Cattle Stocking Rates In A Higher Rainfall Area, R Sprivulis Jan 1967

Cattle Stocking Rates In A Higher Rainfall Area, R Sprivulis

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

THE 1965 Pardelup cattle stocking rate trial was conducted with Hereford cross yearling steers on annual pasture of Mt. Barker sub. clover, Wirnmera ryegrass and various volunteer annual species.

This was topdressed with 186 lb. of superphosphate per acre in mid March.


Good Management For The Springers Pays Dividends, J Y. Langdon Jan 1966

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 Jan 1966

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.


Meadow Hay For The Dairy Herd, F E. Ryan Jan 1966

Meadow Hay For The Dairy Herd, F E. Ryan

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

CONSERVATION is the basis of progress in dairy farming and the major form is meadow hay, but unfortunately relatively few dairy farmers give enough attention to the quality and quantity of this important feed.


The First Year Of A Cattle Stocking Rate Trial At Pardelup, R Sprivulis Jan 1966

The First Year Of A Cattle Stocking Rate Trial At Pardelup, R Sprivulis

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

AS a first step towards the study of pasture utilisation by cattle, a simple trial was commenced at the Pardelup Prison Farm in 1964.

The trial is carried out with Poll Hereford cross steers set stocked on Mt. Barker subterranean-clover and Wimmera ryegrass pasture.

It will be repeated for several seasons.


Reproductive Wastage And The Sheep Shortage In Western Australia, Department Of Agriculture, Western Australia Jan 1966

Reproductive Wastage And The Sheep Shortage In Western Australia, Department Of Agriculture, Western Australia

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

WESTERN AUSTRALIA has an acute shortage of sheep.

It is estimated that about seven million extra sheep are needed to stock existing pastures fully; meanwhile the carrying capacity of the State's pastures is increasing at the rate of three million sheep a year.


Continuous Grazing On Rose Clover At Northampton, R J. Parkin Jan 1966

Continuous Grazing On Rose Clover At Northampton, R J. Parkin

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

BECAUSE of its upright growth habit, it is often thought that rose clover may require some form of specialised grazing management.

It has also been said that the sheep find the plant and in particular the seed head, undesirable in the dry stages.

However, more recent observations refute this (Bailey 1966). The present commonly-grown strains of rose clover are later flowering generally than the medics or Geraldton subterranean clover and stay green later in the season.


Heavy Rate Set Stocking : Esperance Downs Research Station, R J. Doyle Jan 1966

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.


Egg Shell Quality, R J. Bishop Jan 1966

Egg Shell Quality, R J. Bishop

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

Recent overseas work and local industry developments indicate that the calcium content of feed for laying hens in Western Australia should be increased to achieve satisfactory egg shell strength.

Age, temperature and breeding are other important influences on egg shell quality.


More Sheep Per Acre, Department Of Agriculture, Western Australia Jan 1966

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 Jan 1966

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 Jan 1966

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 Jan 1966

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 Jan 1966

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.


Animal Husbandry Research At Bramley, Department Of Agriculture, Western Australia Jan 1966

Animal Husbandry Research At Bramley, Department Of Agriculture, Western Australia

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

A progress report of animal husbandry investigations at the Bramley Animal Husbandry Research Station, Margaret River.

BRAMLEY RESEARCH STATION is four miles north of Margaret River.

The average annual rainfall of 45 inches falls mainly in the winter, providing a seven-month growing season which starts in March or April.

The June-July period is excessively wet, causing extensive waterlogging of the soils.


Comparisons Of Broiler Rations, D F. Hessels Jan 1966

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?


Stocking Rates With Growing Cattle At Wokalup Research Station, Maurice C. Cullity Jan 1966

Stocking Rates With Growing Cattle At Wokalup Research Station, Maurice C. Cullity

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

CONSIDERABLE attention has been given in Australia and in overseas countries to methods of grazing control, and to the effects of varying stocking concentrations.

