Use of Cassia obtusifolia L. as Feed Resource for Ram Fattening in the Sahelian Region of Burkina Faso. The objective of this study was to analyse economic and technical performances of the use of straws from Cassia obtusifolia as substitute feed to soybean straws and cotton seed cake for ram fattening in the Sahelian region of Burkina Faso. Five feed rations were tested with different levels of Cassia obtusifolia in substitution to soybean straws (Vigna unguiculata) and cotton cake at rates varying between 0 to 20%. The control ration contained 40% of cotton cake and 20% of soybean straws. The results show that Cassia obtusifolia (CO) is an efficient feed resource. The average growth rate varied from 56.6 ± 22.3 g/day/animal in the control group to 105.2 ± 33.7 g/day/animal in the groups fed CO. Economically, rations with 25% and 50% cassia substituted to cotton cake showed low variable costs and high profit. These rations are likely to be accessible to any farmers regardless to their resources. On the other hand, the diet with 50% CO substituted to soybean straws maintained high profits, in spite of high production costs. This ration could only be accessible to farmers owning relatively important resources.
