AbstractExtended grazing is a management system in which the usual grazing season is lengthened by utilization of hay fields for pasture. Extended grazing systems are a low-input alternative to conventional systems to the extent that they decrease the reliance on inputs such as machinery and energy to harvest forage. Substituting pasturing for harvested forage can therefore potentially decrease production costs and enhance the profitability of livestock production. However, the farm-level economic impacts of such a substitution are not well known. This analysis quantifies these impacts for beef cow/calf production. Specifying alternative meadow management systems for different grasses and using an economic-engineering approach, we have found that extended grazing can be a more profitable option for cow/calf production. Other findings suggest that, in an extended grazing system, the type of meadow, the hay baling method and the associated hay spoilage level also have important effects on production costs and profitability.

The introduction of a quality management system is important because it leads to improved productivity, optimization of business processes of the organization, and also leads to a reduction in production costs. The article considers the theoretical aspects of the quality management system at the enterprise, outlines the methods and classification of existing quality management systems. The essence of legal regulation of the quality management system is investigated and its current state is characterized. It is noted how some experts classify quality management methods. Recommendations for improving the quality management system at a domestic enterprise are offered. Emphasis is placed on the fundamental standards of ISO 9000 and how they are integrated into the state standards of Ukraine. When developing quality management systems, it should be borne in mind that the quality management system covers all processes that occur in the enterprise and on which the quality of products or services depends. According to the capabilities of the production process, the stages of the product life cycle are considered, which should be used at the appropriate stages of development and certification of the quality management system. The task of improving the quality and expanding the range of products is relevant in modern production conditions. This task is multifaceted and includes a number of scientific and technical, environmental, economic and social problems. An interdisciplinary approach is needed for an effective solution. One of the ways is product quality management based on assortment analysis and its innovative development. The experience of developed countries shows that the health of the nation, primarily through food, their safety, is more reliable when it is achieved by improving the quality of products based on standardization worldwide and internationally. At the international level, quality requirements are regulated by ISO standards, strictly focused on the consumer. The first such standards were the standards of the 9000 series, which came out in the late 80's pp. XX century More than half of the world's countries have implemented national standards identical to ISO standards, as well as certified enterprises in accordance with ISO standards.

The intensification of livestock production has highlighted the importance of balancing production and the environmental impact in grazing systems. With the advent of more distributed computing power we have seen more complex models being developed, capable of simulating most aspects of a livestock production system. Where the modelling objective includes prediction of both productivity and environmental impacts, it is imperative to include appropriate consideration of the grazing animal in the simulation. This raises numerous challenges with respect to environmental impact modelling, including explicit treatment of nutrients in dung and urine, the prediction of grazing behaviour, dry matter intake and associated enteric methane loss. This paper discusses these challenges and opportunities when integrating animal models into grazing system models for evaluating productivity and environmental impact.

AbstractPotato acreage and total production in Maine have declined steadily since the 1960s. In 1991, a University of Maine research team established a large-scale, long-term, comparative study of three factors that form the foundation of productive potato cropping systems: soil management, pest management, and variety choice. This study, the Potato Ecosystem Project, included 96 main plots (5.8 ha total) and near-by “component studies.” The project contrasted amended vs. unamended soil management strategies; conventional vs. reduced-input vs. bio-intensive pest management strategies; and disease and stress susceptible vs. tolerant potato varieties. Given recent concerns over resistance to pesticides and increasing costs of agricultural chemical inputs, the reduced-input and bio-intensive pest management systems provided encouraging results. Weed growth was similar in the conventional and reduced-input systems. Colorado potato beetle thresholds were exceeded less often and their densities were lower in the bio-intensive system than in the reduced-input and conventional systems. Lady beetles, which are major aphid predators, were more abundant in the bio-intensive pest management system compared with the reduced-input and conventional systems in 5 of the 6 years. Tuber yield and quality were maintained at a high level in the reduced-input system, although difficulties with plant disease, nutrient and weed management contributed to significantly lower yields in the bio-intensive pest management system. Economic analysis indicated that from 1993 to 1996, the reduced-input system had a greater return over variable cost (avg. $973 ha-1) than the conventional (avg. $890ha-1) and bio-intensive pest management systems (avg. $578ha-1). The amended soil management system achieved rapid improvements in soil quality: soil organic matter, water stable aggregates, potassium, and soluble inorganic phosphorus contents increased while requirements for synthetic fertilizers were reduced. These improvements in soil quality enhanced late-season crop vigor, canopy duration and tuber quality, and increased yields by 13% and 30% over the unamended system in 1994 and 1995, respectively, but not in 1996. Improved crop vigor in the amended soil management system also benefited weed control efforts by encouraging a more weed-suppressive potato crop. In the biointensive pest management system, in which weeds were controlled mechanically, the amended soil management system had less weed biomass than the unamended soil management system in 1994 and 1995. Conversely, the amended soil management system consistently increased flea beetle populations and, in one of two years, the incidence of Rhizoctonia. The choice of potato variety also affected pest dynamics. Total aphid density (all aphid species considered together) and almost all disease ratings were higher on ‘Superior’ than ‘Atlantic’ potato.

<p>Evaluating greenhouse gas (GHG) emissions at farm level is an important tool to mitigate climate change. Livestock account for 80% of the total GHG emissions in Uruguay, and beef cow-calf systems are possibly the largest contributors. In cow-calf grazing systems, optimizing forage allowance and grazing intensity may increase pasture productivity, reproductive performance, beef productivity, and possibly reduce GHG emissions. This study estimated GHG emissions per kg of live weight gain (LWG) and per hectare from 20 cow-calf systems in Uruguay, with different management practices. The GHG emissions were on average 20.8 kg CO<sub>2</sub>-e.kg LWG<sup>-1</sup>, ranging from 11.4 to 32.2. Beef productivity and reproductive efficiency were the main determinants of GHG emissions. Five farm clusters were identified with different productive and environmental efficiency by numerical classification of relevant variables. Improving grazing efficiency by optimizing the stocking rate and forage production can increase beef productivity by 22% and reduce GHG emissions per kg LWG by 28% compared to “low performance” management. Further improvements in reproductive efficiency can increase productivity by 41% and reduce GHG emissions per kg LWG by 23%, resulting in a “carbon smart” strategy. However, the most intensified farms with highest stocking rate and beef productivity, did not reduce GHG emissions per kg LWG, while increased GHG emissions per ha compared to the carbon smart. This analysis showed that it is possible to simultaneously reduce carbon footprint per kg and per ha, by optimizing grazing management. This study demonstrated that there is high potential to reduce cow-calf GHG emissions through improved grazing management.</p>
