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 c...

The aim of this study was to evaluate the effect of the inclusion of Azolla on the diet of Japanese quails on voluntary intake, apparent nutrient digestibility and egg production. A total of 240 16-week old quail on the first third of egg laying were used. The birds were housed in 24 raised cages (10 per cage). A completely randomized design was used with four treatments: T1: 0%, T2: 5%, T3: 10% and T4: 15% inclusion of Azolla in the diet. Voluntary nutrient intake was higher in Azolla treatments (p<0.05). The lowest egg yield g/bird/day1 was in T4 (p<0.0001) and the best feed conversion was in T1 and T2 (p<0.0001). The apparent digestibility of dry matter and organic matter showed no significant difference between treatments. The highest crude protein digestibility was in T1 (46.1%) and T2 (44.5%) (p<0.0001) and the highest for digestibility of neutral detergent fibre was in...

El objetivo de esta investigación fue evaluar el efecto de la inclusión de Azolla en la dieta de codornices japonesas sobre el consumo voluntario, digestibilidad aparente de los nutrientes y producción de huevos. Se utilizaron 240 codornices de 16 semanas de edad iniciando el primer tercio de postura. Las aves se alojaron en 24 jaulas elevadas (10 aves por jaula). Se utilizó un diseño completamente al azar con cuatro tratamientos: T1: 0%, T2: 5%, T3: 10% y T4: 15% de inclusión de Azolla en la dieta por 60 días. El consumo voluntario de nutrientes fue mayor en los tratamientos con Azolla (p<0.05). El menor rendimiento de huevos g/ave/día1 fue en T4 (p<0.0001) y la mejor conversión alimenticia fue en T1 y T2 (p<0.0001). La digestibilidad aparente de la materia seca y materia orgánica no mostró diferencia significativa entre tratamientos. La mayor digestibilidad de prote...
