SUMMARYThe performance of Welsh Mountain ewes and their single Clun-cross lambs on swards of perennial ryegrass (Lolium perenne L.), cocksfoot (Dactylis glomerata L.), tall fescue (Festuca arundinacea Schreb.) and timothy (Phleum pratense L.) was studied over 3 years (1975–1977) at a site 305 m O.D. in mid-Wales. Under a rotational grazing regime at a fixed stocking rate of 25 ewes and lambs/ha, mean daily lamb live-weight gain over the 84 days experimental period from early May to late July was 24 g higher on timothy than on perennial ryegrass and tall fescue and 35 g higher than on cocksfoot. Averaged for the 3 years the mean daily lamb live-weight gains were 194, 170, 170 and 159 g on timothy, perennial ryegrass, tall fescue and cocksfoot respectively. There were, however, marked interactions with years.Ewe live-weight change varied considerably between grasses and years with cocksfoot poorer than timothy and perennial ryegrass. Mean ewe live-weight change ranged from an overall loss of 39 g/day in 1975 to a gain of 34 g/day in 1977.Differences detected in animal performance between the four grass species altered during the 84 days of the experiment. Timothy and to a lesser extent tall fescue produced better animal performance early in the season whereas perennial ryegrass came into prominence during July.The results are discussed in relation to the present and potential use of the grass species under upland conditions.

SUMMARYHerbage characteristics of perennial ryegrass (Lolium perenne L.), cocksfoot (Dactylis glomerata L.), tall fescue (Festuca arundinacea Schreb.) and timothy (Phleum pratense L.) pastures were obtained whilst rotationally grazed by ewes and their single lambs at a fixed stocking rate of 25/ha on an upland site (305 m O.D.) in mid-Wales. Drymatter production of cocksfoot averaged 32·1 kg/ha/day over the 3-year duration of the trial (1975·7) and was 13·3 kg/ha/day lower than that of the other three grass species. This resulted in a 8 kg/ha/day reduction in dry-matter intake on cocksfoot; this was significantly lower (P < 0·05) than that achieved on the other grasses, which were similar to one another around 36 kg/ha/day.In vitro digestibility of the herbage ranked in the order perennial ryegrass > timothy = cocksfoot > tall fescue. Intake of digestible organic matter (DOMI) was lower on cocksfoot than on perennial ryegrass and timothy. Differences were also detected in crude protein, water-soluble carbohydrates and sodium composition between species.Dry-matter intake was positively correlated with herbage growth rates (r = 0·95, P < 0·001) but not to digestibility of herbage on offer (r = 0·18). Both ewe and lamb live-weight gains were positively related to intake of dry matter and DOMI.Reference is made to comparative yield data between the grasses obtained under cutting trials. In the 2nd and 3rd harvest years (1967–1967) growth rates in the grazing experiment were 76, 61, 81 and 80% of the 66·2, 66·7, 67·8 and 65·0 kg D.M./ha/day obtained under a cutting regime on perennial ryegrass, cocksfoot, tall fescue and timothy swards respectively. This illustrates the danger involved in assessing the potential of grasses based on such information.The results are discussed in relation to the value of the species for use under grazing in the uplands.

Studies were conducted on the host plants of four billbug species (Coleoptera:Curculionidae: Sphenophorus parvulus Gyllenhal, S. venatus Chitt., S. inaequalis Say, and S. minimus Hart) found on New Jersey turfgrasses. A collection of 4803 adults from pure stands of various turfgrasses revealed all four billbugs on Kentucky bluegrass (Poa pratensis L.), tall fescue (Festuca arundinacea Schreb.), and perennial ryegrass (Lolium perenne L.), and S. parvulus, S. venatus, and S. minimus on Chewings fescue (F. rubra L. ssp. commutata Gaud.). Since the presence of larvae, pupae, or teneral adults more accurately indicates the host status of a grass species, immature billbugs were collected from plugs of the various grass species and reared to adults for identification. All four species were reared from immature billbugs found in Kentucky bluegrass turf; immatures of S. venatus, S. inaequalis, and S. minimus were found in tall fescue; S. venatus and S. minimus in perennial ryegrass; and S. inaequalis in strong creeping red fescue (F. rubra L. ssp. rubra). A laboratory experiment was also conducted in which billbug adults were confined in petri dishes with either Kentucky bluegrass, perennial ryegrass, tall fescue, or bermudagrass (Cynodon dactylon Pers.). Only minor differences were found between the four grasses in billbug survival, number of eggs laid, and amount of feeding. In general, bermudagrass was the least favored host and the other grasses were equally adequate hosts. The results of this study indicate a need for updating host-plant lists of these four billbug species.

