Assessment And Improvement Of The Efficiency Of Nitrogen Use On Commercial Dairy Farms, D. J. Roberts, K. A. Leach, J. Goldie Aug 2023

Assessment And Improvement Of The Efficiency Of Nitrogen Use On Commercial Dairy Farms, D. J. Roberts, K. A. Leach, J. Goldie

IGC Proceedings (1977-2023)

Dairy farming systems have a low efficiency of converting nitrogen (N) into milk protein, due to the many transfers which occur in the production process. Losses of N from the system can be detrimental to the environment and represent wasted inputs. At SAC, in a systems research project, management changes achieved increases in nitrogen efficiency (milk N output/ N inputs) (NE) from 23 to 34% in a grass-clover based system (GC), and 13 to 21% in a purchased fertiliser based system (GN) (Leach & Roberts, 2002). Nitrogen surplus (NS = N inputs - N output in sold produce) was reduced …

On-Farm Participatory Research Is An Essential Step Towards Achieving Successful Adoption Of Innovation: ‘Lifetime Wool’ A Case Study, Chris Oldham, P. Barber, M. Curnow, S. Giles, D. Gordon, A. Thompson Aug 2023

On-Farm Participatory Research Is An Essential Step Towards Achieving Successful Adoption Of Innovation: ‘Lifetime Wool’ A Case Study, Chris Oldham, P. Barber, M. Curnow, S. Giles, D. Gordon, A. Thompson

IGC Proceedings (1977-2023)

'Lifetime Wool' project (LTW) is a national project that is developing new nutritional guidelines for the management of ewe flocks across Australia funded by farmers through Australian Wool Innovation (AWI EC298; 2001-2008). A large replicated plot-scale experiment was used to define the dose-response of current production (wool and reproduction from the ewe) and future production (survival, growth and wool from progeny over their lifetime) to a range of levels of ewe nutrition (Thompson & Oldham, 2004). However, farmers and research workers have long realised that the difference between the results obtained on experimental plots and those obtained by farmers is …

Farmer-Driven Research For Developing Models Of Successful Low Input Dairy Farms Of Small To Medium Size In The American Midwest, D. G. Johnson, M. V. Rudstrom, R. Imdieke, E. Ballinger, G. J. Cuomo Aug 2023

Farmer-Driven Research For Developing Models Of Successful Low Input Dairy Farms Of Small To Medium Size In The American Midwest, D. G. Johnson, M. V. Rudstrom, R. Imdieke, E. Ballinger, G. J. Cuomo

IGC Proceedings (1977-2023)

The dairy industry in the upper Midwest continues to evolve with a drastic reduction in the number of dairy farms with less than 100 cows that utilise tie-stall housing. Many of the farms that do remain are at a critical point where facilities require renovation or replacement that is not economic. Rural communities have fewer residents engaged in agriculture to participate in the local economy and the rural landscape includes many farm sites that are abandoned. Low input dairies are an alternative system developed by farmers as a grass-roots movement. Low input farms may include grazing, outdoor housing throughout the …

Management Of Gastro-Intestinal Parasite Pressure, Under Grazing In Organic Farms: Development Of A Decision Support System Through The Mobilisation Of A Participative Research Process, D. Jamar, Virginie Decruyenaere, Y. Seutin, D. Stilmant, L. Perriaux, P. Stassart Aug 2023

Management Of Gastro-Intestinal Parasite Pressure, Under Grazing In Organic Farms: Development Of A Decision Support System Through The Mobilisation Of A Participative Research Process, D. Jamar, Virginie Decruyenaere, Y. Seutin, D. Stilmant, L. Perriaux, P. Stassart

IGC Proceedings (1977-2023)

Under grazing, gastro-intestinal parasite management remains a major problem in ruminant production systems, more especially in systems respecting organic farming rules following their obligations (1) to perform grazing as soon as pedo-climatic conditions are adapted and (2) to use anti-parasitic products only in a curative way. Surprisingly, this problem has not been highlighted by the different stakeholders in the food chain from cattle meat production to consumption. This could arise from the lack of a clear and pertinent norm or infestation threshold that would allow differentiation between preventive and curative treatments. Such a norm would indicate to the breeder whether …

