dc.description.abstract This study was conducted to assess the effects of phase feeding on growth performance of broiler chicks. The experimental work consisted of a 7-week feeding trial, in which three different feeding programmes were fed to day-old broiler chicks (Hubbard). The chicks were reared on deep litter in an open experimental poultry house. The experiment was arranged in a completely randomized block design consisting of three rows (blocks) with three pens (experimental units) each, with 10 chicks per pen. Three experimental diets were formulated to contain different levels of ME and Crude protein; namely a broiler starter diet containing approximately 3072 Kcal ME/kg and 23.9% crude protein, a grower diet containing 3118 Kcal ME/Kg and 21.8% crude protein, and a finisher diet containing 3200 Kcal ME/kg and 18% crude protein. The three feeding programmes were randomized within each block giving three replicates per treatment. The first programme (treatment I) consisted of feeding the starter diet throughout the whole experimental period (7 week), While the second feeding programme (treatment II) consisted of feeding the starter diet for the first two weeks followed by feeding the grower diet for the following two weeks, followed by the finisher diet for the remaining two weeks of the experiment. In the third feeding viii programme (treatment III), the starter diet was fed for three weeks followed by the finisher diet for four weeks. Records were kept for weekly feed consumption, weekly live weight and live weight gain, feed conversion ratio, daily mortality and dressing percentage at the end of the experiment. The collected data was subjected to analysis of variance to assess statistical differences among the experimental treatments. The results diets not reveal any significant differences in productive parameters, but indicated marked trends in differences among the experimental treatment. These differences showed that the highest feed consumption and live weight gain were attained by the group of birds fed the starter diet throughout the experimental period. Feeding the starter diet followed by the finisher diet for four weeks resulted in the lowest total feed consumption, reasonably high body weight gain, lowest feed conversion ratio and highest dressing percentage. It can, however, be considered under the conditions of the present experiment that the three experimental feeding programmes supported similar productive performance of broiler, indicating a slight economic advantage of feeding the starter diet followed by the finisher diet en_US
