Abstrak
This research was carried out to study the effect of pollard in diet supplemented with yeast on broiler performance andammonia-Nconcentrationofexcreta. The birdsused in the experiment were 2 up to 6 weeks of age. Thetreatments were usingfour birds with six replications per replication in a completely Randomized Design (CRD).Thosediets treatmentwere evaluatedas follows: (A)diet without pollard as a control,(B) diet with 15 % pollard,(C) diet with 15% pollard and 0,20 % yeast supplemented, respectively. Diet and drinking water were provided ad libitum. The variablesobserved in this experiment consists of: feed consumptions, final body weight, live weight gains (LWG)s, feed conversion ratio(FCR), and ammonia-Nconcentration of excreta. The studyshowed that feed efficiency and ammonia-Nconcentration in excreta of birds dietary 15% pollardsignificantly (P<0.05)lower than those of control birds. Moreover,supplementation of 15 % pollard combined with yeast significantly increased (P<0.05) live weight gains and feed consumption, but significantly decreasing (P<0.05) ammonia-Nconcentration in excreta of broiler. It can be concluded that inclusion of 15% pollard in diet supplemented with yeast increased performance but decreased ammonia-Nconcentration in excreta of broiler. Key words :Pollard, Yeast, Performance, Ammonia-N and Broiler.
