The W.A. Egg Marketing Board has decided to increase its egg yolk colour bonus from Id. to 3d. a dozen from April 5, at the same time raising the qualifying colour standard.

This article presents an interesting study of the methods and costs of achieving deeper yolk colours.

Why Did These Lambs Die?, Stanley M. Dennis

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

INVESTIGATIONS over the past two years have shown that most lamb deaths in Western Australia occur during the first three days of life, that is, in the critical neonatal period.

Most of the lambs died between 24 and 72 hours after birth.

Plant Nutrition In Western Australia, George Henry Burvill

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

PLANT nutrition is of great practical importance in Western Australia.

Without a well developed fertiliser industry and research and experiments to guide farmers in appropriate fertiliser use the State's agriculture would be very restricted.

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.

Stinkwort (Inula Graveolens Desf.), G R W Meadly

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

THE original home of stinkwort is the Mediterranean region, including northern France. Apparently the first Australian record was at Onkaparinga in South Australia about 90 years ago.

Efforts were made to keep it in bounds during the years immediately following introduction, but it continued to spread and is now f i r m ly established in all agricultural districts of South Australia.

It also covers large tracts of land in New South Wales and Victoria and occurs in most districts of Western Australia.

Ultraviolet Induction Properties Of Salmonella Potsdam Bacteriophages, Berney Roy Neufeld

Loma Linda University Electronic Theses, Dissertations & Projects

Three lysogenic strains of Salmonella potsdam were studied to determine whether or not they were inducible by ultraviolet light under certain conditions. The strains examined were SP3, SP4, and SP9. SP3 and SP4 contained a single prophage each and SP9 contained two prophages P9a and P9c. The ultraviolet light sensitivities of each of these lysogenic strains and the indicator strain SP2 were also examined.

All three lysogenic strains were found to be inducible. SP3 was induced an average of 3.59% and SP4 an average of 2.21%. The difference between the induction percentages of SP3 and SP4 was not statistically significant. …

The Role Of Light In The Regulation Of Cyclical Estrous Activity In Sheep, M. T. Clegg, H. H. Cole, W. F. Ganong

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The widespread existence of biological clocks among animals is documented by a considerable body of evidence. Recently Farner (13) has reviewed this subject covering information on a large variety of animals. In this paper an attempt will be made to restrict most of the discussion to sheep. Experimental data from other species, however, will be cited when it can be usefully related to an understanding of the mechanisms controlling seasonal breeding activity in this species. As far as present knowledge is concerned, the factors regulating or at least monitoring annual physiologic cycles appear to depend greatly upon the influence of …

Evaluation Of Methods For Controlling The Estrous Cycle, William Hansel

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Truly effective estrous cycle synchronization techniques are of great potential value to commercial producers of beef and dairy cattle, sheep, and swine. Many commercial beef cattlemen recognize the merits of using outstanding sires through artificial insemination (AI) to produce greater numbers of faster gaining cattle having the most desirable carcass characteristics. The relatively high heritability of feedlot gains makes this idea particularly attractive. Nevertheless, progress in attaining this goal has been rather slow, mainly because of the practical problems involved in breeding range cattle artificially and the low conception rates frequently obtained. Methods for cycle regulation compatible with the most …

Density-Gradient Centrifugation: Non-Ideal Sedimentation And The Interaction Of Major And Minor Components, Myron K. Brakke, J. M. Daly

Department of Plant Pathology: Faculty Publications

A small amount of southern bean mosaic virus was contained in a narrow zone after density-gradient centrifugation, but in a much wider zone after centrifugation with a large amount of a second virus. Zone-spreading of a major component by non-ideal sedimentation in density-gradient centrifugation can cause zone spreading of a minor component that the major component overlaps.

The Annual Distribution And Stratification Of Phytoplankton At Aurora Lake, Portage County, Ohio, Harold G. Marshall

Biological Sciences Faculty Publications

A 13-month study of a hard-water lake in northeast Ohio has provided a quantitative and qualitative record of the seasonal changes of the phytoplankton. Maximum production occurred during the summer and winter periods. The summer pulse was dominated by the cyanophyte species: Microcystis aeruginosa, Anabaena spiroides, A. circinalis, and Aphanizomenon flosaquae. The dominants of the winter pulse were the diatoms Fragilaria crotomensis and Asterionella formosa, which formed separate peaks under an ice cover in December and January, respectively. The January development extended into March with the highest concentrations for the year Being reached at approximately …

Roles Of Hypothalamus And Hypophysis In The Control Of The Estrous Cycle, A. V. Nalbandov

