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.

Water Soluble Carbohydrate Content Of Two Cultivars Of Perennial Ryegrass (Lolium Perenne) At Eight European Sites, Magnus A. Halling, A. C. Longland, S. D. Martens, L. Nesheim, P. O'Kiely Jun 2023

Water Soluble Carbohydrate Content Of Two Cultivars Of Perennial Ryegrass (Lolium Perenne) At Eight European Sites, Magnus A. Halling, A. C. Longland, S. D. Martens, L. Nesheim, P. O'Kiely

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.

Rumen Degradation Characteristics Of Four Species Of Native Pastures From Central Mexico In Three Growing Periods, A. A. Rayas, A. M. J. Espinoza‐Ortega, J. G. Estrada‐Flores, C. Arriagal, F. Mould, O. A. Castelán-Ortega Jun 2023

Rumen Degradation Characteristics Of Four Species Of Native Pastures From Central Mexico In Three Growing Periods, A. A. Rayas, A. M. J. Espinoza‐Ortega, J. G. Estrada‐Flores, C. Arriagal, F. Mould, O. A. Castelán-Ortega

IGC Proceedings (1977-2023)

The smallholder cattle systems of the Toluca valley in central Mexico are based on the use of maize and native grasses. Research has been devoted to nutritional characterisation of improved pastures, but native species of grasses have not been studied, despite their importance. The aim of this experiment was to evaluate the in vitro rumen degradation kinetics of four species of native pastures.

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 …

Stylo In China: A Tropical Forage Legume Success Story, Guodao Liu, S. Chakraborty Jun 2023

Stylo In China: A Tropical Forage Legume Success Story, Guodao Liu, S. Chakraborty

IGC Proceedings (1977-2023)

Although Stylosanthes gracilis was the first stylo to be introduced as a green manure cover crop for young rubber plantations in 1961, the S. guianensis cultivars Cook and Graham introduced in the 1970s and 1980s were largely responsible for the stylo revolution in China. Before serious anthracnose outbreaks, these cultivars covered over 13,000 ha in southern China. Anthracnose had shifted emphasis to S. guianensis CIAT184 and successful cultivars originate from this introduction (Guodao et al., 2004). Well-adapted varieties are now available for much of southern China and in 2003, the total area of stylo exceeded 200,000 ha. Stylo development …

Intake, Digestibility And Rate Of Passage Of Grass In Grazing By Light Breed Horses On Different Pastures, Masahito Kawai, N. Yabu, T. Asa, K. Deguchi, S. Matsuoka Jun 2023

Intake, Digestibility And Rate Of Passage Of Grass In Grazing By Light Breed Horses On Different Pastures, Masahito Kawai, N. Yabu, T. Asa, K. Deguchi, S. Matsuoka

IGC Proceedings (1977-2023)

In a previous study, grazing light breed horses could ingest CP and DE requirements for maintenance without supplements. However, their grazing behaviour, such as biting and chewing efficiency, which related to the passage rate of forage in the digestive tract and fibre digestibility, was affected by the pasture conditions (Kawai et al., 2004). In this study, the DM intake, digestibility and mean retention time (MRT) of grass in light breed horses were determined and compared in spring, summer and autumn on an improved pasture.

Sustainable Semi-Arid Grazing Management Based On Indigenous Shona Practices Prior To Introduction Of Western Ideas In Zimbabwe, O. Mugweni, R. Mugweni Jun 2023

Sustainable Semi-Arid Grazing Management Based On Indigenous Shona Practices Prior To Introduction Of Western Ideas In Zimbabwe, O. Mugweni, R. Mugweni

IGC Proceedings (1977-2023)

In the Shona culture the land, i.e. the plants, animals, soil, water, air and others, evolved with herding animals. Hence, the absence of one results in the destruction of the other. It is argued that the conventional grazing management belief that too many animals cause overgrazing is a misconception of the semi-arid savanna environments of Southern Africa where these environments evolved with thousands of herding grazers and mega-faunas such as elephants, wildebeests and buffalo. The objective of the research is to establish that grazing with an adequate recovery period for grazed plants, as a result of domesticated animals being managed …

How Are Distances Between Grazing Cows Determined?, Masae Shiyomi Jun 2023

How Are Distances Between Grazing Cows Determined?, Masae Shiyomi

IGC Proceedings (1977-2023)

Although domestic cows are protected from their natural enemies, they form herds when grazing like their wild forbears did. The herding instinct is used to manage cattle because it is easier to control a herd than separate individuals. This study examined how distances between individual grazing cows are determined.

