The effect of sulphur and growth regulators on growth characteristics and grain yield of spring sown wheat

Hussain, Z.; Leitch, Malcolm H. (2007-01)

During the year 1999, two field experiments (Experiments 1 and 2) were conducted at the University of Wales Aberystwyth U.K., to investigate the effects of soil and foliar applied sulphur (S) in wheat, in terms of its ...
Effect of sward dry matter digestibility on methane production, ruminal fermentation, and microbial populations of zero-grazed beef cattle

Hart, K. J.; Martin, P. G.; Foley, P. A.; Kenny, D. A.; Boland, T. M. (2009-10)

Increasing the digestibility of pasture for grazing ruminants has been proposed as a low-cost practical means of reducing ruminant CH(4) emissions. At high feed intake levels, the proportion of energy lost as CH(4) decreases ...
The effect of sward surface height on the response to mixed grazing by cattle and sheep

Jones, J. R.; Vale, Jim E.; Davidson, G. R.; Davies, D. Arthur; Wright, I. A. (2006)

An experiment was conducted to examine the effects of mixed grazing of sheep plus cattle under continuous stocking of permanent pasture at different sward heights. The experiment had a 2×3 factorial design, with two sward ...
Effect of sward type and management on butterfly numbers in the uplands

Davies, D. W. R.; Evans, J. G.; Fraser, M. D.; Vale, J. E. (1800)
Effect of sward type and management on butterfly numbers in the uplands

Fraser, M. D.; Evans, J. G.; Davies, D. W. R.; Vale, J. E. (2008)

A four-year systems experiment is quantifying the economic and environmental impacts of (a) mixed grazing of sheep with cattle, and (b) the removal of cattle from mixed systems on improved permanent pasture to graze ...
Effect of temperature stress on the endogenous cytokinin content in Arabidopsis thaliana (L.) Heynh plants

Todorova, Dessislava; Genkov, Todor; Vaseva-Gemisheva, Irina; Alexieva, Vera S.; Karanov, Emanuil N.; Smith, Aileen; Hall, Michael A. (2005)

The levels of three endogenous cytokinin equivalents: zeatin (Z), iso-pentenyladenine (iP) and dihydrozeatin (dZ) in two Arabidopsis thaliana (L.) Heynh genotypes — wild type (wt) and ethylene-insensitive mutant (eti5), ...
The effect of Texel Muscling QTL (TM-QTL) on meat quality traits in crossbred lambs

Lambe, N. R.; Macfarlane, J. M.; RIchardson, R.I.; Matika, O.; Haresign, W.; Bunger, L. (2010-08-01)

A quantitative trait locus (QTL) has been identified on chromosome 18 in Texel sheep (TM-QTL) that increases depth and area of the longissimus dorsi muscle. The study aimed to assess the pleiotropic QTL effects on key meat ...
The effect of Texel Muscling QTL (TM-QTL) on meat quality traits in crossbred lambs

Lambe, N. R.; Macfarlane, J. M.; Fisher, A. V.; Matika, O.; Haresign, W.; Bunger, L. (2010-08-01)
The effect of Texel Muscling QTL (TM-QTL) on meat quality traits in crossbred lambs

Lambe, N. R.; Macfarlane, J. M.; Fisher, A. V.; Matika, O.; Haresign, W.; Bunger, L. (2010-08-01)
The effect of the feed-to-buffer ratio on bacterial diversity and ruminal fermentation in single-flow continuous-culture fermenters

Cantalapiedra-Hijar, G.; Yanez-Ruiz, D. R.; Newbold, C. J.; Molina-Alcaide, E. (2011-02-19)
The effect of the feed-to-buffer ratio on bacterial diversity and ruminal fermentation in single-flow continuous-culture fermenters

Cantalapiedra-Hijar, G.; Yanez-Ruiz, D. R.; Newbold, C. J.; Molina-Alcaide, E.; Newbold, Charles (1800)
The effect of the feed-to-buffer ratio on bacterial diversity and ruminal fermentation in single-flow continuous-culture fermenters

Cantalapiedra-Hijar, G.; Yáñez-Ruiz, D. R.; Newbold, C. J.; Molina-Alcaide, E.; Newbold, Charles (2011-03)
Effect of the level of iodine in the diet of pregnant ewes on the concentration of immunoglobulin G in the plasma of neonatal lambs following the consumption of colostrum

Rose, Michael T.; Wolf, Basil T.; Haresign, William (2007-02-14)

Excessive I in the diet of pregnant sheep can reduce the concentration of antibodies in the blood plasma of the lambs after they have consumed colostrum. Our aim was to determine the dose of dietary I that would avoid this ...
Effect of the nitrification inhibitor nitrapyrin on the fate of nitrogen applied to a soil incubated under laboratory conditions

Adams, William A.; Shah, Z.; Abbasi, M. Kaleem (2003-08-14)

The aim of this study was to examine the effect of the nitrification inhibitor nitrapyrin on the fate and recovery of fertilizer nitrogen (N) and on N mineralization from soil organic sources. Intact soil cores were collected ...
The effect of the Texel Muscling QTL on live and carcass weight in Texel lambs

Macfarlane, J. M.; Lambe, N. R.; Haresign, W.; Bunger, L. (2012-03-12)

The Texel Muscling QTL (TM-QTL) is a QTL affecting loin muscling in Texel sheep with a paternal polar overdominant pattern of expression. This study on purebred Texel sheep used the first available data to include homozygote ...
The effect of the Texel Muscling QTL on live and carcass weight in Texel lambs

Macfarlane, J. M.; Lambe, N. R.; Haresign, W.; Bunger, L. (2012-06-12)

The Texel Muscling QTL (TM-QTL) is a QTL affecting loin muscling in Texel sheep with a paternal polar overdominant pattern of expression. This study on purebred Texel sheep used the first available data to include homozygote ...
The effect of three muscling Quantitative Trait Loci on growth patterns of cross-bred lambs

Lambe, N. R.; Macfarlane, J. M.; Masri, A.; Matika, O.; Haresign, W.; Bunger, L. (2009)
The effect of three muscling Quantitative Trait Loci on growth patterns of cross-bred lambs

Lambe, N. R.; Macfarlane, J. M.; Masri, A.; Matika, O.; Haresign, W.; Bunger, L. (1800)
