Avian Botulism Information On Earlier Research Jan 1953

Avian Botulism Information On Earlier Research

United States Fish and Wildlife Service: Publications

Over the years, the disease, avian botulism, has been an important factor limiting populations of waterfowl, particularly in the West. Great numbers (doubtless millions) of ducks have died from this disease, and because of such heavy tolls, studies of the malady were begun early in the century and continued intermittently to the present time.

This summary brings up to 1950 the series of investigations on botulism by Wetmore (1918), Kalmbach (1930, 1932), Kalmbach and Gunderson (1934), Sperry (1947), and others. This information has been compiled as a service to those concerned with conservation of our waterfowl resources. A cooperative agreement …


Thin-Shelled Eggs, R H. Morris Jan 1953

Thin-Shelled Eggs, R H. Morris

Journal of the Department of Agriculture, Western Australia, Series 3

Thin-shelled eggs are responsible for a loss of thousands of pounds annually to the West Australian poultry industry. To a very large extent the flock owner can control the percentage of thin-shelled eggs laid by his flock and this article outlines how this control can be exercised.

Leaflet No 2024 - Mulesing And Tail Stripping. Proved Measures For The Control Of Crutch And Tail Strike In Sheep, J Reilly Jan 1953

Leaflet No 2024 - Mulesing And Tail Stripping. Proved Measures For The Control Of Crutch And Tail Strike In Sheep, J Reilly

Bulletins 1 - 2999

FOR many years, the losses from blowfly strike on the crutch and tail areas imposed a tremendous economic burden on the Merino sheep industry in Australia. Today, the modified Mules operation and the tail-strip treatment have provided a convincing answer to this menace. Breech wrinkles encourage strike, and although as a long-term policy, efforts are being made to eliminate wrinkles by breeding for plainness of breech, it is of the utmost importance to give the sheep IMMEDIATE protection by the most effective methods available.

Seasonal Reminders

Journal of the Department of Agriculture, Western Australia, Series 3

Poultry Notes

The March-April period affords the poultry farmer an opportunity to prepare the A ground for sowing greenfeed crops such as oats, barley, rape and lucerne. Brooder houses and rearing quarters should be cleaned out, floors disinfected with a 2% solution of caustic soda (1 lb. caustic soda to five gallons water), and all woodwork and lappings in the house sprayed with creosote. This gives the creosote a chance to soak into the woodwork long before the chickens are received.


St. John's Wort - Beetle Parasites Imported Jan 1953

St. John's Wort - Beetle Parasites Imported

Journal of the Department of Agriculture, Western Australia, Series 3

Some hundreds of thousands of Chrysomelid beetles, which attack St. John's Wort, were recently forwarded to this State by air freight from the C.S.I.R.O. Division of Entomology, Canberra, and have been liberated at Greenbushes and Forestgrove.


Studies On The Helminth Fauna Of Alaska. Xiv. Some Cestode Parasites Of The Aleutian Teal (Anus Crecca L.) With The Description Of Diorchis Longiovum N. Sp., Everett Schiller Jan 1953

Studies On The Helminth Fauna Of Alaska. Xiv. Some Cestode Parasites Of The Aleutian Teal (Anus Crecca L.) With The Description Of Diorchis Longiovum N. Sp., Everett Schiller

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The Aleutian teal (Anas Crecca nimia Friedmann) has been relatively unavailable for helminth investigations by American workers because its range in North America is restricted to the western-most Aleutian Islands.

During some parasitological studies on Amchitka, Aleutian Islands, Alaska, in May and early June 1952, in connection with sea otter mortality, the writer had the opportunity to collect 20 adult Aleutian teal. These birds, consisting of 16 males (average weight, 392 grams) and 4 females (average weight, 353 grams) were taken at the beginning of the nesting season, Autopsies revealed that 16 (80%) of these ducks were parasitized by cestodes. …


On The Land Mammals Of St. Lawrence Island, Alaska, Robert L. Rausch Jan 1953

On The Land Mammals Of St. Lawrence Island, Alaska, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The mammals occurring on St. Lawrence Island, Alaska, represent species which are widely distributed in boreal regions. They are not well known, however, and are poorly represented in collections. In the past, some of these mammals have been regarded as being specifically distinct from closely related forms occurring on the adjacent continents. It is the purpose of this paper to present some new data on these mammals, with particular reference to their taxonomy.

