Clover Pasture

During the spring of both 1968 and 1969 three phalaris-white clover pasture types, differing in botanical composition from clover-dominant to grass-dominant, were grazed by beef cattle. The cattle were scored twice a day for bloat incidence and severity and were weighed each month. No cattle died from bloat or any other cause. Of the 289 moderate and severe cases of bloat observed during the experiment, 221 occurred on the high clover pasture type (60-80 per cent white clover) ; comparable figures on the medium clover (30-50 per cent white clover) and low clover (15-25 per cent white clover) pasture types were 58 and 10 respectively. In addition to the greater incidence of bloat, liveweight gains on the highest clover pasture were 20-30 per cent lower than on the the other two pasture types in both years. The digestibility and availability of the herbage on the clover-dominant pasture equalled or exceeded that of pastures containing <50 per cent white clover ; reduced liveweight gains were attributed to a depressive effect of bloat on herbage intake.

Possible management strategies for areas of stubble left after hay had been harvested from a ryegrass/white clover pasture were studied in a trial on an irrigated Wakanui silt loam at Lincoln College, Canterbury. Following a hay crop cut in late December, the stubble was either trimmed to 2 cm (920 kg DM/ha) or left intact at 8-12 cm (2200 kg DM/ha) and spelled for either four or eight weeks. Subsequent regrowth herbage yield, botanical composition and digestibility were measured. The highest live herbage mass of 5380 kg DM/ha resulted from leaving the stubble intact and cutting the regrowth at four weekly intervals. The other treatments gave herbage masses from 4120 kg DM/ha to 4350 kg DM/ha but did not significantly differ from one another. However while 1220 and 1650 kg DM/ha of dead material was present in the "stubble intact" treatments, only 470 and 880 kg DM/ha occurred where the stubble was trimmed to 2 cm. The amount of dead material was the main determinant of overall digestibility, as the digestibility of the green herbage was similar (79-80%) for all treatments. As a result of differing amounts of dead material therefore, the herbage mass from trimmed stubble was from 4 to 10% higher in digestibility than that from the stubble left intact treatment. Clover proportion was high throughout the treatments, ranging from 50% in the long spelled treatment to 70% in the short spelled treatment. The results of this trial suggest that hay stubble should be left intact but regrowth should be closely defoliated after four weeks to maximise production and return the sward to a leafy state as quickly as possible.

Assessment of the relative performance of white clover (Trifolium repens L.) cultivars, using multi-year and multi-location seasonal growth trials, is key to identification of material with specific and broad adaptation. This paper is based on a multi-year and multi-location study of 56 white clover entries comprising 14 commercial cultivars and 42 experimental synthetic lines evaluated for seasonal growth under rotational grazing across four locations in New Zealand over 4years. The four locations (and animals grazing) were: Kerikeri (beef cattle), Aorangi (beef cattle), Ruakura (dairy cattle), Lincoln (sheep). Significant (P&lt;0.05) genotypic variation among the 56 entries, and genotype × year, genotype× location and genotype× season interactions, were estimated. We were able to identify cultivars and experimental synthetics with specific and broad adaptation to the three grazing management types. Cvv. AberDance, Apex, Demand, Prestige, Quartz and Riesling, with leaf size ranging from small to medium–large, showed highly above-average performance under sheep grazing. Synthetic lines 15 and 45 also had highly above-average performance under sheep grazing. Cvv. Legacy and Kopu II showed above-average performance under cattle and dairy grazing. Synthetics 15, 48, 49, 44, 22 and 18 and cv. Quartz had above-average performance under all three grazing managements. Synthetics 27, 33 and 38 had highly above-average performance across all three grazing managements and were superior to all 14 cultivars evaluated. Several of these superior synthetics are being tested across multiple grazing environments. Among the 14 cultivars evaluated, Legacy and Quartz showed superior seasonal growth performance across the three grazing managements. Quartz is being evaluated in several on-farm trials across temperate regions of the world.

