Proper nutrient management is key to maintaining high yields, quality, and stand longevity for profitable alfalfa production. By the time that visible symptoms of nutrient deficiencies have appeared, yield, quality, and economic losses have already occurred. Soil tests provide a proactive opportunity to prepare fertilizer or amendment supplementation before the growing season. Fertilizer applications can greatly improve crop yield and quality and, in turn, greatly increase economic returns.

We investigate JN.1-derived subvariants SLip, FLiRT, and KP.2 for neutralization by antibodies in vaccinated individuals, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected patients, or class III monoclonal antibody S309. Compared to JN.1, SLip, KP.2, and especially FLiRT exhibit increased resistance to bivalent-vaccinated and BA.2.86/JN.1-wave convalescent human sera. XBB.1.5 monovalent-vaccinated hamster sera robustly neutralize FLiRT and KP.2 but have reduced efficiency for SLip. All subvariants are resistant to S309 and show decreased infectivity, cell-cell fusion, and spike processing relative to JN.1. Modeling reveals that L455S and F456L in SLip reduce spike binding for ACE2, while R346T in FLiRT and KP.2 strengthens …

Osteosarcoma is the most common primary bone malignancy in children and young adults, and it has few treatment options. As a result, there has been little improvement in survival outcomes in the past few decades. The need for models to test novel therapies is especially great in this disease since it is both rare and does not respond to most therapies. To address this, an NCI-funded consortium has characterized and utilized a panel of patient-derived xenograft models of osteosarcoma for drug testing. The exomes, transcriptomes, and copy number landscapes of these models have been presented previously. This study now adds …
A New Look At The Debate Between Confucian Soft-Power And Legalist Hard-Power Statecrafts And Its Contemporary Significance, Shirong Luo
Comparative Philosophy
In recent years, comparative scholars and commentators have attempted to find ways to best characterize the opposition between Confucianism and Legalism. For example, it has been argued that Confucianism exemplifies “idealism”, whereas Legalism is a version of “realism” and that their dispute can be construed as a clash between the broader philosophical frameworks of idealism and realism. While casting these opposing political philosophies as such can shed some light on the differences between the two schools of classical Chinese philosophy, these conceptual labels are too broad to capture their fundamental differences, which in my view are their different understandings of …

From Contemplation To Counseling: Exploring Philosophical Practice By Constructive-Engagement Strategy Of Comparative Philosophy, Xiaojun Ding, Chao Yang, Peter Harteloh, Feng Yu
Comparative Philosophy
This paper applies Bo Mou’s Constructive-Engagement Strategy of Comparative Philosophy (CESCP) to explore philosophical practice as a novel paradigm that applies philosophy to everyday life. The study advocates for a transformative methodology that seeks truth through critical engagement, joint contributions, and diverse methodological tools, advancing the discipline towards a comprehensive world philosophy. Philosophical practice, characterized by its engagement with human experience and existential inquiries, integrates Eastern and Western philosophies to guide individuals in the art of living. It offers a philosophical alternative to psychological counseling, focusing on reasoning to address life’s challenges and ethical dilemmas. The paper examines the integration …
A Realist Daoism: Reading The Zhuang-Zi With Lao Zi's Daoist Realism, Wai Lok Cheung
A Realist Daoism: Reading The Zhuang-Zi With Lao Zi's Daoist Realism, Wai Lok Cheung
Comparative Philosophy
A realist Daoism is best illustrated through contrasting with something less robust. Chad Hansen’s Daoism may be understood as a linguistic constructivism and is thus a good candidate. I challenge his interpretation of the Zhuang-Zi and respond with a realist understanding of daos. The resultant realist Daoism is to be understood given a Daoist realism from Lao Zi’s Dao-De-Jing, whose realist flavour is constituted by some dao sometimes, if not always, outrunning us. The present paper thus situates Zhuang Zi better as inheriting Daoism from Lao Zi, contributing to classical Daoism with a relativity …

