Cheese : As I Know It, E W H Maslin Jan 1961

Cheese : As I Know It, E W H Maslin

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

IT is probable that cheese was made accidentally in the first instance, by the carrying of milk in the stomachs of animals, when the milk clotting enzymes of the stomach converted the liquid milk into a junket or a solid mass.


Fossils And Farmers. 2. The Ice Age, D Merrilees Jan 1961

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.

Fleece Weight : The Best Culling Guide, Department Of Agriculture, Western Australia

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

Flock owners' thoughts are now turning towards culling.

Culling should remove the worst sheep and keep the best to fill the bales and breed replacements.

A valuable aid to this annual task is Culling by Fleece Weight during shearing


The Feeding Of Pigs In The Wheatbelt, S R. Dunstan Jan 1961

The Feeding Of Pigs In The Wheatbelt, S R. Dunstan

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

ONE of the biggest costs in pig-meat production is feeding, and it is of vital importance for the farmer to understand what presents a balanced and economic ration, in order that he can take steps to achieve maximum efficiency.


Vitamins And Their Relationship To Animal Health, J Shilkin Jan 1961

Vitamins And Their Relationship To Animal Health, J Shilkin

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

NUTRITIONAL problems are assuming more and more importance in stock as the years progress and while much stress is sometimes placed on the role of vitamins in nutrition, one should not lose sight of the fact that they are only part of a balanced ration which should include other constituents, such as proteins, carbohydrates and fats in suitable proportions.

Can Worms Be Controlled By Correct Feeding?, Laurence C. Snook Jan 1961

Can Worms Be Controlled By Correct Feeding?, Laurence C. Snook

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

THE extensive losses which result from the ravages of internal parasites are a matter of serious concern.

Livestock owners realise this all too well and welcome advice concerning control measures which can be adopted. Unfortunately, it is not possible to give clear cut advice on the subject.

Much publicity is given to the use of drugs which will expel the worms. Various systems of strategic drenching have been developed.

It is well to remember, however, that drenching is only one of many methods which can be used to control worm infestation.

In this talk attention will be concentrated on experimental …


Some Notes On Worms In Sheep In Southern Western Australia, I W. Parnell Jan 1961

Some Notes On Worms In Sheep In Southern Western Australia, I W. Parnell

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

DURING the last fifty or more years several surveys have been made of the worm parasites which occur in southern Western Australia.

In the 'fifties, thanks to the stimulus of Mr. H. McL. Gordon, supported by Dr. H. W. Bennetts, observations were made on the sequence of the infestations in autumn-born weaners in the country stretching from Moora to Cranbrook and Bridgetown, and later near Geraldton and Esperance.


A Crush For Tuberculin Testing Of Cattle, A L. Ripper Jan 1961

A Crush For Tuberculin Testing Of Cattle, A L. Ripper

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

ALWAYS a useful asset on any farm where livestock are kept, a strongly-constructed crush is essential where tuberculin testing makes it necessary to deal with dry stock, bulls and young animals that have not been previously handled.

The crush described in this article was specially designed for tuberculin testing, but will serve equally well for vaccinating, branding, de-horning or any operation where restraint is necessary.


Hay For The Dairy Herd : Quality Or Quantity?, F E. Ryan Jan 1961

Hay For The Dairy Herd : Quality Or Quantity?, F E. Ryan

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

CONSERVATION of hay on dairy farms has increased in recent years but so far emphasis has been on quantity rather than quality and in some districts paddocks are closed up very early to increase yields per acre of hay.

Recent trials have shown that late closing of hay paddocks on dairy farms gives higher quality hay, more winter grazing and a better balanced pasture. The gain in quality more than compensates for any drop in yield.


Selecting A Herd Sire, R A. Bettenay Jan 1961

Selecting A Herd Sire, R A. Bettenay

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

THERE is now ample evidence that most of the differences in production between herds are determined by feeding and management, with differences in genetic merit playing a relatively minor role.

It seems that the quickest way to increase production is by improved feeding, whilst in some herds much production is being lost by faulty milking techniques.


National Parks Of Western Australia, Clee Francis Howard Jenkins Jan 1961

National Parks Of Western Australia, Clee Francis Howard Jenkins

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

NATIONAL PARKS," says the Encyclopaedia Britannica, "are spacious land areas, essentially of primitive or wilderness character, that contain scenery and natural wonder so outstanding in quality that their preservation intact for the benefit, enjoyment and inspiration of the people, is a national concern."


Let's Look At Herringbone Dairies, R A. Bettenay, F. Fielder Jan 1961

Let's Look At Herringbone Dairies, R A. Bettenay, F. Fielder

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

THE first of the modern type herringbone dairies in Western Australia was constructed by Mr. F. Tucker of Ruabon, in 1957.

Since then there has been strong interest in this system, and there are now at least six such sheds operating in the district between Ludlow and Augusta. Many more are being constructed.

POULTRY diseases constitute a major factor in losses sustained by the industry.

It is the aim of this article to provide a ready source of information to assist the poultry farmer in understanding the common disease conditions that he is likely to encounter and to suggest possible means of control and treatment.


Pickled Wheat Is Safe For Sheep : Feeding Trial, J Craig, H. P. Dwyer Jan 1961

Pickled Wheat Is Safe For Sheep : Feeding Trial, J Craig, H. P. Dwyer

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

FARMERS are often left with a surplus of pickled grain from seed wheat supplies. Many would like to feed this to their stock, but do not do so because they think there may be a risk of poisoning.

This trial was designed to investigate the effects of feeding such grain to sheep.


