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.

Drilled Versus Topdressed Superphosphate For Cereal Production, A Loutit, P. Stallwood, W. J. Cox

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

CEREAL growers in Australia usually use a drill or combine to apply their seed and superphosphate in one operation.

However, during the last few years, there has been a rapid increase in the amount of super broadcast bafore seeding.

Beef Production In A 14 Inch Rainfall District, D J. Barker, H. G. Cariss

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

Progress report on a farm scale beef-raising investigation at the Department of Agriculture's Wongan Hills Research Station.

A SMALL herd of beef cattle was established at Wongan Hills Research Station in 1964 and the first crop of calves was dropped in the autumn of 1965. The calves' growth rates were recorded and they were marketed as 18-month-old steer beef in November, 1966.

A Comparison Of Nitrogenous Fertilisers For Cereals, M G. Mason

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

THE use of nitrogenous fertilisers has become an important aspect of cereal growing in many districts and farmers now have a number of sources of nitrogen from which to choose.

Good Management For The Springers Pays Dividends, J Y. Langdon

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

This article gives a striking example of the advantages of calving cows in good and rising condition—and explains why condition around calving time is so important.

ALTHOUGH most farmers know that cows calving in good and improving condition will give higher yields than those calving in poor condition, few use this knowledge to improve the production from their cows.

Stocking Rates On Cyprus Barrel Medic In The Northern Wheatbelt, R J. Parkin

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

IN May 1963, some three weeks after germination, a 4th year stand of Cyprus barrel medic was stocked with Merino wethers.

These same sheep are still grazing the area after three years.

Heavy Rate Set Stocking : Esperance Downs Research Station, R J. Doyle

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

THIS article describes a stocking rate demonstration in one paddock at Esperance Downs Research Station, using Merino wethers.

Since December 1961, the area has supported 530 to 540 Merino wethers under continuous grazing.

More Sheep Per Acre, Department Of Agriculture, Western Australia

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

In the late 1950's agricultural scientists in Western Australia became convinced that much of the improved pasture in the agricultural areas of the State was going to waste.

The results of the early trials resulted in many farm demonstrations of higher carrying capacities on improved pastures in southern agricultural areas.

Stocking Rates On Light Land : Wongan Hills Research Station, R J. Lightfoot, W. L. Mcgarry

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

THE two most important things that determine the rate of return on invested capital in Merino sheep breeding and grazing are the stocking rate and lambing percentage.

Rate Of Stocking, Rate Of Fertiliser In The Chapman Valley, R J. Parkin

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

THE Chapman Valley embraces a relatively small area of country, following generally the course of the Chapman River.

The Chapman Valley proper extends from just north-east of Geraldton to Nanson, Nabawa and Naraling and includes on its fringes, areas of Narra Tarra, Moonyoonooka and areas west of Nabawa towards Northampton.

The Avondale Stocking Rate Experiment, L D. White, R. J. Lightfoot, R. N. Glencross

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

THERE is now ample evidence that stocking rates well above the usual district levels can be carried in the Avon Valley.

However, many aspects of increasing stocking rates still require investigation, particularly with lambing ewes and young sheep.

Values Of Commonly-Used Protein Supplements In Broiler Rations, D F. Hessels

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

THE performances of broiler flocks in the latter part of 1964 were below standard. Low body weights and a high incidence of gizzard erosion were common on farms.

It was therefore decided to test the biological valuss of the commonly-used protein supplements and also to try to find a correlation between gizzard erosion and any of the protein supplements.

Comparisons Of Broiler Rations, D F. Hessels

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

PELLETS are the most profitable feed for broiler chickens—but when they contain about two-thirds cereal, does it pay a country grower to pay freight on pellets when cereals are plentiful in his district?

Lot Feeding Of Beef Cattle. 2. Some Cost Factors, W J O Wilkie

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

BECAUSE of the difficulties that have been experienced in making lot feeding pay, it is essential to examine cost factors in some detail.

Stocking Rate And Wool Production At Kojonup, Davies H. Lloyd, A. W. Humphries

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

RESEARCH workers in several parts of the world have recognised the overriding importance of stocking rate in raising animal production per acre.

This article describes some of the initial work on the effect of stocking rate on wool production and liveweight change in medium-Peppin Merino sheep.

The work was carried out at the C.S.I.R.O. "Glen Lossie" Field Station at Kojonup, Western Australia.

Pigs Have A Place In The Dairying Areas, P Mcnamara

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

Pig-keeping could become a much more important feature on South-West dairy farms in the future with the enterprise as a definite farm-unit having a considerable effect on income.

There are indications also that the collection of bulk skim milk and whey for pig feeding will increase in the future. This could make way for the efficient specialist operating large pig raising units close to the source of supply.

In this article. Pig Husbandry Adviser P. McNamara, B.A. (Cantab.) examines pig-keeping in the South-West and makes suggestions on the part that pigs can play on the modem dairy farm.

Ewe Nutrition Before And During Mating, H E. Fels

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

Lambing percentages depend partly on the condition of ewes at mating. If it is practicable, ewes should be allowed to gain condition in the months before mating.

Where this is not practical and ewes are in a store or backward-store condition at mating, flushing should improve their fertility.

Weaner Feeding Practices Need Review, W L. Mcgarry, R. J. Lightfoot

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

Many fanners feed large amounts of grain to their weaners over summer and autumn, in the belief that this is necessary for high lifetime production.

The economics of this are open to doubt; in fact, the results of a recent experiment at Wongan Hills Research Station suggested that weaner feeding practices need review.

Why Poor Prices For Pigs?, P C. Beck

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

A rapid increase in pig numbers and an unfavourable export situation have precipitated the present depression in the pig industry. Concentration on quality production and a gradual reduction in numbers should bring back a more stable situation, says Dairy Division pig specialist P. Beck. Big fluctuations in the pig population—the basic cause of cycles of boom and depression in the industry—would be avoided if more farmers adopted a fixed farm level policy towards the industry.
