The acceptable standards for water quality in cattle drinking vary based on factors like local regulations and cattle management practices. General guidelines include avoiding excessive levels of contaminants, minimizing microbial contamination, maintaining pH within a suitable range (6.5-8.5), keeping total dissolved solids (TDS) below certain limits, and ensuring the absence of unusual odours or colours. Consulting local agricultural authorities, veterinarians, or extension services is crucial for specific regional guidelines.

The suitability of water for cattle depends on various factors, and specific guidelines may vary. However, elevated levels of coliform bacteria and E. coli can be concerning for drinking water.

Coliform bacteria and E. coli are indicators of fecal contamination, and their presence in water can pose health risks. High levels may indicate potential pathogens harmful to both animals and humans.