Organic Herbage Seed Production In Wales - Working With Farmers To Develop The Technology, H. Mccalman, A. M. Marshall Aug 2023

Organic Herbage Seed Production In Wales - Working With Farmers To Develop The Technology, H. Mccalman, A. M. Marshall

IGC Proceedings (1977-2023)

The National Assembly Government of Wales is providing incentives for organic farming through its agri -environment schemes and has set a target of 10% by 2010. The organic systems in Wales are grassland based, including some with crop rotations and grass-clover leys. Reseeding currently relies on 60% conventional seed, but this derogation to the organic standard of 100% will be removed by August 2005. Conventional methods of seed production are not acceptable under organic standards. Following farmer discussion group meetings highlighting the difficulty of sourcing and the cost of organic seed, a feasibility project to tackle some of the practical …

Farmer Adoption; Ten Years Of Productive Pasture Systems In Southern Australia, Geoffrey Saul, H. L. Quinn, J. T. Trompf Aug 2023

Farmer Adoption; Ten Years Of Productive Pasture Systems In Southern Australia, Geoffrey Saul, H. L. Quinn, J. T. Trompf

IGC Proceedings (1977-2023)

n Southern Australian sheep and beef farmers have been slow to adopt technology related to grazing management and pasture utilisation despite clear evidence of a strong link between utilisation (stock per ha) and profitability. Between 1971-95, the average stocking rate on farms was 10-12 dry sheep equivalent per hectare (dse/ha) (Anon 2004). Results from the Hamilton Long-term Phosphate Experiment (Cayley et al., 2002) show higher pasture production, herbage digestibility, stocking rates and profitability as phosphorus fertiliser applications increase. In 1993, the Grassland Productivity Program (GPP) started in the winter rainfall areas of southern Australia (Trompf & Sale 2000), initiated …

Participatory Development Of A Forage Grass Cultivar, Michael D. Casler, P. G. Pitts, P. C. Bilkey, C. A. Rose-Fricker Aug 2023

Participatory Development Of A Forage Grass Cultivar, Michael D. Casler, P. G. Pitts, P. C. Bilkey, C. A. Rose-Fricker

IGC Proceedings (1977-2023)

Perennial forage grasses exist in both nature and agriculture as a highly heterogeneous mixture of genotypes. Extreme environments, fluctuating environments, and severe managements can impose selection pressures that will result in loss of unadapted genotypes. Mortality of unadapted genotypes leads to dominance of fewer highly adapted genotypes which may be useful as superior germplasm in other similar environments.

Livestock Producers And Researchers - A Case Study Of An Effective Partnership, R. D. B. Whalley, I. H. Simpson, W. K. Mason Aug 2023

Livestock Producers And Researchers - A Case Study Of An Effective Partnership, R. D. B. Whalley, I. H. Simpson, W. K. Mason

IGC Proceedings (1977-2023)

The Sustainable Grazing Systems Programme (SGS) ran from 1996-2002 with 11 regional producer committees (Regional Producer Network - Simpson et al., 2003) and 6 research sites (National Experiment Andrew & Lodge, 2003) distributed throughout the high rainfall zone of temperate Australia. Each regional committee had a core of producers, with invited scientists and extension practitioners and a paid facilitator. The chair was always a producer and rotated annually. Each regional committee conducted a number of paddock-sized demonstrations of improved grazing management practices on a number of farms within the themes; grazing management and weeds, high input systems, innovative grazing …

Adoption Of Participatory Rural Appraisal: A Case Study From China, A. Chu, A. D. Meister, P. Guo, J. Reid, B. Nowak, S. Morris, John Hodgson, P. N. P. Matthews, P. Gregg, K. Cai, J. Xie, X. Y. Li Aug 2023

Adoption Of Participatory Rural Appraisal: A Case Study From China, A. Chu, A. D. Meister, P. Guo, J. Reid, B. Nowak, S. Morris, John Hodgson, P. N. P. Matthews, P. Gregg, K. Cai, J. Xie, X. Y. Li

IGC Proceedings (1977-2023)

There are many models of technology transfer. They vary from the linear "scientist-extension worker-farmers" model to the integrative "natural resource management" model (Jiggins, 1993). International experience has shown that for small holding farmers in developing countries a farmer driven model based on participatory approaches (the Participatory Rural Appraisal (PRA) Model) is more effective and efficient.

