| Abstract | ||
| Thirty black balady rabbit does aged 7 to 8 months old with averaged live body weight (LBW) 3125±60.49 g were used in a complete randomized design and were randomly assigned into three homogeneous groups (10 does in each). The first group was drinking tap water and regarded as control group (G1), while the second (G2) and third (G3) groups were drinking a magnetic treated water with 1200 and 3600 gauss, respectively. Rabbits in all groups were fed the commercial rabbit diet. Results showed that magnetic treated water (MTW) had better quality than those for tap water (TW) in conductivity, salinity and total hardness. Does in G2 drink magnetic water (1200 gauss) showed significantly (P<0.05) the highest live body weight (LBW) at mating and kindling, 1st service conception rate and the lowest number of services per conception, followed by those in G3 drink magnetic water (3600 gauss), while those in G1 drink tap water had the poorest values. Moreover, does in G2 recorded significantly (P<0.05) the highest average daily milk yield (ADMY) at different suckling intervals, followed by those in G3, while those in G1 had the lowest yield. Also, does in G2 significantly (P<0.05) the highest percentages of fat, protein, TS and SNF in milk followed by those in G3, while those in G1 had the lowest percentages. While, lactose percentage in milk of does in G2 and G3 was higher significantly (P<0.05) than in milk of does in G1. Does in G3 showed significantly (P<0.05) the highest concentrations of total protein, globulin, total lipids, triglycerides and LDL, and those in G2 had the highest glucose concentration, while those in G1 recorded the highest albumin, urea-N, HDL concentrations and ALT activity. The concentrations of creatinine and total cholesterol and AST activity was not significantly affected by magnetic water. Concentrations of IgG and IgM in serum of does and their offspring were higher in G3, followed by G2, while they lower in G1, but the differences were not significant. Does in G2 showed significantly (P<0.05) the highest litter size during the different suckling intervals, followed by those in G3, while those in G1 had the lowest values. However, mortality rate revealed the opposite trend. Group G2 showed significantly (P<0.05) the highest weight and weight gain of litter and bunnies followed by G3, while G1 had the lowest values. Feed intake and feed cost was nearly similar for different groups. While, total cost (feed cost plus magnetic water cost) was higher significantly (P<0.05) for G3 followed by G2, while G1 had the lower cost. Group G2 showed significantly (P<0.05) the highest price of weaning weight and net revenue followed by G3, while G1 had the lowest values. | ||