Recent Discussion

Recent discussion about pasture persistence concentrates on pastures based on perennial ryegrass, the most commonly used grass species. This paper raises the question as to whether some of the causes of poor pasture persistence are due to perennial ryegrass being used in environments to which it is not suited. The adaptation to environmental stresses, particularly water, temperature and nutrient deficiencies, in different regions of New Zealand of tall fescue, cocksfoot, phalaris, and lucerne are discussed, and how this impacts on persistence advantages over perennial ryegrass.

A grazing study was conducted, over a 3-year period (1997–99), on the subtropical north coast of New South Wales, Australia, to compare the yield of prairie grass (Bromus willdenowii cv. Matua), tall fescue (Festuca arundinacea cv. Vulcan) and perennial ryegrass (Lolium perenne cv. Yatsyn), on a well-drained red krasnozem soil at Wollongbar Agricultural Research Institute (WAI) and on a heavy clay soil at Casino. The effect of grazing interval (equivalent to the time taken to regrow 1.5, 2.5 or 4 leaves/tiller) in spring, and forage quality of prairie grass in winter and spring was also assessed. At both sites, the dry matter (DM) yields of prairie grass over the establishment year and in year 2 were significantly (P<0.001) higher than for the other 2 grass species (mean for 2 years over the 2 sites was 23.8, 8.9 and 7.7 t DM/ha for prairie grass, ryegrass and tall fescue, respectively). In year 3, there was no production of tall fescue or ryegrass at the WAI site while prairie grass produced 11.3 t DM/ha although this was obtained from natural seedling recruitment after the sward was sprayed with a herbicide in February of that year. At the Casino site, ryegrass and tall fescue still made substantial growth in year 3 (3.1 and 2.1 t DM/ha for ryegrass and tall fescue, respectively) but this was significantly below the yields of prairie grass (5.5 t DM/ha). More frequent grazing of prairie grass in spring (equivalent to 1.5 leaves/tiller of regrowth) led to significantly (P<0.05) less plants surviving summer and less seedling recruitment in the following autumn. The annual yield of the 1.5 leaf treatment was significantly (P<0.05) lower than the remaining treatments but only in the third year of the study. Analysis of prairie grass forage samples, taken in June (vegetative sward) and November (reproductive sward), gave magnesium values of less than 0.2% DM which is below the concentration found in ryegrass and that recommended for dairy cattle. The Ca : P and K : (Ca + Mg) ratios in prairie grass improved, as a forage for dairy cows, with regrowth time up to 5 leaves/tiller. Metabolisable energy remained constant with regrowth time in June at 10.8 MJ/kg DM but fell significantly in November from 10.7 MJ/kg DM, immediately post-grazing, to 9.2 MJ/kg DM at the 4.5 leaves/tiller stage of regrowth. In contrast to observations in ryegrass, the water-soluble carbohydrate content of forage samples of prairie grass taken in November showed a substantial increase with regrowth time to over 12% DM at the 3 leaves/tiller stage of regrowth. The high productivity and forage quality of prairie grass obtained over a 3-year period suggests this grass species could be a suitable temperate perennial grass for subtropical dairy pastures. An appropriately long grazing interval in spring seems critical to optimise plant survival over summer and for adequate seed set for seedling recruitment the following autumn. If summer weeds and/or grasses invade to a significant extent, the large seedbank of prairie grass provides the opportunity to spray out the pasture in summer and rely on seedling recruitment to establish a new sward in autumn. The forage quality of prairie grass in winter and spring is similar to perennial ryegrass but the magnesium levels are substantially lower and stock grazing this type of pasture for extended periods would need to be supplemented with this mineral.

