Forage Brassica Use In New Zealand And Australia Farming Systems, A. Dumbleton, H. G. Judson
IGC Proceedings (1977-2023)
Forage brassica, genus Brassica, are annual feed crops grown on farming enterprises throughout New Zealand and Australia. These crops provide a source of high-yielding, high-quality feed, which is particularly useful to complement pasture production during periods when pasture growth is reduced. There are six forage brassica species and subspecies of agricultural importance including bulb turnip, swede, kale, forage rape, leafy turnip, and raphanobrassica. All of these, as well as interspecific crosses and individual cultivars, offer a range of characteristics to fit various environmental and livestock production challenges. Consumption of forage brassica crops in ruminant animals may reduce methane emissions …

Fruit Forage Integrated Systems For Diversification And Other Ecosystem Services, S. Ahmad, N. H. Mir, S. S. Bhat
IGC Proceedings (1977-2023)
The interspaces (alleyways) in fruit orchards are generally not utilized for cultivation of perennial forage crops by a majority of farmers. These alleyways are often occupied by weeds or kept bare or clean with repeated tillage. The weeds may act as alternate/collateral hosts, thereby harboring pests and pathogens that may harm the fruit trees. In addition to this, the frequent tillage may subject the soil to erosion losses. Intercropping of perennial forage grasses and/or legumes with fruit crops is thus beneficial for not only providing high quality forage but also for providing various ecosystem services.Owing to an ever burgeoning population, …

History Of Endophytic Toxicosis And Novel Variety Solutions, J. H. Bouton
IGC Proceedings (1977-2023)
Associations of Epichloe endophytes with tall fescue [Lolium arundinaceum (Schreb). Darbush.] and perennial ryegrass (Lolium perenne L.) form the basis for the known science and ecology of mutualistic, fungal endophytes, and especially their impact on livestock. In the USA, millions of acres are endophyte infected today due mainly to planting ‘Kentucky 31’ to reduce soil erosion. Health problems emerged later among animals grazing the grass. These toxicity symptoms were listed under the general term ‘Fescue Toxicosis’. Research demonstrated that ergot alkaloids produced by the mutualism were mainly responsible. Developing endophyte-free versions of major varieties reduced host grass persistence …

Grazing Cover Crops In The Eastern Us: Performance Of Sheep, Goats, And Cattle Grazing Brassica Cover Crops, K. Cassida
IGC Proceedings (1977-2023)
Grazing annual forage crops has attained new interest with the increase in use of cover crops. Grazing annual forages grown as cover crops not only allows livestock producers to extend the grazing season but also gives row crop growers a way to recoup the cost of planting cover crops through grazing leases. Species in the Brassicaceae family (turnip, rape, kale, radish, and hybrids) have wide adaptability across the eastern US, excellent forage yield potential, and extremely high nutritional value. Brassicas are sometimes described as “high-moisture concentrates.” Their low effective fiber content drives the common recommendation to grow them with annual …

Extended Season Grazing On Two Ranches At Opposite Ends Of The Americas, Brett Chedzoy
IGC Proceedings (1977-2023)
Dormant season feeding of stored forages accounts for the majority of beef cattle production expenses across the world (Geiser and Boetel 2017). Additionally, most beef cattle production and particularly cow-calf operations are relegated to less accessible and productive landscapes, which reduces access to and increases costs for stored feeds. A comparison of two cow-calf operations owned and operated by the same family in the Province of Cordoba, Argentina and State of New York, USA are offered as case studies of creative solutions to these challenges. In Argentina, appropriate stocking for year-long grazing is the key to surviving the winter dormant …

IGC Proceedings (1977-2023)
Although necessary to maintain milk production in late lactation when grass is scarce, dependency on imported concentrate has negative environmental credentials; diversifying native feeds i.e., perennial ryegrass, using biorefinery, to produce high quality by-products may be a solution (Sanders et al., 2020). To validate these suggestions, a study was undertaken on dairy cows during the winter period; 60% of a perennial ryegrass silage diet was replaced with perennial ryegrass (PRG) press cake in treatment cows (GSPC; n=20), while a perennial ryegrass silage diet was offered to control cows (GS; n=20). Cows substituted with press cake produced 9.1 and 10.5 % …

