Methane Emissions Of Dairy Cows In Irish Spring-Calving, Grass Based Production Systems, Frank O'Mara, D. K. Lovett Jun 2023

Methane Emissions Of Dairy Cows In Irish Spring-Calving, Grass Based Production Systems, Frank O'Mara, D. K. Lovett

IGC Proceedings (1977-2023)

Countries which sign up to the Kyoto Protocol on greenhouse gas emissions are required to return annual inventories of greenhouse gas emissions, including methane emissions from farm livestock. Countries with large agricultural emissions are encouraged to derive specific emission factors (annual production of methane per animal in a specified animal class) for their livestock populations, rather than relying on default emission factors provided by IPCC (1996). In this paper, we describe how an emission rate of methane from enteric fermentation for spring-calving dairy cows in Irish production systems has been derived.

Rainfall And Grazing Impacts On The Population Dynamics Of Bothriochloa Ewartiana In Tropical Australia, David M. Orr, Peter J. O'Reagain Jun 2023

Rainfall And Grazing Impacts On The Population Dynamics Of Bothriochloa Ewartiana In Tropical Australia, David M. Orr, Peter J. O'Reagain

IGC Proceedings (1977-2023)

Bothriochloa ewartiana (desert bluegrass) is a palatable, native perennial (C4) grass of considerable importance to the northern Australian grazing industry. However, little is known of the interaction between grazing pressure and the highly variable rainfall found in this area, on its population dynamics. This paper reports interim results (1998-2004) from a long-term study, in which its population dynamics were examined under 3 grazing strategies.

Root And Vigor Response Of Big Bluestem To Summer Grazing Strategies, E. M. Mousel, W. H. Schacht, L. E. Moser, C. W. Zanner Jun 2023

Root And Vigor Response Of Big Bluestem To Summer Grazing Strategies, E. M. Mousel, W. H. Schacht, L. E. Moser, C. W. Zanner

IGC Proceedings (1977-2023)

Warm-season grasses e.g., big bluestem (Andropogon gerardii Vitman) are great potential sources of summer forage in eastern Nebraska. Frequent, intensive defoliation can reduce root mass and limit root distribution. Quantifying root structure response to multiple defoliation events in a grazing situation is critical to develop management plans for these types of grasses. This experiment aimed to quantify the cumulative effects of timing and frequency of grazing on root structure and organic reserve estimates in big bluestem pastures.

Effect Of Grazing Management On Herbage Accumulation Of Lucerne-Orchard Grass Sward, A. Hernández Garay, José L. Zaragoza Ramírez, J. Pérez-Pérez, S. González-Muñoz, J. Herrera-Haro, G. F. Osnaya, Pedro A. Martínez-Hernández, Adrián R. Quero-Carrillo, J. F. Enriquez-Quiroz

IGC Proceedings (1977-2023)

Throughout most of México, lucerne (Medicago sativa) is the primary forage legume used in the dairy industry. Unfortunately, lucerne does not grow in late autumn and winter due to adverse weather. Recent studies with lucerne have suggested that the inclusion of a companion grass will invariably increase the seasonal distribution and total annual yield of swards (Laidlaw & Teuber, 2001). However the management of mixed swards containing lucerne is difficult as a grazing frequency or intensity which suits one species may be detrimental to the other. Changes in balance between grass and legume, especially in grazed swards, have …

Tiller Population Density And Sward Stability Of Brachiaria Brizantha Continuously Stocked By Cattle, André F. Sbrissia, S. C. Da Silva, L. K. Molan, D. O. L. Sarmento, F. M. E. Andrade, A. V. Lupinacci, A. C. Gonçalves Jun 2023

Tiller Population Density And Sward Stability Of Brachiaria Brizantha Continuously Stocked By Cattle, André F. Sbrissia, S. C. Da Silva, L. K. Molan, D. O. L. Sarmento, F. M. E. Andrade, A. V. Lupinacci, A. C. Gonçalves

IGC Proceedings (1977-2023)

