Autumn Management Of Grass-Legume Pasture, D P. Belesky, J M. Fedders, A S. Laidlaw
Autumn Management Of Grass-Legume Pasture, D P. Belesky, J M. Fedders, A S. Laidlaw
IGC Proceedings (1977-2023)
Duration of autumn grazing may affect the long-term balance of grass and legume in a sward. Effects of early and late autumn closing dates were studied on productivity and morphology of orchardgrass (Dactylis glomerata) and white clover (Trifolium repens) in replicated grazed swards. Early-closed paddocks continued to accumulate herbage during autumn, resulting in greater winter senescence than late-closed paddocks. Spring-cut herbage mass was not affected by autumn management; however, late closing had significantly more clover than early closing. Early-closed paddocks were grass domlnanl, with few relatively large tillers and few clover growing points compared with late-closed …

Dynamics Of Stylosanthes Species In Mixed Pastures In A Marginal Environment, J G. Mcivor, C J. Gardener
IGC Proceedings (1977-2023)
The growth and population dynamics of Stylosanthes hamata cv. Verano and S. scabra cv. Seca were measured in mixed, oversown pastures at Hillgrove (AAR=535 mm) near Charters Towers. Over a 10-year period mean stylo yields ranged from 20 kg/ha to 1800 kg/ha. During the first 3 years Verano outyielded Seca but in the last 7 years Seca had greater yields. Plant density was greater for Verano lhan Seca during the early years but the situation was reversed in later years. The Seca plants lived longer than Verano plants and there was a greater proportion of perennial plants in the Seca …

Analysis Of A Natural Pasture Of The Karst Region (North-East Italy) Under Chemical Fertilization, G Parente, R Ardiani, F Bozzo, M Onofrii, M Scimone, S Venerus
IGC Proceedings (1977-2023)
To characterise the vegetation changes in a natural pasture, a mineral fertilisation and a 4-year grazing test (1987-1990) were carried out on a typical karstic natural grassland, at that time not grazed by livestock and frequently devastated by fire. Mineral fertiliser and year-long animal grazing have modified the vegetation and seem not to have damaged the agro-ecosystem. An increase of the Arrhenatheretum species and, consequently, higher dry matter production, have been recorded, as well as an extension of the growth period and a greater quantity of grass during the summer. Animal performance has been quite satisfactory as the milk production …

A Grazing Land Conservation Plan, R G. Hendricks
IGC Proceedings (1977-2023)
In a sample planning scenario, a ranching operation in the USA demonstrates a typical conservation problem on grazing lands. Using SCS conservation planning techniques, problems and objectives are identified, resources are inventoried, data are analysed, solutions formulated and conservation practices implemented to solve the resource problem. With use of the economic analysis routine in Grazing Land Applications (OLA) version 1.1 decision suppott software, return on investment was largest when the client installed a combination of rest-rotation grazing, prescribed burning, and initiated a hunting lease programme.

IGC Proceedings (1977-2023)
The USDA-Soil Conservation Service has responsibility for providing one-on-one conservation planning assistance with the private rangeland managers of over 160 million ha in the USA. This assistance is provided on voluntary basis at the request of the private land user through a local conservation district. Through SO years of experience, a successful planning process has evolved, known as the Ten Elements Of Conservation Planning. These elements are: (1) provide information, (2) request assistance, (3) develop resource inventories, (4) recognise problems and opportunities, (5) determine objectives, (6) develop and evaluate alternatives, (7) make decisions, (8) document decisions, (9) implement decisions, and …
Use Of Objective Planning Techniques In The Development Of Large Livestock Farm In New Zealand, K I. Lowe
Use Of Objective Planning Techniques In The Development Of Large Livestock Farm In New Zealand, K I. Lowe
IGC Proceedings (1977-2023)
Limestone Downs is a sheep and beef cattle property of 3200 ha near Port Waikato, and provides funds for the C Alma Baker Trust for "the furtherance of the science of agriculture". A development programme slatted in 1981 transformed the farm from an extensive "station" into an intensive farming operation, lifting animal performance and financial returns. This followed the adoption of well-proven and relatively inexpensive modifications to management. Similar programmes should have realistic goals, and established decision rules with priorities. These should be supported by an appropriate monitoring programme and the use of objective data in decision making.

