Abstract: The Integrated Farming System (lFS) is a production system that combines two or more, normally separate farming systems together, thereby facilitating synergism between the different subsystems in a farming system complex. Using a duck-fish-crop IFS, this study investigated selected perfonnance and reproductive traits of muscovy ducks during a production cycle and the growth potentials of Nile tilapia (Tilapia niloticus), including pond water dynamics (chemical and physical composition). The intemive or noointegrated (NIFS) farming system of duck and fish production served as the control. The feed given were: 12% crude protein for the ducks in the IFS, and 12% and 15% crude protein for ducks in the NIFS. The fish in the NIFS were fed ad libitum, while the fish in the IFS were given 50% less ad libitum feed. The results from the current study indicated that the ducks in the IFS conswned on the average 24% less feed compared to the ducks in the NIFS, and the trend for feed intake were: the 12%-CP IFS group < 15o/~CP NIFS group < 12O/o-CP NIFS group (P 15o/~CP NIFS group> 12%-CP NIFS group (P<0.05). Howev,,", production systems (IFS and NIFS) and dietary protein levels (12% and 15%), had no significant effects on egg sizes, live-weight of the duckling; at hatch. feed intake and post-hatch growth to 2 weeks of age (P>O.05). The fish in the IFS pond were significantly heavier and longer than the NIFS group, even though the IFS group were given 50% less feed than the NIFS group (P<0.05). At 20 weeks of age, fish yield were, 0.21 kglm' and 0.18 kglm' in the IFS and NIFS ponds respectively (P<0.05).
