Abstract | Feedstuffs and high temperature are the two major constraints for tropical poultry. The Separate Energetic Feeding (SEF) was suggested as an alternative to limit the harmful effects of the high temperature on the productivity of fowls under hot climate. To check this assumption, one hundred 8 -week- old chicks Guinea fowls were distributed in two groups. Each group was divided into two replicates of 25 birds each. The first group (control; n=50) received a conventional food containing 2953. 75 Kcal/kg metabolizable energy and 17. 31% crude protein. The second group (treatment group; n= 50) was separately fed with two fractions: (1) caloric feeding with 2141.75 Kcal/kg metabolizable energy and 4. 24% of crude protein and (2) crude proteins and mineral stuffs fraction containing 812 Kcal/kg metabolizable energy and 13.07% crude protein. Feed and water were offered ad libitum. The mean average live weight was significantly higher (P<0. 05) in guinea fowls fed with fractioned meals. Birds receiving a SEF reached the commercial body weight (BW) one week earlier than the control group (P<0. 05). The results show that the voluntary consumption of the energy fraction increased with age of birds in both groups but was moderately higher (P<0. 05) in the treated group. This study highlighted that SEF is an alternative to limit the harmful effect of heat stress in tropical climate and may be useful for poultry production in developing countries where formulated feeds and premixes are limited.