On-Farm Research To Improve The Measure Of Variability Of Forage Production Across The Landscape For Evaluating Economic Risk In Forage-Based Enterprises, Ed B. Rayburn Aug 2023

On-Farm Research To Improve The Measure Of Variability Of Forage Production Across The Landscape For Evaluating Economic Risk In Forage-Based Enterprises, Ed B. Rayburn

IGC Proceedings (1977-2023)

Experiment station trials provide forage crop mean yields and standard deviations (SD) useful in evaluating risk in forage production (Rayburn, 2003). However, in the northeast USA many of these sites are on valley soils atypical of hill-farms in the Appalachian Mountains. This study used on-farm and experiment station research to evaluate the variability of forage yield across a range of soils. This information was used in stochastic budgets to evaluate the economic risks in forage production on soils differing in yield potential.

Leygrain: A Participatory Action-Learning Model For Ley Pastures In Cropping Systems, D. L. Lloyd, B. Johnson, S. M. O'Brien Aug 2023

Leygrain: A Participatory Action-Learning Model For Ley Pastures In Cropping Systems, D. L. Lloyd, B. Johnson, S. M. O'Brien

IGC Proceedings (1977-2023)

Since the 1930s, crop/pasture rotation systems have been used in the wheat-sheep belt of temperate southern Australia to maintain the productivity and environmental sustainability of farming systems (Puckridge & French, 1983). Yet, in the northern grain belt of Australia, there is limited adoption of ley pastures, owing to inherently fertile and well-structured vertisol soils. However, soil fertility decline now costs the grain industry about $450 m per year. Legume-based leys are an option for improving soil OM and N and providing other benefits to cropping and livestock production systems (Lloyd et al., 1991). Despite strong one-on-one extension processes since …

Farmer-Directed On-Farm Experimentation Examining The Impact Of Companion Planting Barley And Oats On Timothy-Lucerne Forage Establishment In Central Newfoundland, D. Spaner, A. G. Todd Aug 2023

Farmer-Directed On-Farm Experimentation Examining The Impact Of Companion Planting Barley And Oats On Timothy-Lucerne Forage Establishment In Central Newfoundland, D. Spaner, A. G. Todd

IGC Proceedings (1977-2023)

Growing barley or oats in the year of forage establishment is a common agronomic practice in marginal growing regions, but is often not recommended to growers in Newfoundland. Spaner & Todd (2003) reported that barley seeded at rates of 100-150 kg seed/ha and undersown with a timothy-clover mixture (harvested at mid-milk) resulted in the planting year in greater forage yield of poorer quality than pure-stand timothy-clover. A barley seeding rate of 100 kg seed/ha did not impede forage production in the subsequent year.

Use Of Forage Legumes To Restore Overgrazed Natural Grasslands In Uganda, Elly N. Sabiiti, S. Mugasi, F. B. Bareeba Aug 2023

Use Of Forage Legumes To Restore Overgrazed Natural Grasslands In Uganda, Elly N. Sabiiti, S. Mugasi, F. B. Bareeba

IGC Proceedings (1977-2023)

The natural grasslands of Uganda support over 95 % of the country's livestock. They are also used by wildlife and protect soil resources from heat and erosion. Unfortunately, the pastoral/agro-pastoral communities which derive their livelihoods from these grasslands have in turn degraded them through overgrazing and uncontrolled burning, thus lowering their productivity (pasture and animal production) and biodiversity. The natural grasses (e.g. Panicum maximum, Brachiaria brizantha, Setaria anceps, Themeda triandra) mature rapidly and lose quality. Furthermore, the indigenous legumes (e.g. Neonotonia wightii, Desmodium adcsendens, Indigofera errecta) are less persistent and productive to maintain feed quality and hence animal …

Herders And Wetland Degradation In Northern Cameroon, E. Tedonkeng Pamo, F. Tendonkeng, J. R. Kana Aug 2023

Herders And Wetland Degradation In Northern Cameroon, E. Tedonkeng Pamo, F. Tendonkeng, J. R. Kana

