According to the video shown in class, why are hairballs considered undesirable in
ruminants and other animals. - ANS-They take up space which decreases the amount
of food an animal can hold in its GI tract. (restricts gut fill)
Along with providing feed for them, list 2 things or conditions that the host animal
provides for the rumen microbes to survive and thrive. - ANS-pH, temperature,
digestion, remove waste
Contrast the breakdown and absorption of starch and cellulose in the pig, horse, and
goat. Indicate the main structures where starch and cellulose are broken down and
absorbed for each animal and also indicate what end product(s) are absorbed into the
bloodstream for each animal from this breakdown. Also indicate what (if anything) is
excreted by each animal when digesting this starch and cellulose. - ANS-
Contrast the disease-causing methods of action of protozoa and bacteria. -
ANS-protozoa - single celled, larger than bacteria, host specific, damage digestive tract,
hinder digestion and absorption
bacteria - single celled, shape, size, host specifity, pathogenicity, damage host cells with
toxins
