IGC Proceedings (1977-2023)
The indigenous Lagune, a breed tolerant to trypanosomiasis, is an excellent candidate to meet the ongoing environmental changes sustainably. This cattle breed could be kept like small ruminants, tethered in grasslands, or free grazing. A study was conducted to assess the grazing behavior of Lagune cattle under the two grazing systems to identify the best systems for sustainable production and conservation of the breed. For this study, four Lagune cattle farms, 02 under free-roaming and 02 others in the tethered system, were selected in the original belt of the Lagune cattle, the agro-ecological (AEZ) zones of Valley and Pobe. The …

Stockpiling Perennial Warm-Season Grasses: Bermudagrass Example, J. A. Jennings, K. J. Simon
IGC Proceedings (1977-2023)
Winter feeding is the largest expense of maintaining a beef herd in terms of money and time. Stockpiled bermudagrass is an effective practice for reducing winter feeding expenses and extending the grazing season. Stockpiling forage is the practice of accumulating forage growth intended for grazing in a later season. In Arkansas, bermudagrass is stockpiled from early August to late October and is grazed from late October through mid-December. Rainfall during late summer can be erratic with high risk of drought stress, but an early start date maximizes the opportunity for acceptable stockpiled forage yield. Therefore, stockpiling bermudagrass should begin by …

Tall Fescue And Orchardgrass Productivity And Persistence Under Grazing Systems In Tennessee, K. Johnson, R. N. Oakes, G. Bates
IGC Proceedings (1977-2023)
The primary forage species used by cow-calf producers in grazing systems in Tennessee is tall-fescue. Tall fescue is considered an excellent cool-season perennial forage crop due to its high quality, production, and extended growing season. However, most of these tall fescue grazing systems are composed of tall fescue cv. Kentucky 31, which is known for containing a fungus endophyte that can be toxic to animals. Alternatively, orchardgrass is also a vastly used and important perennial cool-season forage in the United States. It can be used as a pasture, hay, and is a high-quality forage that is desirable for most livestock …

Leucaena Leucocephala As An Alternative Protein Supplement To Fishmeal For Small Holder Indigenous Lactating Cows In Bangladesh, M. A. S. Khan
IGC Proceedings (1977-2023)
In Bangladesh, locally produced fishmeal is being used as a protein source for lactating cows but sometimes it is scarce and expensive. There is a need for an alternative protein source such as a Leucaena species which can be grown by the roadside, embankment or in a small area close to home. An experiment was carried out to assess the effect on the performance of partially replacing fishmeal with fresh foliage from Leucaena leucocephalain the diet of lactating cows. Three diets containing (kg/day) urea-treated rice straw (11.0) with either fishmeal (0.25), fishmeal (0.15) and Leucaena (0.5), and fishmeal (0.075) and …

IGC Proceedings (1977-2023)
Integrated crop-livestock systems can potentially produce more product per unit of land with minimal impacts on soil health and cash crop quality. In the Upper Midwest there is an opportunity to graze fall cover crops (CC) after winter wheat in a corn-wheat rotation. In East Lansing, Michigan, two CC treatments: 1) a pure brassica mixture (PURE), and 2) a complex mixture containing legumes, warm and cool season grasses, and brassicas (MIX) were planted after wheat, and grazed by lambs in the fall seasons of 2019 to 2021. The following year, soil health, corn yield and quality were measured from plots …

IGC Proceedings (1977-2023)
Agrivoltaics production systems have gained traction globally, holding promise to supply energy and food concurrently from the same unit of land. Studies investigating shade tolerant crops to optimize production under solar panels have mostly followed the findings of agroforestry studies. However, spectral composition of transmitted radiation in agrivoltaic and agroforestry production systems may not be the same, inducing different shade responses of understory crops. A pot trial investigating the effect of shade source on biomass production and morphology of perennial ryegrass, ribwort plantain and white clover was established during spring, in Oregon, USA. Treatments were solar panel shade, hazelnut tree …

Bale Grazing: Feeding Hay On Pasture Using Rotational Grazing Techniques, Greg Halich
IGC Proceedings (1977-2023)
Bale grazing is a novel winter-feeding method where bales are set out on pasture, typically in checkerboard fashion, and fed in a planned, controlled manner, much like rotational grazing. So far, the concept has not been widely adopted in the eastern US, but offers an improved alternative compared to conventional winter-feeding systems for beef cattle, which all too often results in wasted nutrients, polluted waterways, degraded soils, and unhealthy conditions for cattle. With good management, bale grazing can solve all of these problems, and also requires less labor and machinery use than conventional hay feeding. However, climatic conditions in the …

More Than Fiber: Forage Carbohydrates Affecting Animal Performance, M. B. Hall
IGC Proceedings (1977-2023)
Forages are well known as an important source of fiber in livestock diets. However, their carbohydrate contribution is more than fiber. Forage grasses and legumes supply sugars, fructans, and other water-soluble carbohydrates as well as soluble fiber that behave very differently than starch in the rumen. With a focus on ruminants, we will explore the forage supply, and ruminal and animal impacts.

