The objective of this work was to evaluate the inclusion of sunflower cake (SC) and the addition of enzymes in the ration of lightweight replacement pullets in the growth phase, as well as their effects on the variables feed consumption and conversion, productive performance, sexual maturity, egg quality at the beginning of the laying phase, and economic viability. Five hundred and forty pullets of the Hy-Line W-36 light line were used. The experimental design was completely randomized, in a 2×2+1 factorial arrangement, with two inclusion levels of SC (10 and 20%), with or without the addition of enzymes, and a control treatment. At the end of the growth phase (7 to 17 weeks age), 360 birds were transferred to the laying shed until their thirty-fifth week of age. There was no interaction between SC levels and enzymes, but an isolated effect of rations and enzymes was observed on feed consumption and conversion. There was a decrease in specific egg density and an interaction between the factors for this variable, but without affecting productive performance. The inclusion of up to 20% SC in the rations does not affect bird performance in both evaluated phases; however the use of 20% SC with enzymes is more economically viable. |
