The purpose of this quantitative study was to evaluate the effect of the addition of hydrolyzed soy lecithin (lipidol®) in feed for broilers Cobb 500, trying to solve technical limitations related to the profitability of the poultry exploitation process commonly generalized in the region. For this purpose, an experimental trial was implemented using a Completely Randomized Design with 4x3 factorial arrangement, factor A (lipidol addition levels: 0, 0.50; 0.75 and 1.0 kg/T of feed) and factor B (periods of use: 1-7; 1-15 and 1-21 days), with 12 treatments and 3 replicates on a total population of 288 chickens. The results indicate that the addition of different doses of hydrolyzed soy lecithin represented the increase in the weekly weight accumulated on chickens with the treatment (1 kg/T + 1-21 days) with 2963.91 grams (p=0.0001: 5% significance), daily weight gain (p=0.0001: 5% significance) with 69.56 grams, accumulated weekly feed consumption (p=0.0001: 5% significance) with 5643.26 grams, a lower percentage of mortality (1.41%) and a higher percentage of viability (98.59%). Finally, the cost-benefit analysis shows that the Lipidol® application (1 kg/T + 1-21 days) represents economic benefits in chicken production, registering a cost/benefit ratio of 1.15, which means a return of 15 cents for each dollar invested.
