  1. The effect of unilateral ovariectomy on early embryonic survival and embryo development in rabbits

    Peiró Barber, Rosa Mª; Gallego, M.; Blasco Mateu, Agustín; Santacreu Jerez, María Antonia
    [EN] Unilateral ovariectomy can be used to study uterine capacity in rabbits because an overcrowding of the functional uterine horn is produced. Due to the uterus duplex, the rabbit is the ideal model for such studies. However, this technique may affect embryo survival. The aim of this work is to study the effect of unilateral ovariectomy on early embryo survival and development in rabbit. A total of 101 unilateral ovariectomised females and 52 intact females were compared after slaughter at 30 h post-mating. Early embryo survival was estimated as the ratio between number of embryo recovered and ovulation rate. No...

  2. Rabbit production in low-input systems in Africa: situation, knowledge and perspectives – A review

    Oseni, S.O.; Lukefahr, S.D.
    [EN] High poverty levels continue to plague much of Africa despite several intervention strategies aimed to stem the tide. The role of small livestock like rabbits as a tool in poverty alleviation programmes has been acknowledged for decades and successful national rabbit projects have clearly been demonstrated in Africa. With rising poverty levels across Africa, the need to rejuvenate such national rabbit projects for long-term sustainability becomes apparent. This presentation focuses on the status of rabbit production in Africa, with special attention to smallholder rabbit project development and its connection with poverty alleviation issues in the continent and with an...

  3. Post-weaning growth of endemic Iberian wild rabbit subspecies, Oryctolagus cuniculus algirus, kept in a semi-extensive enclosure : implications for management and conservation

    Ferreira, A.; Ferreira, A.J.
    [EN] Little is known about the endemic Iberian wild rabbit subspecies, Oryctolagus cuniculus algirus, despite its importance in Mediterranean ecosystems. An individual’s physical condition is of undisputed importance when evaluating the quality of habitats or restocking enclosures to assess the corresponding population status. We analysed post-weaning body weight and growth of 351 individuals of the endemic Oryctolagus cuniculus algirus subspecies under semi-natural conditions in a breeding enclosure in central Portugal. From these data, we described and estimated growth rates for juvenile and adult stages, and 3 sigmoidal growth models were developed. Body weight showed a linear growth of 0.00765 kg/d...

  4. Effects of substitution of soybean meal-alfalfa-maize by a combination of field bean or pea with hard wheat bran on digestion and growth performance in rabbits in Algeria

    Lounaouci-Ouyed, G.; Berchiche, M.; Gidenne, T.
    [EN] The aim of the trial was to study the effects of replacement of a soybean meal-alfalfa-maize based diet by a mixture of field bean (g/kg as fed: 257 crude protein [CP], 139 neutral detergent fibre [NDF]) or pea (g/kg as fed: 203 CP, 122 NDF) combined with hard wheat bran (g/kg as fed: 140 CP, 396 NDF) and without supplementation of synthetic DL-methionine, on diet digestibility, growth and slaughter traits of growing rabbits. Three diets were formulated: a control diet mainly consisting of 15% of soybean meal, alfalfa and maize (SBM15 diet; g/kg as fed: 161 CP and 267...

  5. Effect of hesperidin dietary supplementation on growth performance, carcass traits and meat quality of rabbits

    Simitzis, P.E.; Babaliaris, C.; Charismiadou, M.A.; Papadomichelakis, G.; Goliomytis, M.; Symeon, G.K.; Deligeorgis, S.G.
    [EN] An experiment was conducted to examine the dose effects of hesperidin dietary supplementation on fattening rabbits’ growth performance, as well as carcass and meat quality characteristics. Forty-eight Hyla hybrid male weaned (35 d old) rabbits were purchased and randomly assigned to 3 dietary groups of 16 rabbits each and fed diets supplemented with the antioxidant hesperidin at 0, 1 and 2 g/kg feed. At 80 d of age, the rabbits were slaughtered and samples of Longissimus lumborum (LL) muscle were used to estimate meat quality traits. No significant differences were observed in body weight at the age of 80...

  6. Digestible energy of unpeeled cassava root meal and its effect on growth performance and carcass traits in rabbits

    Mora, L.M.; Moura, A.S.A.M.T.; Scapinello, C.; Bicudo, S.J.; Araújo, I.G.; Curcelli, F.; Barros, T.F.M.
    [EN] Two experiments were conducted to evaluate the use of cassava root meal (891 g dry matter [DM]/kg, 639 g starch/kg, 74.1 g neutral detergent fibre [NDF]/kg, and 26.6 g crude protein [CP]/kg) in diets for growing rabbits. In the first experiment, a basal diet (419 g NDF/kg and 181 g CP/kg) and a test diet, in which cassava replaced 25% of the DM of the reference diet, were used. Twenty 50-d-old New Zealand White rabbits weighing 1474±10 g were randomly assigned to the 2 treatments, and digestibility of DM and gross energy (GE) were determined. The inclusion of cassava...

  7. Dehydrated chicory pulp as an alternative soluble fibre source in diets for growing rabbits

    Maertens, L.; Guermah, H.; Trocino, A.
    [EN] Soluble fibre (SF) is an important nutrient to enhance fermentative activity and gut health in rabbits. The main source of SF in rabbit diets is sugar beet pulp (SBP), whereas, due to its high content of SF (34%), dried chicory pulp (ChP) could be an alternative to SBP. In a fattening trial with 192 hybrid weanlings 32 d old weighing 837±45 g, chicory pulp was used in replacement of SBP to study effects on production performances and slaughter characteristics. Rabbits were fed one of 4 iso-energetic (9.65 MJ digestible energy/kg) and isonitrogenous (15.6% crude protein) diets: a negative control...
