  1. Use of VP60 RT-PCR to overcome the limitation of haemagglutination inhibition diagnosis of rabbit viral haemorrhagic disease

    Shakal, M.A.; Khelfa, D.E.-D.G; Salman, O.G.A.; Yousif, A.A.; Salwa, E.-A.A
    Rabbit viral haemorrhagic disease (RVHD) is a highly contagious, highly fatal, peracute and acute viral disease of both wild and domestic rabbits caused by rabbit haemorrhagic disease virus (RHDV). Testing for haemagglutination (HA) activity in processed liver samples is one of the cornerstones for rapid diagnosis of RHDV outbreaks in national rabbitries. However, RHDV isolates exhibiting no HA activity are increasingly being reported. The extent of deviation from classical HA activity patterns for RHDV strains in Egypt has not been investigated. This study compared the HA activity patterns of samples collected from 61 RHDV outbreaks that occurred between 1999 and...

  2. Heterosis, direct and maternal additive effects on rabbit growth and carcass traits from a Canadian experiment

    Ouyed, Abida; Rivest, J.; Brun, Jean Michel
    A total of 479 male and female rabbits from the Californian (CA), American Chinchilla (CH) and New-Zealand White (NZ) breeds and nine crosses between them were used in this experiment. This study aimed to estimate heterosis and direct and maternal additive effects as well as some non genetic effects on rabbit growth and carcass traits in order to identify the most appropriate crossbreeding plan to use for rabbit meat production under Quebec conditions. Each rabbit was identified and weighed individually at weaning (35 d) and at slaughter (63 d). Rabbits were slaughtered after an 18 h fasting period from feed...

  3. Efficacy of an autogenous vaccine against highly virulent "Staphylococcus aureus" infection in rabbits

    Meulemans, G.; Haesebrouck, F.; Lipinska, U.; Duchateau, L.; Hermans, K.
    The efficacy of an autogenous vaccine consisting of a whole cell suspension of formalin killed bacteria in sterile buffered saline against Staphylococcus aureus infections was determined, using a well-established rabbit skin infection model. Thirteen eight-week-old rabbits were vaccinated twice subcutaneously with a two-week interval while ten rabbits were injected twice with sterile buffered saline. Two weeks after the last injection, ten vaccinated and all PBS-injected rabbits were inoculated intradermally with 108 cfu of a S. aureus strain which had been shown to be highly virulent for rabbits. Three vaccinated animals served as negative controls and were intradermally injected with sterile...

  4. Determination of faecal dry matter digestibility two weeks after weaning in twenty five day old weaned rabbits

    Gómez-Conde, M.S.; García, J.; Villamide, M.J; Carabaño, R.
    The aim of this work was to analyse the evolution from 26 to 40 d of age of apparent faecal dry matter digestibility (DMd) in rabbits weaned at 25 d of age to define how to determine nutrient digestibility in the post-weaning period. Fifteen New Zealand ' Californian rabbits from five litters (3 rabbits/litter) weaned at 25 d of age and weighing 602±75g were fed ad libitum a commercial diet containing 20.0% crude protein and 33.5% NDF (on DM basis). Feed intake and faeces excretion were recorded daily from 25 to 40 d of age and DM digestibility determined. Litter...

  5. Characterization of the indoor environment and gas emissions in rabbit farms

    Cambra López, María; Calvet Sanz, Salvador; Estellés Barber, Fernando; Germán-Torres, Antonio
    There is a need to characterize gas concentrations and emissions from rabbit production. A study was conducted in order to determine ammonia, nitrous oxide and carbon dioxide concentrations and emissions in three rabbit farms in the Spanish Mediterranean area. Gas emissions were measured for 187 days in two different production stages (reproductive does and fattening rabbits). Gas concentrations were measured every two hours. Indoor temperature, relative humidity and ventilation flow were measured hourly. As a result, indoor temperature and relative humidity varied throughout the year, following a sinusoidal daily variation pattern. Maximum gas concentrations (14.3 mg/m3 of NH3, 7041 mg/m3...

  6. Changes in behavioural and physiological parameters associated with Taenia pisiformis infection in rabbits (Oryctolagus cuniculus) that may improve early detection of sick rabbits

    Betancourt-Alonso, Miguel-Angel; Orihuela, Agustín; Aguirre, Virginio; Vázquez, Reyes; Flores-Pérez, Fernando-Iván
    The purpose of the present experiment was to describe rabbits' early behavioral responses to illness, and its relation with physiological changes to help improve early detection of infection, particularly those induced by Taenia pisiformis in rabbits. Twenty adult female New Zealand rabbits were randomly allocated in two groups, to determine whether changes in behavior and some physiological parameters can be induced in rabbits after a T. pisiformis infection. Infected animals were orally inoculated with 3,000 eggs of T. pisiformis, while controls only received saline solution. Behavioral activity was recorded daily from 19:00 to 21:00 h starting two days before infection....
