| Abstract | ||||
| This study aimed to evaluate the influence of magnetic process of water such drinking tap water by exposed to magnetic field (at levels of 1200 and 3600 Gauss on growth performance of rabbits. Forty eight growing black Balady rabbits were randomly distributed into three similar groups of male and female (16 each), using complete randomized block design. Treatments of feeding trial included tap water without or with magnetic exposure (0 (control), 1200 and 3600 Gauss) for G, G1 and G2 treatments, respectively. Results showed that magnetic treatment induced greater effect on magnetic treated water in terms of pH, conductivity, salinity, and dissolved oxygen. Rabbits consumed low level magnetic water G1 had higher insignificantly final body weight and weight gain at (14 weeks) than those of control (G) and the higher level magnetic water (G2).Feed intake as DM was nearly similar in all groups. Feed conversion was improved (P<0.05) insignificantly for rabbits drank magnetic water (G1) than that of G groups and significantly than those of G2 group. Results showed that magnetic treatment did not affect nutrient digestibility coefficients and feeding values based on control. Group G1 had increased insignificantly in fasting, total edible parts and empty carcass weights than those of other groups. Dressing percentage was insignificant higher with G1 and significant higher with G2, than that of control G. While weights of edible giblets (heart, liver and kidney) did not affected significantly by experimental treatments. Concentrations of blood metabolites were nearly similar in all groups, except concentration of glucose which increased significantly due to both tested treatments. While ALT decreased (P<0.05) significantly by G2 than that of other groups. Counts of red blood cells and white blood cells were nearly similar in all groups. Also, no significant differences in respect of haemoglobin and haematocrit concentrations and PCV% as well among treatments. Rabbits received magnetic water at G1 were lower (0<0.05) significantly regarding total volatile fatty acids than other groups. Specifically, gram negative bacteria (E.coli.) and anaerobic bacteria numerically were decreased (P<0.05), while gram-positive germs (Lactobacillus) increased (P<0.05) significantly with magnetic treated water than those of control treatment. It could be concluded that magnetizing tap water by the two levels (1200 and 3600 Gauss) led to an improvement respecting growth performance of rabbits. | ||||
