Fifty water samples from different broiler farms in and around Lahore were collected from drinkers in sterile containers. Bacterial load was assessed using total viable count and coliform count. The counts were above the threshold level (50cfu/ml for coliform and 100cfu/ml for total viable count) showing that water used at poultry farms was of low microbiological quality. Five Disinfectants PHMB20% (.75ml/lit, 1.5ml/lit, 3.0ml/lit), PHMB11% (1.5ml/lit, 3.0ml/lit, 6ml/lit), 0.2% chlorine dioxide (0.1ml/lit , 0.2ml/lit, 0.4ml/lit) Glutral 9.8%(1.5ml/lit, 3.0ml/lit, 6ml/lit), organic acid(1.5ml/lit, 3.0ml/lit, 6ml/lit) were used and they resulted in log reduction of TVC by PHMB20% (5.83±4.36, 6.14±3.98, 9.35± 0.68), PHMB11% (9.42±0.21), 0.2% chlorine dioxide (2.45±0.97, 3.19±0.73, 6.33±0.80 ) Glutral 9.8%(6.87±1.00, 9.73±1.00,9.73±1.00), organic acid(4.75±1.21, 6.62±1.26, 6.90±1.15).PHMB20%,PHMB11%, Glutral 9.8% and organic acid were effective at normal dose, while 0.25 chlorine dioxide was effective at normal dose against at normal dose. Log reduction in Coliform count at half, normal and double dose by PHMB20% (6.52±3.33, 6.96±2.46, 7.96±0.98), PHMB11% (7.89±1.01), 0.2% chlorine dioxide (3.65±0.73, 5.08±0.98, 6.27±0.97) Glutral 9.8%(8.48±0.99), organic acid(5.18±1.21, 5.93±1.26,6.46±1.15±) . PHMB20%, PHMB11%, 9.8% Glutral, organic acid were effective against coliform bacteria at half dose while 0.2% chlorine dioxide was effective at normal dose. Glutraldehyde was effective at normal dose amongst all disinfectants against Total viable bacteria and coli form bacteria.

Water is an important constituent for poultry. Poor hygienic conditions of water are health hazard for poultry. Many outbreaks are caused by consuming poor quality water.. Fifty water samples from different broiler farms in and around Lahore were collected from drinkers in sterile containers. Bacterial load was assessed using total viable count and coliform count. The counts were above the threshold level (50cfu/ml for coliform and 100cfu/ml for total viable count) showing that water used at poultry farms was of low microbiological quality. Five Disinfectants PHMB20% (.75ml/lit, 1.5ml/lit, 3.0ml/lit), PHMB11% (1.5ml/lit, 3.0ml/lit, 6ml/lit), 0.2% chlorine dioxide (0.1ml/lit , 0.2ml/lit, 0.4ml/lit) Glutral 9.8%(1.5ml/lit, 3.0ml/lit, 6ml/lit), organic acid(1.5ml/lit, 3.0ml/lit, 6ml/lit) were used and they resulted in log reduction of TVC by PHMB20% (5.83±4.36, 6.14±3.98, 9.35± 0.68), PHMB11% (9.42±0.21), 0.2% chlorine dioxide (2.45±0.97, 3.19±0.73, 6.33±0.80 ) Glutral 9.8%(6.87±1.00, 9.73±1.00,9.73±1.00), organic acid(4.75±1.21, 6.62±1.26, 6.90±1.15).PHMB20%,PHMB11%, Glutral 9.8% and organic acid were effective at normal dose, while 0.25 chlorine dioxide was effective at normal dose against at normal dose. Log reduction in Coliform count at half, normal and double dose by PHMB20% (6.52±3.33, 6.96±2.46, 7.96±0.98), PHMB11% (7.89±1.01), 0.2% chlorine dioxide (3.65±0.73, 5.08±0.98, 6.27±0.97) Glutral 9.8%(8.48±0.99), organic acid(5.18±1.21, 5.93±1.26,6.46±1.15±) .
