Abstract
A feeding trial was conducted to study the performance of beef cattle when the feeding system was altered. Ten Australian Commercial Crossbred bulls which were being fattened on pineapple waste-poultry litter (PW-PL) based ration and of average body weight of 190.5 kg were randomly divided into two groups of five animals each. One group was offered ad lib expeller palm kernel cake (PKC-E), while the other group was continued on ad 1lib PW-PL based ration. The average daily fresh feed and dry matter intakes were significantly higher (P<0.05) for the group fed PW-PL. The animals whose diet was changed to PKC lost an average of 0.67 kg/day, while the other group maintained its body weight(-0.03 kg/day).The average weight loss for the group fed PKC was 21.4 kg while the group fed PW-PL ration lost about 1.0 kg. This indicated that growth performance was affected when the diet was suddenly changed presumably due to alteration of the rumen microbial ecosystem. Economic evaluation and animal performance in mini-feedlots and in a commercial feedlot were also assessed. Mini-feedlots based on PKC had lower annual gross returns than commercial feedlotting system based on PW-PL. Profitability of mini-feedlot cattle could have been increased if the fattening period had not exceeded 120 days.
