Practices

The proposed solution is the implementation of a GPS-facilitated rotational grazing system using NoFence collars on the experimental Rockin Bar B Ranch. This will be quantitatively compared against the Traditional Free Grazing Model practiced at the Chaffin Creek Cow Company (Control) over a 24-month study period.

The core problem addressed is the threat to the sustainability of small cow/calf operations in Northeast Texas, driven by high input costs (especially winter hay), labor constraints, and the resulting producer stress. The high cost of forage inputs, comprising up to 80% of total inputs, is a prime determinant of profitability and, in drought years, can eliminate a farm's survivability.

The proposed solution seeks to overcome the major hurdles to implementing rotational grazing-namely the impractical, laborious nature of electric fencing and the financially prohibitive costs of permanent infrastructure. By using GPS collars to create virtual, flexible paddocks, the system allows for the necessary quick adjustments to optimize grazing, conserve forage, and manage stocking rates without requiring intensive, daily, physical labor.

Specific, Measurable, Achievable, and Realistic (SMART) Solution

The solution is defined by two measurable hypotheses:

1. Measurable Efficiency (Quantitative)

Hypothesis 1 (H1) proposes that GPS-facilitated rotational grazing implemented on the Rockin Bar B Ranch will demonstrate a statistically significant lower mean consumption of winter hay bales and lower mean labor hours per cow-calf unit compared to the Chaffin Creek Cow Company.

• Measurability: This will be quantified over a 24-month period using the Forage Log (number, cost of bales, tonnage) and the Labor Log (weekly hourly expenditure for grazing management).
• Achievability/Realism: The solution utilizes existing, proven GPS collar technology and implements a rotational grazing system, which is a proven practice for enhancing forage production. The data will be analyzed using a Linear Mixed Model (LMM) to ensure statistical rigor by controlling for ranch-specific and seasonal variability.

2. Measurable Resilience (Qualitative)

Hypothesis 2 (H2) proposes that GPS-facilitated rotational grazing implemented on the Rockin Bar B Ranch will report a statistically significant lower overall perceived stress score (PSS-10) than the control group.

• Measurability: Stress levels will be measured using the Perceived Stress Scale (PSS-10), and the source of stress will be qualitatively evaluated using thematic coding of narrative responses from an open-ended question and a weekly Project Journal.
• Achievability/Realism: By directly addressing the pain point of unpredictable forage scarcity and the associated financial and labor stress , the solution is realistic in its expectation to diminish stress levels and improve the rancher's quality of life.

Achieving a More Sustainable Outcome

The implementation of GPS-facilitated rotational grazing leads to a more sustainable outcome by addressing all three pillars of sustainability: Economic, Environmental, and Social (Quality of Life).

1. Economic Sustainability (Profitability and Resilience)

The project directly targets farmer profitability, which is the primary focus of the study.

• Cost Reduction: By enabling effective rotational grazing, the solution is expected to result in a reduction in supplement feed during both growing and dormant seasons. H1 aims to prove a statistically significant reduction in winter hay bales and associated fuel/labor costs.
• Drought Resilience: The system is a proactive strategy that helps manage and conserve on-site forage, providing a buffer against the unpredictable cyclic droughts that often force producers into emergency, crisis-level forage sales.
• Labor Efficiency: H1 measures the reduction in labor hours, overcoming the unsustainable labor demand of existing rotational grazing methods and freeing up time for owners who rely on off-farm income.

2. Environmental Sustainability (Land Stewardship)

Rotational grazing is a proven practice for enhancing soil health and building resilience to environmental stressors. The GPS system facilitates this stewardship:

• Soil and Water Health: The practice increases the diversity of grassland pastures, enhances water infiltration (meaning less runoff and erosion), and maximizes nutrient cycling as cows are consistently moved.
• Erosion Control: Virtual fencing allows producers to easily manage and maintain riparian areas, isolating cattle from highly erodible soils (e.g., near creek boundaries) to prevent detrimental impacts from overgrazing.

3. Social Sustainability (Quality of Life)

The project's secondary focus is farmer-centric, concentrating on the human element of farming.

