Water is an essential nutrient for poultry and any deviation in water intake indicates issues related to nutrition, health and/or rearing environment. Williams et al. (2013) found that daily water consumption per bird increased over the course of time (1991 – 140.3 mL, 2000-2001 – 160.5 mL and 2010-2011 – 190.5 mL) and water to feed intake ratio (WI:FI) followed a similar pattern (1.90, 1.98 and 2.02, respectively). Thus, fast growing modern genetic strains of birds consume more water. The impact of dietary changes in water intake and WI:FI should be monitored regularly. For this purpose, a real time water measurement system was developed at the University of New England (Sharma et al., 2021). The system consisted of a 1.4-litre reservoir with a microcontroller to monitor water consumption. This paper summarises the results of five experiments to demonstrate the normal water consumption behaviour of broilers and the effects of nutrition on WI:FI and its relationship with feed efficiency.
