UNDERSTANDING - 10 - AOC_Teatcup Action Survey

Question Title

2. The teatcup liner is one of two milking machine components that come into contact with cows.

True

False

Question Title

3. During milking, there are interactions between the liner and the teat that are:

political and correct

physiological and physical

psychological and metaphysical

positively and negatively charged

Question Title

4. The selection of the internal diameter of the liner is most often based on:

the smallest cow’s teat diameter

the largest cow’s teat diameter

what will stay on the cows without squawks and drop-offs

the average diameter of the full teats

Question Title

5. Select all of the forces that affect the depth a teat moves into a liner shortly after machine attachment.

liner/teat friction

gravity

liner vacuum

pulsation rate

Question Title

6. Pulsation occurs when air pressure in the space between the shell and the liner is varied between atmospheric pressure and liner vacuum in a cyclic manner.

True

False

Question Title

7. Because milk is removed from the teat by compressive force, the distance the teat enters the liner does not affect the efficiency of milking.

True

False

Question Title

8. When the liner is closed during pulsation, the vacuum is cut off to the teat end, thus preventing congestion and edema.

True

False

Question Title

9. When the teat empties during milking, the liner moves up on the teat indicating that:

the claw weight is too low

the peak milk flow rate period has ended

machine stripping is occurring

the system vacuum level should be lowered

Question Title

10. The main purpose of pulsation is to limit the development of teat tissue congestion and edemas during milking.

True

False

Question Title

11. Pulsation helps to:

protect the medial suspensory ligament from damage

restrain milk flow

reduce the possible discomforts of milking

increase the occurrence of new mastitis infections

Question Title

12. It is perfectly normal and desired for a cow’s milk flow graph to register a short flow followed by little to no flow, then a quick advance to peak flow.

True

False

Question Title

13. Milk flows from the teat during milking due to the compressive load of the liner applied to the teat.

True

False

Question Title

14. Average liner compression can be determined, within a pulsation cycle, by measuring the vacuum level in the teatcup pulsation chamber when:

milk stops flowing

milk either starts or stops flowing

the midpoint of milk flow is reached

milk starts flowing

Question Title

15. Teat-end hyperkeratosis is a thickening of the skin that lines the teat canal and surrounds the external teat orifice.

True

False

Question Title

16. Hyperkeratosis can be reduced by:

increasing claw capacity

changing liners

adjusting the threshold settings of the detachers

applying a good salve

Question Title

17. The main variation in flow rate between cows is due to:

milking equipment design

teat canal size

pulsation rate

detacher settings

Question Title

18. Pre-stimulation typically results in:

more milk and less machine on-time

less milk and longer machine on-time

no effect on flow rate or machine on-time

lower strip yields

Question Title

19. The low-flow rate period of milking begins when the milk flow pathway from at least one quarter becomes restricted.

True

False

Question Title

20. What machine factor has more to do with milking characteristics than any other?

pulsation ratio

pulsation rate

liner design

milk line vacuum level

Question Title

21. Machine-induced teat congestion is exacerbated by modern narrow-bore inflations with soft mouthpiece lips.

True

False