Extending The Grazing Season Through The Use Of Cover Crops, D. D. Harmon
IGC Proceedings (1977-2023)
The use of cover crops in integrated crop-livestock systems is not a novel approach but has increased in popularity over the last few years due to the renewed interest in soil conservation, nutrient cycling, and water conservation. Moreover, cool-season annual forages have the ability to extend the grazing season, reduce the need for stored or bought supplemental feedstuffs, and as a result, lower winter-feeding costs. Small grain cover crops, legumes, forbes, and annual ryegrass (Lolium multiflorum Lam.) vary in their growth distribution and can be planted alone in monocultures or planted in mixtures to take advantage of the individual …

In Vitro Methane Production From Heifers Offered Four Bermudagrass Cultivars, A. R. Hines, W. G. Bergen, M. K. Mullenix, S. L. Dillard, T. R. Callaway, W. B. Smith
IGC Proceedings (1977-2023)
Though bermudagrass (Cynodon dactylon [L.] Pers.) is one of the predominant warm-season perennial forage supporting the southeastern United States livestock production systems, little is known about its influence on parameters of ruminal metabolism, including carbon loss as methane. With the multitude of cultivars of this grass that have been developed and released, one may question whether the physiological cultivar differences will manifest varying results in digestive efficiency and subsequent methane emissions. Thus, the objective of this study was to evaluate in vitro methane (CH4) production as influenced by four bermudagrass cultivars. Ruminally-fistulated heifers (n = 4) were assigned randomly …

Adoption Of Plantain Within New Zealand Farming Systems, Michael B. Dodd, J. B. Pinxterhuis, P. Hedley, L. Keenan, A. Duker, A. Moorhead
IGC Proceedings (1977-2023)
In New Zealand, plantain has been incorporated into the pasture forage base in three ways: as a short-term pure crop; as a major component in “herb mixes” that include clovers and chicory; and as a minor component in perennial grass-based swards. All types are typically grazed in-situ. Given the incentive to optimise the plantain proportion in livestock diet to mitigate nitrogen losses and the observed lack of persistence in grass-dominant pasture over time, there is a need to use various pasture types strategically across a farm system to ensure a long-term sustainable contribution of plantain to feed intake. The inclusion …

Can You Have Your Cake And Eat It Too? Impact Of Grazing Cover Crops On Soil Properties, M. E. Drewnoski
IGC Proceedings (1977-2023)
Does grazing of cover crops negate the soil health benefits of cover crops (CC)? A review of the literature was conducted to understand the soil impacts of grazing CC compared to a non-grazed CC control. Grazing CC did increase soil compaction in 50% of cases, but this increase was below the threshold that would be expected to impact root growth in most cases. It does appear that grazing under wet soils or high stocking rates can compact soil. Grazing did not affect wet aggregate stability in 83% of the studies. Soil carbon concentration was unaffected in 70% of the studies …

IGC Proceedings (1977-2023)
Integrated crop-livestock systems (ICLS) can bring numerous benefits to crops or livestock systems, such as increase soil C sequestration, farm profitability, and provisioning of ecosystem services. In a changing world, production systems need to become more resilient and sustainable. Specialized agriculture is characterized by a high level of inputs and outputs, and oftentimes specialize in a single crop to simplify management. However, such operational systems stray away from sustainable standards. Furthermore, specialized cropping systems may face problems such as persistence of pests and diseases, loss of biodiversity, stagnant yields, development of herbicide-resistant weeds, soil erosion and consequently loss of soil …

Strategic Integration Of Grasslands Within The Agricultural Landscape: Optimizing Benefits For The Producer And Society, A. J. Duff, J. G. Franco
IGC Proceedings (1977-2023)
We provide a case study assessment, centered in the Upper Midwest region of the United States, of the economic and environmental outcomes associated with the inclusion of grasslands within dairy production systems. This farmscape design approach can be applied at farm, watershed, and regional scales, and has the potential to significantly improve the resilience of our agricultural lands. Ruminant livestock are uniquely adapted to utilize perennial forages, and the strategic integration of grasslands within the agricultural landscape can improve producer return on investment while generating ecosystem services that benefit the production system and society.
