THE value of management decisions in day-to-day dairy herd management, such as breeding, selection, and culling, depends on accurate identification of individual animals.

A report on tests of some methods of cattle identification available to farmers.

This article is concerned only with methods of identification of cattle on the farm. It is the farmer's responsibility to brand his stock with his registered brand to comply with the requirements of the Brands Act, in addition to any brands or tags applied for his own management purposes.

Any marks other than the registered brand or earmark must be clearly distinguishable from, and …

Grain Finishing Of Beef Cattle Grazing Dry Pasture Or Stubble, D J. Barker

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

WHEAT quotas, poor wool prices and the availability of cheap grain on the farm have stimulated interest in grain finishing of cattle for out-of-season beef production. For many years, Animals turned off in the autumn-winter period have brought better prices than those sold in summer, at the end of the pasture flush.

Feeding grain supplements to cattle on dry pasture or stubble requires less capital than feedlotting and saves the cost of handling and processing roughage.

This article gives the essentials for grain supplementation of dry pasture or stubble but warns that grain finishing is unlikely to be profitable outside …

Feedlots For Beef In W.A. : Some Guiding Principles, D J. Barker

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

FEEDLOTS are small enclosures where all of the animal's feed is supplied from an outside source. Compared with grazing, feedlotting is an expensive method of beef production.

This article gives a guide to the requirements for establishment and management of a farm feedlot, especially the basic equipment and materials, the type of cattle most suited to feedlotting, rations and feeding techniques.

The author warns that skill and experience are needed to run a feedlot and describes feedlotting as an expensive method of beef raising when compared with grazing.

When Is A Cattle Feedlot Profitable?, J T. Stoate

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

THE current surge of interest in feedlots stems from low coarse grain prices and comparatively low early summer baby beef prices. Cattle raisers sense the opportunity for higher prices by holding the cattle on the farm over summer and autumn, and grain producers see better returns from barley and oats fed to cattle than sold as grain.

This article examines the profitability of cattle feedlots and presents sample budgets for two typical situations—the farmer who produces his own cattle but buys grain, and the cereal grower who produces grain but buys in cattle for finishing in a feedlot.

A ready …

Director Of Agriculture Retires, Department Of Agriculture, Western Australia

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

In the June, 1934, issue of the Journal of Agriculture appeared an article entitled "A modified rotation for the wheat belt", by T. C. Dunne and F. L. Shier, which advocated a new rotation of pasture, fallow and cereals to replace the crop-fallow rotation generally used at that time.

Dr. Dunne retired on May 8 after 45 years' service to the Department of Agriculture. He had been Director of Agriculture for more than 10 years.

Basic Pig Breeding, P Mcnamara

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

PROFITABLE pig raising depends on the tumoff of efficiently grown animals. Breeders should be selected for growth rate, and proper care of the breeding sow will ensure that her litters are large and healthy.

A rapid increase in the number of breeding sows in Western Australia suggests that some relatively inexperienced breeders may have started raising pigs. This article sets out the best pig breeding methods as a guide to beginners and a reminder to more experienced pig raisers.

Land Use In Wah Wah And Pine Valleys, Western Utah, Joseph R. Murdock, Stanley L. Welsh

Brigham Young University Science Bulletin, Biological Series

This is a review of the use of public lands in Wah Wah and Pine Valleys in western Utah for grazing of livestock, mining, and other private enterprises. The total area of the two valleys is approximately 1,440 square miles of which about 30 square miles are privately owned. From the time grazing of domestic livestock was initiated in the 1870's and 1880's until 1934, the land was free public domain and was grazed on a first-come, first-served basis. Passage of the Taylor Grazing Act in 1934 ended free use of public lands. Existing evidence indicates that by 1934 the …

Poliovirus Replication: Interactions With Cytoplasmic Membranes And With Compounds Which Affect Virus Biosynthesis, Anne G. Mosser

Student Theses and Dissertations

Picornavirus multiplication is intimately associated with intracellular membranes and affects their production and distribution within the cell. We have shown that the density distribution of cytoplasmic membranes separated by isopycnic centrifugation in discontinuous sucrose gradients is progressively altered after infection of HeLa cells with poliovirus. The most striking change is a very large increase in the smooth microsomal membranes with which viral RNA synthesis is associated. These membranes begin to increase between 2.5 and 3.5 hours after infection, and continue to proliferate late in the virus growth cycle, at a time when cellular protein and nucleic acid syntheses are much …

Nuclear And Plasma Membrane Properties Of Macrophage Heterokaryons And Hybrids, Siamon Gordon

