Which description fits a firearm entry wound inflicted at close range?
D. Small inverted wound with an abrasion collar, singed hair and powder tattooing
At close range the entry wound shows the effects of flame, smoke and unburnt powder: singeing, blackening and tattooing, around a small inverted wound with an abrasion rim. A large everted wound is typical of an exit; a wide pellet scatter without burning points to a distant shotgun discharge.

A buffalo is found dead suddenly with dark unclotted blood oozing from the nostrils and anus and no rigor mortis. What should the veterinarian do first?
B. Examine a peripheral vein blood smear stained with polychrome methylene blue
These signs suggest anthrax, and opening the carcass lets the bacilli sporulate and contaminate the site. A smear from a peripheral vein, such as an ear vein, stained with polychrome methylene blue (the M'Fadyean reaction) is examined first. Certifying lightning without examination is both unsafe and dishonest.

A spear enters the left side of a bullock's chest and passes out through the right chest wall. How is this wound classified?
B. Perforating wound
A wound that enters a body cavity is penetrating; one that passes through and out the other side is perforating. A spear wound is a stab-type wound, so lacerated and incised are wrong classifications here.

Why is a vetero-legal post-mortem preferably carried out in good daylight?
C. Colour changes such as bruising and congestion are judged most accurately
Artificial light can distort colours, making bruises, congestion and jaundice harder to assess. Daylight is preferred by convention in medico-legal practice, but an examination at night is not automatically invalid, and urgent cases may require it.

Cattle in a South Asian village are killed by 'sui': small pointed spikes driven into the skin. What is the poison and the typical local lesion?
A. Abrin from Abrus precatorius seeds; oedema and necrosis around a puncture
Sui are made from crushed seeds of Abrus precatorius, whose toxalbumin abrin causes marked oedema and necrosis around the puncture, followed by systemic illness. Ricin is a related toxalbumin from castor seed but is usually ingested, not inserted as sui.

A food inspector suspects that cooked sausages labelled as mutton contain beef. Which method is the most reliable for identifying the species?
A. PCR targeting species-specific mitochondrial DNA sequences
DNA survives cooking far better than proteins, and mitochondrial genes such as cytochrome b give species-specific results. Precipitin tests depend on native proteins that heat denatures, so they work poorly on cooked products. Fat colour and melting point are only supporting signs.

A bullock has six permanent incisors in wear and two deciduous corner incisors. What is its approximate age by the usual textbook guide?
B. About 3 to 3.5 years
Cattle replace incisors in pairs from the centre: roughly 1.5-2 years for two permanent teeth, 2.5-3 for four, 3-3.5 for six and 3.5-4 years for a full mouth. Ages vary with breed and nutrition, so any certificate should give a range.

What is 'bishoping' in the horse trade?
C. Cutting and burning false cups into incisors to make a horse look younger
Bishoping imitates the cups of a younger horse's incisors by cutting and staining or burning the tables. Horn filing is a separate fraud in cattle, and placing ginger in the anus is 'gingering'.

What is 'gingering' in the horse trade?
A. Placing an irritant such as ginger in the anus to raise tail carriage at sale
Gingering irritates the anus so the horse carries its tail high and appears lively. Nicking the tail muscles is a surgical way of achieving the same appearance. Both are frauds that misrepresent the animal's natural carriage.

A dealer leaves a buffalo unmilked for a day before market so that her udder appears large. How can a veterinarian detect this 'overstocking'?
A. By milking out completely and checking yield at the next regular milking
An over-full udder from missed milking looks impressive but the true yield is revealed by milking out and recording the next regular milking. Teat number and dentition are unaffected. Oxytocin may also be used to force a large let-down at the sale.
