Other Stuff we should know AVS 209 Flashcards
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
ABD
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
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
T
Among the lamoids, _________ have the finest wool, and nearly became extinct as a result of this.
vicuna
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
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
BC
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.
T
If phosphorus exceeds calcium in the diet, cattle may get hard aggregations of minerals in the kidney, bladder, or urethra, which cause _________. This can be fatal
urinary calculi
Malignant Catarrhal Fever (MCF) affects cattle and bison, but is carried asymptomatically by ______. The disease has symptoms similar to _________ disease.
Lambs
foot and mouth
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
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
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
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
Compared with llamas, alpacas
A are larger
B are more common in the US
C produce a finer fleece or fiber
D have slightly longer gestation lengths
C
Members of the lamoid family include
A. lambs B. llamas C. guanacos D. burros E. alpacas
