Water Use Efficiency In Chilean And Argentine Humid Temperate Grass-Legume Pastures, H G. Landi, M H. Wade, V Garcia De Cortazar, D E. Dalla Valle
IGC Proceedings (1997-2023)
At two sites in Argentina and Chile five levels of water input were applied to four sown pastures of varying ages during spring and summer. The pastures consisted principally of C3 grasses and legumes, some of which were sown such as Lolium perenne, Trifolium repens, Dactylis glomerata. Dry matter (DM) production was measured and related to the estimated total evapotranspiration (ET): responses were both highly linear. Both responses to ET and absolute yields were higher at the Argentinian than at the Chilean site: respectively 10.7 and 15.2 kg DM/mm water evapotranspired. Nevertheless the calculated indices of sensitivity (Ky) of Doorenbos …

Contribute To A Definition Of Extensive Grazing (Mediterranean), J. Potes, J. P. F. Almeida, C. Matos, A. Teixeira
IGC Proceedings (1997-2023)
The subject of this paper is a definition of Extensive Grazing from Extensive Systems of Animal Production in Mediterranean environments. The edaphoclimatic characterization is essential to understand the low level of primary productivity as a consequence of irregular precipitation over the year and its absence during the long, dry and hot summer. The powerless of soils justify the limited contribution of plants and make clear the necessary recovery of the soil and storage of water naturally (soil) or artificially (irrigation). Considering the IPBES (Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services) definition of extensive grazing it has been used the …

IGC Proceedings (1997-2023)
This paper reviews the distribution and importance of annual clover (Trifolium) species for pasture and fodder production systems globally. Of the 158 recorded annual Trifolium species, 65.2% are endemic to the Mediterranean basin and surrounding areas, 14.6% to sub-Saharan Africa, 17.7% to the United States of America and 2.5% to Chile. Fourteen species have been commercialised, while other endemic and naturalised annual clovers are also utilised. Key species for self-regenerating pastures include T. subterraneum, T. michelianum and T. respinatum var. resupinatum, while major dual-purpose grazing and fodder species include T. incarnatum, T. vesiculosum, T. alexandrinum and T. …
Impact Of Brown Midrib Trait On The Decomposition Rate Of Sorghum-Sudangrass Residue In Pastures, C. D. Teutsch, B. P. Dooley, J. A. Bush, B. L. Hendrix
Impact Of Brown Midrib Trait On The Decomposition Rate Of Sorghum-Sudangrass Residue In Pastures, C. D. Teutsch, B. P. Dooley, J. A. Bush, B. L. Hendrix
IGC Proceedings (1997-2023)
Sorghum-sudangrass (Sorghum bicolor var. bicolor x bicolor var. sudanense) can provide high quality summer grazing. Some varieties possess the brown midrib (BMR) trait which results in reduced lignin resulting in higher digestibility and animal performance. If microbes in the rumen can digest BMR sorghum-sudangrass more completely, then soil macro/micro flora and fauna may do so as well. This could result in nutrients being returned to the soil faster from plants containing the BMR trait. The objective of this study was to determine the decomposition rate of BMR and non-BMR sorghumsudangrass. The experimental design was a random complete with four …
Forage And Livestock Productivity On Pastures Of Differing Plant Diversity, B. F. Tracy
Forage And Livestock Productivity On Pastures Of Differing Plant Diversity, B. F. Tracy
IGC Proceedings (1997-2023)
Plant diversity and its function in grassland ecosystems has been the focus of many recent studies, and debate, in the ecological literature (Wardle 1999, Loreau and Hector 2001). We know less about the role of plant diversity in pastures used solely for agricultural production (Sanderson et al. 2004). The objective of this study was to learn how pastures planted with increasing levels of plant diversity would affect forage yields and beef cattle performance.