1 SUMMARY Selenium is considered an essential element for the life of animals, including humans. Anyway, its necessity and function in the plant organism have not been fully explained yet. The aim of the work was to investigate an effect of foliar application of selenium on the infestation of the perennial ryegrass and tall fescue by fungal pathogen Fusarium culmorum based on a determination of ergosterol in plant biomass. Two major species of grass (perennial ryegrass and tall fescue) cultivated under defined climate chamber conditions were included in the experiment. Within 5 weeks from their germination, a solution of selenium in the form of selenite or selenate, corresponding to 4 mg/m2 Se, was foliarily applied onto the plants. After 14 days of spraying, a solution containing conidia of Fusarium culmorum was applied to the plants. Subsequently, samples of green matter were taken at 14-day intervals, and the content of ergosterol and selenium were determined there. The content of ergosterol, which was selected as a marker of fungal pathogens, was found to be significantly higher (P<0.05) on the 28th day after the selenite and selenate application in both grass species. This increase was conclusive (P<0.05), when compared to the control group. No difference was observed between the selenium forms used. From our experiment, it is clear the plants of the perennial ryegrass and tall fescue were more easily attacked by fungal pathogen Fusarium culmorum after the application of selenium. Thus, it is possible to assume the application of selenium acts as stress a factor to plants.

The results are briefly reported of seven comparative studies on aspects of pasture and animal performance from pastures based on Yorkshire fog (Holcus Zanatus), perennial ryegrass (Lofiurn perenne) or tall fescue (Festuca arundinacea) grown under adequate soil nutrient conditions (e.g., Olsen P 20-30 pg/g) and under continuous or rotational stocking by sheep. Pasture production, as measured by the stocking rate required to maintain specified sward conditions, was 2.5% greater on perennial ryegrass than on Yorkshire fog pastures, and 25% greater on Yorkshire fog than on tall fescue. Differences in liveweight gain and wool production in weaned lambs between pastures were relatively small and inconsistent, but levels of worm egg output were lower for lambs on Yorkshire fog than on tall fescue. The use of polyethylene glycol to bind condensed tannins reduced performance slightly in lambs on Yorkshire fog and tall fescue, but not those on perennial ryegrass.

SUMMARYFour grass species, three hybrids and three mixtures were grown in field swards near Aberystwyth. All swards were amply supplied with nutrients and were cut at 5-week intervals during the year of sowing (1989) and during the following 4 years. The order of the grasses in rate of establishment was: Westerwolds ryegrass > Italian ryegrass (Lolium multiflorum) > Italian ryegrass × perennial ryegrass, Italian ryegrass × meadow fescue, perennial ryegrass (Lolium perenne) > perennial ryegrass × meadow fescue, meadow fescue (Festuca pratensis) > tall fescue (Festuca arundinacea). During the sowing year as a whole, Italian ryegrass was the highest yielding grass, followed by Westerwolds ryegrass. During the remaining period (1990–93), as a whole, the highest yields were obtained from perennial ryegrass sown alone or in a mixture with tall fescue. Tall fescue sown alone was one of the lowest yielding grasses in the year of sowing, but developed to be the highest yielding in 1992 and 1993. Westerwolds ryegrass persisted least well, although some plants did survive until 1992. Italian ryegrass persisted better than Westerwolds and Italian ryegrass × meadow fescue persisted better than Italian ryegrass. Hybrid ryegrass and perennial ryegrass × meadow fescue persisted satisfactorily but with fewer tillers/m2 than perennial ryegrass or tall fescue. The yield of tall fescue in March was as high as that of Italian ryegrass in 1990 and 1991 and higher than that of any of the other grasses in 1992 and 1993; the tiller density of tall fescue was particularly high in March. The yield of mixtures (Italian ryegrass with perennial ryegrass, Italian ryegrass with tall fescue and perennial ryegrass with tall fescue) was, on average, 2·5% more than the mean of the component species when sown alone. When grown with ryegrass, tall fescue was not prominent initially but its proportion in the sward gradually increased.

