  1. RANDOMISED SANITARY STATUS OF ARGENTINEAN RABBITRY

    Martino, P.; Samus, S.; Piscopo, M.; Risso, M.; Lacchini, R.
    [EN] A short description of sanitary problems among argentinean rabbit farms (25 familiar and 41 cornmercial units), is presented. This randomized survey was compiled with information provided over the last 5 years by diverse diagnostic laboratories, centres and prívate farmers engaged in this activity. The pathological findings in the 426 autopsied animals, are similar to those described in the literature. Classical digestive and respiratory infections accounted for the most important causes of death : 43,2 and 25,8 %, respectively.

  2. NOTE: INDUCTION OF PARTURITION IN ANGORA RABBITS BY OXYTOCIN : SOME OBSERVATIONS

    Singh, G.; Katoch, B.S.
    [EN] The effect of oxytocin to induce parturition in angora does was studied. Retrospective observations were made on pregnant angora does maintained under ideal thermal and photo regulation and hygienic conditions. They were divided into two groups ; Group 1 (18 does), where oxytocin was used to induce parturition and Group 11 (8 does), where no oxytocin was used. To induce parturition, oxytocin (Sandoz®) 1 mi was injected intramuscul~rly on the 29th and 3oth days of pregnancy. Parturition occured in 8 of the 18 does between 12 and 30 minutes after injecting oxytocin. The 10 does did not respond to oxytocin and delivered kits only after two to...

  3. MORTALITY IN YOUNG RABBITS : A REVIEW

    RASHWAN, A.A.; MARAI, I.F.M.
    [EN] Mortality rate of young rabbits is of vital importance in commercial rabbit farming, since it determines the net income of the rabbitries. However, there is no definite proportion for mortality in young rabbits, since it may be less !han 10% in one situation in a given breed and reaches 100% in other situations, in the same breed. This may be due to susceptibility of the genotype to diseases and to the numerous uncontrollable externa! environmental factors. The significan! differences between breeds confirm that mortality can be genetically improved. Within the same breed, kit mortality during the suckling period decreases during the period between 4 and 12 months of...

  4. EFFETS DE L'UTILISATION DE LEVURES ENRICHIES EN CHROME SUR LA PRODUCTION DU LAPIN EN CROISSANCE

    Lambertini, L.; Vignola, G.; Zaghini, G.
    [EN] The aim of this trial was to investigate the effects of high chromium Cr) yeast supplemented diets on performance of growing-finishing rabbits. Ninety-six commercial hybrid rabbits, half males and half females, aged 35 days, were divided into experimental groups and fed, ad /ibitum, for 49 days the same basal diet supplemented with O (T1 ), 400 (T2), 800 (T3) or 1600 (T 4) ppb of Cr in the form of chromium enriched yeast. Control diet (T1) was analysed and found to contain 789 ppb Cr, a level which was due to the raw feed materials. The Cr content of all the diets was then proportionally increased. Chromium supplementation...

  5. EFFECT OF BIRTH WEIGHT AND LITTER SIZE AT SUCKLING AGE ON REPRODUCTIVE PERFORMANCE IN DOES AS ADULTS

    Poigner, J.; Szendrõ, Zs.; Lévai, A.; Radnai, I.; Bíró-Németh, E.
    [EN] A total of 121 Pannon White female rabbits born with low (39-43 g) or high (63-70 g) weight were raised in litters of 6 or 1 O kits. Their reproductive performance (Al practiced 9-11 days after kindling) was controlled for 6 consecutive litters for a total of 300 kindlings. The does' birth weight had a significant effect on the number of inseminations necessary for the first kindling: the higher the birth weight of does, the lower their kindling rate. Later on, however, birth weight no longer affected the conception rate. With higher birth weight, significantly improved doe performance could be expected. Litter size at birth was 12.4%...

  6. ALTERNATIVE FEED RESOURCES FOR FORMULATING CONCENTRATE DIETS OF RABBITS. 2. JACK BEAN (Canavalia ensiformis) SEEDS.

    Bamikole, M.A.; Ezenwa, I.; Adewumi, M.K.; Omojola, A.B.; Aken'ova, M.E.; Babayemi, O.J.; Olufosoye, O.F.
    [EN] In an eight-week long feeding and digestibility trial, the acceptable amount of heat-processed ( 1 h boiling) jack bean seed that can be used to substitute partially for oil cakes (palm kernel and groundnut cakes) in concentrate diets of rabbits was examined (8 rabbits 7-9 week old of local population per treatment). Four diets were formulated to contain O, 10, 20 and 30 % jack bean seed, respectively. The proximate composition of heat-processed jack bean (27.4 % crude protein, 14.2 % crude fibre and 51.1 % nitrogen free extrae!) showed that it has potential for use in rabbit feeding. Dry matter intake significantly declined with increasing levels of...

  7. ALTERNATIVE FEED RESOURCES FOR FORMULATING CONCENTRATE DIETS OF RABBITS. 1. UNTHRESHED GRAIN AMARANTH SEEDHEAD.

    Bamikole, M.A.; Ezenwa, I.; Adewumi, M.K.; Omojola, A.B.; Adetimirin, V.O.; Arigbede, O.M.; Orisadeyi, S.A.
    [EN] The acceptable leve! of inclusion of unthreshed inflorescence or seedheads of mature grain amaranth plants (GASH) as feed ingredient of concentrate diets of rabbits was examined. Four diets were formulated with GASH inclusion levels of O (control), 10, 20 and 30%, respectively, by partially replacing the levels of oil cakes in the diets. These were fed to rabbits in an eight-week long feeding trial (8 rabbits/treatment) and a digestibility trials (4 rabbits per treatment). The initial weight of the 7-8 week old rabbits was 710 g (adult weight of this population is 1 .8 to 2.4 kg). The proximate composition (g/kg DM) of GASH was : 151 crude...
