Abstract:
The reproduction term of doe-rabbit using it is a season for
discussion, and it can be 4-5 years in non intensive systems of reproduction
or shorter to 1-3 years from 6-8 month when the monthly parturition are
received. There were two groups of doe-rabbit of California and White New
Zeeland breeds as a biologic material; there were 50 females in each group,
followed by six cycles of reproduction. There was established the kits number
at the parturition, their maintenance during the growing period, and the
number of weaned kits of both breeds. The best results were of received kits
had White New Zeeland breed – 7.58 kits received after six cycles of
reproduction, with the index between 6.75 and correspondingly 8.16 kits.
Another index which has to be discussed it is the number of received kits and
it is connected to the reproduction cycle, which had a growing evolution from
6.75 kits at the first cycle to 8.16 kits from the third cycle after that the kits
number dropped down to 7.06 at the fourth parturition. On the second place
there is the breed – California, with the average of received kits from six
reproduction cycles, with the variation from one cycle to another between
5.46 and correspondingly 6.89 kits, but the evolution of received kits depends
of reproduction cycle and very from 5.46 kits at the first cycle to 6.89 kits, at
fourth parturition. The both breed had the same conditions of feeding the
better adaptation had White New Zeeland. The percentage of kits
maintenance after tree weeks of their life of White New Zeeland breed was
per six reproduction cycles – 99.44%, from all kits received at the
parturition, but the California breed had this index – 99.05%. The average of
weaned kits per six reproduction cycles varied depending of received kits,
and differs on breed; it is from 6.09 kits for California breed to 7.33 for
White New Zeeland breed. The rabbit’s population what was studied is
described for good reproduction index, and it is recommended for using at
different farms.