Tiller population density is one the most important parameters of sward structure and its evaluation is normally included in studies of sward dynamics. Moreover, a greater level of understanding is achieved when the survival of successive tiller generations is monitored. (Matthew et al., 2000). This would help to explain seasonal variation in tiller populations based on tiller appearance and death rates. While Brachiaria brizantha c.v. Marandu occupies up to 70 million hectares of cultivated grassland in Brazil, little is known of its ecophysiology. The objective of this work was to calculate survival probability of B. brizantha tillers and …

Managing The Reproductive Development Of Grasses By Grazing Practices, J. P. Theau, L. Chazelas, P. Ansquer, J. Viegas, O. Stefanini, M. L. Petit, P. Cruz, Michael Duru

IGC Proceedings (1977-2023)

Grazing natural grassland communities is necessary for both productive (feeding herbivores) and environmental (maintenance of open landscapes) objectives. Management guidelines should take into account the functional diversity of plant species between and within grassland communities. The management of the heading stage of grasses by grazing is an important tool to maintain acceptable forage quality and to avoid the seeding of low-valued species. The heading stage should be managed even in extensive systems and this needs a good knowledge of the phenological development of dominant species. In this work we illustrate the approach through the study of the development of four …

The Diet Of Free-Ranging Beef Cattle In A Semi-Arid Savanna Of Eastern Namibia, A. Rothauge, A. L. Abate, G. N. Smit Jun 2023

The Diet Of Free-Ranging Beef Cattle In A Semi-Arid Savanna Of Eastern Namibia, A. Rothauge, A. L. Abate, G. N. Smit

IGC Proceedings (1977-2023)

Beef ranching is the most important agricultural enterprise in arid and semi-arid SW African countries. It earns foreign exchange via beef exports to the EU and very many rural people depend on cattle pastoralism for their livelihood. However there is no published information on what cattle eat in such extensive systems. Therefore, it is difficult to optimize grazing strategies and to prevent degradation of rangeland.

Performance Of Timothy Cultivars In Monoculture Or In Mixtures With Meadow Fescue In Finland, M. Kari, M. Rinne Jun 2023

Performance Of Timothy Cultivars In Monoculture Or In Mixtures With Meadow Fescue In Finland, M. Kari, M. Rinne

IGC Proceedings (1977-2023)

Timothy (Phleum pratense) and meadow fescue (Festuca pratensis) are dominating grass species in Nordic countries with severe winters. Dry matter (DM) yield potential, forage quality and winter hardiness are of main interest for commercial cultivars. Further, it is advantageous to take into account the relation between primary growth and regrowth (P/R) DM yield when planning mixtures for different purposes and areas. In the current experiment, three different types of timothy were evaluated: a northern type cv. Jonatan, a southern type cv. Ragnar and an intermediate type cv. Grindstad. In addition, meadow fescue cv. Kasper and mixtures …

Effect Of Dairy Effluent On Turnip Nutritive Characteristics, Joe L. Jacobs, G. N. Ward, Frank R. Mckenzie Jun 2023

Effect Of Dairy Effluent On Turnip Nutritive Characteristics, Joe L. Jacobs, G. N. Ward, Frank R. Mckenzie

IGC Proceedings (1977-2023)

In southern Victoria, high summer temperatures and low rainfall lead to low pasture growth and a decline in nutritional value until rainfall commences in autumn. Annual forage crops such as turnips often are used to fill the summer feed gap. Jacobs & Ward (2003) observed that dairy effluent applied at low rates could improve turnip DM yields and crude protein content. Results from the first two years of a 3-year study comparing a range of effluent application rates on turnip leaf and root nutritive characteristics are reported.

Effects Of Grass Suppression On Legume Abundance In A Naturalised Pasture, Christian Hepp, I. Valentine, P. D. Kemp Jun 2023

Effects Of Grass Suppression On Legume Abundance In A Naturalised Pasture, Christian Hepp, I. Valentine, P. D. Kemp

IGC Proceedings (1977-2023)

Low abundance and poor persistence of legumes is a generalised problem in hill country pastures in New Zealand, even at adequate soil phosphorus levels (Woodfield & Caradus, 1996). Likely causes of low legume contents in swards include lack of soil moisture, high temperatures (Barker et al., 1993), frequency and intensity of defoliation (Suckling, 1975; (Lambert et al., 1982) and increased grass competition due to increasing fixed nitrogen in the soil (Lambert et al., 1982). On this later point there is anecdotal evidence that suppression of the grass component with herbicide will boost clover content, colloquially called 'chemical topping'.