Three herbicides, 2,2- DPA (2,2-dichloropropzonzc acid), diquat dibromide (9, l0-dihydro-8a, 10a-dizonia phenanthrene dibromide) and paraqmt di (methyl sulphate) (1,l-dimethl-4,4,-bipryridylium di (methyl sulphate) ) were tested with a view to controlling barley grass (Hordeum leporinum Link) in clover pastures. The tolerance of white clover (Trifolium repens L.) and subterranean clover (T. subterraneum L.) to sodium 2,2-DPA was determined. 2,2-DPA caused severe damage to subterranean clover (resulting in the loss of one season's production) and slight damage to white clover at a rate which controlled the grass-2 lb an acre acid equivalents. Diquat dibromide applied at 2 lb an acre (active cation) in mid winter gave complete control of barley grass in a subterranean clover pasture. Springfields of clover on treated plots were double those of the unseated control. Paraquat di (methyl sulphate) gave satisfactory control of barley, grass at 0.5 lb an acre, as an early post emergence spray, with no increase in subterranean clover yields, At the 1 lb an acre rate barley grass control was complete.

A nursery of single species and simple mixtures of 12 grasses and 9 legumes at Beerwah on the coastal lowlands of southern Queensland was grazed by sheep for over 16 years. For the last eight years 25.8 wethers a hectare (10.5/acre) were carried and thrived, heavy grazing pressure being maintained. Changes in botanical composition were recorded. The final mixture was dominated by Trifolium repens and Paspalm notatum. Other species to survive were Digitaria decumbens, Pennisetum clandestinum, Paspalum wettsteinii, and Brachiaria mutica. The majority of species failed to survive the close intense grazing by sheep. Annual replacements of phosphorus, sulphur, calcium, and potassium were made but nitrogen was never applied, and the highly productive pasture was maintained by legume nitrogen, mainly from white clover. Soil fertility improved under the pasture.

Hill country pasture was grazed by the following ratios of goats and sheep from 1979-l 983: 100% goats (Goat 100). 66% goats and 34% sheep (Goat 66)) 33% goats and 67% sheep (doat 33), 100% set-stocked sheep (Sheep 100) and 100% mobstocked sheep. Changes in botanical composition, herbage mass and herbage accumulation rate were measured by sample dissection, visual estimation and trimmed exclosure cages respectively on three slope classes (banks, slopes and tracks). Pastures grazed by goats developed Yorkshire fog IHolcus lanatus)- white clover (Trifolium repens L.) associations with strong white clover growth on all slope classes unlike sheep-grazed pastures which contained little white clover and were dominated by perennial' ryegrass (Lolium perenne L.) and browntop (Agrostis tenuis Sibth.). The herbage mass of 3000, 1830, 1410 kg DM/ha on banks, slopes and tracks respectively for Sheep 100 pastures contrasted with that on the Goat 100 pastures of 2030, 3750 and 4300 kg DM/ha. White clover was enhanced on all slope classes in the Goat 100 treatment. Annual herbage accumulation was greater on the Goat 100 than Sheep 100 pastures, 13.9 and 11.2 t DM/ha respectively. There was a close association between increased annual white clover accumulation and tofal herbage accumulation. The complementary nature of sheepandgoatgrazing behavioursuggeststhe possibility of increased meat and fibre production from mixed grazing. The implications of these results for future research are discussed. Keywords: Sheep, goats, herbage mass, herbage accumulation rate, botanical composition, slope classes, white clover (Trifolium repens L.), perennial ryegrass (Lolium perenne L.), Yorkshire fog (Holcus lanatusl, browntop (Agrostis tenuis Sibth.).

Species Mixtures

Animal production is commonly reported to increase when different animal species are grazed together on the same pasture (Nolan and Connolly 1977). In such experiments there is often a difficulty with interpretation of results due to a failure to establish equal grazing pressures between species mixtures, and confounded production differences may result. The theory behind the design of mixed experiments continues to pose problems (Connolly and Nolan 1976, Connolly 1984).The experiment reported here was designed to investigate whether, when different animal species are grazed at the same pressure, there are differences in animal intake and/or diet composition when they are grazed singly or in mixtures.Nineteen, 18-month-old steers, 40 yearling wether goats and 40 10-month-old wether sheep were grazed in New Zealand on a mature summer ryegrass/white clover pasture (4550 kgDM/ha) in 5 treatments: cattle alone (CA), sheep alone (SA), goats alone (GA), and cattle with sheep (CS, SC) and cattle with goats (CG, GC).
