Phalaris Staggers : Prevention By Cobalt Bullets, Bryan J. Gorddard, P. P. Mann, A. J. Hadlow

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

FARMERS in the south west of Western Australia are familiar with the use of cobalt for the prevention of ill-thrift and deaths due to cobalt deficiency in sheep and cattle.

Less common is the use of cobalt for the prevention of chronic phalaris poisoning, known as phalaris staggers.

This condition is well known in eastern Australia, but only isolated cases have been recorded in W.A. no doubt due to the relatively small area sown to phalaris in this state.

Growth rate is reduced to the same extent by rubber rings as by the knife.

Sympatry Changes And Hybridization Incidence In Mallards And Black Ducks, Paul A. Johnsgard

Papers in Ornithology

Changes in general fall and winter distributions of Mallards and Black Ducks over the past century have resulted in markedly increased sympatric contact during pair formation between these two forms, and have been responsible for increased opportunities for hybridization. Bureau of Sport Fisheries and Wildlife records of hybrids from 34 states indicate a minimal current hybridization rate that is about 4% of the frequency expected on the basis of mating according to mathematical probabilities of chance contact. Thus, hybridization is most frequent where both forms are almost equally abundant, indicating that no reinforcement of differences reducing hybridization in the primary …

1967 Beef Cattle Progress Report Of Research Activities, E. F. Frolik, H. W. Ottoson, J. L. Adams

Nebraska Beef Cattle Reports

Oral feeding of stilbestrol or implanting with stilbestrol or Synovex has resulted in increased weight gain and efficiency of gain for cattle fed finishing rations.

Combining oral feeding or stilbestrol with implanting did not give increased performance above that obtained from oral stilbestrol alone in two tests. Implanting cattle fed oral stilbestrol at the start of the feeding program with either stilbestrol or Synovex gave a similar pattern of performance to that obtained from oral stilbestrol alone.

Effect Of Plane Of Nutrition, Sex And Bodyweight On The Chemical Composition Of Yorkshire Pigs, G. M. Babatunde, W. G. Pond, L. Dale Van Vleck, G. H. Kroening, J. T. Reid

Department of Animal Science: Faculty Publications

An experiment was carried out involving the full- vs. limited-feeding of 9 pairs of gilts and 6 of barrows from a population of closely related Yorkshire pigs from approximately 45 kg. live weight up to each of three predetermined slaughter weight groups (79, 90 and 102 kg.). The objective was to determine the effects of level of feed intake, sex and weight on the chemical composition of the empty body, edible carcass and inedible parts (offal) and the fatty acid composition of the mid-back fat. As the slaughter weight increased, the percentages of empty body, carcass and offal protein and …

The Effects Of Shearing Time And Stocking Rate On Wool Production, R J. Lightfoot

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

THE results of the first experiment comparing "autumn" versus "spring" shearing over a two-year period were published in 1960.

In this experiment the autumn-shorn ewes cut heavier greasy fleeces (even though they also reared considerably more lambs) with less tender wool, resulting in a higher average return per head from this group.

The autumn-shorn wool carried more seed, was less attractive and contained relatively more pieces than did the spring-shorn wool.

Hydatid Disease In Western Australia, K J. Austen

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

BECAUSE hydatid disease is a disease of humans as well as animals every consideration must be given to its control and to the prevention of any possible increase in incidence.

The incidence of hydatids in Western Australia has not, in the past, been very high.

However, the great increase in sheep numbers which has taken place in recent years and which is expected to continue for many years to come, will produce a situation where it could be expected that the incidence of the disease will rise unless stock owners, particularly sheep owners, take appropriate steps to control the tapeworms …

Availability Of Niacin In Corn And Milo For Swine, W. G. Luce, E. R. Peo, Jr., D. B. Hudman

Department of Animal Science: Faculty Publications

Niacin has been recognized for several years as a dietary essential for swine. Its presence in feedstuffs is well known, but the biological availability of niacin in certain cereal grains commonly fed to swine has not been clearly established. Research has been reported indicating the niacin of white corn and wheat is largely unavailable to the pig (Kodieek et al., 1956; Kodicek et al., 1959 and Luce et al., 1966). Several workers have also obtained evidence that the niacin of corn is in a bound form and largely unavailable to the rat. (Laguna and Carpenter, 1951; Pearson …

Influence Of A Dietary Supplement Of Lysine Feed At Two Levels Of Protein On Growth, Feed Efficiency And Carcass Characteristics Of Swine, M. H. Jurgens, D. B. Hudman, C. H. Adams, E. R. Peo, Jr.

