La baja productividad animal (carne, lana y leche) durante la época seca los productores buscan alternativas para mejorar esta deficiencia con la instalación de pastos permanentes y anuales, los cuales dispone de mejores rendimientos de forraje y calidad nutritiva. El objetivo del estudio fue de determinar el rendimiento forrajero y valor nutritivo de dos variedades de Avena sativa (Criolla y Mantaro-15) en la sierra central del Perú. El estudio se condujo en las regiones de Pasco y Junín, cuyo objetivo fue determinar el rendimiento forrajero y valor nutritivo de dos variedades de avena sativa en la sierra central del Perú. Para ello, se estudiaron los rendimientos forrajeros (MV, MS y %MS) y se analizaron el valor nutritivo (%PT, %FDN, %FDA, %DIVMO, %Ca, %P y EM) de las avenas. Para el análisis estadístico se utilizó el diseño de bloques completamente al azar. Los resultados de rendimiento forrajero para la avena Criolla en MV (14 456.0 kg ha-1), MS (2 423.4 kg ha-1) y %MS (16.8), en la avena Mantaro-15 en MV (21 067.0 kg ha-1) y MS (3 215.0 kg ha-1) y %MS (15.5). El valor nutritivo para la avena Criolla y Mantaro-15 en %PT (7.10 y 6.80), %FDN (42.90 y 34.80), %FDA (19.90 y 16.10), %DIVMO (87.80 y 78.90), %Ca (0.21 y 0.20), %P (0.24 y 0.21) y EM (14.00 y 12.60) respectivamente. Se concluye que la avena Mantaro-15 tiene mejores rendimientos forrajeros y una mejor calidad de fibra y en ambos casos cubren los requerimientos de los ovinos mostrando un balance positivo.
The study was carried out in the central highlands of Peru at 3,900 meters above sea level, in the Casaracra experimental center of the Daniel Alcides Carrión National University, where the objective was to determine and analyze the forage yield and nutritional quality of the associated grasses in different density is sowing. In forage production, the values of green matter and dry matter and the percentage of dry matter were determined; in nutritional quality, the nutritional variables% PT, %NDF, %FDA, % Ca and% P were analyzed. a completely randomized design was used. The results for forage yield for treatment 1 in MV was 3.54 kg / m2 and DM 0.68 kg / m2, in treatment 2 in MV it was 2.61 kg / m2 and DM 0.72 kg / m2, for treatment 3 in MV it was 3.07 kg / m2 and DM 0.98 kg / m2 and finally in treatment 4 the MV was 2.48 kg / m2 and DM 0.93 kg / m2. The nutritional quality for treatments 1, 2, 3 and 4 in% PT (15.56, 15.21, 6.81 and 5.37), % FDN (48.85, 43.82, 43.34 and 41.89), % FDA (28.82, 26.31, 27.27 and 24.43), % Ca (0.86, 0.80, 0.33 and 0.17), %P (0.25, 0.24, 0.18 and 0.07) respectively. Where it is concluded that treatment 4 showed acceptable fiber content in sheep feeding.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
