A Review Of The Impacts Of Invasive Wild Pigs On Native Vertebrates, Matthew T. Mcdonough, Stephen S. Ditchkoff, Mark D. Smith, Kurt C. Vercauteren
United States Department of Agriculture Wildlife Services: Staff Publications
The wild pig (Sus scrofa) is a successful invasive species that has become well established outside of its native range in Eurasia. The invasive wild pig is the result of released or escaped domesticated livestock becoming feral, or Eurasian boar introduced for hunting purposes. The global spread of wild pigs has recently been exacerbated in some areas, such as the USA, by anthropogenically assisted dispersal. Once established in novel ecosystems, wild pigs have the potential to have significant negative impacts on the ecosystem, and the scientific literature is replete with examples. It is generally accepted that wild pigs …

Natural grasslands on Southern Brazil comprise the so called “Rio de La Plata Grasslands” in South America. They are an important fodder source for ruminant pastoral systems and contribute to regional ecosystem services. Strength of these grasslands is its floristic diversity that poses a dilemma to farmers: how to choose management protocols that could be applied for hundreds of species. We propose to use a functional ecophysiological approach based on groups of grasses, the most abundant on aerial biomass of this natural grasslands. We clustered the most frequent grasses in two groups based on its leaf traits (leaf dry matter …

IGC Proceedings (1977-2023)
A green manure crop, sunn hemp (Crotalaria juncea L.), legumes, has a nematode-suppressive effect. It is also used as feed in India. However, it is not used as feed in Japan because it contains natural toxins: Pyrrolizidine alkaloids (PAs). PAs has the negative effects for not only livestock but also human health. The PAs, which are abundant in sunn hemp seeds and which are contained only slightly in leaves and stems. Therefore, if sunn hemp harvested before flowering, then no poison problem is posed by PAs. However, if it is harvested at the podding stage, a poisonous concentration of …

Adverse Events Reporting Of Clinical Trials In Exercise Oncology Research (Advance): Protocol For A Scoping Review, Hao Luo, Oliver Schumacher, Daniel A. Galvão, Robert U. Newton, Dennis R. Taaffe
Research outputs 2022 to 2026
Introduction: Adequate, transparent, and consistent reporting of adverse events (AEs) in exercise oncology trials is critical to assess the safety of exercise interventions for people following a cancer diagnosis. However, there is little understanding of how AEs are reported in exercise oncology trials. Thus, we propose to conduct a scoping review to summarise and evaluate current practice of reporting of AEs in published exercise oncology trials with further exploration of factors associated with inadequate reporting of AEs. The study findings will serve to inform the need for future research on standardisation of the definition, collection, and reporting of AEs for …

IGC Proceedings (1977-2023)
Available empirical and mechanistic models to estimate total dry matter intake (DMI) and pasture dry matter intake (PDMI) of grazing lactating dairy cows have mainly been developed under intensive grazing conditions. The objective was to evaluate the adequacy of such existent models for use under semi-extensive grazing conditions, characterised by semi-natural grassland and less intensive resource use. Feed intake of lactating cows was measured on three commercial organic dairy farms in South Germany during one or two 6-d-periods/farm in 2019. Each period, DMI was determined in 10 or 20 cows per farm from their daily faecal output measured using titanium …

Revisiting Nitrogen Fertilisation Rates Of Kikuyu And Kikuyu-Ryegrass Pastures, C. Viljoen, Janke Van Der Colf, Pieter A. Swanepoel
IGC Proceedings (1977-2023)
Irrigated pastures are used for dairy production in South Africa. Minimum-tillage and nitrogen (N) fertilisation are important management practices for kikuyu (Pennisetum clandestinum) and ryegrass (Lolium spp.) pastures. Nitrogen fertiliser application rates as high as 500 kg N ha-1 year-1 have been reported. Conventional tillage as well as cutting and removal of herbage material (opposed to removal through grazing) are the basis on which these fertiliser guidelines were developed. The current management practices have substantially changed the soil organic carbon and N stoichiometry. The aim of this study was to determine an optimum rate of …

Pasture Utilization At Islands In Northern Norway, V. Lind, Ø. Holand, F.-A. Haugen, G. Steinheim
IGC Proceedings (1977-2023)
The Norwegian sheep industry is based on utilization of “free” rangeland pasture resources. Use of mountain pastures is dominating, with about two million sheep grazing these pastures during summer. Regional challenges related to e.g., loss of sheep to large carnivores make farmers think differently. The Norwegian coastline is among the longest globally and is scattered with islets and islands. Alone along the coast of Nordland county, it is estimated more than 14,000 islands. Use of islands for summer pasture is an alternative but there is a limited knowledge about such a management system. In this study, we examined lambs’ average …

IGC Proceedings (1977-2023)
To effectively utilize locally available feed resources for dairy cattle in Africa, fermented total mixed ration (TMR) was prepared using Napier grass, corn meal, wheat bran, formula feed, and mineral and vitamin mix. The fermentation quality of TMR were analyzed after 14 days of ensiling. Before ensiling, aerobic bacteria were the dominant bacteria, after ensiling, lactic acid bacteria counts increased rapidly and became the dominant bacteria in TMR. After 14 days of ensiling, aerobic bacteria, coliform bacteria, yeasts, and molds showed lower (P < 0.05) counts in TMR than those before ensiling. The dry matter (DM) of TMR was adjusted to 45.50%, their crude protein and neutral detergent fiber contents were approximately 11.48, and 55.25% of DM, respectively. After 14 days of ensiling, TMR fermented to a good quality, the pH was reduced to 3.90; the lactic acid and ammonia nitrogen contents were 1.01 and 0.31% of FM, respectively; the propionic acid and butyric acid were too low to detect. The results confirm that fermented TMR prepared with local feed resources can attain a good quality in Africa.

