Summary
Present study was planned to evaluate quality of water consumed by livestock. Fifty water samples were collected from dairy farms in and around
Rawalpindi/Islamabad. Collected water samples were put forth for analysis of different physical and chemical parameters. The mean values of parameters such as pH, Electric Conductivity, Turbidity, Total Dissolved Solids (TDS), Total Suspended Solids (TSS), total hardness, Calcium, Magnesium, Nitrates and sulphates were 7.57, 857.53 μs, 1.16 NTU, 625.38 mg/L, 324.15 mg/L, 216.15 mg/L, 49.32 mg/L, 166.82 mg/L, 4.46 mg/L and 13.30 mg/L respectively and thus found within safe limits. Heavy metals such as Cu, Ni, Zn, Pb, Cr, and Cd detection was done by using atomic absorption spectrometry and mean values were 0.03 mg/L, 0.03 mg/L, 0.03 mg/L, 0.12 mg/L, 0.29 mg/L and 0/01 mg/L respectively. In bacteriological study, Most Probable Number (MPN) technique was used to determine the coliform counts of water samples. This involved the presumptive test using MacConkey broth with durhan tube, confirmatory test using Eosin Methylene Blue (EMB) agar. Total coliform counts revealed presence of bacterial contamination <100MPN/100 ml in water samples. To eliminate the microbial population, an acidifier (named S.O.S. Liquid Nutega, Spain) dosage trial was also done. It was revealed that acidifier at first inclusion level 10 μl / 50 ml water
sample effectively reduced (64.50%) microbial population. Furthermore, at second inclusion level 20 μl / 50 ml water sample, it nearly eliminated (99.98%) bacterial population.

Dear Sir,
I read the abstract and I found that this article will be useful for me to conduct trials on use of acidifiers in poultry. Sir, I want this article for study purpose. If possible kindly send this article to my email.
Regards.
