On the analysis of dacron bag data for low degradability feeds
Grass and Forage Science - Tập 43 Số 4 - Trang 441-444 - 1988
M.S. Dhanoa
AbstractThe effect of lag phase on the estimates of parameters from the analysis of dacron bags is investigated. Simultaneous estimation of the lag parameter within the McDonald model is shown to be advantageous.
Increased concentration of water‐soluble carbohydrate in perennial ryegrass (Lolium perenne L.): milk production from late‐lactation dairy cows
Grass and Forage Science - Tập 56 Số 4 - Trang 383-394 - 2001
L. A. Miller, J. M. Moorby, David R. Davies, M. W. Humphreys, Nigel Scollan, M.D. Hanigan, Michael K. Theodorou
Eight multiparous Holstein–Friesian dairy cows in late lactation were used to investigate the potential of using perennial ryegrass with a high concentration of water‐soluble carbohydrate (WSC) to increase the efficiency of milk production. After a pretreatment period on a common pasture, the cows were each given ad libitum access to one of two varieties of zero‐...... hiện toàn bộ
Individual and socially learned preferences for biserrula (Biserrula pelecinus L.) in sheep
Grass and Forage Science - Tập 70 Số 2 - Trang 374-380 - 2015
D. Thomas, J. T. B. Milton, C. K. Revell, M. A. Ewing, D. R. Lindsay
AbstractThis study examined how sheep develop a learned aversion to the annual legume biserrula (Biserrula pelecinus L.). Merino sheep were grazed on paddocks sown with either (i) biserrula, (ii) biserrula + ryegrass (Lolium rigidum Gaud.), (iii) crimson clover (Trifolium incarnatum L....... hiện toàn bộ
Selective defoliation by sheep according to slope and plant species in the hill country of New Zealand
Grass and Forage Science - Tập 58 Số 4 - Trang 339-349 - 2003
Ignacio F. López, John Hodgson, Duncan Hedderley, Ian Valentine, M. G. Lambert
AbstractThe objective of the study was to evaluate the grazing behaviour by sheep in hill country paddocks in New Zealand which had received two long‐term fertilization and stocking rate treatments [high fertility–high stocking rate (HH); low fertility–low stocking rate (LL)]. Herbage accumulation and selective grazing were evaluated within low slope (LS), medium s...... hiện toàn bộ
How do severity and frequency of grazing affect sward characteristics and the choices of sheep during the grazing season?
Grass and Forage Science - Tập 58 Số 2 - Trang 138-150 - 2003
Florence Garcia-Launay, Pascal Carrère, Jean‐François Soussana, René Baumont
AbstractThe effect of grazing frequency and severity on sward characteristics and preferences by sheep was investigated from April to September. Two levels of grazing severity were imposed by varying the numbers of ewes grazing 200 m2 plots for 24 h: four (S, severe) or two (L, lax) ewes. Grazing frequency was either 1 d week−1... hiện toàn bộ
The effect of ensiling and fractionation on the suitability for combustion of three common grassland species at sequential harvest dates
Grass and Forage Science - Tập 67 Số 4 - Trang 559-568 - 2012
J. McEniry, John Finnan, C. C. King, P. O’Kiely
AbstractIn a Green Biorefinery processing green biomass, one possible application for the press‐cake fraction is as biomass fuel for combustion. In an industrial setting, the preservation of herbage as silage and its subsequent fractionation i...... hiện toàn bộ
Does the “high sugar” trait of perennial ryegrass cultivars express under temperate climate conditions?
Grass and Forage Science - Tập 74 Số 3 - Trang 496-508 - 2019
M. Jordana Rivero, Óscar Balocchi, Cristian J. Moscoso, Juan Agustín Siebald, Fabián Lukas Neumann, Don Meyer, Michael R. F. Lee
AbstractThe objective was to evaluate water‐soluble carbohydrate (WSC) and crude protein (CP) concentration of perennial ryegrass (PRG) cultivars with different genetic potential fo...... hiện toàn bộ
The morphological and physiological responses of perennial ryegrass (Lolium perenne L.), cocksfoot (Dactylis glomerata L.) and tall fescue (Festuca arundinacea Schreb.; syn. Schedonorus phoenix Scop.) to variable water availability
Grass and Forage Science - Tập 67 Số 4 - Trang 507-518 - 2012
LR Turner, Meisha Holloway‐Phillips, RP Rawnsley, DJ Donaghy, Keith G. Pembleton
AbstractThere is a growing interest in the use of deficit irrigation and perennial pasture species other than perennial ryegrass (Lolium perenne L.) in temperate agriculture, in response to the decreasing availability of irrigation water. Deficit irrigation requires an understanding of plant responses to drought stress to ensure maximum d...... hiện toàn bộ
Leaf dynamics of timothy and meadow fescue under Nordic conditions
Grass and Forage Science - Tập 56 Số 3 - Trang 294-304 - 2001
Perttu Virkajärvi, Kirsi Järvenranta
Leaf production dynamics of timothy (Phleum pratense L. cv. Tarmo) and meadow fescue (Festuca pratensis Huds. cv. Kalevi) were studied in Finland under field conditions in mixed swards containing timothy, meadow fescue and red clover (Trifolium pratense L. cv. Björn) harvested by cutting. Fifteen randomly sele...... hiện toàn bộ
