Coccidiosis Of Calves, W A. Halhead

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

Coccidiosis is one of the commonest causes of calf loss and debility on South-West dairy farms.

Treatment and control are simple once the nature of the disease is understood.

Salmonella Infection In Farm Animals, F C. Wilkinson

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

FIFTY-EIGHT cases of salmonella infection were diagnosed in farm animals in Western Australia during 1965.

Losses, due to deaths, abortion and ill-thrift on properties where these cases occurred were often substantial and caused the owner financial hardship.

Many more outbreaks of salmonellosis undoubtedly occurred but were not brought to the notice of veterinarians.

Egg Shell Quality, R J. Bishop

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

Recent overseas work and local industry developments indicate that the calcium content of feed for laying hens in Western Australia should be increased to achieve satisfactory egg shell strength.

Age, temperature and breeding are other important influences on egg shell quality.

The Care Of Young Fruit Trees, R G. Cahill

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

MUCH planning, work and expense must go into a programme of establishing a young orchard.

Orchardists must be prepared to give the care and attention young trees need if they are to become profitable paying units.

More Sheep Per Acre, Department Of Agriculture, Western Australia

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

In the late 1950's agricultural scientists in Western Australia became convinced that much of the improved pasture in the agricultural areas of the State was going to waste.

The results of the early trials resulted in many farm demonstrations of higher carrying capacities on improved pastures in southern agricultural areas.

Stocking Rates On Light Land : Wongan Hills Research Station, R J. Lightfoot, W. L. Mcgarry

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

THE two most important things that determine the rate of return on invested capital in Merino sheep breeding and grazing are the stocking rate and lambing percentage.

Rate Of Stocking, Rate Of Fertiliser In The Chapman Valley, R J. Parkin

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

THE Chapman Valley embraces a relatively small area of country, following generally the course of the Chapman River.

The Chapman Valley proper extends from just north-east of Geraldton to Nanson, Nabawa and Naraling and includes on its fringes, areas of Narra Tarra, Moonyoonooka and areas west of Nabawa towards Northampton.

The Avondale Stocking Rate Experiment, L D. White, R. J. Lightfoot, R. N. Glencross

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

THERE is now ample evidence that stocking rates well above the usual district levels can be carried in the Avon Valley.

However, many aspects of increasing stocking rates still require investigation, particularly with lambing ewes and young sheep.

Stocking Rate And Rate Of Superphosphate In A Higher Rainfall Area, P P. Mann, B. J. Gorddard, R. N. Glencross, E. N. Fitzpatrick

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

In its virgin state the area carried a forest association of red-gum and jarrah, and the soils are typical of large areas in the south-west of Western Australia.

These gravelly soils have a high requirement for phosphate during their first years under pasture, and this trial was designed to investigate the relationship between rate of phosphate, stocking rate and pasture production over a number of seasons.

Values Of Commonly-Used Protein Supplements In Broiler Rations, D F. Hessels

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

THE performances of broiler flocks in the latter part of 1964 were below standard. Low body weights and a high incidence of gizzard erosion were common on farms.

It was therefore decided to test the biological valuss of the commonly-used protein supplements and also to try to find a correlation between gizzard erosion and any of the protein supplements.

Enterotoxaemia (Pulpy Kidney Disease), J Craig

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

ENTEROTOXAEMIA, or pulpy kidney disease, is found in all areas of the world where sheep are raised and has occurred in Western Australia for many years, particularly in the great southern districts.

At one time it was known as "Beverley sheep disease."

The infectious nature of enterotoxaemia was first described by Bennets in 1932.

The June-July period is excessively wet, causing extensive waterlogging of the soils.

1966 Beef Cattle Progress Report Of Research Activities, E. F. Frolik, H. H. Kramer

Nebraska Beef Cattle Reports

Many beef cattle breeders in the United States and other countries are following the progress of the selection experiment at the Fort Robinson Beef Cattle Research Station, Crawford, Nebraska. Three lines of Hereford cattle from the same genetic foundation are under selection. Line 21 is selected for 200-day weight. Line 22 is selected for yearling weight. Line 23 is selected for an index combining yearling weight and a score for muscling and fat thickness.

Each line is operated as a closed herd so it will be possible to determine how much improvement in economic traits can be made by selecting …

Pheremones In Trailmaking, Roxanna Young

Student Scholarship

The paper explores the complex systems of chemical communication utilized by insects, with a specific focus on the role of pheromones in the trailmaking behavior of foraging ants. Unlike hormones that act internally, pheromones are secreted externally to influence the behavior or physiology of other members of the same species. These substances are categorized into two functional groups: releaser pheromones, which trigger an immediate behavioral response via the central nervous system, and primer pheromones, which induce slower physiological changes in the recipient. 

