This paper titled "Optimizing the use of drinking water in rearing broilers in the initiation stage by using a linear scale trough", aimed to the validation of the use of a linear trough craft Broiler chicken boot stage (0-21 days), determine the production indices of broilers at initial stage (0-21 days), such as weight gain, feed conversion efficiency of utilization of drinking water and profitability, raised on two types of drinkers, cone and linear scale and evaluate drinking water consumption of broilers in the initial stage (0-21 days) in the tropical climate of San Martín, using two supply systems drinking water, drinking cone (Traditional) and linear scale trough (innovating).
