Use of Sesame Bran (Industry Byproduct) in the Broiler Chicks Diet and its effects on the performance and Carcass quality characteristics

The study was carried out to evaluate the effects of partially replacement of sorghum (Fetrita) with sesame bran in the broiler chicks’ diet, on the performance and carcass quality. The experiment was conducted at the experimental poultry farm (open sided house) of Faculty of Agricultural Technology and Fish Sciences, University of Alneelain, Jebel-Awlia, Khartoum South. A total of ninety, one-day-old unsexed broiler chicks (Hubbard) were assigned into nine pens in groups of ten chicks in a pen, in a completely randomized design. The experiment lasted 5 weeks (8 -42 day). Three experimental iso-caloric and iso-nitrogenous diets were supplied ad -libitum. 10% of sorghum was replaced with sesame bran + 0.1% of enzyme in the fIrst experimental diet. In the second diet 20% of sorghum was replaced with sesame bran + 0.1% of enzyme. The third one which is the control was free of sesame bran and enzyme. Each experimental diet was fed to three replicates. Feed consumption, weight gain, feed conversion ratio and carcass quality characteristics (Dressing, Heart, gizzard, liver and abdominal fat %) were recorded for the individual replicate of each dietary treatment. Partially replacement of sorghum with 10 or 20% sesame bran + 0.1% enzyme resulted in a significant (P 0.05) effect on weight gain comparing to the control diet, during starter, fmisher and whole periods. 10% replacement of sorghum with sesame bran produced significant (P< 0.01) lower fmal live body weight and (P< 0.05) dressing %, and 20% replacement of sorghum showed only significant (P< 0.01) lower fmal live body weight than control diet. It was concluded that replacement of 10 or 20% of sorghum with sesame bran in the broiler chick diet with supplementation of enzyme produces adverse effects on performance and dressing% only during fmisher period, but not during starter period during which it was recommended to reduce the cost of feed.
