| description | The aim of this work was to characterize chemically and nutritionally the cake generated from the extraction of oil from the sacha inchi seed, and to evaluate the in vitro digestibility and degradability parameters of ruminant diets with different inclusion levels. The determination of the dry matter (DM), crude protein (CP), ether extract (EE), fibre in neutral detergent (NDF) and fibre in acid detergent (FDA) of the sacha inchi cake was conducted. Four diets based on corn silage, corn grain, glycerol, soybean cake and sacha inchi cake were evaluated as protein substituents for soybean cake, in four proportions (0, 5, 10 and 15%). An amino acid profile and the digestibility and degradation kinetics of DM were performed. For the degradability study, samples were taken at 0, 3, 6, 12, 24, 48 and 96 hours to determine the disappearance of DM. The cake showed a concentration of 40.8% CP. The lysine and threonine values were 2.28 and 1.89 g/100 g sample, respectively. The in vitro digestibility of the diets did not show significant differences between them. The ruminal degradation kinetics of the diets was similar except at 0 and 96 h, showing a slight decrease between 0 and 6 h, to later increase in all diets. The results indicate that sacha inchi cake is a good feed alternative in ruminants and represents an important option as a substitute for soybean cake as a protein source. |

El objetivo de este trabajo fue caracterizar química y nutricionalmente la torta generada de la extracción de aceite de la semilla de sacha inchi, y evaluar parámetros digestibilidad y degradabilidad in vitro de dietas para rumiantes con diferentes niveles de inclusión. Se hizo la determinación de la materia seca (MS), proteína cruda (PC), extracto etéreo (EE), fibra en detergente neutro (FDN) y fibra en detergente ácido (FDA) de la torta de sacha inchi. Se evaluaron cuatro dietas a base de ensilaje de maíz, grano de maíz, glicerol, torta de soya y torta de sacha inchi como sustituyente proteico de la torta de soya, en cuatro proporciones (0, 5, 10 y 15%). Se realizó un perfil de aminoácidos y la digestibilidad y cinética de degradación de la MS. Para el estudio de la degradabilidad se tomaron muestras a las 0, 3, 6, 12, 24, 48 y 96 horas para determinar el desaparecimiento de la MS. La torta mostró una concentración de 40.8% de PC. Los valores de lisina y treonina fueron de 2.28 y 1.89 g/100 g muestra, respectivamente. La digestibilidad in vitro de las dietas no mostró diferencias significativas entre las dietas. La cinética de degradación ruminal de las dietas fue similar en todos los horarios excepto a las 0 y 96 h, mostrando un leve descenso entre las 0 y 6 h, para luego aumentar en todas las dietas. Los resultados indican que la torta de sacha inchi es una buena alternativa alimenticia en rumiantes y representa una opción importante como sustituto de la torta de soya como fuente proteica.
