First Three Year Average Report For The West Australian Random Sample Laying Test Covering The 4th, 5th And 6th Tests, Department Of Agriculture, Western Australia

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

FIRST THREE-YEAR-AVERAGE REPORT FOR THE WEST AUSTRALIAN RANDOM SAMPLE LAYING TEST COVERING THE 4th, 5th AND 6th TESTS

Despite every effort made to provide all entries in individual tests with a uniform environment it is still possible for a particular entry's performance not to be a true indication of its inherent ability.

Random Sample Test results should therefore be viewed on a long term, annual, consecutive basis. If the yearly results for a given hatchery are grouped together and averaged over a period of several years irregularities in performance due to factors other than genetic worth are minimised and a …

An Assessment Of Cattle Husbandry Problems In Western Australia, W J O Wilkie

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

THE science of animal husbandry deals with all those things which affect the welfare and productivity of our domestic animals.

The relative emphasis placed on welfare and productivity depends on whether the animals are kept as pets or for profit.

Annotated Checklist Of The Birds Of San Joaquin County, California, James Leroy Tate Jr.

University of the Pacific Theses and Dissertations

Evaluation of many records is the only way valid judgments can be made on abundance and status. The necessity of obtaining exact dates, localities, numbers, and special weather conditions cannot be overemphasized. For this reason, records in supplement to this list are freely solicited.

The present checklist includes all species and subspecies for which specimens exist. In some instances sight records have been adequate reason for including a species on the list when no specimen existed. Sight records for species which are difficult to identify have been admitted upon careful editing. The author has followed the policy outlined by Griscom …

Beef Cattle Progress Report, E. F. Frolik, H. H. Kramer

Nebraska Beef Cattle Reports

Efficiency of sugar beet farming can be improved by feeding beet top silage to livestock.

In two recent trials at the Scotts Bluff Experiment Station lambs fed unwilted beet top silage as the only roughage gained significantly faster than lambs fed corn silage.

Amounts of concentrates were comparable (Nebraska Experiment Station Quarterly, Fall, 1962).

This experiment compared the feeding value of a complete mixture of unwilted beet tops and concentrate added at the time of ensiling, with beet top silage and concentrate handled separately. A conventional corn silage and concentrate ration was used as a control.

Results showed that a …

Effect Of Amino Acid Supplementation Of Rations Containing Meat And Bone Scraps On Rate Of Gain, Feed Conversion And Digestibility Of Certain Ration Components For Growing-Finishing Swine, W. G. Luce, E. R. Peo, Jr., D. B. Hudman

Department of Animal Science: Faculty Publications

Previous work at this station (Peo and Hudman, 1962) has shown that meat and bone scraps, when fed at levels from 5 to 10% of the total ration, significantly depress rate of gain of growing-finishing swine. Similar results have been reported by Bloss et al. (1953), Terrill et al. (1954), Meade and Teter (1957), and Becker and Jensen (1961).

Sulfur Fertilizers For Alfalfa Production In Nebraska, R. L. Fox, A. D. Flowerday, F. W. Hosterman, H. F. Rhoades, R. A. Olson

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In order to elaborate all aspects of the sulfur problem in alfalfa production, a series of field, greenhouse and laboratory experiments was initiated to determine: 1. The influence of sulfur fertilization on the yield of alfalfa in Nebraska. 2. The influence of sulfur fertilization on the protein, vitamin A, and sulfur contents of alfalfa. 3. The sulfur supplying capacities of various soils under field and greenhouse conditions. 4. The sulfur content of precipitation at widely scattered points in Nebraska. 5. Soil properties associated with sulfur deficiency. 6. Optimum methods for estimating the sulfur status of soils by soil testing. The …

Multi-Timer For Milking Studies, G W R Scott

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

Recent research into milking machine operation has proved that the belief of old-time hand-milkers that fast milking was good milking was soundly based.

In current practice the emphasis is on convenient shed and yard design and systematic routine in handling the cows. This permits a high throughput of cows and a high output of milk per labour unit.

The multi-timer designed and built by Mr. G. W. R. Scott and described in this article will prove most valuable for pinpointing where time is lost.

Piglet Anaemia : An Iron Deficiency Disease, F C. Wilkinson

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

PIGLETS are born usually with only about 40 mg. of iron in their bodies and the sow's milk only supplies about 1 mg. of the 7 mg. needed each day by the piglets.

This means that if the piglets do not get additional iron, the body stores soon become depleted and anaemia occurs at about one to three weeks of age.

Salt Land Survey, 1962 : Report Of A Survey Of Soil Salinity In The Agricultural Areas Of Western Australia, L C. Lightfoot, S. T. Smith, C. V. Malcolm

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

IN Western Australia there are within the agricultural areas about one million acres of salt land, largely within the 14-25 inch rainfall area used for cereal and wool production.

In March, 1962, farmers in 68 shires in the agricultural areas of Western Australia estimated that on their properties 305,270 acres of land previously cropped or sown to pasture had become salt affected. Of this total, 59,203 acres had gone salt in the seven years immediately before the survey.

Agriculture In The Lakes District : Report Of A Survey Of Farm Practices, A W. Hogstrom

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

At the request of the Central South Zone Development Committee a survey which covered 58 farms in the Lakes District was carried out by officers of the Department of Agriculture. Field work for the survey started in 1961.

The Lakes District supports about 70 holdings adjoining a chain of salt lakes to the east of Newdegate and Hyden but west of the No. 1 Rabbit Proof Fence.

The chain of lakes is about 70 miles long running in a N.N.W. to S.S.E. direction. The lakes are O'Connor, Carmody, Hurlstone, Varley, Gulson, Fox, Camm, King, and Pal lamp.

