A

Calcium carbonate - pododermatitis

34
Q

Which toxin causes toxicity via inhibiting an neurotransmitter?

A

Strychnine (inhibits inhibitory GABA transmission)

35
Q

Which toxin causes toxicity via cell membrane damaage via ROS?

36
Q

41
Q

What are the five canine personality dimensions? SATEN

A 
Amicability
Training focus
Neurotic
Extraverted
Self assuredness/ motivated
42
Q

What is the accuracy of the study?

A

whether the relative risk you have come up with is the true relative risk of the population - can never really know

43
Q

What are the three types of descriptive study?

A

Case reports
Case series
Survey

44
Q

What are the three types of analytical epidemiological study?

A

Cohort
Case control
Cross sectional

45
Q

What is the power of a study?

A

The chance that you will see the effect through your study if the alternate hypothesis is true i.e how well can your study demonstrate the effect. Helps to have larger sample size.

46
Q

What is the precision?

A

Precise studies are free of random error - their results are fairly cohesive. The smaller your 95% Ci the more precise. Usually helps to have bigger sample size

47
Q

What is the 95% CI?

A

The 95% chance that the real population parameter falls within this range.

48
Q

Three types of bias?

A

Selection
Information
Confounding

49
Q

What are some feed options for supplementary feeding?

A 
Legumes (lupins, beans or peas) as high protein and high ME 
Lucerne hay or silage 
Silage of any grass
Hay + grain
Grains include wheat, barley and oats
50

A 
Chickens
Dairy cows
Beef cows

Q

What do molybdenum and selenium form with copper in the rumen to reduce it availability?

A

Thiomolybdate

53
Q

54
Q

What two factors of gilts does increased lean tissue growth affect?

A 
Leg strength (poor)
Ability to sustain lactation (unable)
55
Q

Complex carbohydrates includes?

A
