1

3 different types of activities of poultry industry

• Genetics/Selection farms (Primary Breeders)

• Reproduction Farms (Breeders + Hatchery)

• Production Farms

2

T/F broiler production is an "all in all out" system

true

3

at what age do boiler chickens go to harvest

6-7 weeks

4

feeding costs

2/3 total operation cost

5

energy sources

grains, grain by-products, animal and vegetable fats

6

T/F poultry have a limited ability to digest fiber

true

7

grains

50-80% of total ration

corn most commonly used

8

how are chickens fed

ad libitum

will eat to meet their energy needs

9

T/F high energy rations--> higher efficiency

true

10

what is the most important cereal

corn

11

oats and barely

cannot totally replace corn

limit incorporation to 10-15%

12

fats

used to increase energy levels in diet

nor more than 5-10%

13

what supplies essential AA

proteins

14

protein sources

• Soybean meal

• Canola meal

• Blood meal and Fish meal

15

mineral important for laying hens

calcium

16

sources of minerals

oyster shell and/or limestone

17

vitamins and mineral are normally supplied in what form

premixes included in pelleted diets

18

what are minerals needed for

formation of the egg shell

19

why use pellets

• Pelleted feeds have more nutrients per volume of feed

• Allow the use of ground material more efficiently -->no need for grit

20

T/F young animals can be fed pellets

false

21

forms of commercial manufactured feeds

• Mash

• Pellets

• Crumble

22

which poultry industry is phase feeding particularly important

laying hens

23

starter ration for weeks 0-6 form

mash

24

at what age do you start a growing ration

6 weeks

25

weeks 6-20

slowly shift from mash to pellet

protein decreases

26

factor effecting feed consumption in laying hens

• Egg production and size

• Body size

• Health status

• Temperature

27

phases of broiler feeding

• Starter

• Grower

• Finisher

28

important changes in broiler phases

• Protein Content

• AA content

• Feed structure

29

what does feed conversion depend on

• Genetic background of strain

• Type of feed used

• Temperature

• Feed waste

• Additives used in the Feed

• Management

30

differences in feeding turkeys

• Protein levels (higher)

• Vitamin composition

31

true

32

T/F turkey poults get stressed easily

true

33

how are 8-10 week old poults raised

confinement or range-based

34

as turkeys become older

• Energy levels increase

• Protein levels decrease

35

T/F Toms are grown to a later age than females

true

36

toms have higer_______requirements

protein
