What is the standard water-to-feed consumption ratio for brown layers at different ambient temperatures?

Monitoring the water-to-feed ratio is a highly effective, real-time diagnostic tool for farm managers. At thermoneutral temperatures (18°C to 22°C), a brown layer hen consumes about 200 to 240 ml of water for every 110 to 120g of feed. When temperatures rise above 30°C, feed intake drops immediately to reduce metabolic heat production, while water intake increases dramatically to support evaporative panting and prevent dehydration. A sudden spike in water consumption without a temperature rise can signal intestinal infections (like Enteritis) or high feed salt levels. Conversely, a drop in water intake leads to an immediate drop in lay rate and smaller egg sizes. Farmers can find water management algorithms in the Poultry Encyclopedia, source automated waterers and RO filters on Poultry Plaza, check daily prices on Poultry Rates, and trade stocks on Murghi Mandi.
