Abstract

This study aimed to investigate the effect of magnetic field on physicochemical properties of water and evaluating the effects of the magnetized water (MW) on the productive performance, liver enzymes, and histological structure of spleen and kidney of rabbits. Water samples were collected to determine pH and electrical conductivity (EC), and water structure was investigated by Transmission Electron Microscopy (TEM). Twenty-four weaned Rex rabbits, 21 d old, were allotted into two experimental groups: the first group was assigned as control, received regular tap water (TW), and the treated group, received MW, for 5 weeks. Productive traits were recorded weekly and at the end of the experiment, blood, spleen and kidney samples were collected for examinations. Results showed that pH and EC of MW were higher than those of TW. In addition, the arrangement MW cluster showed a unique alteration on the nano-scale. Growth performance indicators were similar in both experimental treatments, except FCR of the MW rabbits was better than that of the TW rabbits. The MW had no significant effect on plasma concentration of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and creatinine in growing Rex rabbits received MW in comparison with those received regular TW. Spleen histological structure of rabbits of both groups was normal. However, the epithelial cells lining renal tubules of kidneys of rabbits in MW group appeared large with basophilic nuclei in comparison with TW group. Conclusively, magnetic field altered the physicochemical properties of water. The MW may consequently increase blood glucose level and spleen weight , enhance kidney structure and improve FCR in growing rabbits. Moreover, more studies are still needed to know the benefits of providing the magnetized water to animals. © The Author(s) 2024
