Digestibilidad aparente en llamas (Lama glama) alimentadas con (Stipa ichu) tratada con úrea y melaza en el C.E.A.C.
Abstract
The following work was conducted at the Agricultural Experimental Center under the title of : Apparent digestibility in llamas feed with stipa ichu (Peruvian feather grass) treated with urea and molasses, for which 3 assays were performed in reference to the study : 1) percentage of assimilation of the treated and non- treated grass, 2) apparent digestibility of fiber and protein after and before feeding, and 3) determine the adequate levels of urea and molasses for the chemical treatment of the grass (Stipa ichu). For the first assay, the greater consumption was obtained at the level of 3 (3% of urea) reporting a consumption index of 1895.67 gr, the least amount of consumption was found to be 0(0% of urea) reporting a consumption index of 1450.93 gr. The administered food prepared with (grass + urea + molasses) at the different levels of 3%, 2%, and 4%, we had a variability coefficient of 12.56%. The highest index of water consumption was obtain with the 0% untreated grass with a volume of 882.12 ml, and the least was found at level 2 (2%) with a volume of 335.71 ml, with an average of 424.27 ml/day with a variability coefficient of 77.02%. The amount of excreted feces were found to be produced in a greater amount when fed with grass with at 3 (3%) type of treatment with a total of 1059.8 gr, and the least amount of excretions was shown when fed with treatment 4 (4%) with 60.8 gr, with an average of 826.51 gr/day with a variability of 22.35%. For the second assay, we found that the apparent digestibility of fiber at the 3 different levels of treatment , the greater percentage of fiber assimilated by the organism was with those that received food at level 3 (3%) with a 76.78%, and the least with a 0 (0%) in relationship to the other treatments. The greater percentage of protein was obtained at level 4 (4%) with 49.48%, decreasing the protein level 2%, 3%, and 0%, we can say that the difference is due to the different levels of urea found in the treatments. For the third assay, the most consumed was level 3 (3%) of urea with an average of 94.83%, the second one is level 2 (2%) with an average of 85.71%, followed by level 4(4%) with 74.59%. We concluded that 2.6% of urea is acceptable for the supplementation of stipa ichu (Bolivian feather grass) for the feeding of llamas.

El trabajo de Investigación se llevo a acabo en el Centro Experimental Agropecuario Condoriri (C.E.A.C.) intitulado: Digestibilidad aparente en llamas (Lama glama) con paja suave Stipa ichu tratada con urea y melaza el cual se realizo 3 ensayos en referencia al trabajo 1) el porcentaje de asimilación y aprovechamiento de la paja tratada y sin tratar en el animal 2) Determinar la digestibilidad aparente en fibra y proteína del alimento entes y después del consumo del alimento 3) Determinar el nivel adecuado de urea y melaza para el tratamiento químico de la paja (Stipa ichu) se detalla a continuación: 1) En el primer Ensayo se obtuvo el mayor consumo correspondiente al nivel 3(3% de urea) con un consumo de 1895,67 gr., el menor consumo se encontró con el nivel 0(0% de urea) con 1450.93 gr., el alimento suministrado preparado con (paja suave + urea + melaza) en los diferentes niveles 3%, 2%, y 4% se tiene un coeficiente de variación de 12.56% El mas alto consumo de agua se obtuvo con el 0% paja sin tratar con un volumen de 882.14 ml, y el menor valor se encuentra en el nivel 2(2%) con un volumen de 335.71 ml, con un promedio de 424,27 ml/dia y un coeficiente de variación de 77.02%. La cantidad de heces excretadas se encontró la mayor cantidad en el tratamiento 3(3%) con 1059.8 gr. y la menor cantidad excretada mostró el nivel 4(4%) con 610.18 gr. con un promedio de 826.51 gr./día con un coeficiente de variación 22.35%. 2) El segundo ensayo se hallo el a) porcentaje de digestibilidad aparente de la fibra de los diferentes niveles, el mayor porcentaje de fibra del alimento tratado y de la asimilación del animal en su organismo el nivel 3(3%) con 76.78% y el menor es el 0(0%) en relación a los otros tratamientos tuvieron un incremento del 2.22%. b) El mayor porcentaje de proteína se obtuvo en el nivel 4(4%) con 49.48%, bajando el nivel proteico 2%, 3% y 0%, el ultimo valor es de 29.46%, se puede decir que la diferencia significativa se encuentra por los diferentes niveles de urea aplicados a la paja suave (Stipa ichu). 3) El nivel mas consumido, aceptado es el nivel 3(3%) de urea con un promedio de 94.83% el segundo aceptable es el nivel 2(2%) con 85.71% seguido del nivel 4(4%) con 74.59% y como ultimo el nivel 0(0%) con 72.55% aquí claramente se muestra la diferencia de la aceptación del alimento tratado y la no tan aceptable que es sin tratar, realizando ejercicios con las ecuaciones polinomiales se llego a la conclusión que el 2.6% de urea es aceptable por los animales en la suplementación de Stipa ichu en los maltones.
