Sažetak
Studies were conducted on two farms for housing of Isa Brown hybrid hens, matched by microclimatic parameters and layer mash. Different quality of drinking water was the only variable which may have influenced the health and productivity of hens. Organoleptic, physicochemical and bacteriological parameters of drinking water were compared between a control farm supplied with appropriate town water and experimental farm supplied with inappropriate underground water. Electrical conductivity (3 037 &plusmn ; ; 1 714 &micro ; ; S/cm), and the concentration of chloride (612.8 &plusmn ; ; 152.2 mg/l) and sodium (466.3 &plusmn ; ; 115.6 mg/l) were significantly increased in the water supplied to the experimental group as compared to the control group of hens, indicating the former to be saline water. Other organoleptic, physicochemical and bacteriological parameters also exceeded the allowed limits. Productivity indicators, such as egg production (%), eggshell weight (g), eggshell thickness (&micro ; ; m) and eggshell defects (%) were poorer in the experimental group, which could have been ascribed to the use of saline drinking water. However, statistical analysis revealed no statistically significant differences in egg and shell weight, and shell thickness (p > 0.05).
