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

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.

Plants And Asthma, Robert Dunlop Royce

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

ASTHMA is defined in the dictionary as being a disease characterised by recurring attacks of difficulty in breathing, and the causes are stated to include the inhalation of dust, or the odour of plants, flowers or animals.

Hay fever is a similar condition and this too, is caused by plants, usually at the time of flowering, when large quantities of pollen are produced.

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

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 …

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.

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.

The Natural History Of Necturus, Iv. Reproduction, Joseph P. Harris Jr.

Journal of the Graduate Research Center

Information on the life cycle of Necturus has accumulated slowly. Naturalists long were uncertain as to whether they had adult animals, since Mitchill's (1822) mistaken idea that they get to be two feet long was widely current. Lacepede (1807) believed that mudpuppies might be larval, and their adults unknown; Say (1818) that the mud puppy was the larva of the hellbender. Barton (1807) confused the mudpuppy and the hellbender. Gray (1857) was "... inclined for the present to consider the Proteus of the Lakes as a distinct kind of Batrachian, which is arrested in its development, and never reaches the …

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 …

Staining Of Barley Kernels By Bacteria, Richard W. Lutey

Journal of the Minnesota Academy of Science

The demand for beer light in color has placed emphasis on the need to regulate malting as to produce, naturally and consistently, malts that are light in color (Bawden and Artis 1954), and malt having a clean pleasing aroma (Hopkins and Krause 1937). Even when bright barley, relatively free of field fungi, is malted, the finished product tends to be darker in color than the starting materials; in some cases to the extent that bleaching with sulfur dioxide gas is required (Hopkins and Krause 1937; Oesting et al. 1949). The cause of this discoloration is not known, but bacteria might …

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.

A Grazing Management Trial For The Control Of Lupinosis In Sheep, H G. Neil, C. M. Ralph, A. W. Hogstrom

Tree Lucerne : A Fodder Crop With A Future, Laurence C. Snook

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

IN December, 1952, an article was published in this Journal drawing attention to the potential value of white flowered tree lucerne (Cytisus prolifer) as a source of nutritious green fodder during the dry summer months.

Figures were quoted to show that heavy yields could be obtained year after year with very little effort, and no outlay other than for fertiliser.

The advantages to be gained from the cultivation of this tree were made very apparent and many farmers set out to grow the shrub.

Vermin Symposium Report : Wanted : A New Approach To Rabbit Control, A R. Tomlinson

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

THE main reason why rabbits have not increased as rapidly as their amazing capabilities might have led people to expect has been a series of years not suitable for full breeding.

This has been more important than myxomatosis and "1080". This was one of the thoughts taken away by those who attended the rabbit control symposium held in Perth recently.

Vibrionic Dysentery Of Pigs, M R. Gardiner

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

VIBRIONIC DYSENTERY of pigs, also known as porcine vibriosis and swine dysentery, has been recognised for many years in the U.S.A. It was first reported in Australia in 1938, in South Australia, and later in both Victoria and New South Wales.

This brief description of a disease recently diagnosed for the first time in Western Australia is given so that breeders have some chance of recognising it in their herds. Suspected cases should be reported without delay.

Antibiotic Residues In Milk : The Farmer's Responsibility, N Ingleton

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

THE LEVEL of antibiotic residues in commercial milk supplies has been steadily increasing over the past few years.

Toxic Annuals In Horticulture, Robert Dunlop Royce

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

THE number of poisonous shrubs and trees that are grown in gardens is very great, and several of these species have been discussed in detail.

It is probable that few people realise just how many of the commonest garden plants are in some way or under some circumstances, likely to contain a toxic principle.

Furthermore, this is not confined to the longer lived plants, but it applies equally to the annual plants, both summer growing and winter growing.

Notes On The Collared Pika, Ochotona Collaris (Nelson), In Alaska, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Maps showing the geographic range of the collared pika, Ochotona collaris (Nelson), have been published recently by Hall (1951) and by Hall and Kelson (1959). According to these, this mammal occurs in the mountains between the Tanana and Yukon Rivers, and in the Alaska Range as far west as Mt. McKinley. A specimen from the summit of the Chugach Mountains (Baker, 1951) was not included on the aforementioned maps. Osgood (1904) referred to two specimens collected by C. L. McKay in the Chogmit Mountains, east of Lake Clark at the base of the Alaska Peninsula, and also mentioned a sight …
