AGRICULTURE and fishing were WA's first industries. Farm production in particular, was the State's economic mainstay for many years. It re1mains crucial lo our prosperity, and its future holds enormous potential.

As well as employment and income, agriculture and fisheries provide important recreation and landscape opportunities for our highly urbanised population, rural communities and international visitors. Recreational fishing- which is extremely popular - and the emerging farm tourism industry arc direct beneficiaries of strategics developed for sustainable primary industries.

Mule Deer Highway Mortality In Northeastern Utah: An Analysis Of Population-Level Impacts And A New Mitigative System, Mark E. Lehnert

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Rerouting highways to accommodate construction of the Jordanelle Reservoir in northeastern Utah caused a dramatic increase in vehicle collisions with mule deer (Odocoileus hemionus). I evaluated the effectiveness of a new system of highway crosswalk structures installed to reduce deer losses and preserve seasonal migrations. In addition, I constructed computer simulation models to investigate how highway mortality has impacted the Jordanelle deer population.

The crosswalk system restricted deer crossings to specific, well-marked areas along highways where motorists could anticipate them. Subsequent to installation, mortality declined 42.3% and 36.8% along a four-lane and two-lane highway, respectively. I was unable …

Livestock As Seed Disseminators For Reseeding Degraded Rangelands: The Role Of Dung In Gap Formation And Plant Establishment, Brian S. Auman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Livestock (cattle and sheep) were examined as seed disseminators for reseeding degraded Intermountain rangelands. "Hycrest" crested wheatgrass [Agropyron desertorum (Fisch. ex Link) Schult. X A. cristatum (L.) Gaert.] seed was fed to yearling Holstein steers and Suffolk ewes. Dung was collected from each animal type and deposited on plots of high and low densities of an annual [cheatgrass (Bromus tectorum L.)] and perennial [squirreltail (Sitanion hystrix Nutt.)] grass species. The experiment evaluated the ability of the dung to suppress the resident vegetation, and the recruitment and establishment of Hycrest seedlings emerging from the dung.

Sheep dung had …

Pilbara Steer Growth Evaluation : 1994 - 1996, Wayne Fletcher, Brian Mcintyre, Shane Cridland Dr, J L. James

Agriculture reports

Growth potential of steers in the Pilbara - a summary. The trial was conducted over a range of conditions on three locations. The pasture type at Wyloo, the Ashburton River frontage, which is regarded as one of the most productive pasture types in the area, combined with conservative stocking, a fresh paddock and excellent seasonal conditions during 1995, gives us an indication of the District's potential. In extrapolating any of these data to other cases, consideration must be given to adjustment base

Virulent Footrot : Mild Or Severe?, Laurie Depiazzi

Journal of the Department of Agriculture, Western Australia, Series 4

The footrot eradication scheme in Western Australia has resulted in a low prevalence of severe footrot.

To appreciate the achievement, we need to understand what exactly is being eradicated. 'S' strains of Dichelorbacter nodosus, the infectious bacterium of footrot, are the target of footrot eradication. Laurie Depiazzi examines the basis for eradicating 'S' strains.

2. into longer than predicted tops

3. with the same consistency as other Australian consignments

Behavioral Characteristics Affect Habitat Selection Of Domestic Ruminants, Cody B. Scott

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

I evaluated some of the factors affecting livestock distribution by conducting experimental (Chapters II and III) and observational (Chapter IV) studies. In Chapter II, I described the effect of locations of familiar foods and social interactions on choice of feeding location by lambs. Lambs were exposed to a pasture as subgroups of strangers and companions with different dietary habits (i.e., three lambs that preferred milo with three lambs that preferred wheat). Milo was placed on one end and wheat on the other, about 100 m apart. Strangers typically fed in different locations, reflecting dietary preferences. Conversely, companions fed in both …

Regional Relativities Of Sustainable Pastoral Sheep Production In Western Australia, A. Mcr Holm, R. O'Connor, I. Foster, M. Stevens, G. Beeston

Animal production and livestock published reports

The Pastoral Wool Industry has for many years been in a parlous position. Jennings (1979) in a review of the industry nearly 15 years ago concluded that a significant number of pastoralists were in serious financial trouble, mainly resulting from the inability of station businesses to cope with the worsening terms of trade affecting rural industries. The recent collapse of the wool price has again focused attention on the future viability of the pastoral wool industry. Wilcox and Cunningham (1993) in a review of the industry in October 1993, concluded that the clean price indicator needs to increase by 50 …

A Guide To Floodplain Cattle Fencing, Department Of Agriculture, Western Australia, Main Roads, Western Australia

Animal production and livestock published reports

A seminar and workshop was held at Fitzroy Crossing in October 1993 to address the consequences of flooding to landholders and communities.

