  1. Sodium butyrate in growing and fattening diets for early-weaned rabbits

    Ribeiro, Joana; Gaspar, Sandra; Pinho, Mário; Freire, João P. B.; Falcão-e-Cunha, Luisa
    [EN] To study the effect of adding coated sodium butyrate (SB) to growing-fattening rabbit diets, 2 trials were conducted. In trial 1, 180 rabbits were housed in pairs and fattened from 23 (weaning) to 63 d of age to evaluate their zootechnical performance. Trial 2 involved 30 rabbits, from 23 to 37 d of age and housed individually in digestibility cages, to evaluate digestibility, caecal fermentative activity and morphology of the intestinal mucosa. In both trials rabbits were randomly divided into 2 groups, each receiving one of the following diets: control diet [CTR, 360 g neutral detergent fibre (NDF) and...

  2. Nutritive value of sun-dried Pueraria Phaseoloides for rabbits under tropical conditions

    Akoutey, A.; Kpodekon, Marc T.; Bannelier, Carolle; Gidenne, Thierry
    The nutritive value of Pueraria phaseoloides (whole plant, full fruit stage, sun-dried) for the growing rabbit was studied by comparing diets containing an increasing incorporation of Pueraria (0 to 40%) in substitution to a basal mixture. The crude protein (CP) concentration of Pueraria was 17.6 % dry matter (DM), while neutral detergent fibre (NDF) and acid detergent fibre were 51 and 39%, respectively. A basal diet was formulated (51.1% NDF and 19.9% CP, on DM basis) and pelleted. Another 2 diets were obtained through substitution of 20 and 40% of basal diet by Pueraria. Faecal digestibility was measured between 42...

  3. Normal values of haematological and some biochemical parameters in serum and urine of New Zealand White rabbits

    Özkan, Cumali; Kaya, Abdullah; Akgül, Yakup
    [EN] The purpose of the present study was to define the normal haematologic values and some biochemical parameters in serum and in urine in both male and female New Zealand white rabbits and to determine the effect of gender on these parameters. Blood and urine samples from a total of 40 New Zealand white rabbits were investigated. The haematologic parameters were determined in whole blood samples, while serum and urine (urine protein, glucose, creatinine, urea, GGT, nitrite, Na, K, Cl, creatinine clearance) biochemical parameters were determined in serum and urine samples. Normal values of these parameters were determined and statistical...

  4. Morphology, chemical composition, and bacterial concentration of airborne particulate matter in rabbit farms

    Adell Sales, Elisa; Estellés Barber, Fernando; Torres, Antonio G.; Cambra López, María
    [EN] Livestock houses are major sources of airborne particulate matter (PM), which can originate from manure, feed, feathers, skin and bedding and may contain and transport microorganisms. Improved knowledge of particle size, morphology, chemical and microbiological composition of PM in livestock houses can help identify major sources of PM and contribute to the development of appropriate source- specific reduction techniques. In rabbit production systems, however, there is limited information on specific particle characteristics. The objective of this study was to characterise airborne PM in rabbit farms in terms of morphology, chemical compositions and bacterial concentration in different size fractions. Size-fractioned PM...

  5. Description of nestbox visits and suckling events in a group housing system for rabbit does as compared to individual cages

    Rommers, Jorine M.; Kemp, Bas; Houwers, H.W.; Gunnink, Henk; de Jong, Ingrid C.
    Research was conducted to study nursing associated events of lactating rabbit does. Nest box visits and suckling events were investigated using 6 group pens (8 does/pen) and 12 enriched individual cages. Each group pen and individual cage was observed by video for one day per week until weaning at 35 d of lactation, with exception of the third week of lactation. In the first 2 wk of lactation, videotapes were analysed for the frequency and duration of nest box visits per day. The fourth and fifth week of lactation, suckling events on the floor of the group pens and nest...

  6. Characteristics of Staphylococcus aureus isolated from acute, sub-acute and sub-clinical staphylococcosis in rabbits

    Tirpude, Rajeshkumar J.; Batra, H.V.
    [EN] Staphylococcus aureus bacteria isolated from different clinical presentations of staphylococcosis in rabbits were examined for the production of various virulence factors using biochemical and immunological tests. In the total of 106 S. aureus isolates; toxic shock syndrome toxin-1, staphylococcal enterotoxin-C, DNase, ¿-haemolysin, ß-haemolysin, ¿-haemolysin, protein A and clumping factor were observed with a frequency of 33.2, 16.98, 83.96, 69.81, 36.79, 100, 78.30 and 54.72 percent, respectively. No SE-A, SE-B and SE-D producing isolates were recovered in this study. All the S. aureus isolates from acute staphylococcosis produced TSST-1, SE-C and protein A. While ¿¿haemolysin and clumping factor were not...

  7. Activity of diclazuril against coccidiosis in growing rabbits: experimental and field experiences

    Vereecken, Monita; Lavazza, A.; De Gussem, K.; Chiari, M.; Tittarelli, C.; Zuffellato, A.; Maertens, Luc
    [EN] The efficacy of diclazuril in growing rabbits was investigated under experimental and field conditions. In a first experimental trial, the susceptibility of recent isolated French Eimeria field strains to in-feed use of diclazuril, salinomycin and robenidine was studied in fattening rabbits. Rabbits were challenged at the age of 31 d with a mixed inoculum of Eimeria magna, E. media and E. perforans. Production data and oocyst excretion were compared with an infected-untreated control group and an uninfected-untreated control group. Infection resulted in significantly lower production data and higher oocyst excretion in the infected-untreated control group. Salinomycin and diclazuril treated...
