Q

How does muscle scoring work?

A

More heavily muscled goat has higher dressing percentages and higher retail goat meat yields, both of which are drivers of profitability. It is therefore desirable to select for increased muscling.

Q

How do you muscle score a goat in the long ribs?

A

Feel over the area where the GR measurement would be taken on the carcase (that is 110 mm from the backline along the second last long rib) for the amount of tissue over the ribs and ease with which individual ribs can be felt. Fingers should be moved through the fibre to get onto the skin. Use tips or balls of fingers.

Q

How do you muscle score a goat in the end of short loin ribs?

A

A good indication of musculature and fat cover can be obtained by placing the thumb on the top of the backbone and fingers over the ends of the short loin ribs. Move hands back and forth along the spine, feeling the amount of tissue over the backbone and ends of the short ribs. Note also the ease with which individual bones can be felt.

Q

How do you muscle score a goat in the top of the backbone?

A

The area to be felt is the top of the backbone in the long rib and short loin areas. It can be felt with the thumb at the same time as the fingers are feeling the long ribs and ends of the short loin ribs.

Q

How do you muscle score a goat in the eye muscle?

A

The shape of the eye muscle is felt in the short loin area. It can be felt with the thumb or fingers at the same time the ends of the short loin ribs and the top of the backbone are being assessed.

Q

What is footparing?

A

Footparing is cleaning the foot and is important because a sheep’s feet are constantly growing and can become split and painful if not checked and pared regularly.

17
Q

What is the 1st process of footparing?

A

Restrain the sheep in a sitting position with back against your legs. If you leant them against your legs, this ensures that both your hands are free.

18
Q

What is the 2nd process of footparing?

A

Lift up one of the sheep’s feet.

19
Q

What is the 3rd process of footparing?

A

Using the tip if the scissors clean any mud that is caked into the hoof and check in between toes for any signs of infection.

20
Q

What is the 4th process of footparing?

A

Cut the tip of the hoof at the heel and then, cutting away from you, cut the foot even with the heel.

21
Q

What do you need to remember when you carry clippers?

A

Never carry the hoof clippers while you’re restraining the sheep. Have a second person hand them to you. Otherwise you’re putting yourself and/or the sheep at risk of injuries.

22
Q

What environment is ideal for foot problems?

A

Sheep and goats that are kept in damp, muddy environments and do not have their feet trimmed regularly are very prone to foot problems, such as footrot and foot scald. Animals that have excessive hoof growth are also very susceptible to laminitis, joint/ tendon problems, and arthritis.

23
Q

What is weighing?

A

The measurement of body weights.

24
Q

What is the best weighting method?

A

Live-weight scales allow easy and accurate measurement of the body weights of goats.

25
Q

What can live-weights be used for?

A
  • estimate carcase characteristics for goat meat
  • marketing
  • select faster growing goats
  • monitor general flock progress and performance
  • determine dose rates for drenches and some dips
  • estimate feed requirements accurately for drought
  • lot feeding.
26
Q

What is marking?

A

To tag an animal for identification.

27
Q

How do you mark?

A

Ear tags, tattooing or micro-chipping.

28
Q

What causes Johne’s disease?

A

Mycobacterium Para-tuberculosis

29
Q

How does Johne’s disease spread?

A

Spread by faeces. The animal that eats from contaminated pasture and/or drinks contaminated water will get the disease.

30
Q

What are symptoms for Johne’s disease?

A

Weight loss, chronic diarrhoea, wasting, significant mortality, reduced productivity, abnormally weak/thin.

31
Q

What are preventative measures for Johne’s disease?

A

Minimise risk of bringing it onto the property by checking the chance of contamination of animals you are buying. Get a Goat Health Statement.

32
Q

What impact does Johne’s disease have on the farm productivity and profitability?

A

Due to the disease the farmer must cull the infected animals, to prevent it from spreading. During this time there are less animals and therefore less productivity and the farmer may go into debt as they do not make as much profit.

33
Q

What is the gestation period for goats?

A

150-153 days

34
Q

What cycles do does have?

A

In the wild they are seasonally polyoestrus, however, farmed goats tend to cycle throughout the year
