Item Broiler performance and carcass characteristics as affected by graded levels of cinnamon (Cinnamomum zeylanicum) powder(2016) Mohamed Elamin Ahmed; Tamadur Ali Eltayb Algam; Talha Elsadig AbbasAbstract The present experiment was conducted to investigate the effect of different levels of cinnamon powder (0.0, 0.25, 0.50 and 0.75%) on broiler performance and carcass characteristics. One hundred and sixty, 1 day-old, unsexed broiler (Ross 308) weighed (48.1 g ±1.7) were randomly assigned to 16 floor pens (1m2 each) with wood shavings. The four isocaloric and isonitrogenous starter and finisher diets were formulated according to nutrient specifications of national research council (NRC.1994). Feed intake, live body weight, body weight gain, FCR and PER were determined for each pen. At the end of the experiment (6 weeks of age) two birds from each pen were randomly selected, weighed and manually slaughtered for carcass characteristics and internal organ determination. Data were analyzed in completely randomized design using the general linear model (GLM) procedure. Growth performance parameters except body weight gain, FCR and PER during starter phase were not significantly (P≥0.05) influenced by the dietary treatment. Body weight gain was significantly (P≤0.05) reduced for birds fed 0.50% cinnamon powder versus those fed control and 0.25%. FCR and PER for birds fed 0.50% and 0.75% cinnamon powder were significantly (P≤0.05) poorer than control. Most of the carcass traits and internal organs weights were not significantly (P≥0.05) affected by the dietary treatments. It can be concluded that inclusion of cinnamon powder up to 0.75% had no growth promoting effect on broiler chickens.Item RESPONSE OF BROILER CHICKS TO DIETARY MORINGA SEEDS AND ZIGBIR AS NATURAL GROWTH PROMOTERS(2014) MOHAMED ELAMIN AHMED; Talha ELsadig AbbasAbstract- In a 42-day experiment the effect of moringa seeds and Zigbir on growth performance and carcass characteristics was studied. One hundred twenty, 1day-old, unsexed Ross 308 broilers were purchased from commercial hatchery. The initial live body weight of the chick was (47.00 g ±0.67). The chicks were randomly assigned to 4 dietary treatments containing 3 replicates of 10 birds each. Starter and finisher experimental diets consisted of control, 0.04% zigbir, 0.5% undecorticated moringa seeds UDCM and 0.5% decorticated moringa seeds DCM. Data were analyzed in completely randomized design using the general linear model (GLM) procedure. Feed intake, body weight gain, FCR and PER were not significantly (P≥0.05) influenced by dietary treatments except feed intake during starter phase. Dietary moringa seeds both decorticated or undecorticated significantly (P≤0.05) reduced feed intake during starter phase compared to control and zigbir supplemented groups. However, DCM seeds improved overall body weight gain by 5.58, 5.78 and 10.43%, when compared to control, Zigbir and UDCM seeds group, respectively. During all growth phases, the performance of birds fed dietary zigbir was not significantly (P≥0.05) different versus control. On the other hand relative weight of breast was significantly (P≤0.05) higher for birds fed DCM seeds compared to the others. It was concluded that supplementation of DCM seeds improved growth performance of the broilers.