Balancing Water Use Efficiency And Milk Production In The Sub-Tropics, Mark N. Callow, S. K. Kenman
IGC Proceedings (1997-2023)
Queensland dairy farmers have had to confront in the last 5 years deregulation of the milk pricing system, resulting in a 25% reduction in farm gate price for milk in the year 2000, and drought. Many storage dams are significantly below capacity and regulatory authorities have imposed restrictions on irrigation water allocations. Major changes in farm business strategies were needed to overcome the shortfall in milk income. Production systems had to change to deliver more milk more efficiently and become more profitable. A farmlet study was developed in the sub-tropical dairy region of Queensland to evaluate 5 very different farm …
Sustainable Pastures For The High Altitude Andean Tropics Of Colombia, E. Cárdenas, L. Panizzo
Sustainable Pastures For The High Altitude Andean Tropics Of Colombia, E. Cárdenas, L. Panizzo
IGC Proceedings (1997-2023)
Dairy production systems in the high altitude Andean region of Colombia (>2.600 m.a.s.l.) use large amounts of nitrogen (N) fertilisation. Due to the inefficient use of N by the grass, it contaminates surface and ground water resulting in the eutrophication of lakes and rivers. It contributes to increased atmospheric NOx, greenhouse gas and acid rain. Therefore, the effect of different species of grasses mixed with Lotus corniculatuson N soil balance was evaluated.

Portuguese Society Of Pastures And Forages, J. Potes, E. V. Lourenço, T. Carita
IGC Proceedings (1997-2023)
The Portuguese Society of Pastures and Forages (SPPF) was born from a course on pastures and forages held in the National Plant Breeding Station of Elvas (where the headquarters of SPPF are located) in 1979. It was organised by the head of the Pastures and Forages Department, David Gomes Crespo, who was the first and founder member. According to Abreu et al. (1999), the structure established was that of a Scientific Society and was considered by the Government as a Service of Public Interest. It gathered inspiration from the British Grassland Society, the Association Francaise pour la Production Fourragére, …
Dormant-Season Carbon Fluxes In Humid-Temperate Pastures, Howard Skinner
Dormant-Season Carbon Fluxes In Humid-Temperate Pastures, Howard Skinner
IGC Proceedings (1997-2023)
Human induced increases in atmospheric CO2 through the burning of fossil fuels and deforestation are considered to be a primary cause of rising global temperatures. However, carbon sequestration by terrestrial ecosystems has reduced the rate of CO2 accumulation in the atmosphere. Because of their vast size, grazing lands have the potential to sequester significant quantities of carbon, slowing the increase in atmospheric CO2 and reducing the risk of global warming. Although C uptake during the growing season can be substantial, losses following defoliation and drought, and during the winter months can significantly reduce annual sequestration, frequently turning …
A Sward Based Method To Estimate Herbage Selection Of Grazing Dairy Cows, F. Taube, M. Wachendorf, J. Baade
A Sward Based Method To Estimate Herbage Selection Of Grazing Dairy Cows, F. Taube, M. Wachendorf, J. Baade
IGC Proceedings (1997-2023)
Diet selection of grazing animals is influenced by sward composition and vertical sward structure. Grazing studies were established in northern Germany (Kiel, Schleswig - Holstein state) to determine if selective grazing behaviour in a mixed sward can be measured by a sward based method. The hypothesis that active selection of different functional groups of forages can be documented by using the selection index (Figure 1, Hodgson, 1990) and regressive approaches vs time was tested.

IGC Proceedings (1997-2023)
Producing animals without using feed-grade antibiotic growth promoters and chemical medicines is essential. In response, many scientists are now studying medicinal plants and herbs to identify and quantify those plants that may have a beneficial effect on animal production. Plantains have been used in herbal medicines and are being evaluated as a potential pasture species because of their medicinal values in animal health. In this study, antioxidant activities of plantains were compared to those of common pasture species to clarify the effects of plantains on animal health and production.

