Greener Pastures 1 - The Greener Pasture Project: Managing Nutrients In Dairy Pastures, John Lucey, Mike Bolland, Don Bennett, Richard Morris, Bill Russell, Martin Staines

Bulletins 4000 -

As dairy farmers have strived to maintain profitability, many have farmed more intensively. More cows are milked and increasing inputs of fertiliser and purchased feed are used per hectare. However, these increased nutrient inputs have far exceeded the increase in nutrient output in milk production. The increasing nutrient surplus (inputs minus outputs) from intensification on dairy farms has met with increasing community concern about the environmental footprint of the dairy industry. In some other countries, dairy farmers who have intensified by increasing nitrogen inputs are now faced with legislation controlling the amount of fertiliser nitrogen that they can use.

Lime For High Rainfall Pastures: Above 800mm Average Annual Rainfall, Mike Bolland, Bill Russell

Bulletins 4000 -

Conventional agriculture acidifies soil. As your soil becomes more acid, productive pasture species disappear and are replaced by species of low agricultural value. It is a waste of money to apply expensive fertiliser to pastures which are inherently poorly productive because they are growing in an acid soil.

The paper examines the types of lime available, how to select lime for quality and when and how much lime to apply. Maganese toxity and aluminum toxicity are examine, how to test your soil, and affect of soil acidity on bacteria and other microorgansims.

Effects Of Pre-Milking Teat Sanitation On The Quality Of Raw Milk, Laurie Depiazzi, Ian Bell

Bulletins 4000 -

The effect of Quartermate pre-milking teat sanitation on milk quality was investigated in twelve dairy herds over a period of eight weeks. Pre-milking teat sanitation was carried out on all cows for six weeks on each of six farms and mesophile and thermophile bacteria counts of raw milks were compared before the milk line (“cluster” samples), and at various points within milking plants. Rates of mastitis, vat milk iodide levels and specific bacteria were also monitored.

Bulletin No 4225 - Dairying In Western Australia, Dean Maughan

Bulletins 4000 -

Dairying in Western Australia is a small though very efficient industry. In 1989/90, 480 dairy farmers produced 266 million litres of milk for an estimated return of $84 million. The retail value of milk and dairy products was estimated to be $250 million making dairying a very significant industry in the south-west of Western Australia.

Communication Networks And The Adoption Of Three Farn Practices, P. W. Fry, F. K. Goss

All other publications

The report commences with a discussion of the diffusion and adoption model, and illustrates some of the research observations and practical outcomes that have emerged in recent years, An overview of social network research is presented as a means of understanding communication exchanges and providing data relevant to the diffusion debate. The communication and adoption studies are then reported in three separate sections in the order they were conducted. (A map of the location of the survey areas is shown in Figure I ) . The objectives, survey method, results and a summary are presented for each study.

Varieties Of Cheese, T A. Morris

Bulletins 4000 -

While Cheddar cheese is by far the main type as far as English speaking countries are concerned, it is only one of a large number of varieties of cheese which are becoming more universal in production and consumption. In other than English speaking countries Cheddar cheese is almost unknown and yet the consumption of cheese in some of these countries is very much greater. The naming of cheese types has usually been a result of the use of the name of the place where the cheese was first made. Thus cheeses of similar type but produced in a different locality …

Bulletin No 3966 - Vitamin A And Animal Health, J. Johnson

Bulletins - 3000 - 3999

Vitamin A is one of the essential vitamins for animal health. Grazing animals obtain their vitamin A requirements mostly from the carotene in green feed. This carotene is converted to Vitamin A in the intestinal wall and is passed to the liver and to a less extent the kidneys for storage. Some carotene also passes direct to the liver where it is stored before it is converted to vitamin A.

When dry pastures, hay and grains (except maize) are low in carotene content this ability of the animals to store vitamin A means that they usually have enough when there …

Bulletin No 3883 - Dairying In W.A., Western Australian Department Of Agriculture

Bulletins - 3000 - 3999

Western Australia has a small dairy industry compared with its other rural production. However, the industry has consolidated over recent years.

Tree clearing and pasture development on existing holdings and the amalgamation of small dairy farms has led to a rapid increase in the area of pasture per farm. The trend in Western Australia is towards bigger herds, more efficient dairies, more fodder conservation and increasing production per cow and per· hectare.

The trend in Western Australia is towards bigger herds, more efficient dairies, more fodder conservation and increasing production per cow and per hectare. Commercial dairy farming in Western Australia is confined to the south-western corner of the State, south of Perth, extending in a 50-kilometre-wide strip along the coast to 50 kilometres …

Bulletin No 3410 - Design Of Dairy Premises, A. L. Hamilton, F. J. Fielder

Bulletins - 3000 - 3999

CONDITIONS in the dairy industry are changing rapidly.

There is a trend towards larger and more convenient milking sheds. Farmers have accepted that economic production is possible only with relatively large herds; they are thinking bigger than before. The aim is for herds of 100 or more, instead of the earlier objective of 40 to 50 cows.

To enable herds of this size to be milked quickly, premises must be designed for convenience and to enable cows to be handled without unnecessary movement on the part of the operators.

Also of the greatest importance is the need for the design …

Leaflet No 1000 - Rate Of Milking With Machines - Further Results From Western Australian Herds, R. A. Bettenay

Bulletins 1 - 2999

IN an earlier article by this Department (Vol. XXVI No. 2 PP. 99-104) some introductory remarks were made on a study being conducted on the rate of milking by machine, and preliminary findings were recorded. The conclusion was reached that the rate of milking on most farms was too slow, it being considered that in the vicinity of five minutes per cow should be sufficient under machine milking and that, if the teat cups were left on for a longer period than this, damage to the udder was likely to follow.