A Bibliography Of Anomalies Of Fishes, C.E. Dawson

Gulf and Caribbean Research

This bibliography was originally intended as an adjunct to the author's current studies of anomalies in marine fish populations. A number of recent notes have shown, however, that present workers are largely unfamiliar with the rather extensive literature on fish teratology in respect to both particular anomalies and their previous recognition in a species or other taxon. There is an evident need for a compilation of the literature and it is hoped that the present work will fulfill its purpose by facilitating current and future studies in this important area of ichthyology.

Characterization Of Staphylococcus Species Isolated From Raw Milk With Special Reference To The Enterotoxigenic Coagulase-Positive Types, Adnan M. Ammouri

Electronic Theses and Dissertations

Numerous reports from many parts of the world have described the occurrence of outbreaks of staphylococcus food poisoning. Some studies have incriminated raw milk as a reservoir of the staphylococcus organisms as the vehicle of transmission. Recently Cheddar cheese has been implicated as the contaminating agent in food poisoning outbreaks traced to dairy products. The frequency of outbreaks of staphylococcus food poisoning has stimulated interest in the characterization of members of the staphylococcus genus. The strains particularly important are those capable of production an enterotoxin. In order to determine the strains of staphylococcus organisms isolated from raw milk which are …

Geological Survey And Appraisal Of The Paleontological Resources Of The Cooper Reservoir Basin, Delta And Hopkins Counties, Texas, Bob H. Slaughter

Fondren Science Series

During May and June, 1964, the Shuler Museum of Paleontology of Southern Methodist University made a preliminary geological and paleontological survey of the Middle Sulphur River within the basin of the proposed Cooper Reservoir. The work was done under the sponsorship of the National Park Service (Southwest Region). The Quaternary deposits of the basin were mapped and tentatively correlated with similar ones previously studied in the valley of the North Fork of the Sulphur River. A molluscan fauna of Late Pleistocene age and bones from sub-Recent deposits were recovered and identified. Recommendations are made for two weeks of preliminary work …

Viral Infections Of Domestic Animals, George A. Young

School of Veterinary and Biomedical Sciences: Faculty Publications

There is a strong tendency in current research on mammalian virus diseases to concentrate on virus activity at a cellular or subcellular level. This trend is summarized adequately by Enders in relation to viral replication as follows: ','The large and ever-increasing volume of published experimental work on viral replication strikingly reveals the central position of this phenomenon in contemporary virological research. There are good reasons, both biological and practical, underlying this intensive effort to understand, i n detail, how a virus particle, without energy transforming apparatus of its own, manages to utilize the metabolic equipment of the cell to produce …

Nest Structure And Flights Of The Ant Formica Obscuriventris Mayr, Mary Talbot

Faculty Scholarship

In southern Michigan the ant Formica obscuriventris Mayr constructs superficial nests under logs and piled-up leaves. Covered runways connect widely spread chambers.In 1962 one colony released approximately 3000 winged ants in 16 flight days between July 27 and August 24th. An estimated 2587 males flew, and the first nine flights were exclusively male. Females took part in six flights, but most (362 of the 422) flew on one day.The best flights occurred when bright sun warmed the ground after cold nights. Males could move out of the nest at 57 [deg]F. and could begin flying at 63 [deg]F. They flew …

The Effect Of Frozen Storage On The Microflora Of Raw Milk, Jaswant Singh

Electronic Theses and Dissertations

The proper handling of milk samples prior to bacterial analysis has been somewhat of a problem to dairy processors of South Dakota. There have been, and still are, many queries by these people about the treatment of o milk sample prior to the determination of a bacterial count. Should the milk samples be frozen prior to determining the number of bacteria? If it is feasible, what effect will the freezing have on the number of bacteria found? No tangible information about this problem has been found in the literature. Standard procedure emphasize mainly the icing of milk sample before analyzing …

Comparative Study Of Milk Quality Tests On Manufacturing Grade Raw Milk, Donald L. Wallace

Electronic Theses and Dissertations

One criterion used to determine the quality of milk is based upon its bacterial content. This immediately emphasizes the problems of determining milk quality. Bacteriological tests are, at best, only estimates of the number or the activity of the organisms present. Since its introduction to South Dakota dairy farms, the bulk tank has continued to increase in popularity. Its increased acceptance has caused new problems in determining milk quality. The bulk tank allows the farmer to cool the milk faster and more efficiently than ever before, thereby limiting bacterial growth. Quality tests should not only differentiate between good and poor …

Predator And Rodent Control In The United States, A. S. Leopold, S. A. Cain, C. M. Cottam, I. N. Gabrielson, T. L. Kimball

United States Fish and Wildlife Service: Publications

In a frontier community, animal life is cheap and held in low esteem. Thus it was that a frontiersman would shoot a bison for its tongue or an eagle for amusement. In America we inherited a particularly prejudiced and unsympathetic view of animals that may at times be dangerous or troublesome. From the days of the mountain men through the period of conquest and settlement of the West, incessant war was waged against the wolf, grizzly, cougar, and the lowly coyote, and even today in the remaining backwoods the maxim persists that the only good varmint is a dead one. …

Three Southeastern Minnesota Lakes As Possible Habitat For Hexagenia Mayflies, James R. Erickson

Journal of the Minnesota Academy of Science

Three small lakes near Winona, Minnesota, were sampled to determine if they supported populations of Hexagenia mayfly nymphs. Hexagenia nymphs were rare in Lake Winona and the Gravel Pit, and none was found in Crooked Slough. A low dissolved oxygen content at the mud-water interface is probably the limiting factor in Lake Winona and Crooked Slough. The limiting factor in the Gravel Pit is probably the bottom type.
