Peak milk yield occurs at _____ weeks post-calving

8 weeks

2

Fatty Liver Syndrome has peak incidence from

_______ weeks post-partum

2 - 10 weeks

3

This syndrome is primarily seen in DAIRY cows

overfed during latter lactation or in those with a

long dry period

Fatty Liver Syndrome

4

What are the clinical signs seen in Fatty Liver Syndrome?

HIGH incidence of POST PARTUM disease

often accompanied by LEUKOPENIA

 

(often also have other issues like retained placenta or metritis)

5

How is Fatty Liver Syndrome treated?

50% glucose IV or 25% glucose/25% fructose IV

Protamine Zinc Insulin + Glucose

Choline + Niacin

PROPYLENE GLYCOL or SODIUM PROPRIONATE

ABx (for 2ndary infx)

6

______ ketosis occurs due to negative energy balance,

especially early in lactation

Primary

7

Secondary ketosis is related to ______, secondary to another dz

anorexia

8

Which form of ketosis is most likely to be seen?

Secondary ketosis

9

The nervous form of this condition in lactating cows occasionally occurs,

causing the cows to self-mutilate. Rabies is always a DDx for this.

Ketosis

10

What clinical signs do you expect to see with ketosis?

decreased appetite and milk production

some degree of hypocalcemia

odor of ketones on breath, urine, and in milk

11

What tests are used to diagnose ketosis?

Powder or Dipstick test

12

Ketones are more concentrated in _____ than in milk

urine

13

What drugs are used to stimulate gluconeogenesis in the treatment

of bovine ketosis

Dexamethasone/Flumethasone

or

Bovine Somatotropin

14

What is the best treatment for bovine ketosis?

500 cc of 50% glucose RAPID IV

15

The cow utilizes _______% of the glucose its given

when treating ketosis with 500 cc of 50% glucose rapid IV

80%

16

How do you prevent bovine ketosis?

Maintain proper BCS (3.5/5) from the dry period through calving

17

Pregnancy toxemia occurs more frequently in _______ cows and small ruminants

BEEF

18

Parturient paresis is also known as

milk fever

19

Which cow breeds are predisposed to milk fever?

Jersey and Guernsey

20

What calcium level do you expect to see in a Downer Cow?

7.5 mg/dL

21

What is the normal calcium level in a cow?

9 - 12 mg/dL

22

What happens if a non-lactating cow is fed a high calcium diet?

Parathyroid gland slows down and stops producing PTH,

resulting in decreased calcium mobilization

23

T/F:

Milk fever can be the basis for abomasal displacement, metritis, mastitis,

or anything that has to do with failure of muscle movement of internal organs

TRUE

24

You see a DOWN COW with COLD EARS.

What is your primary ddx?

Parturient Paresis (Milk Fever)

25

Stage _____ of Milk Fever happens very quickly and is often not seen.

It includes hypersensitivity, excitement, twitching, and incoordination

Stage 

26

A cow in sternal recumbency with head to the side, and signs related to 

lack of muscular activity (failure of defecation or urination, slightly bloated),

subnormal temperature and dilated pupils is in

this stage of MILK FEVER

Stage 2

27

In this stage of Milk Fever,

all muscles are flaccid, and cow is unable to remain in sternal recumbency,

so it falls into lateral recumbency.

It runs the risk of aspirating and dying

Stage 3

28

How is milk fever treated?

IV Calcium Borogluconate

29

T/F:

One sign you may see in cows with milk fever is lack of a PLR

TRUE

30

What is the first sign you see after treating a cow with milk fever

with IV Calcium Borogluconate to know your tx is working?

Muscle fasciculations
