Measurement Period

Grasslands Kara cocksfoot, Grasslands Nui ryegrass, Grasslands Roa tall fescue, Grasslands Gala grazing brome and Grasslands Maru phalaris were sown as single grass species with either white or Caucasian clover during December 1993, on a Lismore stony silt loam in Canterbury. Plots were irrigated and rotationally grazed by sheep. Total herbage produced during the first measurement period (September 1994 to July 1995) averaged 13.6 t DM/ha. All white clover-based swards produced similar yields, but with Caucasian clover, phalaris-based swards produced the most and ryegrass and grazing brome the least. Production tended to be lower from pastures sown with Caucasian than white clover (12.9 cf. 14.2,kg DM/ha). During the second measurement period (July 1995 to May 1996) total production was similar with both legumes. When evaluated over both measurement periods, phalaris and tall fescue gave the highest and cocksfoot and ryegrass the lowest production when sown with white clover, while cocksfoot and grazing brome were the lowestproducing swards with Caucasian clover. Ten --months-after-sow.ing,-white-cIover-contributed-in excess of40% of the DM in all swards except with ryegrass and grazing brome where it contributed 20%. The proportion of white clover then declined in all pastures over the following 20 months, ryegrass-based swards having the highest (10%) and cocksfoot the lowest (1%). When sown with Caucasian clover the legume content of swards increased during the 12 months from spring 1994 in swards containing phalaris, tall fescue and grazing brome. The proportion of legume in -cocksfoot swardsmdeclined-continuously from 22 to 4% over the 20 months while it increased continuously from 4 to 28% with ryegrass. The legume content in lo-month-old pastures was higher when sown with white than with Caucasian clover but this ratio was reversed by 28 months. This occurred with all pasture types but was most pronounced with ryegrass and cocksfoot pastures. The present experiment shows Caucasian clover can make a major contribution in irrigated pastures in Canterbury.

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.

Pasture Production

This study measured total dry matter production and botanical composition of binary mixtures of cocksfoot (Dactylis glomerata), ryegrass (Lolium perenne) or tall fescue (Festuca arundinacea), as a replacement series in proportions of 100:0, 75:25, 50:50, 25:75 and 0:100 from June 1987 until May 1993. The binary mixtures were sown in March 1986 with white clover, on an occasionally drought affected Kaweku silt loam, with an average annual rainfall of 750 mm near Riversdale, in Southland. Mixtures with ryegrass were allowed a 6-month establishment period before ryegrass was overdrilled in early October 1986. Total yields of ryegrass/cocksfoot mixtures increased as ryegrass seeding rate increased. Clover yields were generally unaffected. Mixtures of cocksfoot/tall fescue produced more sown grass than either species sown alone. This lowered clover and other grass yields, resulting in no total dry matter yield improvement in mixtures compared to pure sowings. Tall fescue/ ryegrass mixtures were competitive in winter and spring with lower total yields than either species sown alone. This competition also lowered other grass yields. During summer and autumn the total production increased as the amount of ryegrass increased. Seed mixtures with two perennial temperate pasture grasses did not provide any extra pasture production in a cool temperate environment under infrequent hard grazing management. The best choice for the region would be the grass that provided the greatest dry matter yield. Other components such as clover may be reduced when mixing grasses.

An experiment was conducted on a fertile Walcanui silt loam in 1991/92 to examine the productivity of 4 perennial pasture grass species, Grasslands Roa tall fescue (Festuca arundinacea), Grasslands Marsden hybrid tyegrass (Lolium perenne x Lolium hybridum), Grasslands Maru phalaris (Phalaris aquatica), Grasslands Wana cocksfoot (Dactylis glomerata), and 2 binary mixtures, tall fescue plus cocksfoot and phalaris plus cocksfoot. Between July 1991 and September 1992 the highest production came from phalaris plus cocksfoot at 19.05 t DM/ha. Hybrid ryegrass, phalaris, tall fescue plus cocksfoot, cocksfoot, and tall fescue produced 17.44, 17.13, 16.96, 14.17, and 13.13t DM/ha respectively. The botanical composition of both mixtures averaged equal proportions of the sown species. The proportion of cocksfoot increased over the summer period then declined for the following autumn/winter period. The experiment shows that simple pasture grass mixtures may be highly productive. These findings support the increasing farmer practice of sowmg some pasture grasses in simple mixtures.

