New Zealand rabbits were likely developed in California from a mix of breeds, possibly including Belgian hares [9] and Flemish giants. They were developed for their quick growth rate and meat type, and were added to the US rabbit standard in 1916. Originally they only came in red.
Suppose there are two species of animals, a rabbit (prey) and a fox (predator). If the initial densities are 10 rabbits and 10 foxes per square kilometre, one can plot the progression of the two species over time; given the parameters that the growth and death rates of rabbits are 1.1 and 0.4 while that of foxes are 0.1 and 0.4 respectively.
In its native Iberian and southern French range, European rabbit young have a growth rate of 5 g (0.18 oz) per day, though such kittens in non-native ranges may grow 10 g (0.35 oz) per day. Weight at birth is 30–35 g (1.1–1.2 oz) and increases to 150–200 g (5.3–7.1 oz) by 21–25 days, during the weaning period. [ 43 ]
This is the rabbit's way of marking their territory or possessions for other rabbits to recognize by depositing scent gland secretions. Rabbits who have bonded will respect each other's smell, which indicates a territorial border. [140] Rabbits also have scent glands that produce a strong-smelling waxy substance near their anuses.

Large mammals develop at an absolute slower rate compared to small mammals. Thus, the large mammal tend have longer gestation periods than small mammal as they tend to produce larger neonate. [ 18 ] Large mammals require a longer period of time to attain any proportion of adult mass compared to small mammals.
Rabbits are the seventh most popular pet in the U.S. Whether you own a bunny or want to, you may wonder how long it'll live. Here's a timeline.
The primary qualities of good meat-rabbit breeding stock are growth rate and size at slaughter, but also good mothering ability. Specific lines of commercial breeds have been developed that maximize these qualities – rabbits may be slaughtered as early as seven weeks and does of these strains routinely raise litters of 8 to 12 kits.
The English Lop, though longer and more slender in body than other lop breeds, has ears up to 79 cm (31.125 in) in length tip to tip—the longest ears of any rabbit breed. The ears of English Lops reach the end of their growth at approximately 5 months of age, although the ears of males can gain as much as an inch as their skull matures [clarify].
