  1. Technical note: Characterization of key volatile odorants in rabbit meat using gas chromatography mass spectrometry with simultaneous distillation extraction

    Xie, Y.J.; He, Z.F.; Zhang, E.; Li, H.J.
    [EN] This study explored the key volatile compounds in both male and female rabbit meat. Simultaneous distillation extraction with dichloromethane was adopted to extract the volatile compounds in Hyla rabbit meat. A total of 35 volatile compounds were identified by gas chromatography–mass spectrometry and quantified with 2, 4, 6-thimethylpyridine as internal standard. Seventeen volatile aldehydes, 4 alcohols, 2 ketones, 2 acids, 1 heterocyclic compound, 2 alkanes and 7 esters were detected. Hexanal, heptanal, octanal, nonanal, (E, E)-2, 4-decadienal, 1-octen-3-ol and (Z)-2-decenal were the key odorant compounds, with high relative odour activity value. Furthermore, the concentration of volatile compounds in male...

  2. Short communication: Absence of campylobacter spp. In intensive rabbit farming in eastern Spain, preliminary results

    Marín, C.; Soto, V.; Marco Jiménez, Francisco
    [EN] Campylobacteriosis and salmonellosis are the most frequently reported zoonoses and among the most common causes of diarrhoeal illness in the European Union and the United States, and their incidence appears to be increasing. Campylobacter species are routinely found in poultry, swine, cattle, dairy cows and sheep. So far, there are few descriptions of Campylobacter isolation from rabbits. Rabbit meat is a common item in the Mediterranean diet. In this context, the aim of the present study was to investigate the occurrence of Campylobacter spp. in healthy rabbits reared in intensive farms in the Alto Palancia region, eastern Spain. Caecal...

  4. Performance and sustainability of two alternative rabbit breeding systems

    Theau.Clément, M.; Guardia, S.; Davoust, C.; Galliot, P.; Souchet, C.; Bignon, L.; Fortun-Lamothe, L.
    [EN] The aim of this study was to evaluate 2 alternative breeding systems that differ from the current system in terms of reproduction rhythm, age of females at first insemination and the age of kits at weaning and at slaughter. We measured the performance of 332 females and their offspring over 4 consecutive cycles, as well as the sustainability of the systems. We compared an intensive (group I: reproduction rhythm [RR]=35 d; first insemination [AI1]=20.6 wk of age; weaning age [WA]=32 d; slaughter age [WS]=63 d) an extensive (group E: RR=49 d; AI1=16.6 wk; WA=30 d; WS=70 d) and a...

  5. Ovulation rate and early embryonic survival rate in female rabbits of a synthetic line and a local Algerian population

    Belabbas, R.; García, M.L.; AinBaziz, H.; Berbar, A.; Zitouni, G.; Lafri, M.; Bouzouan, M.; Merrouche, R.; Ismail, D.; Boumahdi, Z.; Benali, N.; Argente, M.J.
    [EN] A higher litter size at birth has been reported in female rabbits from a Synthetic line than in those of the Local Algerian population. The aim of this work was to analyse whether this difference in litter size was due to a higher ovulation rate and/or embryonic survival rate in Synthetic line than in Local Algerian population. In total, 24 multiparous female rabbits from Synthetic line and 23 from Local population were used in this experiment. Litter size at birth was recorded up to the first 3 parities. Litter size was 20% higher in Synthetic line than Local population....

  6. Immune responses induced in rabbits after oral administration of bovine serum albumin in combination with different adjuvants (herb extracts, aluminium hydroxide and platinum nanoparticles)

    Bižanov, G.; Ramanavičienė, A.; Normantienė, T.; Jonauskienė, I.
    [EN] The aim of the current study was to evaluate the immunostimulatory activity of 10 different herbal extracts from Vitex agnus-castus, Vinca major, Aloe arborescens and the polyherbal product containing extracts from Sambucus nigra, Primula versis, Pinus alba, Gentiana lutea, Cetraria islandica, Eucaliptus globulus, Citrus limon and aluminium hydroxide, as well as platinum nanoparticles. Rabbits were immunized three times orally with bovine serum albumin (BSA) in combination with the components mentioned above. BSA-specific IgA antibodies in saliva and IgG antibodies in serum were examined by ELISA. It was found that the rabbits immunized with BSA in combination with either platinum...

  7. Fattening rabbits in mobile arks: effect of housing system on in vivo oxidative status and meat quality

    Mattioli, S.; Martino, M.; Ruggeri, S.; Roscini, V.; Moscati, L.; Dal Bosco, A.; Castellini, C.
    [EN] The aim of this trial was to study the effect of an alternative housing system on the oxidative status and meat quality of fattening rabbits. From May to June 2014, 60 rabbits of 35 d of age were reared in Mobile Arks (MA) placed on alfalfa grass and frequently moved for 40 d. To assess the health status of animals, blood samples were collected at slaughter in MA and in conventional cages (C). Meat quality parameters were also evaluated. Concerning the in vivo oxidative status, ark-reared rabbits showed higher thiobarbituric reactive substances values than C ones, probably for the...

  8. Digestion, growth performance and caecal fermentation in growing rabbits fed diets containing foliage of browse trees

    Abu Hafsa, S.H.; Salem, A.Z.M.; Hassan, A.A.; Kholif, A.E.; Elghandour, M.M.Y.; Barbabosa, A.; Lopez, S.
    [EN] This study aimed to evaluate the effect of feeding dried foliage (leaves and petioles) of Acacia saligna, Leucaena leucocephala or Moringa oleifera on the performance, digestibility, N utilisation, caecal fermentation and microbial profiles in New Zealand White (NZW) rabbits. One hundred weaned male NZW rabbits weighing 819.2±16.6 g and aged 35±1 d were randomly allocated into 4 groups of 25 rabbits each. Rabbits were fed on pelleted diets containing 70% concentrate mixture and 30% Egyptian berseem (Trifolium alexandrinum) hay (Control diet) or one of the other 3 experimental diets, where 50% of berseem hay was replaced with A. saligna...

  9. Development and establishment of a protocol of an individual aggressiveness test in breeding does

    Olivas, I.; Simarro, L.; Villagrá, A.
    [EN] The present work aims to define the optimal conditions to perform a resident-intruder test in individually housed breeding does as a measure of aggressiveness and describe the biological characteristics of aggressiveness in rabbit does: severity, frequency, duration and latency of aggressive events. Sixty-four nulliparous does at 90 d of age were used for this experiment, half (32 does) as residents and the rest as intruders, testing them once a week for 14 wk. The time and duration of each aggressive behaviour was recorded and analysed to assess the aforementioned measures. According to the results, and regarding the studied effects,...

  11. Adaptive capacity of female rabbits submitted to a change in breeding practices

    Theau.Clément, M.; Galliot, P.; Souchet, C.; Bignon, L.; Fortun-Lamothe, L.
    [EN] The aim of this study was to test the consequences of a change in breeding practices on 219 multiparous rabbit does over 2 reproductive cycles (5th and 6th insemination). Three rabbit breeding systems were defined I: intensive, S: semi-intensive and E: extensive), which varied for the females in terms of reproductive rhythm (RR: 35, 42 and 49 d, respectively) and age at first insemination (20.6, 19.6 and 16.6 wk, respectively), and for kits in terms of age at weaning (32, 35 and 30 d, respectively) and age at slaughter (63, 70 and 70 d, respectively). Females were submitted to...