Foraging Strategies Of Ruminant Livestock On Intensively Managed Grasslands: Potential And Constraints, I J. Gordon, C Lascano
Foraging Strategies Of Ruminant Livestock On Intensively Managed Grasslands: Potential And Constraints, I J. Gordon, C Lascano
IGC Proceedings (1977-2023)
All grazed swards exhibit heterogeneity in the spatial (horizontal and vertical) dispersion of species/biomass. A herbivore foraging at random within such a heterogeneous environment would ingest less nutrients than wou Id one which exploited the heterogeneity on offer through selective grazing. The suite of decision-making processes involved in the selective grazing we observe is termed the animal's foraging strategy. On first observation, intensively managed sown swards appear to offer little opportunity for a herbivore to exhibit a foraging strategy; however, opporlunities do exist and there is empirical evidence that herbivores foraging on sown swards tend to have a diet higher …
Comparative Foraging Strategies Of Grazing Ungulates In African Savanna Grasslands, N Owen-Smith, D H.M Cumming
Comparative Foraging Strategies Of Grazing Ungulates In African Savanna Grasslands, N Owen-Smith, D H.M Cumming
IGC Proceedings (1977-2023)
We review the evolutionary (species-specific) and ecological (individual behavioural) strategies of African grazing ungulates. The contexts considered are free-ranging wild ungulates, traditional livestock pastoralism and extensive commercial ranching. Particularly successful are (1) buffalo, able to digest grass fibre effectively in mesic grasslands; (2) wildebeest, exploiting semi-arid grasslands through migration; (3) megaherbivores (elephant, hippopotamus and white rhinoceros) utilising a wide range of vegetation components. Species-specific adaptations include body size and metabolic rate, digestive efficiency and passage rate, oral and dental anatomy, water dependence and detoxification capacity. Species overlap in grass species se'lected, with dietary differences apparent in grass height favoured, and …
Comparison Of Animal Gains Using Perennial Pastures Exclusively Or Combined With Chicory-Oats-Clover Temporary Winter Pastures, J A. Josifovich
Comparison Of Animal Gains Using Perennial Pastures Exclusively Or Combined With Chicory-Oats-Clover Temporary Winter Pastures, J A. Josifovich
IGC Proceedings (1977-2023)
The increment of winter forage availability using short-rotation pastures could be an interesting way to increase winter carrying capacity. The producer could make good use of higher spring grass production. Sowing oats, rye or chicory alone is quite common in the Argentine Pampa. to evaluate the efficiency of these short-rotation winter pastures a 3 year trial was carried out at Pergamino Experiment Station. The treatments were: a) perennial pastures, 100% of the surface, b) perennial pastures 75%, and chicory-clover 25%, with 2 replications of 3 ha each. The pastures were, for. class II soils, fescue (Festrlca aru11dinacea Schreb.) cv. El …

Influence Of Climatic Factors On Animal Production In The Humid Pampa Of Argentina, J D. Josifovich, E Frutos
IGC Proceedings (1977-2023)
For any' pasture grazing area it is important lo know the relationship among the climatic parameters, rainfall and temperature, with carrying capacity and minimal gains. The availability of pasture to adjust stocking rates and make provisions for hay or supplementary feed needed for periods of shortage can be estimated from these data. Seven years of monthly rainfall and medium average temperature; and 25 years of forage digestibility and average daily gains were related to cattle i: carrying capacity; Analysis was made using the stepwise regression method. Carrying capacity was evaluated considering animal units (AU) for a 400 kg head gaining …
A New Theory Of Feed Intake Regulation In Ruminants And Its Implications For Forage Quality Research, J.J M.H Ketelaars, B J. Tolkamp
A New Theory Of Feed Intake Regulation In Ruminants And Its Implications For Forage Quality Research, J.J M.H Ketelaars, B J. Tolkamp
IGC Proceedings (1977-2023)
The low voluntary intake of many roughages is commonly explained by a limited physical capacity of ruminants to process fibrous feeds. Recently, we developed a new theory of feed intake regulation assuming feed consumption to create both benefits for the animal (represented by the intake of net energy for maintenance and gain) and costs (represented by the total oxygen consumption of the feeding animal). For nonreproducing ruminants we have shown that voluntary intake of roughages is close to the optimum feed intake level, i.e., the level at which for the animal the ratio between benefits and costs becomes maximum. According …
A Conceptual Model To Explain Variation In Ingestive Behavior Within A Feeding Patch, Emilio M. Laca, M W. Demment, R A. Distel, T C. Griggs
A Conceptual Model To Explain Variation In Ingestive Behavior Within A Feeding Patch, Emilio M. Laca, M W. Demment, R A. Distel, T C. Griggs
IGC Proceedings (1977-2023)
A conceptual model is presented that links the mechanics of bite formation to the characteristics of the sward to explain variation in bite weight, bite area, bite depth and biting rate measured in a series of experiments with hand-constructed swards. Bite area is determined by the behaviour used by the animal to collect and grasp the tillers, and the length and stiffness of the sward, Bite depth is affected by height and the degree of vertical heterogeneity in stiffness. Time per bite is controlled by bite weight. These mechanisms of bite formation and time per bite ex.plain many observed effects, …

