Radia Bernaoui, H. Peter Ohly, Kebbab Salim, Mohamed Hassoun The Mobile phone between challenge and expectations: a potential for information sharing between Algerian breeders and veterinarians Abstract Today, in addition to being informed about their sector, livestock actors want to be constantly connected to the outside world. In Algeria, among the various ICT supports, the mobile phone is currently the most accessible tool. Does this revolutionary tool contribute to the reduction of animal losses in the livestock sector and can it be considered as a tool for economic development? The aim of this paper is to try to determine how the two actors (livestock breeders and veterinarians) use the mobile phone, and then consider whether it may be regarded as an indispensable tool for the health protection of livestock and, accordingly, to what extent it can contribute to economic development. 1. Introduction We are interested in the relationship between two key actors – livestock breeders and veterinarians – and their impact on livestock protection and market development of animal breeding. A livestock animal cannot be productive without ongoing technical and sanitary care, which essentially involves the farmer. Then there is the veterinarian, who is responsible for following this production by providing care and wellbeing to the animal. Finally, there are the authorities in charge of preserving animal health and acting as confederates of the two actors. Today, in addition to being informed about their sector, livestock actors want to be constantly connected to the outside world. In Algeria, among the various ICT supports, the mobile phone (a smartphone with Internet applications and not just a mobile phone) is currently the most accessible tool. It fits well within the socio-cultural traditions of the country in terms of communication since it is based on speech. Furthermore, it brings together writing, sound and image, thus allowing connection between different social and age groups in a knowledge sharing framework. Moch (2012) notes that "communication is an art, that of formatting and conveying information”, while Moussoki (2005) states that "information is communication of knowledge; it is also communicated knowledge". Thus, the newly emerged professions based on market competition, must be reorganized by integrating the new function of knowledge management. Knowledge management capitalizes and transmits knowledge within institutions including the use of collaborative tools to share and disseminate knowledge. From this perspective, Abdelkader Djeflat, professor of economics, noted that Algeria must be integrated into this new era of globalization (2008). It is in this light
