A Credit Risk Assessment Model for Dairy Farm Borrowers in Mexico
It was concluded, based on statistical results and accuracy levels achieved by the different models estimated, that a model that considers only private land owners and that includes variables leverage and liquidity (measured by the ratios debt to asset and the net income to equity, respectively) is …

Modelling New Zealand dairy farm systems to design greenhouse gas mitigation strategies
Dairy cattle in New Zealand account for about 17% of the country’s total greenhouse gas (GHG) load. As the nation progresses in its efforts to reduce these emissions, is likely that the dairy industry will face physical constraints and/or financial costs associated with their mitigation. For this …

Computerized cost and loan payment analysis model for dairy farm feed production
Efficient economic production dictates that the dairyman minimize feed costs subject to the level of milk output if he desires to maximize profits. The purpose of the present research was to develop a working model to help dairymen estimate crop production costs so that livestock ration costs may …

Dairy farm women in the Waikato 1946-1996: fifty years of social and structural change
Research on dairy farm women in New Zealand is minimal. Women have long worked on dairy farms but their contribution remains largely invisible in the literature and documentation. Researchers have failed to duly record the changes and their implications affecting dairy farm women. This thesis …

Estimating Costs of Reducing Environmental Emissions From a Dairy Farm: Multi-objective epsilon-constraint Optimization Versus Single Objective Constrained Optimization
… optimization analysis for a representative dairy farm with two different approaches: nonlinear programming (NLP) and ϵ-constraint optimization to evaluate trade-offs among reduction of multiple pollutants including nitrogen (N), phosphorus (P), greenhouse gas (GHG), and ammonia. We evaluated …

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
… reducing environmental impacts are sought for dairy farming systems. Two strategies 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 …

Evaluating the Fate of Manure Nitrogen in Confined Dairy Waste Operations: a Full-Scale Waste Analysis and Start-Up Protocol for an Anammox-Based Treatment Technology Applicable to Dairy Waste Management
… for the removal of ammonium nitrogen from dairy waste, a novel biological wastewater treatment process, utilizing anaerobic ammonium oxidation (anammox), referred to as Oxygen-Limited Autotrophic Nitrification and Denitrification (OLAND) was examined. Due to the potential use of OLAND-based …

Small-scale biogas upgrading : feasibility study of small-scale biogas upgrading in Iceland and possible methods
… if they use the gas for the company vehicles. Dairy-Farm-scale upgrading was found only financially possible for larger farms, with at least 130-140 dairy cows producing more than 20Nm3/hr of raw gas. Without any financial support the initial cost becomes too high for farms with fewer dairy …

Labor study on Virginia dairy farms employing full time workers
Data on 376 farms were acquired from a direct mail questionnaire containing 31 questions. These farms were on a production testing program and employed one or more full time workers who spent 50% or more of their time with the herd. Characteristics on workers, farms, and working conditions were …

Airborne Dissemination of Antibiotic Resistance Genes Near Farms and Effectiveness of Ionization Against Airborne Bacteria in a Classroom
… review, we designed an experimental study at a dairy farm and swine farm, where beta-lactam was the dominant antibiotic used. We quantified ARG concentrations, size distributions, and emission rates in the air and related these to ARGs found in nearby water and soil samples over four seasons. …

The effect of available resources on the forage-grain feeding ratios and forage production systems on selected Virginia grade A dairy farms
Dairy farmers in Virginia are confronted with the problem of continually re-organizing and adjusting their farming operations in an effort to maintain or improve their competitive position. Increasing competition in dairying within the state, as well as potential competition developing in areas …

Development and Optimization of a Food-Grade Antimicrobial by Lactic Acid Bacteria Isolated from Raw Milk
… activity were found in raw milk samples from the dairy farm. Forty-seven different colonies of lactococci were screened for bacteriocin production under conditions excluding the inhibitory effect of organic acids. Five strains appeared to secrete antibacterial compounds which were active against …