Department of Animal Science: Faculty Publications

Mertz et al. (1949) demonstrated that lysine is essential in the nutrition of swine. Since then considerable research has been conducted to determine the level of lysine needed to promote optimum growth and feed conversion in swine. Recent investigations (Crum et al., 1964; Wallace et al., 1964; Jensen et al., 1965) have been designed to measure the physical and chemical changes in the animal body which may accompany observed differences in performance due to varying lysine and protein levels.

Comparison Of Two Cultures For Use In Preacidified Skimmilk For Cottage Cheese Manufacture, Daryl D. Boddicker

Electronic Theses and Dissertations

Curd formation in a cultured dairy product is brought about by the addition of a bacterial culture capable of producing lactic acid from lactose. The primary function of this culture is to produce sufficient lactic acid to cause coagulation of the caseinate system of skimmilk. A secondary function of the culture is the production of flavor compounds considered to be desirable in these products. The flavor compounds produced by the normal growth of citric acid fermenting organisms are water soluble, and are largely removed during washing of the Cottage cheese curd. Therefore, flavor compounds are normally added to the cheese …

The Influence Of Artificial Insemination In Three Midwestern States, Wendell Lee. Kucker

Electronic Theses and Dissertations

Increased productivity of dairy cattle depends in part upon genetic changes brought about by select ion. Because of the long generation interval and low reproductive rate, genetic improvement in dairy cattle is slow. For this reason, the accuracy and effectiveness of selection of sires is of utmost importance. Selection of sires plays a major role in the genetic improvement of dairy cattle since a sire can leave many more descendants than a female. Consequently, the use of outstanding males is important in the genetic advancement of the dairy cattle population in the upper mid west as well as throughout the …

Consumer Evaluation Of A New Low-Fat Spread-Type Dairy Product, Walter W. Wosje

Electronic Theses and Dissertations

For many years the dairy industry has been going through transitional period whereby many marketing and structural changes have resulted. Generally speaking, these changes have been advantageous to the dairy farmer. During the past years there has been a widespread and increasing interest in profitable means of utilization of dairy by-products. Because of their unique and high nutritional value, the most logical method of disposition of these by-products is, from the standpoint of the general welfare, in human food; generally this is also the most gainful method. The high nutritional value of these products also makes them valuable in feeding …

Digestibility Studies With Western Wheat Grass, Marvin John Wurster

Electronic Theses and Dissertations

In order to make the most economical usage of our range forages it is essential that we know when the forage is most digestible in order for livestock to obtain maximum benefit from it. For many years cutting date has been the most common measure used to determine when a forage contains the most nutritive value. In many grasses emergence of the seed head or seed maturity has been used to determine when a particular forage should be harvested, However, western wheatgrass (Agropyron mithill) is not dependent on seed for reproduction and under range conditions often does not produce a …

Studies On The Effects Of Toxic Materials On The Respiration Rate Of Tubificidae, Richard A. Sikora

Masters Theses

A study was made to determine the effect of lead, nickel and pentachlorophenol, at varying pH levels, on the respiration rate of this family of aquatic oligochaetes. Respiration was measured as the ul. of oxygen consumer per mg. of live tissue per hour of exposure.

Worms were found to decrease their rate of respiration in the presence of lead nitrate. This was demonstrated at three pH levels: 6.5, 7.5 and 8.5. It was concluded that this drop was due to the action of lead on the enzymes of the metabolic systems and on the characteristic of lead which stimulates the …

Factors Affecting Body, Texture, And Water Holding Capacity Of A New Low-Fat Spread-Type Dairy Product, Basil K. Dalaly

Electronic Theses and Dissertations

At the South Dakota State University Dairy Science Department, a challenging work is being conducted to develop a new spread type· dairy product which is made almost entirely of dairy ingredients. It contains about 40% fat, 6% protein, 40% water, and 1.9% salts. Among the problems which faced the workers on this project were the process induced changes in the protein and the water holding capacity, which are interlinked. The problem of water holding capacity is increased by the high water content of the product compared with butter, which contains about 16% water. Maintaining the stability of the fat emulsion …
