Effects of including a ruminally protected lipid supplement in the diet on the fatty acid composition of beef muscle

Scollan, Nigel D.; Enser, Mike; Gulati, Suresh; Richardson, R. Ian; Wood, Jeff D. (2003-09-18)

Enhancing the polyunsaturated fatty acid (PUFA) and decreasing the saturated fatty acid content of beef is an important target in terms of improving the nutritional value of this food for the consumer. The present study ...

Sanderson, Ruth; Davies, David R.; Bakewell, Eleanor L. (2007)
Effects of inclusion of whole-crop pea silages differing in their tannin content on the performance of dairy cows fed high or low protein concentrates

Sinclair, L. A.; Hart, K. J.; Wilkinson, R. G.; Huntington, J. A. (2009-09)

The effect of including high or low tannin forage peas as an alternative to soyabean meal on performance and N efficiency was investigated using 18 dairy cows in two Latin square design studies. Two varieties of forage ...
Effects of incorporating lupins compared with soya bean meal into concentrate diets on nitrogen and phosphorus partitioning and utilisation in dairy cows

Marley, Christina; Fychan, Rhun; Gordon, Naomi; Leyland, Martin; Theobald, Vince; Sanderson, Ruth; Abberton, Michael; Theobald, Vincent John (International Lupin Association, 2011)
Effects of incorporating yellow lupins into concentrate diets compared with soya on milk production and milk composition when offered to dairy cows

Marley, Christina L.; Davies, David R.; Fisher, William J.; Fychan, Rhun; Sanderson, Ruth; Jones, Raymond; Abberton, Michael T. (2008)

An experiment investigated the hypothesis that incorporating lupins (Lupinus spp.) compared with soya bean (Glycine max) meal into concentrate diets would not alter the yield or composition of milk from dairy cows. There ...
The effects of incremental fish oil supplementation on bacterial populations in the rumen

Huws, S. A.; Kim, E. J.; lee, M. R. F.; Pinloche, E.; Wallace, R. I.; Scollan, N. D. (Wageningen Academic Publishers, 2009)

This book contains the proceedings of the XIth International Symposium on Ruminant Physiology. The papers address ruminant comparative physiology, the rumen ecosystem and metagenomics, nutrient digestion and absorption, ...
Effects of index selection and sire breed on crossbred lamb growth and finishing

Marquez, G. C.; Haresign, W.; Davies, M. H.; Roehe, R.; Bunger, L.; Simm, G.; Lewis, R. M. (2010)
Effects of inhibiting phenolic biosynthesis on penetration resistance of barley isolines containing seven powdery mildew resistance genes or alleles

Kruger, W. M.; Carver, Timothy L. W.; Zeyen, R. J. (2002-07)

Barley leaf epidermal cells actively resist penetration by germinated conidia of the powdery mildew fungus Blumeria graminis f. sp. hordei (Bgh). Penetration resistance to the appropriateforma specialis (f. sp.) of Bg is ...
Effects of inoculation of ryegrass at ensiling on production of milk from dairy cows and whole body N partitioning

Moorby, Jon M.; Davies, David R.; Fisher, William J.; Ellis, Naomi Mary (2007)
Effects of lambing date on the birth weight of lambs from either cross-bred ewes carrying a prolificacy gene or a control.

Marley, Christina Louise; Jones, Hefin Geraint; Evans, Tom; Sanderson, Ruth; Theobald, Vince (British Grassland Society, 2013-09-02)
Effects of legume forages on ovine gastrointestinal parasite development, migration and survival.

Marley, Christina L.; Fraser, Mariecia D.; Roberts, John E.; Fychan, A. Rhun; Jones, Raymond (2006-06-15)

Lambs grazing certain legumes have reduced parasite intensities compared to lambs grazing ryegrass swards. Eighteen replicates of white clover (cv. AberHerald), lucerne (cv. Luzelle), red clover (cv. Merviot) and perennial ...
Effects of legume genetic diversity on the productivity of legume/grass mixtures - COST Action 852

Collins, Rosemary P.; Connolly, J.; Porqueddu, C. (EGF, 2004)

EGF is a forum for research workers, advisors, teachers, farmers and policy makers with active interest in all aspects of grasslands in Europe. These aspects include management of all types of grasslands for production, ...
Effects of legume silages on diet digestibility and rumen function

Tuori, M.; Merry, Roger J.; Dewhurst, Richard J. (2002)
Effects of legume silages on the concentration of alpha-linolenic acid in milk

Davies, D. W. Robert; Tweed, John K. S.; Dewhurst, Richard J.; Fisher, William J. (2002)
Effects of level of concentrate feeding during the second gestation of Holstein-Friesian dairy cows. 1. Feed intake and milk production.

Dewhurst, Richard J.; Moorby, Jon M.; Dhanoa, M. S.; Fisher, William J. (2002-01)

The objective of this experiment was to examine the residual effects of the level of concentrate feeding during the second gestation on performance in the second lactation. Forty-three Holstein-Friesian heifers that calved ...
Effects of level of concentrate feeding during the second gestation of Holstein-Friesian dairy cows. 2. Nitrogen balance and plasma metabolites

Moorby, Jon M.; Dewhurst, Richard J.; Evans, Richard T.; Fisher, William J. (2002-01)

We offered 43 Holstein-Freisian dairy heifers that calved for the first time at either 2 or 3 yr of age ad libitum access to ryegrass silage and a standard concentrate allowance of either 2 or 7 kg/d from the middle to the ...
The effects of livestock grazing on foliar arthropods associated with bird diet in upland grasslands of Scotland

Dennis, Peter; Skartveit, John; McCracken, David I.; Pakeman, Robin J.; Beaton, Katy; Kunaver, Anja; Evans, Darren M. (2008-02-01)

1. Upland biotopes have conservation importance for their typical plant and animal species. Recently, the condition of upland habitats has deteriorated with associated declines in many upland birds. Grazing by increased ...
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 ...
Effects of metal (Cd, Cu, Ni, Pb or Zn) enrichment of sewage-sludge on soil micro-organisms and their activities

Khan, M.; Scullion, John (2002-05)

Sewage-sludge may improve soil fertility but there is concern about effects of sludge metals on soil micro-organisms and microbial processes. In a series of laboratory incubations of soil–sludge mixes, effects of varying ...
Effects of mixtures of red clover and maize silages on the partitioning of dietary nitrogen between milk and urine by dairy cows

Dewhurst, Richard J.; Kim, Eun J.; Davies, L. J. (2010-01-07)
