assessment of age at first parturition by accounting censored data: the example of small ruminants in agropastoral herds in senegal.age at first parturition (afp) is an important reproductive trait when evaluating the herd productivity in tropical small-holder farming systems, particularly for small ruminants with high demographic turnover and commercial utilization. the article reports the afp probability distributions calculated on goats and sheep herds monitored for more than 10 years in three low-input livestock farming systems located from northern to southern senegal (louga, kaymor, and kolda) and representing differen ...201020217229
observations on natural and experimental interactions between schistosoma bovis and s. curassoni from west africa.surveys of 332 naturally infected bovines at eight abattoirs in senegal, the gambia and mali were carried out to determine the prevalence of infection with schistosoma bovis and s. curassoni and to pinpoint areas where the distribution of the species overlap. s. bovis was the commonest schistosome of cattle in senegal and mali being found in animals at seven abattoirs, the highest prevalence of 85.1% occurred at mopti in mali. s. bovis was the only bovine schistosome observed in the gambia. s. c ...19901969699
use of akaike information criteria for model selection and inference. an application to assess prevention of gastrointestinal parasitism and respiratory mortality of guinean goats in kolda, senegal.a field experiment was carried out in kolda (southern senegal) from july 1986 to july 1988. its goals were to: (1) describe the patterns of mortality of female guinean goats by age, season and year; (2) assess preventive measures against respiratory diseases and gastrointestinal parasitism in reducing mortality; and (3) estimate the overall impact of these measures on survival to 1 year of age. preventive measures for respiratory disease included vaccination against peste des petits ruminants (p ...200212392874
