Abstract 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.
Effect different fat sources on performance and carcass characteristics of broilers
(2017) Mohamed Elamin Ahmed; Talha Elsadig Abbas
Abstract An experiment was conducted to evaluate the effect of dietary fat source on broiler performance and carcass characteristics. Ninety one day-old unsexed Ross 308 broiler chicks were purchased from a commercial hatchery. Chicks used in this study had uniform initial live body weight (44.31g ±0.90). The chicks were randomly allotted to 9 pens (1mx1m) in groups of 10 chicks in a pen. The chicks were divided into three dietary treatments; each group was replicated three times. The birds were fed on starter and finisher experimental diets containing vegetable oil (A), hydrogenated vegetable oil (B) and beef tallow (C). At the end of the experiment (42 days), 2 birds per replicate were randomly selected for carcass characteristics and internal organs evaluation. The results revealed that different sources of fat had no significant (p≥0.05) effect on live performance parameters during different growth phases. However, body weight gain during starter phase (0-3 weeks), was significantly (p≤0.05) higher for birds fed dietary hydrogenated vegetable oil and beef tallow versus those fed vegetable oil. During the finisher phase (4-6 weeks), broilers fed hydrogenated vegetable oil grew faster by 13.9 and 12.0% versus those fed vegetable oil and beef tallow, respectively. In addition, FCR and PER of broilers fed dietary hydrogenated vegetable oil were improved by 12.3 and 12.4%, respectively as compared with those on dietary beef tallow.
