Five practice questions, worked

Original questions written to this exam's published syllabus and pattern. Not past papers.

1. Why do indoor-reared piglets need supplementary iron in the first days of life?

  1. Sow's colostrum contains an iron-chelating protein that blocks iron uptake in the piglet's gut
  2. Piglets lose most of their iron through the umbilical cord bleeding that follows farrowing
  3. Piglet haemoglobin cannot bind iron until the thymus matures at about three weeks of age
  4. They are born with small iron reserves, sow's milk is low in iron and they cannot root in soil
Answer and working

D. They are born with small iron reserves, sow's milk is low in iron and they cannot root in soil

Low birth reserves, low iron in sow's milk, very fast growth and no access to soil together make iron-deficiency anaemia predictable. Iron injection in the first days of life is the usual prevention.

2. The protein shell that encloses a viral genome, together with the genome itself, is called the:

  1. Nucleocapsid
  2. Envelope
  3. Peplomer
  4. Capsomer
Answer and working

A. Nucleocapsid

Genome plus capsid is the nucleocapsid. A capsomer is one of the morphological protein units that make up the capsid, so it is a part, not the whole; the envelope is the lipid membrane outside the nucleocapsid, and peplomers are the glycoprotein spikes in that envelope.

3. In India, Newcastle disease is also commonly known by which name?

  1. Ranikhet disease
  2. Gumboro disease
  3. Bacillary white diarrhoea
  4. Angara disease
Answer and working

A. Ranikhet disease

Newcastle disease is called Ranikhet disease in India. Gumboro disease is infectious bursal disease, Angara disease is hydropericardium syndrome, and bacillary white diarrhoea is pullorum disease.

4. What vaccination interval does NADCP use for FMD in cattle and buffalo?

  1. Once in a lifetime at four months of age, like brucellosis
  2. Every three years, matching the duration of FMD immunity
  3. Every six months, with each animal ear-tagged and registered
  4. Only during outbreaks, as ring vaccination within 10 km
Answer and working

C. Every six months, with each animal ear-tagged and registered

Inactivated FMD vaccines give short immunity, so NADCP vaccinates every six months, identifying each animal with an ear tag and recording it in a national database. Lifelong or three-yearly schedules apply to other diseases and vaccines.

5. India's 19th livestock census (2012) counted 512.05 million livestock and the 20th census (2019) counted 535.78 million. What was the percentage increase between the two censuses?

  1. 4.4%
  2. 4.6%
  3. 23.7%
  4. 46.3%
Answer and working

B. 4.6%

Increase = (535.78 − 512.05) / 512.05 × 100 = 23.73 / 512.05 × 100 = 4.6%. Dividing by the new figure (535.78) gives 4.4%, a wrong base; 23.7 is the absolute increase in millions, not a percentage; 46.3% misplaces the decimal.
