Flashcards in Metabolic Disease In Dairy Deck (24):
1

Hypocalcemia

Milk fever (Small animal; parturient paresis)

2

Who is at a higher risk for milk fever?

Older cows with more than one calf, 6th or greater lactation, Jersey, at the end of grazing season

3

Signs of milk fever.

Incoordination, loss of appetite, lethargy, muscle tremors, teeth grinding, down cow

4

Clinical signs of milk fever.

S CURVE of spine, low body temperature, cold extremities (ears), wobbly, decreased defecation

5

Complications of milk fever

Gassy bloat, prolapse of uterus, muscle damage

6

What is the sub clinical manifestation (waterfall effect) of milk fever?

Retained placenta, metritis, DA, ketsosis

7

Treatment steps for milk fever.

Calcium gluconate IV 23%, caldex #2, oral calcium drench, Cal-Mag gel

8

Do not confuse milk fever with..

Toxic mastitis

9

Occurs when high producing cows can't eat enough (or feed doesn't have enough) carbs to satisfy glucose needs. - usually high producing cows

Primary ketosis

10

Occurs when a primary disease causes and upset of digestion and absorption of carbs.

Secondary ketosis

11

Initial then Constant decline in appetite. Will not eat grain and eats random object. Eventfully the body will correct itself due to dropping milk production.

Wasting ketosis

12

Where can you detect ketones?

Breath smell, urine, milk, cow manure becomes hard and dry

13

Least common form of ketosis - causing range of blindness, wandering, licking metal

Nervous ketosis

14

How do you treat ketosis?

IV dextrose, cal dex #2, B vitamins (increase appetite), oral propylene glycol (high calories), corticosteroids

15

Most common DA .

Left DA

16

80% of LDA occur when?

Within the first month of lactation

17

Signs of a DA

Off feed (hay but no grain), ketosis, "ping" (over l/r paralumbar fossa)

18

More likely to be a torsion abomasum.

Right DA

19

Signs of a RDA.

Abdominal pain, no eating or drinking, right side distention, ping on the right side, can be palpated

20

Treatment of DA.

Cull, wait and see, surgery, roll and tack, RDA - emergency surgery

21

Predisposed from feeding errors that encourages cows to become excessively conditioned during late lactation or dry period.

Fat cow syndrome

22

Morbidity of 50-90% and mortality of 25%

Fat cow syndrome

23

Signs of fat cow syndrome.

Fat cows in a dry herd, skinny cows in a fresh herd, increased incidences of metabolic diseases

24

When does metabolic transition start and end?

Three weeks before calving, and 30 days after calving
