Enteric Redmouth Disease Of Salmonids, G. L. Bullock

United States Fish and Wildlife Service: Publications

Enteric redmouth disease (ERM) is a systemic bacterial infection of fishes, but is principally known for its occurrence in rainbow trout, Salmo gairdneri. The disease was first reported in the 1950's by Rucker (1966), and in recognition of that fact, the causal organism was named Yersinia ruckeri by Ewing et al. (1978). Although Wagner and Perkins (1952) described a bacterial disease that produced a red-mouth condition in rainbow trout in California and Colorado, it was caused by a different bacterium; they isolated Pseudomonas hydrophila rather than Y. ruckeri.

The Effects Of Calcium Hydroxide Treatment Of Sunflower Seeds On Ration Digestibility And Rumen Parameters In Holstein Steers, Ann C. Spearow

Electronic Theses and Dissertations

Digestibilities of rations containing 10% (dry matter basis) oil-type, rolled sunflower seeds treated with three levels- of calcium hydroxide were compared using .a randomized complete block design. Forty-eight Holstein steers were fed one of six completely mixed rations consisting of (DM basis) 44% corn silage, 10% chopped alfalfa hay, and 46% concentrate mix. Concentrate mixes contained: CSM = control; SCS =control+ 22% sunflower seeds; SCL = SCS + 3.5% additional limestone; SCH2, SCH4, and SCH8 = SCS + 2, 4, and 8% calcium hydroxide (% sunflower seed DM), respectively. Total rations were isonitrogeneous at approximately 16% crude protein and isocaloric …

Autecology Of The Black Needlerush Juncus Roemerianus, Lionel N. Eleuterius

Gulf and Caribbean Research

Juncus roemerianus generally occupies the upper half of the intertidal plane and covers about 92% or 25,000 hectares of marsh in Mississippi. The vegetative canopy is best described as a series of disjunct and intergrading populations. Considerable phenotypic variation and differences in standing crop exist between populations. J. roemerianus has very wide environmental tolerances in comparison to all other tidal marsh angiosperms. Soil types inhabited by the rush range from very sandy to highly organic muds and peats, which may vary in the concentration of nutrient elements (nitrogen, phosphorus and potassium). Neither soil type, nutrient concentration, water content, pH nor …

Sulphur Needs Of Crops And Pastures, J S. Yeates

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

Sulphur deficiency has long been recognised as a potential problem of legume pastures in the higher rainfall areas (over 750 mm a year) of south-west Western Australia. Before the introduction of granulated superphosphate (about 1970), sulfer deficiencies commonly developed in spring on susceptible soils despite autumn applications of superphosphate (containing about 10.5 per cent sulphur).

In loww and medium rainfall areas sulphur deficiency is rarely reported, at least partly because of annual superphosphate applications. However large areas of the sandy-surfaced soils of Western Australia would become sulphur deficient for pastures and crops if sulphur inputsd in fertilisers were substantially reduced. …

Seedcorn Maggot (Diptera: Anthomyiidae) Reproductive Biology And Techniques For Examining Ovarian Dynamics, L. G. Higley, L. P. Pedigo

Department of Entomology: Faculty Publications

We developed techniques for examining ovarian dynamics of the seedcorn maggot, Delia platura (Meigen), and delineated detailed procedures for ovarian dissections and classifications.A three-class ovarian rating system was devised and physiological ages for each class were determined. The preovipositional period was 36 degree-days (DD) in the field and 100 DD in the laboratory. No ovarian development was observed unlessfemales had been given a protein food source. All females with ovarian development had mated.

Barley Production And Soil Acidity, P J. Dolling, W. M. Porter

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

One of the causes of reduced plant yields on acid soils is aluminium toxicity. because barley is extremely sensitive to this mineral, a project started last year to examine the influence of soil acidity on barley production in the main barley growing areas of Western Australia.

This article discusses some of the background information on the project and its aims.

Modifying Fertiliser Practices, J S. Yeates, D. M. Deeley, M. F. Clarke, D. Allen

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

If modified fertiliser practices are adopted phosphorus losses from the Peel-Harvey catchment can be reduced. Farmers can save money on fertiliser applications and the need for more expensive catchment management measures to reduce algal pollution of the estuary will be avoided.

