Citation of this paper. No obstdante que el pasto kikuyo Pennisetum clandestinum Hoechst Ex Chiov. Pennisetum clandestinum Hoechst Ex Chiov , is the most utilized forage in dairy cattle specialized herds in the Colombian Andes. However, it has nutritional limitations the most important being a low energy content affecting both yield and composition o milk of cows grazing this forage.

The high concentration of neutral detergent fiber NDF , low dry matter and non-structural carbohydrates concentration does not seem to limit the dry matter intake DMI of animals grazing this forage. DMI higher than The mean potential for milk production of cows grazing kikuyu grass is nearly Feed supplementation improves milk yield without improving its lipid and protein content.

The low milk protein content less than 3. Key words: Fatty acids, linoleic, linolenic, nitrogen, protein. Aunque el pasto kikuyo Pennisetum clandestinum Hoechst. Ex Chiov. Tabla 1. Al evaluar el contenido de EM en los tallos, este valor se redujo a 1. Tabla 2. Consumo de materia seca y de FDN de pasto kikuyo encontrado en Antioquia 1. Figura 1. El CMS fue calculado por la diferencia entre el forraje ofrecido de manera individual y el rechazo cada 24 horas, Los datos mostrados en la figura 1 corresponden al CMS del pasto kikuyo.

Figura 2. En el departamento de Cundinamarca se han estimado consumos mayores Este es un rango muy similar al propuesto por Leaver Sierra y Zabala hallaron que el contenido de MS del pasto kikuyo oscila entre Estos autores estudiaron el comportamiento en pastoreo de vacas holstein lactantes en un hato lechero de Antioquia y encontraron que el porcentaje de animales pastoreando fue alto entre las y p.

Un ritmo de pastoreo similar es descrito por Van Soest en ovejas durante los meses de verano. El contenido promedio de ENl del pasto kikuyo, por otro lado, es 1.

Tabla 3. Tabla 4. Tabla 5. Sin embargo, al igual que en dicho caso, tampoco hubo efecto de los tratamientos sobre las variables evaluadas indicando que la deficiencia en CNE del pasto kikuyo no es factible de corregir con este tipo de suplementos alimenticios o que la cantidad que es necesario suministrar es mayor a la que normalmente se utiliza. Figura 3. Figura 4. Rico et al , por su parte, reportaron un promedio de 3.

El promedio de los datos analizados, sin embargo, es de Figura 5. La digestibilidad de la PNDR del pasto kikuyo y de los suplementos alimenticios suministrados a las vacas experimentales se estimaron a partir de los datos obtenidos por Caro y Correa y por Monsalve Tabla 6.
