Water is the most critical nutrient for cattle, yet feedlot systems sometimes fail to provide adequate access, leading to significant welfare and productivity consequences.
Inadequate water access in feedlots causes dehydration, heat stress, reduced growth, and increased disease susceptibility. Competition at water troughs means subordinate animals may not drink enough, creating welfare disparities within groups. Water quality issues — algae, contamination, or high mineral content — reduce voluntary intake. During extreme heat events, insufficient water can be fatal. Welfare standards now increasingly specify minimum trough space and water flow rates per animal.
