Figure shows the weight evolution of animals over time. It is found that overall, until day 28, the weight difference is not significant between the control group and the experimental group. Beyond 28 days, faster growth was observed in animals treated BIOFOR. It was a very significant increase in weight gain in the batch treated BIOFOR at day 34  (P <0.01), 41 (P<0.0001), 48 (P<0.01) compared to the control group. On day 48 the chickens which had BIOFOR prophylaxis plan exceeded the average level of 2 kg (2096 ± 54.556), while the batch having had the conventional prophylaxis plan is below  2 Kg (1851 ± 60.682).