Catch-Up In Response To Elevated Co2 - A Study Of Genotypes Of 12 Grassland Species, E. Wright, John Connolly, Andreas Lüscher Jun 2023

Catch-Up In Response To Elevated Co2 - A Study Of Genotypes Of 12 Grassland Species, E. Wright, John Connolly, Andreas Lüscher

IGC Proceedings (1977-2023)

Differential growth enhancements for species or genotypes under elevated CO2 can lead to changes in the composition of plant communities. Under a Rich-get-richer hypothesis, species that constitute a large proportion of a community (the dominants) will increase their dominance at elevated CO2 (Bazzaz and Garbutt, 1988). Under the alternative Catch-up hypothesis the smaller components of communities will benefit proportionately more than dominants from elevated CO2 conditions (tested at the level of individual plants in a monoculture in Wayne and Bazzaz, 1997). A recent review (Poorter & Navas, 2003) provided no evidence for differential growth enhancements by dominant …

The Timing Of Daily Grazing On Annual Ryegrass Or Sulla Forage: The Effects On Milk Yield And Composition Of Comisana Ewes, D. Giambalvo, L. Stringi, C. Scarpello, P. Iudicello, A. Bonanno, A. Di Grigoli Jun 2023

The Timing Of Daily Grazing On Annual Ryegrass Or Sulla Forage: The Effects On Milk Yield And Composition Of Comisana Ewes, D. Giambalvo, L. Stringi, C. Scarpello, P. Iudicello, A. Bonanno, A. Di Grigoli

IGC Proceedings (1977-2023)

The timing and duration of grazing greatly affect the response of animals. Night grazing, in addition to grazing during the day, seems to be one of the most important practices for improving animal performance (Bayer et al., 1987). Many authors have already underlined the major benefits of night grazing, such as improved body condition, reduced heat stress, increased forage intake and milk production. However, labour constraints, insecurity, damage to crops by animals are considered as the main reasons for not practising day and night grazing. The aim of this research was to improve knowledge about the effects of daily …

Herbage Production Of Tanzania Grass (Panicum Maximum Cv. Tanzania) Submitted To Combinations Of Frequencies And Intensities Of Grazing By Cattle, Domicio Nascimento Jr., Rodrigo A. Barbosa, Valéria P. B. Euclides, S. C. Da Silva, R. A. Torres Jun 2023

Herbage Production Of Tanzania Grass (Panicum Maximum Cv. Tanzania) Submitted To Combinations Of Frequencies And Intensities Of Grazing By Cattle, Domicio Nascimento Jr., Rodrigo A. Barbosa, Valéria P. B. Euclides, S. C. Da Silva, R. A. Torres

IGC Proceedings (1977-2023)

Animal production from pastures is a complex process comprising three main stages: herbage growth, consumption by grazing animals and conversion into animal products (Hodgson, 1990). Utilisation is the stage where the grazier finds greater flexibility for management, probably because most processes related to harvest of the produced herbage by the grazing animals are very responsive to manipulation and control of defoliation practices. The objective of this study was to evaluate herbage production of a Panicum maximum cv. Tanzania pasture submitted to combinations of frequencies and intensities of grazing.

The Effects Of Proximity To Watering Points On Vegetation Parameters In Winter Rangelands Of Chahe-Nou, Damghan, Iran, R. Khalifeh-Zadeh, Mansour Mesdaghi Jun 2023

The Effects Of Proximity To Watering Points On Vegetation Parameters In Winter Rangelands Of Chahe-Nou, Damghan, Iran, R. Khalifeh-Zadeh, Mansour Mesdaghi

IGC Proceedings (1977-2023)

The Chahe-Nou with 115 mm rainfall and high temperatures (30 °C) is located 95 km south of Damghan. It is grazed intensively by nomadic and sedentary sheep and goats during winter. Proximity to watering points affects the rangelands vegetation. With increasing distance from the watering points more palatable species increase, whilst grazing decreases. The areas nearest the watering points contain more unpalatable undesirable invasive species (Department of Natural Resources, 1999). The objective of this research was to evaluate the effects of proximity to watering point on vegetation parameters at two watering points.

