Copper poisoning in sheep

ANIMALS must have small amounts of copper for a number of normal bodily functions, including growth and blood formation and, in the sheep, wool quality. The liver is used as a bank or store-house for copper which is collected from the diet and in due course issued to the body tissues as required. The sheep—in contrast to other species of animals—is apt to play the miser and hoard unnecessary amounts

Lupinosis

LUPINOSIS is a disease which has caused severe mortalities in West Australian sheep flocks in recent years, and one which—because of the important role which lupins are playing in light land development—must inevitably continue to be a matter of serious concern

Copper and cobalt deficiency of livestock in Western Australia

PART 1.—DISTRIBUTION AND EFFECTS Diseases of animals due to copper and cobalt deficiencies are well known in this MJ State where much of the original work, on the cause of these conditions, was carried out. These investigations have been recorded elsewhere and described briefly in this Journal by Filmer and Underwood (1936), Bennetts (1935), (1937), (1940), (1941) (1942) and Bennetts et. al. (1939), (1942). During more recent years the distribution of these deficiencies in Western Australia has been surveyed in some detail. This survey has been made by field investigations and by chemical estimations of animal tissues and pastures from many localities throughout the State

Photosensitation

Photosensitationis a type of sunburn. It results from the presence of certain foreign pigments in the skin, making it unusually sensitive to the effects of light (photosensitive); exposure to sunlight then results in a more or less severe inflammation of the skin (photosensitisation)

Urinary calculi of sheep in Western Australia

Urinary calculi or stones, according to reports received by the Department of Agriculture during recent years, appear to be one of the most important causes of deaths in wethers and rams in the more eastern agricultural districts

Clover disease of sheep in Western Australia

From about 1940 onwards, an infertility in ewes, together with other breeding troubles and abnormalities of the sex organs of sheep, became a very serious problem in certain regions of Wester

This survey has been made by field investigations and by chemical estimations of animal tissues and pastures from many localities throughout the State. Part 2. The control of copper and cobalt deficiencies in animal The manifestations of copper and cobalt deficiency can be prevented by the administration of appropriate mineral supplements given singly, or together where a dual deficiency exists. The choice of the means of supplementation to he adopted will depend upon environment, methods of stock management, and upon economic considerations

Poison plants of Western Australia—the birdsville indigo

The Birdsville Indigo is a plant of wide distribution, being common on the plains of India as well as being widely diffused in tropical Australia. In Western Australia, besides being widely distributed in many parts of the Kimberley Division, it is particularly abundant on the plains of the Ashburton district, and extends as far south as Williambury on the Minilya River. Other areas in which it is common are the sandy spots around Derby and Broome, where it appears to be spreading. It is also common in Central Australia around Alice Springs. The plant was included by Dymock in his Vegetable Materia Medica of India as an antiscorbutic and diuretic

Poison plants of Western Australia - Cabbage poison (Velleia discophora F. Muell.)

Cabbage poison is a plant of bitter and disagreeable taste, not readily eaten by stock, but field evidence suggests that on occasions it may be responsible for moralities, particularly of sheep. It was first tested and found to be toxic in 1939, with material obtained from Koorda-Mollerin district

Poison plants of Western Australia: isotropis

The genus Isotropis is restricted to Australia. Of the total of nine species six are recorded in Western Australia, two of them being known as Lamb poisons while the remainder have no common names. Three are known to be toxic to stock, but concerning the remaining three we have no definite information. * Poison Plants of Western Australia is an ongoing series of articles. Toxic Plants of the Genus Isotropis is the subtitle and primary focus of this article
