“…The high dose of inulin (PR300) x rumen degradable protein interactions may have suppressed digestibility by affecting the fermentation parameters in the fermenter. Beecher et al (2013) stated that the highest and lowest organic matter digestibilities of various PR cultivars were 75.2 and 69.6%, respectively. The findings of the present study for organic matter digestibility in all groups were similar to those of Beecher et al (2013).…”

Effects of various inulin levels on in vitro ______________________________________________________________________________________ AbstractThe aim of this study was to investigate the effects of various inulin levels on in vitro true dry matter digestibility (IVTD DM ) and in vitro neutral detergent fibre digestibility (IVTD NDF ) of corn silage (CS), perennial ryegrass (PR), and common vetch/oat hay (VO). Inulin was added to the fermenter at concentrations of 0 (CSC, PRC, VOC), 100 (CS100, PR100, VO100), 200 (CS200, PR200, VO200), and 300 (CS300, PR300, VO300) mg/litre of total culture fluid using an in vitro Daisy II incubator. Each fermenter contained 1600 ml buffer solution and 400 ml rumen fluid.

“…The effect of sampling date on grass composition was not unexpected, given the normal changes that take place in grass quality over the season (Beecher et al ., ). Herbage quality was high, however, and the composition similar to that offered in a number of recent grazing studies (Vance et al ., ; Jiao et al ., ; Purcell et al ., ).…”

The objective of this study was to examine the effect of sampling technique (pluck or cut), storage duration (immediate analysis, 24‐h or 48‐h), storage temperature (ambient or chilled) and storage conditions (air present, air excluded or breathable) on the composition of fresh grass sampled from a sward managed to simulate grazing. Treatments were repeated across four sampling dates, with grass samples stored in grip seal bags prior to analysis using near‐infrared reflectance spectroscopy. Grass sampled by ‘pluck’ had a higher crude protein and ME content, and a lower acid detergent fibre (ADF) content, compared to that sampled by ‘cut’. Grass stored for 48 h had a lower water soluble carbohydrate (WSC) and ME content and a higher ADF content than for immediate analysis. Samples stored for 24 h did not differ from immediate analysis. Grass stored at ambient temperature had a lower WSC and ME content compared to immediate analysis. Grass stored under ‘breathable’ conditions had a lower ME content and higher ADF content than immediate analysis or samples stored with air present or air excluded. It is recommended that grass for analysis should be sampled by cutting, stored chilled (4°C) in a sealed bag to minimize exposure to oxygen and analysed within 24 h of harvest.

“…Los raigrás tetraploides presentan un mayor requerimiento de nutrientes, debido a la mayor síntesis de forrajes y valor nutricional respecto a los diploides (Beecher et al, 2013). Sin embargo, cuando se presentan limitaciones en la disponibilidad de nutrientes edáficos y ambientales, los raigrás diploides pueden presentar una mayor respuesta productiva respecto a los tetraploides (Posada et al, 2013).…”

ResumenLos sistemas de lechería en Colombia se basan en el uso de praderas, por lo cual es necesario determinar la respuesta de los forrajes bajo diferentes condiciones ambientales. El objetivo del presente trabajo fue evaluar el establecimiento y la producción de raigrás perennes y tréboles en dos regiones del trópico alto colombiano. Se evaluaron cinco raigrás perennes (tres diploides y dos tetraploides) y tres tréboles (dos rojos y uno blanco) en Tuta, Boyacá y Mosquera, Cundinamarca. Se establecieron parcelas de 8 m 2 de cada especie con tres repeticiones. Las variables de establecimiento fueron evaluadas quincenalmente durante los primeros cinco meses. Las variables de producción y calidad nutricional fueron evaluadas en temporada de lluvia (abril y mayo) y de sequía (junio y julio). Se utilizó un diseño de bloques completos al azar con medidas repetidas, entre noviembre de 2015 y julio de 2016. Durante el periodo de establecimiento, se encontró una mayor cobertura y grado de adaptación en los raigrás y tréboles entre los días 45 y 60 y 105 y 150 en Tuta y Mosquera, respectivamente. La mayor edad provocó una disminución en la energía neta de lactancia (entre 7 y 15%) y un aumento en la producción diaria de materia seca por hectárea (entre 20 y 78 kg). El día de evaluación presentó una mayor influencia respecto a la variedad y la época de lluvias sobre las variables de establecimiento y producción evaluadas en raigrás y tréboles en trópico alto colombiano.Palabras clave: ganado de leche, sistema agropastoril, plantas forrajeras. AbstractColombian dairy systems are based on grasslands; therefore, it is necessary to define forages response under different environmental conditions. The objective of this study was to assess the establishment and production of five perennial ryegrass and three clovers into two regions of Colombian highlands (Tuta, Boyacá and Mosquera, Cundinamarca). Three 8 m 2 plots of each species were established. Establishment variables were evaluated twice a
