Yield And Nutritive Value Of Heading And Headless Sorghum X Sudangrass Hybrids In Response To Cutting Frequency, J. K. Lee, H. S. Park, Y. C. Lim, S. Seo, B. H. Paek, J. H. Fike

IGC Proceedings (1977-2023)

Summer annual forages contribute greatly toward solving the problem of roughage supply for cattle in Korea. These forages support high levels of dairy and beef production during hot summer months when the quality and production of perennial herbage decreases due to unfavourable climatic conditions (Olson, 1971). This study investigated the effects of cutting frequency on dry matter (DM) yield and nutritive value of heading versus headless varieties of sorghum x sudangrass hybrid.

Rising populations and incomes in developing countries are likely to double demand for livestock products by 2020 (Delgado et al. 1999). This strong demand has potential to improve profitability for farmers but will require improved animal feeding in both semi-intensive crop-livestock and more extensive livestock systems. Forages usually are the most cost-effective option to supply feed demands, particularly for ruminant-, but also for pig- and poultry- production. It is critical to select the most suitable forages for the local system and conditions. Small- and even larger-scale farmers depend heavily on advice from extension and development agencies, and from seed …


Response Of Arachis Pintoi To Grazing Intensity When Associated With Different Grasses, C. M. S. de Andrade, R. Garcia, Judson F. Valentim, O. G. Pereira 2023 EMBRAPA, Brazil

Response Of Arachis Pintoi To Grazing Intensity When Associated With Different Grasses, C. M. S. De Andrade, R. Garcia, Judson F. Valentim, O. G. Pereira

IGC Proceedings (1977-2023)

Lack of legume persistence is one of the main reasons for poor utilisation of grass-legume pastures in the tropics. Arachis pintoi (forage peanut) is currently the most promising forage legume for the humid tropics, mainly because of good persistence under grazing (Grof, 1985; Fisher & Cruz, 1995). The objective of this work was to show how two accessions of A. pintoi react to increasing herbage allowance levels when associated with two different grasses.

Performance Of Dual-Purpose Cows On A Native Pasture-Arachis Pintoi Association In The Humid Tropics Of Mexico, E. Castillo-Gallegos, J. Jarillo-Rodríguez, E. Ocaña-Zavaleta, B. Marín-Mejía, L. 'T Mannetje, A. Aluja-Schunemann

IGC Proceedings (1977-2023)

Native grasslands (NG) are the main feed supply of dual-purpose (DP) cows of the Mexican humid tropics. NG comprise about 85% of Paspalum, Axonopus and Cynodon species, about 5% of native legumes, mainly of Desmodium, and the remaining 10% are narrow and broad leafed weeds. Arachis pintoi (AP) is a persistent grazing tolerant tropical legume. In association with sown grasses, it has improved dry matter (DM) yield, nutritive quality of forage, and milk yield up to 9 kg/cow/day (González et al., 1996). The objective was to determine if productive performance of DP cows could be improved by …


Production And Persistence Of A Native Pasture-Arachis Pintoi Association In The Humid Tropics Of Mexico, E. Castillo-Gallegos, L. 't Mannetje, A. Aluja-Schunemann 2023 CEIEGT, Mexico

Production And Persistence Of A Native Pasture-Arachis Pintoi Association In The Humid Tropics Of Mexico, E. Castillo-Gallegos, L. 'T Mannetje, A. Aluja-Schunemann

IGC Proceedings (1977-2023)

Arachis pintoi (Ap) is a highly persistent legume. This study aimed at: (i) determining if introducing Ap CIAT 17434 into a NG pasture affected its standing dry matter (SDM) and botanical composition (BC, %) and (ii) verifying if Ap would be as persistent as it is with introduced grasses (IG).


Variation Within The Species Macroptilium Atropurpureum Regarding Adaptation To Grazing, Cam K. McDonald, R. J. Clements 2023 CSIRO, Australia

Variation Within The Species Macroptilium Atropurpureum Regarding Adaptation To Grazing, Cam K. Mcdonald, R. J. Clements

IGC Proceedings (1977-2023)

The twining legume Macroptilium atropurpureum cv. Siratro was released around 1960 (Hutton 1962) and the rust resistant cultivar Aztec was released in 1994 (Bray & Woodroffe 1995). The species showed great potential for pastures in northern Australia and was planted over some 220 Kha in the 1960's and 70's. The species was high yielding and readily eaten by cattle. However, by the early 1980's the species had declined dramatically in grazed pastures. Clements (1989) showed that a major problem with Siratro was the frequency of removal of growing points. This leads to less regrowth after grazing, less seed set and …


Experiences With Establishing Legumes As Part Of A Ley Pasture In A Low-Input Farming System Of The Eastern Amazon, Brazil, S. Hohnwald, B. Rischkowsky, A. P. Camarão, J. A. Rodrigues-Filho, R. Schultze-Kraft, J. M. King 2023 University of Göttingen, Germany

