Recent research in rabbit farming has focused on studying the impact of proper nutrition on rabbits during the growing stage. This is done in a proposal to find an effective strategy to reduce health problems in animals during weaning, while also considering the technical and economic aspects of this type of farming. Our study aims to clarify the effects of different types and quantities of dietary restriction on rabbits and their performance, based on various studies and research that have addressed this topic. Therefore, this research serves as a comprehensive summary of previous studies on dietary restriction in rabbits during the fattening stage. The results of these studies demonstrate the effectiveness of dietary restriction as a strategy, which can be adopted to achieve the desired economic goals of markets and consumers, as well as health-related objectives and overall profitability in rabbit farming projects.

L’objectif de cet essai a été d’analyser l’intérêt d’utiliser des aliments disponibles localement en alimentation cunicole, comme le foin de luzerne et la paille de blé, pour remplacer la luzerne déshydratée importée en Algérie. Deux aliments ont été formulés avec, comme principale source de fibres, du foin de luzerne seul pour l’un (F, 40,1 %), combiné avec de la paille de blé pour l’autre (F+P, 17 % foin + 14 % paille). Au sevrage (35 jours), 154 lapins de la souche synthétique ITELV 2006 ont été répartis en trois groupes de poids vifs identiques et logés dans des cages collectives (2–4 lapins/cage) jusqu’à l’âge d’abattage (84 j). Ils ont reçu ad libitum l’un des deux régimes expérimentaux (F ou F+P) ou un régime commercial utilisé comme témoin (Tém). La viabilité des lapins F a été meilleure (90 % ; + 22 points de pourcentage) que celle des lapins Tém (68 %) (p = 0,025) et la viabilité des lapins F+P a été intermédiaire (79,6 % ; + 12 points de pourcentage). Le gain de poids et la consommation d’aliment ont été de 14 % et 30 % plus élevés (p

L’objectif de l’étude a été de caractériser les performances reproductives (fertilité, prolificité, mortalités) et pondérales des lapines de la souche synthétique algérienne « ITELV 2006 », conduites en insémination artificielle (IA) avec un rythme semi-intensif (intervalle mise bas – IA de 12 jours). Durant deux années consécutives (2017 et 2018), un suivi de la conduite de reproduction de 73 lapines, faisant l’objet de 327 IA, a été mené à l’animalerie de l’Université de Chlef (Algérie). Durant la durée de l’étude, les IA ont été réalisées à partir d’une semence récoltée chez des mâles du même type génétique et analysée localement. Les données relatives à l’IA, à la palpation, à la mise bas et au sevrage ont été enregistrées pour l’ensemble des femelles. L’effet de la saison sur les critères de poids et les performances de reproduction des lapins a été analysé. Toutes les données ont été soumises à une analyse de variance. Les femelles ont montré une bonne prolificité de 9,5 ± 2,4 nés totaux dont 8,4 ± 2,9 nés vivants par mise bas et 7,4 ± 2,6 sevrés par sevrage, avec des taux de fertilité de 85,6 ± 35,1 % à la palpation et 69,7 ± 45,9 % à la mise bas. Le poids adulte des femelles à l’IA était de 3584 ± 391 g. Le lapereau pesait en moyenne 63 ± 13 g à la naissance et 490 ± 81 g au sevrage. Un effet très significatif de la saison a été enregistré sur la fertilité et la prolificité des lapines, et sur le poids et la mortinatalité des lapereaux avec les plus faibles valeurs enregistrées en saison chaude (63 % de fertilité). Cependant, les femelles sont restées productives durant cette période de grande chaleur.

