25
Define Cal or Kcal as it relates to animal nutrition
=1000 calories
26
What is umami, what foods are assisosiated with umami
Savory. Maybe high protien?
27
Do ruminants produce salivary amylase? Explain
Not technically but it is produced from the outside of the mouth on the muzzle
28
Describe size and purpose of the esophageal grove
About 2". Channels milk in young ruminants straight to the abomasum
29
Explain lactose intolerence
It means you dont have many lactase enzymes and therefore cannot digest lactose efficiantly
30
Describe an evolutionary advantage of ruminants
They ruminate. Meaning that can eat as much as fast as they want to, and then rechew later.
31
If a steer and horse were both fed oats, which would gain more weight
Horse. They digest grain before it gets to fermentation.
32
What do steer feces look like and why
Smooth, runny. No particles. Due to rumination
33
What do horse feces look like and why
Round, dry coarse. Lots of particles. Horses do not ruminate
34
What do sheep feces look like and why
Round smooth pellets. No particles. Lambs ruminate but abdorb a lot more water
35
Why would a steer fed grain gain more than a steer fed hay?
On a grain diet, you lose less energy fue to gas by producing more propionate. Eating hay results in more acetate and butrate, which produce gas
36
