Under which Indian law does the Central Zoo Authority regulate zoos?
D. Wildlife (Protection) Act, 1972
The Central Zoo Authority was created under the Wildlife (Protection) Act 1972, which also governs capture and movement of wild animals. The PCA Act covers cruelty generally, the IVC Act covers the profession, and the Environment (Protection) Act covers pollution and waste.

Which post-mortem judgement fits a carcass with one localised, healed bruise on the hindquarter and no other abnormality?
B. Partial condemnation: trim the affected tissue and pass the remainder
A localised lesion in an otherwise normal carcass is trimmed and the rest passed. Total condemnation and heat treatment are for generalised or specified conditions, and returning carcasses for informal use is not a recognised judgement.

Which test is used to confirm that milk has been adequately pasteurised?
B. Alkaline phosphatase test
Alkaline phosphatase is destroyed by a heat treatment slightly greater than that needed to kill the target pathogens, so a negative result confirms adequate pasteurisation. Clot-on-boiling checks acidity, methylene blue reduction estimates bacterial load in raw milk, and CMT screens for mastitis.

At the reception dock, a sample of raw milk decolourises methylene blue in 30 minutes while most samples take several hours. What does this indicate?
D. A high bacterial load and poor hygienic quality
Bacteria use up oxygen and reduce the dye; the faster it decolourises, the greater the bacterial load. Fast reduction does not measure fat or added water, and sterile milk would keep its colour longest.

A broiler house sold 9,600 birds at an average 2.2 kg live weight, and the flock ate 36,960 kg of feed. Using total live weight sold, what is the feed conversion ratio?
D. 1.75
Live weight sold = 9,600 × 2.2 = 21,120 kg. FCR = 36,960 ÷ 21,120 = 1.75. 1.68 uses 10,000 birds placed instead of those sold, 0.57 inverts the ratio, and 3.85 divides feed by birds alone.

Where and when is Marek's disease vaccine given to commercial chicks?
A. At the hatchery, at day old or in ovo
Marek's vaccine must reach the chick before field exposure, so it is given by injection at day old or in ovo at the hatchery. Later water, eye-drop or feed routes are too late and are not used for this vaccine.

Which practice is correct when giving a live vaccine to broilers through drinking water?
A. Withdraw water briefly beforehand and use chlorine-free water with a milk powder stabiliser
Brief water withdrawal makes birds drink promptly; chlorine and disinfectants inactivate live vaccine, so water is chlorine-free and stabilised with skim milk powder. Vaccine is reconstituted just before use and the volume is set so it is drunk within a short period.

A broiler flock of 12,000 chicks placed had 420 deaths by the end of the cycle. What is the cumulative mortality?
C. 3.5%
Mortality = 420 ÷ 12,000 × 100 = 3.5%. 35% and 0.35% are decimal slips, and 96.5% is liveability, not mortality.

A buffalo died suddenly overnight; the owner reports dark, tarry blood oozing from the nostrils and anus, and the carcass shows no rigor mortis. What should the field intern do?
B. Not open the carcass; collect a peripheral blood smear and report suspected anthrax
Sudden death, unclotted blood from natural openings and absent rigor point to anthrax. The carcass is not opened, as air exposure leads to sporulation; a blood smear is taken and the case reported. Skinning or disposal in water spreads spores.

Under the Animal Birth Control Rules 2023 in India, what happens to a street dog after sterilisation and anti-rabies vaccination?
A. It is released back to the same area from which it was captured
The ABC Rules require dogs to be returned to the locality where they were caught, so a stable, vaccinated, sterilised population holds the territory. Relocation to shelters, forests or breeders is not the method.