Cent vingt-neuf lapines de population locale algérienne de première parité ont été utilisées dans la présente étude à la ferme expérimentale de l'université de Batna 1. Les animaux ont été divisés en quatre groupes égaux comportant 30 sujets (femelle vide, femelle gestant, femelle gestant et allaitante et femelle en lactation seulement). L'accouplement naturel a été utilisé, les lapereaux ont été sevrés à 28 jours. Quatre échantillons de sang ont été prélevés sur des femelles à différents stades physiologiques. L’état physiologique a eu une incidence importante (p < 0,05) sur le BCS cumulé, la production laitière, la taille de la portée et le poids de la portée à la naissance. Les concentrations de protéines totales, albumine, globuline, acide urique et créatinine ainsi que les taux de T3 et de progestérone étaient plus élevés (p < 0,05) chez le groupe PL (5,70 ± 1 g / dl, 2,98 ± 0,07 g / dl, 1,88 ± 0,06 g / dl, 34,9 ± 3,4 mg / dl, 1,3 ± 0,4 mg / dl, 44,3 ± 0,93 ng / dl, 18,98 ± 1,5 ng / ml) respectivement. L'état physiologique a augmenté de manière significative (p < 0,05) les lipides totaux, les triglycérides et le cholestérol total dans les dosages des groupes P, P-L et L par rapport à leurs concentrations dans le groupe E. L'état physiologique de l'alanine aminotransférase (ALT), de l'aspartate aminotransférase (AST) et de la phosphatase alcaline a été affecté pendant la grossesse et la période d'allaitement (5,65 ± 0,1 UI / L, 22 ± 1,3 UI / L vs 5,45 ± 0,22, 20,35 ± 4,3 UI / L). Les groupes P, P-L et L’ont des taux de leptine plus élevés (p < 0,05). Les concentrations d'insuline et de glucose ont augmenté dans les groupes P et P-L par rapport aux groupes E et L.

Burn animal models provide substantial insights into burn pathophysiology. Choice of the apt model is important for determining the clinical efficacy of new medicines. Therefore, standardization of burn models is crucial for scientific research. Use of common techniques like hot water, electricity and incandescent instruments to generate animal burn models is widely reported. However, great discrepancy in employed temperature and exposure times demands user-dependent standardization of the animal model prior to research. Establishment of custom generated in vivo burn models giving consideration to reduced use, suffering and risk of the experimental animal is equally crucial. Accordingly, this pilot study demonstrates a novel approach using rabbit and porcine cadaver skin for standardization of burn parameters prior to use in live animal models. Using a custom-made soldering iron coupled to a 16cm2 surface area copper plate, burns at randomly chosen temperatures of 80ËšC and 120ËšC, with exposure times ranging from 60s to 180s, were produced on rabbit and porcine cadaver skins. On gross and histopathological analysis, parameters required to generate characteristic changes for deep partial and full thickness burn involvement were established. The identified temperature and exposure time parameters were further validated in live animal models. In vivo validation established the success of this approach, highlighting reduced animal use, ease, reproducibility and efficacy in burn model standardization. The findings of this study will hopefully encourage researchers to opt for cadaver skin to determine parameters required to generate a specific degree of burn prior to its use in live animals for burn research.

Euphorbia heterophylla est une adventice dont les feuilles et les tiges peuvent constituer 70 % de l’alimentation des lapins (Oryctolagus cuniculus L.). Par ailleurs, sa teneur en acide-linolénique (ALA, C18:3 n-3) (56 % des acides gras totaux) est proche de celle du lin (Linum usitatissimum). Afin de contribuer à un meilleur équilibre nutritionnel des populations, l’effet de la durée de la supplémentation d’un régime alimentaire à base de granulé (MOD0) par les feuilles et les tiges de cette adventice sur les teneurs en acide linoléique (LA, C18:2 n-6) et en ALA des muscles semimembranosus, longissimus dorsi et du tissu adipeux périrénal des lapins en croissance a été étudié. Le régime témoin (MOD0) a été supplémenté par 50 % de matière sèche d’euphorbe de la naissance a trois mois d’âge (MOD90) ou par 50 % de matière sèche d’euphorbe seulement durant un mois entre 61 et 91 jours d’âge (MOD30). Les ratios LA/ALA étaient de 9,8, 2,1 et 1,5 dans le muscle semimembranosus, de 11,8, 4,6 et 2,1 dans le longissimus dorsi, et de 8,6, 2,0 et 1,0 dans le tissu adipeux perirenal, respectivement pour MOD0, MOD30 et MOD90 (p < 0,001). La durée de la supplémentation d’au moins 30 jours par l’euphorbe a eu un impact positif sur les ratios LA/ALA qui ont été conformes à la recommandation internationale (≤ 5) pour la nutrition humaine. En conclusion, la supplémentation appropriée des régimes de lapins par l’euphorbe, dans les régions ou elle abonde, sera bénéfique pour la santé humaine.

