Due to positive externalities and the need to work on a large scale, animal breeding is usually carried out by breeders associations or states. In Algeria, racehorse breeding is in the hands of unorganized breeders-owners. Through a survey conducted with 461 owners-breeders between 2009 and 2011, this study investigates their perceptions, objectives and practices regarding selective breeding. Racehorse breeding is a full-time professional activity for a third of interviewees. The holdings are small-sized with 77% owning one or two mares. The regular practice of insemination could categorize breeders according to their professionalization (38.4% professional vs. 61.6% occasional breeders). Seniority in the sector was also used to classify breeders, considering as “young” the breeders under 10 years experience (38.8%) and as “senior” those above 10 years (61.2%). More than professionalization, seniority shows a significant impact on practices and objectives. Thus, seniority influences breed choice (young breeders tend to specialize while senior own both Arabian and Thoroughbreds; p<0.001), age at first foaling (sooner among senior breeders; p<0.01), information sources considered for selecting stallions (senior use more diversified sources; p<0.01), the importance granted to the price of insemination (greater for the young breeders; p<0.001), the importance granted to the ranking compared to earnings (the ranking being more important to young breeders, p<0.001), and the priority given to breeding (young breeders give rather priority to a buy-race-resell activity; p<0.001). Finally, racehorse breeding in Algeria is poorly professionalized, the only financial goal being cost coverage. Despite inappropriate practices, an interest for selection is noticed. [less ▲]

Strategies to identify genetic polymorphisms responsible for inherited disorders in purebred dog population are often based on experimental studies whereas hospitals case reports provide widely and easily affordable information of clinical significance. When this clinical information is enriched with knowledge on the phylogenetic origins, breed histories of the dog and adjusted for known biases, they may lead the way to more in depth genetic research. We illustrated here with a very complex disease, the brachycephalic airway obstruction syndrome (BAOS). No cases were reported in the boxer breed while almost half of the dogs from the other brachycephalic breeds of the same phylogenetic cluster were BAOS, making these breeds good candidates for further genetic studies. Critical issues to improve utility of clinical data for genetic studies are discussed along with methods to handle biases inherent to such type of studies. [less ▲]

Il y a environ 20 à 60 millions d’années, l’autruche se retrouvait autour de la Méditerranée à l’Ouest, en Chine à l’Est et en Mongolie au nord. Une polémique anime les milieux scientifiques, surtout les paléontologues : les autruches ont-elles migrés d’Afrique vers l’Eurasie ou l’inverse ? Cependant, se référant aux autres espèces, il est unanimement admis qu’ il y a 1 million d’année seulement que plusieurs grands mammifères terrestres ont migré vers le sud en Afrique, les autruches aussi(voir Carte 1). En chine, on a retrouvé dans des caves occupées il y a 2500 ans avant l’ère actuelle, des coquilles d’œufs d’autruche (Anita Holtzhausen & Marlene Kotzé, 1990) La domestication de l’autruche remonte à la plus haute antiquité, et c’est tout naturellement dans le nord de l’Afrique que se rencontrent les témoignages des plus anciennes relations entre l’homme et l’autruche (Njikam N.I., 1997 ; Bruno Cornette et Lebailly, 1998). L’autruche, bien connu des Egyptiens, figure parmi les pictogrammes de l’écriture hiéroglyphique. [less ▲]

The gorilla sanctuary of Lossi experiments the synergy between scientific research and nature conservation. Three partners are involved in a management participative process. These partners include the Republic of Congo, the local community of Lossi and the European programme on the forest ecosystems in Central Africa. An investigation was carried out on the sanctuary of Lossi in 2003, in order to study in situ the effects generated by the participative management and to identify the constraints linked to the participative approach. The work of primatologists allowed the habituation of the gorillas to the human presence and opened eyesight tourism of western lowland gorillas. A camp for tourists and the access road to the sanctuary have been constructed. The tourism generated jobs in favour of the local population which is also a take-partner of contracts on road repairing. The income from the tourism allowed the construction of a health centre. However, the works of researchers and tourism activities failed during the outbreaks of the Ebola hemorrhagic fever and during the three civil war episodes. The consolidation and the long term of this process of co-management of natural resources of Lossi remains the establishment of a management that should include conservation, rural development and scientific research, with equitably in the distribution of gain between the partnerses.

This work compares two dramatically different types of wildlife management in Senegal, a country threatened by poaching and deforestation : the first concerns the management of the Niokolo Koba National Park, by a public utility service and the second, the management of the Bandia Reserve, a fenced area which surface is more than thousand times lower, by private investors. In order to do this comparison, the structure, type of management, evolution of flora and fauna, and management problems encountered for each protected area are analysed. This comparison allows to formulate some recommendations for a sustainable management of Senegalese wildlife. [less ▲]

Several species of wild animals are endangered with extinction in Cameroon. The ostrich, Struthio camelus, which is one of these animals, has been protected since 1994. In 2000, there were about fifty individuals left in the Waza National Park, in the far northern part of the country. The number of ostriches has steadily decreased in the park despite more than half a century of protection. This repressive management method has progressively evolved into a participative management method. The primary cause of this drop in number is poaching, which is carried out by the local populations searching for eggs whose shells are sold to tourists, and for adult animals killed for their meat, and even more so for their bone marrow which is widely used in traditional medicine. Commercial hunting is carried out by foreigners, the skin being used in the fabrication of hand-crafted objects. In addition to these problems, natural predation occurs, mostly by jackals, Canis aureus, and hyenas, Hyaena hyaena, which targets the hatchlings often already weakened by the harsh climactic conditions. One of the alternatives for the conservation of this species is the introduction of its breeding in “game ranching” or “game farming” near the park and urban centers where there are consumers of the products taken from this animal. The products of such breeding farms or ranches could be used as animals for reintroductions into the wild, improving the visual tourism, and be valorized on the national meat- and craft markets.

The aim of this study was to do surveys about bush meat networks around urban centers near the Monte Alen National Park in Equatorial Guinea. During 8 weeks, in the Mundoasi market, one of two principal market of Bata, 4328 wild animal carcases have been indexed, representating 22,600 kg of biomass. A total of 48 animals species have been identified, including 14 which hunting are prohibited. The mammals represent 91.87% of total number with 3 dominants orders, ungulates (37.7%), primates (28.6%) and rodents (18%). The duiker (Cephalophus), the African Brushtailed Porcupine and Guenon are the most important. The district of Niefang, Bata and Evinayong are the principal sources of supply. Hunting with gun becomes very important, follow by snaring, a very wasteful method. Despite that this business squarely growth, signs of wildlife decrease are perceptible, showing evidence of overexploitation. As far as Monte Alen National Park is concerned, this study shows the positive effects of this protected area as wildlife reservoir for peripheral hunting zones. [less ▲]
