The period of gestation of rabbits and its fertility connection

Abstract

The work researched the effect of multiple pregnancy on the gestation period of a female rabbit. To research the reproductive characteristics of female rabbits, physiologically mature live weight of at least 3 kg was selected. The reproductive characteristics of female rabbits were researched during three births. In the experiment, we used rabbit breeds such as New Zealand white and white giants, which were mated according to the scheme NZBxNZB and NZBxWG. The first litter of rabbits was analyzed as a control, and the second and third litters were analyzed as experimental groups. In the experiment, the polygamy ratio was 5:1. Female rabbits were mated in the morning and evening. The day of mating and the day of birth were recorded. The results obtained show that the length of the gestation period in rabbits is directly affected by the number of offspring. It has been established that the gestation period lasts longer in rabbits with a small number of offspring compared to rabbits with a large number of offspring.