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The interrelation between the hypothalamus and the anterior pituitary gland has been firmly established. It is not the intention of this report to review the literature on this extensive subject. Such reviews are available in "Advances in Neuroendocrinology" (Nalbandov, 2), and since the time of this publication many papers on this subject have appeared in current journals. For the purposes of the present discussion a few fundamental facts will be restated, but the major part of my presentation will deal with my own views of the research areas which should be of special interest to animal scientists concerned with phenomena …

Hormonal Control Of Reproductive Activity In The Ewe, J. F. Wagner

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

There are many advantages which result from synchronizing the estrous period in a ewe flock. In situations where the ewes are not hand bred to the ram, the synchronization of estrus makes the application of artificial insemination (AI) techniques more efficient. Detection of estrus usually is more reliable in a synchronized flock. Only 3 to 4 days are needed to detect estrus in 90 percent of a synchronized flock, whereas 16 to 18 days are normally required. This allows the AI technician to plan the number of breedings and have semen available. When hormones are given in the feed, an …

Relation Between Use Of Lincomycin And Outgrowth Of Yeast, Howard W. Clapp

Masters Theses

Introduction

The use of antibiotics has increased the average life expectancy of mankind. They have prevented and cured infectious diseases that previously terminated in death. Consequently, recovery is often prompt and complete.

Though a benefit to mankind, the use of antibiotics in the treatment of infectious disease has also been accompanied by new problems. For example, treatment of a primary infection such as a bacterial pneumonitis with a broad spectrum antibiotic, may result in the death of some of the bacteria. More than one species of bacteria, however, are often found in the infected area. If such be the situation, …

Phytotoxic Substances From Soil Microorganisms And Crop Residues, T.M. Mccalla, F.A. Haskins

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The role of organic matter in the growth of plants has been a subject of much investigation and controversy since the sixteenth century. During the early era, decomposition of plant residues and green and animal manures provided a primary source of minerals for plant growth. In addition, beneficial effects on soil structure and water-holding capacity were attribute to the presence of organic matter. With the development of agricultural chemistry culminating in the work of Liebig in the nineteenth century, it was discovered that plants could make satisfactory growth in the absence of added organic matter if suitable kinds and amounts …

Some Factors Involved In Growth And Sporulation Of Pilobolus Crystallinus Tode And Pilobolus Umbonatus Buller, Kenneth L. Poff

Master's Theses

Pilobolus umbonatus Buller and P. crystallinus Tode grew normally in a nitrogen atmosphere but their sporagnia were non-pigmented. When palced in anaerobic jars along with obligately anaerobic and obligately aerobic bacteria, the fungi grew in the range of oxygen concentrations too low for growth of the aerobic bacterium, but high enough to prevent growth of the anaerobe. The fungi did not grow when the oxygen was depleted to the point that allowed growth of the anaerobic bacterium. Catalase was not produced by the hyphae and trophocysts which normally grow beneath the surface of the medium, but was present in the …

A Pilot Study Of The Relation Of Selected Nutritional Factors To Skeletal Age Of Galactosemic Children, Jessie Merle Harper

Loma Linda University Electronic Theses, Dissertations & Projects

A pilot study was conducted in which twelve children with galactosemia were selected to determine if a correlation existed between the dietary intake of calories, protein, calcium and vitamin D, and the skeletal age of each child. The selected nutrients were compared with the Recommended Daily allowances as revised in 1963. The skeletal ages were determined by the standards as established by Greulich and Pyle (36).

The medical records of these twelve galactosemic children were studied for previous data pertinent to their growth and development. The data which were especially emphasized were: nutritional information and skeletal radiological reports. To receive …

A Workshop Plan For Food Service Supervisors In Seventh-Day Adventist Institutions In Mexico, Marian Anne Fedak

Loma Linda University Electronic Theses, Dissertations & Projects

It is desirable in any dietary service to produce high quality and nutritious food within reasonable cost. Any training which the food service supervisor may receive in administration, nutrition and food preparation will aid in achieving this goal. No training program for food service supervisors in Seventh-day Adventist institutions in Mexico has been available. The plan for a two week workshop for food service supervisors was thus developed as a step toward meeting this need.

Principles on techniques of conducting workshops have been discussed.

An investigation was made into Mexican agricultural trends, food habits and nutritional status to present information …

A Study Of The Effect Of Varying Serum Phenylalanine Levels On Changes In Intelligence Quotient, Darlene Imai Manullang

Loma Linda University Electronic Theses, Dissertations & Projects

Data from thirty medical records of phenylketonuric children under treatment were investigated to determine at which serum phenylalanine level (0-3.9 mg. %, 4-7.9 mg %, 8-11.9 mg. %, greater than 12 mg. %) there would be the greatest increase in intelligence. The children involved in the study were divided into the following groups according to the age dietary treatment was initiated: 0 through 5 months, 6 through 11 months, 12 through 23 months, and over 2 years of age.

Among 6 patients who were placed on the diet during the first 5 months of life, it appears that the optimal …