49th Annual Feeders Day Progress Report: Improving Beef Production Through Nutrition And Management, E. F. Frolik, A. W. Epp Jan 1961

49th Annual Feeders Day Progress Report: Improving Beef Production Through Nutrition And Management, E. F. Frolik, A. W. Epp

Nebraska Beef Cattle Reports

The science of nutrition has come into its own in the last few years. Greater recognition of the value of protein, the identification of new nutrients and the awareness of the importance of nutrition to health have been part of this trend.

In this new era in nutrition, beef has been found to be one of our most nutritious foods. Not only does it contain a generous amount of protein, but its protein is of high quality, too. In addition, beef supplies important minerals such as iron and phosphorus, which contribute to healthy blood and sturdy bones. The essential B …

Components Of Variance Associated With Milk And Fat Records Of Artificially Sired Holstein Daughters, L. Dale Van Vleck, L. H. Wadell, C. R. Henderson Jan 1961

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%.


Wintering Distribution Changes In Mallards And Black Ducks, Paul A. Johnsgard Jan 1961

Wintering Distribution Changes In Mallards And Black Ducks, Paul A. Johnsgard

Papers in Ornithology

Through the use of data compiled by the Audubon Society's annual Christmas Counts, an attempt has been made to trace the distributional changes of wintering Mallards and Black Ducks in the eastern states from 1900 to the present. During this period the Black Duck has increased relative to the Mallard in few if any states (the Great Lakes region), whereas the Mallard has increased nearly everywhere else (except in the extreme northeast), particularly in the southern coastal states. Deforestation and changes in land use are sug- gested as probable reasons for this trend, which is not likely to be reversed.


Chemical Poisoning In Animals. 2. Lead, H D. Seddon Jan 1961

Chemical Poisoning In Animals. 2. Lead, H D. Seddon

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

LEAD is the most frequent cause of poisoning in farm animals, especially of cattle.

All animals and man are susceptible to large doses, but small repeated doses may accumulate to toxic proportions in the body.

Cattle and sheep are more susceptible to poisoning and are more likely to have access to sources of lead.


Antibiotics And Sterilisers In The Dairy Industry, K Needham, N. Ingleton Jan 1961

Antibiotics And Sterilisers In The Dairy Industry, K Needham, N. Ingleton

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

A S a consequence of the rapid advances made in all aspects of technology there are an ever increasing number of preparations becoming available to the dairy farmer, to assist both in the control of disease in his crops, pastures and animals and to maintain and enhance the quality of his dairy products.

These are—antibiotics, sterilisers, detergents, various weedicides and pesticides

Saving Labour In Feeding Calves, R A. Bettenay Jan 1961

Saving Labour In Feeding Calves, R A. Bettenay

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

PRESENT day values are such that no farmer can afford not to dispose of his calves to the best advantage.

With the lighter breeds this might still mean vealing all bull calves within a week of birth, but with heavier breeds it is now more economical to keep all calves until they are at least six to eight months old.


Sarcoptic Mange Of Pigs, H D. Seddon, F. C. Wilkinson Jan 1961

Sarcoptic Mange Of Pigs, H D. Seddon, F. C. Wilkinson

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

THIS parasitic disease appears to be much more common than is usually recognised; for, while severe cases with chronic skin lesions are readily seen, light infestations, especially on coloured pigs often go unnoticed.

When it is realised that even lightly infested pigs require twice as much feed to make one pound gain in live weight as do uninfested pigs, then early recognition and treatment of the disease becomes an obvious economical necessity.


Swine Brucellosis: How You Can Eradicate It Jan 1961

Swine Brucellosis: How You Can Eradicate It

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

Swine brucellosis is a bacterial disease that affects swine, other domestic animals, and humans. Severe exposure causes the disease in cattle, dogs, cats, and poultry. The disease can spread from one species of animal to another, and from animals to humans. However, it does not normally spread from one human to another, or from humans to animals. The disease costs the swine industry about $10 million a year. Losses due to human infection cannot be estimated. Although human brucellosis, or undulant fever, is difficult to diagnose-especially in mild cases-a total of 892 cases were documented in the United States in …

The Physiological Effects Of Strychnine And Electric Stimuli On Cyclops, Ralph J. Fricke Jan 1961

The Physiological Effects Of Strychnine And Electric Stimuli On Cyclops, Ralph J. Fricke

Journal of the Minnesota Academy of Science

Cyclops, the intermediate hosts of parasites of higher animal~, particularly some tapeworms of fish, waterfowl, and some mammals is a comparatively simply crustacean. From the following it should become apparent that the Cyclops is, in fact, very complex, exhibiting physiological reactions similar to those produced in the mammal. This study will include certain observations of the physiological effects of strychnine and electric stimuli on Cyclops. The animal lacks a heart. Body fluid is circulated as a result of the rhythmic movements of its gut. For the experiments a clone of the species Eueyclops agilis was established. In a clone, all …


An Investigation Of Possible Commensalism In Red Squirrels, Yellow-Bellied Sapsuckers, And Humming-Birds At The Lake Itasca Biological Station, John C. Coulter Jan 1961

An Investigation Of Possible Commensalism In Red Squirrels, Yellow-Bellied Sapsuckers, And Humming-Birds At The Lake Itasca Biological Station, John C. Coulter

Journal of the Minnesota Academy of Science

This is an investigation of a relationship noted at the Lake Itasca Biological Station. It was noted that the Red Squirrel, Tamiasciurus hudsonicus, in some locations spent a considerable amount of time lapping sap from the rows of holes drilled in the White Birch, Betula papyrifera, by the Yellow-bellied Sapsuckers, Sphyropious varius varius (L.). After the invasion of the red squirrel the sapsuckers and the Ruby-throated Hummingbird, Archilochus colubris (L.) continued to utilize the same food supply as well as a considerably number of insects. The two general objectives of this endeavor were then to investigate some of the related …