IGC Proceedings (1977-2023)

Livestock rearing in Northern Cameroon is carried out under two majors systems: the nomadic and the transhumance production systems (Pamo & Pamo, 1991). Nomadism is the practice of wandering from place to place, while transhumance involves seasonal displacement of flocks from one area to another by herders. These production systems involved large grazing areas, which may encompass different ecosystems. The Yaére, the only wetland of the northern Cameroon, is the major dry season grazing lands for livestock and wildlife. The main characteristic of this wetland is that the whole area is excluded from grazing during the growing season as a …

Grazing Prohibition Programme And Sustainable Development Of Grassland In China, X. Y. Hou, L. Yang Aug 2023

Grazing Prohibition Programme And Sustainable Development Of Grassland In China, X. Y. Hou, L. Yang

IGC Proceedings (1977-2023)

Prohibition of grazing is now the main grassland management measure in China. From 1999, prohibition of grazing has been implemented on a trial basis in some areas. From 2001, the grazing prohibition programme (GPP) has been carried out in five provinces (Shaanxi, Gansu, Hebei, Jilin and Yunnan) and two autonomous regions (Inner Mongolia and Ningxia), with the objective of protecting and restoring grassland by seasonal or yearly banning of grazing with subsidiary assistances. The area within which grazing was prohibited of 2.93×107 ha in 2001 was increased to over 3.33×107 ha in 2004. With a view to improving …

Degraded Rangeland: Can The Balance Be Restored In The Absence Of Satisfactory Range Management Practices?, F. J. Mitchell, R. G. Bennett, B. D. Forbes, R. N. Reynolds Aug 2023

Degraded Rangeland: Can The Balance Be Restored In The Absence Of Satisfactory Range Management Practices?, F. J. Mitchell, R. G. Bennett, B. D. Forbes, R. N. Reynolds

IGC Proceedings (1977-2023)

The rangelands of KwaZulu-Natal play a fundamental role in the wealth and security of communal populations who are dependent on these forage-producing lands for their livelihoods. In most communal areas of the Province, there is an absence of satisfactory range management practices and the utilization of resources is generally non-sustainable. A major threat to the productivity of rangeland is inappropriate land use, such as overgrazing and incorrect burning practices, leading to extensive degradation of both the vegetative and soil components. Range vegetation and soil reserves show vastly reduced productivity. Degradation also results in increased susceptibility to erosion, loss of vegetative …

Contribution Of Grasses To Soil Fertility And Improved Livelihoods, G. P. Ojha, B. K. Dhital Aug 2023

Contribution Of Grasses To Soil Fertility And Improved Livelihoods, G. P. Ojha, B. K. Dhital

IGC Proceedings (1977-2023)

Vegetable farming is increasing in Nepal as it provides better economic returns than growing other crops, especially in areas that have easy access to markets. Vegetable farming demands intensive care and balanced supplies of nutrients. Therefore, farmers cultivate vegetables near their residence and because vegetable growing is more profitable, farmers allocate more resources, including organic manure, for its cultivation. In general, using more organic manure on vegetables means that less organic manure is available for non-vegetable crops and farms, unless alternative arrangements are made for producing more organic manure or manure of higher quality.

Transhumance In Protected Areas In Benin, E. A. Sogbohossou, Marcel Houinato, C. Tamou, K. Sounkere, Brice Sinsin Aug 2023

Transhumance In Protected Areas In Benin, E. A. Sogbohossou, Marcel Houinato, C. Tamou, K. Sounkere, Brice Sinsin

IGC Proceedings (1977-2023)

Every year, protected areas and regions in West Africa receive transhumant herds. This movement of herds from the dry zone (the Sahelian region) to more humid costal zones is a tradition for the Fulani people. In general, protected areas in West Africa are located at the border of the Sahelian zones through which most transhumants must pass. This periodic movement has an impact on natural resources and the people in the reception zones, especially around and in the protected areas. The objectives of the study were to define and describe the type of transhumant cattle breeding systems around these protected …

Sustaining The Multi-Functionality Of The Zamfara Reserve In Semi-Arid Nigeria: What Is The Role Of Co-Management?, B. F. Umar Aug 2023

