  1. Descriptive characterization of a Nigerian heterogeneous rabbit population - factors affecting litter traits

    Oseni, S.O.; Ajayi, B.A.
    [EN] This study evaluated the effect of female body weight at conception (FWC), season of mating (SM), type of mating (TM) and litter size at birth (LSB) on the litter performance in a heterogeneous Nigerian population of rabbits. Data on 116 litters from 10 bucks and 48 does across three parities were analysed. Reproductive traits evaluated included LSB, number born alive (NBA), litter sizes and weights at 7, 14 and 21 d post-kindling, pre-weaning survival rate (SR) and daily weight gain of kits from kindling to weaning (DWG). A fi xed linear model that included FWC (light and heavy does),...

  2. Haematological and biochemical observations in four pure breeds of rabbits and their crosses under Egyptian environmental conditions

    Abdel-Azeem, A.S.; Abdel-Azim, A.M.; Darwish, A.A.; Omar, E.M.
    The present study was conducted to evaluate 16 crosses between 4 breeds of rabbits from a physiological point of view. The breeds tested were Baladi Red (BR), Chinchilla Giganta (ChG), French Giant Papillon (FGP) and Simenwar (S). A total number of 6144 blood samples were collected to detect the effect of crossing, age of kits, month of kindling and sex effects. The traits evaluated were: haematological parameters; red blood cell count (RBCs), haemoglobin concentration (Hb), haematocrit value (Ht%), biochemical parameters of plasma; total protein (TP), albumin (Alb), globulin concentration (Glo), albumin/globulin ratio (Alb/Glo) and triglycerides (TG). BR or its crosses,...

  3. Maternal behaviour in peripartum influences preweaning kit mortality in cage-bred wild rabbits

    González-Redondo, P.
    This study describes and models maternal nest-building and parturition behaviour in cage-bred wild rabbits (oryctolagus cuniculus), and its influence on the kits' pre-weaning mortality. In a total of 91 litters, perinatal mortality was 33%; mortality during the nursing period was 16.05%, and therefore the accumulated mortality up to weaning was 43.94%. These mortality rates, higher than those described in the literature among domestic breeds, were linked to failures in maternal behaviour. Such failures included the non-introduction of straw into the nest box (41.8% of births), a lack of hair lining in the nest (28.6%), births in which one or all...

  4. Detection of plant species-specific dna (barley and soybean) in blood, muscle tissue, organs and gastrointestinal contents of rabbit

    Tudisco, R.; Calabrò, S.; Bovera, F.; Cutrignelli, M.J.; Nizza, A.; Piccolo, V.; Infascelli, F.
    The aim of this study was to detect plant DNA sequences from low copy number genes of barley grain and soybean meal, the latter being subjected to solvent extraction process, in blood, liver, kidney, spleen, muscle tissue and digesta (duodenum, caecum and faeces from rectal ampulla) of rabbits. For fattening, Hyla rabbits (20 males and 20 females) were fed a diet including barley grain (15%) and soybean meal (12%). Animals were slaughtered at 74 d of age (2 ± 0.2 kg live weight) and samples collected from each animal. The quality of each DNA sample was verified using the UNIV...

  5. Milk production of pseudopregnant multiparous does

    Szendrö, Zs.; Matics, Zs.; Brecchia, G.; Theau-Clément, M.; Nagy, Z.; Princz, Z.; Biró-Németh, E.; Radnai, I.; Nagy, I.
    The aim of the experiment was to evaluate the milk production of pseudopregnant does. In this experiment, data of multiparous, inseminated, pregnant (IP, n=15) does and two groups of presumably pseudopregnant multiparous does: inseminated, non-pregnant (INP, n=17) and induced to ovulation by GnRH (1.5 microgram per animal) at the day of insemination (11 d after parturition) (non-inseminated, ovulating: NIO, n=15) were analysed. The progesterone level was measured at the 12th d after treatment to determine if females were pseudopregnant. All IP and NIO does were pregnant and pseudopregnant, respectively. Within the INP group, 10 and 7 does were diagnosed as...

  6. Evaluation of the anticoccidial efficacy of Cycostat (R) in experimentally infected breeding rabbits housed under conventional conditions

    Maertens, L.; Van Gaver, D.
    The present study was designed in order to evaluate the effi cacy and safety of Cycostat (R) 66G in the prevention and control of coccidiosis in breeding does after experimentally induced infection with common Eimeria spp. at the age of 18 wk. The inoculum was prepared based on faecal samples collected on farms in the Czech Republic. A total of 94 young and pregnant does were divided into 4 groups and enrolled in the study. The zootechnical, clinical and parasitological results of 2 control groups were compared, a non-infected non-treated (NI-NT) and an infected non-treated (I-NT), and 2 infected and...

  7. Diet digestibility in growing rabbits: effect of origin and oxidation level of dietary fat and vitamin e supplementation

    Casado, C.; Moya, V.J.; Fernández, C.; Pascual Amorós, Juan José; Blas, E.; Cervera, C.
    The effects of the dietary inclusion of fats with different origin (lard or vegetal oil), fatty acid profile (linseed or sunflower), oxidation level (fresh, peroxidised: 11 d at 55ºC or oxidised: 31 h at 140ºC) and vitamin E supplementation (0 or 100 ppm) on the rabbit diet apparent digestibility were studied. Digestibility coefficients of dry matter, organic matter, crude protein, ether extract and gross energy were determined in eight diets using 58 rabbits aged 49 d. Contrast analysis between groups of diets showed that lard, characterised by a greater saturated fatty acid content, compared with vegetal oils, rich in unsaturated...
