1

Name the 4 growth promoter (GP) types

-antibiotic gp
-hormonal gp
-beta adrenergic ag.
-alternatives to ab gp

2

Which types of antibiotic gps are there

-ribosome function inhibitors
-cell wall inhibitors
-cation disruptors

3

Name some ribosomal function inhib.

-Avilamycin
-Tylosin
-Oleandomycin

4

Name the cell wall inhib

-bacitracin
-bambermycin

5

Name some cation disrupters

-Lasalocid
-Monensin
-Narasin

6

What effects do gps have

-metabolic effects
-nutritional effects
-disease control effects

7

How can a metabolic effect be achieved

a lot of energy is lost due to micr. fermentation in the gut of the animal - controlling the microbiome of the animal can help divert the lost energy to growth

8

How could a nutritional effect be achieved

inhibiting the cytokine release which have a catabolic effect and would thus lead to decr. in muscle mass

9

Name some imp. diseases which could be prevented to help the growth of animals

-necr. enteritis -poultry
-clostr. enteritis -SU
-prol. enter. - SU
-Dysent - SU
-Liver abscesses - feedlot cattle
-protozoal inf.


10

Name the four types of bb most commonly associated with resistance

-Salmonella
-Campylobacter
-E.coli
-Enterococci

11

The farming culture is the largest user of ABs there is T/F

f - 2nd

12

Which species does avialmycin have positive growth rate and fce effect in

broilers and pigs

13

What does Kitamycin improve in which species

-average daily weight gain in pigs

14

Name the species Oleandomycin effects

-fattening lambs
-suckling lambs
-pigs
-chickens

15

Which cell wall inhib. controls prol. enteritis in pgs and necr. enteritis in poultry and incr. weight gain in RU

Bacitracin

16

Name the benefits ruminants get from using ionophores

-mod. of microbial pop. - allows for incr. protein, energy and lipid availability due to incr. prod. of propionic acid
decr. lactic acid fermentation, decr. prot. degrad.

17

Name the hormonal Gp

-anabolics
-somatotropin

18

Name the anabolics

natural
-oestradiol
-progesterone
-testosterone
synth.
-trenbolone acetate
-zeranol
-melengestrol acetate

19

what is the effect of anabolic treated animals

-gain weight more rapidly and prod. leaner and better quality meat

20

What is a synonym for bovine somatotrophin

bovine growth hormone

21

Where is bovine somatorophin prod.

pituitary gland

22

How does bovine somatotrophin act

-mobilises body fat as use as energy and diverts feed energy towards milk prod. - incr. in milk prod 10-15%

23

Where are beta adrenergic rec being bound

-cardiac and smooth muscle

24

How do the beta adrenergic agonists act a s GP

at doeses several times higher than therapeutic doses they induce muscular hypertrophy

25

Name the beta adren. ag. used as feed additive

Ractopamine

26

Name some alternatives for AB GP

-probiotics
-oligosaccharides
-organic acids
-enzymes

27

How could probiotics help against path BB

by competitive exclusion of path. strains

28

How can Oligosaccharides (prebiotics) help

as a better energy substrate for the good BB

29

What's the effect of sodium butyrate

-reduces GI infl.

30

How could a non-ab rumen modifier help

in RU - Buffers reduce digestive dysfunction when diets high in grain or low in fibers are fed
