An experiment was conducted to study the effect of TiO2 applied in 0g/m2, 30g/m2, 60g/m2 and 120g/m2 concentration, as a litter treatment agent on litter bacteriology, haematology, ammonia emission and ammonia lesions on broilers fed standard commercial diet and water ad lib on wood shavings based deep litter system at a depth of 6cm and 16birds/m2. Litter samples were collected weekly for ammonia while tissue samples were collected at the seventh week for histology and blood samples were also collected via cardiac venipuncture for haematology and blood chemistry. The result showed that RBC and WBC were significantly (P<0.05) elevated in 0g/m2TiO2 treatment (3.86x1012, 2.93x1012, 3.01x1012, 2.34x1012 and 27.16x109, 26.41x109, 21.47x109, 21.84x109) respectively. MCH and MCV were significantly (P<0.05) elevated (28.60pg, 34.26pg, 30.96pg, 44.71pg and 87.42fl, 103.41fl, 93.62fl, 134.52fl) in the 120g/m2TiO2litter treatments. There was a significant (P<0.05) elevation in serum sodium (132.27mEq/l, 135.07mEq/l, 135.33mEq/l, 138.67mEq/l); potassium (4.12mEq/l, 4.18mEq/l, 4.03mEq/l, 4.47mEq/l); globulin (1.23g/dl, 1.85g/dl, 1.35g/dl, 2.47g/dl) and conjugated bilirubin (5.11mg/dl, 5.52mg/dl, 5.55mg/dl, 6.07mg/dl) in 120g/m2TiO2 litter treatment. There was no significant difference (P>0.05) in ammonia even though 60g/m2TiO2 litter treatment retained more ammonia (29.77, 29.25, 33.16, 30.01). It was concluded that TiO2 is beneficial as a litter treatment agent especially at 60g/m2 rate.
