Effect of Magnetized Water on Productive Performance and Digestive System of Japanese Quail تأثیر الماء الممغنط علی الأداء الإنتاجی والجهاز الهضمی للسمان الیابانی

Four hundred and five unsexed Japanese quail were divided randomly to three treatments with three replicates for each treatment. In two-way analysis experimental design to compare between effect of sex and magnetized water (MW) and tap water on productive performance ,feed consumption (FC), feed conversion ratio (feed/gain) (FCR), relative weights of digestive tract, liver, gizzard, proventriculus, spleen and heart of Japanese quail. The first group drank normal tap water as a control group. The other groups drank the magnetized water which exposed to electric magnetic field with forces: 10000 gauss (1Tesla) (MW1) as second group or 20000 gauss (2 Tesla) MW2 as third group. (MW2). The most important results as follow: MW1 caused highly significant increase in LBW and LBWG and had better FCR compared to the other groups of Japanese quail. The birds that drank magnetized water were lower FC than those drank ordinary water. There was significant increase in LBW, LBWG and FC of female compared with male, and the females owned the best values of FCR during the all periods compared to males. Significant differences in rectal length at 35 days of age were found. Insignificant differences in lengths of the digestive system at all ages of study were found expect rectal length at 35 days of age was significant (P≤0.05) for treatments and the control group recorded highly length than magnetized water groups. It could be concluded that productive performance and digestive system of Japanese quail were improved due to offering MW1 was adequate to provide the beneficial effects. [T1]   [T1]اعاده صياغه
