Stylos: The Broad Acre Legumes Of N Australian Grazing Systems, John P. Rains
IGC Proceedings (1977-2023)
Early accidental introduction of Stylosanthes humilis into the N Australian savannas in the early 20th century and its contrived spread by the late 1960s led to the release of more perennial types. Townsville Stylo, as it was known, colonised large areas and had reached its climatic and agronomic limits by the 1970s. It had a major impact on beef production in areas where natural carrying capacities were relatively low. The precedent of Townsville Stylo directed attention to the genus Stylosanthes. This impact continued until 1974 when anthracnose virtually wiped it out. Fortunately 2 other Stylosanthes species, S. hamata cv. Verano …

Leucaena In Northern Australia: A Forage Tree Legume Success Story, B. F. Mullen, H. M. Shelton, Scott A. Dalzell
IGC Proceedings (1977-2023)
Leucaena leucocephala (leucaena) is a long-lived, perennial forage tree legume of very high nutritive value for ruminant production. In northern Australia, leucaena is direct seeded into hedgerows 5-10m apart, with grass species such as buffel grass (Cenchrus ciliaris) planted in the inter-row to form a highly productive and sustainable grass-legume pasture that cattle graze directly. It generally is grown on deep, fertile soils in sub-humid environments with average rainfall of 600-800mm/year. Steer gains of 275-300kg/head per year are achieved, with short-term daily gains over the main growing season > 1kg/head. Being very deep-rooted, leucaena exploits moisture beyond the reach …

Aeschynomene And Carpon Desmodium: Legumes For Bahiagrass Pasture In Florida, Lynn E. Sollenberger, R. S. Kalmbacher
IGC Proceedings (1977-2023)
Soils and climate are very diverse across Florida, and no single legume has state-wide adaptation. However, aeschynomene (Aeschynomene americana), an annual, and carpon desmodium (Desmodium heterocarpon) cv. Florida, a perennial, are the most commonly used legumes for grazing on the central and southern peninsula, which produces 65% of Florida's beef calves. Both grow well with bahiagrass (Paspalum notatum), which is the main pasture grass, with ~1M ha state-wide. Circa 65K ha of bahiagrass contain at least limited quantities of aeschynomene and 14K ha contain carpon desmodium.

Rhizoma Peanut: More Than A ‘Lucerne’ For Subtropical Usa, M. J. Williams, K. H. Quesenberry, G. M. Prine, C. B. Olson
IGC Proceedings (1977-2023)
Rhizoma peanut (Arachis glabrata) was introduced to Florida from South America in the 1930s. Selections 'Arb' (PI 118457) and 'Arblick' (PI 262839) were released in the 1960s, but their use was very limited due to slow establishment and low productivity. The University of Florida released 'Florigraze' (PI 421707) in 1978 and 'Arbrook' (PI 262817) in 1986. These cultivars produced much higher dry matter yields. Thereafter, rhizoma peanut began to gain commercial acceptance. These cultivars are used throughout the Gulf Coast region of the USA for commercial hay production, pasture, creep grazing, silage, balage, and living mulch (French et …

Species And Chlorine Fertilisation Affect Dietary Cation-Anion Difference Of Cool-Season Grasses, Gilles Bélanger, Sophie Pelletier, H. Brassard, Gaëtan F. Tremblay, Philippe Seguin, R. Drapeau, A. Brégard, Réal Michaud, Guy Allard
IGC Proceedings (1977-2023)
The Dietary Cation-Anion Difference [DCAD = (Na + K) - (Cl + S); Ender et al., 1971] is used in balancing rations for dry dairy cows. Low DCAD diets induce a mild, compensated metabolic acidosis that stimulates bone resorption, improves Ca homeostasis, and prevents milk fever. Dry cow rations contain a high proportion of forage and, therefore, forages fed two to four weeks prepartum should have a low or negative DCAD value. Our objectives were to evaluate the DCAD of five cool-season grass species grown in eastern Canada and to determine the effect of Cl fertilisation on the DCAD …

Forage Quality Of Cool Season Pasture Species Under Two Rotational Grazing Height Regimes, H. D. Karsten, M. Carlassare
IGC Proceedings (1977-2023)
To optimize animal and pasture performance in management intensive grazing systems, pasture production and quality often must be compromised. Rotationally-stocking pastures at slightly taller grazing heights can increase pasture productivity, but lower forage quality may limit animal performance. Our objective was to compare the forage quality of common cool season pasture species in the Northeastern U.S., under two rotational grazing regimes defined by slightly different grass heights.