Grazing Behaviour Of Lambs In Different Production Systems, C. H. E. C. Poli, Alda L. G. Monteiro, C. S. Gomes, G. J. Bosquetto, J. R. Dittrich, Susana Gilaverte, H. V. L. Piazetta Jun 2023

Grazing Behaviour Of Lambs In Different Production Systems, C. H. E. C. Poli, Alda L. G. Monteiro, C. S. Gomes, G. J. Bosquetto, J. R. Dittrich, Susana Gilaverte, H. V. L. Piazetta

IGC Proceedings (1977-2023)

Ingestive behaviour is an important component of a grazing system (Fryxell et al., 2001). The understanding of lamb behaviour patterns in different production systems is crucial to management and to assess the impact of the production system on the use of resources by animals. The objective of this study was to determine the grazing behaviour of lambs in different production systems.

Effect Of Red And White Clover Added To A Rye Grass-Based Diet On Intake, Fibre Digestion And Methane Release Of Dairy Cows, Anette H. Van Dorland, Michael Kreuzer, M. Leuenberger, H. R. Wettstein Jun 2023

Effect Of Red And White Clover Added To A Rye Grass-Based Diet On Intake, Fibre Digestion And Methane Release Of Dairy Cows, Anette H. Van Dorland, Michael Kreuzer, M. Leuenberger, H. R. Wettstein

IGC Proceedings (1977-2023)

Forage legumes like white and red clover are widely grown in association with grass, with the intention to improve the quality of grass-based diets. However little is known about the effect of either white or red clover added to a grass-based diet on methane release, and existing studies are not conclusive. The objective of this study, applying the respiratory chamber technique, was to determine the effect of red and white clover added to a rye grass-based diet on intake, fibre digestion and methane release of dairy cows.

Reproductive Allocation In Brassica Kaber, Caroline Brophy, John Connolly, P. M. Wayne, D. J. Gibson Jun 2023

Reproductive Allocation In Brassica Kaber, Caroline Brophy, John Connolly, P. M. Wayne, D. J. Gibson

IGC Proceedings (1977-2023)

Understanding the reproductive biology of weeds is essential to understanding their role in seminatural plant communities. The annual forb Brassica kaber is an important agricultural weed in the mid-western regions of the U.S.A. Linear regression is often used to establish the relationship between the reproductive mass (R) of a plant (as measured by number of flowers, seeds or mass of reproductive organs) and its dry mass (W)(Sletvold, 2002). Some plants do not have any reproductive output (R=0). These zero values cause a problem forlinear regression. Schmid et al. (1994) suggested using truncated regression as a solution. In this presentation …

Proanthocyanidins From Hedysarum, Lotus And Onobrychis Spp. Growing In Sardinia And Sicily And Their Antioxidant Activity, A. Tava, M. G. De Benedetto, D. Tedesco, G. Di Miceli, G. Piluzza Jun 2023

Proanthocyanidins From Hedysarum, Lotus And Onobrychis Spp. Growing In Sardinia And Sicily And Their Antioxidant Activity, A. Tava, M. G. De Benedetto, D. Tedesco, G. Di Miceli, G. Piluzza

IGC Proceedings (1977-2023)

Proanthocyanidins (PA), or condensed tannins, are a class of natural polyphenolic compounds, occurring in numerous plant species, including a number of economically significant forage legumes. These compounds are polymers of flavan-3-ols, and typically contain from 2 to 20 units. Their biological significance is still being debated and, in recent years, a great deal of attention has been focused on their role in ruminant nutrition. Evidence has indicated that PA, in a moderate concentration (0.5-5% DM), may have considerable importance in protecting dietary proteins against microbial degradation in the rumen, and in preventing bloat. The antioxidant activity (AA) is also an …

Carbon Sequestration In Irrigated Pastures, Glenn E. Shewmaker, J. A. Entry, R. E. Sojka Jun 2023

Carbon Sequestration In Irrigated Pastures, Glenn E. Shewmaker, J. A. Entry, R. E. Sojka

IGC Proceedings (1977-2023)

Carbon sequestration potential for irrigated grazing lands is significant. We measured organic and inorganic C stored in southern Idaho soils having long-term land use histories that supported native sagebrush vegetation (NSB), irrigated pasture systems (IP), irrigated conservation tillage sites (ICT), and irrigated moldboard plowing systems (IMP). This study estimates the amount of possible organic, inorganic and total C sequestration if irrigated pasture land was expanded by 10%.