Research data available so far indicate that, with farmer co-operation and the use of the new slow release fertiliser New Coastal Superphosphate, long-term phosphorus application rates can be reduced by 30-40 per cent - and possibly even halved - without lowering agricultural production. This will also reduce phosphorus loss to drainage water.

Although much of the research since 1982 …

Bush Flies : Where They All Come From, J N. Matthiessen

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

The bush fly is a native Australian insect which breeds in dung and has its reproductive opportunities greatly expanded by the introduction of cattle into the country.

In the agricultural region of south-western Australia bush flies appear in large numbers in spring and early summer. The occurrence of such massive numbers then can be traced back to short periods of very successful breeding that begin in the cool early weeks of spring when flies are hardly noticeable.

Catabolite Repression Of Chloroplast Development In Euglena, Antonio F. Monroy, Steven D. Scheartzbach

School of Biological Sciences: Faculty Publications

Two-dimensional gel electrophoresis resolved total cellular protein from Euglena gracifis Klebs var. bacillaris Cori into 640 polypeptides detectable by silver staining. The addition of 84 mM ethanol to dark-grown resting carbon- starved cells increased the relative amounts of 6 polypeptides and decreased the relative amounts of 3 polypeptides. The addition of 84 mM malate to resting cells increased the relative amounts of 3 of the ethanol-induced polypeptides, suggesting that the induction of these polypeptides represents a generalized response to the provision of a utilizable carbon source, a nutritional shift up, rather than a specific response to ethanol addition. Exposure of …

Herbivore Effect On Stature, Fruiting, And Leaf Dynamics Of A Native Crucifer, Svata M. Louda

Svata M. Louda Publications

The impact of a native, leaf-feeding chrysomelid beetle (Phaedon sp. nr. oviformis) on bittercress (Cardamine cordifolia: Cruciferae), was evaluated in an exclusion experiment. Multivariate statistical analysis showed a significant increase in plant performance in the rotenone exclusion compared to performance in the paired control treatment. Plant response to the reduction of herbivory was a complicated, interrelated syndrome of changes. When insects were excluded, the amount of missing leaf area decreased significantly (3.6-fold; 3.2-0.9 cm² per plant), and the total leaf area increased 5.7-fold (12.9-73.4 cm² per plant). Plant height (5.7-20.3 cm) and fruit production …

Effects Of Water Flow Restriction And Environmental Factors On Performance Of Nursery-Age Pigs, John A. Neinaber, G. Leroy Hahn

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

A series of three feeding trials was conducted to determine if nipple waterer flow rate affects the performance of nursery-age pigs and if there are any interaction effects with environmental factors. In the first trial, 42 barrows, 10 wk of age, were fed during a period of 4 wk at 5 or 35 C and given water ad libitum with flow rates of 100, 600 and 1,100 ml/min and a control treatment of 20 C and 600 ml/min.

Manipulation Of Endogenous And Exogenous Hormones For Red Meat Production, Bruce D. Schanbacher

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Growth and development of domestic livestock for red meat production are often discussed in the context of environmental factors, nutritional requirements, genetic potential and the anabolic agents affecting production efficiency. In this minireview, the effects of endogenous and exogenous hormones on animal growth are reviewed. The pituitary, pancreatic and gonadal hormones known to affect growth and(or) carcass composition are cited to illustrate and place into perspective the important contributions that the endocrine system makes to animal production. Manipulation of endogenous hormones through 1) administration of synthetic releasing and inhibiting peptides and 2) immunoneutralization techniques, will likely provide the livestock producer …

A Report On A Pilot Study On Cattle Grazed Patches In Herbaceous Vegetation, Victor Povilaitis

Undergraduate Honors Capstone Projects

Since the late 1960's, the term station (Goddard 1968), feeding station (Novellie 1978, Underwood 1982), and feeding site (Underwood 1983) have been used to describe the area in front of a foraging animal in which it can access forage without moving its front legs. The area is a hypothecial semicircle in front of the grazing animal, but the vegetation actually impacted by defoliation may be considered a "grazed patch," which may be the sum of several feeding stations. As animals graze the vegetation in an area, grazed patches are created. Presently, it is undocumented if such patches influence the behavior …