Student Theses and Dissertations

Mouse peritoneal macrophages, which do not synthesize DNA in vitro, were fused with a strain of mouse melanoma cells which proliferates rapidly in vitro. The plasma membrane of the macrophage has specific receptors which enable the cell to ingest antibody-coated sheep red cells and is also rich in a divalent cation dependent adenosine triphosphatase (ATPase) activity. The melanoma cell lacks these macrophage membrane markers. High yields of mouse macrophage-melanoma cell heterokaryons and macrophage-macrophage homokaryons were obtained through the Sendai virus-induced fusion of cells spread on a glass surface. After fusion there was a striking reorganization of cellular architecture by means …

Thinking Of Pigs To Raise Your Income?, P Mcnamara

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

WHEAT quotas and low wool prices have caused many farmers to look to pigs to consume homegrown grain and to lift their incomes. However, with sow numbers at a record level, is it possible for a wheatbelt farmer to raise pigs profitably?

Because of his access to cheap grain, the wheatbelt farmer may be able to make a good profit on each pig sold. This could make pigmeat production a useful sideline on the farm, providing the farmer produces only lean pigs. There is no market for overfat pigs.

This article gives some hints on production of pigs on cereal …

Pheasant Raising, P Smetana

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

THERE has been increased interest in pheasant raising in Western Australia over the past few years, mainly as a result of more sophisticated eating habits and the associated restaurant boom, as well as farmers in country areas looking for more profitable sidelines.

Dairy Calves Can Safely Be Fed Once A Day, R A. Bettenay

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

THE sale of milk rather than butterfat has increased greatly in the past few years and less than half the dairy farmers in Western Australia now own cream separators.

Feeding whole milk once a day can be successful for raising dairy calves, even in winter when calf rearing is most difficult.

A recent experiment at Wokalup Research Station showed that satisfactory weight gains can be achieved if liquid milk is fed only once a day from a very early age. Trial calves gained I lb a head a day over the 12 weeks of the experiment.

Once-a-day feeding greatly reduces …

Responses Of Rumen Microflora To Whey Products Added To High-Grain Low-Roughage Rations, Virgil L. Metzger

Electronic Theses and Dissertations

Many factors present in livestock feeds affect the numbers and types of protozoa and bacteria in the rumen. A small particle size of feed and a fast rate of passage of the feed through the ruminant decreases protozoal numbers. Full feeding of a concentrate ration and an acid pH in the rumen also tend to reduce protozoa numbers. Bacteria numbers tend to increase as the protozoa numbers decrease. Knowledge of rumen microflora population changes on different rations is lacking. It is known that restricted-roughage rations will generally cause lower protozoal numbers. Since whey is an available source of lactose and …

The Lipid Composition Of Milk As Affected By High Grain-Limited Roughage Rations Containing Whey Products, Roger Charles Peper

Electronic Theses and Dissertations

Certain rations fed to lactating dairy cows appear to have a dramatic influence on the lipid composition of milk fat produced. A high grain ration fed with a limited amount of roughage tends to cause a depression in milk fat production while at the same time changing the milk fat composition. There have been various attempts to alleviate the depression in milk fat. Minerals used in the ration seem to slightly relieve the milk fat depression caused by high grain rations. One drawback has been lower milk production due to a decline in concentrate consumption. Whey products added to a …

Effects Of Various Factors On The Rachitogenic Activity Of Isolated Soy Protein, Donald James Arshem

Electronic Theses and Dissertations

The nature of the rachitogenic activity of isolated soy protein was investigated in fifteen studies. A RP-100-glucose purified diet was fed to day-old turkey poults housed in stainless steel batteries. Feed and water were provided ad libitum. Corn, oat hulls, solvent-extracted soybean meal, full-fat extruded soybeans, C-1 protein, casein and texturized forms of soy protein were added to the basal diet at various levels. All feedstuffs were added at two particle sizes: natural form of the feedstuff (>250 u); and ground in a ball mill (<250 >u). The effects of autoclaving for 60 minutes at 120°C were also investigated. …

Effects Of Various Levels Of Dietary Selenium And Arsenic On Chickens, Richard L. Arnold

Electronic Theses and Dissertations

Various levels of selenium and arsenic additions were made to several types of chicken diets to study their effects on growth and reproduction criteria. Three experiments were conducted. The first study involved day-old chicks and terminated at 64 weeks of age. These yearling hens were then used for the second experiments which terminated when the hens were 104 weeks old. The third study was initiated with 20 week old pullets and terminated when they were 52 weeks old. Feeding purified diets resulted in slower chick growth and lower mature body weights of hens. Selenium additions of 2.0 ppm resulted in …