Sustaining The Multi-Functionality Of The Zamfara Reserve In Semi-Arid Nigeria: What Is The Role Of Co-Management?, B. F. Umar

IGC Proceedings (1977-2023)

Unhealthy competition and conflicts among the diverse users (herders, farmers, fishermen, etc.) of the natural resources (pasture, water, land, etc.) in the Zamfara reserve, Nigeria have undermined the reserve's capacity to serve its intended multi-functional roles. The reserve (3, 650 km2), which was established in 1919 with 4 enclave villages where farmers live and cultivate crops, was meant also to provide pasture and water for Fulani herdsmen. Vast numbers of people are, however, becoming landless or near landless in the reserve. Powerful non-local actors are forcing their way into the reserve area and are extracting resources with no respect to …

Land Subdivision, Heterogeneity, And Declining Food Security For African Pastoralists, R. B. Boone Aug 2023

Land Subdivision, Heterogeneity, And Declining Food Security For African Pastoralists, R. B. Boone

IGC Proceedings (1977-2023)

Pastoral livestock inhabit landscapes that are spatially heterogeneous and have forage patches that pulse in their value to animals. Mobile pastoralists have evolved movement patterns to maximize use of these ephemeral food sources. In pastoral communities across Africa, changes in land tenure policy and socioeconomic pressures have caused pastoralists to decrease their mobility. Pastoralists recognize that shrinking access to land reduces their options to find forage, and theory suggests that the capacity of land to support herbivores decreases as a power of the square root of area accessible. We used ecosystem modelling in South Africa and Kenya to quantify declines …

Factors Related To Marketing Successes For Fibre Producers In Middle Asia, R. B. Boone, K. A. Galvin Aug 2023

Factors Related To Marketing Successes For Fibre Producers In Middle Asia, R. B. Boone, K. A. Galvin

IGC Proceedings (1977-2023)

Following the collapse of the Soviet Union in the early 1990s, the economic well-being of livestock producers of Kazakhstan and Kyrgyzstan declined dramatically (see Kerven 2003; Kerven et al., 2003). Like the economies in general, the livestock economies are slowly recovering and restructuring. Livestock producers have been encouraged by international market prices to raise sheep, goats, camels, and animals producing specialty fibre. Fine-fibre sheep and goats remain in Kazakhstan and Kyrgyzstan, but marketing of fibres from the region is not ideal. As examples, sheep pelts are not sorted and graded, which is expected by international buyers, and cashmere is …

Task Force Development To Provide Education And Leadership To The Meat Goat Industry, Jeffrey C. Fisher, L. A. Nye, D. A. Mangione Aug 2023

Task Force Development To Provide Education And Leadership To The Meat Goat Industry, Jeffrey C. Fisher, L. A. Nye, D. A. Mangione

IGC Proceedings (1977-2023)

Chevon is the most frequently consumed meat in the world. Meat goat production is increasing because of the economic value of goats as efficient converters of low-quality forages into quality meat, milk, and hide products for specialty markets of health conscious, ethnic, and faith based consumers. Estimates of national marketing indicate that U.S. meat goat production is nearly 500,000 head less than demand. Where resources are limited, meat goats can be raised efficiently and profitably on small farms, so the country could become self-sufficient in meat goats.

Cashmere Marketing Is A New Income Source For Central Asian Livestock Farmers, R. H. Behnke, C. Kerven, S. Aryngaziev, N. Malmakov, H. Redden, A. Smailov, K. A. Galvin Aug 2023

Cashmere Marketing Is A New Income Source For Central Asian Livestock Farmers, R. H. Behnke, C. Kerven, S. Aryngaziev, N. Malmakov, H. Redden, A. Smailov, K. A. Galvin

IGC Proceedings (1977-2023)

Some indigenous goats in the Central Asian republics of Kazakstan, Kyrgyzstan and Tajikistan produce good quality cashmere (Millar 1986). International processors have recently been buying this cashmere. (Kerven et al., 2005), but Central Asian producers are not equipped to take full advantage of these new marketing opportunities. The U.S. AID Global Livestock-Collaborative Research Support Program project, "Developing Institutions and capacity for sheep and fiber marketing in Central Asia" is working to increase the income of small-scale livestock farmers through improved cashmere marketing.

