Abstract

This study was conducted to determine how broiler performance with the level of crude protein(23 CP%, 21 CP% and 19 CP%) can be changed and affected, adding Alum(Al$_{2}$(SO$_{4}$)$_{3}$ㆍ14H$_{2}$O) and no Alum in litter(two ALUM levels and 3 Protein levels with 2$\times$3 factorial design). Alum was added as a top dressing to the litter at a rate of 200g ALUM / kg of rice bran. With the exception of the protein levels for feed :gain(P〈 0.05), there were no significant differences in feed intake, weight gain and feed :gain of chicks. For ammonia gas emission, both the main effects of Alum and protein(P〈 0.01 and 0.05) at 3weeks and interaction between Alum and protein(P〈 0.05), the main effect of Alum(P〈 0.01) at 6weeks did affected them. In litter excluded the main effects of Alum(P〈 0.05), there was a significant difference among N contents ranged from pH to the rate of C: Organic-N(P〈 0.01).
