description Introduction. Tropical pastures have higher fiber content in proportion to other nutrients, this limits the dry matter intake by ruminants. Usage of additives in silage can improve nutritive content in forages that can be preserved to use in moments of lower forage availability. Objective. The objective of this research was to evaluate the effect of substituting Megathyrsus maximus cv Mombaza grass for immature square bananas (Musa ABB) and urea in silages. Materials and methods. The experiment was carried out between August and December 2016. A factorial design with eight treatments was used. The forage mixtures were stored for sixty days in bags of 5.0 kg bags. Results. Usage of square banana fruit produced an increase in pH, ammonia nitrogen, and urea. The fruit also increased the concentration of dry matter and non-fibrous carbohydrates, this improved the relative value of the forage and the energy content. On the other hand, urea improved the crude protein content by 10 percentage units, due to its contribution as non-proteic nitrogen. The energy content of the treatments fluctuated between 59.5 and 63.6% TND, in the treatments with greater use of square banana fruit. Conclusion. Silage with 30% of substitution by square banana fruit and 0.5 - 1.0% urea are considered an alternative for feeding ruminants, as a complement to a balanced diet.

Los pastos tropicales poseen mayor contenido de fibra en proporción con otros nutrientes, esto limita el consumo de materia seca por parte de los rumiantes. El uso de aditivos en el ensilaje permite optimizar el contenido nutricional en los forrajes que pueden conservarse para utilizarlos en momentos de menor disponibilidad forrajera. Objetivo. El objetivo de esta investigación fue evaluar el efecto de sustituir en ensilados, porcentajes de pasto Megathyrsus maximus cv Mombaza por fruto inmaduro de guineo cuadrado (Musa ABB) y urea. Materiales y métodos. El experimento se desarrolló entre agosto y diciembre de 2016. Se utilizó un diseño factorial con ocho tratamientos. Las mezclas se almacenaron durante sesenta días en bolsas de 5,0 kg. Resultados. El uso de fruto de guineo cuadrado produjo incremento del pH, el nitrógeno amoniacal, y la urea. El fruto también aumentó la concentración de materia seca y carbohidratos no fibrosos, esto mejoró el valor relativo del forraje y el contenido de energía. La urea mejoró en diez unidades porcentuales el contenido de proteína cruda, debido a su aporte de nitrógeno no proteico. El contenido de energía de los tratamientos varió entre 59,5 y 63,6%TND, y la mayor energía se obtuvo en los tratamientos con mayor uso de fruto de guineo cuadrado. Conclusión. Los ensilados con 30% de sustitución con fruto de guineo cuadrado y 0,5 - 1,0% de urea, se pueden considerar una alternativa para alimentación de rumiantes, como complemento de una dieta balanceada.Universidad de Costa Rica2019-01-01info:eu-repo/semantics/publishedVersionArticleartículo originalhttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articleapplication/pdftext/htmlapplication/ziptext/xmlhttps://revistas.ucr.ac.cr/index.php/agromeso/article/view/3247810.15517/am.v30i1.32478Agronomía Mesoamericana; 2019: Agronomía Mesoamericana: Vol. 30, Issue 1 (January-April); 179-194 Agronomía Mesoamericana; 2019: Agronomía Mesoamericana: Vol. 30, Nº 1 (Enero-abril); 179-194Agronomía Mesoamericana; 2019: Agronomía Mesoamericana: Vol. 30, Nº 1 (Enero-abril); 179-1942215-36081021-7444reponame:Portal de Revistas UCRinstname:Universidad de Costa Ricainstacron:UCRspahttps://revistas.ucr.ac.cr/index.php/agromeso/article/view/32478/36547https://revistas.ucr.ac.cr/index.php/agromeso/article/view/32478/36548https://revistas.ucr.ac.cr/index.php/agromeso/article/view/32478/36709https://revistas.ucr.ac.cr/index.php/agromeso/article/view/32478/37006acceso abiertohttp://purl.org/coar/access_right/c_abf2info:eu-repo/semantics/openAccess2023-06-16T13:46:54Zoai:portal.ucr.ac.cr:article/32478Portal de revistashttps://revistas.ucr.ac.cr/Universidadhttp://www.ucr.ac.crhttps://revistas.ucr.ac.cr/index.php/index/oaijorge.polanco@ucr.ac.crCosta RicaNo aplicaNo aplicaNo aplicaopendoar:2025-08-13T10:29:33.325Portal de Revistas UCR - Universidad de Costa Ricafalse
