Palatability Of Forage Plants In North-West Sheep Pastures, R H. Collett

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

A DECLINE in carrying capacity has occurred in large areas of the Pilbara district of the North-West, due to the decrease in palatable plants and the increase in unpalatable ones.

The relative palatability of the various species to sheep is therefore a matter of considerable importance to pastoralists.

Deer Studies At Camp Ripley, Minnesota, Bernard A. Fashingbauer

Journal of the Minnesota Academy of Science

The white-tailed deer has been studied by wildlife biologists throughout its range. Additional information is required for improved management of deer in Minnesota and elsewhere. With the permission and cooperation of military authorities, deer studies have been established within the seventy square mile Camp Ripley Military Reservation and State Game Refuge near Little Falls, Minnesota. The accessibility of the area, large deer population, and habitat conditions offered an excellent location for the proposed studies. In addition, the relatively complete control of hunter use of the Camp was a decided advantage in conducting big game research.

Some of the research work …

Relation Of Heart Girth To Weight In Holsteins And Jerseys, H. P. Davis, W. W. Swett, W. R. Harvey

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Body weight is the one measurement most extensively used to evaluate growth, condition, and value for beef, and as a basis for calculating feed requirements for cattle. Weight can be determined readily by scales but unfortunately scales of a capacity adequate for weighing cattle are not always available. Thus there is a real need for a basis of estimating weight from some body measurement that can be obtained easily and at a minimum of cost and time. It is the aim of this study to utilize additional data now available to increase further the accuracy and reliability of estimating weight …

Thirsty Cows Are Poor Milkers, S R. Dunstan

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

Correcting Cobalt Deficiency, Laurence C. Snook

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

COBALT is essential in the food eaten by sheep and cattle. As little as one part of cobalt in 10,000,000 parts of food appears to be adequate.

But if this mere trace is missing, ruminants will waste away and die, even when the feed appears excellent In every other way.

Establishing Saltland Pastures, C V. Malcolm

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

WITH the approach of winter, thoughts are turning to the seeding season. It will therefore be appropriate to discuss methods of establishing saltland pastures.

This discussion will be restricted to "bluebush," creeping saltbush, and old man saltbush. Seed of these plants is available from local stock firms.

Is Your Water Supply Safe?, D C. Mickle

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

THERE can be no doubt in anyone's mind that the need for a clean, safe and adequate water supply is essential for the production of high quality milk and cream.

It naturally follows, that, even though every possible care has been taken in an endeavour to produce clean, germ-free milk and cream, contamination by bad water can render these efforts void.

Automatic Waterers For Day Old Chickens, P Smetana, W. Ward

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

ONE of the most tedious and time consuming tasks on a poultry farm is the provision of water to chicks from day old up to the age of three or four weeks.

Most poultry farmers use half-gallon glass fonts with metal bases for the first few weeks, until the chicks are old enough to use the automatic watering system usually situated along one wall of the brooder house.

This cumbersome glass font system can be replaced by the cheap and easily installed automatic watering system described below. This system has already been adopted by several local poultry farmers.

Potassium Deficiency In Medium Rainfall Areas, William John Toms

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

IT is well known that potassic fertilisers must be used for the successful growth of subterranean clover (Trifolium subterraneum L.) on many soils in the higher rainfall districts of Western Australia.

Recent investigations have shown that some soils in medium rainfall districts are also too low in potassium to grow healthy subterranean clover pastures.

The Influence Of Stock Surface Properties On Grease Resistant Films, John H. Deryke

Paper Engineering Senior Theses

Introduction

One of the main problems in applying a continuous film to a fibrous surface such as paper is that coating must cover fibers that lie in every direction. This produces a relatively rough mat, with some fibers protruding. The surface of paper varies, but all papers and board have a surface configuration resembling a range of mountains. In paper, the interstices can be loaded with fillers, but with boards, fillers are not practical due to the amount necessary. Thus, in coating board with a continuous film, the surface configuration of the board is this main determining factor of the …

Calculated Frequency Spectra For Body-Centered Cubic Lattices, Clifton Bob Clark

Journal of the Graduate Research Center

The problem of the determination of the frequency spectrum for the Born-van Karman model for an element having body-centered cubic lattice structure is described. The model is the simple one in which only central force interactions between nearest and next-nearest neighbors are considered. The extensive program for the computation by an electronic computer of the frequency distributions for eighteen values of the ratio of the two force constants is described, and the tabular histograms which resulted are given. The use of linear interpolation to obtain frequency distributions for other values of the ratio is discussed. Comparisons are made with the …

Fossils And Farmers. 2. The Ice Age, D Merrilees

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

What did the giant Australian marsupials of the "Ice Age" look like?

