“…These dairy farms may interact with supply chain collectors in three ways: (i) no interaction when the milk market is missing or functioning poorly (Staal et al, 1997;Moll et al, 2007;Nkya et al, 2007); (ii) through short-range networks such as artisanal dairies, direct consumer sales, or peddling, with or without product processing, supplying milk products to urban populations and people living near production sites (Corniaux et al, 2005;Dieye et al, 2005); (iii) through milk collection chains managed by agro-processing firms that supply large-scale dairies with milk collected from numerous small-scale farmers. In the latter case, cooperatives sometimes are established to play an intermediary collection role between the farmers and the dairy (Owango et al, 1998;Holloway et al, 2000;Sraïri et al, 2009a). The establishment of formal contracts between farmers and supply chain collectors stimulates the adoption of innovative livestock practices (Dieye et al, 2008) such as providing fodder and feed supplements to increase production and lessen seasonal fluctuations, breeding and improved hygiene.…”
