| Abstract |
A total number of ninety multi porous suckling does in two sequence parities and ten sexually mature bucks of Californian rabbits aged 9 months was used in the present work. The study was designed to evaluate the effect of mother-litter separation as a bio stimulator and PMSG as a hormonal stimulator on fertility traits of suckling Californian rabbit does inseminated artificially.
The rabbit does were divided into three comparable experimental groups and treated as follows:
i The first group (control): does injected intramuscularly with 20 μgm Gn-RH/ head an hour before artificial insemination.
ii The second group: does treated as in the first group and separated ftrom their litters 24 hours before artificial insemination.
iii The third group: does treated as in the second group in addition to , intramuscular injection with 50 IU PMSG/ head 72 hours before artificial insemination.
The obtained results could be summarized as follows:
Mother litter separation 24 hours before artificial insemination increased fertility traits of suckling Californian rabbit does significantly (P<0.01) represented by (kindling rate, litter size and weight at birth and milk yield during lactation period). Bunny weight and bunny daily weight gain during suckling period also increased significantly (P<0.01), while the rate of bunny preweaning mortality significantly (P<0.01) decreased due to mother litter separation.
Injecting 50 IU PMSG/ head and mother litter separation combined with 20 μgm Gn-RH injection! head at intervals of 72, 24 hours and one hour, respectively, before artificial insemination had highly significant (P<0.01) effect on fertility traits of suckling Californian rabbit does and also on their offspring performance.
Key words: Rrabbit, GncRH, mother-litter separation, PMSG, AL, fertility, litter.
