Abstract


Spreading zeolites on litter floor of broiler house at rate of 5.0 kg/m2 increased broiler carcass percentages up to 5.41 percents. Effect of zeolites-spread litters on broiler carcass and non-carcaSs components under different floor spaces had been performed in five weeks. As many as 324 chicks of a day-old Hubbard strain were fed with rations contained 3,000 -3,100 Kcal/I<g ME and 21 %crude protein during starter period and fed with the ration contained 20% crude protein duringfinisher period. The chicks were allocated to three different floor spaces (10, 12, and 14 heads/m2) and three different zeolites-spread litters (0.0, 2.5, and 5.0 kg zeolites/m2) under completely randomized design with factor 3 x 3 and 3 replications. Parameters concerned of present research including percentages of both carcasses and non-carcass components were analyzed with analysis of variance (ANOV A) and least .significant different.
Results of the preseqt research showed that there was no interaction effect between floor spaces and zeolites-spread litters on all parameters concerned. Floor spaces affected the percentages of gizzard, kidney, and spleen significantly (p<O.05) but neither carcass nor abdominal fat percentage was af.fectedby the floor space. The zeolites-spread litters only affected significantly (P<O.05) on carcass percentage. Spreading zeolites at rates of
5.0 kg/m2 on litter floor resulted in the highest carcass percentage (p<O.05) while rates of 25 kg/m2 resulted the same carcass pen:entage as the rates of 0.0 kg/m2. It was concluded that spreading zeolites at rates of 5.0 kg/m2 on litter floor under different floor spaces increased can:ass percentages up to 5.41 percents.