Investigation Into Differences In Palatability Among Festulolium Varieties As Haylage, E. Touno, S. Kushibiki, H. Shingu, A. Oshibe
IGC Proceedings (1977-2023)
In Japan, paddy fields that are no longer used for cultivation of rice are being converted to cultivation of forage crops. Therefore, grass with greater wet resistance and higher quality is required. Festulolium is an interspecific hybrid between the Lolium and Festuca species and combines the characteristics of high-quality ryegrass and resistance to hostile environments from fescues (Thomas & Humphreys, 1991). Among festulolium varieties, there is wide variation in environmental resistance and feeding value. One festulolium variety, Paulita, shows superior wet resistance to Evergreen and the total digestible nutrients of Evergreen was similar to that of cocksfoot (cv. Kitamidori) (Touno …

The Feeding Value Of Silage Made From Peas Grown Alone Or In Mixture With Cereals, A. Kirilov
IGC Proceedings (1977-2023)
The interest in pea as a forage crop rich in protein does not decrease. In areas frequent summer drought pea (Pisum sativum) as a whole plant for forage gives assured yield and may be used for zero grazing, hay or silage. The winter varieties use winter-spring soil moisture better and give higher yield than the spring varieties, but they lodge, so it is necessary to sow them with supporting cereal crops to increase lodging resistance. The objective of the study was to compare the intake, digestibility, energy value and quality index of two wilted silage made from winter …

Annual Legumes As An Alternative For Animal Feeding In Cuba, María Felicia Díaz, C. Padilla, E. Lon Wo, M. Castro, R. S. Herrera, R. O. Martínez
IGC Proceedings (1977-2023)
Studies conducted in Cuba have demonstrated the importance of the agronomic and nutritional performance of the species Vigna unguiculata (cowpea), Canavalia ensiformis (jackbean), Stizolobium niveum (mucuna), Lablab purpureus (dolicho) and Glycine max (soybean) as feed sources for non-ruminant species. Under Cuban tropical conditions, and with minimum agricultural inputs, jackbean, dolicho and mucuna have attained forage yields between 4 and 6 t dry matter (DM)/ha and grain yields between 2.57 and 3.41 t/ha and cowpea and soybean have given yields of between 1 and 2 t/ha (Díaz 2000). This study was carried out to determine the chemical composition of grains and …

Relative Yields And Nutritive Value Of Whole Crop Rice Harvested On Four Successive Dates For Forage In Korea, Jong-Geun Kim, Y. C. Lim, E. S. Chung, S. H. Yoon, S. Seo, M. J. Kim
IGC Proceedings (1977-2023)
About four million tons of forages are fed to ruminants in Korea, but half of them rely on rice straw as roughage and 0.6 million tons of forage was imported. The lack of forage results in increased imports of concentrate feeds and increased production cost. Now, Korea has about 1.1 million ha of rice fields, but as a consequence of world trade negotiation, Korea will open the rice market from next year. It is expected that due to aging farmers and lower rice price, about 0.2 million ha of paddy field will not be cultivated for grain rice. Therefore, we …

Nutritional Evaluation Of Banana Peelings From The Various Banana Varieties In Different Regions Of Uganda, J. Nambi-Kasozi, Elly N. Sabiiti, F. B. Bareeba, E. Sporndly
IGC Proceedings (1977-2023)
In Uganda, peri-urban agriculture is very important in sustaining livelihoods of the increasing population in urban and peri-urban (U & PU) areas. However, this form of agriculture has a number of problems, feed shortage being the most important. The agricultural produce brought in from the rural areas is marketed in raw form hence increasing the crop wastes in the market areas. The crop wastes, if properly sorted, can serve as alternative feeds for the animals kept in the U & PU areas. Banana (Musa spp) peelings (BP) constitute the largest proportion of all the crop wastes in most …

