Abstract
Feeding a high fat diet in the starter period of broiler is limited due to the immature development of
intestinal digestion of chicks. This experiment was conducted to examine the effect of graded levels of porcine
bile powder supplementation in high fat diet on growth performance and pancreatic lipase activity in starter
broilers. Total of 1,110 male, Arbor Acres broiler chicks were allocated into 6 treatments: Treatment 1: basal corn-
soybean meal diet containing 3% crude fat (control); Treatment 2: 6% crude fat diet (with crude palm oil
supplementation); Treatment 3: diet as in treatment 2 plus lecithin 0.50 %; Treatments 4, 5 and 6: diet as in
treatment 2 supplemented with porcine bile powder at 0.125, 0.25 and 0.50 %, respectively. Parameter on growth
performance were recorded and calculated. Pancreatic samples were collected and determined for pancreatic lipase
activity at days 4, 7, 14 and 21 of the experiment. The results demonstrated that on day 4, lipase activity of chicks
receiving lecithin and low levels of bile powder was higher than chicks fed on high fat diet (p < 0.05). Similar
result was shown in day 7 of the trial. It is obvious that low levels of bile powder supplementation increased lipase
significantly (p < 0.05) at day 14 of the experiment. At day 21, lipase activity of treatments 1 and 4 were higher
than other groups (p<0.05). In conclusion, porcine bile powder supplementation in high fat diet at 0.125 and
0.25% increased pancreatic lipase activity in starter broilers.