Fossil remains found by farmers could help reconstruct them, as well as giving some idea of conditions on the Australian continent at that time, says D. Merrilees, B.Sc, acting Curator of Palaeontology at the West Australian Museum.

Healthy Pastures, F E. Ryan

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

IN sweeping away forests to make room for pastures we have taken on the responsibility of maintaining these areas in a condition suitable for the growth of pasture plants.

This is done by a choice of suitable species, fertilising, cultivating, drainage, control of grazing and by weed and insect control.

The Use Of Lime In Market Gardens, Department Of Agriculture, Western Australia

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

THE term "lime" when used in relation to agriculture means any calcium containing material that is capable of correcting soil acidity.

While generally used for this purpose, lime has many other equally important functions in the soil.

Salty Seepages Can Be Productive, C V. Malcolm

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

MUCH has been said and written concerning the use of Paspalum vaginatum for growing on seepage areas, but the general production to be expected from seepage areas has not received much attention.

The fact is that properly handled, seepage areas can be quite productive, and can be valuable for summer grazing.

Components Of Variance Associated With Milk And Fat Records Of Artificially Sired Holstein Daughters, L. Dale Van Vleck, L. H. Wadell, C. R. Henderson

Department of Animal Science: Faculty Publications

Components of variance are estimated for the three-way classification analysis of variance of DHIA reported first and second milk and fat records of artificially sired Holstein cows and of Owner-Sampler reported milk and fat records of artificially sired Holstein cows. The total variance of milk and fat records is partitioned into the following components with the approximate percent of total variance: sire, 6%; year-season, 2%; herd, 30%; sire by year-season, 0%; sire by herd, 1–2%; herd by year-season, 6–8%; sire by herd by year-season, 1–7%; and residual, 50%.

Circadian Organization And Microbiology: Variance Spectra And A Periodogram On Behavior Of Escherichia Coli Growing In Fluid Culture, Franz Halberg, Robert L. Conner

Journal of the Minnesota Academy of Science

Over three decades ago Rogers and Greenbank (1) published observations on intermittent growth in a bacterial culture. These interesting data are analyzed further in this report by computational procedures ( 2-8) designed for detecting and evaluating the significance of nearly periodic phenomena. By such methods, circadian (about 24-hour) periodicity in a culture of E. coli is unmasked as a significant component of the recorded changes. These results extend the already broad scope of circadian temporal organization in microbiology.

Minor Elements Can Be Overdone, L T. Jones

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

T H E term "minor elements" which is now commonly used and well understood by farmers and gardeners, refers to the five essential plant foods—copper, zinc, manganese, molybdenum and boron.

These five essential plant foods are needed by all plants in minute quantities and it is relatively easy to use them in excess of actual requirements or even in toxic amounts.

In practice this is not usually a problem with cereals and pastures. The important exception is when zinc alone is added to a cereal crop low in copper and the extra zinc accentuates the copper deficiency, and poorer yields …

Microorganisms And Soil Structure, T. M. Mccalla, F. A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

SUMMARY

Good stable soil structure is valuable for promoting the growth of plants and micro-organisms by permitting enhanced aeration and water penetration and by decreasing erosion under some conditions.

Micro-organisms influence water percolation through the soil. They may plug up soil pores with byproducts of growth and reduce water percolation. On the other hand, if a soil containing a large amount of microbial products is stirred and allowed to dry, then the percolation may be high.

Micro-organisms are involved in stabilizing soil structure by their products of decomposition and their cellular binding material, such as mycelia. Microorganisms differ greatly in …

Factors Of The Microclimate Affecting The Activity Of Fox Squirrels In Southwestern Michigan, Frederick K. Courville

Masters Theses

The fox squirrel, Sciurus niger rufiventer, is an important small game animal throughout much of the Midwest. Within the last thirty years several scientific investigations have been focused on this animal, the result being that its life history and ecology are fairly well known.

Concerning the range of the fox squirrel, D. L. Allen (1943:33) states that, in Michigan, the range began to increase with the advent of the pioneers. Baumgartner (1940) and J. M. Allen (1952) noted similar occurrences in their respective states, Ohio and Indiana. In Kansas, the fox squirrel, aided by agricultural land-use, has spread westward throughout …

Least-Cost Sites For Cooperative Egg Marketing Federations For Eastern South Dakota, John S. Arnold

Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)

Traditional outlets for South Dakota eggs, outside the Midwest, are being offered greater supplies of quality eggs by nearby producers than before. As a result. South Dakota has lost much of its Eastern market and may lose its Western market. A number of cooperative associations have expressed an interest in developing more efficient egg marketing systems. Improved cooperative marketing would create increased bargaining power and higher net returns for many producers. Cooperatives have played an important function in South Dakota egg marketing for many years. Cooperatives in other parts of the country have formed federations to increase cooperative egg marketing …
