This study, carried out in a rural area, at the grasscutter farm of Aheremou II (Taabo, Côte d'Ivoire) aims to determine the breeding performance of grasscutters and to test the effect of three grasses (Pennisetum purpureum, Rottboellia exaltata et Andropogon gayanus) on the growth of young female grasscutters. Each grass was tested on a group of 10 young female grasscutters. The temporary mating polygamous method was adopted. The results show that the breeding performance of this grasscutter farm was satisfactory: fertility (87.50 %), fecundity (315 %), prolificity (4.5). However, the reproduction rate (70 %) of the adult female grasscutters must be improved and the mortality rate (30.15 %) of the young grasscutters is very high. Forages of Pennisetum purpureum (12.14 g/d) and Rottboellia exaltata (11.55 g/d) give higher average daily gains (ADG) than Andropogon gayanus (8.83 g/d). Statistical analysis showed no significant difference (p > 0.05) between ADGs of the young female grasscutters fed with Pennisetum purpureum and those fed with Rottboellia exaltata. On the other hand, the statistical tests reveal that the ADGs of the young female grasscutters fed with Pennisetum purpureum and Rottboellia exaltata are significantly higher (p < 0.001) than the ADGs of those fed with Andropogon gayanus.

Abstract: (french)
Cette étude menée en milieu rural, dans la ferme aulacodicole d’Ahérémou II (Taabo, Côte d’Ivoire) a pour objectif de déterminer les performances de reproduction des aulacodes et de tester l’effet de trois graminées (Pennisetum purpureum, Rottboellia exaltata et Andropogon gayanus) sur la croissance des aulacodinettes. Chaque type de graminée a été testé sur un lot de 10 aulacodinettes. Le mode d’accouplement polygame temporaire a été adopté. Les performances de reproduction des aulacodes de cette ferme sont les suivantes : fertilité (87,50 %), fécondité (315 %), prolificité (4,5). Le taux de reproduction des aulacodines est de 70 %. Le taux de mortalité des aulacodeaux est très élevé, soit 30,15 %. Les fourrages de Pennisetum purpureum (12,14 g/j) et de Rottboellia exaltata (11,55 g/j) donnent des gains moyens quotidiens (GMQ) plus élevés que Andropogon gayanus (8,83 g/j). Les analyses statistiques ont montré que les GMQs des aulacodinettes nourries avec les fourrages de Pennisetum purpureum et de Rottboellia exaltata ne varient pas significativement (p > 0,05). Par contre, les tests statistiques révèlent que les GMQs des aulacodinettes nourries avec les fourrages de Pennisetum purpureum et de Rottboellia exaltata sont significativement (p < 0,001) plus élevés que le GMQ des aulacodinettes nourries avec le fourrage de Andropogon gayanus.
