Bioavailability Of Minerals In Different Vegetable Protein Sources Commonly Used In Broiler Ration - 2010

The study was designed to investigate the relative bioavailability of minerals in different vegetable protein sources commonly used in broiler ration. The study was conducted in the Poultry Experimental Shed, University of Veterinary and Animal Sciences, Lahore. For this purpose 200 day old broiler chicks were purchased and were randomly distributed into five equal treatment groups A, B, C, D & E containing soyabean based control diet, rapeseed meal, sunflower meal, canola meal and guar meal respectively. Each treatment had 4 replicates having 10 chicks each. Birds were placed on floor for first 10 days then were shifted to cages on day with in same treatment and replicate groups and were fed on experimental feed. Feed and water were provided ad libitum. Body weight and feed consumption were recorded weekly and FCR and weight gain was also calculated accordingly.
The experiment was terminated at day 21, all birds were weighed and feed consumption was recorded to calculate weight gain and FCR. Two birds per replicate were randomly selected and 5m1 blood was taken from wing vein prior to slaughtering. After slaughter, organ weights, left tibia bone were taken. Blood samples, left tibia bone ash, and excreta samples were collected for analysis of macro (Ca, P, K, Mg, and Na) and microminerals (Mn, Cu, and Fe) analysis.
Data when statistically analyzed showed that there was a significant differences (P<0.05) between body weights, Birds fed canola and guar meal showed the highest (P<0.05) body weight compared to control birds. Feed consumption & FCR values
showed a non significant difference (PAmount of available Ca in plasma was significantly higher (PO.05) difference among all treatment groups, whereas microminerals like Cu, Mn and Fe showed a significant difference (PThe overall bioavailability of macro minerals (Ca, P, Mg, K and Na) and microminerals (Cu and Fe) showed significant (P
