Chemical evaluation of poultry drinking water at sharkia governorate

الملخص EN

This study was conducted to evaluate the chemical constituents of poultry drinking water from main water supplies and drinkers of broiler and layer poultry farms at Sharkia Governorate.

For this purpose, a total of 100 water samples comprising 49 main water supply samples and 51 drinker's water samples were collected from 24 broiler farms and 25 layer farms located at different regions of Sharkia Governorate.

The collected samples were examined chemically for determination of PH, ammonia, nitrite, nitrate, chloride, sulphate, total hardness, lead and cadmium concentrations.

The results revealed estimation of the corresponding elements in main water supplies with the following mean concentrations : PH (7.32 ± 0.04), ammonia (0.14 ± 0.02 mg / L), nitrite (0.03 ± 0.005 mg / L), nitrate (5.09 ± 0.52mg / L), chloride (113.35 ± 8.22 mg / L), sulphate (98.1 ± 14.36 mg / L), total hardness (112.86 ± 6.27mg / L), Lead (0.27 ± 0.037 mg / L) and cadmium (0.0004 ± 0.0001 Mg / L).

Whereas, the mean values of these elements in water of drinkers were 7.16 ± 0.14 , 0.65 ± 0.07 mg / L, 0.12 ± 0.01 mg / L, 24.50 ± 2.14 mg / L, 193.1 ± 10.22mg / L, 200.58 ± 31.88 mg / L, 420.11 ± 31.39 mg / L, 0.34 ± 0.0396 Mg / L, and 0.005 ± 0.004 mg / L, respectively.

Comparing the values of such chemical elements in main water supplies and drinker's water clarified higher significant values of most parameters in water of drinkers and this reflect the vital role of birds in water contamination.

Moreover, investigation of examined water samples in relation to its source revealed higher nitrite, nitrate, chloride and total hardness in ground water than treated surface one.

On contrast, treated surface water showed higher PH, ammonia, sulphate, lead and cadmium than ground water samples.

In addition, water from drinkers of broilers had higher concentration of all chemical parameters than the water from drinkers of layers.

The influence of determined chemical elements on poultry & public health and hygienic measures to protect poultry drinking water from contamination were fully discussed.
