  1. TECHNICAL NOTE : THE MEASUREMENT OF SOFT FAECES PRODUCTION IS AFFECTED BY THE TYPE OF COLLAR

    Gidenne, T.; Lapanouse, A.
    [EN] The present study aimed to compare two types of plastic collar, either a rigid and flat one or a flexible and conical one, for collecting soft faeces. Measurements were performed in two successive series (separated by 5 days) on a group of 1 O hybrid adult rabbits (mean live weight = 3590 g) fed ad libitum a commercial pelleted die! . Rabbits equipped with a flat collar showed a slightly higher (not significan!) feed intake, and a higher hard faeces excretion (+ 10%). The quantity of soft faeces collected was 20% higher (P=0.05) in rabbits wearing a flat collar, compared to a conical one (resp. 28.2 vs...

  3. SHORT TERM ACUTE HEAT STRESS IN RABBITS: FUNCTIONAL, METABOLIC AND IMMUNOLOGICAL EFFECTS

    Amici, A.; Franci, O.; Mastroiacono, P.; Merendino, N.; Nardini, M.; Tomassi, G.
    [EN] Sixteen male New Zealand White rabbits (NZW) accustomed to an environmental temperature of 18.0 ± 0.5 ºC , and relative humidity of 45 ± 4% were placed in a climatic chamber for 1 hour at 42 ºC with r.h. maintained at 45 ± 4%. Feed consumption, rectal temperature and body weight were registered individually for five days before and five days after the heat stress. Blood samples were collected befare the exposition to the stress temperature, and at 0.5 h, 6 h, 30 h and 54 h after the end of exposure to stress. Plasma and peripheral blood mononuclear cells (PBMC) were prepared. Glucose, urea, total cholesterol and...

  5. RECENT ADVANCES IN RABBIT NUTRITION : EMPHASIS ON FIBRE REQUIREMENTS. A REVIEW.

    GlDENNE, T.
    [EN] The rabblt meat production knew deep modifications during the ten last years, on the techniques of breeding as well as on the genetic potentialities of growth or reproduction. The techniques of feeding (adapted feed formulation etc.) also strongly progressed, in arder to obtain a better adjustment of feeds to the animals needs, e.g. according to their physiological stage. This paper summarised the recent advances and perspectives, which we consider significan! in the field of the nutrition of growing rabbits and reproductive females. Particular attention will be devoted to the dietary fibre definition and requirements and to the relationship with digestive pathology, as mortality by diarrhoea is still...

  6. MEAT QUALITY AND CAECAL CONTENT CHARACTERISTICS OF RABBIT ACCORDING TO DIETARY CONTENT AND BOTANICAL ORIGIN OF STARCH

    Nizza, A.; Moniello, G.
    [EN] The research was carried out to study the influence of diets differing in contents and botanical origin of starch on fattening and slaughtering performance of rabbits. Four pelleted diets (LSM, LSW, HSM, HSW) were prepared according to a 2 X 2 factorial scheme: two starch contents (23 vs 28% DM) and two botanical origins (wheat vs maize). Before being slaughtered, 4 groups of 24 Hyla hybrid male rabbits from 50 to 90 days of age were fed ad libitum on the above diets. High starch diets decreased the feed intake (g 104.1 vs 111.5 ; P < 0.05 and g 109.8 vs 123.6 ; P < 0.01,...

  7. EFFECTS OF CONCURRENT PREGNANCY AND LACTATION IN RABBIT DOES ON THE GROWTH OF FOLLICLES IN DAUGHTERS' OVARIES

    Fortun-Lamothe, L.; Powers, S.; Collet, A.; Read, K.; Mariana, J.C.
    [EN] The aim of this experiment was to study the effects of concurren! pregnancy and lactation in the mother on follicular development in daughter rabbits. Young females from mothers lactating (group PL) or not (group P) during gestation were sacrificed on days 29 (nPL = np =5), 49 (nPL = np =5) or 70 (nPL = 4, np = 5) and one ovary was taken from each. Follicles were divided into size bands according to their diameter. The P and PL group counts in each band were similar at 29 and 49 days, but at 70 days the number of larger growing follicles (diameter > 241 μm) was...

  8. EFFECT OF BIRTH WEIGHT AND LITTER SIZE ON GROWTH AND MORTALITY IN RABBITS

    Poigner, J.; Szendrõ, Zs.; Lévai, A.; Radnai, I.; Biró-Németh, E.
    [EN] Two experiments were performed with Pannon White rabbits. In the first experiment 50 litters were formed with 6, 8 or 1 O rabbits of different birth weight in equal ratios (n = 380, between 39 and 70g). In the second experiment 60 litters of 6, 8 or 1 O rabbits were formed (n = 456), each litter consisting of rabbits of a single weight group only (small: 39 to 43g; medium: 53 to 56 g; large: 63 to 70 g). With increasing birth weight and decreasing litter size, mortality in the suckling rabbits decreased and daily weight gain of kits and weight of rabbits up to 1...
