.Rabbit production and remating interval

Abstract: Rabbit producers must apply proper management to maximize the profit of their economic activity.
Improving rabbit reproductivity is still the main objective for many investigators to detect the several factors
affecting it. Mating frequency and remating interval may play an essential role especially in intensive rabbit
production. The number of bunnies which a doe should be gave during the year is often verey important
objective of the breeder. Regarding rabbit semen, in two successive rabbit ejaculates, the first ejaculate acts
as a preparation for the second which is less voluminous but more concentrated and viability. Repeating the
mating twice with about an hour apart increased the number of ovulated follicles. So, the best conception
rate recorded by does having two coitus with an hour apart. The present article proved that the earliest
remating (on the 1st day post partum) showed the more successful reproductive performance of rabbit does
than the cases of later remating. The only drawback of the early remating is the low growth rate of suckling
bunnies, most probably due to the exhaustion of the dams by the two coinciding bio-physiological events of
suckling the born litter along with the next pregnancy which is apt to reduce its capacity of nursing the
offsprings by enough milk and/ or changes in its nutrient composition. Consequently, the dam has to be
reinforced by more good quality feeds balanced in energy and protein as well as the proper supply of the
required minerals and vitamins. This dam litter relationship as affected by the composite condition of system
of mating and nutritional status is still in need to further studies. This drop in the weight of the bunnies by
early remating is compensated by the high number of bunnies per litter. On the other hand, the earliest
remating results in gaining more parities within a certain period (one year for example) than the later mating
thus having more offsprings for rearing and marketing. The expected economic outcome of rabbit production
may maximize by applying remating on the 1st day post partum inspire of the excess in feed utilization.
