An assessment of the ability of the stay-green phenotype in Lolium species to provide an improved protein supply for ruminants

Humphreys, Mervyn O.; Kingston-Smith, Alison H.; Theodorou, Michael K.; Bollard, Andrea L. (2002-06-01)

The stay-green phenotype results from a naturally occurring mutation in which senescent leaves retain their chlorophyll and the associated apoprotein, LHCPII. Protection of this protein pool could deliver grass with enhanced ...

This book contains a compilation of offered papers presented at the main congress of the XX International Grassland Congress held in University College Dublin, Ireland from 26 June to 1 July, 2005. It is complemented by ...

Detection and monitoring of anaerobic rumen fungi using an ARISA method

McSweeney, Christopher S.; Nicholson, Matthew J.; Theodorou, Michael K.; Brookman, Jayne L.; Denman, Stuart E. (2008-12-01)

Aim: To develop an automated ribosomal intergenic spacer region analysis (ARISA) method for the detection of anaerobic rumen fungi and also to demonstrate utility of the technique to monitor colonization and persistence ...

Diversity and activity of enriched ruminal cultures of anaerobic fungi and methanogens grown together on lignocellulose in consecutive batch culture

Cheng, Yan Fen; Edwards, Joan E.; Allison, Gordon G.; Zhu, Wei-Yun; Theodorou, Michael K. (2009-10)

Consecutive batch cultures (CBC), involving nine serial transfers at 3, 5 and 7 d intervals (21, 45 and 63 d, respectively) were established to enrich for plant fibre degrading co-cultures of anaerobic fungi and methanogens ...

Diversity and host bias of anaerobic gut fungal populations analysed using ribosomal ITS1 sequences in faeces of wild and domesticated herbivores

Nicholson, Matthew J.; McSweeney, Christopher S.; Mackie, Roderick I.; Theodorou, Michael K.; Brookman, Jayne L. (2010-04-01)

Gut fungal-specific PCR primers have been used to selectively amplify the ITS1 region of gut fungal rDNA recovered from faeces of domestic and wild animals to investigate population diversity. Two different gel-based methods ...

Effect of condensed tannins from tropical legumes on the activity of fibrolytic enzymes from the rumen fungus Neocallimastyx hurleyensis

Sanchez, S.; Lascano, Carlos E.; Owen, E.; Barahona, Rolando; Morris, Phillip; Theodorou, Michael K. (2006-06-26)

study was conducted to assess the effect of condensed tannins on the activity of fibrolytic enzymes from the anaerobic rumen fungus, Neocallimastix hurleyensis and a recombinant ferulic acid esterase (FAE) from the aerobic ...

The effect of sample processing on gas production profiles obtained using the pressure transducer technique

Cuddeford, Derek; Lowman, Rebecca S.; Theodorou, Michael K. (2002-03-13)

This research considers the effects of feedstuff processing (drying, fractionation and particle size) on the resultant fermentation characteristics of the feed. The effect of drying was investigated using fresh perennial ...

Effects of manipulating the protein content of white clover on silage quality

Winters, Ana L.; Minchin, Frank R.; Davies, Zoe; Kingston-Smith, Alison H.; Theodorou, Michael K.; Griffith, Gareth W.; Merry, Roger J. (2004-10-15)

White clover nitrogen N content is generally high and constant throughout the growing season. It is also difficult to manipulate, as N2 fixation tends to maintain a high N supply to the plant. White clover is a highly ...

Evidence in support of a role for plant-mediated proteolysis in the rumens of grazing animals

Merry, Roger J.; Leemans, David K.; Kingston-Smith, Alison H.; Theodorou, Michael K.; Thomas, Howard (2005-02-12)

The present work aimed to differentiate between proteolytic activities of plants and micro-organisms during the incubation of grass in cattle rumens. Freshly cut ryegrass was placed in bags of varying permeability and ...

Grass cells ingested by ruminants undergo autolysis which differs from senescence: implications for grass breeding targets and livestock production

Beha, Elke M.; Thomas, Barry J.; Theodorou, Michael K.; Kingston-Smith, Alison H. (2002-09-19)

It is widely believed that the initial degradation of proteins contained in grazed forage is mediated by rumen micro-organisms, but the authors' recent work suggests that the plant cells themselves contribute to their own ...

In vitro degradability of mature and immature leaves of tropical forage legumes differing in condensed tannin and non-starch polysaccharide content and composition

Barahona, Rolando; Lascano, Carlos E.; Theodorou, Michael K.; Morris, Phillip; Narvaez, Nelmy; Owen, Emir (2003-08-08)

A study was designed to examine the relationships between protein, condensed tannin and cell wall carbohydrate content and composition and the nutritional quality of seven tropical legumes (Desmodium ovalifolium, Flemingia ...

Theodorou, Michael K.; Brookman, Jayne L.; Nicholson, Matthew J. (2005-01-06)
