  1. UTILISATION OF FIELD BEANS BY GROWING RABBITS 1 - EFFECTS OF SUPPLEMENTATIONS AIMED AT IMPROVING THE SULFUR AMINO ACID SUPPLY.

    Berchiche, M.; Lebas, F.; Ouhayoun, J.
    [EN] One hundred New Zealand White rabbits distributed into five dietary groups were fattened between 35 and 77 days in indivicfuál ca9es. The diets were SOJ (soybean control), FEV (26.5 % f1eld beans), FEVM (FEV diet supplemented with di methionine), F'EVF (FEV diet supplemented with field beans up to a total of 37 %) and FEVT (FEV diet supplemented with sunflower cake) provided ad libitum. The mean protein content was 14.5 % in the SOJ, FEV and FEVM diets and 16.3 % in the FEVF and FEVT diets. The digestible energy content varied little between diets (2256 to 2324 kcal DE/ kg). The fibre content of each diet was 14.5 %....

  2. MAGNITUDE AND DIRECTION OF GENETIC-ENVIRONMENTAL INTERACTION IN RABBITS WITH SPECIAL REFERENCE TO LIVE AND SLAUGHTER PERFORMANCE AND CARCASS CUT-OUT

    Ayyat, M.S.; Anous, M.R.
    [EN] The data were collected on sixty New Zealand White (NZW) and sixty Californian (CAL) weaned male rabbits used to investigate the magnitude and direction of genetic environmental mteraction. Ralf the rabbits in each group was fed ad libitum on commercial pelleted ration containing Zinc bacitracin (ZIN) and the other half on ration containing Flavomycin (FLA). F'or all rabbits, daily gain, daily feed intalromoter type group (n = 15) were slaughtered after 8 weeks from weaning and evaluated for slaughter and carcass cut-out...

  3. EUROPEAN REFERENCE METHOD FOR IN VIVO DETERMINATION OF DIET DIGESTIBILITY IN RABBITS

    Pérez, J.M.; Lebas, F.; Gidenne, T.; Maertens, L.; Xiccato, G.; Parigi-Bini, R.; Dalle Zotte, A.; Cossu, M.E.; Carazzolo, A.; Villamide, M.J.; Carabaño, R.; Fraga, M.J.; Ramos, M.A.; Cervera Fras, Mª Concepción; Blas Ferrer, Enrique; Fernández, J.; Falcao e Cunha, L.; Bengala Freire, J.
    [EN] This paper describes a standardized method for in vivo determination of total digestibility in rabbits. This method was working out within the European Group on Rabbit Nutrition (EGRAN) which involves six laboratories from five countries (Belgium, France, ltaly, Portugal and Spain). The aim of the group was to propose a method at once reliable, quick and- simple. This new rnethod can be regarded as a baseline for calibrating individual laboratory procedures. The method is based on 7 to 8 weeks old rabbits caged individually and fed ad libitum. The pre-experimental period lasts 7 days and the collection period only 4 days. For either feed and faeces, standardized conditions of...

  4. EFFECT OF SIRE STRAIN, FEEDING, AGE AND SEX ON RABBIT CARCASS

    Bernardini Battaglini, Marcella; Castellini, C.; Lattaioli, P.
    [EN] The effect of sire strain, feeding plan, slaughter age and sex on the carcass g~~lity were studied on 120 crossbred rabbits (White Giant (vvG), Heavy Grimaud Fréres (HGF), Light Grimaud Fréres (LGF) with New Zealand White does]. Two feeding plans were used : plan H consisting of a high energy diet (10.42 MJ DE/kg ; 12.14 % DP) from weaning to slaughtering (75 days or 90 days of age) ; plan LH consistíng of a low energy d1et (9.85 MJ DE/kg ; 11.51 % DP) until 55 aays, and a higfl energy diet up to 75 or 90 days. The sire strain affected growth performance and carcass traits...

  5. EFFECT OF ORAL ADMINISTRATION OF YEAST ( Saccharomyces cerevisiae ) ON DIGESTIBILITY AND GROWTH PERFORMANCE OF RABBITS FED DIETS OF DIFFERENT FIBRE CONTENT

    Chaudhary, L.C.; Singh, R.; Kamra, D.N.; Pathak, N.N.
    [EN] Thirty two laboratory strain New Zealand White rabbits aged about 6 weeks were divided into 4 equal groups. Rabbits were fed diets of 9. 73 % (/DM) fibre in group 1 and 2, and 12.86 % fibre in group 3 and 4. Yeast culture (Saccharomyces cerevisiae) ata rate of 5 x 1oa cells /animal /day was given orally to group 1 and 3. Dry matter intake was significantly (P<0.01) higher in the rabbits given high fibra diet but tlie digestibility coefficients of dry matter, organic matter, ether extract, nitrogen free extract and feed conversion efficiency were significantly better in the animals given low fibre diet. Adminisfration of yeast...

  6. EFFECT OF DILUENT AND STORAGE TIME OF RABBIT SEMEN ON THE FERTILITY OF DOES REARED UNDER TWO DIFFERENT LIGHTING SCHEDULES

    Maertens, L.; Luzi, F.
    [EN] Using a 3-factorial design, the effect of two commercial diluents (IMV vs Minitüb), two storage times (fresh vs 6h storage at ambient temperature) and a lighting schedule was stud1ed on artificial inseminated does. During a 1 O month experimental period 140 (nulliparous and multiparous) does were randomlr divided in two production groups and submitted to a 16h :8hD continuously lighting schedule or to a 10hL:14hD schedule. In order to synchronize the oestrus, the lighting period was suddenly increased till 16hL from 5 days before the insemination (alternative lighting). Both production groups were inseminated every a weeks with an interval of 3 weeks between them. In total 988 inseminations were performed with an...

  7. ALBINO RABBITS CAN SUFFER FROM MEGACOLON-SYNDROME WHEN THEY ARE HOMOZYGOUS FOR THE ENGLISH SPOT"" GENE (EnEn)""

    WlEBERNEIT, D.; WEGNER, W.
    [EN] Segregation patterns, reproduction rate, mortality, fattening performance and gut parameters of albino (ce) ralfüits heterozygous (Enen) or homozygous (EnEn) for the English Spot gene have been investigated to test the hypothesis whether albinos can suffer from MegacolonSyndrome, which is a characteristic predisposition of EnEn spotted animals. Whereas the weight of the gut (brutto) of ce Enen - animals reached 8.5 ± O. 7 % of live weight at slaughter and 17 .2 ± 1.6 % of the carcass weight, ce-En En animals exhibited a relativa gut weight of 16.5 ± 6.5 % and 37.0 ± 17.4 % respectively. rn addit1on to these findings one cc-EnEn breeder buck suffered chronically...