Damage to flood plain fencing was identified as one of the major concerns to landholders.

An outcome from the workshop was the decision to draw on local knowledge and collate information on options for fence and floodgate designs.

This information was to be made available to land holders and other interested parties - hence this publication.

The goal of the PD/A CRSP is to increase tilapia yields by optimizing resource use in systems based predominantly on natural pond productivity.

Should Australia Export Its Native Birds?, Ross Kingwell

Biosecurity Research Articles

Commercial export from Australia of native birds, wild or captive bred, is prohibited. This paper firstly describes the current legislation and regulations that restrict the export of native birds and discusses why governments have adopted such a regulatory approach to bird species preservation. Secondly, the paper reviews the debate concerning the export ban, pointing out strengths and weaknesses in arguments and indicating the important role of CITES. Lastly, the paper outlines a new case for a conditional lifting of the ban, whereby DNA fingerprinting is used to establish transferable property rights to overcome a main source of market failure in …

Factors Influencing The Spatial Distribution And Natural History Of Desmognathus Ochrophaeus In West Virginia, Linda D. Ordiway

Theses, Dissertations and Capstones

Desmognathus ochrophaeus, the mountain dusky salamander, is a medium-sized Desmognathine, which inhabits moist woodlands. It is a slender species with a well rounded, slim and tapering tail (Bishop 1967), and 14 costal grooves (Green and Pauley 1987). The average total length is between 70 mm and 100 mm with the tail accounting for approximately half this length (Conant and Collins, 1991). The visual appearance of this salamander is highly variable (figure 1). Most individuals have a distinct light middorsal band with straight edges and darker sides. The colors of the band may vary from yellow, orange, or red to dark …

Miscellaneous Publication No 33/93 - Virulent Footrot A Farmer's Guide To Eradication, Department Of Agriculture, Western Australia

Animal production and livestock published reports

The first thing to understand about virulent footrot is that it can occur on any farm in the medium to high rainfall zone. Persons who regularly buy and sell sheep have a greater risk, but even closed breeding flock properties are at risk from stray sheep.

People often associate footrot with properties managed by inefficient farmers. This is a false belief. Many good farmers have found the disease in their sheep, including high profile studs.

Footrot can strike anywhere and often without warning.

The important thing to remember is that once it is found, getting to know and understand the …

Bulletin 4270 - Meat Quality In Beef Cattle, Brian Mcintyre

Bulletins 4000 -

Meat quality is the sole concern of the consumer once the product reaches the supermarket shelf. Breeding, feeding or any other factors that may have been important to the beef producer have no influence over the buyer's choice. Meat quality can be divided into two components — appearance and eating quality.

Miscellaneous Publication 42/93 - Development And Dissemination Of Design Methods For Rangeland Paddocks Which Maximise Animal Production And Minimise Land Degradation, Shane Cridland, Mark Stafford Smith

Animal production and livestock published reports

Surveys of rangeland resources in Western Australia to date have shown that 23% of the area surveyed is in poor range condition. Poor condition is characterised by the loss of perennial vegetation allowing wind and water erosion. Approximately another 37% is in only fair range condition (Curry and Hacker 1990).

The loss of range condition is partly due to uneven use of paddocks by sheep and cattle. The areas close to water and the preferred pasture types are often over-utilised, while areas well away from water and less preferred pasture types are under-utilised. The result is that rangeland in good, …

Resource Inventory And Condition Survey Of The Ord River Regeneration Reserve, John De Salis

Natural resources published reports

It is now some 33 years since the Ord River Regeneration Project, the largest and most ambitious of its kind in Australian rangelands, commenced.

During this time there have been a number of publications and miscellaneous reports about the project, but this publication is by far the most comprehensive produced to date. Although the field work was undertaken in 1981, the findings recorded here will stand in a good stead as a detailed account and reference work for years to come.

Much has changed within the Regeneration Reserve area since the project commenced. Cattle and feral donkey numbers have finally …

Breeding Ewe Lambs To Lamb First As Yearlings, Nyle J. Matthews

Archived Agriculture Publications

Getting the highest possible production from ewes is a goal of every sheep producer. Sheep respond well to management and will usually pay a producer for the extra times he spends in caring for them. Breeding ewe lambs is a practice that can pay dividends but requires the right management to make it work. Many years ago this practice was deemed unwise because it severely affected the young mothers in many ways. Modern research has spelled out requirements in terms of size and management that make a successful, workable program.

Progress Toward Eradication Of Virulent Footrot, Bob Mitchell

Journal of the Department of Agriculture, Western Australia, Series 4

Western Australia is well placed to eradicate virulent footrot from the State's sheep and goat populations.

