The Use Of High Distillers Grains And Nutrient Management In Beef Feedlots, Amy R. Rich

Department of Animal Science: Dissertations, Theses, and Student Research

Two experiments were conducted to determine the effect of feeding wet distillers grains (WDGS) at 70% and wheat straw at 25% (DM basis) on finishing steer performance and N mass balance in open feedlot pens. Four treatments were tested as a 2x2 factorial with factors being diet and pen cleaning frequency (monthly or at the end of the feeding period). In both experiments the CON treatment (corn based diet) had greater DMI, ADG, HCW, marbling and fat depth. There was greater N intake and N excretion for both the WINTER and SUMMER experiments on the WDGS. Not all the additional …

Ethanol Byproduct Feeds: Determining Accurate Fiber Content, Nutrient Composition And Variability, Storing With Low-Quality Forages, And Fiber Utilization In Finishing Diets, Crystal D. Buckner

Department of Animal Science: Dissertations, Theses, and Student Research

The growing ethanol industry has produced vast quantities of distillers grains plus solubles (DGS) in the wet (WDGS) and dry forms and Sweet Bran wet corn gluten feed (SB). Previous research has demonstrated that these byproduct feeds result in improved feeding values compared to grass in growing diets and corn in finishing diets, with positive economic returns. Four experiments were conducted to evaluate dry matter determination methods and variability of nutrient composition for WDGS, determining the accurate method for measuring NDF in corn and DGS, compare feeding WDGS mixed with straw as either fresh or ensiled, and evaluate fiber digestibility …

Must reduce stress to animals during handling. 2. Must be cost effective to save labor and maintenance. 3. Must show improvement from the current set- up. The above parameters combine to form a system that enables the handlers of Tulloch Ranches to manage and work cattle in a more calm and humane …

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.

Sp695-Managing Cattle For A Wholesome Food Product, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

The goal of every beef producer should be to produce the highest-quality animals possible. A critical part is the way animal health practices are administered. Following recommended guidelines when giving medications and vaccines results in healthier animals, fewer carcass blemishes and a more wholesome food product. Managing cattle with the goal of producing a wholesome food product results in beef that consumers can purchase with confidence.

When working with cattle, it is important to do the job right. Producers need to learn how to correctly perform recommended management practices. This will include vaccinations, implanting, castrating, deworming and other practices.

Sp694-Implant Cattle Properly, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

When used properly, growth-stimulating implants offer the commercial cow-calf producer a fast, easy-to-use method of increasing the weaning weight of calves. Implants have been proven effective through research, as well as through routine use in the beef industry.

Implanting is a relatively easy management practice to perform; however, adequate restraint of the animal is required. If inadequate facilities are available, consideration should be given to purchasing/constructing needed components.

Sp693-Evaluate Your Beef Cattle-Handling Facilities, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

One of the keys to maximizing returns from a commercial cow-calf enterprise is the timely application of basic management practices. Many of these practices require that the cattle be worked several times a year. Without adequate cattle-handling facilities, these practices are either delayed or completely neglected.

Producers desiring to upgrade current facilities or construct or purchase new facilities may apply for a cost-share through the Tennessee Agricultural Enhancement Program administered by the Tennessee Department of Agriculture. Premise identification and Beef Quality Assurance certification are prerequisites for applying for the funds. Approval of the request must be received before items are …

Sp692-Castration Of Beef Calves, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

Castration is a management practice that should be performed on all male beef calves. Castration, the removal of the testicles of a bull by either surgical or non-surgical methods, is recommended because of consumer preference, for economic considerations and to improve the temperament of cattle.

Sp691-Biosecurity For The Beef Herd, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

Biosecurity incorporates those management practices aimed at keeping new diseases off the farm and keeping diseases from spreading from group to group on the farm. Biosecurity is the cheapest and most effective method of disease control, since vaccinations cannot eliminate disease and treatment can only reduce losses. Most cattle diseases are spread by cattle blood, saliva, manure, urine or exhaled air. Special attention must be paid to reducing contact from animal-to-animal or animal-toobject- to-animal. This is best done by a combination of animal isolation and control of movement onto and around the farm, as well as cleaning and disinfection.

Sp690-Handling Facilities For Beef Cattle, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

Beef cattle producers need good handling facilities if they are to perform recommended management practices (vaccinating, identifying, castrating, dehorning, implanting, deworming, checking for pregnancy, etc.) Producers planning to purchase a squeeze chute or other handling-facility components may apply for a cost-share through the Tennessee Agricultural Enhancement Program administered by the Tennessee Department of Agriculture. Premise identi cation and Beef Quality Assurance certi cation are prerequisites for applying for the funds. Approval of the request must be received before items are purchased.

A good handling facility allows for the treatment of animals, reduces the possibility of injury to both animal and …

A Comparitive Study On Traumatic Reticuloperitonitis And Traumatic Pericarditis In Egyptian Cattle, Mohamed M. Ghanem

Turkish Journal of Veterinary & Animal Sciences

This study was carried out on 15 Holstein cows divided into 3 groups of 5. Group 1 was the control, group 2 had traumatic reticuloperitonitis (TRP), and group 3 had traumatic pericarditis (TP). Comparison between the groups included clinical, hematological, biochemical, and ultrasonographic changes. TRP cows had arched backs, a sharp decrease in milk yield, and a reluctance to move, with abduction of the fore limbs. TP cows had edema of the brisket and submandibular region, with jugular vein distension and pulsation. TRP cows had a significant increase in PCV, leukocytes, and neutrophils, and a significant decrease in RBC, hemoglobin, …

Habitat Correlates Of Jaguar Kill-Sites Of Cattle In Northeastern Sonora, Mexico, Octavio C. Rosas-Rosas, Louis C. Bender, Raul Valdez

Human–Wildlife Interactions

Predation on cattle by the endangered jaguar (Panthera onca) can be a serious ecological and economic conflict. We investigated habitat characteristics of kill sites of cattle in Sonora, Mexico, from 1999 to 2004 to see whether habitat management or cattle distribution could be used as effective nonlethal methods to limit predation. Kill-sites were positively associated with oak, semitropical thornscrub, and xeric thornscrub vegetation types, whereas they were negatively associated with upland mesquite. Sites of cattle kills were also positively associated with proximity to permanent water sources and roads. A model including these relationships fi t kill locations well …
