Resumo: The knowledge of ruminal degradation kinetics of forage cactus-based diets associated with Euphorbiaceae species of the genus Manihot assist in understanding nutrient quality and use, contributing to the indication of combinations of these ingredients in ruminant diets. This study aimed to evaluate the in situ ruminal degradability of diets with increasing association of forage cactus Elephant Ear (MEE) and pornunça (Manihot sp.) silage, as well as to analyze and evaluate the indigestible neutral detergent fiber (FDNi) content of forage cactus MEE and pornunça silage. The treatments consisted of diets with cactus pear associated with pornunça silage in the roughage portion in the proportions of 375, 250, 125 and 0 g kg-1 of DM. The feed was composed of 50% roughage and 50% concentrate of dry matter. Incubation times of 0, 6, 12, 24, 48, 96, and 144 hours were evaluated for the ingredients and 0, 2, 4, 6, 8, 12, 24, 48, 72, and 96 hours for the diets. Incubation to obtain the iNDF was given for 288 hours. The experimental design consisted of randomized blocks, with three replications. Regarding roughage ingredients, MEE showed higher average disappearance, potential degradability (PD), and effective degradability (ED) in relation to pornunça silage, as well as lower NDFi content. The proportion of 375 g kg-1 MEE and 125 g kg-1 pornunça silage provided higher fractions a, b, and c, increasing ED considering the three passage rates, with higher PD. In conclusion, the association between MEE and pornunça silage at a proportion of 375 g kg-1 MEE and125g kg-1 pornunça silage of the roughage portion increases the in situ degradability of dry matter, crude protein, and neutral detergent fiber.

Objetivou-se avaliar a degradabilidade ruminal in situ de dietas com crescente associação de palma-forrageira Orelha de Elefante Mexicana (OEM) e silagem de pornunça (Manihot sp.), assim como, avaliar o teor de fibra em detergente neutro indigestível (FDNi) da palma OEM e da silagem de pornunça. Os tratamentos consistiram em dietas com palma forrageira associada à silagem de pornunça na porção volumosa nas proporções de 375, 250, 125 e 0 g kg-1 na MS. A dieta foi composta por 50% de volumoso e 50% de concentrado da matéria seca. Foram avaliados os tempos de incubação de 0, 6,12, 24, 48, 96 e 144 para os ingredientes e 0, 2, 4, 6, 8 ,12, 24, 48, 72 e 96 para as dietas. A incubação para a obtenção do FDNi foi realizada por 288 horas. O delineamento experimental utilizado foi em blocos casualizados, com três repetições. Quanto aos ingredientes volumosos, a palma OEM apresentou maior desaparecimento médio, degradabilidade potencial (DP) e degradabilidade efetiva (DE) em relação à silagem de pornunça, bem como menor teor de FDNi. A proporção de 375 g kg-1 OEM e 125 g kg-1 de silagem de pornunça propiciou maiores frações a, b e c, atuando no aumento da DE considerando as três taxas de passagem, com maior DP. Conclui-se que à associação de palma OEM e silagem de pornunça na proporção de 375 g kg-1 OEM e 125 g kg-1 da silagem de pornunça da porção volumosa aumenta a degradabilidade in situ da matéria seca, proteína bruta e fibra em detergente neutro.UEL2023-04-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4624310.5433/1679-0359.2023v44n2p549Semina: Ciências Agrárias; Vol. 44 No. 2 (2023); 549-566Semina: Ciências Agrárias; v. 44 n. 2 (2023); 549-5661679-03591676-546Xreponame:Semina.
