Ua3/3/1 The Economical Approach To Raising Dairy Herd Replacements, With Emphasis On Source Of Protein, Henry Amos, Larry Mutter

WKU Administration Documents

Research project with three objectives:

1. To arrive at the approximate dollar cost of raising dairy herd replacements
2. To determine whether it is possible for the young ruminant animal to utilize non-protein nitrogen to meet part of the protein requirement for growth.
3. To attempt to reduce the cost of raising dairy herd replacements to the College Farm by breeding the heifers to calve at 21-24 months of age rather than the system employed in the past which placed heifers in production at 30-36 months of age.

Fisheries Report No 3 - Western Australian Freshwater Fisheries, Donald D. Francois

Fisheries Research Reports

Most of the Australian States have a comprehensive system of inland waterways, Western Australia, however, is in a less fortunate position. True, the maps of the State show many rivers, but in much of the southern, more populous part, with no summer rain and no winter snow, the majority are virtually a chain of waterholes during the long summer months. At the same time, in a relatively small section in the south-west corner, there is a series of permanent streams flowing through what was originally dense forest. But apart from the three indigenous freshwater crustaceans, the marron (Cherax tenuimanus), the …

Behavior Of The Australian Musk Duck And Blue-Billed Duck, Paul A. Johnsgard

Papers in Ornithology

Sexual displays of the Musk Duck and Blue-billed Duck are described and illustrated. The displays of male Musk Ducks comprise a series of three forms exhibiting increasing ritualization, complexity, and time-interval constancy. All of them have conspicuous auditory characteristics as well as variously conspicuous visual features. Displays in the species appear to have evolved under the influence of intense sexual selection resulting from what is probably a more completely promiscuous mating system than occurs in any other species of Anatidae. These selective pressures have also probably promoted the evolution of such features as large size and extreme sexual dimorphism that …

Down But Not Out [Milk Fever], F C. Wilkinson

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

The five-year-old Jersey cow pictured had calved overnight.

In the previous year this cow had been the highest producer in the herd, so the farmer was very pleased to see she had produced a heifer calf.

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.

Twinning Increases Production, K P. Croker

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

Many breeders claim that twinning causes too many losses among Merino lambs and does not favour breeding for twin lamb production.

But recent experiments have proved otherwise and agricultural scientists now agree that . . .

TWINNING INCREASES PRODUCTION

THE low marking percentages regularly recorded for Merino flocks suggest that the Merino is a relatively infertile breed.

Certainly, lambing percentages are low when compared with those of most British breeds of sheep.

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

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.

Do You Know This Disease [Scabby Mouth], F C. Wilkinson

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

This sheep is showing rather severe lesions of "scabby mouth" a disease widely distributed in both the pastoral and agricultural areas.

Sheep Or Beef Cattle?, G D. Oliver

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

THE present sustained high meat prices and the moderately low wool prices have caused many farmers to think again about the relative profitability of sheep and beef cattle.

With synthetic fibres continuing to threaten the wool price a changeover from sheep to beef cattle must be seriously exercising the minds of many woolgrowers.

Warning : Footrot Threatens South-West Sheep Industry, Department Of Agriculture, Western Australia

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

DURING the past few months footrot has appeared in sheep in the South-West in an area extending from Busselton southwards to Kudardup.

This area has only recently been stocked with sheep which have been purchased from many sources.

It is probable that there were a few "carriers" amongst these introduced sheep, and that under the favourable conditions of the South-West the infection was able to develop and spread and then to declare itself in clinical form.

Piggery Septic System, N E. Macintyre

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

ONE of the problems of intensive houses for pigs is the disposal of the dung and urine.

If proper arrangements are not made to remove this, it soon accumulates in an offensive pile at one end of the piggery, making an excellent breeding ground for flies.

Classing Your Own Clip, J Reilly

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

One of the most important activities in the Australian wool industry is the preparation of the clip for sale.

Many growers class their own clips and due to this practice they can reduce production costs.

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

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.

Alive-Stiff-Dead [Tetanus], F C. Wilkinson

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

Only 12 hours before this photograph was taken the lamb pictured was alive and healthy.

When examined it was very stiff and unable to stand. A few hours later it was dead.

Manure Disposal From Piggeries, P Mcnamara

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

Many new piggeries have been built during the past year as more farmers swing over to intensive housing.

In most cases the problem of effluent disposal has been overlooked. This article shows how some pig raisers are beating the problem.

Myxomatosis : Its Decline As A Killer, C D. Gooding

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

ALTHOUGH nearly every farmer in Western Australia is familiar with myxomatosis, very few landowners really understand the factor causing the disease to spread or, just as importantly, why the severity of the disease is declining.

Mastitis : Modified Teat Cups Give Better Back-Flushing, Department Of Agriculture, Western Australia

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

Back-flushing of the teat cups has not brought the expected reduction in the spread of mastitis in some dairy herds.

Replacement of the conventional nut-and-tail nipple with a special flushing nipple, or use of a one-piece teat cup liner, will ensure that flushing is efficient.

Individual Sow Feeders, P Mcnamara

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

FOOD is the major cost in any pig enterprise and it is particularly easy for waste to occur in the breeding herd.

Individual feeders enable the pigman to feed each sow according to her need, and enable the sows to eat their feed slowly or quickly as they choose.

Hypocalcaemia In Sheep, J Craig

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

Hypocalcaemia can cause trouble among in-lamb and lactating ewes, especially if they are grazing lush pasture or young cereal crops.

Dry sheep can also be affected. The disease can be confused with pregnancy toxaemia.

. . . A timely reminder issued by Senior Veterinary Surgeon J. Craig.

Did This Cause This? [Sarcoptic Mange Of Pigs], F C. Wilkinson

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

The mite on the left was detected by using a microscope with a magnification of 100 times to examine a skin scraping taken from the above pig.

This confirmed the suspicion that sarcoptic mange mites were the cause of the skin lesions.

Beef Cattle And Production In Western Australia, W J O Wilkie

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

IN an article published in the Journal of Agriculture for February, 1963, the growth of the beef cattle population of Western Australia was shown for a number of districts in the State.

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.

Coccidiosis Of Calves, W A. Halhead

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

Coccidiosis is one of the commonest causes of calf loss and debility on South-West dairy farms.

Treatment and control are simple once the nature of the disease is understood.

Salmonella Infection In Farm Animals, F C. Wilkinson

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

FIFTY-EIGHT cases of salmonella infection were diagnosed in farm animals in Western Australia during 1965.

Losses, due to deaths, abortion and ill-thrift on properties where these cases occurred were often substantial and caused the owner financial hardship.

Many more outbreaks of salmonellosis undoubtedly occurred but were not brought to the notice of veterinarians.

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.
