed to
increase lb in weight)
*increase efficiency, decrease cost of gain


◉ Methods of processing feedstuff
Answer: -grinding
-heat process
-chopping
-pelleting


◉ Types of feed grinders
Answer: -hammer mill (bigger holes-coarser the grain, smaller
holes-finer grain)
-burr mill (top plates rotate, bottom plate stationary)
-roller mill (form a flake)


◉ Advantages/disadvantages of grinding grains....
Answer: increased fineness of grind results
-improved feed efficiency
-faster passage through GI tract
