Two trials were conducted to determine the normal feed and water consumption of broiler chicks from placement to 21 days of age. Daily intakes were determined on straight-run chicks. Mash feed and water were supplied ad libitum. Prediction equations for feed and water consumption on a per chick basis were generated:

F_D = . 37 + 3.546 (A)

F_C = 9.66 + . 5056 (A) + q. 8355 (A²)

W_D = 9.73 + 6.142 (A)

W_C = 21.41 + 9.064 (A) + 3.193 (A²)

Where F_D = daily feed intake (grams); F_C = cumulative feed intake (grams); W_D = daily water intake (grams); W_C = cumulative water intake (grams); and A = age (days). Results are intended to establish a baseline by which researchers can calculate the amount of feed and water that will be consumed daily and cumulatively during the starter period.

Key Words: Feed consumption • water consumption • starter diet • prediction equations
