Abstract:
In this study we evaluated the effects of Savory powder on the performance, blood biochemical and intestinal characteristics of female Cobb 500 broiler chicks. Total of 240 one day broiler chicks were randomly divided into 4 treatments. Treatments were further divided into 6 replicates. Broilers were fed a basal diet as control group, basal diet with 0.2% Savory powder (S1), basal diet with 0.4% Savory powder (S2) and basal diet with 0.6% Savory powder (S3). The experiment was carried out for 6 weeks. Feed intake (FI) and body weight gain (BWG) was calculated for estimation of feed conversion ratio (FCR). At the end of the experimental period four birds from each replicate were randomly slaughtered to determine carcass characteristics and other parameters. The blood serum samples were subjected to biochemical analysis. For determination of intestinal characteristics and small intestine tissues samples were collected. All data were analyzed as a completely randomized design using General Linear Models (GLM). The significance of the differences among least square means of main effects was tested by Duncan's new multiple-range test. Data from this study showed BWG and FCR in broilers improved underfed different levels of Savory powder (P≤0.05). There were significant differences between carcasses traits under effect of feed Savory powder levels (p≤0.05). The results of this study showed that serum triglyceride, cholesterol LDL content decreased in groups fed by savory powder and HDL increased significantly (p≤0.05) instead. In addition, villus height decreased in S1 and S2 groups. An increasing crypt depth was seen on S2. According to these data villus widths, epithelium layer and goblet cells increased by using Savory, especially by using S2 (p≤0.05). In conclusion we could demonstrate that the savory powder may be used as ingredient in broilers ration without harming effects on carcass characteristics, blood biochemical parameters, and intestinal morphology of Cobb 500 broiler chicks.
