Heat Denaturation Of Serum Proteins In Skimmilk And Whey As Measured By The Harland-Ashworth Test, Lynn Verl Ogden

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Milk serum proteins have been shown by other workers to be partially protected from heat denaturation by the presence of milk solids (8, 15, 16) and whole caseinate (14). This study revealed that some serum proteins (B-lactoglobulin), as shown by the Harland-Ashworth test (14, 17), were more readily denatured in skimmilk than in rennet whey. A comparison of the heat denaturation rate of serum proteins in whey as opposed to those in whey containing 2.5 percent isoelectric casein was also studied. A striking protection of serum proteins seemed apparent in the presence of isoelectric casein. However, it was learned that …

Progress report on a farm scale beef-raising investigation at the Department of Agriculture's Wongan Hills Research Station.

A SMALL herd of beef cattle was established at Wongan Hills Research Station in 1964 and the first crop of calves was dropped in the autumn of 1965. The calves' growth rates were recorded and they were marketed as 18-month-old steer beef in November, 1966.

Plant Vs. Animal Protein As A Source Of Supplemental Protein For The Gilt, Dwane R. Zimmerman, E. R. Peo, Jr., D. B. Hudman

Department of Animal Science: Faculty Publications

Protein of animal origin has frequently been suggested to have greater nutritional value for swine reproduction than protein of plant origin. Moustgaard (1952) reported that gilts fed a diet in which the supplemental protein was of animal origin (soured separated milk) reached puberty earlier and had a greater ovulation rate and greater embryo survival and litter size at 26 to 29 days of gestation than gilts fed a diet in which the supplemental animal protein was replaced with protein of plant origin. Most of the advantage of the animal protein diet was eliminated when the all-plant diet was supplemented with …

Feeding Urea To Dairy Cows, R A. Bettenay

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

IT has been known for some years that the ruminant animal, through the agency of microflora in the rumen, has the ability to use urea as a source of nitrogen, and to convert some of this to protein.

Worms In Sheep. 2. Seasonal Variations In Worm Burdens, R W. Butler

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

The first article in this series described the worms which commonly infest sheep in Western Australia and the symptoms caused by heavy infestations.

This article outlines the effects of seasonal changes on worm burdens in sheep.

AS a basis for planning a worm control programme it is essential to have information on the seasonal changes in worm burdens and on the factors which control these.

In this article, the more important of these are considered.

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.

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 …

A Guide To Pig Feeding, P Mcnamara

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

FOOD is by far the greatest cost in pig production, accounting for between 60 per cent, and 75 per cent, of the total cost, and for this reason it is important that the basic principles of feeding be understood.

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.

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 …

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 …

Immunity To Ostertagiasis In Calves, Leo F. Lejambre

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Parasites are responsible for heavy economic loss to the livestock industry. The losses in cattle due to parasitism can only be roughly estimated, since many cattle do not die or become visibly sick. However, there are more subtle losses such as reduced growth rate, and decreased meat and milk production (Levine, 1961). In 1954 the U. S. Department of Agriculture published an estimate of the losses in agriculture over the 10 year period, 1942-1951. At that time, the best judgement of specialists in the Department of Agriculture placed the annual loss to parasitism in cattle at $19,026,000 of which $8,989,000 …

Studies On Amino Acid Balance In Three Fish Meals, Krachang Wisutharom

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

High levels of fish mean cannot be used in chick diets in the United States because of the relatively high cost as compared to soybean meal. In certain areas or countries where large amounts of fish meal are produced, it may be economically feasible to use fish meal as the major protein supplement in the poultry rations.

Feed consumed by poultry must provide most of the materials the birds need for growth or to produce eggs. Those who formulate feed must select ingredients and combine them in proportions which will allow the bird to grow or produce eggs at the …