SUMMARYCobs and pellets which differed in particle size (modulus of fineness, MF) were prepared from dried perennial ryegrass and tall fescue and given to sheep. The MF values of the feeds were 2·45,1·09,0·81 and 0·74 for perennial ryegrass and 2·28,0·84,0·67 and 0·57 for tall fescue. Organic matter digestibility was similar for the two grass species when measured in vivo, but when measured in vitro values for perennial ryegrass were about 3 units higher than those for tall fescue. Voluntary intake and live-weight gain were higher for sheep given tall fescue, the difference in live-weight gain being just significant at P < 0·05. The response to change in particle size was similar for the two grass species. Intake was lowest and digestibility highest for the feeds with the highest MF, but differences between the three finely-ground forms of each species were not significant. There was a tendency for the intake of digestible organic matter to be lower for the feeds with lowest MF than for those with intermediate values for MF. The rate of passage of undigested particles was slower for cobs with the highest MF than for the other feeds, which did not differ significantly one from another.

The grazing response of ewe hoggets offered tall fescue, endophyte-infected (+E) or endophyte-free (-E) perennial ryegrass all sown with white clover into a fertile silt loam was examined in April 1990. In a second experiment 2 grazings were observed where 5 grasses had been overdrilled into old lucerne growing on stony infertile land. Pregnaht ewes (August) and ewes with young lambs (October) grazed 3 replicates of tall fescue, +E perennial ryegrass, cocksfoot, phalaris and prairie grass. After the August grazing nitrogen fertiliser was applied at 0 and 300 kg N/ha to 5 x 2 m subplots in each 30 x 9 m grass plot. April observations showed that on day one 76% of grazing time was on tall fescue. During the first 4 days of grazing grass leaf height decreased 60 mm in tall fescue, 43 mm in +E and 42 mm in -E ryegrass while in the last 5 days decreases were 5, 3 and 25 mm. Over the 9 days' grazing, pseudostem height declined 5.2, 1.5 and 5.0 mm, green grass cover from 62 to 30,65 to 44, and 68 to 33%, and herbage removal was 940, 1100 and 1300 kg DM/ ha from tall fescue, +E and -E ryegrasses. During the first 3 days of the August grazing, grass leaf heights of cocksfoot and +E ryegrass declined at a much slower rate than in the other 3 species. The October grazing showed a similar defoliation pattern on plots without N. Addition of 300 kg N/ ha resulted in very rapid defoliation of all 5 species during the first day of the 7-day grazing period. April grazing showed that initially sheep preferred tall fescue. Even though grazing time was similar for +E and -E ryegrasses the hoggets consumed less +E than -E ryegrass, possibly owing to reluctance to penetrate the +E pseudostem horizon. The August and October grazings demonstrated the ability of sheep to discriminate between grass species and strong rejection of cocksfoot and +E ryegrass. However, N at a rate similar to a urine patch produced leaf in all species which was equally attractive to sheep. The reduced intake of +E ryegrass measured in the April grazing may explain some of the lower animal performance of sheep on +E ryegrass pastures. Equally, grazing preference shown by rate of canopy height decline in any pasture is probably highly correlated with pasture intake and animal productivity.

Relative to perennial ryegrass, tall fescue has increased summer production, pest resistance and persistency under summer dry conditions. The new cultivar 'Grasslands Roa' also has attributes of increased crown rust resistance and a high acceptability to stock. Animal performance has proved similar to that of perennial ryegrass with no stock health problems. Roa has very slow growth and no other grass species should be included in the seed mixture; the seed should be well covered at sowing: N fertiliser could be used to speed seedling growth; grazing should be frequent and lax with young stock during the first year to allow adequate root development. Methods of use of Roa are discussed. Keywords: Festuca arundinacea, Roa tall fescue, potential, selection, summergrowth, drought tolerance, establishment management.
