Phenology, yield and nutritional value of reed canary grass (Phalaris arundinacea) in dairy farms in the highlands of Costa Rica. Dry matter yield, nutritional value and phenology of reed canary grass (Phalaris arundinacea) were evaluated with three harvest ages (49, 70 and 91 days), during a year and a half, in a commercial dairy farm in the district of Santa Rosa de Oreamuno, Cartago Province. Average dry-matter yield was 3101 kg.ha-1.regrowth-1 period. Average nutritional value was 17.77% CP, 55.89% NDF, 35.93% ADF, 4.14% lignin and 66.87% IVDMD on dry-matter basis. Estimated energy content expressed as TDN, DE, ME, NEL (3X) and NEG was 63.07%, 2.76, 2.13, 1.31 and 0.81 Mcal.kg-1 of DM, respectively. CP fractioning of African star grass (Cynodon nlemfuensis) and perennial ryegrass (Lolium perenne), were compared with that of reed canary grass; the main contribution was obtained from the insoluble degradable fraction (B2+B3) in the temperate species, while african star grass had a higher contribution from the degradable fraction (A+B1). Average phenological stage of reed canary grass was 5.96 green leaves per regrowth and its leaf stage must be 5 to 6 leaves to optimize dry matter yield and nutritional value. Reed canary grass has been used in several dairy farms and has gained importance as an option that can withstand the weather conditions in the highlands of Costa Rica; olso, there are already companies importing sexual seed of this species.

Se evaluó la producción de biomasa, el valor nutricional y la fenología del pasto alpiste (Phalaris arundinacea) con 3 edades de cosecha (49, 70 y 91 días), a lo largo de año y medio, en una finca comercial de ganado lechero ubicada en Santa Rosa de Oreamuno, provincia de Cartago. La producción de biomasa promedio para el pasto alpiste fue 3101 kg.ha-1.corte-1 de MS. La composición nutricional promedio fue de 17,77% PC, 55,89% FDN, 35,93% FDA, 4,14% lignina y 66,87% DIVMS y su contenido energético expresado como TND, ED, EM, ENL (3X) y ENG fue 63,07%, 2,76; 2,13; 1,31 y 0,81 Mcal. kg-1 de MS, respectivamente. Se comparó el fraccionamiento de la PC de los pastos estrella africana (Cynodon nlemfuensis) y ryegrass perenne (Lolium perenne) con la del pasto alpiste, con el que las especies de clima templado presentan un aporte principalmente de la fracción insoluble degradable (B2+B3), mientras el estrella africana lo hace a nivel de la fracción degradable (A+B1). La edad fenológica promedio del pasto alpiste fue 5,96 hojas verdes por rebrote y su edad debe encontrarse entre 5 y 6 hojas para optimizar su producción de biomasa y valor nutricional. El pasto alpiste se ha utilizado en diversas fincas de ganado de leche y ha adquirido importancia como una opción que puede soportar las condiciones climatológicas de las regiones altas de Costa Rica; asimismo, ya hay empresas que importan semilla sexual de dicha especie.