Selective Behaviour Of Cattle Grazing Ryegrass Swards With Horizontal Heterogeneity In Patch Height And Bulk Density, Montague W. Demment, R A. Distel, T C. Griggs, E A. Laca, G P. Deo
IGC Proceedings (1977-2023)
Patches of different height and/or bulk density were created in ryegrass pasture to study selective responses of steers to horizontal variability in patch structure. The experiment involved 3 heterogeneity treatments with 2 patch types each. Steers encountered and entered both patch types available in each treatment with the same frequency. In contrast, they grazed for a longer time (T,) at; and removed more bites (B) from the patch type that yielded greater intake rates. While T, and B varied for a patch type depending on the alternative patch, bite rate and likely bite size were constant for a given patch …

Computer Recording Of The Variation In Intake Of Supplements Provided To Grazing Cattler, R M. Tait, L J. Fisher
IGC Proceedings (1977-2023)
A computer system has been developed to record the consumption of' supplements provided free choice to grazing cattle. The system is based on electronic animal identification and one or more weatherproof electronic scales located in simple feed stations connected by telephone cable to a computer at a distance of up to 1 km. The software program identifies and records individual animals, • time and duration of visits, and the quantity of supplement consumed. The system has been tested in the field using 40 kg molasses-based feed blocks with up to 20 steers per feed station in paddocks of approximately 4 …

Comparison Of Bite Weight And Bite Dimensions Of Sheep And Goats Grazing A Range Of Grasses And Clovers, Y Gong, J Hodgson, M G. Lambert, A.C P. Chu, I L. Gordon
IGC Proceedings (1977-2023)
Response patterns in bite weight and bite dimensions of sheep and goats were evaluated using 3 grasses and 3 clovers sampled at 2 stages of maturity offered as prepared turves to animals confined in metabolism crates. Average bite weight across 12 sward types (6 forages x 2- stages) was similar for sheep and goats, but goats had greater bile weight per unit LW0•75 tlian sheep, Despite being shorter, the much denser clover swards resulted in larger bite weight than did grass swards. The taller reproductive swards enabled animals to harvest greater bite weights than did vegetative swards. Sheep obtained heavier …

Relationship Between Sward Structure And Dietary Quality And Intake, In Cattle Grazing Humid Sour Grassveld In South Africap, P J. O'Reagain, M Haller, P.J K. Zacharias
IGC Proceedings (1977-2023)
The relationship between sward structure, and dietary quality and intake was investigated for cattle grazing humid sour grassveld in south Africa. A 2-ha site was divided into 6 equal-sized blocks with; each block being managed to achieve a different sward structure using rotation·a1 grazing of cattle at 3, 5, 8, 11, 16 or 20 week intervals. Before to grazing, sward structure was quantified in terms. of tuft height, leaf table height, stemminess and greenness of the 3 most abundant species as well as sward leaf density. Oesophageal i fistulates were used to estimate dietary quality, bite rate, bite size, and …

