Bobwhite Response To Cattle Grazing In South Texas, Bradley K. Johnston, J. Alfonso Ortega-S., Leonard A. Brennan, Fidel Hernández, Humberto L. Perotto-Baldivieso Sep 2022

Bobwhite Response To Cattle Grazing In South Texas, Bradley K. Johnston, J. Alfonso Ortega-S., Leonard A. Brennan, Fidel Hernández, Humberto L. Perotto-Baldivieso

National Quail Symposium Proceedings

Range management practices to improve habitat for wildlife by reducing brush and increasing herbaceous plants, coupled with reduced stocking rates, can lead to dense stands of dominant grasses, such as four-flower trichloris (Trichloris pluriflora). This monoculture of trichloris creates dense vegetation unsuitable for northern bobwhite (Colinus virginianus; hereafter, bobwhite), reduces plant species diversity, and alters ecosystem functions. The objectives of this study are to 1) evaluate the effects of a proper cattle grazing regime to improve bobwhite habitat and 2) develop a management guide documenting how cattle grazing can be used as a tool to reduce …


Reasons Youth Choose Or Do Not Choose To Be Involved In 4-H Livestock Projects In Tennessee, Leigh Erin Fuson Dec 2016

Reasons Youth Choose Or Do Not Choose To Be Involved In 4-H Livestock Projects In Tennessee, Leigh Erin Fuson

Masters Theses

The purpose of this study was to find reasons youth choose or do not choose to be involved in 4-H livestock projects. Livestock projects are an important part of 4-H youth development because they teach life skills like responsibility and hard work. However, many youth are unable to participate or do not have the interest. This study sought to discover what motivates some youth to become involved in a livestock project and why others do not.

Focus groups were used as the data collection tool. Two groups of youth livestock participants and two groups of non-livestock participants were utilized. Themes …

W094-Tennessee Phosphorus Risk Index, The University Of Tennessee Agricultural Extension Service Apr 2010

W094-Tennessee Phosphorus Risk Index, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

In a waterbody, P is required for algae growth. In most waterbodies, the limited supply of P limits algae growth. Large amounts of P promote rapid growth of large amounts of algae or algae "blooms." This excess algae damages aquatic habitats by reducing sunlight penetration, reducing dissolved oxygen levels and promoting the growth of a toxic form of microscopic marine life. In short, it can result in fish kills, reduce aesthetic value and could make the water less desirable for livestock watering. An example of actions taken to prevent P enrichment of surface water is the lowering of phosphate levels …


W093-Procedures For Manure And Litter Sampling, The University Of Tennessee Agricultural Extension Service Apr 2010

W093-Procedures For Manure And Litter Sampling, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

Nutrient composition of manure varies with a number of factors, including animal type, bedding, ration, storage and handling, environmental conditions, field application method, age of manure, timing of sampling and sampling technique. This variability makes book values (or averages) an unreliable source for determining application rates of nitrogen, phosphorus and potassium. Each livestock production operation and manure management system is unique, and an individual farm’s manure analysis can vary from average values by 50 percent or more. Testing manure may better indicate how animal management and other factors actually affect nutrient contents and will allow for more accurate calculation of …

W092-Terminating A Permit, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

A CAFO covered under a general permit must notify the TDEC when the CAFO is no longer in operation. The TDEC retains the right to deny termination of coverage until receipt of the necessary notice and information from the permittee.

CAFO operators should remember that a closure/rehabilitation plan for the waste system was submitted as part of the original permitting process. That closure plan should have met NRCS standards and addressed the maintenance of the facility until proper closure is completed within 360 days. The TDEC may not consider the CAFO closed or terminate the permit until the closure plan …

W090-Recordkeeping, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

Recordkeeping is an essential component of a CAFO permit. A producer must keep records current to satisfy the requirements of the regulations. Additionally, without current records, inspectors cannot determine and producers cannot prove the nutrient Management plan (NMP) has been implemented as approved. All records required by the regulation must be maintained for five years, and must be made available to TDEC or EPA upon request.

W089-Discharge Events, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

All wastewater discharges from a CAFO to waters of the state of Tennessee are prohibited. For existing CAFOs, new dairy CAFOs and new cattle CAFOs, an exception will be made when either chronic or catastrophic rainfall events cause an overflow from a facility properly designed, constructed, maintained and operated to contain all process wastewater from the operation (such as wash water, parlor water, watering system overflow, etc.), plus all runoff from a 25-year, 24-hour rainfall event. For new swine and poultry CAFOs, the exception will be made if the facility was properly designed, constructed, maintained and operated to contain all …

W088-Cafo Inspections, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

As a condition of the permit, the producer must allow personnel from the TDEC or the U.S. EPA to inspect the regulated CAFO. They are required to present their credentials and will only inspect a facility “at reasonable times.” This does not mean that they may only inspect the facility at the owner’s convenience. It simply means that most inspections will be conducted during normal business hours. Large CAFOs are required to undergo a yearly inspection at a minimum. Medium CAFOs may be inspected less often.

W086-Comprehensive Nutrient Management Plans, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

A Comprehensive Nutrient Management Plan (CNMP) is a group of conservation practices and management activities that will ensure both production and natural resource protection goals are achieved. A CNMP will contain actions that address water quality criteria for the feedlot, production area and land on which the manure will be applied. It addresses natural resource concerns dealing with soil erosion, manure and organic by-products, and their potential impacts on water quality.

Animals/Livestock

All Large CAFOs with dry litter operations, all Medium CAFOs and all designated CAFOs are required to develop, submit for state approval, implement and keep on site a site-specific Nutrient Management Plan (NMP). These NMPs are very different than the plans previously required by regulations. They are extensive and focus on many aspects of livestock operations, from application of manure to conservation practices.


W083-No Potential To Discharge Determination, The University Of Tennessee Agricultural Extension Service Apr 2010

W083-No Potential To Discharge Determination, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

AFO that does not land apply manure, litter or process wastewater may request that it be determined to have no potential to discharge. If approved, the CAFO would not have to be permitted. In Tennessee, the only type of operation that could potentially meet the “No Potential to Discharge” requirements would be poultry operations that have covered litter storage and remove all litter from their operation. Any CAFO that land applies litter, manure or wastewater cannot meet the requirements. Dairy and swine operations typically do not remove all waste and wastewater from their operation because of the enormous expense of …

W081-Permit Requirements For The Poultry Industry, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

On February 12, 2003, the Environment Protection Agency (EPA) published new concentrated animal feeding operation (CAFO) regulations designed to protect or restore water quality. EPA provided the option of adopting the national EPA CAFO regulations, or states could develop and implement their own regulations. Tennessee chose to develop and implement CAFO regulations that fit Tennessee’s animal production and water quality situations. In August 2004, the Tennessee Department of Environment and Conservation (TDEC) issued the final CAFO regulations for poultry operations.

TDEC has defined a CAFO as an animal-feeding operation (AFO) if animals are confined for at least 45 days in …


Sp696-Considerations When Selecting A Commercial Squeeze Chute, The University Of Tennessee Agricultural Extension Service Apr 2010

Sp696-Considerations When Selecting A Commercial Squeeze Chute, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

Producers considering the purchase of a commercial squeeze chute have a number of factors to consider before making the nal decision. A squeeze chute is a sizable investment for most producers. Since the squeeze chute plays such an important part in the management of the beef herd, it is critical that producers select the best available squeeze chute that will meet their needs. This is too great an investment for a critical mistake to be made in the selection process.
