Effects Of Mastitis On Milk Yield And Composition, Department Of Agriculture, Western Australia

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

EVERY DAIRY farmer knows how much he spends on the treatment of cows affected with mastitis, but the actual loss in production is more difficult to estimate.

As part of the current mastitis research programme the Department of Agriculture's Animal and Dairying Divisions surveyed 37 dairy herds with a believed high incidence of mastitis.

Once Daily Calf Feeding Lowers Rearing Costs, Department Of Agriculture, Western Australia

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

The usual method of hand rearing dairy calves involves twice daily feeding of milk or milk substitutes.

This routine adds considerably to the labour necessary at milking time and may have prevented many farmers from putting much effort into dairy beef production.

The report below comes from a 1969 trial carried out at Bramley Research Station to see if once-daily calf feeding was as effective as twice daily feeding.

The trial's results should be considered as early findings from a series of trials being conducted into calf rearing regimes by both the Animal and Dairying Divisions of the Department of …

Dry Supplements Reduce Labour And Cost Of Calf Rearing, Department Of Agriculture, Western Australia

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

The conventional method of hand rearing dairy calves in Western Australia calls for the feeding of whole milk, skim milk and/or milk substitutes for periods of up to 16 weeks.

This requirement for milk and labour has often prevented beef production from becoming a major sideline on many wholemilk and butterfat farms.

The two trials reported below* were carried out at Bramley Research Station to see if milk consumption and time to weaning could be reduced by free-feeding hay and cereal based supplements.

The Protection Of Primary Production : The Role Of The Agriculture Protection Board Of Western Australia, A R. Tomlinson

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

THE main function of the Agriculture Protection Board of W.A. is, as its name implies, "protection", and, in this case, it is the State's primary production which is being protected from pest animals, birds and weeds.

In general, the Board's activities are centred on the prevention, destruction or management of animals and plants which are troublesome to agricultural or pastoral production, or are capable of being troublesome.

Calf Diarrhea (Scours): Reproduced With A Virus From A Field Outbreak, C. A. Mebus, N. R. Underdahl, M. B. Rhodes, M. J. Twiehaus

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Neonatal calf diarrhea typical of that seen in field cases was produced in colostrum-deprived calves by inoculating either feces or bacteria-free filtrates via the duodenum, orally, or by a spray (aerosol). Three calves, kept free of E. coli, developed severe diarrhea following inoculation with a bacteria-free filtrate. Intense fluorescence in the epithelium of sections of small intestine from two experimental calves was observed following staining with ftuorescein-labeled gamma globulin produced with viral antigen prepared from the feces of two experimental diarrhetic E. coli-free calves. Fluorescing cells were also present in the feces of experimental and field cases of neonatal …

Meteorological Factors Controlling The Emergence Of The Eastern Spadefoot Toad, Scaphiopus Holbrooki Holbrookii Harlan, Larry Judy

Theses, Dissertations and Capstones

Scaphiopus holbrooki holbrookii, the Eastern Spadefoot, can exist in an area for many years before it is detected. Its apparent scarcity can be explained by its secretive, fossorial habitat, protective coloration, and nocturnal behavior. Spadefoots are present at the surface locally in small numbers on any one night. They emerge only when conditions are optimum. One authority has suggested that temperature, moisture, and barometric pressure exert control over emergence.

It was the purpose of this research to discover the most important meterorological parameters and investigate how they control the behavior of Scaphiopus.

Initially the response, emergence to breed was distinguished …

The Economics Of Transition In Farming, G D. Oliver

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

UNSTABLE income is a constant farm hazard. In addition to uncertainties like over production, obsolescence, rising costs and changes in consumer tastes which menace manufacturing industries, the farmer also has to contend with yield fluctuations arising from climatic conditions over which he has no control.

The Java Sparrow, John L. Long

Tallow As A Substitute For Butterfat In The Diet Of A Young Calf, R. Sprivulis

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

WHILE cow's milk is the best food for a young calf it is also very expensive.

The normal substitute for whole milk is skim milk, but removing the butterfat from cow's milk reduces the dry matter content by 30 per cent and the digestible energy by 50 per cent.

Profitable Bacon Production In A Small Herd, B M. Goss

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

PIG HERDS are tending to become larger and more specialised, but it is still possible for the small herd of less than 20 sows to absorb by-products and spare labour very profitably.

These advantages can be lost if the scale is larger.

Bulletin No 3609 - Land Development In The South Eastern Wheatbelt, G T. Halpin, P. Nelson

Bulletins - 3000 - 3999

Interest in the development of light lands in the south-eastern wheatbelt was spurred by the many ex-servicemen seeking farms after the 1939-45 World War.

Previous attempts to develop this area had been frustrated by poor crop yields, and by the poor carrying capacity of those volunteer pastures which developed on cleared land.

Research into reasons for the poor crop results was begun in 1948-49 with trials sown by Messrs Smith and Halpin between Borden and Lake Grace. The results clearly showed the important role played by copper and zinc in successful crop growth. Since then, field trials have been conducted …

Bulletin No 3547 - Kimberley Research Station - Progress Report 1968, Western Australian Department Of Agriculture

Bulletins - 3000 - 3999

Rivers flowing to the Gulf of Carpentaria and the Timor Sea have been estimated by hydrologists to carry about three times the water transported annually over the Murray drainage system and the South Eastern slopes which, together, comprise the highly settled agricultural areas of South Eastern Australia.

In 1945, the North Australian Development Committee recommended research in the Ord-Victoria rivers region as a first step toward ultimate agricultural development of this Northern potential and, in 1946, the Kim- berley Research Station commenced operations under the joint control of the Commonwealth Scientific and Industrial Research Organization and the Western Australian Department …

Winter Beef Production Trial : Wongan Hills Research Station, D J. Barker, H. G. Cariss

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

IN 14-inch rainfall districts most rainfall occurs between May and October. It is d i f f i cult to keep beef animals fattening on summer dry pastures but such areas do have a ready supply of locally grown cereals.

Using these materials as the basis of a supplement it is possible to market prime baby-beef by June-July.

The higher prices obtained for this "winter" beef more than offset the cost of supplementary feed.
