The Dry Matter Yield And Nutritive Value Of Wet Tolerant Tropical Forage Legumes In Single Cropping Or Mixed Cropping With Gramineous Forage Crops In Drained Paddy Field, Manabu Tobisa, Y. Nakano, K. Okano, Masataka Shimojo, Yasuhisa Masuda Jun 2023

The Dry Matter Yield And Nutritive Value Of Wet Tolerant Tropical Forage Legumes In Single Cropping Or Mixed Cropping With Gramineous Forage Crops In Drained Paddy Field, Manabu Tobisa, Y. Nakano, K. Okano, Masataka Shimojo, Yasuhisa Masuda

IGC Proceedings (1977-2023)

In Japan the production of rice has been controlled since the 1970's and some parts of the paddy fields have been laid off for forage production. However, in poorly-drained fields or fields with high ground water table, forage species with high tolerance of wet conditions are required. The tropical forage legumes Aeschynomene americana cv. Glenn (Glenn) and Macroptilium lathyroides (L.) Urb. cv. Murray (phasey bean) have a high wet endurance (Bishop et al., 1985; Tobisa et al., 1999) and show high dry matter productivity (Skerman et al., 1988; Tobisa et al., 1999). The objective of this …

Desmanthus: A New Forage Legume To Improve Wool Growth In Tropical Australia, J. H. De A. Rangel, Carlos A. M. Gomide

IGC Proceedings (1977-2023)

In tropical Australia, very short and erratic wet seasons are the critical factors in determining forage growth and animal production (Wheeler & Freer, 1986). Grasses are highly susceptible to low rainfall and animal production in such conditions become strictly seasonal. Improvements in meat and wool production by the introduction of stylo species (Stylosanthes sp.) into natural grasslands have been intensively reported (Gillard & Winter, 1984). However, there are currently no suitable introduced legumes for the c.28 million ha of Mitchell grass (Astrebla spp.) plains in heavy clay soils of western North Queensland, grazed predominately by wool producing Merino …

Recent Advances In Stylosanthes Research In Tropical America, Bela Grof, Celso D. Fernandes, Jaqueline R. Verzignassi

IGC Proceedings (1977-2023)

The potential of neotropical savannas is very large for pasture-based livestock systems. There are 250 million ha of well-drained lowland savannas in the American tropics. Over 200 million ha are situated in the Cerrados region of Brazil. The Cerrados support 42% of the national herd. Although these ranges support large populations of livestock, productivity is generally low. Poor nutritive value of native pastures and monospecific swards of Brachiaria spp. is the principal cause of this low productivity, especially in the dry season when these grasslands often provide no more than 60% of the animal's maintenance requirements. The best option to …

Leucaena Production In Arid Botswana, F. P. Wandera, M. Karachi, S. Mangope, B. M. Lefofe Jun 2023

Leucaena Production In Arid Botswana, F. P. Wandera, M. Karachi, S. Mangope, B. M. Lefofe

IGC Proceedings (1977-2023)

The value of browse species as a source of nitrogen for grazing animals is restricted to wet seasons, with protein deficiencies being experienced by September (in dry winter season) in Southern Africa (Moleele 1998). This is when highly productive planted browse species would become useful to supplement the protein diet requirement of grazing animals (Morris & Du Toit 1998). Further, browse species can provide partly for protein requirement of intensive production systems, such as in feedlots and dairies. This paper reports work on the introduction and screening of Leucaena for Botswana conditions.

Ensiling Characteristics And Nutritive Value Of Browse/Maize Forage Mixtures, F. B. Bareeba, H. Kato, Elly N. Sabiiti Jun 2023

Ensiling Characteristics And Nutritive Value Of Browse/Maize Forage Mixtures, F. B. Bareeba, H. Kato, Elly N. Sabiiti

IGC Proceedings (1977-2023)

The practice of growing fodder tree and shrubs is being advocated for and adopted in smallholder dairy production systems. In Uganda, Calliandra calothyrsus, Gliricidia sepium, and Leucaena leucocephala have been identified and recommended as the most suitable species (Sabiiti, 2001). However tree foliage contains toxic compounds (Lowry, 1990), which may be alleviated by ensiling. The objective of the experiment was to study the ensiling characteristics of browse/ maize forage mixtures and their nutritive value when fed to lactating dairy cows.