The world grasslands/rangeland ecosystems comprise 26% of earth’s surface and have immense ecological and economic significance. Diversity of grasslands had been a key element for their sustainability. Grasslands in India have existed as natural ecosystems for millions of years. It is a major source of income, employment and livelihood to the rural families. Owing to heavy grazing pressure, coupled with other social/anthropogenic factors, the grazing resources have fast deteriorated. The country has many old and natural grasslands with ethnic and economic value. Comprehensive ecological studies including floristic compositions, dominant species, grazing pressure and the climax/sub-climax stages of ecological succession will …

More than two billion people globally still lack access to safely managed drinking water (WHO & UNICEF, 2021). Although gains in access to water service over the past two decades have been large, universal access to safe and affordable drinking water (SDG 6, target 6.1) is not on track to be achieved. In Panama, safely managed drinking water access has not been measured. However, the data on basic water access illustrates the large disparities between rural and urban areas of Panama. While 98% of urban Panamanian households have basic access to water, only 86% of rural Panamanian households, and 54% …

Auxin/Cytokinin Antagonistic Control Of The Shoot/Root Growth Ratio And Its Relevance For Adaptation To Drought And Nutrient Deficiency Stresses, Jasmina Kurepa, Jan A. Smalle
Plant and Soil Sciences Faculty Publications
The hormones auxin and cytokinin regulate numerous aspects of plant development and often act as an antagonistic hormone pair. One of the more striking examples of the auxin/cytokinin antagonism involves regulation of the shoot/root growth ratio in which cytokinin promotes shoot and inhibits root growth, whereas auxin does the opposite. Control of the shoot/root growth ratio is essential for the survival of terrestrial plants because it allows growth adaptations to water and mineral nutrient availability in the soil. Because a decrease in shoot growth combined with an increase in root growth leads to survival under drought stress and nutrient limiting …

Wild Red Deer Benefit The Conservation Of European Semi-Natural Open Habitats, F. Riesch, Bettina Tonn, Marcus Meißner, Sven Herzog, Niko Balkenhol, J. Isselstein
IGC Proceedings (1977-2023)
Traditional land use practices have shaped European landscapes for millennia. Agricultural intensification and declining popularity of pastoral farming in the past century have resulted in a tremendous loss of extensively used open landscapes and associated biodiversity. Today, conservation management needs to prevent secondary succession of many open habitats. Large or inaccessible target areas unsuitable for conventional conservation measures might benefit from grazing by wild herbivores, which do not require fencing nor regular welfare monitoring. In a military training area in Germany, we studied the quantitative and qualitative effects of wild red deer in two protected open habitat types (lowland hay …

Methane emission from livestock operation is an important source of greenhouse gas and contributes to global warming. Forage legume secondary compounds may mitigate methane emissions by reducing methanogenic population in the rumen. This study evaluated animal performance and methane emission from beef cattle grazing either a mixed pasture [Brachiaria brizantha cv. Marandu (palisadegrass) and Arachis pintoi (forage peanut) cv. BRS Mandobi] or a palisadegrass monoculture with or without nitrogen (N) fertilisation. A 2.5-yr continuous stocking experiment was carried out in southeast Brazil, on a randomized complete block design with three treatments and four replicates. Two Nellore heifers were used …

USU senior Connor has lived in the Uintah Basin all his life and studies kinesiology. Senior Casey, a Cache Valley native, studies climate science and works at the Utah Climate Center. Junior Bridger, also of Cache Valley, studies nutrition science. They led and funded this project through a student grant. Casey was alarmed by the ammonia data he was collecting at the Climate Center. “I immediately began to wonder how this issue would evolve over the coming decades.” The three teamed up to take a look at how Logan’s record-breaking amount of ammonia in our air is impacting those who …

Increasing yields in farmer fields is a priority to address increasing food demands. The study was conducted within four wheat-growing areas in Ethiopia: Debre Birhan, Hosaina, Sinana and Maychew. The objectives were to identify (1) best-bet soil fertility management options based on agronomic performance and economic evaluation and (2) key yield-reducing factors in farmer fields based on an agronomic survey among 55 participating farmers. Two types of on-farm experiments were conducted: researcher-managed trials that tested combinations of nutrients, including micronutrients, organic resources or both over two cropping seasons and farmer-managed trials comparing 'improved practice' against 'farmer's practice'. Fertilizer treatment affected …
