  1. UTILISATION DE DIFFERENTS TYPES DE GRIGNONS D'OLIVE DANS L'ALIMENTATION DES LAPEREAUX

    Chaabane, K.; Bergaoui, R.; Ben Hammouda, M.
    [EN] Four rations were formulated and tested. The control diet contains 34% of alfalfa mea!. The others contain 30% of one of the olive cakes : crude olive cake (feed B), exhausted olive cake (feed E) and cake from super presses (feed C). The digestibnle energy content of the olive oil cakes are estimated at 2200, 1700 and 835 kcal/kg respectively for the crude, exhausted and super presses olive cakes. After granulation the dry matter of the feed C was the same than the other feeds in spite of high leve! of water in the cake (60%). The digestibility, using 16 rabbits of 8 weeks of age, of...

  3. RATE OF PASSAGE IN THE RABBIT DIGESTIVE TRACT : INFLUENCE OF MARKER DOSING TIME, ILEAL CANNULATION AND MARKER TYPE

    GlDENNE, T.; LAPANOUSE, A.
    [EN] A control group of 5 adult rabbits and a group of 4 ileocannulated rabbits, fed ad libitum were used to assess the effect of marker dosing time, marker type (Ytterbium vs Cerium labelled cellwall) and the effect of the ileal cannulation, on measureme~~ of passage rate (RPM). The passag;¡.P,te of particles labelled with Yb was equal to those labelled with Ce, and allowed the comparison of RPM obtained with these two markers given at different times to the animals. In our experimental conditions, over 70% percent of the animals showed no hard faeces excretion between 10:00 and 16:00, because of soft faeces excretion during this period. The total mean...

  5. MODIFICATIONS OF SOME PARAMETERS OF THE RABBIT EJACULATE AFTER ABLATION OF THE VESICULAR GLAND

    Niño Jesús, A. Del; Muños López, I.; Josa, A.; Espinosa, E.; Gracia, M.; Martínez, M.P.
    [EN] An evaluation is made of the influence which the vesiculectomy may have on the ejaculate in the rabbit. To do this we have studied three different factors in the semen, before and after the operation: quality control parameters (volume, vitality and concentration), presence or not of the mucous plug and levels of different ions (sodium, potassium, calcium and magnesium) in the rabbit's seminal ¡tasma. At the same time we performed periodical determinations o these ions in the blood plasma, in order to rule out the fact that the variations of the cation levels in the seminal plasma could be due to alterations of these levels in the...

  8. FASTING EFFECTS ON IN VITRO FERMENTATION PATTERN OF RABBIT CAECAL CONTENTS

    Piattoni, F.; Demeyer, D.; Maertens, L.
    [EN] Caecal contents were collected from six 16h fasted (F) and six non fasted (NF) rabbits, sacrificed between 9 and 1 Oam. They were incubated for 24h/39ºC and net productions of volatile fatty acids (VFA) and methane were determined. In a separate preliminary experiment, caecal contents obtained from a F and a NF rabbit were incubated with starch, cellulose or pectins. In F animals, total VFA concentration was lower (P<0.001) and caecal pH significantly higher (P=0.015) than in NF enes: 6.5 vs 6.2. Molar proportions of propionate were higher than butyrate (11.3 vs 4.0%) in F rabbits. However, the latter became higher after 24h of in vitro incubation....

  10. ENILCONAZOLE AS A TREATMENT OF NATURALLY OCCURRING DERMATOPHYTOSIS IN RABBIT FARMS : A REVIEW.

    Rochette, F.; Van Meirhaeghe, P.
    [EN] This article summarises six clinical trials with the antimycotic enilconazole carried out in four countries. lt is concluded that desinfection with enilconazole spray of the total environment (walls, ceiling, cages, etc.) in rabbit stables is an effective way of controlling dermatophytosis. The number of ringworm les1ons regressed substantially after the application of the ready-to-use spray. A high dosage of 50 mg/m2 enilconazole was applied because caging and nest materials and other litter were present. No sideeffects were observed. This treatment should be carried out twice weekly in batteries filled with rabbits and should be continued for at least 3 weeks.

  12. EFFECTS OF DIETARY FAT ON REPRODUCTIVE PERFORMANCE OF RABBIT DOES : A REVIEW.

    Fortun-Lamothe, L.
    [EN] Addition of fat permits a noticeable increase of digestible energy intake by rabbit does (231 kJ per day I 1 % ether extract). Additional energy intake is used in priority for rnilk production. This leads to heavier young rabbits at weaning {+2.1 % for each 1 % increase in ether extract). Fat inclusion also rnodify rnilk cornposition {fatty acids proportions), but influence on suckling rabbits survival is unclear. Effects of dietary fat on fertility of rabbit does are non existent or positive. Positive effects should be overall related to the increase of dietary energy content associated with fat inclusion. Effects on prolificity are controversia!. Finally, fat addition seerns...

  14. COURTE NOTE : NEPHROBLASTOME (TUMEUR DU REIN) SPONTANÉ CHEZ UNE LAPINE D'ELEVAGE (Oryctolagus cuniculus)

    BOUCHER, S.; PLASSIART, G.; NOUAILLE, L.; ANJOT, P.
    [EN] During a routine autopsy, the authors had discovered a tumor on a 8 month old doe's kidney issue from a commercial ligne « Hy-plus ». The histological test revealed a nephroblastoma, one of the young's tumor with not very differentiated cells. lt reproduces the structures of the embryonic beginnings of the kidney. Diagnostic possibilities, possible treatments comparad with the human ones and the origin of sorne genetic aspects of neprhoblastoma are mentionned.

  16. CHANGES IN PLASMA PROGESTERONE AND ESTRADIOL DURING NATURAL PROSTAGLANDIN F2a-INDUCED PARTURITION IN THE RABBIT.

    Rebollar, P.G.; Alvariño, J.M.R.; Illera, J.C.; Silvan, C.; Lorenzo, P.
    [EN] The influence of administration of natural prostaglandin F2a (PgF) on plasma progesterone (P4) and estradiol-17(l (E2) levels during the last days of pregnancy (days 29-32) was studied in 13 doe rabbits of the California x New Zealand White breed. Animals were allocated to receive either a single intramuscular injection of 800 or 1200μg of natural PgF on day 29 of pregnancy at 10 h (treated groups) or no injection (control group). AH does treated with PgF kindled within 60 h after injection, whereas the variation in birth time in control group was greater (79.2 ± 8.9 h). No influence of the prostaglandin treatment on mean plasma estradiol...
