SUMMMARY
The cattle in the southeast region suffers through the year, variability in the amount and quality of forages; which negatively affects the productive and reproductive performance of the animals, in this situation, the digestibility was evaluated in addition to changes in the rumen microbial population of three products of palm oil: oil mesocarp (OM), without oil mesocarp (WOM) and palm kernel (endosperm more hulls, EMH) using an in vitro culture medium under a completely randomized design. Similar results were found in the chemical analysis of the ingredients, except for ether extract and crude protein, where the EMH achieved the highest values (p ≤ 0.05), also higher digestibility (p ≤ 0.05) and a greater concentration of total and cellulolytic bacteria in medium containing EMH was observed compared with the OM and the WOM. Based on the nutritional value and digestibility of the byproducts of palm, palm kernel or EMH has a high potential use in ruminant nutrition.
