Responses of the Fertility, Semen Quality, Blood Constituents, Immunity and Antioxidant Status of Rabbit Bucks to Type and Magnetizing of Water

Abstract

this work aimed to test the responses of the fertility, semen quality, blood constituents, immunity and antioxidant status of rabbit bucks to water type (e.g., tap water and well water) and magnetizing of water exposed or unexposed to a magnetic field of ≈4000 gauss. The experimental design was factorial 2 (type of water, e.g. tap vs. well water) × 2 (magnetic treatments, e.g. unexposed vs. exposed to magnetic field) using forty mature V-line rabbit bucks randomly distributed to four groups of 10 animals each. The rabbit bucks were provided free access to the water and same diet. well water had lower quality than tap water, i.e. higher ph, conductivity, salinity, calcium, magnesium, and total hardness. water magnetizing had less effect on tap water than on well water (e.g. on ph, conductivity, salinity, calcium, magnesium, total hardness and dissolved oxygen). bucks that consumed tap water showed better semen quality, metabolic profiles and immunity than those that drank well water. Magnetized water significantly increased body weight, feed intake, reaction time, fertility, sperm concentration, mass motility and total live sperm of bucks consuming well water and tap water. The improvements in fertility and semen quality concurred with significant increases in testosterone hormone, immunoglobulin a, antioxidant enzymes, and with decreases in lipid peroxidation biomarker malondialdehyde and thiobarbituric acid-reactive substances. in conclusion, well water induced a significant decrease in semen quality and hence fertility of males. whereas magnetic treatment improved water quality, semen quality, blood picture and antioxidant status and hence buck fertility. key words: rabbit bucks, magnetic water, semen quality, physiological traits, immunity Environmental factors had effects on productive and reproductive performance of farm animals and resulted in a decrease in semen quality and fertility of males (Mann and Lutwak-Mann, 1981; Rasooli et al., 2010; Attia et al., 2013

Magnetized drinking water improves productivity and blood parameters in geese

“…Exposed water showed considerable changes in its physicochemical characteristics, such as pH (8.69 vs 7.37 %), conductivity (9.83 vs 5.24 %), salinity (2.47 vs 9.69 %), Na (6.78 vs 15.78 %), Ca (15.02 vs 20.58 %), Mg (15.81 vs 20.08 %), Cl (27.05 vs 18.60 %), and dissolved oxygen (44.09 vs 37.07 %) of WW and TW, respectively, as published by Attia et al (2015). According to the literature, exposing water to magnetic fi elds changes its properties, with a slightly alkaline pH (>7), higher mineral (higher salinity) and oxygen contents, and lowers germs, which fulfi ls animal requirements for water quality (Mg-Therapy, 2000).…”

“…The negative effect on MPG matched the lower number of hatched goslings due to the low fertility and hatchability of fertile eggs, and as previously mentioned, could be attributed to decreased water consumption. Poor water quality has been shown to decrease animal performance and induce health risks (Wahaab and Badawy, 2004;Attia et al, 2013;2015). Moreover, De Blas (2013) reported that compositional alterations in the gut are a possible cause of gut disorders, retarded growth, and health problems in animals.…”

“…In addition, Lin and Yotvat (1989) showed that milk yield increased when dairy cattle drank magnetized water. El-Hanoun et al (2013) observed an improvement in productive and reproductive performance of doe rabbits, and Attia et al (2015) observed an improvement in buck rabbit performance after receiving magnetized drinking water. Nonetheless, Sargolzehi et al (2009) found that exposing water to a magnetic fi eld produced no signifi cant eff ect in performance, carcass composition, blood constituents or milk nutrient profi le of lambs and goats.…”

“…In these areas, water quality is poor, presenting a major challenge to poultry farming (Attia et al, 2013;2015). Total dissolved salts, salinity, and nitrates are among the major factors determining the suitability of a particular water source for poultry (Morsy et al, 2012).…”

“…The infl uence of magnetic treatment for improving agriculture has been studied with major emphasis on plants, while research on animal productivity has received less attention (Hozayn and Abdul Qados, 2010;Attia et al, 2015). Magnetized water improves health by inhibiting bacterial growth, while reducing pain, swelling, and weakness (Verma, 2011).…”