Bulletin No. 357 - Biennial Report, 1950-1952, R. H. Walker, D. A. Broadbent

UAES Bulletins

For sixty-four years the Utah Agricultural Experiment Station has been studying the problems of the farmer to make life on the farm more profitable and more enjoyable and in turn to improve the economy of the entire state. From the laboratories and from the experimental farms have come research results that have and will continue to mean dollars and cents to the farmer and increased prosperity to the state. Here are a few brief statements of some of the results of the work during the past two years.


The Insect Vector In Relation To Myxomatosis, J A. Button Nov 1952

The Insect Vector In Relation To Myxomatosis, J A. Button

Journal of the Department of Agriculture, Western Australia, Series 3

The rabbit is undoubtedly the greatest single pest with which agriculturalists in this country have to contend. It is, therefore, not surprising that any new and promising method of controlling the pest should be greeted with considerable interest. Although a great deal has already been written regarding the myxomatosis virus a brief and co-ordinated summary of the situation as it now exists in Australia, with particular reference to this State, should prove of value as a guide to the wider establishment of the disease next summer.


Lawns - Their Establishment And Management, H G. Elliott Nov 1952

Lawns - Their Establishment And Management, H G. Elliott

Journal of the Department of Agriculture, Western Australia, Series 3

It may be said that there is nothing more pleasing to the eye than a well kept lawn, be it in a home garden or covering a sporting area, and under Western Australian conditions there is no reason why a good lawn or turf cannot be developed and maintained-always provided that there is a sufficiency of water and proper care and attention are available.


Poison Plants Of Western Australia - Cape Tulip, C A. Gardner Nov 1952

Poison Plants Of Western Australia - Cape Tulip, C A. Gardner

Journal of the Department of Agriculture, Western Australia, Series 3

For countless ages the flora of Western Australia remained as a separate entity undisturbed by plant intruders, but following upon the arrival of the white man came a number of plants, some of which proved able colonists. These included useful plants such as the naturalised clovers; others such as the Cape weed developed here to an extent not to be observed in their natural home. Some of the plants now regarded as troublesome weeds were accidentally introduced by various agencies, while others were deliberately imported, but have since become widespread.


Seasonal Reminders Nov 1952

Seasonal Reminders

Journal of the Department of Agriculture, Western Australia, Series 3

Now that the plant is fully grown and leaves are maturing, growers should be on the way towards commencement of harvesting and curing. These operations can seriously reduce the value of a good crop if handled carelessly. If you have an even crop and are using inexperienced labour, it is possible to go around the crop the day before harvest and say how many leaves are to be picked from each plant. There may be from two to five. In an uneven crop this is impossible.

This pamphlet is a summary of the basic suggestions which were considered by the South Dakota Coordinating Committee for Missouri Basin Development.


Blood Parasites Of Some Common Texas Birds, Andrew B. Couch Jr. Oct 1952

Blood Parasites Of Some Common Texas Birds, Andrew B. Couch Jr.

Field and Laboratory

Danilwesky observed and recorded avian plasmodia in 1885. Laveran (1891) emphasized the importance of this discovery and suggested that research on bird malaria might help to solve questions on human malaria. Since then, significant papers on bird malaria have been presented by such investigators as R. W. Hegner, W. H. and Lucy G. Taliaferro, C. G. Huff, R. D. Manwell, and R. Hewitt, who studied morphology, physiology, immunity, and transmission of the parasites. Hewitt (1940) made these earlier findings readily available in his monograph on bird malaria.


