Livestock Preference For Endophyte-Infected Or Endophyte-Free Oxytropis Sericea, Ipomoea Carnea, And Ipomoea Asarifolia, James Pfister, Daniel Cook, Stephen T. Lee, Dale R. Gardner, Franklin Riet-Correa

Poisonous Plant Research (PPR)

Fungal endophyte-infected forages have been shown to alter herbivore feeding preferences. The objective of this experiment was to compare the preference of cattle, sheep, and goats for plants containing (E+) and not containing (E-) fungal endophytes using freshly harvested Oxytropis sericea, Ipomoea carnea, and Ipomoea asarifolia. Goats and sheep rejected all forage choices regardless of endophyte status except for grass and alfalfa hay. Endophyte status had no influence on cattle forage preferences. Cattle rejected all Oxytropis sericea E+ and E- choices. Cattle discriminated between Ipomoea species, preferring Ipomoea carnea to Ipomoea asarifolia (P = 0.004). In all …

Cancer Eye Of Cattle, M R. Gardiner, J. L. Anderson, D. E. Robertson

Prevent Worms In Cattle, G C De Chaneet

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

PARASITIC gastro enteritis, caused by roundworms, is a common cause of economic loss in calves, yearlings and occasionally cows in south-western Australia. Losses could be prevented if stock owners realised the full effects of these parasites, and understood the causes of worm infestation.

Feeding Urea To Cattle, D J. Barker

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

RUMINANTS normally obtain the protein they require by digestion of the organisms that inhabit the forestomach (rumen), not by direct digestion of the dietary protein they chew up and swallow.

The organisms break down the dietary protein and then rebuild proteins in the form of more organisms.

Black-Leg In Cattle, F C. Wilkinson

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

BLACK-LEG is still a serious disease of cattle in the South West coastal region, causing deaths in young cattle.

The disease is characterised by hot swollen muscles, acute lameness and rapid death.

Cattle affected are usually 6 to 12 months old, in fat condition, and grazing on lush pastures.

Higher Stocking Rates For Cattle On Irrigated Pasture : A Report From Wokalup Research Station, Maurice C. Cullity

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

The possibility that higher cattle stocking rates than those commonly used could be economical was suggested by the results of a stocking rate trial at Wokalup Research Station

Eye Cancer In Cattle, E P. Meyer

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

THE CONDITION known as eye cancer occurs in all ages and breeds of cattle but is most common in certain strains of the Hereford breed that have non-pigmented or mottled eyes and eyelids.

A yearly incidence of up to 5 per cent can occur in susceptible herds.

Bovine Tuberculosis Control In Western Australia : Past, Present And Future, M R. Gardiner

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

TWENTY YEARS AGO, tuberculosis was a widespread and serious disease in the dairy cattle of Western Australia.

Besides having a marked depressing effect on the economy of the dairying industry, bovine tuberculosis was a constant hazard to humans coming in contact with it.

Remarkable Success Of Bovine T.B. Eradication Campaign, J Shilkin

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

Less than 20 years ago Perth dairy herds had the highest T.B. incidence of any Australian capital city and half of the Kalgoorlie cattle had the disease.

Why this was so and how the eradication campaign has reduced the incidence of less than 0.3 per cent, in 128,000 cattle is discussed in this article.

Internal Parasites Of Cattle, J Craig, R. Butler, M. E. Nairn

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

Worm parasites can have a most serious effect on cattle, even causing deaths.

This article describes the main parasites of cattle, treatment with modern anthelmintic drugs and the best means of preventing and controlling worm outbreaks.

Lice On Cattle, Department Of Agriculture, Western Australia

This article describes the main species and recommended control measures.

An Assessment Of Cattle Husbandry Problems In Western Australia, W J O Wilkie

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

THE science of animal husbandry deals with all those things which affect the welfare and productivity of our domestic animals.

The relative emphasis placed on welfare and productivity depends on whether the animals are kept as pets or for profit.

Well Designed Cattle Yards, W J O Wilkie

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

GOOD yards are those in which cattle can be handled quietly, safely and efficiently.

The manner of handling is as important as the design of the yards.

Too much dog or whip can make cattle difficult, in even the best of yards.

Bracken Fern Poisoning In Cattle, P B. Lewis

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

ONE of the major problems facing farmers in the South-West of Western Australia is the hazard of bracken fern poisoning.

The Dehorning Of Cattle, J Shilkin

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

THE dehorning of cattle, both dairy and beef, has many advantages.

Breeders of stud cattle frequently claim that removal of the horns spoils the appearance of show animals and stress that the practice is cruel.

Whilst both these statements may, to some extent, be true, the advantages of the practice far outweigh any disadvantages.

A Crush For Tuberculin Testing Of Cattle, A L. Ripper

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

ALWAYS a useful asset on any farm where livestock are kept, a strongly-constructed crush is essential where tuberculin testing makes it necessary to deal with dry stock, bulls and young animals that have not been previously handled.

The crush described in this article was specially designed for tuberculin testing, but will serve equally well for vaccinating, branding, de-horning or any operation where restraint is necessary.

Bracken Poisoning In Cattle, P B. Lewis

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

THE ingestion of bracken fern causes the death of numbers of young cattle in the South-West of Western Australia every year.

Early experimental work in the United Kingdom demonstrated that bracken contained an anti-Vitamin Bl factor called thiaminase which was thought to be the cause of the poisoning, but later work indicated that a bone marrow poisoning, not yet chemically identified, was responsible.

Brucellosis Can Cause Contagious Abortion In Cattle And Undulant Fever In Man, F C. Wilkinson

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

WHEN the cow, shown in the accompanying photograph, was purchased it had a small fluid-filled lump on the left knee.

The swelling did not appear to be painful but gradually increased in size until it assumed the proportions shown in the picture.

It was a typical case of "big-knee," one of the less common manifestations of Brucellosis—the disease commonly known as contagious abortion—and a blood test of the animal confirmed the diagnosis.

The Shorthorns, J A. Mallett

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

Among "The Stud Farm of the World" the red, white and roan Shorthorns have always been given pride of place in the cattle section. They were the first of the popular cattle breeds existing today to be systematically improved, and at the present time approximately three-quarters of all the cattle in the British Isles carry a preponderance of Shorthorn blood.

More Beef From The Kimberleys, Part 2, Grant A. Smith

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

Low phosphorus content and low protein content of pastures usually go hand in hand and as most dry feed is deficient in both of these important nutritional needs, it is easy to understand why our Kimberley cattle do well in the "wet" when ample green feed is available, but fall away rapidly in condition as the feed dries out. Increasing the protein content is essentially a long-term project, but I feel that the remedying of phosphorus deficiency is an economic possibility, which could be put into effect fairly rapidly.
