Responses were grouped into breeding, feeding, disease and organizational constraints. Overall, the main perceived breeding constraints were failure of farmers to bring animals for insemination at the right time of heat (71.25%), repeat breeding in crossbreds (68.75%) and high incidence of reproductive disorders (66.25%). Main perceived feeding constraints were the farmers' preference for local substitutes for good quality concentrates (42.50%) and ignorance about balanced feeding (41.25%). Main perceived constraints related to disease prevention were inadequate supply of medicines (61.25%), problems of local quacks (53.75%) and farmers' preference for quacks (46.25%). Main organizational constraints were inadequate recognition of good work by superiors (72.5%), inadequate communication facilities for extension contact (70%) and lack of participation in setting goals (63.75%). 收起