Experiences With Establishing Legumes As Part Of A Ley Pasture In A Low-Input Farming System Of The Eastern Amazon, Brazil, S. Hohnwald, B. Rischkowsky, A. P. Camarão, J. A. Rodrigues-Filho, R. Schultze-Kraft, J. M. King

IGC Proceedings (1977-2023)

In the Eastern Amazon extensive pasture management by smallholders can result in degradation of grassland, leading to unproductive and abandoned agricultural areas (Dias-Filho, 2003). To avoid long and costly restoration of those areas, ley-systems with alternating cropping and pasture phases might offer a promising solution. The inclusion of N-fixing legumes is seen as a suitable method to improve soil fertility during the pasture phase. As mono-cultures seem not to be appropriate, given the phytodiverse climax vegetation in the humid tropics, a combination of various shrub and herbaceous legume species is proposed. Thus, this paper tests a grass-legume mixture to replace …

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 …


Enhancement Of Grassland Production Through Integration Of Forage Legumes In Semi-Arid Rangelands Of Kenya, P. N. Macharia, J. I. Kinyamario, W. N. Ekaya, C. K. K. Gachene 2023 KARI-Kenya Soil Survey, Kenya

Enhancement Of Grassland Production Through Integration Of Forage Legumes In Semi-Arid Rangelands Of Kenya, P. N. Macharia, J. I. Kinyamario, W. N. Ekaya, C. K. K. Gachene

IGC Proceedings (1977-2023)

Livestock production in semi-arid rangelands of Kenya is limited by the seasonal quantity and quality of fodder. Kirkman & Carvalho (2003) stated that these inter- and intra-seasonal quality and quantity fluctuations result in nutrient deficits that severely limit livestock production potential. The objective of this experiment was to study the effect of three forage legumes on the production of natural pastures in semi-arid rangelands of Kenya.


Desmanthus: A New Forage Legume To Improve Wool Growth In Tropical Australia, J. H. de A. Rangel, Carlos A. M. Gomide 2023 EMBRAPA, Brazil

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 …

Desmodium Velutinum: A High-Quality Shrub Legume For Acid Soils In The Tropics, R. Schultze-Kraft, M. Peters, N. Vivas, F. Parra, L. H. Franco

IGC Proceedings (1977-2023)

Drought tolerant legume shrubs can enhance the sustainability of smallholder production systems in the tropics through the provision, year-round, of high-quality feed and through their positive effect on soil. Desmodium velutinum (Willd.) DC. is one of the few shrub species that have been identified as (1) well adapted to acid tropical soils and (2) of good nutritive value (Schultze-Kraft, 1996). It is a perennial native to SE Asia and tropical Africa growing up to 3 m high, the velutinous (velvety) surfaces of its 1-foliolate leaves being a characteristic feature. It grows well on soils ranging from pH 4.0 to alkaline, …

Agronomic Evaluation Of Twenty Ecotypes Of Leucaena Spp. For Acid Soil Conditions In México, J. F. Enríquez-Quiroz, A. Hernández-Garay, A. R. Quero-Carrillo

IGC Proceedings (1977-2023)

Leucaena leucocephala Lam. (de Witt) has been shown to be a good forage producer and to posses good persistence under grazing conditions in México tolerating well the management of local cattlemen (Quero et al., 2004). The Leucaena genus is native to Central America and Mexico (Hughes, 1998), but L. leucocephala is a low producer under acid soil conditions. The natural diversity is a good source of resistance to acid soil conditions resistance and to other adverse factors. Several Leucaena accessions were evaluated for production under acid soil conditions in tropical Mexico.

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.

IGC Proceedings (1977-2023)

Grasses and tree leaves/shrubs are the major feeds available from grasslands and grazing fields. There is though a dearth of information on the nutritional value of tree foliage although available information was collated by Shelton et al. (1995). This study evaluated the relative nutritive value of two foliages for goats.


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

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.


The Effect Of Fermentation Of Calliandra Calothyrsus, Gliricidia Sepium, Leucaena Leucocephala And Maize Forage On Rumen Degradation And Microbial Protein Synthesis, H. Kato, F. B. Bareeba, Elly N. Sabiiti, C. Ebong 2023 Makerere University, Uganda

IGC Proceedings (1977-2023)

Ensiling as a means of storing green fodder by acidification has a profound effect on the chemical composition of the resultant silage. Ensiling could therefore, ameliorate the effects of anti-nutritional factors associated with browses. The objective of the experiment was to determine fermentation characteristics and rumen degradation (D) of ensiled Calliandra calothyrsus (C), Gliricidia sepium (G), Leucaena leucocephala (L) and maize forage.


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 2023 Mississippi State University

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 2023 Noble Foundation, Inc.

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 2023 Forage-Animal Production Research Unit

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 …