Isoflavones In Legumes As Functional Forages And Feeds In Ruminant Grazing Systems, B. E. Davis, Michael D. Flythe, T. A. Hamilton, D. G. Ely, L. H. Anderson, J. R. Weinert-Nelson
IGC Proceedings (1977-2023)
Legumes are often utilized in livestock grazing systems to improve diet quality, diversity, and consequently animal performance. In addition to their nutritional utility, legumes contain phytoestrogenic isoflavones that have selective antimicrobial activity in the rumen and once absorbed can cause arterial vasodilation. These added bioactive functions of isoflavones suggest that legumes could be strategically utilized in grazing systems as functional forages to improve ruminant performance and health. The objective of this presentation will be to discuss past and current research on the application of isoflavones via legumes as an antimicrobial for growth promotion and as a mitigation strategy for fescue …

Cool-Season Annual Legumes And Forbs For Grazing And Cover Crop Systems, S. L. Dillard
IGC Proceedings (1977-2023)
Annual forage legumes and non-leguminous forbs can be used to interseed into perennial forage grasses or as a short-term grazing option between row crop rotations. Diversification of cropping systems by increasing number or type of cover crops in crop rotation plays an important role in improving land-use efficiency and in promoting sustainable agriculture. Legumes and other broadleaf forages provide increased forage digestibility and crude protein as a result of their greater leaf-to-stem ratio. In the Southeast U.S, few novel cultivars have been released in the last 20 years, resulting in the reliance on only a few forage cultivars and species. …

Animal And Forage Performance Of Integrated Crop-Livestock Systems, S. L. Dillard
IGC Proceedings (1977-2023)
Grazing of cool-season cover crops has been shown to be a viable tool for extending the grazing season while mitigating environmental risks associated with row-crop farming systems. Grazing cover crops is not novel, but most recent information available on this practice focuses on soil health as opposed to forage production and animal performance. Research has shown that forage quality of cool-season annual cover crops is sufficient to maintain an average daily gain of at least 1 kg/d and as high as 1.5 kg/d. Forage species selection plays an important role in the success of an integrated crop-livestock system. Grasses typically …

Swath grazing is a practice for overwintering beef cows on small grain forage left in the field to graze through snow, but annual variation occurs. The objective is to review 18 years of research at Lacombe, Alberta (AB) to describe how production attributes are related to cost mitigation and cow performance. Five trials compared swath grazing management options to pen-fed controls to determine feasibility. Associated studies monitored forage quality, soil fertility requirements and planting date impacts on yield. Mean, standard deviation, coefficient of variation, maximum and minimum values (n=18) for forage yield, pasture days, carrying capacity and percent utilization were …

Native warm-season grasses (NWSG) can produce high quality forage and high rates of gain for beef cattle. However, little data is available on how NWSG affect the productivity of cow-calf operations on a farm scale. Therefore, we implemented an experiment at three sites, Booneville, AR, Linneus, MO and Louisville, TN, with cow-calf pairs (mature cows over ≥ 3 years old, spring calving). We evaluated two forage systems that mix either a drought or drought/flood tolerant native C4 species [big bluestem (BB) blend or eastern gamagrass (EG)] with a cool-season perennial, tall fescue (TF), and compared them to the most …

IGC Proceedings (1977-2023)
Food grain production and livestock production are closely related in India as crop-residue forms the major source of fodder for livestock. It’s thus assumed that increase in food grain production has positive effect on availability of dry matter to the livestock. Using land use classification, crop production (2015 to 2020) and livestock census (2019) data, dry matter (DM) availability for livestock for 28 states of India was estimated. Hortipastoral opportunities by estimating area available under orchards in southern India were done to assess the possibility of introducing fodder crops in orchards. Some of the fodder crops were introduced in orchards …

Before the invasion of the fall armyworm (FAW) Spodoptera frugiperda into Africa, smallholder farmers had been using indigenous practices such as applying fish soup to plants to manage stemborer pests. Although farmers have since begun adapting this practice against FAW, no attempt has been made to scientifically evaluate this practice. Therefore, we assessed the efficacy of applying fish soup to maize plants that were artificially infested with FAW under semi-field conditions. Our results showed that foliar damage is inversely correlated with the concentration of a fish soup and sugar solution, with the highest (100%) concentration resulting in the lowest foliar …

Africa produces around 60% of the rice the continent consumes, relying heavily on rice imports to fulfill the rest of the domestic demand.Over the past 10 years, the rice-agricultural area increased nearly 40%, while average yield remained stagnant. Here we used a process-based crop simulation modelling approach combined with local weather, soil, and management datasets to evaluate the potential to increase rice production on existing cropland area in Africa and assess cropland expansion and rice imports by year 2050 for different scenarios of yield intensification. We find that Africa can avoid further increases in rice imports, and even reduce them, …
