Apparent ileal digestibility of the protein in broilers partially fed with sacha inchi (Plukenetia volubilis) cake. La Granja [online]. 2024, vol.40, n.2, pp.141-148.

This research was conducted at the experimental farm “Andil” of the State University of the South of Manabí, Cantón Jipijapa, Manabí, Ecuador, with the aim of evaluating the ethological behavior of the apparent ileal digestibility of dry matter (DM) and crude protein (CP) of Cobb 500 chickens in individual cages. 36 male chickens were used which were distributed in four treatments with different inclusion levels of sacha Inchi cake (SIC): T1 = control, without SIC, T2 = 10 % SIC, T3 = 20 % SIC and T4 = 30 % SIC. A Completely Randomized Design (DCA) was used for the statistical analysis, where each treatment had 12 repetitions, locating one animal per experimental unit. The results determined that chickens had a good response in quickly adapting to the cages, in addition to not reporting mortality and accepting food. The apparent ileal digestibility of DM did not show a difference between the treatments, while the N differed between the control group and the inclusion of T4 with 30 % (SIC), which was higher for the latter (85.20 vs 90.23 %). The results allow to conclude that the ethological behavior of the animals is not affected and good indices of ileal digestibility of DM and N are obtained when adding SIC in the diet of broilers.
