  1. The importance of subcutaneous abscess infection by Pasteurella spp. and Staphylococcus aureus as a cause of meat condemnation in slaughtered commercial rabbits

    Ferreira, A.; Monteiro, J.M.; Vieira-Pinto, M.
    [EN] Subcutaneous abscesses are lesions frequently reported in commercial rabbits. Both at farm and slaughterhouse level, these lesions are responsible for economic losses and a potential decrease in meat quality. The present study was devised to identify the main causes of meat condemnation in slaughtered commercial rabbits and assess the importance of abscess lesions in this domain. For these purposes, 281423 rabbits were evaluated during meat inspection at the slaughterhouse. The results achieved showed that subcutaneous abscesses were the major cause of condemnation, being responsible for the rejection of 1355 (0.48%) rabbit carcasses. The main affected area was the hind limbs (31.37%), followed by the cervical area...

  2. Reproduction performances of a synthetic rabbit line and rabbits of of local populations in Algeria, in 2 breeding locations

    Zerrouki, Nacira; Lebas, Francois; Gacem, Malika; Meftah, Ibtissem; Bolet, Gérard
    [EN] The aim of this study was to compare the production of a synthetic line (Syn) of rabbits to that of 2 local Algerian populations (W and Loc). The Syn line was obtained from the crossbreeding of a well adapted local population frequently used in Algerian familial farms (Loc) with a more productive French strain. The W population is maintained by a public cooperative and is used mainly in Kabylia region; it is called “white” because of its albino phenotype. Rabbits were placed under the same experimental conditions in 2 rabbitries of a state technical institute. In Baba Ali (Algiers), 50 does of each genotype...

  3. Pannon breeding program in rabbit at Kaposvár University

    Matics, ZS.; Nagy, I.; Gerencsér, ZS.; Radnai, I.; Gyovai, P.; Donkó, T.; Dalle Zotte, A.; Curik, I.; Szendrő, ZS.
    [EN] In this study, the rabbit breeding programme conducted at the Kaposvár University is extensively discussed. Population history and recorded traits, creation of the different synthetic lines, evolution of their selection criteria,  stimation of the genetic parameters and genetic trends are the main elements described. The programme (Pannon rabbit breeding programme) is operated with 1 maternal line and 2 paternal lines. At present the maternal line (Pannon Ka) is selected for number of kits born alive, while the 2 paternal lines are pre-selected for litter weight (Pannon White) and average daily gain (Pannon terminal line), respectively, then they are both selected for thigh muscle volume (based...

  4. Genetic comparison of milk production and composition in three maternal rabbit lines

    EL Nagar, Ayman Gamal Fawzy; Sánchez, Juan Pablo; Ragab, Mohamed Mohamed; Mínguez Balaguer, Carlos; Baselga Izquierdo, Manuel
    [EN] The aim of this study was to compare 3 Spanish maternal rabbit lines (A, V and LP) in terms of milk production and composition. These lines were founded on different criteria but selected for litter size at weaning. A total of 194 mature does in their third or higher parity were used. The milk yield of does was recorded at 1, 2, 3, 4, 8, 9, 10, 11, 15, 16 and 17 d post-partum (dpp). The milk production traits studied were weekly milk yield (WMY; g/wk) and milk conversion ratio (MCR; grams of litter gain per grams of milk...

  5. Evaluation of calcium superphosphate as an additive to reduce gas emissions from rabbit manure

    Estellés Barber, Fernando; Cambra López, María; Jiménez Belenguer, Ana Isabel; Calvet Sanz, Salvador
    [EN] Techniques to reduce the emission of air pollutants from livestock production are demanded. In this study, the effect of an additive (calcium superphosphate) on gas emissions from rabbit manure was investigated and compared with a control where no additive was used. Calcium superphosphate was applied at a rate of 100 g/m2 per week in a manure pit during 2 cycles of growing rabbits. Manure samples were collected weekly and then chemically and microbiologically analysed. Gas emissions (ammonia, carbon dioxide, methane and nitrous oxide) were determined in 2 open flux chambers. No differences were observed in gas emissions between the treated and control samples...

  6. Cage-enrichment: rabbit does prefer straw or a compressed wooden block

    Rommers, Jorine M.; Bracke, Marc B.M.; Reuvekamp, Berry; Gunnink, Henk; de Jong, Ingrid C.
    [EN] The effect of different food related materials on the behaviour of commercial meat rabbit does was investigated to provide them enrichment. Five different treatments were tested. Control (pens without additional enrichment, C) was compared with pens containing a pinewood stick (Pine), straw in a plastic bin (Straw), a compressed wooden block (Ply) or a combination of straw and a pinewood stick (Straw+Pine). The experiment was conducted on a commercial rabbit farm using 80 cages with multiparous lactating hybrid (Hycole) rabbit does. Behavioural observations were conducted in the first 4 wk of 2 successive lactations of 6 wk each, twice a week from 15:00 to 18:30...

  7. Abstracts of the 39th Symposium on Cuniculture, ASESCU Tudela, Spain, 29 th-30th May, 2014

    [EN] The 39th Congress of the Spanish Association of Cuniculture (ASESCU) was held in Tudela from 29th to 30th of May 2014. The main papers were related to analysing the current situation of rabbit sector in Navarra region, problems related to marketing and opening new markets for rabbit meat, production costs in rabbit farming, producer organisations, growth performance in crossbred rabbits as well as the partnership between the Spanish Institute of Agricultural Research (INIA) and the rabbit marketing board (INTERCUN) to support research projects. In addition, 2 round tables were held on the role of producer associations in the development...