Hydatid Disease In Boreal Regions, Robert L. Rausch Oct 1952

Hydatid Disease In Boreal Regions, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

It is the purpose of this paper to review the status of hydatid disease (caused by Echinococcus spp.) in the boreal regions of the world. Its importance has long been recognized in Eurasian countries, but only during recent years have investigators added anything significant to the knowledge of hydatid disease in North America. There is need to disseminate up-to-date information among medical workers in Canada and Alaska, where the disease is endemic in northern regions having a large aboriginal population. Therefore, particular emphasis will be placed on the situation in boreal North America.


Studies On The Helminth Fauna Of Alaska. Xi. Helminth Parasites Of Microtine Rodents--Taxonomic Considerations, Robert L. Rausch Oct 1952

Studies On The Helminth Fauna Of Alaska. Xi. Helminth Parasites Of Microtine Rodents--Taxonomic Considerations, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A survey of the helminth parasites of Alaskan rodents has been carried on by the writer since the winter of 1948-1949, as a continuation of an investigation begun in the central United States in 1942. Results of this work indicate that, despite the size of the Territory of Alaska, the survey is complete enough to furnish a reasonable knowledge of the species of helminths parasitic in microtine rodents in Alaska. Information derived from previous investigations serves as a standard against which the completeness of the present work may be judged. In the writer's opinion, the continuation of this work on …

On September 7, two grain silos, each with a capacity of 2,000 bushels were formally handed over to Muresk Agricultural College by representatives of the Trustees of the Wheat Pool of Western Australia.


Tree Lucerne, L C. Snook Sep 1952

Tree Lucerne, L C. Snook

Journal of the Department of Agriculture, Western Australia, Series 3

Perhaps the greatest need in our agricultural areas is for a hardy legume which year after year will provide palatable green fodder during the late summer months. In the white-flowered Tree Lucerne (Cystisus prolifer) such a legume is available. Surprisingly enough, this hardy perennial shrub has never been exploited. Tree Lucerne is so hardy that self-seeded thickets can be seen growing on virgin land in the Darling Ranges and I have seen seedlings in the streets of Corrigin healthy and robust after six months without rain. The foliage is so palatable that cattle and horses will break down quite large …


Trees Of Western Australia - Gimlets And Pear Fruited Mallee, C A. Gardner Sep 1952

Trees Of Western Australia - Gimlets And Pear Fruited Mallee, C A. Gardner

Journal of the Department of Agriculture, Western Australia, Series 3

Next to the salmon gum, the gimlet tree is perhaps the best-known of the trees of the Eastern Agricultural Districts and the Eastern Goldfields. A thin reddish brown bark, and a fluted or spirally-twisted trunk (especially in the young trees), distinguish at a- glance the gimlet trees or fluted gums from all other Eucalyptus trees. This bark has a thin outer layer which when removed reveals a sappy pale green, inner bark, and sometimes this inner green bark is exposed when the trees shed their reddish-brown outer bark towards the end of summer.

Hints On Chicken Rearing, R H. Morris Jul 1952

Hints On Chicken Rearing, R H. Morris

Journal of the Department of Agriculture, Western Australia, Series 3

The ultimate profit to be made from poultry farming depends largely on how successfully each year's chickens are reared. A bird can be made or marred during its growing life and many aspects must be considered in rearing chickens successfully, some of the more important of which I will treat very briefly today.


Poison Plants Of Western Australia: Toxic Plants Of The Genera Gastrolobium And Oxylobium, C A. Gardner, H W. Bennetts Jul 1952

Poison Plants Of Western Australia: Toxic Plants Of The Genera Gastrolobium And Oxylobium, C A. Gardner, H W. Bennetts

Journal of the Department of Agriculture, Western Australia, Series 3

Since the early days of settlement in Western Australia very heavy stock losses have resulted from the many poisonous species of the two closely related genera, Gastrolobium and Oxylobium which, with two exceptions, are widely distributed throughout the southern areas of the State. They constitute the largest groups of native poisonous plants and have been responsible for a large proportion of the economic losses due to plant poisoning.

Season Reminders, T G. Haney

Journal of the Department of Agriculture, Western Australia, Series 3

Now that the sales are over, growers should be ready to take good care of the tobacco seedlings for next season's crop. A good stand of healthy seedlings goes a long way towards an even crop, and is the first step towards better tobacco.
