Résumé partiel
The objectives of this study were to evaluate the effect of dietary Inclusion of Faidherbia albida pods powder on growth performance traits and some blood metabolites in broilers chicks. The F. albida pods was collected from trees in, Elshigailab area Khartoum State during summer season .The study were conducted at the Department of Biochemistry, Faculty of Veterinary Medicine University of Khartoum. A total of 160 one – day - old unsexed chicks (Ross 308 strain) were used Chicks were kept in a semi-closed housing system. Newcastle and Infection bursal disease vaccines were administered in drinking water on days 11 and 15 of age, respectively. Birds were distributed randomly into 4 dietary treatment groups with 2 replicates (10 birds per replicate) in a complete randomized design and randomly allotted to four rations (A, B, C and D) approximately isocaloric and isonitrogenous. Ration A served as a control and was composed of basal diet without F. albida, while rations B, C and D contained F.albida at the levels of 10, 20 and 30%, respectively. The basal diet contained sorghum, groundnut meal and concentrate. Chickens were allowed to feed ad libitum, for an experimental period of 5 weeks. Feed intake (FI), body weight gain (BWG) and feed conversion ratio (FCR) were measured weekly. Blood samples were randomly collected from chickens of all groups at weeks 4 and 6, from 2 bird/replicate. Parameters assessed were serum levels of a total protein, albumin (alb), triacylglycerol (TAG), total cholesterol (TC), high density lipoprotein (HDL), low density lipoprotein and LDL. Statistical analyses system (SAS version .9) was used for data analysis using ANOVA test. Means were separated according to Duncan’s multiple range test ; Significant was accepted at P≤0.05.The proximate analysis of F.albida showed that the crude protein content was 12.25% and fat 1.13%. The results revealed a numerical increase in body weight in birds with inclusion of 10%, 20% and 30% F. albida compared to the control.
