Avaliação econômica da adição de blend enzimático em dietas para suínos nas fases de crescimento e terminação

Abstract

In pig production, feed accounts for approximately 70% of total production costs, with corn andsoybean meal being the main contributors to this expense. Although widely used, theseingredients contain antinutritional factors such as non-starch polysaccharides andoligosaccharides, which reduce digestibility, increase intestinal viscosity, and impair animalperformance. One strategy to mitigate these effects is the addition of exogenous enzymes,which break down the complex structures of plant ingredients, enhancing nutrient utilizationand allowing for the formulation of diets with lower energy density. In this context, this studyaimed to evaluate the partial net revenue and identify the factor with the greatest impact on theeconomic viability of adding an enzymatic blend to diets for growing and finishing pigs. Dataon feed intake and animal weight were obtained from an experiment with 36 castrated malepigs distributed into three treatments: CON: control diet; RED5%EM: diet with approximately5% energy reduction compared to the control; and RED5%+blend: diet with approximately 5%energy reduction and the addition of the enzymatic blend. Based on feed intake, animal weight,feed cost, and pig price, partial net incomes were calculated for the period from January toDecember 2023. Monthly simulated partial net income values were submitted to multiple linearregression analysis considering the average monthly prices of corn, soybean meal, wheat bran,soybean oil, and live pig price (R$/kg), adjusted by block and treatment, using the stepwiseregression procedure. The RED5%+blend treatment showed higher partial net incomecompared to RED5%EM and similar results to the control in most months, demonstrating ahigher economic return per animal. It is concluded that the inclusion of the enzymatic blend indiets for growing and finishing pigs results in improved partial net revenue, and that the mainfactors impacting the revenue obtained from the animals are the costs of corn, soybean meal,and the pig price.