Changes In Grass Quality Of Coastal Meadows In Estonia, Tiina Köster, Karin Kauer, R. Viiralt, A. Selge
IGC Proceedings (1977-2023)
In Estonia the reason for reduction in coastal meadows and expansion of the stands of the common reed (Phragmites australis) is the discontinuation of traditional use of grasslands which were previously grazed and cut. Phragmites australis usually produces dense and monospecific stands at the waterline, where species richness is low. It can survive in ungrazed shore meadows, but it suffers from grazing (Tyler, 1969). The investigated Phragmitetum australis association had been influenced by grazing activities, but it remained rather sparse and due to that had relatively low productivity, reaching 3.11 t DM/ha. Traditionally coastal meadows have been used …

Accumulation Of Zearalenone In Herbage Of Winter Pasture Situated In West Poland, P. Goliński, M. Kostecki, Barbara Golińska, B. T. Golińska, P. K. Goliński
IGC Proceedings (1977-2023)
The importance of winter pastures in beef production in Europe has been growing steadily. In Poland, especially in its western part, there are already farms which utilise pasture swards during late autumn and winter. The major problem, however, is the quality of forage ingested by animals as it tends to deteriorate with the passage of the vegetation season with danger of accumulation of various mycotoxins (Laser et al., 2003) of which the most important is zearalenone (ZEA).

Diversity And Variation In Nutritive Value Of Plants Growing On 2 Saline Sites In Southwestern Australia, Hayley C. Norman, R. A. Dynes, D. G. Masters
IGC Proceedings (1977-2023)
In south-western Australia 10% or 1.8 million ha of the farmed area is affected by dryland salinity and a further 6 million ha are at risk of salinity (NLWRA, 2001). Animal production from saltbush (Atriplex spp.)-based pasture systems represents the most likely large-scale opportunity for productive use of saline land in the short to medium term. Feeding saltbush-based pastures as a maintenance feed during the prolonged autumn feed gap typical in Mediterranean-type climates maximises their economic value. The aim of this study was to explore the diversity and nutritive value of plants that typically persist in saltbush-based saltland pastures.

IGC Proceedings (1977-2023)
Livestock production is increasing in Mozambique. This trend, however, is facing such challenges as land tenure, erratic and not well-distributed rainfall (resulting in floods or droughts), overgrazing, wildfires, and the unsustainable resource management practices of communities. The study objectives were to evaluate forage species occurrence and seasonal variation and to estimate grassland productivity, nutritive value and savanna carrying capacity.

Forage Composition And Quality Of Tankbed Grassland Ecosystems In Sri Lanka; A Preliminary Study Of “Tabbowa” Tank, G. G. C. Premalal, Sujatha Premaratne
IGC Proceedings (1977-2023)
Although, Sri Lanka does not have large natural lakes, the early settlers devoted their energy to build water bodies (tanks or reservoirs) in association with forest catchments to provide water for irrigation. The tank bed is a grassland area of the tank, which lies between the catchment forest and the present water level. In general, the tankbed has three major zones - lower, middle and upper - and in some seasons the middle and upper parts may be underwater. This tankbed area is dominated by grassland vegetation and is a valuable feeding ground for free-grazing livestock. The main objective of …

Variations In Nutritive Values Of Two Different Desert Forage Plants Growing In The United Arab Emirate Environment, T. Ksiksi, A. Bamakhrama, M. Satri
IGC Proceedings (1977-2023)
Forage plants in desert environments have to withstand both shortages in resources and over grazing during most years. This variation in resource availability is associated with variation in the nutritive values of the plant species. Moreover, these differences are not only seasonal but also vary between plant parts. Variations in nutritive values in key species, therefore, need to be better understood in order to sustainably feed livestock (Abdurazak et al., 2000), because effective management requires adequate knowledge of the interaction between the animal, the pasture and the environment (Kassilly, 2002). Forage toxicity could, however, cause irreparable damage to production. …

Factors Affecting Forage Quality Of Native Species In Iranian Rangelands, Hossein Arzani, J. Torkan, H. Kaboli, M. Zohdi
IGC Proceedings (1977-2023)
Animal performance is closely correlated with the nutrient value of the forage available and this is affected by different factors (Arzani et al., 2001). Crude protein content (CP), digestible dry matter (DDM) and metabolisable energy (ME) were considered particularly appropriate for evaluation of range forage quality. This paper reports on factors affecting the forage quality of range species grown in Iran.