Production Strategies Of Livestock Herders In The Grasslands Of Kazakhstan: Implications For The Marketing Of Fine Fibres, Kathleen A. Galvin, C. Kerven, R. B. Boone, A. Smailov Aug 2023

Production Strategies Of Livestock Herders In The Grasslands Of Kazakhstan: Implications For The Marketing Of Fine Fibres, Kathleen A. Galvin, C. Kerven, R. B. Boone, A. Smailov

IGC Proceedings (1977-2023)

Goat populations have been rising in Kazakhstan over the past ten years since independence and goats are preferred by farmers trying to restock. Quality of cashmere production is the key to profitable and sustainable sales to world markets for this luxury good. However, Kazakhstan did not develop a cashmere industry in the Soviet period so today goats are sheared rather than combed and little profit is made from cashmere. Goats, as well as sheep and camels are currently multi-purpose animals providing income from sales of animals, cashmere, milk and meat. This will change as the terms of trade change for …

Adding Value To Grasslands Through Certified Organic Beef Production, G. Ferreira, F. Pittaluga, C. Mas, S. Revello, R. Tellería Aug 2023

Adding Value To Grasslands Through Certified Organic Beef Production, G. Ferreira, F. Pittaluga, C. Mas, S. Revello, R. Tellería

IGC Proceedings (1977-2023)

New demands are being made for safe beef from low input production systems (low input of energy, pesticides, other chemically synthesised products and hormones and GM free) by the main retailers and consumers (Howard, 2004). These present an opportunity for adding value to grazing production systems and to reinforce relationships among farmers, agro-industrialists, exporters and consumers and to show advantages of positive externalities of grasslands (Meister, 2001).

Alternative Land Use Options For Philippine Grasslands: A Bioeconomic Modeling Approach Using The Wanulcas Model, D. B. Magcale-Macandog, E. Abucay, P. A. B. Ani

IGC Proceedings (1977-2023)

In the Philippines, pure grasslands occupy 1.8 million ha and another 10.8 million ha (33% of the country's total land area) is under extensive cultivation mixed with grasslands and scrub. Most of these grasslands are under-utilised and dominated by Imperata cylindrica. Imperata grasslands generally represent areas of degraded soils that are acidic, low in organic matter and susceptible to erosion. However, conversion of these grassland areas into upland farms planted to annual crops and perennial trees is proliferating at a fast rate. This is triggered by the interacting factors of rapidly increasing population, the system of landholding, scarcity of …

Are New Farming Systems Based On Perennial Pastures In South West Australia More Profitable?, Paul Sanford, J. Young Aug 2023

Are New Farming Systems Based On Perennial Pastures In South West Australia More Profitable?, Paul Sanford, J. Young

IGC Proceedings (1977-2023)

Traditional farming systems in south west Australia based on annual plants have been shown to use insufficient water leading to excess leakage below the root zone, groundwater rise and eventually salinisation of the landscape. Introduction of deep-rooted summer active perennial plants can significantly increase water-use thus reducing the risk of salinisation. However the adoption of perennials by farmers is also dependent on their effect on economic factors. This paper reports an analysis of the impact of perennials on whole farm profit.

Lucerne Production And Economics On Stakeholder Ranches On Coastal Plain Acid Soils, V. A. Haby, A. T. Leonard, G. M. Clary, F. M. Rouquette Jr., L. A. Redmon Aug 2023

Lucerne Production And Economics On Stakeholder Ranches On Coastal Plain Acid Soils, V. A. Haby, A. T. Leonard, G. M. Clary, F. M. Rouquette Jr., L. A. Redmon

IGC Proceedings (1977-2023)

Research using small plots determined factors restricting lucerne (Medicago sativa) production on Coastal Plain soils of the southern USA. These acid soils, primarily Ultisols and Alfisols, become deficient in B when limed to pH 6.8 or 7.0 for lucerne. Other production-limiting soil problems include poor drainage and aeration, subsoil acidity, and low natural fertility. The objective of this study was to evaluate stand longevity on hectare-size stakeholder fields when growth-limiting factors were eliminated by site selection and soil treatment.
