1

Camelids appear to utilize feed more efficiently than ruminants because the y have

A. more frequent rumination
B. more rapid absorption of volatile fatty acids
C. a higher metabolic rate
D. lower maintenance energy requirements

T/F:
The cross between a llama and an alpaca is a huarizo. Llamas and alpacas can interbreed and produce fertile offspring because both species have 37 pairs of chromosomes

T

3

T/F:
Llamas and alpacas are herbivores and are considered pseudo ruminants because they have two fermentation compartments prior to the true stomach, or abomasum

Huacaya alpacas are hardier, more common, and have fleece with more crimp, but ______ (breed) alpacas have lustrous fibers that hang down in the "dreadlocks". Castrated males of both breed would be called ________

suri
geldings

6

Compared with llamas, alpacas
A are larger (~500 vs 185 lbs max size)
B have shorter gestation lengths (335 vs 350 days)
C produce finer fiber
D are seasonal breeders, not induced ovulators

7

T/F:
Llamas can generally meet their daily maintenance energy requirements by consuming 1% to 1.25% of their body weight in hay on a dry matter basis.

10

Net energy provided by a feed

A is higher from starch than cellulose
B will typically be higher from forage than grain
C decreases as lignin content increases
D is used for maintenance and production

ACD

11

Milk fever
A. can be prevented by feeding high calcium levels in the close-up ration
B. is most common in cows during their first lactation
C. is caused by hypercalcemia
D. causes cow to be at a higher risk of mastitis

D

12

Regarding Mastitis

A. Escherichia Coli is the most common environmental cause
B. Mycoplasma infection has not treatment and requires culling of the cow
C. Staphylococcus Aureus is a "chronic" infection that is difficult to treat
D. somatic cell counts > 400,000 cells/mL often indicate an infection

ABCD

13

A llama

a. is an induced ovulatory like a cat
b. has a corkscrew cervix like a pig
c. has a -350 day gestation period, like a horse
d. is a pseudo ruminant with fermentation vats
e. seasonal breeders, like most sheep
f. are larger, but produce coarser fiber than alpacas
g. hind-gut fermenters

ABCDF
