Water consumption
Assuming a 35 day live weight of 2.1 kg at a FCR of 1.55 = 3.255 kg feed (3255 gm) @ 1.75 x more water than feed = 5696 ml or cc or 5.696 litres of water/bird. At 2.0 x more water than feed = 6510 cc water = or 6.5 litres. In many instances the litter is wet by 14 days when the chick weighs only 480-500 gm and has consumed 500 gm of feed and @ 1.75 x more water = 0.5 x 1,75 = 875 gm feed 0r (0.875) L of water. @ x 2.0 = 1000 ml or 1.0 litres.
Why is this happening in so many instances that the litter is wet at 14 days? Indication would have it that possibly better management has not kept pace with increases in bird performances on many poultry farms. Many houses that were erected 10+ years ago are still using the same bird numbers today, however with the genetic advancement alone (not to mention better nutrition), in hatchery vaccinations, gut health promoters, water soluble stress reduction packages to administer after water vaccinations and feed phase changes. Live weight/m2 has most probably increased by around 20+%.
