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, …

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 …

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
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
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: Feeding “Hay” Without The Production Expenses, V. Baron, A. C. Dick, A. Omaha
IGC Proceedings (1977-2023)
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 …

IGC Proceedings (1977-2023)
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 …

Fodder Scenario And Hortipastoral Opportunities To Enhance Fodder Production In India, Nagaratna Biradar, C. Lakshmi Devi, Vinod Kumar, Narendra S. Kulkarni, G. K. Kumar Anil, S. S. Guledagudda, A. Bheemappa
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 …

Harvest Time Determine Biomass And Nutritive Value Of Forage Soybean In The Northwestern Loess Plateau Of China, An Dong, Jean Marie Vianney Nsigayehe, Y. Y. Shen
IGC Proceedings (1977-2023)
Soybean is a critical legume crop, which can be used as high protein forage in a crop-forage rotation system to supplement forage and increase system productivity. According to the actual production demand, selecting a suitable harvest time and the best feeding variety of soybean can provide a theoretical basis for applying forage soybean in a rotation system. In this study, four forage soybean varieties were selected in the Loess Plateau of northwest China. They were harvested on three dates suitable for local rotation conditions, and their biomass and nutritive value were evaluated. At the early harvest (20 August), the nutritive …

Developing A Simple Bioassay For Detection Of Alfalfa Autotoxicity In Field Soils, P. Baisley, K. Cassida, S. Gruss, E. Hill
IGC Proceedings (1977-2023)
Alfalfa autotoxicity causes yield reductions in alfalfa production by inhibiting plant establishment and decreasing plant productivity. Accurate predictions regarding autotoxic potential of the soil in a given field at a given time are an essential tool for alfalfa growers to make appropriate planting decisions. To address this issue, we are developing a soil bioassay that can be conducted as a mail-in soil test for alfalfa growers through plant diagnostic service laboratories. We hypothesize that we will detect differences in seed germination, emergence, root length, and root morphology between control and autotoxic soils. A preliminary trial testing alfalfa field soils and …

IGC Proceedings (1977-2023)
Permanent grasslands are the main food for livestock production systems in Southern Chile. Therefore, it is essential to develop management tools that optimize the use of pastures. Among these tools, the phyllochron could be a better method to control grazing frequency. The aim of this study was to determine the effect of three levels of soil pH, phosphorus (P) and nitrogen (N) on the phyllochron and growth dynamic of Lolium perenne and Bromus valdivianus. Nine monophytic mini-swards of each species were established in 125 L containers for three different pH, P and N levels. For one year we measured: …

Grazing Management For Alfalfa Persistence And Productivity In Warm-Climate Regions, D. Basigalup
IGC Proceedings (1977-2023)
Alfalfa is the most important cultivated forage crop in Argentina, where about 3 million hectares are grown. Even though the use of direct grazing is coming down during the last 15 years, it is still important for both beef and dairy production. Alfalfa grazing can play an important role in reducing operative costs and decreasing quality loss due to forage conservation (hay or silage). In this paper, the main concepts necessary to implement adequate and practical rotational grazing systems are briefly discussed. Particular attention is given to issues such as grazing frequency, grazing period, pasture use efficiency, and alfalfa quality …

Amphicarpic Legumes For Tropical Pasture Persistence, R Schultze-Kraft, A Schmidt, H Hohn
IGC Proceedings (1977-2023)
Amphicarpy, by which a plant produces underground seeds in addition to aerial fruits, is found in many plant families and in species of at least 15 legume genera. First studies on the tropical Centrosema rotundifolium and subtropical Macroptilium panduratum revealed for both species, besides their stoloniferous growth habit, two important mechanisms for survival under unfavorable conditions: (1) Underground meristems and reserve organs, and (2) regeneration from a soil seed reserve based on underground, aerial-flowering independent, seed production. Underground seed production was for both species particularly high on very sandy soils, but amphicarpy enables the plants to exhibit a plasticity response …

