Abstract |
A total number of 150 male Ross 308 day-old broiler chicks were used to
assess the effects of magnetizing drinking water on broilers
performance.
Thus, an experiment was conducted as 3 treatments with 5 replicates of
10 birds each. The control birds consumed an ordinary tap water. One
minute and three hours magnetized water by 0.65 Tesla magnetic field was
the second and the third experimental treatments.
Magnetiziation of drinking water did not have a pronounced effect on
the pH of crop and ileum contents,
thigh meat, gastrointestinal passage rate and excreta wetness at 21 day
of age. In addition, the pH of crop and thigh meat, pH and relative
humidity of litter contents and viscosity of jejunal supernatant at 41
day of age were not influenced by experimental treatments.
Magnetized water did not have a pronounced impact on apparent fecal
digestibility of dry and organic matter, and crude protein and
population of lactobacillus and coliforms in jejunal contents at 21 day
of age. The activity of aspartate aminotransferase (AST) in serum of
broilers that drank magnetized water significantly decreased, but
cholesterol, triglycerids, calcium, phosphorus,
and alanine aminotransferase (ALT) were not influenced by magnetized
water. The
relative weights and lenghts of intestinal parts at 21 and 41 day of age
were not significantly affected by treatments.
Muscularis thickness of small
intestine increased significatly by magnetized water both at 21 and 41
day of age. Villus height of jejunum significantly increased, but villus
width significantly decreased in birds that drank one-minute magnetized
water at 21 day of age. However villus surface area, crypt depth and
villus height to crypt depth ratio were not significantly affected by
experimental treatments at 21 and 41 day of age. Furthermore, weight,
volume, density, length, diameter, and ash of
right femur and tibia at 21 and 41 day of age were not influence by
megnetized water.
In conclusion, magnetized drinking water may influence liver function
enzyme and gut physiology in broiler chickens.
