Contribution of gut microbial lysine to liver and milk amino acids in lactating does
Abecia, Leticia; Balcells Terés, Joaquim; Fondevila, Manuel; Belenguer, Álvaro; Holtrop, G.; Lobley, Gerald E. (Cambridge University Press, 2008)The contribution of microbial amino acids through caecotrophy to tissue protein metabolism was investigated in lactating does. Attempts were made to vary microbial supply through a dietary antibiotic, Zn bacitracin, and ... -
Effect of carbohydrate source on microbial nitrogen recycling in growing rabbits
Balcells Terés, Joaquim; Belenguer, Álvaro; Abecia, Leticia; Belanche, Alejandro; Milne, Eric (Elsevier, 2012)In rabbits, caecal fermentation relies to a large extent on the type of substrate available for bacteria. Therefore, in order to study the dietary effect of the source of carbohydrate on microbial nitrogen (N) absorption, ... -
Effect of slurry dilution, structural carbohydrates, and exogenous archaea supply on in vitro anaerobe fermentation and methanogens population of swine slurry
Morazán Nuñez, Henris Jobany; Seradj, Ahmad Reza; Álvarez Rodríguez, Javier; Abecia, Leticia; Babot Gaspa, Daniel; Yañez-Ruiz, David R.; Balcells Terés, Joaquim (American Institute of Chemical Engineers (AIChE), 2015-01)Artificial slurry (4% dry matter) was prepared using fresh feces and urine obtained from four pregnant sows fed with commercial diet. Freeze-dried dairy cattle feces were used (external archaea) as co-inoculum (Co-i) and ... -
Estudio de la evolución de las poblaciones metanógenas en la digestión anaerobia del purín y su relación con el aporte exógeno de carbohidratos estructurales o arqueas exógenas
Seradj, Ahmad Reza; Morazán Nuñez, Henris Jobany; Álvarez Rodríguez, Javier; Abecia, Leticia; Babot Gaspa, Daniel; Yañez-Ruiz, David R.; Balcells Terés, Joaquim (Asociación Interprofesional para el Desarrollo Agrario, 2013)Three agricultural by products (CHO:wheat straw, apple pulp and sugar beet pulp) as substrate plus 2 levels of freeze-dried cow’s feces (C0-i: 5 and 10 %) as co-inoculum were assigned in quadruplicate during 56 days of in ... -
Rumen protozoal diversity in the Spanish ibex (Capra pyrenaica hispanica) as compared with domestic goats (Capra hircus)
de la Fuente Oliver, Gabriel; Belanche, A.; Abecia, Leticia; Dehority, Burk A.; Fondevila, Manuel (Elsevier, 2008-10-16)Rumen protozoal diversity in the Spanish ibex (SI) was studied in males (n=4), females (n=7) and young (n=4) from the Maestrazgo (Spain) and contrasted with domestic goats (n=3; DG) of the same region. There were no ... -
Study of the effect of presence or absence of protozoa on rumen fermentation and microbial protein contribution to the chyme
Belanche, A.; Abecia, Leticia; Holtrop, G.; Guada, J. A.; Castrillo, C.; de la Fuente Oliver, Gabriel; Balcells Terés, Joaquim (American Society of Animal Science, 2011-06-29)The aim of this study was to investigate the effect of presence or absence of protozoa on rumen fermentation and efficiency of microbial protein synthesis under different diets. Of 20 twin paired lambs, 1 lamb of each pair ... -
The effect of Bioflavex® and its pure flavonoid components on in vitro fermentation parameters and methane production in rumen fluid from steers given high concentrate diets
Seradj, Ahmad Reza; Abecia, Leticia; Crespo, J.; Villalba Mata, Daniel; Fondevila, Manuel; Balcells Terés, Joaquim (Elsevier, 2014-11)An in vitro assay was designed to analyze the effect of either Bioflavex (R) (BF) or each of its pure flavonoid components [Neoeriocitrine (NE), Naringine (NG), Isonaringine (IN), Hesperidine (HS), Neohesperidine (NH), ... -
Validation of sheep rumen fluid frozen in liquid N as inoculum for in vitro gas production trials.
Prates, A.; de Oliveira, J.A.; de la Fuente Oliver, Gabriel; Abecia, Leticia; Fondevila, Manuel (Centre international de hautes études agronomiques méditerranéennes, 2011)The effect of freezing rumen fluid in liquid nitrogen for its use as inoculum for in vitro incubation was evaluated in a semi-continuous system. Inoculum was used immediately (RF) or frozen and then thawed and used (TW) ...
