The project was planned to study the effectiveness of cooling through surface wetting on the performance of 384 Single Comb White Leghorn layers maintained in cages during summer season. Group A was kept as control where no water was sprayed for surface wetting of layers. Group B was sprayed with water once daily at 12.00 noon, group C was sprayed twice a day at 12.00 noon and at 2.00 p.m. and group D was sprayed thrice a day at 12.00 noon, 2.00 p.m. and at 4.00 p.m. The egg production was improved by 3.368 and 4.882 per cent in birds where water was sprayed once as compared to control and twice daily. Egg production was better 1.187 per cent where water was sprayed 3 times a day than those of twice. It was observed that thrice sprinkling was 0.89, 3.374 and 4.881 per cent more efficient in feed conversion ratio as compared with twice, once and control, respectively. Control group had 0.303, 2.185 and 2.185 per cent less final body weight than group of once, twice and thrice. , |
