  1. Nutritive value of brewers’ grain and maize silage for fattening rabbits

    Guermah, H.; Maertens, L.; Berchiche, M.
    [EN] Specific knowledge of the nutritive value of raw materials is fundamental to formulate balanced diets for rabbits and allows greater use of by-products and non-conventional feedstuffs. This paper examines the feeding value of sun-dried brewers’ grain and maize silage (whole plant) for fattening rabbits. Twenty-four individually caged 8-wk-old rabbits were used to determine the digestibility. Both wet products were sun-dried and ground before being incorporated into a basal diet. The inclusion level at the expense of all basal ingredients amounted to 30%. Basal diet and both experimental diets were fed ad libitum to 8 rabbits during the 4-d balance...

  2. Effect of diet supplementation with live yeast Saccharomyces cerevisiae on growth performance, caecal ecosystem and health of growing rabbits

    Belhassen, T.; Bonai, A.; Gerencsér, ZS.; Matics, ZS.; Tuboly, T.; Bergaoui, R.; Kovacs, M.
    [EN] The aim of this study was to determine the effect of the live yeast Saccharomyces cerevisiae on the growth performance, caecal ecosystem and overall health of growing rabbits. A control diet was formulated (crude protein: 15.9%; neutral detergent fibre: 31.6%) and another diet obtained by supplementing the control diet with 1 g of Saccharomyces cerevisiae (6.5×109 colony-forming units) per kg of diet. Ninety 35-d old rabbits were allotted into 3 groups: TT (rabbits offered the supplemented diet from 17 d of age onwards), CT (rabbits offered supplemented diet from 35 d) and CC (rabbits fed non-supplemented diet). Body weight...

  3. Effect of Alchornea cordifolia leaf meal inclusion and enzyme supplementation on performance and digestibility of rabbits

    Ayodele, S.O.; Oloruntola, O.D.; Agbede, J.O.
    [EN] A feeding trial was conducted to study the performance, digestibility and health status of weaner rabbits fed diets including Alchornea cordifolia leaf meal (ALM: 18% crude protein [CP] and 12.9% crude fibre) and supplemented with a multi-enzyme additive (cellulase, xylanase, β-glucanase, α-amylase, protease, lipase). Six experimental diets were arranged factorially: 3 levels of ALM (0, 5 and 10% substituting palm kernel cake: 16.3% CP and 39.1% neutral detergent fibre) combined with 2 levels of enzyme supplementation (0 and 0.35 g/kg). One hundred and eighty healthy, 5-wk-old weaner rabbits of cross-breeds were randomly allotted to 6 dietary treatments (30 rabbits/treatment,...

  4. Differential gene expression profiles in foetal skin of Rex rabbits with different wool density

    Liu, L.; Li, B.; Zhu, Y.L.; Wang, C.Y.; Li, F.C.
    [EN] This study investigated the mechanisms controlling hair follicle development in the Rex rabbit. The Agilent rabbit gene expression microarray was used to determine differentially expressed genes in Rex rabbit foetuses with different wool densities. The expression patterns of selected differentially-expressed genes were further investigated by quantitative real-time PCR. Compared to low wool density rabbits, 1342 differentially expressed probes were identified in high wool density rabbits, including 950 upregulated probes and 392 downregulated probes. Gene ontology analysis revealed that the most upregulated differentially expressed probes belonged to receptors and the most downregulated differentially expressed probes belonged to DNA binding molecules....

  5. Correlating single nucleotide polymorphisms in the myostatin gene with performance traits in rabbit

    Abdel-Kafy, E.M.; Darwish, S.F.; ElKhishin, D.
    [EN] The Myostatin (MSTN), or Growth and Differentiation Factor 8 (GDF8), gene has been implicated in the double muscling phenomenon, in which a series of mutations render the gene inactive and unable to properly regulate muscle fibre deposition. Single nucleotide polymorphisms (SNPs) in the MSTN gene have been correlated to production traits, making it a candidate target gene to enhance livestock and fowl productivity. This study aimed to assess any association of three SNPs in the rabbit MSTN gene (c.713T>A in exon 2, c.747+34C>T in intron 2, and c.*194A>G in 3’-untranslated region) and their combinations, with carcass, production and reproductive...

  6. Abstracts of the 41th Symposium on Cuniculture, ASESCU

    [EN] The 41st Congress of the Spanish Association of Cuniculture (ASESCU) was held in Hondarribia (Guipúzcoa province) from 12th to 13th May 2016. This edition coincided with the 40th anniversary of ASESCU, which was founded in 1976. The main papers focussed on analysing the changes in rabbit feeding in the last decades and future prospects, on preparing the future reproductive rabbit, on Spanish consumer segmentation and characterization of rabbit meat consumption, and on the role of the Rabbit Meat Marketing Board (INTERCUN) in promoting consumption of rabbit meat in Spain. A specific session was devoted to explain the objectives and progress of the research projects supported...

  7. Consumer segmentation based on food-related lifestyles and analysis of rabbit meat consumption

    Buitrago Vera, Juan Manuel; Escribá Pérez, Carmen; Baviera Puig, Maria Amparo; Montero-Vicente, L.
    [EN] Market segmentation divides the market into small groups of consumers who share similar characteristics. As all consumers within the same group have a common profile, marketing strategies can be adapted to target a specific type of consumer. Owing to the rapid changes in today’s society, consumer lifestyle has become the ideal criterion for market segmentation. In this study, we employed the food-related lifestyle model, which scholars have shown to be suitable and valid in several countries. Using data from a survey (with 3.53% error), we segmented the Spanish food market based on consumers’ food-related lifestyles. For each segment, we...

  8. Compositional analysis and physicochemical and mechanical testing of tanned rabbit skins

    Souza, M.L. R.; Hoch, A. L.; Gasparino, E.; Scapinello, C.; Mesquita Dourado, D.; Claudino da Silva, S. C.; Lala, B.
    [EN] Chemical composition and physicochemical and mechanical parameters of New Zealand White rabbit tanned skin were evaluated. Skin samples from 70-d-old males, in natura and semi-finished, were collected for evaluation. The in natura treatment comprise skins without any processing, while semi-finished treatment comprise skins after soaking, fleshing, liming, de-liming, purging, degreasing, pickling, tanning, neutralising, re-tanning and dyeing, followed by oiling, drying, stretching and softening. After tanning, samples from the dorsal and flank regions were removed for tensile and physicochemical testing in the longitudinal and transverse directions. A split plot design was used with plot treatments (leather regions: R1=dorsal and R2=flank)...
