dc.description.abstract [EN] The effect of a treatment with a synthetic analogue of prostaglandin F2a (cloprostenol) administrated intramuscularly on day 28 of pregnancy in does belonging to a synthetic rabbit line selected by growth rate (line R) was studied. A reduction in gestation length was observed after treatrnent with prostaglandins (31.3±0.1 vs 32.4±0.1 days, for treated and control groups, respectively, P<0.05). Litter size at birth, and live-born pups were not affected by the treatment. Individual weight of young rabbits at birth was significantly different between treatrnent groups (52±1 vs 58±1 g, in treatment and control group respectively, P<0.05). In the control group, young rabbits born from multiparous does were heavier than those from pnm1parous (53±2 vs 63±1 g, in primiparous and multiparous does respectively, P<0.05). There were not differences in birth weight of kits from treated multiparous and primiparous does. At weaning, individual weight was not affected by treatrnent (578±12 and 561±10 g, in control and treatment group respectively), and differences were observed in reproductive status (513±12 vs 626±9 g, in primiparous and multiparous does respectively, P<0.05). An increase in mortality was observed during lactation period after treatrnent with PGF2a (48% vs 26%, in cloprostenol and control group respectively, P<0.01). es_ES
dc.description.abstract [FR] L'objet de ce travail est d'étudier l'effet de l'injection intramusculaire d'un analogue synthétique de la prostaglandine PGF2a {Cloprostenol) au 28éme jour de gestation a des lapines appartenant a une lignée synthétique sélectionnée sur la vitesse de croissance {lignée R). La durée de 9estation est réduite aprés traitement avec les prosta9landines (31.3±0.1 vs 32.4±0.1 jours, respectivement pour le lot traité et le lot témoin, P<0.05). La taille de portée a la naissance et le nombre de nés vivants ne sont pas modifiés par le traitement. Le poids individue! des jeunes lapereaux a la naissance est si9nificativement différent entre les lots (52±1 vs 58±19, respectivement pour le lot traité et le lot témoin, P<0.05). Dans le lot témoin, les jeunes lapereaux nés de lapines multipares sont plus lourds que ceux issus de primipares (53±2 vs 63±19, respectivement pour les primipares et les multipares, P<0.05). Dans le lot traité, le poids des lapereaux a la naissance ne varie pas selon qu'ils sont issus de lapines multipares ou primipares. Au sevra9e, le poids individue! des lapereaux n'est pas modifié par le traitement (578±12 et 561±109, respectivement pour le lot témoin et le lot traité) mais des différences sont observées selon la parité des lapines (513±12 vs 626±9g, respectivement pour les primipares et les multipares, P<0.05). Cependant, le traitement avec PGF2., s'accompa9ne d'une au9mentation de la mortalité pendan! la lactation (48% vs 26%, respectivement pour le lot traité au Cloprostenol et le lot témoin, P<0.01 ).
