UNDERSTANDING - 10 - AOC_Liner Compression

Question Title

1. Enter your first and last name

Question Title

2. Select all that are true. Liner compression:

Is the force that the liner applies to the teat when the liner is fully closed.

Is responsible fore relieving teat end congestion that develops during the b-phase of pulsation.

Is caused by the vacuum difference across the liner in the d-phase.

Occurs when the vacuum across the liner at the "touch point" applies strong compression to the teat end.

Question Title

3. Select all that match the following.

Average claw vacuum: inside the liner

pulsation chamber vacuum: outside the liner

atmosphere or zero vacuum: outside the liner in the d-phase

average claw vacuum during the d-phase: vacuum difference across the liner

Question Title

4. The residual vacuum for massage equals

claw vacuum - touch point

claw vacuum + touch point

Question Title

5. The point at which milk flow just starts or stops is a much more accurate estimate of liner compression and gives a relative measure of compression for liners of any shape or material.

True

False

Question Title

6. Liner compression as measured using the start of milk flow measurement of about ___ kPa appears to be sufficient to relieve teat congestion for moderate teat end vacuum (38-40 kPa).

Question Title

7. Select the correct sequence of events.

more hyperkeratosis -> higher claw vacuum -> higher liner compression

higher claw vacuum -> higher liner compression -> more hyperkeratosis

higher claw vacuum -> more hyperkeratosis -> higher liner compression

higher liner compression -> higher claw vacuum -> more hyperkeratosis
