  1. Effect of light intensities on reproductive performance, nursing behaviour and preference of rabbit does

    Matics, Zs.; Szendrő, Zs.; Radnai, I.; Kasza, R.; Gerencsér, Zs.
    [EN] The aim of the experiment was to compare the reproductive performance and nursing behaviour of rabbit does reared under 2 different light intensities and observe the preference of does among cages with different light intensities. Female rabbits were randomly housed in 2 identical rooms, under the same housing conditions in wire-net cages. The 2 rooms only differed in the light intensity; group L: 150-200 lux (n=54 does, 230 inseminations), group D: 10-20 lux (n=54 does, 232 inseminations). Reproduction data from the first 5 consecutive reproductive cycles were evaluated. Nursing behaviour of the does (n = 24) was observed at...

  2. Dietary supplementation of Digestarom® herbal formulation: effect on apparent digestibility, faecal and caecal microbial counts and live performance of growing rabbits

    Celia, C.; Cullere, M.; Gerencsér, Zs.; Matics, Zs.; Giaccone, V.; Kovács, M.; Bónai, A.; Szendrő, Zs.; Dalle Zotte, A.
    [EN] The experiment aimed to study the effect of Digestarom® dietary inclusion (herbal formulation containing a mixture of essential oils, herbs, spices and extracts) on apparent digestibility and digestive ecosystem of growing rabbits, as well as the effects of its supplementation before and after weaning on growth performance. At kindling, rabbit does and litters were divided into 2 dietary groups (51 does/group) and fed either a control diet (C) or a diet supplemented with 300 mg Digestarom®/kg diet (D) until weaning, which occurred at 35 d (before weaning supplementation). Each group was further divided into 3 dietary groups: CC received...

  3. Effect of increased ovulation rate on embryo and foetal survival as a model for selection by ovulation rate in rabbits

    Badawy, A.Y.; Peiro, R.; Blasco Mateu, Agustín; Santacreu Jerez, María Antonia
    [EN] Selection for ovulation rate in prolific species has not improved litter size, due to an increase in prenatal mortality, with most mortality observed in the foetal period. The aim of this study was to investigate the magnitude and timing of embryo and early foetal survival in females with high ovulation rate using hormonal treatment as a model for selection by ovulation rate. Two groups of females (treated and untreated) were used. Treated females were injected with 50 IU equine chorionic gonadotropin 48 h before mating. Females were slaughtered at 18 d of gestation. Ovulation rate (OR), number of implanted...

  4. Carcass traits and meat quality of growing rabbits in pens with and without different multilevel platforms

    Martino, M.; Mattioli, S.; Farkas, P.; Szendrő, Zs.; Dal Bosco, A.; Ruggeri, S.; Matics, Zs.; Castellini, C.; Gerencsér, Zs.
    [EN] The aim of this trial was to determine the effect of the presence of wire or plastic mesh elevated platforms on carcass traits and meat quality characteristics, with particular attention to the oxidative status of growing rabbits. A total of 174 five-week old rabbits were randomly divided into 3 groups with 2 replications (6 pens; 29 rabbits/pen): pens without platforms (NoP) with a stocking density of 16 rabbits/m2 and pens with wire-mesh platforms (WP) or plastic-mesh platforms (PP) that were placed on 2 levels, with a stocking density of 16 rabbits/m2 on the floor or 9.14 rabbits/m2 when the...

  5. Studying the expression patterns of OCT4 and SOX2 proteins in regenerating rabbit ear tissue

    Javanmard, A. S.; Bahrami, A. R.; Mahmoudi, Z.; Saeinasab, M.; Mahdavi-Shahri, N.; Matin, M.M.
    [EN] Epimorphic regeneration in New Zealand rabbit ear is an interesting example of mammalian wound healing in which blastema formation is involved in replacement of injured tissues. It has been suggested that isolated cells from regenerating rabbit ear possess stem-like properties. In this study, we aimed to determine the expression of stemness markers, OCT4 and SOX2 proteins, in regenerating rabbit tissues by immunohistochemistry. Results indicated that both proteins could be detected in epithelial cells, hair follicle cells and perichondrium cells. Expression pattern analysis of OCT4 and SOX2 proteins showed no clear differences between regenerative and non-regenerative control tissues. According to...

  6. Meat physical quality and muscle fibre properties of rabbit meat as affected by the sire breed, season, parity order and gender in an organic production system

    Dalle Zotte, A.; Cullere, M.; Rémignon, H.; Alberghini, L.; Paci, G.
    [EN] The aim of the study was to evaluate some meat physical quality and muscle fibre properties of rabbit meat when considering 2 sire breeds (SB: Vienna Blue [VB]; Burgundy Fawn [BF]; both coloured and slow-growing breeds), several parity orders (P: 1, 2, ≥3), gender (G), and 2 slaughter seasons (SS: spring, summer) in an organic production system. The effect of storage time (ST) at frozen state (2 mo at –20°C) of Longissimus lumborum (LL) meat was also evaluated. Animals were slaughtered when they reached 2.8 kg of live weight. Then, pH and L*a*b* colour values of Biceps femoris (BF)...

  7. Effects of plant extracts and essential oils as feed supplements on quality and microbial traits of rabbit meat

    Kone, A. P.; Cinq-Mars, D.; Desjardins, Y.; Guay, F.; Gosselin, A.; Saucier, L.
    [EN] The effects of dietary supplementation of onion, cranberry,  strawberry and essentials oils on meat quality were analysed. Five groups of 48 Grimaud female weaned rabbits received the supplemented or the control ration; the experimental unit was a cage of 6 rabbits. Each experimental diet contained 10 ppm of added active ingredients.  Rabbits were fed with the experimental diets for 4 wk before determining slaughter and carcass traits and determining the pH at 1 and 24 h post mortem (pHu) of the Longissimus dorsi (LD) and the Biceps femoris (BF) muscle, left and right, respectively. Cooking loss, drip loss and...

  8. Effect of turmeric powder (Curcuma longa L.) and ascorbic acid on antioxidant capacity and oxidative status in rabbit burgers after cooking

    Mancini, S.; Preziuso, G.; Paci, G.
    [EN] The aim of this study was to evaluate the effects of turmeric powder and ascorbic acid on lipid oxidation and antioxidant capacity in cooked rabbit burgers. The burgers were derived from 3 different formulations (C, control, with no additives; Tu with 3.5% of turmeric powder and AA with 0.1% of ascorbic acid) and were stored at 4°C for 0 and 7 d and cooked. The lipid oxidation (thiobarbituric acid reactive substances [TBARS]) and antioxidant capacity (2,2-azinobis-[3 ethylbenzothiazoline-6-sulfonic acid] {ABTS}, 1,1-diphenyl-2-pircydrazyl [DPPH] and ferric reducing ability [FRAP]) were evaluated. A significant interaction between storage time and formulation (P<0.001) was observed...
