“…However, Molano et al (2008) observed a decrease in DM intake when supplementing lambs with free fumaric acid at 80 and 100 g/kg DM. These results suggest that encapsulation may be a useful procedure for administering high doses of organic acids to ruminants avoiding negative effects on feed intake (Carro and Ungerfeld, 2015).…”

“…Organic acids are frequently used as antimicrobial additives in non-ruminant animals feeding to change the composition of gut microbiota. In ruminants, most research has focused on malate and fumarate, both of which are intermediates in the tricarboxylic acid cycle and in the randomizing pathway of propionate production in the rumen (Carro and Ungerfeld, 2015).…”

“…Supplying malate and fumarate, or their sodium salts, to semi-continuous flow (Rusitec) fermenters resulted in decreased lactate concentrations and increased ruminal pH (Carro et al, 1999;Lopez et al, 1999;Carro and Ranilla, 2003). Some studies (reviewed by Carro and Ungerfeld, 2015) have also reported a decrease in methane production as a consequence of malate and fumarate supplementation, which can result in higher fermentation efficiency and reduced environmental impact due to the greenhouse effect of methane.…”

“…2009), and salts have the advantages of being non-abrasive and safer to manipulate, although they are usually more expensive (Carro and Ungerfeld, 2015). An in vitro study performed by Martin and Streeter (1995) showed that the effect of free malic acid in the rumen was similar to that of disodium malate, although differences in chemical structure might imply different effects on ruminal fermentation.…”

“…Recently, Vyas et al (2015) administered fumaric acid to finishing crossbred heifers at low (61 g/d) or high (125 g/d) dosage and observed no effects on DM intake, ruminal pH, or total VFA concentrations and individual VFA profile. Inconsistences in the response to malate and fumarate supplementation may be explained by variations in the dose and form (free acid vs. salts), growth rate and age of the animal, diet composition, and farming conditions, among other factors (Carro and Ungerfeld, 2015). …”

2017 I II IV AgradecimientosLlegar hasta este momento de finalización de la Tesis Doctoral ha sido una carrera de fondo que me ha acompañado a lo largo de mi maduración tanto a nivel profesional como personal, acompañándome en la mochila en numerosos momentos clave de mi vida.Todo empezó nada más presentar mi proyecto fin de carrera, cuando Carlos de Blas, (que de manera sutil, o quizá involuntaria, ha tenido la capacidad de llevarme a lo que soy ahora) comentó "dos artículos más y ya tienes la Tesis". Si bien en aquel momento me pareció una idea imposible, en el fondo se quedó plantada una semilla que comenzó a germinar el día en el que Pedro Medel me encargó realizar el estado del arte del proyecto de investigación que, con el soporte de COPESE, ha dado lugar a este trabajo.Recuerdo perfectamente aquel primer momento en el que visitamos la granja de terneras por primera vez y Javier Peinado dejó en mis manos el control de los ensayos.Llegar hasta el final de este proyecto hubiera sido imposible sin el apoyo tanto de mis compañeros de Imasde en aquellos momentos (Álvaro, Silvia, Jaime, Nacho y Fran), como de David del Pico, Marcos Nieto y Alfonso Fuentetaja de COPESE y, por supuesto, los profesores, investigadores y doctorandas del Departamento de Producción Animal I de la Universidad de León (Loli, Mariajo, Marisa, Eugenia, Silvia, Alfonso..) por su apoyo tanto en granja como en matadero, y especialmente en laboratorio.Quedan atrás muchos días de frío, me atrevería a decir casi siberiano, donde antes de empezar los ensayos algún día nos encontramos a Javier Rincón descongelando tuberías a soplete; aquellos momentos en los que una ternera despistada nos hacía correr los San Fermines por los pasillos, o los madrugones para poder realizar los controles en matadero. Son muchas las anécdotas que quedan atrás, y guardo con buen sabor de boca, un poco de nostalgia, pero especialmente satisfacción por todo lo vivido y aprendido, junto con el sincero agradecimiento a todos los que me han acompañado en este camino. En este proceso de aprendizaje, cabe sin duda la mención especial a mis directores, Pedro y Loli que, sin prisa pero sin pausa, me han impulsado a finalizar este trabajo.Los trabajos realizados en el marco de esta Tesis Doctoral han sido promovidos por Comercial Pecuaria Segoviana, SL (Coca, Segovia, Spain), y llevados a cabo en su granja experimental de terneros de cebo. Este proyecto ha sido financiado por el Ministerio de Industria Turismo y Comercio mediante el programa PROFIT (FIT060000200511) y el Centro para el Desarrollo Tecnológico Industrial (CDTI; IDI-20050617 RESUMENEl objetivo de esta Tesis ha sido estudiar la influencia de diferentes estrategias nutricionales sobre el control de la acidosis en terneros de cebo en un contexto experimental diseñado para representar el manejo nutricional predominante en España. Para ello, se llevaron a cabo tres ensayos experimentales que se describen a continuación.El primer experimento se diseñó para evaluar el efecto de la inclusión de malato, administra...

This study investigated silage quality characteristics and ruminal fiber degradability of grass and straw ensiled with either anaerobic fungi (AF) supernatant with active fungal enzymes or mixed ruminal fluid as novel silage additives. Compared to control silages, AF supernatant improved the quality of grass and straw silages as evidenced by decreased pH, acetic acid concentration, and dry matter losses. Likewise, mixed ruminal fluid enhanced lactic acid fermentation, which further resulted in lower pH of the treated grass silage. The ruminal fiber degradability was determined using in situ incubations and, compared to controls, the cellulose degradability was higher for grass silage with AF supernatant, whereas ruminal degradability of straw silage was reduced by this treatment. In contrast, mixed ruminal fluid did not influence fiber degradability of silages in the rumen. Concluding, both novel additives improved silage quality, whereas only AF supernatant enhanced ruminal fiber degradability of grass silage and therefore may represent an approach for improving forage utilization by ruminants. Key points • Enzymes of anaerobic fungi supernatant improve quality of grass and straw silages. • Mixed ruminal fluid enhances lactic acid fermentation when ensiling grass and straw. • Enzymes of anaerobic fungi supernatant increase ruminal grass silage degradability.
