Nitrogen input in tropical pastures increases forage and animal productivity. Forage legumes can fix atmospheric nitrogen and are the most economical way to add this nutrient to the soil. Our objective was to report the benefits of forage legumes in tropical pastures and possible strategies to implement different forage legumes. In tropical conditions, such as in Brazil, the use of forage legumes is still scarce. Even with low legume adoption on tropical pastures, forage legumes can provide ecosystem services. Increased animal productivity is the first ecosystem service provided by these legumes, mainly due to the addition of nitrogen that is …

Ruminants are central to the economic and nutritional life of much of sub-Saharan Africa, but cattle are now blamed for having disproportionately large negative environmental impact through (amongst other things) emissions of greenhouse gases. However, the exact mechanism behind these emissions is not well-understood and indeed accurate estimates themselves are lacking due to a paucity of reliable data. Employing individual animal records obtained at regular farm visits, this study quantified emissions intensities (EIs) of smallholder farms in three counties of Western Kenya through life cycle assessment (LCA). Crude protein (CP) was chosen as the functional unit to capture outputs of …
Strategies For Assessing Grassland Degradation With Biogeochemical Models, S. Rolinski, S. B. Wirth, C. Müller, B. Tietjen
Strategies For Assessing Grassland Degradation With Biogeochemical Models, S. Rolinski, S. B. Wirth, C. Müller, B. Tietjen
IGC Proceedings (1977-2023)
Marginal grasslands provide the basis for livestock rearing and rural livelihoods globally, but are subject to permanent degradation from mismanagement and climate change. Global biogeochemical models are so far not able to represent degradation tipping points in marginal grasslands because plant growth is dependent only on bio-climatic conditions and nutrient availability. Due to their central role for sustaining livelihoods, this lack of representation in such models needs to be addressed. We present an idea on processes and interactions to be considered and on the actual implementation of necessary changes. The model for which we exemplarily develop implementation strategies, LPJmL, accounts …

IGC Proceedings (1977-2023)
Animal source foods (ASF) are essential for proper human development and function. Livestock in general, and ruminants in particular, are essential components of our sustainable global food systems. Of significant worldwide impact, diets with higher-than-recommended levels of ASF can correct the symptoms of metabolic illnesses, offering hope in arresting the current worldwide epidemic of diabetes and other metabolic diseases. Most dietary policy and recommendations are based on the ill-founded belief that plant-based, high-carbohydrate diets are “healthy.” High-quality scientific evidence does not support the belief that vegetarian diets are healthier than omnivorous or animal-based diets. A Therapeutic Carbohydrate Reduction (TCR) lifestyle …

Where Is The Livestock Future – Plate- Or Land-Based? The Potential Of Knowledge-Based, Holistic Grazing Concepts For Altering Grazing Livestock Systems, Juliane Horn, Johannes Isselstein
IGC Proceedings (1977-2023)
In those days, livestock production heavily depends on feed grown on arable land. Pork production needs most of arable land to gain one kilogram of human-edible protein, followed by chicken, beef production and the dairy sector. In many European countries there is a sharp decline in livestock grazing. Many dairy farms are under pressure to maximize the total annual milk output per cow resulting in increased herd sizes by occupying a minimum of land and feeding of conserved forage of silage and concentrates. Such practices reinforce the competition for arable land for animal feeding as well as grassland intensification by …

Assessing The Potential Of Diverse Forage Mixtures To Reduce Enteric Ch4 Emissions, C. Loza, S. Verma, S. Wolffram, A. Susenbeth, R. Blank, Friedhelm Taube, Ralf Loges, M. Hasler, C. S. Malisch
IGC Proceedings (1977-2023)
Enteric methane (CH4) is a main source of agriculture-related greenhouse gasses. Conversely, pasture is increasingly demanded by customers due to both perceived and real benefits regarding animal welfare, environmental aspects and product quality. However, if implemented poorly, CH4 emissions can increase, thus contributing to climate change. One promising option to reduce enteric CH4 emissions are plant specialized metabolites (PSM), and particularly tannins. Consequently, we conducted two complementary experiments to determine to what extent enteric CH4 emissions can be reduced, and how this affects milk yields: a) an in vivo experiment with grazing Jersey cows, where …

IGC Proceedings (1977-2023)
A recent advance using molecular biology has identified a transcription factor or master switch that can ‘turn on’ the condensed tannin pathway present in white clover, and with the appropriate promoters allows biologically significant levels of condensed tannin expression in leaf tissue. In vitro tests have demonstrated that the condensed tannins produced in white clover leaves can bind protein at a pH 6.5, as found in the rumen, and then release them at pH 2.5, the pH in the abomasum, before entering the small intestine for amino acid absorption. Additional tests have demonstrated that these condensed tannins can reduce methane …

IGC Proceedings (1977-2023)
The production of fodder beet (Beta vulgaris L.) in New Zealand is concentrated in the South Island, and often requires irrigation to achieve high yields. Development of efficient irrigation management strategies requires information on the effect of timing and rate of irrigation on crop growth. A field study was conducted on a moderately deep soil at Chertsey, Canterbury, New Zealand, to evaluate crop growth responses to five irrigation managements: Rain-fed (control), weekly replacement of full evapotranspiration (FullET-weekly), and 50% of evapotranspiration replaced weekly (HalfET-weekly), fortnightly (HalfET-2weekly) or 3-weekly (HalfET-3weekly). Irrigation to replace ET was adjusted to account for rainfall …

Maintain Forage Yields In Long- And Short-Term Grasslands In Norway, I. Sturite, T. Maeland, M. Höglind
IGC Proceedings (1977-2023)
Various reasons have been invoked explaining the low renovation activity in Norwegian grassland farming: swards are often located in marginal areas, ploughing and reseeding gives low or no yield in the renovation year, and it may be unprofitable to establish a new sward. The establishment of new leys can also prove difficult in seasons with unfavourable weather conditions. Thus, farmers prefer long-term or permanent swards as opposed to ploughed and reseeded swards. The hypotheses of this study is that under equal management conditions, permanent and temporary swards (leys) that are reseeded frequently are equally productive. We present results from an …

Comparison Of Four Maize Cultivars (Zea Mays L.) As Winter Forage In Sudan, Rihab El Zubair
IGC Proceedings (1977-2023)
Winter forage availability in Sudan is constrained by lack of a suitable annual winter forage crop. The main forage crop grown is Abu70 (Sorghum bicolor) which is a summer crop that yields 7.6-8.4 t/ha in summer but much less in winter. There is, therefore, need for a winter high yielding forage crop that exceeds Abu70 in productivity and quality. This study was aimed to evaluate four forage maize cultivars as potential winter crops in central Sudan in terms of productivity and quality. An experiment was conducted using four maize forage cultivars. The experiment lasted for two consecutive seasons …

Diet Selection By Goats At Kalemando, North Darfur, Sudan, Abdelrahim I. H. Mansoor, Babo Fadlalla
IGC Proceedings (1977-2023)
Pressure on rangelands of Sudan has increased in the last few decades due to increase in human population and in animal numbers. The rangelands were also impacted by climate change, desertification, agricultural expansion, mining, and overgrazing. Decreased amounts of rainfall have impoverished the natural rangelands. Goats are capable of grazing on semi-desert regions characterized by low rainfall and scarce grazing plants. It is therefore necessary to know and enhance plant species preferred by goats to properly manage the rangelands. The present study was conducted at Kalemando, North Darfur State during the rainy season of year 2017 when most plants were …
