  1. VITAMINS IN RABBIT NUTRITION : LITERATURE REVIEW AND RECOMMENDATIONS

    Lebas, F.
    [EN] Vitamins are classified in a total of 13 substances or groups of substances. Four vitamins are fat-soluble (vitamin A, O E, and K) and the nine others (vitamins of the B-complex and vitamin C) are water-soluble. The water-soluble vitamins and vitamin K are normally synthesised by the rabbit's digestive flora; but in cases of high risk of digestive disorders (e.g. just after weaning), dietary supplementation may be advisable. In addition, a vitamin C supplementation (25 to 30 mg per rabbit and per day) can help the animal in stress situations (heat stress, ... ). The vitamin A requirement is largely satisfied if the diet contains 1 O 000...

  2. PROENOFOS EFFECTS ON RABBIT PERFORMANCE AND THEIR AMELIORATION BY USING NATURAL CLAY MINERALS

    Ayyat, M.S.; Abd el-Monem, U.M.; El-Gendy, H.M.; El-Fateh Hammad, M.
    [EN] Eighty New Zealand White male rabbits of 35 days of age, were used in the present study. The rabbits were randomly allotted to 8 groups with 10 animals in each. Four groups were fed diets contaminated with O, 0.658, 1.315, 2.630 mg proenofos/kg diet. The other four groups fed the same diets but supplemented with 5% natural clay (80% betonite). Rabbits fed with diet contaminated with proenofos (an organophosphorus insecticide) decreased feed intake, final live body weight (-22% for the highest leve!), daily gain, heamoglobin, serum total protein, albumin, SGPT and cholinesterase while mortality rate, SGOT, urea-N and creatinine increased. Feed conversion impaired with increasing pesticide level in rabbit...

  3. Note: An original system to separately control litter and female feed intake without modification of the mother-young relations.

    Fortun-Lamothe, L.; Gidenne, T.; Lapanous, A.; De Dapper, J.
    [EN] This paper describes an original system allowing separate control of the feed intake of the mother and of her litter without rearing them in separate cages, and thus without modifying young I mother relations. This system involved severa! modifications on traditional wire cages. Firstly, !he female's feeder was modified to preven! the ingestion of pellets by the suckling rabbits. Secondly, young had access to a specific feeder. Lastly, a wire mesh partition divided the cage in two areas, to avoid !he doe having access to !he young's feeder. Females need to be adapted to their new feeder at leas! two weeks befare the beginning of the control...

  4. HISTOCHEMICAL STUDY OF NON-SPECIFIC ESTERASE ACTIVITY IN SMALL AND LARGE INTESTINE OF YOUNG RABBIT

    Sabatakou, O.; Xylouri-Frangiadaki, E.; Paraskevakou, E.
    [EN] The distribution of non-specific esterase in normal duodenal, jejunal, ileal and large intestinal mucosa of the rabbit has been studied using histochemical methods. Thirty three New Zealand White rabbits were used ranging from 26-day old fetuses to 43-day old young (3 rabbits I age). Distribution and intensity (strong to very strong) varied little throughout the small and large intestine from the 301 h day of foetal life and as after birth up to 43 days. At the 26 or 281 h days of foetal life only mild to positive reactions were seen. 1 In the caecum and in the upper colon, a low non-specific esterase activity was observed...

  5. HISTOCHEMICAL DISTRIBUTION OF LEUCINE AMINOPEPTIDASE (LAP-ase)IN THE YOUNG RABBIT INTESTINE

    Sabatakou, O.; Xylouri-Frangiadaki, E.; Paraskevakou, E.
    [EN] The distribution of leucine aminopeptidase in normal duodenal, jejunal, ileal, crecal and colonic mucosa of the rabbit has been studied using a histochemical method. Thirty New Zealand White rabbits were used ranging from 26-day old foetuses to 43-day old young (3 rabbits per age). Small intestine siles performed a leucine aminopeptidase reaction starting from the 301 h day of foetal life. After birth the reaction was variable in intensity up to 19 days of age, while in older animals it became very strong. Similarly, the large intestine followed the same pattern with the exception that from the 241 h day of age onwards it performed no reaction.

  6. EFFECT OF LYSINE AND METHIONINE ON LIBIDO AND SEMEN CHARACTERISTICS OF BUCKS

    Nizza, A.; Dimeo, C.; Taranto, S.
    [EN] The aim of this experiment was to study the influence of dietary lysine and methionine levels on the libido and semen quality of bucks. Forty crossbred Hyla HYLA rabbit males (10-12 months old) were subjected to four diets (15% crude protein) differing in lysine and methionine content (diet A 0.64 and 0.58%; diet B 0.75 and 0.58%; diet C 0.64 and 0.65%; diet D 0.75 and 0.65 of lysine and methionine +cystine, respectively). Two successive ejaculates were collected once a week for 12 consecutive months. Semen evaluations of for volume, colour, pH, motility, concentration and percentage of live spermatozoa were performed every two weeks. Dietary supplementation with lysine and...

  7. DAM AND LITTER INBREEDING AND ENVIRONMENTAL EFFECTS ON LITTER PERFORMANCE IN BOTUCATU RABBITS

    MOURA, A.S.A.M.T.; POLASTRE, R.; WECHSLER, F.S.
    [EN] The purpose of this study was to evaluate the effects of the inbreeding of the dam (Fd) and of the litter (F1), parity of dam, and month and year of birth on number of young born alive (NBA) and weaned per litter (NW), total litter weaning weight (LWW), mean weaning weight (MVVW) and litter pre-weaning mortality rate (LM) in Botucatu rabbits. Data on 1,065 litters were collected from 1992 to 1994 at the UNESP rabbitry located in Botucatu, SP, Brazil, and analysed by least-squares method. Litters were weaned at 30 days of age. Values of Fd and F1 ranged from zero to 0.3309 and averaged 0.0717 ± 0.0015...
