The Effects of Multispecies Grazing on Pasture Management and Utilization
… between multiple grazing treatments and pasture utilization. The study was conducted for 60 days on the Western Kentucky University Farm in Bowling Green, KY. Cattle and goats have shown to differ in grazing preferences and to be economically important to the area. Grazing treatments …

Evaluation of perennial ryegrass cultivars for dairy production under different pasture management
… cultivars for dairy production under different pasture management. Five experiments were conducted in Canterbury, New Zealand to evaluate perennial ryegrass in terms of morphology (experiment 1), nutritive value (experiments 1 and 2), rumen degradation (experiment 3), dietary preference …

Effects of Stress on Several Immune and Health Responses of Weanling Calves
… to SVAREC were randomly assigned to 1 of 4 pasture management systems: 1) control (no treatment); 2) litter fed; 3) litter applied; 4) inorganic fertilizer; and 1 of 3 injection treatments (same as Trial 1). Whole blood Se and serum Cu increased post-stress and serum Zn decreased …

Asian long-horned tick distributions in Virginia pastures and evaluating the horn fly as a possible vector of Theileria orientalis Ikeda
… These findings suggest that fine-scale pasture management may be a viable tool for reducing tick populations. However, because T. orientalis outbreaks have been observed in regions with no or low tick density, investigating alternative transmission pathways is essential. To address this, …

Linking Conservation with Sustainable Mountain Livelihoods: A Case Study of Northern Pakistan
… of the local communities with resource management. However, this process of “new-commonisation” appears to be failing because it has not provided “a sense of ownership” among the local communities. To investigate the pertinent issues, this research encompassed five areas for analysis: 1) …

Nitrogen utilization in tall fescue (Festuca arundinacea Schreb.) pastures fertilized with nitrogen or grown with alfalfa (Medicago sativa L.) or red clover (Trifolium pratense L.)
… an alternative to nitrogen (N) fertilization in pasture management improves forage quality and animal performance and has been suggested to reduce the potential for environmental pollution. "Kentucky 3l" tall fescue fertilized with 160 kg N ha-1 yr-1 (split application) was compared to tall …

Paddock scale nitrous oxide emissions from intensively grazed pasture: Quantification and mitigation
… exchange of N₂O over an intensively grazed dairy pasture in New Zealand. The core of the work was based on eddy covariance (EC), a technique that allows measuring the N₂O exchange between the soil and the atmosphere at ten times per second. Since EC measurements of N₂O over dairy grazed land are …

The landscape ecology of brown hares and European rabbits in pastures in the north east of England
… may have been caused by changes in agricultural management. This study aims to identify hare distribution, density, habitat selection and demography in grasslands in order to benefit their future conservation. In addition, this study aims to investigate the impact of current agricultural …

Assessing Impacts of Winter-hay Feeding on Soil and Forage Nutrient Dynamics in a Rotationally-Grazed Pasture System in Arkansas
… rural land area was used for grazing (i.e., pastureland or rangeland) ruminant animals in 2017, constituting the largest private land use group. The expansive nature of these lands means that grazing and pasture management decisions have potential to impact water quality as well as profit …

Phosphorus Losses from Simulated Dairy Mangement Intensive Grazing Forage System
… the country are evaluating the effectiveness of management intensive grazing (MIG) systems as a means of reducing the economic pressures of confinement feeding and manure handling. Systems using MIG have been promoted as an environmentally safer way of managing nutrient balance on Center. …

Grazing management strategies of diverse pastures on irrigated dairy farm systems : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
… to improve DM production and quality are grazing management and the choice of forage species mixture. While grazing management rules are well developed, particularly timing and intensity, for perennial ryegrass-white clover pastures, the rules are less clear for diverse pasture mixtures that …

Effect of replacing nitrogen fertiliser with gibberellic acid on response of perennial ryegrass and white clover pasture : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
… nitrogen (N)-based fertiliser to achieve maximum pasture production due to the associated losses of N through nitrate leaching and nitrous oxide emissions. Gibberellic acid (GA), a naturally occuring phytohormone, has shown in short term studies, to increase, then reduce pasture yield when applied …

Climate change impacts and adaptation: a New Zealand dairy system : A thesis submitted in partial fulfilment of the requirements for the Degree of Master Master of Agricultural Science at Lincoln University
Pasture-based farming systems, as in New Zealand, are susceptible to changes in the climate through feed supply variability. Future climate change will likely alter pasture growth patterns, posing opportunities and risks that farmers will have to respond to and adapt to remain profitable. Due to …
