New Zealand White rabbit care in India: weight, feet and heat

Despite its name, ARBA says the New Zealand was developed in the United States and recognised in 1916. PetMD places its development in California in the early 1900s and says nobody is sure where the name came from. The first New Zealands were red; after a red doe produced white kits in 1917, white became the preferred colour.

ARBA says the breed was prized for its quick growth and meat, and that white pelts, which were easier to dye, let the White take over the fur market. ARBA today recognises five colours: red, black, blue, white and broken.

The White also became a research animal. The Canadian Council on Animal Care's guide names it the most widely used breed in Canadian laboratories, for its medium size, very docile nature and large unpigmented ears.

The New Zealand White is one of the rabbit breeds Indian agricultural institutions describe for meat and fur. Kerala Agricultural University lists it with the Soviet Chinchilla, Grey Giant and White Giant, giving an adult weight of 4.5 to 5 kg, though it describes the breed as developed in England, unlike ARBA. A Kerala study published in 2000 kept it as a temperate breed in the humid tropics and found it had the lowest pre-weaning mortality of the three breeds compared.

India's rabbit population was about 406,000 according to an ICAR review, spread across 27 states and kept mainly for meat and Angora wool. No source we found gives a date for the breed's first import. Kept as a pet, the farm breed's fast growth means its weight and flooring need watching.

PetMD says unlimited fresh hay should be at least 80% of the diet, timothy for adults and alfalfa for young rabbits and breeding does, with rinsed leafy greens daily, high-calcium greens such as kale, spinach and parsley limited, carrots and broccoli kept to once or twice a week, a little fruit only as an occasional treat, and pellets as a supplement. Fresh water every day, in a bowl and a bottle until the rabbit shows a preference.

PDSA advises nuggets twice a day for rabbits over 3.5 kg, which covers most adult New Zealand Whites, always as a measured amount from your vet. The breed grows fast and gains weight easily, PetMD says, so the measure matters more than for most rabbits.

Meals a day: young rabbit, unlimited hay (alfalfa suits growing rabbits, PetMD says), with greens and pellets as your vet advises; adult over 3.5 kg, unlimited timothy hay; greens twice a day; nuggets twice a day; older rabbit, as your vet advises.

ARBA says the New Zealand was developed in the United States and recognised in 1916, prized for its quick growth and meat production, and that white pelts, being easier to dye, made the White the dominant variety. The Canadian Council on Animal Care's guide notes the breed is the one most widely used in Canadian laboratories, for its medium size and very docile nature, but that with age these rabbits usually become very heavy, tend to eat too much and develop sore feet.

That is the same pattern PetMD lists for pets: obesity, because the breed grows quickly and gains weight easily, and sore hocks, often caused by wire floors or dirty cages. A pet New Zealand White needs a solid, cushioned floor instead, and an enclosure at least four times its stretched-out length, as PetMD advises, with at least five hours a day out of it in a rabbit-proofed area.

PetMD calls the breed friendly, social and intelligent, able to learn tricks and use a litter tray, and generally easier to handle than smaller breeds. It may do better with a companion rabbit, and the RSPCA says rabbits should not live alone.

A study at Kerala Agricultural University described the New Zealand White, Grey Giant and Soviet Chinchilla as temperate breeds kept in the humid tropics of Kerala, and found the New Zealand White had the lowest death rate of the three before weaning. That tells us the breed can be raised here, not that it tolerates heat. The Merck Veterinary Manual's ideal range for rabbits is 15.5 to 21 °C at 40 to 60% humidity, and its rule of thumb is that the temperature in Fahrenheit plus the humidity percentage should not exceed 150.

Merck's farm advice in hot, humid weather is free access to cool water and sprinkling the hutches, and it notes that heat stress can leave breeding bucks infertile for weeks. For a pet in a flat, the Rabbit Welfare Association's steps fit better: shade, curtains shut, a marble surface, frozen bottles wrapped in a towel, a battery fan aimed at the bottles and plenty of cool water without ice. A heavy rabbit can find it harder to move to a cooler spot, so set up the coolest room before you leave.

The Merck Veterinary Manual calls uterine adenocarcinoma the most common tumour in rabbits, with an incidence that can reach 60% in unspayed does over 3 years old, and says it often spreads to the liver and lungs. Merck's management chapter adds that some strains have been reported to have an 80% likelihood of developing it by 3 years of age, and that this is the main reason for spaying does. PDSA says spaying removes the risk of ovarian and uterine cancer.

On timing, PDSA says females can be spayed from around five months, Merck suggests around sexual maturity, usually six months, and both note that larger rabbits mature later. Your vet decides. After surgery PDSA advises keeping the rabbit with its bonded partner in a quiet place, offering its usual hay and favourite greens, and calling the vet if it stops eating, since stress after surgery can bring on gut stasis. A sitter looking after a recently spayed doe should have the vet's discharge notes in writing.

PetMD says unlimited fresh hay should make up at least 80% of the diet, timothy for adults and alfalfa for young rabbits and breeding does, with rinsed leafy greens daily, high-calcium greens such as spinach limited, carrots kept to once or twice a week and pellets treated as a supplement. PDSA advises nuggets twice a day for rabbits over 3.5 kg, which covers most adult New Zealand Whites, in a measured amount.

Leave the measuring scoop, the same hay and pellets, and a list of greens. PDSA warns that changes should be made over two to four weeks, so the sitter should not swap brands even if a shop runs out: buy extra before you go.