• Stress Diminishment: H2 tests the expectation that when budgetary constraints are decreased, the farmer's stress levels are diminished, ultimately improving their quality of life.
• Community Vitality: Content, less-stressed farmers contribute to a more vital community, as local spending dollars are distributed, creating a multiplying effect on the local economy.

The project's findings will be summarized in a readily digestible pamphlet format (including bar graphs and quotes) to provide clear, actionable guidance for other small ranchers, overcoming the reluctance to adopt new technological approaches without proof of practice. This broad dissemination ensures the findings lead to sustainable adoption across the region.

Approaches and Methods -

This longitudinal research project will be implemented on two separate ranching operations. The Rockin Bar B Ranch (experiential group) and the Chaffin Creek Cow Company (control group) will serve as on-farm research sites, with each producer managing the daily operations her/his cow/calf operation respectively.

Study Design-

The study will include each ranch's cattle herd of ten (10) cows/calf pairs. The Rockin Bar B cow/calf pairs will be fitted with NoFence GPS collars, with only the mother cow wearing a collar. The calves will not wear collars as their movement is expected to remain in close proximity to the mother cows. The herd on the Rockin Bar B Ranch will be rotated between the paddocks throughout the growing season, with the GPS collars serving as the primary method of creating and maintaining virtual fences.

Data Collection/Analysis-

This field study will employ both quantitative and qualitative aspect, and as such will employ a mixed methods approach in analyzing the juxtaposition of data between the two ranch operations. The study focuses on the first-hand experience of two producers with a same size herd, ranch topography and grazing acreage. As such, this is a case-based study collecting data from each producer. Quantitative data collection will primarily rely on numerical record-keeping captured in forage and labor logs.

Quantitative Analysis: (Hypothesis 1)

The primary statistical tool will be the Linear Mixed Model (LMM).

• Rationale for LMM: LMMs are necessary for analyzing longitudinal data because they accurately account for correlated measurements (the same ranches measured repeatedly) and unbalanced/missing data. The LMM allows for the inclusion of Ranch ID and Month ID as Random Effects to control for inherent differences between the ranches and seasonal variability, ensuring the test of the Grazing System (the fixed effect) is robust.

• Output: Separate LMMs will be run for Hay Consumption and Labor Hours to test H1, using the Drought Index as a continuous covariate.

Qualitative data will consist of a Perceived Stress Scale (PSS-10) scored on a Liebert scale. In addition, a qualitative component comprised of open- ended question, "Thinking back over the last month, what were the main two or three issues or events that were the biggest cause of stress or pressure for you on the ranch, specifically related to the cattle or pasture management?" The narrative responses will be thematically coded to give some fidelity as to the "why". More specifically, the explanatory sequential design will be the design of choice for this research project.

The following data logs will be maintained by each producer:

• Starting from April 2026-May 2028:

Labor Log:

• A weekly labor log will document the hourly expenditure used to manage the forage on each ranch practicing either traditional free range or rotational grazing of cattle. Items such as recharging batteries (GPS system), escapes, fence repair due downed trees or similar events that ultimately effect the foraging of the different herds will be recorded.

Forage Log:

• A monthly forage log will document the number, cost of bales, labor, fuel expense to move forage around farm, tonnage of hay used for the herd.

Project Journal:

• A weekly log of the producers' personal sentiment/attitude regarding the farm/GPS system. A follow-up open ended question will be asked and thematically categorization.

Research Methods:

The research study is case based. The control group being derived from the traditional free range feeding at the Chaffin Creek Cow Company. The experimental group the Rockin Bar B Ranch utilizing the GPS collars implementing rotational grazing practice.

The project 's data collection is both quantitative (e.g. forage log, fencing labor log) and qualitative (e.g. project journal).The qualitative aspect is producer-centric, reflective of the producer's impressions and mind set regarding activities experienced in reference to feeding the respective herds. An explanatory sequential design may be utilized to juxtapose quantitative measures and qualitative content to evaluate the potential decrease in forage input and labor input as it relates to improving farmer's life/work balance.
