modify date of weaning each year to achieve a trade-off between optimising the body condition fo the dam at next mating and optimising calf live weight before weaning

Question 16

explained early weaning beef

Answer 16

Drenching and vax and moving to worm free pasture is too much management

150kg, is very large, usually weaned at 100kg

correct = doing bare minimum of giving extra supplements, compared to if it were older

Question 17

when is pasture providing the best growth rate

Answer 17

when its growing rapidly

Not

• flowering and seeding
• maximum DM content - as the energy is less accessible
• reaching maximal DM content per Ha

Answer 19

Supplementation

culling cows

Question 20

Answer 20

always look at metabolised energy first

Question 21

Compensatory growth is most likely to occur in growing steers grazing

Answer 21

High quality pasture after several months of feed restriction through the dry season

• as the weight goes up and down but overall up
• if constant supplementation = just mostly maintaining very little going up

Question 22

Answer 23

Ca and protein

Question 24

Soybean

Answer 24

high protein

Answer 25

it is a NSP (constructed polypeptide) = so it is not as accessible

Answer 37

polutry food:water = 1:2 | pigs 1:2.5/3.5

Question 38

Laying hens, which statement most correctly describes the relationship between temperature and dietary energy requirements?

Answer 38
