Autumn Lambing Means Autumn Feeding, C J. Spencer Jan 1960

Autumn Lambing Means Autumn Feeding, C J. Spencer

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

MANY Merino flocks in the agricultural areas Iamb down in the autumn months.

This means that the lambs are being developed and reared when paddock feed is at its worst, and this in turn means that a well-planned supplementary feeding programme is essential.


Famous Sheep Breeds. 4. The Border Leicester, J A. Mallett Jan 1960

Famous Sheep Breeds. 4. The Border Leicester, J A. Mallett

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

ALTHOUGH the Society of Border Leicester Sheep Breeders was formed only 62 years ago and the first volume of the Border Leicester Flock Book appeared in 1899, surprisingly little authentic information is available concerning the origin of the breed.


Studies In The Mulga Pastoral Zone. 1. The Grazing Of Wandarrie Grass Associations, D G. Wilcox Jan 1960

Studies In The Mulga Pastoral Zone. 1. The Grazing Of Wandarrie Grass Associations, D G. Wilcox

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

THE establishment of the Wiluna office of the North-West Branch marked the commencement of a series of investigations into the pastures of the mulga zone.

Unlike the agricultural areas where a fund of knowledge exists on the growth habits of the pastures, the pastures of this area were completely unknown.

The preliminary investigations had to be aimed at forming an understanding of the reactions of the various plants to rain, to temperature and seasonal conditions and to grazing in an area of extremely low rainfall reliability.


Studies In The Mulga Pastoral Zone. 2. Some Aspects Of The Value Of The Mulga Scrub, D G. Wilcox Jan 1960

Studies In The Mulga Pastoral Zone. 2. Some Aspects Of The Value Of The Mulga Scrub, D G. Wilcox

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

THE mulga pastoral zone is so named since most of its area is dominated by Mulga (Acacia aneura).

The mulga is found associated with shrubs and grasses in almost all plant habitats. In its various forms it can associate with spinifex (Triodia basedowi), Wandarrie Grasses (Danthonia, Eragostis and Eriachne spp.) and with low shrubs on flood plains, hills and breakaways. It may even attempt to become established in salty communities, though this is never completely successful.

The scene the area offers from its low hills is one of a succession of low undulations, occasionally scarred by creeks or breakaways and …

Malaysian Parasites Xxxv-Xlix, W. W. Macdonald Jan 1960

Malaysian Parasites Xxxv-Xlix, W. W. Macdonald

Harold W. Manter Laboratory of Parasitology: Faculty Publications

This is the third Study of the series from this Institute on the external and internal parasites and the biting insects of the Malaysian region. The earlier two volumes were planned and edited by Dr. J.R. Audy, and on his departure from Malaya in the middle of 1959 Mr. W. W. Macdonald continued the work which had been begun and collated and edited the papers in this present Study.

In the two previous volumes (Study No. 26, 1954 and No. 28, 1957) the emphasis was on the taxonomy of Trombiculid mites. In the present volume the emphasis has changed, and …


Studies On The Helminth Fauna Of Alaska. Xxxvil. Description Of Schizorchis Caballeroi N. Sp. (Cestoda: Anoplocephalidae), With Notes On Other Parasites Of Ochotona, Robert L. Rausch Jan 1960

Studies On The Helminth Fauna Of Alaska. Xxxvil. Description Of Schizorchis Caballeroi N. Sp. (Cestoda: Anoplocephalidae), With Notes On Other Parasites Of Ochotona, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Schizorchis caballeroi n. sp. has been described from the collared pika, Ochotona collaris (Nelson), from Alaska, and has been distinguished morphologically from its congeners, S. ochotonae Hansen, 1948, and S. altaica Gvozdev, 1951.

Nine species of helminths have been described 10 dale from North American pikas, O. collaris and O. princeps (Richardson). These mammals are markedly allopatric and do not share any species of helminth. Nematodes of two genera, Eugenuris Shults and Labiostomum Akhtar, 1941, occur in O. collaris as weIl as in palearctic species of Ochotona. This, along with other pertinent information, is taken to suggest that O. …


Observations Of The Growth Of Two Strains Of Trichomonas Augusta From Amphibians, William Carl Von Meyer Jan 1960

Observations Of The Growth Of Two Strains Of Trichomonas Augusta From Amphibians, William Carl Von Meyer

University of the Pacific Theses and Dissertations

This study was begun with three purposes in mind. One was to develop a better medium for the cultivation of flagellate protozoans of the genus Trichomonas by varying the viscosity and nutrient content of the constituents. The second was to determine, by rates of division, the effects of various antibiotics upon axenic cultures, and the third, was to compare division rates in various media which did not contain antibiotics. Since the few axenic cultures which were obtained lasted a maximum of four hours, the emphasis of the problem was shifted to the behavior of Trichomonas augusta growing in association with …

Effects Of Reserpine (Serpasil) On Bloat, Edward P. Michalewicz Jan 1960

Effects Of Reserpine (Serpasil) On Bloat, Edward P. Michalewicz

Electronic Theses and Dissertations

Farmers and ranchers have been faced with the problem of bloat for many centuries. Thus far there has been little concrete evidence form research in determining the cause, finding a cure or a preventive for bloat. Numerous preventives for bloat have been practically useless. Investigators have used oils and paraffin’s as prophylactic and therapeutic measure against legume bloat. Antibiotics have been used as preventatives with some success, antifoaming agents have little effect and are of short duration. Tranquilizers, a comparatively a new group of compounds, have produced spectacular results in combatting stress conditions in animals. The ideal effect of tranquilizers …


Observations On The Biology Of Schistocerca Venusta, David Allyn King Jan 1960

Observations On The Biology Of Schistocerca Venusta, David Allyn King

University of the Pacific Theses and Dissertations

Statement Qf the problem. The green valley grasshopper, Schistoceroa venusta Scudder, is one of the most common grasshoppers to be found in the San Joaquin Valley and environs. Despite the fact that the insect is commonplace, very little work has been done on its biology. It was the purpose of this study, therefore, to learn by field and laboratory observations of the life cycle and habits of Schistoceroa venusta.

Opecoelid Trematodes From California Including A New Species, Opecoelus Nobelei, Amal Chandra Banerjee

University of the Pacific Theses and Dissertations

The aim of this investigation was to study some of the digenetic trematodes of marine fishes from Monterey Bay, with special reference to the genus Opecoelus family Opecoelidae Ozaki 1925. Extensive work on this family has been done by Dr. D. Yaiuaguti and his colleagues in Japan. After the Allan Hancock Pacific expeditions to the Galapagos Islands in 1934. Dr. H. W. Menter described a few new species from the Galapagos and some Lexicon Islands in 1940. The same author reported a new species from La Jolla, California in 1951; but until now, no further observations have been made on …


The Effect Of Temperature On The Growth Rates Of Several California Frogs, Donald Avila Villeneuve Jan 1960

The Effect Of Temperature On The Growth Rates Of Several California Frogs, Donald Avila Villeneuve

University of the Pacific Theses and Dissertations

To date the majority of the work on the ecological significance of embryonic temperature relationships has been with Eastern Frongs. The writer is aware of only two papers describing work of this nature with California frogs: Schechtmann and Oleson (1941) working with temperature tolerance in embryos of Hyla regilla, and the work of Zweifel (1955) on the Rana boylei species group.

For this reason it seemed desireable to study the effect of temperature on the growth rates of some frogs native to California and, since work of this nature has been done with the eastern Rana catesbeiana by Moore (1942b), …
