Rabbit

Rabbit
Habitat and range Outdoor entrance to a rabbit burrow Rabbit habitats include meadows, woods, forests, grasslands, deserts and wetlands.[1] Rabbits live in groups, and the best known species, the European rabbit, lives in underground burrows, or rabbit holes. A group of burrows is called a warren.[1] More than half the world's rabbit population resides in North America.[1] They are also native to southwestern Europe, Southeast Asia, Sumatra, some islands of Japan, and in parts of Africa and South America. They are not naturally found in most of Eurasia, where a number of species of hares are present. The European rabbit has been introduced to many places around the world.[2] Biology A skin-skeletal preparation showing its incisors Evolution Because the rabbit's epiglottis is engaged over the soft palate except when swallowing, the rabbit is an obligate nasal breather.

Fédération Française de Cuniculiculture Leporidae The term "leporid" may be used as a noun, meaning "a member of the family Leporidae" or as an adjective meaning "like members of the Leporidae". The common name "rabbit" usually applies to all genera in the family except Lepus, while members of Lepus (almost half the species) usually are called hares. Like most common names however, the distinction does not match current taxonomy completely; jackrabbits are members of Lepus, and members of the genera Pronolagus and Caprolagus sometimes are called hares. Various countries across all continents except Antarctica and Australia have indigenous species of Leporidae. Characteristics[edit] Leporids are small to moderately sized mammals, adapted for rapid movement. Leporids range in size from the pygmy rabbit (Brachylagus idahoensis), with a head and body length of 25–29 cm, and a weight of around 300 grams, to the European hare (Lepus europaeus), which is 50–76 cm in head-body length, and weighs from 2.5 to 5 kilograms.

CUNICULTURE MAGAZINE Volume 30 (année 2003), pages 3 - 7 Le point sur les travaux de recherche concernant l'entéropathie épizoo E/ Résultats de l'enquête épidémiologique conduite par l'AFSSA Une enquête épidémiologique analytique rétrospective a été réalisée entre décembre 2000 et mai 2002. Elle a porté sur 96 élevages en claustration conduits en bandes. Les élevages ont été classés en deux catégories vis à vis de l'EEL d'après le résultats obtenus au cours de 5 bandes consécutives précédant le passage de l'enquêteur. Dans les élevages " cas " les animaux issus des 5 dernières bandes ont présenté le tableau lésionnel typique de l'EEL et la mortalité moyenne en engraissement était supérieure à 12%. Compte tenu du mode de classification, 37 élevages ont été placés dans la catégorie " cas " et 28 dans la catégorie " témoin ". Les analyses mathématiques utilisées pour classer les variables expliquant le mieux les différences entre les élevages " cas " et les élevages " témoin " ont permis d'identifier 4 facteurs explicatifs principaux (tableau 2) .

Otter Etymology[edit] The word otter derives from the Old English word otor or oter. This, and cognate words in other Indo-European languages, ultimately stem from the Proto-Indo-European language root *wódr̥, which also gave rise to the English word "water".[1][2] Terminology[edit] An otter's den is called a holt or couch. Male otters are called dogs, females are called bitches, and their offspring are called pups.[3] The collective nouns for otters are bevy, family, lodge, romp (being descriptive of their often playful nature) or, when in water, raft. The feces of otters are typically identified by their distinct aroma, the smell of which has been described as ranging from freshly mown hay to putrefied fish;[4] these are known as spraint.[5] Life cycle[edit] The gestation period in otters is about 60 to 86 days. Characteristics[edit] Otters have long, slim bodies and relatively short limbs with webbed paws. For most otters, fish is the staple of their diet. Species[edit] Genus Lutra Genus Hydrictis

CUNICULTURE MAGAZINE Volume 31 (année 2004) page 48 Le Cycostat 66G autorisé jusqu'en 2014 pour les lapins en engraissement La robénidine ou plus exactement le Chlorhydrate de Robénidine, commercialisé par la firme Alpharma sous le nom de Cycostat 66G (antérieurement connu sous le nom de Robenz) est un additif alimentaire utilisé pour prévenir le développement intempestif de différentes formes de coccidiose chez le lapin, le poulet et la dinde. Chez le lapin il peut être employé à la dose de 50 à 66 mg de produit actif par kg d'aliment fini. Il s'agit d'un anticoccidien à utiliser de manière préventive et non pour tenter de guérir des lapins qui seraient déjà atteint d'une coccidiose intestinale manifeste. Dans le Cycostat 66 G, la robénidine est dosée à 66 g/kg, ce qui permet d'utiliser le produit commercial à raison de 1 kg/tonne d'aliment.

