Distribution And Abundance Of Pest Animals In Western Australia: A Survey Of Institutional Knowledge, Andrew P. Woolnough, Garry S. Gray, Tim J. Lowe, Winifred E. Kirkpatrick, Ken Rose, Gary R. Martin Sep 2005

Distribution And Abundance Of Pest Animals In Western Australia: A Survey Of Institutional Knowledge, Andrew P. Woolnough, Garry S. Gray, Tim J. Lowe, Winifred E. Kirkpatrick, Ken Rose, Gary R. Martin

Agriculture reports

Data on the distribution and abundance of selected pest animals were obtained for the state of Western Australia. We used institutional knowledge from the Department of Agriculture (DAWA) and the Department of Conservation and Land Management (CALM) to acquire this important information.A two-part survey process was used to capture knowledge in 104 face-to-face interviews. The first part of the survey was a questionnaire designed to capture local-area information about pest animals. The second part of the survey, a mapping exercise, was designed to capture information about the distribution and abundance of specific pest animals. The key to the mapping exercise …

Evaluation And Perceived Impacts Of The North-Central Region Sare Grants, 1988-2002, Shirley K. Trout, Charles A. Francis, John E. Barbuto Jr. Jun 2005

Evaluation And Perceived Impacts Of The North-Central Region Sare Grants, 1988-2002, Shirley K. Trout, Charles A. Francis, John E. Barbuto Jr.

Department of Agricultural Leadership, Education, and Communication: Faculty Publications

Evaluation of government-funded programs is essential to identify ways in which initial funding makes an impact and programs can improve. The purpose of this study was to understand the value of the North Central Region's Sustainable Agricultural Research and Education (SARE) grants operated through the United States Department of Agriculture, from their inception through 2002. Using both quantitative and qualitative data, impacts were explored from the perspective of former grant recipients. Survey data were collected from 171 former SARE and 33 interviews conducted with grant recipients who represented three different grant "families"--researchers, producers and educators. Descriptive, comparative, and exploratory analyses …

A Comparison Of Intrauterine And Cervical Artificial Insemination Rods On Farrowing Rate And Litter Size In Artificially Mated Sows, Robert Fitzgerald May 2005

A Comparison Of Intrauterine And Cervical Artificial Insemination Rods On Farrowing Rate And Litter Size In Artificially Mated Sows, Robert Fitzgerald

Masters Theses & Specialist Projects

This experiment compared the effects of two artificial insemination (AI) rods on farrowing rate and number of piglets born per litter. Three hundred eighty-nine sows were allotted into two experimental groups based on parity, body condition, and breed of sire influence of the sows. One hundred ninety-three matings were performed using the experimental intrauterine rod, and one hundred ninety-six matings were performed using the traditional cervical rod as the control. Total number of piglets born per litter was measured after each sow farrowed, and the farrowing rates were calculated at the end of the study. Farrowing rates were 68% and …

Nlis National Livestock Identification System. Frequently Asked Questions, Department Of Agriculture, Western Australia May 2005

Nlis National Livestock Identification System. Frequently Asked Questions, Department Of Agriculture, Western Australia

Animal production and livestock published reports

Replaces Miscellaneous Publication 29/2004

Which was issued in December 2004

Traceability is fast becoming the most prominent issue between global livestock trading partners. In the future, international markets will demand assurances that individual animals can be adequately traced for the whole of that animal's life , through multiple transactions, and ultimately to its property of birth.

In Australia, the National Livestock identification System or NLIS is the national system for lifetime traceability of livestock. NLIS will enable rapid trace back through all movements made by that animal to the property of that animal's birth in the event of a disease …


Permeability Of Corn, Soybeans, And Soft Red And White Winter Wheat As Affected By Bulk Density, Michael D. Montross, Samuel G. Mcneill May 2005

Permeability Of Corn, Soybeans, And Soft Red And White Winter Wheat As Affected By Bulk Density, Michael D. Montross, Samuel G. Mcneill

Biosystems and Agricultural Engineering Faculty Publications

Darcy’s law is a function of viscosity, permeability, and velocity and can be used to predict the airflow resistance in granular materials at low air velocities. Permeability also governs the magnitude of natural convection currents during periods of non-aerated grain storage. The permeability of corn, soybeans, soft white winter wheat, and soft red winter wheat were measured as a function of bulk density and moisture content. Air was passed through a column of grain and the flow rate and pressure drop measured. Bulk density and kernel density were also measured to determine the porosity of grain in the test column. …


Crop Yield Response To Precision Deep Tillage, Larry G. Wells, Timothy S. Stombaugh, Scott A. Shearer May 2005

Crop Yield Response To Precision Deep Tillage, Larry G. Wells, Timothy S. Stombaugh, Scott A. Shearer

Biosystems and Agricultural Engineering Faculty Publications

Experimental precision deep tillage was applied at three sites in central Kentucky with relatively well-drained silt loam soils in no-till crop production. Fields were divided into 0.4 ha (1 ac) grid cells using DGPS mapping. Assessment of soil compaction by machinery traffic was made using multiple soil cone penetrometer measurements and expressed as cone index (CI). Corn, wheat, and soybean yields were depressed in grid cells with CIavg ≥ 1.5 MPa (218 psi) prior to application of tillage treatments at sites 1 and 3, whereas at site 2, where most of the highest average CI values ranged from 1.44 …
