A total of 192 one-day-old Ross 308 broilers (initial body weight: 31.30±0.41 g) were used in this experiment for 28 days. Treatments were as follows: basal rice husk (CON), rice husk + 1% illite (T1), rice husk + 1% zeolite (T2), and rice husk + 0.5% illite + 0.5% zeolite (T3). The percentage of illite and zeolite was calculated on a weight of litter. Each treatment had four replicates, with 12 birds per pen. Each pen was provided with 5 kg of rice husk as litter. Litter moisture content was significantly decreased (P<0.05) in the T1, T2, and T3 groups compared to CON group at week 4. In litter nitrogen, the T1 group showed significantly lower (P<0.05) litter nitrogen content than the other groups at weeks 1, 2, and 3. Also, the T3 group showed a significantly lower (P<0.05) litter nitrogen content than the CON and T2 groups at weeks 2 and 3. The counts of E. coli in the litter were significantly decreased (P<0.05) in the T1 group compared to the CON group at weeks 2 and 3. Moreover, the counts of Salmonella in the litter were significantly decreased (P<0.05) in the T1 group compared to the CON group at week 4. The FPD score significantly decreased (P<0.05) in the T1 group compared to the CON group. In conclusion, spraying illite could be an ideal way to improve litter quality and decrease FPD in broilers.
