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 (P<O.05). Organ weight revealed non significant difference in liver & heart weights (P<O.05), however significantly (P<O.05) highest weights were observed for birds fed diet containing guar meal.
Amount of available Ca in plasma was significantly higher (P<O.05) when guar meal was fed as compared to P arid Mg which showed non significant (P<O.05) differences between treatments and the amount of available minerals Ca, P, Mg, K, and Fe in bone ash were also non significant (P<O.05) among birds fed control, rapeseed, sunflower, canola, and guar meal. The amount of available macrominerals (Ca, P, and Mg) in feed showed a significant difference (P<O.05) when birds were fed sunflower meal, control and guar meal. However, Na, and K levels of feed were non significant (P<O.05). The amount of available macrominerals (Ca, K and Na) in excreta significantly showed (P<O.05) difference when sunflower and guar meal were fed while P and Mg showed non significant (P>O.05) difference among all treatment groups, whereas microminerals like Cu, Mn and Fe showed a significant difference (P<O.05) when birds were fed a soya based control diet.
The overall bioavailability of macro minerals (Ca, P, Mg, K and Na) and microminerals (Cu and Fe) showed significant (P<O.05) among treatments groups. However Mn showed non significant (P<O.05) difference with highest bioavailability of guar meal. The results showed that among protein source supplements, soybean, sunflower, canola and guar meal showed higher digestibility and minerals content as compared to rapeseed meal.
