  • "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."