We present a new algorithm for solving the LPN problem. The algorithm has a similar form as some previous methods, but includes a new key step that makes use of approximations of random words to a nearest codeword in a linear code. It outperforms previous methods for many parameter choices. In particular, we can now solve the (512 , 1 8) LPN instance with complexity less than 2 80 operations in expectation, indicating that cryptographic schemes like HB variants and LPN-C should increase their parameter size for 80-bit security.

The aim of this work is to evaluate the protective effect of palm pollen grains (phoenix dactylifera L (DPP)) against the toxicity of, (DEP) which is one of the elements having a toxic effect on organisms living. The study was conducted on New Zealand adult male rabbits for 30 days. The animals were divided into four groups. Group I received distilled water and was taken as a control, while Groups II, III and IV received daily 240 mg / kg / day of (DPP), 330 ml / kg / day of (DEP) and an association of 330ml / kg / day of (DEP) with 240 mg / kg / day of (DPP), respectively. After treatment, the rabbits were sacrificed and the organs were removed, fixed in 10% formalin and stained with hematoxylin and eosin. The blood was collected in tubes to evaluate different biochemical and hematological parameters. The results indicate that treatment with (DEP) caused a decrease in body weight and thymus weight, as well as a drop in white blood cell count and percentage of granulocytes and an increase in lymphocytes compared to the control group. The administration of palm pollen seeds (DPP) showed a positive improvement in all parameters studied. Our results confirm that DEP can effect changes in immune function and, therefore, show that DPP treatment can mitigate the deleterious effects of DEP. [ABSTRACT FROM AUTHOR]

The objective of this study is to evaluate the impact of organic extracts of Bunium incrassatum seeds (Talghouda) on the evolution of some hematological parameters. The study was conducted on rabbits of the local population Oryctolagus cuniculus) the animals were divided into five groups and given daily orally at doses of 0.25, 50, 100 and 200 mg/kg/day. Dose 0 was taken as a control. After treatment, the rabbits were sacrificed, the organs were removed and fixed in 10% formalin and then stained with hematoxylin and eosin and the blood was collected in two tubes, one containing anticoagulant EDTA, and the other dry for the measurement of the different parameters. The obtained results show that treatment with the organic extract of Bunium incrassatum induced an increase in the body weight of treated rabbits compared to the control, as well as effects on the hematological parameters, characterized mainly by a significant increase in the rate of lymphocytes, hemoglobin. This result coincides with the increase in the relative weight of the kidney and liver target organs. We conclude that the components of this medicinal plant may, at specific doses, have a positive effect on certain hematological parameters. [ABSTRACT FROM AUTHOR]

Introduction: A large variety of pet feeds is commercially available for pet herbivores; these feeds may differ in nutrient composition from the natural diet, and may trigger different feeding behaviours than observed in natural habitats. Here, we surveyed literature on the natural diet and activity budget of rabbits (Oryctolagus cuniculus), guinea pigs (Cavia porcellus), chinchilla (Chinchilla lanigera) and degus (Octodon degus), as well as 260 compound feeds commercially available for these species between 1982 and 2020. The species are classified as herbivores, with available data on natural diets suggesting a crude fibre (CF) level of approximately 250 g/kg dry matter (DM), natural feeding activity at a magnitude of 4-7 h per day, with distinctively shorter feeding when fed on compound pet feeds. Only for a minority of feeds did the first 5 listed ingredients not include a starchy ingredient, or only ingredients not considered suitable for human consumption. The percentage of feeds whose CF level was less than 150 g/kg DM was 22 % for production rabbits, 18 % for pet rabbits, 26 % for guinea pigs, 18 % for chinchillas and 14 % for degus; in other words, a majority of currently marketed products have CF levels in accord with published recommendations, even if that means a discrepancy to natural diets. Screening the producers' feeding instructions suggests they should generally not be followed uncritically. No temporal trends in the CF levels of these diets was evident. There is no consensus whether only products resembling natural diet items should be included in pet feeds, or whether vegetable byproducts not edible by humans should also be included. The observed practice of pet feed composition largely did not follow either concept, questioning the general rationale of pet feed composition. Whole forage like hay is recommended as the main diet component for these species, and 76 % of pet feed products noted that hay should be fed in the feeding instructions.

