Answer 1

adapt cattle to diet while building water and DMI
adapt cattle to environment
adapt cattle to new cohort

Answer 2

controlled/programmed growth
optimize feed efficiency
support immune responsiveness

Question 3

goals of finishing nutrition (4)

Answer 3

manage digestive upset
maximize G:F
target carcass composition
support immune responsiveness

Question 4

preweaning factors of BRD

Answer 4

prenatal nutrition
colostrum intake
BVD
preshipment management

Question 5

postweaning factors of BRD

Answer 5

transport stress
commingling
receiving management
receiving nutrition

Question 6

most important factor to consider when transitioning

Answer 6

process should be quiet and slow in all aspects

Question 7

newly received calves are subjected to (5)

Answer 7

physiological and psychological stress
physical exhaustion
immune system suppression
viral and bacterial respiratory pathogens
water and feed deprivation

Question 8

3 primary immediate needs of incoming calves

Answer 8

water
feed
rest- have pens ready before animals arrive

Question 9

impacts of stress on new calves (3)

Answer 9

reduced appetite
poor immune response
increase morbidity and mortality

Question 10

goal for DMI %

Answer 10

2.5-3% of bodyweight

Question 11

hay on arrival

Answer 11

should be immediately available as either free choice or in the bunk
can be fed in addition to starter diet
should only continue if animals refuse to eat starter

Question 12

feeding hay for too long

Answer 12

reduces performance overall

Question 13

forage to concentrate on receiving diet

Answer 13

70:30

Question 14

on arrival hay should be placed close to water, why?

Answer 14

teach calves where the water is
get calves to drink water

Question 15

when should intake expect to increase

Answer 15

2-4 days

Question 16

what is worse: low intake or low gain

Answer 16

low intake bc it increases risk of illness
initial low gain can be solved later with diet formation

Question 17

DM CP target

Answer 17

14%

Question 18

DM urea target

Answer 18

<0.35%

Question 19

too high protein consequence

Answer 19

costly energy wise
exacerbate stress

Question 20

K % DMI in diet

Answer 20

1.2 - 1.4 %

Question 21

importance of K in diet

Answer 21

critical electrolyte that is lost in responce to dehydration

Question 22

copper ppm in diet

Answer 22

10-15

Question 23

zinc ppm in diet

Answer 23

75-100

Question 24

___ and ____ have increased excretion during stress

Answer 24

copper and zinc

Question 25

first ___ days is the greatest concern for health of incoming cattle

Answer 25

45

Question 26

cattle risk categories

Answer 26

high: low BW, long transport, sent right after weaning medium low: pre weaned, pre conditioned, increased BW, shorter transport

Question 27

how feed restriction impacts DMI

Answer 27

longer feed restriction (time off feed during transport) results in longer time required to get back to normal DMI

Question 28

eating less and bloat risk

Answer 28

eating less means less adapted to VFA production and increased bloat risk when reintroduced to full diet volume

Question 29

inclusion of hay in beginning impact on ADG

Answer 29

ADG increased weeks 1-3 when hay is included in the diet (especially when mixed with TMR) but should be taken away at week 4 as ADG goes down

Question 30

BHV and DMi

Answer 30

BHV results in 30-75% reduction in DMI compared to pre challenge levels

Question 31

how are yearlings different from weaned calves

Answer 31

not likely to stress less risk of BRD start to eat easier often more aggressive at the feed bunk can move up to starter diet faster

Question 32

preconditioning (4)

Answer 32

vaccination 3wk prior to marketing and calves are at least 4 months old castrated/dehorned if necessary treated for parasites weaned (45d min) and have experience eating from bunk

Question 33

outcomes of preconditioning

Answer 33

improved rates of gain reduces treatment