Bite And Bolus Size Of Japanese Black Cattle Grazing Trays Of Perennial Ryegrass Of Different Heights, Shigeru Shioya, Kazuhiko Ochiai, Yasuko Togamura, K Betteridge
IGC Proceedings (1977-2023)
To determine the influence of grass .height on ingestive behaviour of Japanese Black cattle, bite size and bolus size of a Japanese Black heifer (230 kg body weight) and a Japanese Black cow (450 kg body weight) were estimated on perennial ryegrass (Lolium pere,me L.) turfs. Turfs in trays (460x600xl00 mm) were fed to the cattle for up to 3 min and reductions in turf weight were measured. One high (25 cm), 2 medium (13 cm) and 2 low (6 cm) turfs were offered to each animal. Bite size (dry matter intake/bite) both for the heifer and cow was greatest …
Performance Of Subterranean Clover Int He Central Andes Of Peru, Brigitte L. Maass, Custodio L. Bojorquez
Performance Of Subterranean Clover Int He Central Andes Of Peru, Brigitte L. Maass, Custodio L. Bojorquez
IGC Proceedings (1977-2023)
The central Andes of Peru are characterised by moderately acid soils, a pronounced dry season of 4-5 months and temperatures that decrease as night frosts increase with altitude. Above an altitude of 3200 m asl, the proportion of pastures in land use increases. However, native pastures lack sufficient quality and quantity to maintain· animal production, particularly in the dry season. Where irrigation is not available, introducing annual legumes may be an option to improve native pastures. In a trial to test adaptation of subterra.nean clover (Trifolium subterraneum L.), 5 Australian cultivars were sown at 4 different altitudes between 3300 …
Rangeland Exploitation- The Global Need For Integrated Science, A H. Nordmeyer
Rangeland Exploitation- The Global Need For Integrated Science, A H. Nordmeyer
IGC Proceedings (1977-2023)
The global surge in human population growth is placing major pressures on winter cold rangelands. The need is urgent to develop an international science that comes to grips with local requirements for food and fuel, and combines these with the global requirements of maintaining and increasing stores of carbon. The critical problem for rangelands is that most systems do not generate incomes to allow replacement or enhancement of the nutrients removed by herded animals, by cut-and-carry forage harvesting, and by fuel extraction. Progress in rangeland science that is relevant to subsistence cultures requires a better understanding of the carbon and …

A Computer Model For Determining When To Start Spring Grazing, Dennis R. Buckmaster, Warren J. Parker
IGC Proceedings (1977-2023)
A simple computer model is presented for determining the earliest grazing date after winter freezing. The model also illustrates principles of rotational grazing management and projects when forage should be conserved during the spring. Inputs to the model include initial herbage cover, herbage growth rate, herbage quality, a post•grazing residual dry matter target, a harvest set•aside threshold, and a description of the grazing animals.
Use Of A Simple Model Of Continuous And Rotational Grazing To Compare Herbage Consumption, Simon J.R Woodward, G `C Wake, D G. Mccall, A B. Pleasants
Use Of A Simple Model Of Continuous And Rotational Grazing To Compare Herbage Consumption, Simon J.R Woodward, G `C Wake, D G. Mccall, A B. Pleasants
IGC Proceedings (1977-2023)
A simple mathematical model (a linear dynamical system) was constructed to predict herbage consumption by grazing animals. This model was used to compare 3 grazing methods over a range of stocking rates at low pasture mass. The grazing methods compared were: continuous grazing (CTS), rotational grazing with equal time intervals (BQ), and rotational grazing where the time of shift was optimal for maximising intake (OPT). The rotational methods were the simplest possible, the land being subdivided into 2 fields, each of which was grazed once. The order of grazing the fields was also considered. The model predicts (I) that at …

Old Mr. Kroupa Had A Farm, Eieio: Establishing A Liberty Interest In 4-H Participation In Kroupa V. Nielsen, 731 F.3d 813 (8th Cir. 2013), Steven A. Rodgers
Southern Illinois University Law Journal
In Kroupa v.
