Incorporación de raíz de mandioca (Manihot sculenta) en la dieta de cerdos y su efecto sobre variables productivas

Abstract

In a pig feed program there is a wide variety of ingredients that can be used in the formulation of a diet. The objective of this work was to verify the convenience of using cassava root as a substitute for maize as an energy resource in pigs by measuring the variables of food consumption, live weight daily gain and feed conversion. A DCA was used in the assay. It lasted for 28 days, 7 for adaptation and 21 for measurement. The experiment included 12 animals and four diets: base diet (DB) with ground corn (71%) plus protein concentrate (29%); diets 33%, 66% and 100%: DB with replacement of 33, 66 and 100% of maize by cassava root, respectively. Statistical analysis was performed with the software InfoStat/P v.2011. From the analysis, for food consumption variables (1.63-DB, 1.56-33%, 1.53-66%, 1.44- 100%) and daily gain of body weight (0.42-DB, 0.40-33%, 0.39-66%, 0.36-100%) there were no differences between DB treatments, 33% and 66%, being the three cassava levels the same, while for the conversion (3,91-DB, 3.90-33%, 3.93-66%, 4.02-100%) there were no differences among the 4 treatments (p < 0.05). This leads to the conclusion that the inclusion of cassava root at different levels, except that for 100%, is a viable option to feed pigs.