Butterfly Pea In Queensland: A Tropical Forage Legume Success Story, Maurice J. Conway Jun 2023

Butterfly Pea In Queensland: A Tropical Forage Legume Success Story, Maurice J. Conway

IGC Proceedings (1977-2023)

Butterfly pea (Clitoria ternatea) is a productive and persistent legume adapted to a range of soils and climates in northern (tropical & sub tropical) Australia. Cultivar Milgarra, a composite line of introduced and naturalised accessions, was released in Queensland in 1991. The area planted in Queensland is a measure of its success, reaching <500ha in 1996; 5Kha by 1998; 30Kha by 2000; 50Kha by 2002; and 100Kha by 2004. Butterfly pea is used by cattleman mostly to grow and finish cattle. It is not grown extensively as a ley legume yet. Farmers who crop and have cattle, plant it but usually on cropping soils with limitations e.g. low plant available water capacity, shallow, low N or duplex soils. Farmers without cattle generally choose to use inorganic nitrogen as an N-source for crops.

Forage Peanut (Arachis Pintoi): A High Yielding And High Quality Tropical Legume For Sustainable Cattle Production Systems In The Western Brazilian Amazon, Judson F. Valentim, C. M. S. De Andrade

IGC Proceedings (1977-2023)

The State of Acre had 1.45 million ha of pastures and a cattle herd of 1.95 million heads in 2003. Since 1998, the increasing area affected by the death of Marandu grass (Brachiaria brizantha) led farmers in Acre to search for alternatives to maintain productivity and profitability of their production systems. However, the traditional strategy of converting primary forest areas into pastures has been severely restricted by strong enforcement of environmental legislation by state and federal agencies. This forced farmers to search for alternative technologies to reclaim degraded pastures and to intensify their production systems. Tropical kudzu ( …

Tropical Kudzu (Pueraria Phaseoloides): Successful Adoption In Sustainable Cattle Production Systems In The Western Brazilian Amazon, Judson F. Valentim, C. M. S. De Andrade

IGC Proceedings (1977-2023)

In 1976 the Program for Reclamation, Improvement and Management of Pastures in the Brazilian Amazon (PROPASTO), conducted by Embrapa, established on-farm experiments in the State of Acre. These experiments consisted of introducing and evaluating grass and grass-legume stands, both under cutting and grazing. Similar experiments were established in all states in the region. Since then, research has recommended new species of grasses, legumes and grass-legume associations for establishment of improved pastures in the Brazilian Amazon. The grass cultivars recommended were an instant success with farmers, with Brachiaria brizantha cv. Marandu becoming the predominant species, occupying approximately 80% of the total …

Arachis Pintoi In The Humid Tropics Of Colombia: A Forage Legume Success Story, E. Lascano Carlos, M. Peters, F. Holmann

IGC Proceedings (1977-2023)

Cattle liveweight gain and milk yield can be depressed significantly on grass alone pastures that degrade over time on the margins of tropical forest. Use of legumes in pastures is an alternative to minimize declines in quality and quantity of forage biomass and thus increase livestock production. From 1987-90, forage researchers in CIAT collaborated with several institutions in the Piedmont region of the Amazon basin in Caqueta, Colombia on selection of forage germplasm adapted to acid soils and with potential to reclaim large areas of degraded pastures in cattle farms of the region. The most successful pasture was the legume/ …

Centrosema Pascuorum In Australia’S Northern Territory: A Tropical Forage Legume Success Story, A. G. Cameron Jun 2023

Centrosema Pascuorum In Australia’S Northern Territory: A Tropical Forage Legume Success Story, A. G. Cameron

IGC Proceedings (1977-2023)

Centurion (Centrosema pascuorum), an annual legume, was first sown for evaluation in the Northern Territory in the late 1970s (Cameron & McCosker, 1986; Clements et al.,1984). The bred cultivar Cavalcade (Line 2/2, Cameron, 2003b) was released in 1984, and Bundey (CPI 75115, Cameron, 2003a) in 1986. Seed availability limited the use of the legume for 10 years. In the Northern Territory, it is now used mainly as a hay crop, but is used also as a component of grazed mixed pastures. Most of the hay is made into feed cubes and pellets to feed cattle in the …