Between 1950 and 1993 the proportion of sheep flocks with footrot fell from about 15 per cent to less than 2 percent, and the 1990-92 outbreak has been turned around. One hundred and eighty properties (]. 7 per cent) of flocks, mostly in the high rainfall South-West, are in quarantine for footrot today.

This high level of footrot control is the result of strong support from the sheep industry and years of good cooperation between farmers and the Department of Agriculture.

Western Australia leads …

Should We Export Our Native Birds?, Ross Kingwell

Journal of the Department of Agriculture, Western Australia, Series 4

The export of Australia's native birds is prohibited by the Wildlife Protection (Regulation of Exports and Imports) Act 1982. A review of the Act in 1991 has not led to any relaxation of the export ban.

However, the review recommended that government examine "the practical aspects of establishing a fully funded administrative control mechanism to allow strictly regulated commercial exports of a limited number of species of captivebred native birds which are not endangered or threatened". In making this recommendation, the report acknowledged there may be a case for highly regulated export of some native bird species.

This article explores …

Selection And Development Of Replacement Beef Heifers, Norris J. Stenquist, James A. Bennett

Archived Agriculture Publications

Selection, development, management, and nutrition of heifer calves to be used as herd replacements are key factors in maintaining beef herd productivity. A cow/calf producer, to be successful, must have some goals or criterion for heifer selection and development. For practically all Utah cattle production areas, economics dictate that heifers must calve as two-year-olds. Heifers must be properly developed and managed to permit this. The following factors are important: Heifers should 1) become pregnant in the first 25 days of the breeding season, 2) give birth to a live calf with little or no calving difficulty, 3) raise a calf …

Worm Control In Sheep In Western Australia. Crack Down On Worms: An Information Guide For Advisers, Consultants, Livestock Personnel And Farmers, Department Of Agriculture, Western Australia

Animal production and livestock published reports

In Western Australia’s winter rainfall areas, the control of gastro-intestinal sheep worms is based on the strategic timing of drenches.

Sheep are drenched at a time that reduces the contamination of pastures with worm eggs and larvae in late summer and autumn. The timing of the drenches is particularly important for the control ofbrown stomach worms (Ostertagia species) and black scour worms (Trichostrongylus species)

Drenches given in late spring, when pasture is starting to dry off, and again in summer, successfully reduce pasture contamination in mid summer and autumn. A faecal egg count will determine the need and timing of …

Repeatabilities Of Pelvic Area Measurements Between And Within Technicians With Varying Levels Of Experience, Steven Ftizner

Masters Theses & Specialist Projects

There has been some concern recently about the ability of technicians to accurately measure and rank prospective replacement heifers and herd bulls for pelvic area. Two studies were conducted to determine the repeatabilities between and within technicians with varying levels of experience in measuring pelvic areas.

In both studies, virgin yearling heifers were measured for pelvic height and width to determine pelvic area. In each study, technicians included a veterinarian with several years experience in reproductive physiology practice and Western Kentucky University students with varying levels of experience in rectal examinations. In the first study , the veterinarian used both …

Swine Breed Differences In Agglutination Titers Following Vaccination With Sheep Red Blood Cells And Pasteurella Multocida (Serotype A), Kenneth Stalder

Masters Theses & Specialist Projects

An investigation into the genetic differences in the humoral immune response of swine following vaccination with a sheep red blood cell solution (SRBC) and a commercially prepared Pasteurella multocida (serotype A) bacterin (PmA) was conducted on a total of 268 pigs from two individual trials. This study was also conducted to evaluate the humoral immune response of pigs to a non-pathogen (SPEC) and a known pathogen to swine (PmA). The pigs used in the first trial were from 22 litters born between January 1991 and July 1991. The pigs consisted of Hampshire x Yorkshire (n=114), purebred Yorkshire (n=70) and Hampshire …

Post-Shearing Losses Of Sheep Following Cyclonic Rains, M. Holm Glass, R. Jacob

Animal production and livestock published reports

Sudden unpredicted rainfall during summer has caused high mortality rates in newly shorn sheep on at least two previous occasions. These occurred at Darkan, Western Australia, in 1982 (Buckman 1982) and at Kybylolite in the south-east of South Australia in 1960 (Geytenbeek 1982).

Geytenbeek (1982) reported an average mortality of 8.3%, which was highest for sheep within five days of shearing. The mortality declined for animals shorn more than seven days before the rain.

Buckman (1982) reported an average mortality of 27.9% which was highest within 12 days of shearing. The losses related directly to the amount of rain received. …