Persistence Of Tall Fescue And Cattle Grazing Preference As Affected By Endophyte Status, D. J. Lang, S. P. Wang, A. Tokilita, R. Given, M. Salem, R. Elmore Jun 2023

Persistence Of Tall Fescue And Cattle Grazing Preference As Affected By Endophyte Status, D. J. Lang, S. P. Wang, A. Tokilita, R. Given, M. Salem, R. Elmore

IGC Proceedings (1977-2023)

Endophyte-infected (E+) grasses often exhibit increased survival, growth and resistance to herbivory compared to uninfected counterparts. Latch (1997) proposed a strategy for cultivar improvement of infecting elite cultivars with strains of Neotyphodium coenophialum that are non-toxic to livestock, but still able to convey the persistence advantage shown with wild-type, toxic endophyte. The strategy of re-infecting tall fescue (Lolium arundinaceum (Schreb.) Darbysh.) cultivars with naturally occurring, non-ergot-producing endophytes appears promising for removing animal toxicity symptoms and retaining agronomic performance (Bouton et al., 2002; Hill et al., 2002). The objective of this study was to compare the effect of …

Performance Of Animals Grazing Various Tall Fescue / Endophyte Combinations, Andrew A. Hopkins Jun 2023

Performance Of Animals Grazing Various Tall Fescue / Endophyte Combinations, Andrew A. Hopkins

IGC Proceedings (1977-2023)

Endophyte (Neotyphodium coenophialum) infection can improve tall fescue persistence (Read & Camp, 1986), but animals grazing wild type tall fescue often suffer from reduced performance and poor health (Hoveland et al., 1983). Novel endophytes do not produce the alkaloids implicated in animal toxicity and can help maintain stand longevity while minimizing animal health problems (Bouton et al., 2002). The objectives of this research were to compare productivity and health of animals grazing various tall fescue / endophyte combinations, and the persistence of these combinations under grazing in the Southern Plains of the USA.

Recovery Of Yearling Calves From Fescue Toxicosis, G. E. Aiken, M. L. Looper, S. F. Tabler, J. R. Strickland Jun 2023

Recovery Of Yearling Calves From Fescue Toxicosis, G. E. Aiken, M. L. Looper, S. F. Tabler, J. R. Strickland

IGC Proceedings (1977-2023)

Tall fescue (Lolium arundinaceum (Schreb.) S.J. Darbyshire) is widely utilized for grazing in the transition zone between the temperate and subtropical regions of the eastern U.S.A. Cattle grazing tall fescue frequently exhibit fescue toxicosis, a malady caused by consumption of toxins produced by the endophyte, Neotyphodium coenophialum. Symptoms of fescue toxicosis include retention of rough hair coat, increased body temperature and laboured respiration. Heat stress may be severe at onset of high ambient temperature and humidity. Transporting cattle exhibiting toxicosis can therefore be difficult because combined stresses of the toxicosis and transporting often result in high mortality. An experiment …

Reduce Tall Fescue Toxicosis In Festuca Arundinacea Forage Systems With Legumes, J. C. Waller, A. E. Fisher, H. A. Fribourg, C. J. Richards Jun 2023

Reduce Tall Fescue Toxicosis In Festuca Arundinacea Forage Systems With Legumes, J. C. Waller, A. E. Fisher, H. A. Fribourg, C. J. Richards

IGC Proceedings (1977-2023)

Tall fescue (Lolium arundinaceum = Festuca arundinacea) is an important cool-season grass because of persistence and spring and autumn productivity. Most existing tall fescue pastures in Tennessee are Kentucky-31 (KY-31) and are infested with the endophytic fungus Neotyphodium coenophialum that causes tall fescue toxicosis. Symptoms in beef cattle include reduced rates of gain, poor conception rates, decreased dry matter intake, a long rough haircoat in summer, and very low serum prolactin. Earlier studies indicated that the performance of cattle grazing endophyte-free (EF) tall fescue is superior to that of cattle grazing endophyte-infected (EI) tall fescue (Fribourg et al …

Milk Production From Cows Grazing Perennial Ryegrass Pastures Infected With Wild Or Ar1 Endophyte In New Zealand, Stephanie J. Bluett, E. R. Thom, D. A. Clark Jun 2023

Milk Production From Cows Grazing Perennial Ryegrass Pastures Infected With Wild Or Ar1 Endophyte In New Zealand, Stephanie J. Bluett, E. R. Thom, D. A. Clark

IGC Proceedings (1977-2023)

Most perennial ryegrass (Lolium perenne) cultivars in New Zealand are available with either the natural wild endophyte (Neotyphodium lolii); the AR1 novel endophyte (no lolitrem B or ergovaline production); or endophyte-free. Although wild endophyte protects ryegrass against insect attack, improving pasture persistence, it can also cause ryegrass staggers and reduced animal performance. Endophyte AR1 does not cause ryegrass staggers but still protects against insect pests such as Argentine stem weevil (Listronotus bonariensis). A 3-year farmlet experiment was carried out to evaluate the effects of AR1 and wild endophyte-infected ryegrass on pasture performance, milk production …

The Effects Of Exposure To Endophyte-Infected Tall Fescue Seed On Faecal And Urine Concentrations Of Ergovaline And Lysergic Acid In Mature Gelding Horses, C. L. Schultz, S. L. Lodge-Ivey, A. M. Craig, James R. Strickland, L. P. Bush Jun 2023

