Abstract Twenty commercial White Leghorn layer farms in and around Namakkal area, which were getting drinking water either from bore well or open well were selected for this study. Water samples were collected at two weeks interval for 20 weeks period and analysed. The results revealed that except the sulphate and total dissolved solids, chloride, nitrate, nitrite and total hardness were comparatively higher in open well tJum borewell water. Though the openwell waterhad higher levelofsalts,the saltlevels in boththe water sources were within the safer level except nitrite. Bore well water given layers recorded better HDEP, HHEP and feed efficiency when compared to layers getting water from open well. It is concluded that in Nama1dcal poultry pocket layer farms with bore well water perfonned better than the layer farms with open well water as drinking source. Top Key words Water quality, egg production, feed efficiency. Top |
