\textbf{Abstract}
\begin{abstract}
\normalsize{
In spite of its higher prices and scarcity, sorghum grains is used as the main source of energy in poultry rations, while there are several alternative energy sources such as cane molasses which is considered as a cheep source of energy. The unsexed one"=day old broiler chicks are commercially used in Sudan, the data concerning the performance of male broiler chicks comparing with unsexed one are lacking and need to be investigated. The objectives of the study were to evaluate the effect of dietary inclusion of cane molasses on broiler performance and to compare the performance of male broiler chickens with the unsexed one. A (2 $\times$ 3) factorial arrangement was used in a completely randomised design to study the effect of two sexing patterns (male and unsexed chicks) and three levels of molasses (0, 10 and \mbox{24\,\%}) on broiler performance. A total of 6 treatments were employed and each treatment was replicated three times with six birds each. Feed consumption, weight gain, and FCR were recorded for each treatment. At the end of the experiment 3 birds were slaughtered to determine the weights of carcass and some internal organs. Blood samples were collected during the slaughtering for determination of cholesterol, triglycerides, protein and potassium. Muscle samples were taken for proximate analysis (protein, fat, Ash and moisture) and the PH of the muscle was determined. The results revealed that, feed consumption, body weight gain and feed conversion ratio (FCR) increased as the level of molasses increased. The greater feed consumed and the highest weight gain were observed with birds consumed diets incorporated with \mbox{24\,\%} of molasses. Males were better in weight gain and feed consumption than unsexed bird, while no differences in FCR. The greater blood protein and potassium levels were recorded with birds fed with \mbox{24\,\%} molasses treatment. Sexing had no significant effect on blood constituents. The weights of carcass, thigh, drumstick and breast were not affected by experimental treatments. The current study concluded that, the sugar cane molasses could be used up to \mbox{24\,\%} and male broilers were advisable to be adopted for broiler production than unsexed one. }