The Business Case For Healthy Grasslands-Based Agriculture – Economic And Social Implications, E. Bisangwa, Pat D. Keyser
IGC Proceedings (1977-2023)
Native perennial warm-season grasses (NWSGs) of the United States (U.S.) provide valuable summer forage. Studies have shown their potential within grazing systems as a complement to cool-season forages, as well as their benefits to soil biota, wildlife biodiversity, carbon sequestration and their resiliency to extreme drought and flood events. In this paper, we demonstrate that, in addition to these benefits, NWSGs provide important economic value to beef and dairy producers as a hedge against financial risks posed by overreliance on cool-season grasses.
Breeding Forage Grasses For Increased Heat Tolerance To Combat Climate Change, Eric D. Billman, J. S. Morrison, B. S. Baldwin
Breeding Forage Grasses For Increased Heat Tolerance To Combat Climate Change, Eric D. Billman, J. S. Morrison, B. S. Baldwin
IGC Proceedings (1977-2023)
The onset of climate change brings many challenges for forage production in the southeastern United States, where it is projected to become hotter and dryer in the next century. To combat this climatic challenge, recurrent phenotypic selection was conducted in growth chambers on annual ryegrass (Lolium multiflorum Lam.) and orchardgrass (Dactylis glomerata L.) to select seedlings that can germinate and survive at temperatures of 40°C. Following three cycles of selection, germination was increased from < 5% to 45% in annual ryegrass, and from 20% to 80% in orchardgrass. The rate of germination also increased, in both species by a factor of 8x that of the base germplasm. Realized heritability also increased by 40 – 45% for each species by the end of the project. This work successfully improved a quantitative trait using recurrent phenotypic selection using growth chambers as a stable environment and provided the basis for combatting climate change in other outcrossing forage species.
Industry Perspectives, Challenges, And Opportunities To Enhance Alfalfa In Warm Climates, J. H. Bouton
Industry Perspectives, Challenges, And Opportunities To Enhance Alfalfa In Warm Climates, J. H. Bouton
IGC Proceedings (1977-2023)
Alfalfa (Medicago sativa L.; aka lucerne) acreage is low in comparison to perennial grasses in warm humid regions. This includes the tropics and subtropics, and in the USA, the Southeastern states. The alfalfa seed industry therefore saw few reasons to target sales and marketing in these regions. This overlooked logical opportunities. In this paper, these opportunities are examined for Southeastern USA. The Southeast contains a majority of beef herd, a high percentage of the dairy herd, and millions of acres suitable for conversion to alfalfa. Alfalfa is also now viewed as the best crop to solve problems inherent with …

The Future Of Clovers In Forage Systems And As Cover Crops, J. H. Bouton, John R. Caradus
IGC Proceedings (1977-2023)
Clovers (Trifolium spp.) are the most widely used genera of legumes in forage systems, although only a limited number of the hundreds of perennial and annual species are commercially available. The number of varieties available within each of the main commercial species can be high and demonstrates past breeding achievements. Success relates to any clover’s ability to persist in mixtures with other forage species, across a range of soil types, management systems, and climates, while providing animal nutrition and biologically fixed nitrogen benefits. Uses range from traditional pasture mixtures with grasses to inclusion in multi-species mixtures, and as cover …

During the transition period between rainy and dry season, unfavorable climatic conditions such as limited water availability, temperature and light limit forage production and quality. Because of the seasonal pattern, it is essential to quantify forage mass for pasture management and planning purposes. The objective of this study was to evaluate Paiaguas herbage mass in pasture managed under continuous stocking with steers supplemented with protein concentrate offered in feed bunk and onground. The experiment was carried out in the Beef Cattle Facilities of Jatai Federal University (UFJ), from March to June 2020, in a completely randomized design, using 18 male …

This study investigated the effect of levels of artificial shading and harvesting age on four micro mineral concentrations (iron, manganese, copper and zinc) of Congo grass (Brachiaria ruzizinensis Germain & Evrard). The experiment was a 3 x 3 factorial arrangement in a split plot design with four replicates, which is three levels of artificial shading (0, 30 and 60% shading) as the main plot and three harvesting age (3, 6 and 9 weeks after cutback). The grass was established in May 2017 and grazed in 2018 and 2019, but a cutback was done in May 2020 for this study …