Nematode Parasites

Increasing resistance of gastro-intestinal nematode parasites to anthelmintics and consumer resistance to the possibility of residues in animal products have prompted research on the effect of pasture species on nematodes and animal performance. Lambs (either infected with high rates of gastrointestinal nematodes or maintained nematode-free) were grazed on pure swards of chicory, high- or low-endophyte ryegrass, cocksfoot, tall fescue, lucerne, lotus, white clover or plantain. Infected lambs that grazed chicory had lower faecal egg counts and adult nematode populations, and higher carcass weights, than lambs grazed on plantain or the grass species; lambs that grazed legumes generally had intermediate counts, populations and weights. When kept parasite-free, carcass weights were up to 48% greater than in the nematodeinfected treatments. On farmlets run over 3 years, substituting 30% of the ryegrass area with lucerne or replacing the ryegrass with a multi-species mix consisting predominantly of bromes, tall fescue, phalaris, timothy and red and white clover, had no effect on gastrointestinal nematode larvae, lamb faecal worm egg or adult nematode numbers. It is concluded that a diet of pure chicory affects internal parasite populations but the small proportion included in the farmlet studies had no effect.

This experiment compared the productivity of caucasian or white clover when established with five perennial grass species over 6 years in a dry lowland environment. Hexaploid 'Endura' caucasian clover or 'Grasslands Demand' white clover were sown in December 1994 with high endophyte 'Yatsyn' perennial ryegrass, 'Grasslands Wana' cocksfoot, 'Grasslands Advance' tall fescue, 'Grasslands Gala' grazing brome, or 'Grasslands Maru' phalaris into a deep, fertile silt loam. Initial establishment of clovers was poor with ryegrass and grazing brome. Some volunteer white clover established in all 10 treatments. After the first 14 months, no irrigation was applied over the following 4 years. Sheep grazed plots about six times each year. The legume cover in 15-month-old pastures was higher when sown with white clover (29%) than caucasian clover (21%) but dry conditions during 1997/1998 (60% of 680 mm mean annual rainfall) and 1998/1999 (66% of mean rainfall) decreased the percentage of legume in white clover pastures. In February 1998 and March 1999, legume contributed 37% and 21% of the dry matter (DM) in caucasian clover pastures, but only 4% and 1% in pastures sown with white clover. Rainfall during the sixth season (1999/2000) was more favourable (111% of mean rainfall). Total DM production from July 1999 to June 2000 was 10.0 t DM/ha from caucasian clover pastures and 8.7 t DM/ha from pastures sown with white clover. The mean proportion of legume in white clover pastures ranged from 9% when sown with ryegrass and phalaris to 1% with cocksfoot. In contrast, mean caucasian clover legume contents were similar across all grass treatments at 20%, but reached 46% with cocksfoot during summer. It was concluded that caucasian clover is more tolerant of summer moisture stress than white clover when in association with perennial grass species.

Forty samples of grass silages, made from the five most widely used grass species in ruminant nutrition (<I>Dactylis glomerata</I> L.,<I>Phleum pratense</I> L., <I>Lolium perenne</I> L., <I>Festuca arundinacea</I> L. and hybrid Felina) were tested in the present study. These grass species conserved by an ensiling process were compared among each other according to dry matter (DM) rumen degradability parameters (<I>a</I> = portion of DM solubilized at initiation of incubation, <I>b</I> = fraction of DM potentially degradable in the rumen, <I>c</I> = rate constant of disappearance of fraction b and ED<sub>DM</sub> = effective degradability of DM, estimated for each ingredient assuming the rumen solid outflow rates of 0.02 (ED<sub>DM2</sub>), 0.05 (ED<sub>DM5</sub>) and 0.08 (ED<sub>DM8</sub>) h<sup>–1</sup>). Based on the chemical composition of grass silages the regression equations for prediction of ED<sub>DM</sub> were evaluated. The influence of the ensiling process on dry matter degradability parameters was also assessed. The best values of ED<sub>DM</sub> were determined for <I>Lolium perenne</I> (ED<sub>DM2</sub> = 753.2, ED<sub>DM5</sub> = 631.1 and ED<sub>DM8</sub> = 567.7 g/kg DM). The best predictor was NDF (<I>R</I><sup>2</sup>-values of 0.757 (ED<sub>DM2</sub>), 0.863 (ED<sub>DM5</sub>) and 0.906 (ED<sub>DM8</sub>)). Using two predictors the accuracy level increased. The combination of CF and NDF gave <I>R</I><sup>2</sup>-values 0.892, 0.920 and 0.929 for ED<sub>DM2</sub>, ED<sub>DM5</sub> and ED<sub>DM8</sub>, respectively. The regression equations based on the most important grass species harvested in different vegetation periods seem to be a useful tool for practical use. No significant <I>P</I> < 0.05) effect of the ensiling process in relation to dry matter rumen degradability parameters was proved.