The Carbon Balance Of Long Term And Newly Established Temperate Grasslands, J. Clifton-Brown, G. Lanigan, R. B. Taylor, J. I. Burke, M. B. Jones Jun 2023

The Carbon Balance Of Long Term And Newly Established Temperate Grasslands, J. Clifton-Brown, G. Lanigan, R. B. Taylor, J. I. Burke, M. B. Jones

IGC Proceedings (1977-2023)

Carbon (C) sequestration is the process of removing CO2 from the atmosphere and storing it in C pools of varying lifetime. Storage can be in the form of above-ground biomass, below-ground biomass or recalcitrant organic and inorganic C in the soil. While the processes of C sequestration are ultimately regulated at the molecular level, management practices and climate can greatly affect the way in which terrestrial ecosystems sequester C (Soussana et al., 2004). Because temperate grasslands account for a significant portion of the agricultural and semi-natural land-cover in N-W Europe any increase in the potential of temperate grasslands …

Carbon Sequestration In Pasture And Silvo-Pastoral Systems In Ecosystems Of The Latin American Tropics, M. C. Amézquita, M. Ibrahim Jun 2023

Carbon Sequestration In Pasture And Silvo-Pastoral Systems In Ecosystems Of The Latin American Tropics, M. C. Amézquita, M. Ibrahim

IGC Proceedings (1977-2023)

Conversion of forests to pastures has been the most important land use change in tropical America (TA) in the last fifty years. After deforestation and pasture establishment many areas have been abandoned due to productivity declines arising through mismanagement. Over 60% of the TA's pasture area is degraded. Recent interest in carbon sequestration and environmental considerations might suggest partial reforestation of current pastoral areas but this has implications for the socio-economic welfare of farmers and food availability. However, combining agricultural production with environmental objectives (particularly carbon sequestration) could provide a sustainable alternative. Here we present 3-years of research on the …

IGC Proceedings (1977-2023)

Concerns about the environmental impact of nitrogen (N) losses in Australia, in particular, nitrous oxide emissions are related to the rapid increase in N application on dairy pastures. Computer modelling is the most suitable method available to assess the potential of best management practices (BMP) to reduce field losses, as direct field measurements are frequently limited by the short term nature of many field trials.

Time Budget On Major Activities Of Livestock Grazing Heterogeneous Natural Range And Crop Fields In Semi-Arid Nigeria, B. S. Malami, P. H. Y. Hiernaux, H. M. Tukur, J. Steinbach Jun 2023

Time Budget On Major Activities Of Livestock Grazing Heterogeneous Natural Range And Crop Fields In Semi-Arid Nigeria, B. S. Malami, P. H. Y. Hiernaux, H. M. Tukur, J. Steinbach

IGC Proceedings (1977-2023)

Semi-arid rangelands of West Africa provide herbs, trees and shrubs, which together with crop residues form the main sources of feed for the livestock population. Feed supply in this region is characterised by a progressive decline in quantity and quality with advancing dry season. It was reported that walking ability as well as watering frequencies affect the productivity of grazing livestock (Dicko and Sangare, 1984). This study tests the hypothesis that advancing season increases both time spent walking as well as feeding, with a switch from grazing to browsing.

Effect Of Time Spent On Pasture On Grazing Behaviour In Latxa Dairy Sheep, A. Garcia-Rodriguez, N. Mandaluniz, L. M. Oregui Jun 2023

Effect Of Time Spent On Pasture On Grazing Behaviour In Latxa Dairy Sheep, A. Garcia-Rodriguez, N. Mandaluniz, L. M. Oregui

IGC Proceedings (1977-2023)

In the Basque country the dairy ewe production system is based on a high pasture utilisation by means of partial time grazing where ewes spend a limited number of hours outdoors (Oregui et al., 1997). This production system, which is also typical of other Mediterranean areas, is different from that in northern Europe where continuous grazing is the usual management. There is a lack of knowledge concerning grazing behaviour under these conditions. This research investigated the effect of time spent on pasture on grazing behaviour.
