Introduction. Forages in the tropics have low digestibility, which is why alternative feed option such as Tithonia diversifolia (Hemsl.) are sought to improve the quality of the offered diet. Objective. To evaluate the effect of fertilizer type and the regrowth age of Tithonia diversifolia forage on rumimal parameters. Materials and methods. The study was conducted in 2020 at the Santa Lucía Experimental Farm of the Universidad Nacional, Costa Rica. A completely randomized split-plot design was used with fertilizer type as the main plot and regrowth age as subplot, with three replications per treatment. The fertilizer types were: vermicompost (L), chemical (Q), and control (C) without fertilizer use. The evaluated regrowth ages were 30, 50, and 70 days, resulting in a total of nine treatments. The variables assessed were: in situ dry matter degradability kinetics (DISMS), pH, ammoniacal nitrogen (NH3), in vitro gas, and methane production (CH4). An ANOVA was carried out for divided plots. Results.The highest DISMS was found in C30 (92.84 %) and the lowest in Q70 (64.21 %). The type of fertilization influenced NH3 contents, with the highest value observed in chemical fertilizer treatments (275.88 mg NH3/L rumen fluid). C70 produced the highest amount of gas (79.59 mL/g), whereas Q30 had the lowest average (28.38 mL/g). Methane production did not show significant differences, with values ranging from 3.42 to 8.67 mL CH4/g DM. Conclusion. Fertilization and regrowth age modified in situ and in vitro ruminal parameters. The obtained results suggest that this forage resource can be considered a supplement to grazing grasses in the tropics, where positive effects are generated on DM digestibility, gas, and CH4 production. |

Los forrajes en el trópico presentan una baja digestibilidad, por lo que se buscan alternativas alimenticias como la Tithonia diversifolia (Hemsl.) para aumentar la calidad de la dieta ofrecida. Objetivo. Evaluar el efecto del tipo de fertilizante y la edad de rebrote del forraje de Tithonia diversifolia sobre los parámetros ruminales. Materiales y métodos. El trabajo se realizó en el año 2020 en la Finca Experimental Santa Lucía de la Universidad Nacional, Costa Rica. Se utilizó un diseño de parcelas divididas completamente al azar con el tipo de fertilizante como parcela principal y edad de rebrote como subparcela, con tres repeticiones por tratamiento. Los tipos de fertilizante fueron: lombricompost (L), químico (Q) y control (C) sin fertilizante. Las edades de rebrote evaluadas fueron 30, 50 y 70 días para un total de nueve tratamientos. Las variables evaluadas fueron: cinética de degradabilidad in situ de la materia seca (DISMS), pH, nitrógeno amoniacal (NH3), producción de gas y metano in vitro (CH4). Se realizó un ANDEVA para parcelas divididas. Resultados. La mayor DISMS se encontró en C30 (92,84 %) y menor en Q70 (64,21 %). El tipo de fertilización influyó sobre los contenidos de NH3, el mayor valor se presentó en los tratamientos con fertilización química (275,88 mg NH3/L fluido ruminal). C70 produjo la mayor cantidad de gas (79,59 mL/g), en contraste con Q30 que fue el de menor promedio (28,38 mL/g). La producción de CH4 no mostró diferencias significativas, con valores entre 3,42 y 8,67 mL CH4/g MS. Conclusión. La fertilización y edad de rebrote modificaron los parámetros ruminales in situ e in vitro. Los resultados obtenidos permiten considerar este recurso forrajero como un complemento de las gramíneas de pastoreo en el trópico, donde se generen efectos positivos sobre la digestibilidad de la MS, la producción de gas y de CH4.Universidad de Costa Rica2023-07-11info:eu-repo/semantics/publishedVersionArticleTextTextoartículo originalhttp://purl.org/coar/resource_type/c_18cfhttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articletext/xmlapplication/pdfapplication/epub+ziptext/htmlaudio/mpegaudio/mpeghttps://revistas.ucr.ac.cr/index.php/agromeso/article/view/5319210.15517/am.2023.53192Agronomía Mesoamericana; 2023: Agronomia Mesoamericana: Vol. 34, Issue 3 (September-December) ; 53192 Agronomía Mesoamericana; 2023: Agronomía Mesoamericana: Vol. 34, Nº 3 (septiembre-diciembre) ; 53192Agronomía Mesoamericana; 2023: Agronomía Mesoamericana: Vol. 34, Nº 3 (septiembre-diciembre) ; 531922215-36081021-7444reponame:Portal de Revistas UCRinstname:Universidad de Costa Ricainstacron:UCRspaenghttps://revistas.ucr.ac.cr/index.php/agromeso/article/view/53192/56885https://revistas.ucr.ac.cr/index.php/agromeso/article/view/53192/56455https://revistas.ucr.ac.cr/index.php/agromeso/article/view/53192/56886https://revistas.ucr.ac.cr/index.php/agromeso/article/view/53192/56887https://revistas.ucr.ac.cr/index.php/agromeso/article/view/53192/56888https://revistas.ucr.ac.cr/index.php/agromeso/article/view/53192/56889Derechos de autor 2023 Luis Mauricio Arias-Gamboa, Michael López-Herrera, Miguel Castillo-Umaña, Andrés Alpízar-Naranjohttps://creativecommons.org/licenses/by-nc-nd/4.0acceso abiertohttp://purl.org/coar/access_right/c_abf2info:eu-repo/semantics/openAccess2023-12-13T20:00:02Zoai:portal.ucr.ac.cr:article/53192Portal 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:2025-08-13T10:30:06.399Portal de Revistas UCR - Universidad de Costa Ricafalse |