One hundred and forty-four young rabbits were used from weaning (34-36 days old) to study growth, feed efficiency and viability in relation to the diet presentation: pelleted or as a flour. The experiment was carried out in three farms (CECURI, GAVA and AHINADJE), with 48 young rabbits in each farm, divided into two groups of 24 animals: an experimental group fed a pellet diet and a control group fed the same diet but in a flour form. Weights and feed intake were measured weekly during the eight-week fattening period, and mortality was checked daily. During fattening (56 days), the young rabbits fed the pelleted diet had a higher (P < 0.001) growth rate (24 g/d) than those fed the flour diet (22 g/d). During the first four weeks, the pelleted diet was more consumed (+ 18%), less rejected (- 77%), with a lower consumption index (- 20%) than the flour diet (P < 0.001). The consumption index (5.2) and feed intake (92 g) were similar during the last four weeks (P > 0.05). On the other hand, the pelleted diet was less rejected (P < 0.001) than the flour diet (1 g vs 4 g). Finally, the mortality rate was lower (15.28 %) in the groups of young rabbits that received the pelleted diet than in those that received the flour diet (46%).

The learning parity with noise (LPN) problem has recently proved to be of great importance in cryptology. A special and very useful case is the Ring-LPN problem, which typically provides improved efficiency in the constructed cryptographic primitive. We present a new algorithm for solving the Ring-LPN problem in the case when the polynomial used is reducible. It greatly outperforms the previous algorithms for solving this problem. Using the algorithm, we can break the Lapin authentication protocol for the proposed instance using a reducible polynomial, in \sim 2^71 bit operations. [ABSTRACT FROM PUBLISHER]

The objective of this experiment was to determine whether changing the dietary neutral detergent fiber (NDF)/starch ratio affected caecal microbiota when 4 different diets (diet A: 2.3 NDF/starch, diet B: 1.9, diet C: 1.4, diet D: 1.0) were formulated. A total of 200 weaned rabbits (35 days old, 50 per group) were used for the experiment, which started after an adaptation period of 7 days (i.e., day 42). Caecal contents were obtained from rabbits fed different NDF/starch diets at 52, 62, 72, and 82 days of life. The bacterial community structure was characterized by high-throughput 16S rRNA sequencing. Firmicutes, Actinobacteria, Synergistetes, and Tenericutes did not significantly change with diet or age. However, Bacteroidetes ( P < 0.05), Proteobacteria ( P < 0.01), and Verrucomicrobia ( P < 0.05) reads were significantly affected by diet, and Proteobacteria ( P < 0.01) and Verrucomicrobia ( P < 0.05) reads were significantly influenced by age. At the genus level, Escherichia/ Shigella ( P < 0.01) was overrepresented in diet A (high fiber) relative to diet D (high starch) in 52- and 62-day-old rabbits. Venn diagrams and heat map plot analyses revealed that the number of gut species shared between animals with different diet treatments increased with age. These results suggest that dietary fiber per starch ratios and age significantly alter the composition of caecal microbiota in growing rabbits. [ABSTRACT FROM AUTHOR]

This study investigated the preventive role of resveratrol in cisplatin-induced nephrotoxicity. The study used groups of New Zealand rabbits that were treated as follows: group C (cisplatin treated), group R (resveratrol treated), group R+C (resveratrol + cisplatin treatment), and group E (control group). Kidney levels of glutathione were significantly lower in group C than in groups E and R, whereas glutathione levels in group R+C were found to be similar to the control values. Malondialdehyde levels in group C were significantly higher than in groups E and R. However, malondialdehyde levels in group R+C were similar to group E. Kidney levels of nitric oxide were significantly higher in the cisplatin group than in the control, whereas nitric oxide levels were at basal values in group R+C. Cisplatin treatment significantly reduced kidney levels of glutathione peroxidase, superoxide dismutase, and catalase activity compared with those of group E, whereas resveratrol treatment significantly increased levels of glutathione peroxidase, superoxide dismutase, and catalase activity in group R+C. However, cisplatin injection did not affect mRNA levels of glutathione peroxidase, superoxide dismutase, or catalase enzymes. Histopathological and immunohistochemical analyses indicated that cisplatin caused kidney damage, which was mostly prevented by resveratrol treatment. In conclusion, resveratrol ameliorates cisplatin-induced oxidative injury in the kidney of rabbit. [ABSTRACT FROM AUTHOR]
