Question Title

* 1. Enter your First and Last Name

Question Title

* 2. Select all that apply. The purpose of pre-milking procedures is to:

decrease bacterial load in harvested milk

provide stimulation for milk letdown

examine cow milk for abnormalities

reduce risk of intramammary infection

reduce contamination of the milking machine

Question Title

* 3. Select all of the procedures that are essential for adequate pre-milking preparation of the cow.

forestrip teats

wash the whole udder

disinfect teats

apply intramammary treatment

dry teats

clean teats to remove organic material

Question Title

* 4. Select all that apply. When cleaning teats to remove organic material you should:

massage the teats for 2 minutes

check for any udder abnormalities that could be signs of intramammary infection

check for abnormal teat skin conditions

wet the udder

Question Title

* 5. Select all that apply. Disinfecting the teats before milking is important to:

reduce contamination of milker's hands, the milking machine, and cow teats by environmental pathogens

kill bacteria from the environment that might be present on the teat skin

aid in the stimulation process

lower the potential of new intramammary infections

maintain milk quality

Question Title

* 6. Select all of the ways in which bacteria can enter the teat sinus.

Bacteria may enter the teat sinus by physical movements resulting from pressure placed on the teat end as the cow moves.

During machine milking, bacteria may be propelled into the teat canal and cistern via milk droplet impacts against the teat end.

Between milkings, bacteria may multiply inside the teat canal and pass through it.

Bacteria can be pushed into the teat canal during an intramammary treatment.

Question Title

* 7. The use of gloves during milking is not necessary because milkers constantly wash their hands.

True

False

Question Title

* 8. The pre-dip should cover the entire teat skin surface.

True

30 seconds

3 minutes

90 seconds

3 seconds

Question Title

* 10. Select the best answer. What is the major benefit of forestripping?

improved milk quality

reduction of milking machine contamination

aids in the stimulation of the milk letdown process

early detection of clinical mastitis

Question Title

* 11. Select all that apply

germicidal wipes: one must be used in each cow

pre-dipping and drying teats: may reduce bacterial population on the teat skin by 75%

non-return dip cups: are preferred for full coverage of the teat skin