Characterisation Of Herbage From Temperate Organic Pastures, E. Kuusela
IGC Proceedings (1997-2023)
Grazing is an essential part of organic dairy farming systems. Although the nutritive value of herbage and herbage availability determine the intake and nutrient supply for grazing cows, the composition of typical herbage from organic pastures has been unclear.
Intake And Milk Production Of Lactating Dairy Cows Grazing Diverse Forage Mixtures Over Two Grazing Seasons, K. Soder, M. A. Sanderson, J. L. Stack, L. Muller
Intake And Milk Production Of Lactating Dairy Cows Grazing Diverse Forage Mixtures Over Two Grazing Seasons, K. Soder, M. A. Sanderson, J. L. Stack, L. Muller
IGC Proceedings (1997-2023)
Voluntary intake and stocking rate are key determinants of animal performance on pasture. Greater plant diversity in grassland plant communities has been linked to increased primary production, greater stability in response to disturbance, and reduced weed pressure. Thus, increasing plant diversity may be one approach to improving animal productivity. An experiment was conducted to determine the effects of forage diversity on intake and milk production of lactating dairy cows over two grazing seasons.

IGC Proceedings (1997-2023)
Managing complex mixtures of plants to take advantage of spatial and temporal variability in land and climate may be one ecological approach to increase productivity of pastures. We tested the hypothesis that complex mixtures of forage species would yield more herbage and reduce weed competition compared with a simple grass-legume mixture in grazed pastures.

Evaluation Of Cool-Season Annuals Effect On Soil Health In Warm-Season Perennial Pastures In Southestern Us., Paola C. Muela Negrete
LSU Master's Theses
Perennial grass crops represent approximately 8 million hectares of the land area of the humid lower southeastern United States. These forage crops receive high rates of fertilizer, especially nitrogen (N), and near monoculture remains have often been treated with repeated applications of herbicides. Pasture management is crucial to improve soil properties in pasturelands. Common pasture management practices include introducing cool-season multispecies in warm-season pasture systems and forage harvest frequency of pasture systems. It is known that cool-season multispecies in warm-season pasture systems ensure cattle feeding during winter season and have beneficial effects on soil microbial biomass, soil organic matter (SOM), …
History Of Grass Breeding For Grazing Lands In The Northern Great Plains Of The Usa And Canada, Kenneth P. Vogel, John Hendrickson
History Of Grass Breeding For Grazing Lands In The Northern Great Plains Of The Usa And Canada, Kenneth P. Vogel, John Hendrickson
Department of Agronomy and Horticulture: Faculty Publications
• In the early 1930s there were millions of acres of extensively degraded grazing lands and abandoned and eroded cropland in the Northern Plains of the United States and Canada.
• Grass breeding and plant materials programs were established by both the US and Canadian governments and cooperating universities to develop revegetation materials.
• Efforts of a small number of research locations and people resulted in grass cultivars or varieties that were used to revegetate and preserve the soil on millions of acres of land.
• This is a brief history of the people, agencies, and universities that developed these …

Including Legumes In Bermudagrass Pastures, J. L. Moyer, L. W. Lomas
Kansas Agricultural Experiment Station Research Reports
Use of legumes in bermudagrass pastures has often increased summer cow gains. Forage production was greater where ladino clover was used in the Legume system than where Nitrogen (N) alone was used in the first sampling, but the reverse was true in midsummer. Estimated forage crude protein during 2015 was greater for the Legume than the Nitrogen system in the first and last samplings, but similar in mid-summer pasture. Cow performance over the season was increased 68% where legumes were used.

Tree Windbreaks In The Wheatbelt, Robert Sudmeyer, David Bicknell, Neil Coles
Tree Windbreaks In The Wheatbelt, Robert Sudmeyer, David Bicknell, Neil Coles
Bulletins 4000 -
Windbreaks comprising trees, or tree and shrub combinations, can offer many benefits on wheatbelt farms, particularly for protection of soil, stock, crops and pastures from damaging winds and erosion. Additional benefits include reduced evaporation from farm dams, reduced groundwater recharge, their use as nature conservation corridors and habitats, increased biodiversity including predators of crop and pasture pests, fire control, tree products and improved lifestyle and aesthetics.
In other areas and farming systems such as intensive horticulture, man-made windbreaks may be used, but their higher cost makes them unsuited for broadscale agriculture. Man-made windbreaks can be effective in reducing evaporative losses …
