The study was conducted to evaluate the effects of magnetized water (2000 Gauss)
and season on semen and blood constituents in rabbit bucks. A total number of 32 New Zealand White
(NZW) rabbit bucks were used in the experimental work during winter and summer seasons (16 in
each). In each season animals were divided into 2 sub-groups (8 bucks in each). One sub group
received magnetized water (MW) and the other received non magnetized water (NMW). Semen was
collected weekly for 8 weeks using an artificial vagina. Reaction time (RT) was recorded during
semen collection. Blood was collected and some common parameters were assayed. Semen was
evaluated for ejaculate volume, mass motility, progressive motility, sperm concentration, live, dead
and abnormal spermatozoa. Results showed that electrical conductivity, dissolved oxygen content,
salinity, particularly sodium and calcium contents, and pH value in MW increased as compared to
NMW. Ejaculate volume, mass motility, progressive motility, reaction time and sperm concentration
were not affected by season, while live, dead and abnormal spermatozoa were affected (P≤0.001).
Bucks consumed MW showed significantly improved (P≤0.001) physical semen characteristics in
terms of increasing mass motility, progressive motility, sperm concentration, live spermatozoa and
ejaculate volume as well as reaction time compared to NMW. Dead and abnormal spermatozoa were
significantly (P≤0.001) lower in bucks received MW than in NMW. Consumption of MW led to an
increase of red blood cells (RBC), hemoglobin (Hb) and hematocrit (HCT) as compared to NMW.
However RBC, Hb and Platelet count (PLT) were considerably higher (P≤0.001) in winter than in
summer. In general as, magnetic treatment improved water quality, physical semen characteristics and
blood constituents in rabbit bucks.