Leucaena: Sustainable Crop And Livestock Production Systems In Nusa Tenggara Timur Province, Indonesia, C. Piggin, Jacob Nulik Jun 2023

Leucaena: Sustainable Crop And Livestock Production Systems In Nusa Tenggara Timur Province, Indonesia, C. Piggin, Jacob Nulik

IGC Proceedings (1977-2023)

In the late 1800s/early 1900s, population increases, slash and burn cropping, wildfires, livestock, and weeds led to extensive losses of natural vegetation and land degradation in the semi-arid islands of Nusa Tenggara Timur province, E Indonesia. In the 1930s-60s, villagers, government institutions and NGOs recognized the need to reduce degradation and increase production. They developed and promoted more sustainable fallow systems, based on the use of leucaena (Leucaena leucocephala), introduced several centuries earlier from central America.

Sesbania Grandiflora: A Successful Tree Legume In Lombok, Indonesia, D. Hasniati, M. Shelton

IGC Proceedings (1977-2023)

Sesbania (Sesbania grandiflora) is a multi-function tree. Its main use is as a livestock feed in southern Lombok, Indonesia, the major region for goat and cattle production. It is the main (and sometimes the only) component of ruminant diets (Dahlanuddin, 2001). A national program, aimed initially at improving soil fertility and replanting barren areas, formally introduced it to Lombok in the 1970s (Suseno, 1990).

Stylo Adoption In Thailand: Three Decades Of Progress, Chaisang Phaikaew, Michael D. Hare Jun 2023

Stylo Adoption In Thailand: Three Decades Of Progress, Chaisang Phaikaew, Michael D. Hare

IGC Proceedings (1977-2023)

Stylosanthes forage legume was very popular in Thailand for >30 years. S. humilis (Townsville) was the first popular species (late 1960s). It tolerated heavy grazing and grew very well along roads on free-draining upland soils, but anthracnose destroyed it in 1976. S. hamata (Verano; more resistant) replaced it and stimulated of large-scale pasture development. From 1976-84, the Dept of Livestock Development (DLD) launched a project to improve 32Kha of communal grazing land by oversowing Verano (circa 250t seed/year). This project has been sustained until the present time. Stylo now is used mainly for private grazing and cut-and-carry feeding for cattle. …

An In Vitro Investigation Of Forage Factors Which Affect The Production Of Conjugated Linoleic Acid And Trans Vaccenic Acid In The Rumen. I. Grass Species, Michael R. F. Lee, C. Hodgkins, J. K. S. Tweed, Nigel D. Scollan, R. J. Dewhurst Jun 2023

An In Vitro Investigation Of Forage Factors Which Affect The Production Of Conjugated Linoleic Acid And Trans Vaccenic Acid In The Rumen. I. Grass Species, Michael R. F. Lee, C. Hodgkins, J. K. S. Tweed, Nigel D. Scollan, R. J. Dewhurst

IGC Proceedings (1977-2023)

Extensive, pasture-based systems appear to offer the most cost-effective and natural means of cis 9 trans 11 conjugated linoleic acid (CLA) levels of milk fat. However, since most regions in Europe rely increasingly on conserved forages for winter feeding of lactating animals, it is necessary to develop feeding systems for both fresh and conserved forage diets. An understanding of the mechanisms that cause the differences in CLA response to conservation is an essential pre-requisite to this task. This study investigated whether grass species affected CLA and trans vaccenic acid (TVA) production in an in vitro system.

IGC Proceedings (1977-2023)

Grasses with high levels of WSC have been shown to enhance livestock production (Miller et al., 1999). This has led to the development of perennial ryegrass (PRG) cultivars that can accumulate high levels of WSC. The aim of this experiment was to determine if the genetic potential to accumulate high levels of WSC was expressed under varying conditions.

