  1. The influence of porcine cathelicidins on neutrophils isolated from rabbits in the course of bone graft implantation

    Wessely-Szponder, J.; Szponder, T.; Bobowiec, R.; Smolira, A.
    [EN] Antimicrobial peptides are important elements of host defence because of their direct antimicrobial activity and modulatory role in innate immune response. The purpose of the study was to determine whether porcine peptides PR-39, protegrins (PGs) and low molecular weight extract (LMWE) are able to influence the neutrophil response during bone graft implantation in rabbits. The study was conducted on 10 White New Zealand rabbits and neutrophil activity was assayed on the basis of elastase, myeloperoxidase, and alkaline phosphatase release as well as free radical generation. Our study showed that PR-39 and PGs inhibited enzyme release from neutrophils except for...

  2. Resources allocation in reproductive rabbit does: a review of feeding and genetic strategies for suitable performance

    Pascual Amorós, Juan José; Savietto, Davi; Cervera Fras, Mª Concepción; Baselga Izquierdo, Manuel
    [EN] This article reviews how frequent feeding and selection programmes can affect resource allocation in rabbit does during reproduction. The consequences of these programmes and the central role of body condition for suitable female performance are analysed considering genetic level, health and welfare. Future reproductive potential of reproductive rabbit females is decided before first partum. There is enough evidence of a possible threshold for the rabbit female birth weight to reach the beginning of reproductive life in a suitable body condition to maximise their future reproductive potential. The moment of first mating could be identified as the last of the...

  3. Reproductive performance of different breeds of broiler rabbits under sub-temperate climatic conditions

    Kumar, D.; Risam, K.S.; Bhatt, R.S.; Singh, U.
    [EN] This study was conducted to assess the effect of breed, season, age and weight of doe at mating on reproductive performance of 4 broiler rabbit breeds, Grey Giant, White Giant, Soviet Chinchilla, and New Zealand White, reared under standard management practices in sub-temperate climatic conditions of India. They were first mated at 6 to 7 mo of age, whereupon an extensive breeding system (re-mating after weaning) was followed. Weaning was done 42 d after kindling. The data from the records on reproduction consisting of 503 matings and 377 kindlings were analysed. The parameters considered were fertility rate, litter size...

  4. Oestrus induction in primiparous lactating rabbits by a 48 hours mother-litter separation: endocrine and behavioural responses

    Ilès, I.; Benazzoug, Y.; Messili, A.; Boukhari, S.; Boiti, C.
    [EN] Primiparous does express low mating acceptance during lactation and different oestrus induction methods are employed to improve sexual receptivity. The aim of this work was to study the effect of a biostimulation, a 48 h doe-litter separation (DLS), in primiparous lactating rabbits on mating acceptance, external characteristics of the vulva and plasma concentrations of estradiol, testosterone, progesterone and cortisol. Seventy primiparous does from local population were divided on day 1 after kindling into 2 equal groups: control (C, n=35), where does always had free access to the nest-box, and DLS (n=35), where free suckling was adopted, except from day...

  5. Impact of rearing mangement on health in domestic rabbits: a review

    Schlolaut, Wolfgang; Hudson, Robyn; Rödel, H.G.
    [EN] High mortality in rearing of domestic rabbits is not only an economic problem but also an animal welfare issue. Among the reasons for this high mortality are some common rearing practices. In this review, we point out several commonly used management practices, which neither represent adequate housing conditions according to the animals' behavioural requirements nor correspond to their nutritional needs. Sometimes, the doe has to build the nursery nest on the cage floor or in a box with a permanently open entrance, often not protected from the light. This can lead to perinatal mortality due to disturbed behaviour of the...

  6. Gnawing blocks as cage enrichment and dietary supplement for does and fatteners: intake, performance and behaviour

    Maertens, Luc; Buijs, Stephanie; Davoust, Chantal
    [EN] The aim of this study was to evaluate different experimental gnawing blocks as cage enrichment in rabbits. One hundred and five pregnant rabbit does housed in conventional wire cages were distributed according to their parity number in 4 homogenous treatment groups. Throughout one complete reproductive cycle (from day 18 of pregnancy till weaning of the litter), does either received no enrichment (controls) or a gnawing block hung from a wire on the cage wall. The 3 different blocks had the same basal components (wheat, molasses and oligoelements), but additionally wood mash (WM), wood mash+chicory pulp (ChP) or wood mash...

  7. Factors affecting wild rabbit production in extensive breeding enclosures: how can we optimise efforts?

    Guerrero-Casado, José; Ruiz-Aizpurua, Leire; Carpio, Antonio J.; Tortosa, Francisco S.
    [EN] The declining rabbit population in the Iberian Peninsula has led hunters and authorities to rear rabbits in captivity systems for their subsequent release. One alternative method to intensive rabbitry systems is the use of extensive breeding enclosures, since they produce animals of greater quality for hunting and conservation purposes. However, some of the factors that affect rabbit production in breeding enclosures are still unknown. The present study used partial least squares regression (PLSR) to analyse the effects of plot size, scrub cover, slope, initial rabbit abundance, the resources needed to dig warrens, predation and proximity to other enclosures on...

  9. Abstracts of 38th Symposium on Cuniculture, ASESCU.


    [EN] The 38th Congress of the Spanish Association of Cuniculture (ASESCU) was held in Zamora from 30th to 31st of May 2013. This edition was mainly devoted to analysing the current situation of production costs in rabbit farming, processing of rabbit meat and new aspects in relation to rabbit diseases. The main papers were related to economic weights in rabbit meat production and production costs in terms of productivity, the cost of feed ingredients, new trends in rabbit meat processing, crossbreds in rabbit farming, hygiene on industrial rabbit farms, feed restriction and de-medicalisation and the new rabbit haemorrhagic disease, as...
