In this study, samples of water sources commonly used to prepareNewcastle disease vaccine in poultry were collected for analysis andexperimental vaccination trials. Water samples were collected fromdifferent areas; artesian well from Omdurman, shallow well from Elsagai,tap water was collected from Shambat, surface water from Elgiraif andcommercially bottled water.Water samples were tested to determine the quality of water usingthe main parameters; pH, conductivity, TDS, TSS, turbidity and salinity.Turbidity results showed great variation between the water sourcesexamined (artesian well, shallow well, tap water, surface water andbottled water) 4, 5, 0, 48 and zero N.T.U respectively for group A, B, C,D and E. TSS analysis resulted in0.8, 1.4, 0, 32 and zero mg\Lrespectively. PHlevels were between 6.6, 7.4, 7.21,7.18 and 7.32respectively. Conductivity results were 309, 928, 253, 253 and 207respectively. TDS results were148, 442, 120, 127, and 96 mg\Lrespectively. Salinity results 0.1 were equal for all groups.A number of 40 chicks in each group were vaccinated on the 14thday of age with LaSota vaccine of Newcastle Disease prepared in artesianwell (group A), shallow well (group B), tap water (group C), surfacewater (group D) and bottled water (group E). Blood was collected everyweek till the 5thweek and serum was tested for antibodies (Ab) againstND using hemagglutination inhibition (HI) test to determine the bestimmune response.Based on the experiment results of the geo mean HI titers for groupE (bottled water) was the best group with regards to immune response.From the 1stto the 5thweek, Ab titers were 5.05, 6.47, 4.39, 3.95, andX3.52 log2respectively. The second best immune response was that ofgroup C (tap water) with 4.54, 6.38,4.52, 3.95 and 3.63 respectively.Group A gave 2.78, 4.41, 4.39, 4.38 and 3.52 log2respectively. Group Bresults were 3.52, 4.89,4.28, 3.32 and 3.26 log2respectively. On theother hand, group D results showed great difference from other groupswith 2.49, 3.95, 4.94, 3.14 and 2.88 log2respectively.The present study revealed great variations in water quality asmeasured by pH, conductivity, TDS,TSS and turbidity and in theimmune response when these five water sources were used to prepareLaSota vaccine in chickens. It isrecommended after this study to usebottled water or tap water to prepare drinking water vaccines in poultryfarms in Khartoum State.
