What this subject covers

The hands-on, non-credit farm course: handling, milking, feeding, identifying and recording animals, and routine procedures such as hoof trimming, dehorning and castration.

In the exams: Practical skills examined in OSCE-style licensing exams (RCVS SME OSCE, AVE clinical exam)

What SAVC Registration Examination asks from it

10 practice questions, worked

Choose an answer, then open the working. Each explanation says why the right answer is right and why the others are not.

1 · Identification: tagging and tattooing · medium

A ewe has six permanent incisors and two temporary corner incisors. Which age range best fits?

  1. Under one year, still a lamb with milk teeth
  2. About two and a half to three years
  3. Five years or more, judged broken-mouthed
  4. About one to one and a half years, a yearling
Answer and working

B. About two and a half to three years

In sheep the centrals erupt at about 1 to 1.5 years, the medials at about 1.5 to 2, the laterals at about 2.5 to 3 and the corners at about 3 to 4 years. A six-tooth ewe is therefore about 2.5 to 3 years old.

2 · Milking · easy

A cow is milked at 06:00 and 16:00 each day. What are the milking intervals?

  1. 8 h and 16 h
  2. 12 h and 12 h
  3. 10 h and 14 h
  4. 6 h and 18 h
Answer and working

C. 10 h and 14 h

From 06:00 to 16:00 is 10 hours; from 16:00 to 06:00 is 14 hours. Equal intervals (12:12) give slightly higher yields and less udder pressure, so farms aim for intervals as near equal as possible.

3 · Milking · hard

A parlour shows rising rates of rough, hyperkeratotic teat ends and new mastitis cases. Which check comes first?

  1. A dynamic test of vacuum, pulsation and liner condition
  2. Extra fore-stripping to collect milk for fat analysis
  3. A switch from full-hand milking to stripping throughout
  4. A change to a higher-protein concentrate for the whole herd
Answer and working

A. A dynamic test of vacuum, pulsation and liner condition

Teat-end damage and new infections often follow faulty vacuum level, pulsation or worn liners. Machines are tested at least yearly and whenever teat condition worsens; liners are changed on schedule.

4 · Daily farm routines · hard

Which practice best reduces the selection of anthelmintic resistance in a seasonal deworming routine?

  1. Using faecal egg counts to decide when and which animals to treat
  2. Rotating to a new drug class at every treatment regardless of results
  3. Under-dosing by estimating weights by eye to save drug costs
  4. Deworming all animals monthly throughout the year as a fixed rule
Answer and working

A. Using faecal egg counts to decide when and which animals to treat

Targeted treatment guided by faecal egg counts reduces unnecessary treatments; frequent blanket treatment and under-dosing select resistant worms. Rapid rotation of classes is not a substitute for monitoring.

5 · Hoof trimming · easy

In the hind feet of a dairy cow, which claw carries more weight and more often develops sole ulcers?

  1. The two dew claws at the back
  2. The medial (inner) claw
  3. Both claws equally, as in front feet
  4. The lateral (outer) claw
Answer and working

D. The lateral (outer) claw

In the hind limbs the lateral claw bears more weight, overgrows more and is the usual site of sole ulcers. In the front limbs the medial claw is larger.

6 · Hoof trimming · medium

During trimming, a beginner pares the sole until it flexes under thumb pressure. What is the problem?

  1. The sole is now ideal and needs no further attention
  2. The heel is too high and should be lowered at once
  3. The claw needs to be shortened further to compensate
  4. The sole is now too thin and the cow will be sore
Answer and working

D. The sole is now too thin and the cow will be sore

A sole that yields to thumb pressure has been over-trimmed; a firm thickness of about 5-7 mm is left. Over-trimming causes lameness and new lesions.

7 · Castration methods · hard

How is an emasculator oriented on the spermatic cord?

  1. Placed across the scrotal skin, before the scrotum is opened
  2. Crushing jaw on the body side, with the cutting blade towards the testis
  3. Both jaws on the testis side, so the cord stump is left long
  4. Cutting blade on the body side, crushing jaw towards the testis
Answer and working

B. Crushing jaw on the body side, with the cutting blade towards the testis

The crush must be on the body side of the cut, so the cord stump left in the animal is crushed and does not bleed. In horses this is remembered as 'nut to nut', the wing nut facing the testis.

8 · Castration methods · hard

When the closed bloodless method is used to castrate a calf with an emasculatome, how is it applied?

  1. The scrotum is opened and the cords are crushed under direct view
  2. Each spermatic cord is crushed separately through the intact skin
  3. A rubber ring is applied first and then crushed with the tool
  4. Both cords and the whole scrotal width are crushed in one bite
Answer and working

B. Each spermatic cord is crushed separately through the intact skin

Each cord is crushed separately, at slightly different levels, without crushing the full width of the scrotum, so the scrotal blood supply is kept and the skin does not slough. The skin is not opened in this method.

9 · Castration methods · medium

Why is a scrotal or inguinal hernia a problem when castrating a piglet?

  1. It may make the testes too small to remove by any method
  2. It causes immediate tetanus whenever a rubber ring is used
  3. It doubles the boar taint in the meat of that piglet later
  4. Cutting into it can let intestines out through the incision
Answer and working

D. Cutting into it can let intestines out through the incision

In a herniated piglet the intestine lies in the scrotum or inguinal canal; an open castration can lead to evisceration. These piglets need a technique that closes the hernia, or are not castrated.

10 · Castration methods · hard

A steer castrated with an open method several weeks ago has a firm, swollen, discharging cord stump. What is the most likely diagnosis?

  1. Scirrhous cord
  2. Cryptorchidism
  3. Hydrocele
  4. Orchitis
Answer and working

A. Scirrhous cord

Scirrhous cord is chronic infection of the spermatic cord stump after castration, with a firm swelling and often a discharging tract. Orchitis needs a testis; cryptorchidism is a retained testis; hydrocele is fluid in the vaginal tunic.
