ABSTRACT:
The aim of this study was to evaluate the effect of sorghum grain supplementation on ruminal pH and NH3-N concentration of wethers consuming a fresh temperate pasture (Lotus corniculatus) in metabolism cages. Sixteen Corriedale x Milchschaf wethers were fed temperate pastures ad libitum and were non-supplemented or supplemented with ground sorghum grain at 5, 10 or 15 g/kg of their body weight (BW). Rumen fluid samples were collected at 0, 1, 2, 3, 4, 5 and 6 h after supplementation through permanent tubes inserted in the rumen. Ruminal pH was measured immediately and NH3-N concentration was determined by direct distillation. Mean daily pH values for non-supplemented wethers and supplemented with 5, 10 and 15 g/kg of their BW were 6.45, 6.14, 6.09 and 5.43, respectively. Significant differences in pH were found between the 15 g/kg supplemented group and non-supplemented, 5 and 10 g/kg supplemented groups, while a trend was found between non-supplemented and 10 g/kg supplemented group. After 0 h, all mean pH values for the non-supplemented group were above 6.15, while values for the 10 and 15 g/kg supplemented groups were below 6.2 and 6.0, respectively. No differences in NH3-N concentration among groups (mean = 37.15 mg/100 mL), between time or interaction between time and treatment were found. There was a correlation between pH and NH3-N when all measurements were considered. Ground sorghum grain supplementation significantly reduced rumen pH when 15 g/kg of BW was provided to wethers fed temperate pastures, but it did not affect NH3-N concentration. MenosABSTRACT:

Este trabajo tuvo varios objetivos atendiendo las necesidades de las diferentes instituciones involucradas. Los objetivos específicos fueron: 1. Rehabilitación de pastizales en planicies de inundación comprendidas dentro del Área Protegida con Recursos Manejados Montes del Queguay, restituyendo algunos de los servicios ecosistémicos fundamentales del pastizal natural como es la producción de forraje, el hábitat para especies de fauna que utilizan el pastizal y la conservación del suelo y del agua. 2. Validación y divulgación de variedades forrajeras de especies nativas disponibles actualmente en el mercado o que van a estar disponibles a corto plazo. 3. Implementación de una alternativa tecnológica para productores que decidan convertir tierras de uso agrícola a uso pastoril permanente en el tiempo. 4. Implementación de un caso de estudio local en producción sostenible para estudiantes UTU. 5. Promoción de una red de trabajo inter-institucional (INC, SFRCJG, UTU, INIA, COPAGRAN y SNAP) y desarrollo de capacidades para trabajo conjunto buscando lograr los objetivos indicados previamente, para una producción sostenible. |