Effect Of Inoculants And Absorbents Incorporated In Grass Silage On Silage Quality, Effluent Production And Animal Performance, Raymond Jones
IGC Proceedings (1977-2023)
Unwilled ryegrass crops (151 kg DM) were enslled in 70-t bunker silos. Crop analysis (g/kg/DM) was water-soluble carbohydrates 153, nitrogen 24.1 and predicted digestibility (DOMD) 0.67. Molassed sugar beet feed pellets were incorporated at a rate of 25 kg/t in the harvested crop with or without inoculant treatment ("Live Systems", MMB, UK), and compared with a control silage with no additive. Absorbent addition with or without inoculant significantly reduced silage pH and ammonia-N compared with the control. Inoculant treatment further increased lactic acid content. Silage effluent production was reduced by up to 33% by absorbent inclusion with effluent DM losses …
Economics - The Neglected Dimension Of Pasture Disease R&D, N D. Macleod
Economics - The Neglected Dimension Of Pasture Disease R&D, N D. Macleod
IGC Proceedings (1977-2023)
Pasture utilisation underpins a significant contribution of livestock industries to Australia’s economic well-being. Pasture disease represents a direct threat to these enterprises but the economic magnitude of this threat remains largely unknown as the contribution of agricultural economics to pasture disease R&D, management and policy making has been minimal to date. Some insights to explain this apparent neglect are highlighted and a suggestion is made for a multiple disciplinary approach to R&D.

Forage And Animal Management Systems On Communal Rangelands In Arid And Semi-Arid Regions, Panjab Singh, A N. Ghosh
IGC Proceedings (1977-2023)
Grasslands and savannas, which comprise about 25% of the earth's land surface, are undergoing constant degradation, particularly in ar d and semi-arid regions. The rangeland resource is constantly sinking mainly because of its conversion to crop land, leaving farmer and pastorilist vulnerable to environmental extremes. This Paper presents the existing situation and the herbage and animal Product biomass of these regions. Climate and its impact on the Vegetation are discussed. Prevalent systems of rangeland use by sedentary and nomadic herdsman are considered and the constraints 0 the system are enumerated. Livestock 'rearing has been the most important occupation in these …

Autumn Grass Growth- The Effect Of Rest Interval, R Neilan, E G. O'Riordan, G Keane
IGC Proceedings (1977-2023)
The effect of closing dates (Experiment 1: August 1, August 14 and September 18) and grass regrowth interval (Experiment 2) on herbage yield in the autumn/winter and in the following spring were investigated on a previously grazed Lolium perenne sward. In Experiment 1, similar yields were obtained for the August 1 and August 14 closing. Yields decreased and the proportion of dead material increased from 0.19 to 0.61 between mid-October and late- December. In Experiment 2, dry matter yield increased linearly (P < 0.05) with rest interval up to 7 wks in swards closed in September. There was no significant yield advantage for rest intervals greater than 5-6 wks. It is concluded that accumulated autumn and spring yields showed increased DM production with the shorter regrowth intervals.

IGC Proceedings (1977-2023)
A grazing experiment was conducted in North-West Sardinia with the aim of testing the sward height as a mean to set up an efficient spring management of Italian ryegrass (Lolium multiflorum Lam.). Three fields were continuously grazed during spring 1992 by three groups of 12 dairy Sarda ewes, at three different sward heights (SH): 30 - 60 - 90 mm. The target sward height was obtained by continuously adjusting the field sizes. The results showed that the different grazing managements influenced the above ground biomass production and partitioning of the Italian ryegrass and the animal performances. During the vegetative …

Selective Sheep Grazing In An Heterogeneous Wheatgrass Dominated Pasture Related To Stocking Rate, G L. Siffredi, M A. Brizuela, M S. Cid, C Cangiano
IGC Proceedings (1977-2023)
It has been hypothesized that patch and community selection are driven by forage quality and/or quantity. We assess the relationship between vegetation characteristics and community and patch selection by sheep under continuous grazing at different stocking rates in an heterogeneous pasture. Our results suggest that when communities strongly differed in nutritive value sheep recurrently select the higher quality community in spite of its low biomass. However, sheep do not completely exclude the poorer quality community, generating a patchy vegetation pattern.

