Grasscutter farming is an alternative solution for the fight against poaching. However, diseases are often rampant on farms and very few studies are carried out in this direction. The aim of this study was to prevent the risk of contamination of grasscutter farmers by zoonosis in Côte d’Ivoire. A survey was therefore carried out on 39 farms in the south of the country to collect information on breeders, diseases encountered, their treatments and the pace of cleaning of the grasscutter farms. It appears that all the farmers interviewed were aged between 25 and 62 years old and The majority were male (97.43%). Of these, 74.35% had received training. Also, they carried out other activities. Indeed, 33.33% were farmers, 25.64% breeders, 20.51% civil servants and 20.51% men in small trades. Sixteen percent (16%) of grasscutter farmers cleaned their farms daily, 16% did so weekly and 68% monthly. The most common pathologies were sudden death (84.21%), cannibalism (73.68%), injuries (57.89%) and bristling hair (57.89%). The others (weight loss, diarrhoea, belly bloating and coughing) were observed by less than 50% of farmers. To eradicate them, 58% used medicinal plants, 21% alternated medicinal plants and veterinary products and 10.5% used only veterinary products. On the other hand, 10.5% of farmers did not use any product. This study has made it possible to identify pathologies rampant in the breeding of grasscutters in Côte d’Ivoire and means of control. Training sessions on hygiene rules in livestock farming should be considered.

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.