Prairie Grass

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.

Farmers are aware of the increasing amount of information comparing alternative cultivars in dry environments in New Zealand. Animal production data in cool moist environments was unknown. To compare relative animal performance six different grasses were sown with Grasslands Tahora white clover (Trifolium repens L.) in 0.25 ha plots in two replicates in December 1988 at the Gore Research Centre in Southland. The six grasses were Grasslands Nui perennial ryegrass (Lolium perenne L.), Grasslands Roa tall fescue (Festuca arundinacea L)., Grasslands Kara cocksfoot (Dactylis glomerata L). Grasslands Matua prairie grass (Bromus willdenowii Ku&), Grasslands Hakari upland bmme (Bromus sitchensis), and Grasslands Kahu timothy (Phleum pratense L). These pastures were rotationally grazed with goats through spring and summer of the following two years; 2-weekly liveweight gain of 10 goats was recorded. Stocking rate was estimated from the addition of extra goats each week to achieve a residual pasture height of 100 mm. Spring liveweight gains (mid Sept-late Nov) were greatest on timothy and least on prairie grass. Stocking rate in spring was highest on the upland brome and tall fescue pastures and lowest for prairie grass and timothy pastures. Prairie grass pastures produced less total liveweight gain per ha than the other pastures. During summer, goat liveweight gains were ranked similarly to spring. Stocking rates were greatest on upland brome, and lowest on tall fescue. Total liveweight gain per ha in summer was greatest on the timothy pastures and least on prairie grass pastures.

Two trials to compare the seasonal and total production of a selected number of lines of tall fescue (Fescuca arundinacea) were conducted at Canberra, A.C.T., over the period 1961-1967. In the first trial 19 lines, 10 of Mediterranean and 9 of non-Mediterranean origin, were compared under replicated spaced plant conditions for two years. The yields of three Mediterranean lines C.P.I. 18948 (Algeria), 18952, and 18954 (Morocco) were significantly greater than any other line except in 1962 when C.P.I. 26996 (Scotland) and Goar's fescue (C.P.I. 27202) were as productive. In the second trial four of the most productive Mediterranean lines of tall fescue, CV. Demeter, one line of Dactylis glomerata and two lines of Phalaris tuberosa were compared in simulated sward conditions at Canberra from 1965 to 1967. In 1966, a favourable year, production in the Mediterranean tall fescues was little below that of the two phalaris lines, but in 1965 and 1967, both drought years, winter and total production were significantly less. Plant survival in the Algerian and Moroccan tall fescues was greater than in all other grasses in the trial.

Foxtail barley (Hordeum jubatum L.) is a troublesome weed in irrigated pastures. Several grass species seeded on two irrigated pastures at Lethbridge to test their ability to compete with foxtail barley. Tall fescue (Festuca arundinacea Schreb.) and creeping foxtail (Alopecurus arundinaceus Poir) reduced foxtail barley groundcover significantly compared to orchardgrass (Dactylis glomerata L.), pubescent wheatgrass (Agropyron trichophorum (Link) Richt.) and western wheatgrass (Agropyron smithii Rydb.); therefore, seeding of these grasses in areas subject to foxtail barley invasion should be encouraged.