The Effect Of Slurry And Dirty Water Application To Swards On Grazing Behaviour In Dairy Cows, S Danby, J A. Laws, P D. Penning, B F. Pain, E Owen
IGC Proceedings (1977-2023)
In preference tests using pairs of turves in boxes (treated and control), dairy cows were more averse to surface spread than shallow injected slurry and more averse to slurry than dirty water. Effects of slurry persisted for up to 6 weeks, with fewer bites and less herbage removed from treated swards compared to control swards. Aversion to slurry may be decreased by injection. Effects of dirty water persisted for only 14 days.

Applications Of Height-Based Grazing Management In Mixed Swards, A Singh, J E. Johnston, E A. Clark
IGC Proceedings (1977-2023)
Grazing efficiency and livestock performance were compared on swards rotationally grazed down to either 50 or 100 mm for three years. With a fixed entry height of 200-250 mm, standing swards of mixed grasses and white clover (Trifolium repens L.) were stratified into 50 mm vertical layers both pre- and post-grazing. Through four or five cycles of grazing each year for three years, a fixed entry height range stabilized total standing herbage at 3250 to 3690 kg OM ha-1. Organic matter on-offer above 100 mm was 36, 45, and 43% of total standing herbage in the three years, compared …

Ingestive Behavior Of Fistulated And Intact Sheep Grazing Grass And Legumes Indoors And Outdoors, Y M. Gong, J Hodgson, M G. Lambert
IGC Proceedings (1977-2023)
Components of short-term ingestive behaviour were recorded for fistulated and intact sheep grazing turves in indoor crates, and for esophageal-fistulated sheep grazing swards in situ in outdoor cages. Perennial ryegrass, orchard grass and white clover at vegetative and reproductive growth stages were offered to the sheep. Bite weight, depth, area and volume did not differ between sheep grazing indoors and outdoors, nor between intact and fistulated sheep. Bite rate of fistulated sheep was slower indoors than outdoors (25.3 versus 32.1 bites/min), and intact sheep had a higher biting rate (36.7 versus 25.3 bites/min) than fistulated sheep. Bite weight was over-estimated …

Trace Mineral Status Of Beef Cattle Grazing Semiarid Rangelands Of North Mexico, J R. Kawas, G T. Armienta, E Olivares, O Torress, J J. Kawas, F Garza
IGC Proceedings (1977-2023)
Trace mineral concentrations of soil, forage and serum of range cattle of the northeast Mexico state of Nuevo Leon were determined in both wet and dry seasons of 1992. For each season, collections were made at twenty-four ranches within eleven counties of three regions. A total of 220 soil, 680 forage and 220 blood samples were collected and analyzed. No differences (P<0.05) between regions were obtained for Zinc (28.0 to 34.9 ppm) or Copper (4.4 to 5.4 ppm). Molybdenum concentrations were greater in the northern (2.1 ppm) than in the central (1.6 ppm) or southern (1.5 ppm) regions. Considering the critical levels in forages for Zinc (30 ppm) and Copper (10 ppm) reported by the National Research Council (1984), Zinc concentrations may be marginally deficient, whereas Copper concentrations were deficient in all three regions, in both seasons, and in grasses and woody species.

Influence Of Sheep And Goats On The Natural Succession, H D. Matthes, S Demise, M Schubert, H Mohring
IGC Proceedings (1977-2023)
A study was conducted to examine the effect of extensively-grazed pasture on the botanical composition. The trails were carried out in the year 1992 to 1995. For the study different breeds of sheep with the stocking rate of 30 sheep with their lambs / 2.6 ha were used. For the mixed-grazing a ratio of 20 sheep and 10 goats with their lambs / 2.6 ha were used. It is not possible to control all problem species with the help of sheepgrazing only. In contrast to that, it was concluded that goats grazed off all problem species quite effectively. Botanical composition …

Influence Of Different Breeds Of Pigs To The Natural Succession, H D. Matthes, A.C D. Micklich, G Dietl, H Mohring, W Jentsch
IGC Proceedings (1977-2023)
The aim of this study was to find out the effect of pigs on the natural succession. We used 4 different breeds of pigs for our investigations. Because of the grazing behaviour and their rooting activity the total number of plants increased up to 30%. But the vegetation quickly returned to conditions prior to rooting, if the rooting activity fails to happen. Rooting activity of pigs on floodplain soil and following grazing in the next spring after rooting permits seeds of different species of plants to germinate and develop in the plant free areas. These plants often have little chance …