The Effects Of Exposure To Endophyte-Infected Tall Fescue Seed On Faecal And Urine Concentrations Of Ergovaline And Lysergic Acid In Mature Gelding Horses, C. L. Schultz, S. L. Lodge-Ivey, A. M. Craig, James R. Strickland, L. P. Bush

IGC Proceedings (1977-2023)

Despite the good nutritive value of endophyte-infected tall fescue, consumption by livestock results in a decrease in both reproductive and growth performance due to ergot alkaloids produced by an endophytic fungus (Cross et al., 1995). Little research has investigated the metabolic fate of ergot alkaloids and/or their metabolites in grazing horses. Thus, the objectives of this experiment were: a) to determine concentrations of ergovaline (EV) and lysergic acid (LA) in the faeces and urine of geldings exposed to tall fescue seed over a time course experiment and b) to measure the effects of alkaloid-containing tall fescue on nutrient digestibility …

Ergovaline And Ergovalinine And Tall Fescue Content Of Pastures In Central Kentucky, P. W. Long, Jimmy C. Henning, L. P. Bush Jun 2023

Ergovaline And Ergovalinine And Tall Fescue Content Of Pastures In Central Kentucky, P. W. Long, Jimmy C. Henning, L. P. Bush

IGC Proceedings (1977-2023)

Kentucky has > 2Mha of tall fescue (Festuca arundianacea Schreb.) grown mainly for livestock consumption. Many alkaloids in tall fescue are produced in a mutualistic association between tall fescue and an endophytic fungus (Neotyphodium coenophialum) (Long et al., 2002). Ingestion of tall fescue by livestock may depress reproduction and growth (Schultz & Bush, 2002). Not all Kentucky fields of tall fescue are thought to be infected with endophyte, but forage samples from all surveyed pastures had measurable ergopeptine alkaloids. Therefore, it is reasonable to assume that some of the tall fescue plants in these fields were infected. …

A Study In Cuba Of The Biology, Ecology And Agroecological Management Of Heteropsylla Cubana Crawford In Leucaena Leucocephala (Lam.) De Wit, N. Valenciaga, M. Felicia Díaz, T. E. Ruíz, M. Fernández, C. Mora

IGC Proceedings (1977-2023)

As a consequence of the increase in Leucaena leucocephala areas to counter the shortage of feed in Cuban cattle production, there is a risk of the development of Heteropsylla cubana Crawford (Hemiptera: Psyllidae) as a pest in silvopastoral systems with this legume. This psyllid is known to be the main phytophagous pest (Valenciaga, 2003), which produces damage in 95% of the apical region of branches. Since information on the identification and biology of a pest species is a necessary prerequisite for its management, a taxonomic, biological and ecological study was conducted to define Heteropsylla behaviour in Cuban conditions and elaborate …

Fodder Shrubs For Improving Incomes Of Dairy Farmers In The East African Highlands, Steven Franzel, C. Wambugu, J. Stewart, J. Cordero, B. D. Sande Jun 2023

Fodder Shrubs For Improving Incomes Of Dairy Farmers In The East African Highlands, Steven Franzel, C. Wambugu, J. Stewart, J. Cordero, B. D. Sande

IGC Proceedings (1977-2023)

Smallholder dairying is an important enterprise in the highlands of E Africa. Farm sizes average 1-2ha and zero-grazing, cut-and-carry systems predominate. Inadequate protein reduces milk production and forces many farmers to spend scarce cash on commercial dairy meal supplements. In 1991, on-farm trials on fodder shrubs were started in Embu District as a collaborative venture of the Kenya Agricultural Research Institute, the Kenya Forestry Research Institute, and the World Agroforestry Centre. Calliandra calothyrsus was released to farmers in 1995 and was followed by Leucaena trichandra, mulberry (Morus alba), and Sesbania sesban. Farmers produce seedlings of calliandra …

Stylo In India: Much More Than A Plant For The Revegetation Of Wasteland, C. R. Ramesh, S. Chakraborty, P. S. Pathak, Nagaratna Biradar, P. Bhat

IGC Proceedings (1977-2023)

Since the 1950s introductions of Stylosanthes scabra, S. hamata and S. guianensis from Australia, South America, the USA and Africa have continued in India. Although no cultivar has been released, selections of S. scabra, S guianensis and S. hamata are used in a range of environmental and commercial production systems. A large seed industry spanning >400 ha and run by >600 smallholder farmers producing 800t seeds/ year supports this usage (Rao et al., 2004). Stylo is mainly used in India for revegetation of wastelands where it reduces soil erosion and offers fodder for livestock (Pathak et al …

Leucaena In Northern Australia: A Forage Tree Legume Success Story, B. F. Mullen, H. M. Shelton, Scott A. Dalzell Jun 2023

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 Jun 2023

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.

Forage Quality Of Cool Season Pasture Species Under Two Rotational Grazing Height Regimes, H. D. Karsten, M. Carlassare Jun 2023

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.

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 Jun 2023

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 …

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 Jun 2023

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)

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 Jun 2023

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. …
