Effect of Processing Method of Sesame (Sesamum indicum Linn.) Seeds on the Growth Performance and Nutrient Utilization of Broiler Chicks

摘要

Objective: This research was conducted to investigate the effect of feeding processed sesame seed (Sesamum indicum) on the performance and nutrient utilization of broiler chicks. Method: 400 day old (Anak, 2000) white strain unsexed broiler chicks were allocated to four treatments with each treatment having two replicates in a completely randomized design (CRD). Each treatment contained 100 chicks with 50 chicks per replicate. A control diet, which served as treatment 1 had full fat soya bean, whereas the cooked, pre-pressed and de-hulled seed based diets served as treatments 2, 3 and 4 respectively. Feed and water were supplied ad libitum. Result: The pre-pressed Sesame seeds had significantly (P<0.05) higher crude protein and NFE values but the ether extract was significantly (P 0.05) differences in the means of the other treatments. The mean values for mean weekly feed intake of the birds fed de-hulled and pre-pressed (291.21 g) and de-hulled (292.21 g) were significantly (P<0.05) higher than that of the control (335.96 g), which was significantly lower than cooked (260.92 g). The results for body weight gain and FCR follow the same trend. The digestibility of crude fibre in the pre-pressed seeds (40.80%) is significantly (P<0.05) higher, and least in the cooked (31.02%) and control treatment. A cooked Sesame seed give better feed conversion ratio than other processing methods but does not necessarily correspond to the best performance. Conclusion: Arising from this study, the three processing methods show promise as feed for broiler chicks. As a result, all three processing methods are commended for the different objectives for which they perform optimally but the pre-pressed proved to be the best method of processing sesame seeds for appreciable result on crude protein levels.
