Beef industry terminology Flashcards
1
Q
Average daily gain
A
- ADG
- daily live weight increases in growing animals
- expressed in kg or lb per day
- genetic potential
- farmers have ADG goals
- can indicate health
2
Q
Balance ration
A
- the 24 hour feed allowance
- is a diet often made by a nutritionalist
- provides animal with proper amounts and proportions of nutrients for a given performance
- is a mix of foods (no one food is enough)

4
Q
Describe bloat
A
- distension of the upper left side of the abdomen
- can be from a fast diet change, obstruction, nerve damage
- accumulation of gas
5
Q
Bred
A
- Implies that she’s pregnant
- has mated with a male
6
Q
Bred
A
- Implies that she’s pregnant
- has mated with a male
7
Q
Breed
A
- an animal descended from common ancestors
- common characteristics passed on to succeeding generations
8
Q
Bull
A
- intact male bovine
- usually fertile
9
Q
Bull
A
- intact male bovine
- usually fertile
10
Q
Calf
A
- male or female bovine
- in beef cows it’s under a year old (in dairy it’s around weaning)
11
Q
Calf crop percentage
A
The percent of cows bred that wean a calf
12
Q
Calving interval
A
- amount of time between the birth of one calf to the birth of the next calf (about 12 months)
13
Q
Colostrum
A
- milk secreted in the first few days after calving
- rich in nutrients and antibodies
- can be frozen for up to one year
- absorption window is gone by 24 hours (best before 6 hours)
- ideally receives 4L
14
Q
Crossbreeding
A
- mating of animals from different breeds
- introduces new genes
- offspring generally healthier and grow faster
- common in beef
15
Q
Culling
A
- removal of less productive and less desirable (behavior and physical problems) animals from the herd
- the calf in theory is genetically superior to the dam
16
Q
dystocia
A
- difficult labor
- causes: maternal problems (size miss match, c-section), fetal problems (wrong orientation)
17
Q
environmental effect
A
- total of all non-genetic influences that can affect the animal’s performance
- housing
- feed
- weather
- management practices
18
Q
feed conversion
A
- the amount of feed required to achieve one unit of gain (it’s about 6:1)
- depends on:
- genetics
- nutritional quality
- animal age (more efficient when young)
- gender (intact males are less efficient)
- Environment
19
Q
heifer
A
- female bovine that has never had a calf
- usually under 2 years
(dystocia is more common for heifers)
20
Q
lactation period
A
- length of time the mom is nursing the calf
- for beef is 200 days (5-7 months, may be earlier under stressful conditions)
21
Q
marbling
A
- dispersion of fat within muscle fibers (intramuscular fat)
- accounts for juiciness and taste
- genetic and environmental factors
22
Q
maternal effect
A
- the effect the dam has upon the weaning weight of the calf
- dependent on: milk quality, milk quantity
23
Q
open
A
not in calf (not pregnant)
24
Q
polled
A
- born without horns
- genetic
25
shrink
- loss in body weight when cattle move to slaughter
- is a result of: transport stress, inaccessibility to water
26
sire
male parent
27
spring heifer
- pregnant heifer
- in her last trimester of her initial pregnancy
28
stag
- improperly castrated male
- or castrated too late
- still show male characteristics
- lowest beef level
29
steer
castrated male
30
tag
- refers to the amount of manure caked around the rump and sides of the animal
- this is a packing industry problem when using the hides
31
veal
- meat from a calf (hide off carcass weight160kg)
- has to be less than 160-180kg
- about 5-6 months
- can either be red (grain-fed) or white (milk-fed)
- white is deficient in hemoglobin
32
what is red or white veal
red = grain-fed
white = milk-fed
33
wean
- removal of the option for the calf to nurse, followed by the removal of the calf from the dam
- in dairy weaning is almost immediate
- can be done by putting a fence between them (called a fence line)
- can put anti suckling device to decrease suckling (ring in the nose)
34
post-weaning lag
- calf has a lag in growth right after weaning
35
yield or dressing percentage
- what is left of the carcass after slaughter following the removal of hide, SQ fat, and organs
- in cattle, the goal is 55-60%
36
what is removed from the carcass after slaughter (the yield)
- hide
- SQ fat
- organs
