  1. THE EFFECT OF INFRA-RED RADIATION ON RECTAL, SKIN AND HAIR-TIP TEMPERATURES OF RABBITS.

    Kasa, I.W.; Thwaites, C.J.
    [EN] An experiment was conducted on the effect of infra-red (i.r.) radiation on female NZ>/11 rabbits. A 4x3x6 factorial design was employed in which the factors were : 4 intensities of i.r. radiant heating of O.O, 1.9, 2.1, 2.4 MJ/m2/h ; 3 replicates and 6 rabbits. All animals were watered and fed a standard ration ad libitum. Rectal temperaturas differed (P<0.001) between treatments and were highest at the "high" level of i.r. radiation (1 ºC higher than far controls). At the "medium" and "low" levels of i.r. heating RT's were respectively 0.3º and 0.2ºC higher than in controls. In different i.r. treatments skin temperatura (ST) was significantly different (P<0.001), being highest...

  2. RECHERCHES SUR L'INTERACTION ENTRE ALIMENTATION, REPRODUCTION ET LACTATION CHEZ LA LAPINE, UNE REVUE

    Parigi-Bini, R.; Xiccatto, G.
    [EN] The rabbit doe, at the beginning of its reproductiva activity (first pregnancy first lactation or first" concurrent pregnancy and lactation), hás a negativa energy and material balance. The net body composition at the first parturition changes definitely during lactation, with an important loss of lipids (about - 40 %) and energy (- 20 %). lf the rabbit doe is concurrently pregnant, the energy deficit becomes greater and the nitrogen and mineral balances become negativa as well. Consequently the second kindling litter size is lower, (- 10 % of total youngs born and - 20 % of rabbits born alive). Moreover, the composition of new born pups shows a lower lipid...

  3. EMBRYO RECOVERY UNDER ANAESTHESIA AFTER hCG OR GnRH TREATMENTS IN THE RABBIT AND SURVIVAL WHEN A REDUCED NUMBER OF EMBRYOS IS TRANSFERRED

    LOPEZ, Marina; FORCADA, F.; RODRIGUEZ, J.A.; MARTIN, Maria; ZARAGAZA, L.
    [EN] Ovulation rate and number of 72h post-mating recovered embryos were studied in nulliparous Spanish Giant does treated with an intravenous injection of 25 IU hCG (n=22) or 20 μg GnRH (n=20) intramuscularly after coitus. Embryos were recovered under anaesthesia by separata perfusion of the oviducts and uteri. One of the GnRH-treated does did not ovulate. No significant differences between groups were found either in the ovulation rate or in the number on recovered embryos per donor doe (8.5 ± 0.2 and 7.3 ± 0.2 vs 8.6 ± 0.4 and 6.8 ± 0.9 respectively for hCG and GnRH treated animals). After transfer into the uteri of synchronized Solaf commercial hybrid recipients,...

  4. DIVERSITY OF REPEATABILITY BETWEEN PARITIES FOR LITTER TRAITS AND REPRODUCTIVE INTERVALS IN DOE RABBITS.

    Khalil, M.H.
    [EN] An experiment was carried out to determine the genetic variation in litter traits and reproductiva intervals between different parities in New Zealand White (NZW) and Californian (CAL) rabbits. Data on 581 litters produced by 163 does mated to 43 bucks of NZW and CAL rabbits were involved. A linear mixed model included the effects of service buck and does within service buck (as random effects) and year-season and parity (as fixed effects) was used for analysing such data. NZW breed had higher litter size, weight and gain along with a lower number of stillbirths and preweaning litter mortality relativa to CAL breed. Reproductiva intervals and number of services per conception of...

  5. CASSAVA AS NEW ANIMAL FEED IN EGYPT 3 - PELLETED COMPLETE CASSAVA FEED FOR GROWING RABBITS.

    Abd El-Baki, S.M.; Nowar, M.S.; Bassuny, S.M.; Hassona, E.; Soliman, E.S.
    [EN] Forty New Zealand White rabbits (20 males and 20 females) aged 5 weeks, of 735g in average weight, were divided into two groups on basis of weight and sex. A pelleted complete rabbit feed containing 45 % cassava products (CCF diet) as 30 % root meal + 15 % leaf meal, was formulated to be fed in comparison with a commercial feed (AF diet ; Atmida Cº) during the 15 weeks of experiment, divided in 3 stages of 5 weeks. 1 % urea was added to the CCF diet in arder to increase the N-content. The results indicated that CP digestibility and N-balance of CCF were significantly (P<0.05) lower...
