Question Title

1. Enter your First and Last Name

Question Title

2. Somatic Cell Count (SCC) is a measurement used to quantify somatic cells in milk.

True

False

Question Title

3. Compared to a healthy mammary gland, an infected mammary gland will:

produce more milk

have a lower somatic cell count

have increased permeability of the alveoli cell membranes

increase the fat content of milk

Question Title

4. Milk with a somatic cell count of 100,000 cells/ml has lower concentrations of lactose, casein, and fat compared to milk with a somatic cell count of 1,000,000 cells/ml.

True

False

Question Title

5. Milk from an infected mammary quarter will generally have a somatic cell count greater than ____ cells/ml.

100,000

750,000

200,000

1,000,000

Question Title

6. Somatic cells can pass from blood into milk due to the increased permeability of the alveoli cell membranes; this mechanism also allows leakage of other blood components into milk, changing milk composition.

True

False

Question Title

7. Select all that apply. The use of individual cow Somatic Cell Count is important to:

identify which cows/quarters are infected

estimate the loss of milk production

evaluate the severity and duration of infections

identify newly infected cows

Question Title

8. What cell population is greatly increased when the mammary gland is infected?

macrophage

neutrophil

epithelial

lymphocyte

Question Title

9. Select all that apply. The use of bulk tank Somatic Cell Count is important to:

classify the primary type of bacteria causing infections

monitor the prevalence of infection in the herd

determine if the herd infections are improving or worsening

estimate how many cows have clinical infections in the herd

Question Title

10. Fill in the blank. U.S. regulations state that both Grade A and Grade B bulk tank milk must have somatic cell counts lower than ______.

750,000

750

Question Title

11. The standard goal for the somatic cell count of bulk tank milk is less than _____ cells/ml.

100,000

500,000

200,000

50,000
