A

it increases the palatability (juiciness/flavor/tenderness) of the meat and it also causes the fat to turn white.

Q

a producer has cattle that she knows produce calves with high carcass quality (80% choice and yield grade 2). she has been selling the calves at weaning. what marketing option should she used to insure she is paid for the high carcass quality of her calves?

what is a working chute used for?
vaccines, spraying, applying pour on insecticides
26
only about ____ of carcass is steak
25%
27
what do you look at to see maturity?
thoracic ossification and marbling. look between 12 and 13 rib for marbling
28
what does the USDA yield grade estimate?
how much lean is in the carcass
29
what are the factors that influence yield grade?
- adjusted fat thickness - hot carcass weight - kidney, pelvic, and heart fat - ribeye area (12th and 13th rib)
30
what USDA yield grades do we prefer?
2 or 3
31
how big should ribeye be?
12-14 square inches
32
where does the bright cherry red color come from?
myoglobin reacting with O2
33
what is the most limiting nutrient?
energy
34
protein requirements depend on
- body weight - milk production - growth - pregnancy
35
what is relative feed value?
ADF and NDF into single measure widely used for alfalfa
36
RFQ (relative forage quality)
greater than 140 - premium dairy cow 110-139 - good - lactating beef cow 90-109 - fair - dry cows less than 90 - utility
37
what can increase stocking rate by 10-20%?
multispecies grazing
38
why supplement?
improve animal performance facilitate handling
39
what should be available to cattle at all times?
salt blocks/mineral blocks
40
salt requirement
0.1 lb salt/100 lb body weight
41
advantages of creep feeding
weaning weight increase price of calves higher relative to feed costs useful for calves with skeletal frame and growth potential less stress at weaning time useful during drought to reduce calf forage consumption
42
disadvantages of creep feeding
cost of added weight is usually higher than return not recommended for replacement heifers because it impairs future milk production market price may be less for calves which are too fat
43
what is creep grazing?
calves have access to higher quality forage
44
what is the goal of stockers?
low cost gain
45
diets depend on
age, weight, sex raised vs purchased feeds relative cost of available feeds length of feeding time
46
common roughages
silage, hay, corn cobs
47
common concentrates
corn
48
what do implants do?
improve feed efficiency and average daily gain androgen implants also enhance muscle growth
49
finishing phase implants reduce
marbling score by 28 points % grading choice or higher by 10 points
50
common feed additives (antibiotics)
tylan - prevent liver abscesses chlotetracycline and oxytetracycline - treat respiratory disease
51
what does MGA do?
inhibits estrus in heifers
52
stocker gain goal
1.5lb/day or higher
53
what is one of the most important nutrient management practices for calves?
adequate colostrum intake
54
when to supplement protein?
every 5-7 days

67
hay feeding losses
hay ring - 4-6% loss trailer or cradle - 11-14% loss ground - 45% loss
68
storages losses