Selection For Tillering In Lolium Multiflorum L. In Texas Usa, L. R. Nelson, G. W. Evers, M. J. Parsons Jun 2023

Selection For Tillering In Lolium Multiflorum L. In Texas Usa, L. R. Nelson, G. W. Evers, M. J. Parsons

IGC Proceedings (1977-2023)

Annual ryegrass is an important cool season forage in Texas and across the southern USA with approximately 2 million ha planted annually. Early tillering will enhance the leaf area index and the amount of photosynthesis which will improve seedling vigor and early forage production. The objective of this study was to determine if it was possible to select for early tiller (shoot) production in a diploid and tetraploid annual ryegrass breeding population. We expect early tiller production would be correlated with improved early season forage production with annual ryegrass.

The Impact Of Continuous Grazing By Free Ranging Sheep On The Structure And Botanical Composition Of Grassland As Determined By Multivariate Analysis, G. A. Heshmati Jun 2023

The Impact Of Continuous Grazing By Free Ranging Sheep On The Structure And Botanical Composition Of Grassland As Determined By Multivariate Analysis, G. A. Heshmati

IGC Proceedings (1977-2023)

Grazing shapes the botanical composition of vegetation at the landscape level (Oksanen et al., 1995). Sheep seek spatially scattered plants of nearly constant and high nutritional value. There is strong interaction between the grazing behaviour of the sheep and the structure of the plant community that it grazes (Squires, 1981). This paper examines the situation in a grassland vegetation grazed by free-ranging sheep in a semi arid region of North Eastern Iran.

Sheep Grazing During Drought Collapses The Perennial Grass Resource In Australian Semiarid Wooded Grasslands, K. C. Hodgkinson, S. G. Marsden, W. J. Muller Jun 2023

Sheep Grazing During Drought Collapses The Perennial Grass Resource In Australian Semiarid Wooded Grasslands, K. C. Hodgkinson, S. G. Marsden, W. J. Muller

IGC Proceedings (1977-2023)

Grazing of sheep in arid grasslands is risky; sudden shifts to lower functional states may occur when the ecosystem is stressed (Scheffer et al., 2001). To avoid the stresses that shift states, easy-to-recognise critical thresholds need to be identified (Westoby et al., 1989). Preliminary analysis of perennial grass survival in a drought indicated a critical threshold based on co-occurrence of drought and grazing. Crossing this threshold collapses grass populations (Hodgkinson, 1994). Here we examine the relationships between basal area change and rainfall and grazing levels based on a 10-year period and propose a management guideline.

Impacts Of Strategic Grazing On Density And Ground Cover Of Naturalised Hill Pasture, Zhongnan Nie, P. E. Quigley, R. P. Zollinger Jun 2023

Impacts Of Strategic Grazing On Density And Ground Cover Of Naturalised Hill Pasture, Zhongnan Nie, P. E. Quigley, R. P. Zollinger

IGC Proceedings (1977-2023)

Low ground cover by perennial species is a major problem in naturalised pasture on steep hill country in southern Australia. This leads to water and nutrient runoff, recharge to groundwater, and soil erosion, all of which impact on the environmental sustainability and profitability of grazing enterprises. Restoration of perennial components, particularly the native grasses for these marginal land classes, is of great importance for improving water balance, halting land degradation (Ridley et al. 1997), extending growing season, and increasing pasture production. The objective of this study was to use strategic grazing management to increase the ground cover and plant …

Effects Of Vegetation Structure And Plant Height When Grazed On Persistency Of Meadow Fescue Pasture, K. Sudo, Y. Ogawa, K. Umemura Jun 2023

Effects Of Vegetation Structure And Plant Height When Grazed On Persistency Of Meadow Fescue Pasture, K. Sudo, Y. Ogawa, K. Umemura

IGC Proceedings (1977-2023)

An intensive grazing technique using meadow fescue (Mf) pasture has been developed in northern Japan, where soil freezes in winter. It has been shown that the appropriate plant height of Mf pasture when grazed for persistency is about 27 cm. When Mf and perennial ryegrass (Pr) pastures were grazed at the same plant height of 20 cm, vegetation of Mf pasture declined and plant length of Mf pasture was longer than that of Pr pasture (Sudo et al., 2002). These phenomena might be due to the effects of differences in grass species and plant height when grazed on vegetation …
