Feeding and spatial behaviours of transhumant cattle in southern Benin: implications for the sustainable management of rangelands

Feed intake on pastures plays a vital role in cattle rearing in West Africa. However, the scarcity of pastures during the dry season may result in changing grazing behaviour by cattle. Therefore, we studied the management practices of transhumant herders on communal rangelands through monitoring of cattle herds’ behaviour in southern Benin. We expected changes in grazing behaviours of cattle and shifts in diet composition and diet overlaps between herds. Therefore, feeding and spatial behaviours of cattle were studied on six transhumant herds monitored daily, each during three consecutive days on communal rangelands of Djidja. In each herd, three adult cows of four to five years old were equipped with two GPS data loggers (GT-730FL-S) to monitor animals’ movements. The data loggers were set to record the positions of the animals every 10 s and direct observations of the animal activities were made. The results indicated that the activities of cattle varied greatly according to site (p < 0.05). Moreover, feed ingested varied with site. The ration was dominated by woody species with 70% Fabaceae, whereas shrubs and grasses were less represented, indicating a shift in diet. This analysis is required for better monitoring of grazing cattle.