Mustelidae Variety[edit] Mustelids vary greatly in size and behaviour. The least weasel is not much larger than a mouse, while the giant otter can measure up to 2.4 m (7.9 ft)[citation needed] in length and sea otters can exceed 45 kg (99 lb) in weight. The wolverine can crush bones as thick as the femur of a moose to get at the marrow, and has been seen attempting to drive bears away from their kills. As well as being one of the most species-rich families in the order Carnivora, the family Mustelidae is one of the oldest. Characteristics[edit] Within a large range of variation, the mustelids exhibit some common characteristics. With the exception of the sea otter,[2] they have anal scent glands that produce a strong-smelling secretion the animals use for sexual signaling and for marking territory. Most mustelid reproduction involves embryonic diapause. Mustelids are predominantly carnivorous, although some will sometimes eat vegetable matter. Ecology[edit] Human uses[edit] Systematics[edit]

Etude de la protection virologique induite par la vaccination contre la myxomatose chez le lapin européen. Thèse d'exercice, Ecole Nationale Vétérinaire de Toulouse - ENVT, 2008, 118 p. La myxomatose, maladie majeure du lapin européen (Oryctolagus cuniculus), sévit de façon enzootique sur plusieurs continents. C’est une maladie infectieuse, virulente, inoculable, dont l’agent pathogène est un virus de la famille des Poxviridae, genre Leporipoxvirus. Celui-ci provoque, pour sa forme classique, une pathologie souvent létale, caractérisée par une immunodépression sévère et l’apparition de pseudotumeurs cutanées : les myxomes.

Mudskipper Adaptations Compared with fully aquatic gobies, these fish present a range of peculiar behavioural and physiological adaptations to an amphibious lifestyle. These include: Anatomical and behavioural adaptations that allow them to move effectively on land as well as in the water.[3] As their name implies, these fish use their fins to move around in a series of skips. Even when their burrow is submerged, mudskippers maintain an air pocket inside it, which allows them to breathe in conditions of very low oxygen concentration.[11][12][13] Species Periophthalmus cantonensis venturing on land Periophthalmodon septemradiatus territorial defense call and jumping ability The genus Periophthalmus is by far the most diverse and widespread genus of mudskipper.

Odobenidae Odobenidae is a family of Pinnipeds. The only living species is walrus. In the past, however, the group was much more diverse, and includes more than ten fossil genera. Taxonomy[edit] All genera, except Odobenus, are extinct. Evolution[edit] Sources[edit] Encyclopedia of Marine Mammals, ed. OFFICE VETERINAIRE FEDERAL - Aide-mémoire concernant l’abattage des lapins. En Suisse, la viande de lapin est un produit de niche. La production actuelle doit garantir des conditions d'abattage respectueuses de l'espèce et un niveau d'hygiène irréprochable. Par ailleurs, le stress que peuvent ressentir les animaux avant d'être abattus influe négativement sur la qualité de la viande. Il est donc important que les lapins d'engraissement en fin de vie soient traités conformément aux besoins de l'espèce. La fourrure du lapin est également appréciée pour confectionner cols, manchons et chaussures. Les lapins doivent être étourdis avant d'être abattus.

Penguin Although all penguin species are native to the Southern Hemisphere, they are not found only in cold climates, such as Antarctica. In fact, only a few species of penguin live so far south. Several species are found in the temperate zone, and one species, the Galápagos Penguin, lives near the equator. Etymology The word "Penguin" first appears in the 16th century as a synonym for Great Auk.[1] When European explorers discovered what are today known as penguins in the Southern Hemisphere, they noticed their similar appearance to the Great Auk of the Northern Hemisphere, and named them after this bird, although they are not closely related.[2] The etymology of the word "penguin" is still debated. An alternative etymology links the word to Latin pinguis, which means "fat". Systematics and evolution Living species and recent extinctions Adélie Penguin (Pygoscelis adeliae) feeding young. The number of extant penguin species is debated. Subfamily Spheniscinae – Modern penguins Fossil genera Taxonomy

Hummingbird Hummingbirds are New World birds that constitute the family Trochilidae. They are among the smallest of birds, most species measuring in the 7.5–13 cm (3–5 in) range. Indeed, the smallest extant bird species is a hummingbird, the 5-cm Bee Hummingbird. They are known as hummingbirds because of the humming sound created by their beating wings which flap at high frequencies audible to humans. They hover in mid-air at rapid wing flapping rates, typically around 50 times per second,[1] but possibly as high as 200 times per second, allowing them also to fly at speeds exceeding 15 m/s (54 km/h; 34 mph),[2] backwards or upside down.[3][4] Hummingbirds have the highest metabolism of any homeothermic animal.[5] To conserve energy when food is scarce, they have the ability to go into a hibernation-like state (torpor) where their metabolic rate is slowed to 1/15th of its normal rate.[6] The smallest species of hummingbird weighs less than a penny. Diet and specialization for food gathering[edit]

Auk An auk is a bird of the family Alcidae in the order Charadriiformes. Extant auks range in size from the least auklet, at 85 g (3 oz) and 15 cm (6 in), to the thick-billed murre, at 1 kg (2.2 lb) and 45 cm (18 in). They are good swimmers and divers, but their walking appears clumsy. Modern auks can fly (except for the recently extinct great auk). Due to their short wings, auks have to flap their wings very quickly in order to fly. Auks are superficially similar to penguins having black-and-white colours, upright posture and some of their habits. Auks live on the open sea and only go ashore for breeding, although some species, like the common guillemot, spend a great part of the year defending their nesting spot from others. Several species have different names in Europe and North America. Feeding and ecology[edit] The feeding behaviour of auks is often compared to that of penguins; both groups are wing-propelled pursuit divers. Evolution and distribution[edit] Systematics[edit]
