Productive performance, ruminal degradation and in vitro gas production in sheep fed diets based on post-harvest residues of Chenopodium quinoa

Descripción del Articulo

The aim of the study was to determine the effect of the post-harvest residue intake of Chenopodium quinoa on the productive performance, apparent digestibility of dry matter (DM), ruminal degradation of DM and in vitro gas production in sheep. A group of 12 rams of 6 months were used to evaluate bod...

dc.description.none.fl_txt_mv The aim of the study was to determine the effect of the post-harvest residue intake of Chenopodium quinoa on the productive performance, apparent digestibility of dry matter (DM), ruminal degradation of DM and in vitro gas production in sheep. A group of 12 rams of 6 months were used to evaluate body weight gain and voluntary consumption for 75 days (15 days of adaptation) and in vivo digestibility in metabolic cages. A second group of 6 sheep over 8 months of age and rumen cannulated were used for the study of in situ ruminal degradation of DM using the nylon bag technique and for in vitro gas production. A randomized design with two treatments was used: T1: (95.8% Pennisetum clandestinum), T2: (75.8% P. clandestinum and 20% bran of C. quinoa). Voluntary intake in T2 was higher than in T1, but voluntary intake per kg PV0.75 showed no significant difference between treatments. The feed conversion was better in T2 versus T1 (7:91 to 9:29). The weight gain was higher in T2. The apparent digestibility of the DM did not show differences between treatments. In vitro gas production was lower in T2 with respect to T1. The parameters of ruminal degradation did not show differences between treatments. With respect to the rate of degradation (c) in percentage per hour no differences were observed between forages. It is concluded that forage residues of C. quinoa can be included in 20% of the diet of sheep for moderate body weight gain when using low nutritional quality pastures such as P. clandestinum.
El objetivo del estudio fue determinar el efecto de la ingesta de residuos pos-cosecha de Chenopodium quinoa sobre el comportamiento productivo, digestibilidad aparente de materia seca (MS), degradación ruminal de MS y producción de gas in vitro en ovinos. Se trabajó con un grupo de 12 carneros de 6 meses para medir la ganancia de peso y consumo voluntario durante 75 días (15 días de adaptación) y la digestibilidad in vivo en jaulas metabólicas. Un segundo grupo de 6 ovinos mayores de 8 meses y canulados para el estudio de degradación ruminal in situ de MS mediante la técnica de la bolsa de nylon y para la producción de gas in vitro. Se utilizó un diseño aleatorizado con dos tratamientos: T1: (95.8% Pennisetum clandestinum), T2: (75.8% P. clandestinum y 20% afrecho de C. quinoa). El consumo voluntario en T2 fue mayor que en T1, pero el consumo voluntario por kg PV0.75 no mostró diferencia significativa entre tratamientos. La conversión alimenticia fue mejor en T2 frente a T1 (7:91 a 9:29). La ganancia de peso fue superior en T2. La digestibilidad aparente de la MS no mostró diferencias entre tratamientos. La producción de gas in vitro fue menor en el T2 con respecto a T1. Los parámetros de degradación ruminal no presentaron diferencias entre tratamientos. Con respecto a la tasa de degradación (c) en porcentaje por hora no se observó diferencias entre forrajes. Se concluye que los rastrojos de forraje de C. quinoa pueden ser incluidos en un 20% en la dieta de los ovinos para ganancias moderadas de peso vivo al usar pastos de baja calidad nutricional como P. clandestinum.