Foraging in ant colonies typically involves a transition from exploratory scouting to organized trailing. When a scout discovers …

The Gross And Microscopic Anatomy Of The Ducts Connecting The Testis And Epididymis In The Mouse, Bruce F. Lindgren

All Graduate Theses, Dissertations, and Other Capstone Projects

In man and other mammals including the mouse, spermatozoa are produced in the testis. Before they are mature, spermatozoa leave the testis and pass through a system of excurrent ducts where they acquire an enhanced capacity for fertilization (Young, 1931; Blandau and Rumery, 1961). These ducts include the tubuli recti, rete testis, ductuli efferentes, ductus epididymidis, and ductus deferens. The contribution of individual parts of this excurrent duct system to spermatozoan maturation is poorly understood.

This study was undertaken to describe the gross and microscopic anatomy of the tubuli recti, rete testis, ductuli efferentes, and their proximal and distal connections …

Comparisons Of Broiler Rations, D F. Hessels

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

PELLETS are the most profitable feed for broiler chickens—but when they contain about two-thirds cereal, does it pay a country grower to pay freight on pellets when cereals are plentiful in his district?

A Potential Champ? [Distemper In Dogs], F C. Wilkinson

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

THE mother of this pup was an eight-year-old sheep dog and in the eyes of her owner she was a champion and well worth her keep.

She was perhaps slowing down a little, so the best looking pup out of the last litter had been kept as a possible replacement.

Relationships Among Some Physical And Chemical Parameters Of Full- Versus Limited-Fed Yorkshire Pigs Slaughtered At Different Live Weights, G. M. Babatunde, W. G. Pond, L. Dale Van Vleck, G. H. Kroening, J. T. Reid, J. R. Stouffer, G. H. Wellington

Department of Animal Science: Faculty Publications

An experiment was designed using 30 Yorkshire pigs to study the influence of slaughter weight and feed restriction on carcass cut-out data and to relate these physical measurements to the chemically-determined proximate components. As slaughter weight increased from 79 to 102 kg., the percent of all lean cuts decreased significantly, while that of fat cuts and back-fat thickness increased significantly. Absolute amounts of both fat and lean cuts increased with slaughter weight. Feed restriction significantly increased most of the lean parameters studied and reduced the fat measurements. It increased percent of head and reduced the percent of offal (gastrointestinal tract …

The Effect Of Methods Of Storage On The Gross Energy, Chemical Composition And Feeding Value Of Alfalfa, Guru Prasad Mohanty

Electronic Theses and Dissertations

Production of good quality hay or silage and its proper storage without loss of the nutritive value is an important problem for dairy farmers. They are particularly interested in meeting the energy needs in feeding their herds for milk production. During the past decade there has been a substantial increase in the volume and intensity of research towards the nutritional and calorimetric aspects of cattle feeds. A number of unavoidable problems come in the way of their application causing financial disaster in today’s competitive economy of dairy farming. To increase milk production or to maintain a high level of production, …

Trichinosis, Usda

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

Trichinosis is a disease that is caused by small threadlike worms called trichinae. I It is not catching. People get trichinosis when they eat raw or underdone pork that contains trichinae. Few of the millions of hogs killed each year for food have living trichinae in their muscles, but, since there are some, you should never eat pork that is not properly cooked. Cooking pork throughout kills the worms.

The Effects Of Single-Dose X-Irradiation On Melanocytes In The Leg Musculature And Skin Of The Pet Mouse, Barry Eckert Schaeffer

Master's Theses

While most investigations have been limited to the study of pigment cells in the epidermis and hair follicles, this work embraces pigmentation of the leg muscles and dermis as well. To this end, PET mice were used which have an abundance of pigment cells in the leg muscles, but which show restriction of integumentary melanocytes to the dermis and hair. This characteristic provided the unique opportunity of comparing isolated systems of pigment cells in their response to identical stimuli of x-rays. Because pigment cells originate in the neural crest early in development and migrate throughout the embryo, all pigment cells …

Changes In Fungi With Age I. Chemical Composition Of Rhizoctonia Solani And Sclerotium Bataticola , David Gottlieb, James L. Van Etten

Department of Plant Pathology: Faculty Publications

The chemical composition of the mycelium of Rhizoctonia solani and Sclerotium bataticola was determined in cells of various ages. The percentage, per unit of dry weight, of soluble amino nitrogen, deoxyribonucleic acid (DNA), ribonucleic acid (RNA), ergosterol, and protein decreased with age in both fungi. Total lipids and fatty acids increased with age in S. bataticola but remained constant in R. solani. Total carbohydrate increased with age in R. solani and decreased in S. bataticola. Fewer changes with age were observed when the results were calculated in ratio to DNA. There was no change in the ratios of protein, …