There is evidence that the highest yields per animal—of milk or butterfat per cow, or of weight increase per growing or fattening beast—are not necessarily a true reflection of the greatest output from the farm, as indicated by the measure of yield per acre.


Skim Milk : Is A Valuable Pig Feed, But It Should Be Balanced By Other Foods, P Mcnamara, R. Sprivulis Jan 1966

Skim Milk : Is A Valuable Pig Feed, But It Should Be Balanced By Other Foods, P Mcnamara, R. Sprivulis

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

SKIM milk is a source of high quality protein, and as such is a valuable feed for young pigs.

Pigs will live and grow on skim milk alone, but it is not a balanced food. You will not get the best out of the milk or the pigs if the diet is not balanced by other foods.


Production-Line Calf Feeding, F J. Fielder, A. Hamilton Jan 1966

Production-Line Calf Feeding, F J. Fielder, A. Hamilton

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

MANY cream-producing dairy farmers have found that it can be profitable to increase the number of calves they rear. In fact, it is big business for those who can rear up to 200 calves a year, and a few have already achieved this number.


Baby Beef Production In W.A, D J. Barker Jan 1966

Baby Beef Production In W.A, D J. Barker

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

BABY beef should be marketed at about 500-600 lb. liveweight at less than 12 months old, and should be in prime condition to be sought after by the trade.

Dairy Farming In The Busselton-Margaret River District. Part 3. Fodder Conservation, R A. Bettenay

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

An analysis of fodder conservation indicates that farmers in the Busselton-Margaret River district are conserving less than half the amount of fodder considered desirable.—Third in a series reporting a survey of farm practices in the district.


Dairy Farming In The Busselton-Margaret River District. Part 2. Stocking Rate And Production, R A. Bettenay Jan 1965

Dairy Farming In The Busselton-Margaret River District. Part 2. Stocking Rate And Production, R A. Bettenay

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

Survey results suggest that the production of butterfat per acre could be doubled on many farms in the Busselton-Margaret River district.—Second in a series of articles reporting a survey of farm practices on 100 farms in the district.


A Sheep Management Calendar For Lambing On Green Feed, H E. Fels, J. A. C. Smith Jan 1965

A Sheep Management Calendar For Lambing On Green Feed, H E. Fels, J. A. C. Smith

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.


Sheep Can Be More Profitable In The Wheatbelt, G T. Halpin, P. Nelson Jan 1965

Sheep Can Be More Profitable In The Wheatbelt, G T. Halpin, P. Nelson

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

TRADITIONALLY, wheatbelt farmers have looked upon sheep as being subsidiary, or at best, complementary to their main activity, wheat growing.

Because there has been a mistaken belief that clover would not grow, these farmers have depended upon native grasses and crop remains (stubble) for sheep feed, a practice which has put a limit to the number of sheep a property could support.


Rearing Dairy Calves, R A. Bettenay Jan 1965

Rearing Dairy Calves, R A. Bettenay

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

ON Western Australian dairy farms the wastage rate of dairy cows is probably more than 20 per cent, and this, coupled with the tendency towards bigger herds, means that well over half of the heifer calves born should be reared for herd replacements.


Lot Feeding Of Beef Cattle. 4. Cattle For Feed Lots, W J O Wilkie Jan 1965

Lot Feeding Of Beef Cattle. 4. Cattle For Feed Lots, W J O Wilkie

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

BREED, age, condition, health, temperament and sex are all important in feed lot cattle.


Dairy Farming In The Busselton-Margaret River District. Part 4. Pasture Production, R A. Bettenay Jan 1965

Dairy Farming In The Busselton-Margaret River District. Part 4. Pasture Production, R A. Bettenay

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

If deteriorated pasture and underdeveloped pasture in the Busselton-Margaret River district could be improved to the standard of the present highly productive pastures stocking rates could be improved by more than 50 per cent.—final article in a series reporting the results of a survey of farm practices in the district.
