Effect Of Endophyte-Infected Tall Fescue Toxins On Growth Performance And The Microbial Community In The Rumen And Feces In Pregnant Ewes, Saleh Alrashedi

Graduate Theses and Dissertations

Fifty pregnant Katahdin ewes grazed pastures with high (HE) and moderate (MI) levels of Neotyphodium coenophialum-infected tall fescue between February 1 and May 24 to determine the impacts of tall fescue toxins on body weight (BW), body condition scores, FAMACHA scores, fecal egg counts (FEC), and serum Cu, Zn, prolactin, and non-esterified fatty acids (NEFA). Within those 50 ewes, 15 were selected randomly for fecal and rumen sampling to assess the impacts of HE and MI on the microbiome community. Total bacterial DNA was extracted from rumen and fecal samples, and alpha and beta diversities were used to relate microbiome …

Miscellaneous Publication No 33/93 - Virulent Footrot A Farmer's Guide To Eradication, Department Of Agriculture, Western Australia

Animal production and livestock published reports

The first thing to understand about virulent footrot is that it can occur on any farm in the medium to high rainfall zone. Persons who regularly buy and sell sheep have a greater risk, but even closed breeding flock properties are at risk from stray sheep.

People often associate footrot with properties managed by inefficient farmers. This is a false belief. Many good farmers have found the disease in their sheep, including high profile studs.

Footrot can strike anywhere and often without warning.

The important thing to remember is that once it is found, getting to know and understand the …

'Dermo' Fleece Rot And Body Strike On Sheep, S G. Gherardi, S. S. Sutherland, N. Monzu

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

Blowfly strike is one of the major problems confronting the sheep industry in Austrsalia, with an estimated totsalcost of control eceeding $100 million each year.

Sheep are susceptible to five types of strike: body, breach, poll, pizzle and wound. Body strike, is of greater economic importance because its sporadic occurence from year to year makes it difficult to predict and cintrol. Outbreaks of body strike after rain can affect large numbers of sheep and inflict severe production losses.

In eastern Australia fleece rot is generally considered to be the main predisposing factor to blowfly strike, but in Western Australia evidence …

New Developments In Footrot Control, R B. Richards, L. J. Depiazzi, R. V. R. Gwynn

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

The eradication policy for footrot in sheep adopted by the Western Australian Department of Agriculture has produced an overall decline in the number of properties with the disease.

Our knowledge of the disease has improved substantially as a result of the research conducted at the Slabany Regional Veterinary Laboratory in recent years. Laboratory tests now sssist stock inspectors and veterinary officers to distinguish between different forms of footrot and to quarantine and eradicate accordingly.

The recent discovery of more effective foot-bathing solutions by officers of the Victorian Department of Agriculture will greatly assist further eradication procedures.

Mycotic Dermatitis (Lumpy Wool) Of Sheep, M R. Gardiner

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

MYCOTIC dermatitis is a common disease of the skin and overlying wool of sheep (and other herbivorous animals).

The photographs show the typical crusts and scabs which result from infection of skin, hair and wool follicles by the mycotic dematitis organism.

This article reviews the causes of lumpy wool infection and sets out control measures.

Bluetongue Of Sheep, M R. Gardiner

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

BLUETONGUE is a serious disease of sheep, mainly of introduced European breeds, throughout the African continent.

It is maintained there by wild and domestic ruminants in the presence of certain insect vectors (carriers).

The disease has probably existed there from immemorial times among the indigenous ruminants, emerging as a recognised disease only when the much more susceptible European breeds were brought into the continent.

Enterotoxaemia (Pulpy Kidney Disease), J Craig

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

ENTEROTOXAEMIA, or pulpy kidney disease, is found in all areas of the world where sheep are raised and has occurred in Western Australia for many years, particularly in the great southern districts.

At one time it was known as "Beverley sheep disease."

The infectious nature of enterotoxaemia was first described by Bennets in 1932.

Down And Out [Pulpy Kidney Disease], F C. Wilkinson

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

Two days previously the weaner mob had broken through a gate into a hundred acre paddock in which an excellent green oat crop was growing.

The owner had not been particularly worried because the oats needed grazing. When however, he went to check the water troughs and found 17 weaners dead, he became perturbed.

Pinkeye In Sheep : Some Timely Comments, F C. Wilkinson

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

DURING the summer months, it is almost inevitable that numbers of sheep in Western Australia will suffer from contagious ophthalmia—or pinkeye, to give the disease its more popular name.

As it can be quite a distressing disease which can cause severe setbacks, most flock owners, knowing that medicaments are available for the treatment of pinkeye, will feel that they should do something for the affected animals.

Pulpy Kidney Is Still A Sheep Killer, F C. Wilkinson

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

ALTHOUGH considerable publicity has been given to methods of control by vaccination, numbers of sheep are lost every year in outbreaks of infectious enterotoxaemia— the disease commonly known as "pulpy kidney."
