“…The alleviatory and physiologically beneficial effect of a high TDS was demonstrated when a TDS (NaCl) of 3000 mg/L improved the health and the reproductive status of Bonsmara cows exposed to potentially hazardous water (Elsenbroek et al, 2003).…”

“…The effects that these may have on an animal's physiology are determined by the WQC concentration, the ingestion rates and the agonistic or antagonistic interactions between the WQC. Total dissolved solids (TDS) may have an alleviatory effect on potentially hazardous WQC according to livestock type and site specific circumstances Elsenbroek et al, 2003). The effect of WQC on the production parameters of broilers was shown by Coetzee et al (2000a), Coetzee et al (2000b) and .…”

“…High concentrations of heavy metals may significantly decrease water intake (WI) as there is a clear indication of a linear relationship between increased concentration of the chemical mixture in the drinking water and decreased body weight of broiler breeder hens (Vodela et al, 1997). Sodium chloride (NaCl) is a potential alleviator based on the positive results obtained in mitigating chronic fluorosis and selenosis in cattle and sheep Elsenbroek et al, 2003), and the observations of high TDS concentrations in many rural communities.…”

Water quality constituents ingested through drinking water can affect the animal's physiology negatively and, through bioaccumulation in tissues, pose a biohazard to consumers. The study evaluated the effectiveness of a total dissolved solid (TDS) treatment as a possible alleviator of the accumulation of potentially hazardous chemical constituents (PHCC) in drinking water in broiler tissues. The trial design was 4 treatments x 7 replicates x 12 mixed Ross broilers per replicate. Treatments were T1 = TDS (NaCl) <500 mg/L + Br, As, Pb < 0.005 mg/L, T2 = TDS <500 mg/L + Br, As, Pb 0.1 mg/L, T3 = TDS 1500 mg/L + Br, As, Pb < 0.005 mg/L, T4 = TDS 1500 mg/L + Br, As, Pb 0.1 mg/L, administered through the drinking water from Days 1 to 42. Water intake and growth performance were recorded. Broilers were slaughtered, samples taken of liver, kidney, heart, thigh and breast tissue and analysed for accumulation of elements. TDS significantly (P <0.05) effected the accumulation of elements in some tissues. This confirmed the risk of ingesting PHCC through drinking water, and showed the potential of reducing the risk of accumulating PHCC in selected tissues by the controlled application of TDS in drinking water. However, the concentration attained within a short production period did not exceed the maximum allowable concentration for these elements in broiler tissue destined for human consumption.
