Trypsin Inhibitor. V. Nutritive Value Of Treated Soybean Oil Meal And Some Characteristics Of The Trypsin Inhibitor In Soybeans, Raymond Borchers, W. E. Ham, R. M. Sandstedt, C. W. Ackerson, R. H. Thayer, F. E. Mussehl

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The marked improvement in the apparent nutritive value of soybean protein after heating has long been recognized. The fundamental cause of this improvement has never been fully understood. Furthermore, commercial soybean oil meal varies considerably in nutritive value although heat treatment is common in most processing plants. Since heating is generally regarded as deleterious to the nutritive quality of protein, the following investigations of various treatments of soybean oil meal are of particular importance in developing a soybean or soybean oil meal of maximum and uniform nutritive value.

A Preliminary Study Of A Physical Basis Of Bird Navigation, Henry L. Yeagley

Papers in Ornithology

The bird navigation theory as presented implies an organ or organs in the bird's physiology which are sensitive to the effect of its motion through the vertical component of the earth's magnetic field and to the effort exerted to overcome the coriolis force, due to the earth's rotation. Both these influences involve a set of lines which together form a navigational gridwork. By correlating its instantaneous land speed with the two above effects, a bird can fly to its home which is a unique point in this gridwork, or to related companion points existing in the gridwork at positions other …

Early Life History Of The Oyster Crab, Pinnotheres Ostreum (Say), Mildred Sandoz, Sewell H. Hopkins

VIMS Articles

The first and second zoeae of Pinnotheres ostreum have been described Hyman (1924). The five crab stages parasitic in the oyster (Ostrea virginica) have been described by Stauber (1945). The present paper is an attempt to plete the knowledge of the development of the oyster crab from the egg to the first crab instar. This work was done at the Virginia Fisheries Laboratory in summer of 1944, under the direction of Dr. Curtis L. Newcombe.

The first Pinnotherid larva to be described was the zoea of Pinnotheres pisum Leach, the British pea crab. This species has three or more zoeae. …

Bin-Cured Versus Field-Cured Alfalfa Hay For Dairy Heifers, Marshal C. Winton

Masters Theses

INTRODUCTION:

This study was undertaken for the purpose of comparing the nutritive value of bin-cured and field-cured alfalfa hay, using actual feeding trials with dairy heifers.

Any study involving the production and preservation of more and better hay has great economic importance. Shepherd and others (21), in discussing the losses of hay from a national standpoint, state that:

The uncertain weather conditions that frequently exist while hay is being made, particularly in the humid sections of the country, are responsible for variations in the quality of the hay and for large losses of nutrients during harvesting. Conservative estimates indicate that …

The Utilization Of Food Elements By Growing Poults, C. W. Ackerson, F. E. Mussehl

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

1. Day-old poults were found to contain an average of 1.28 g nitrogen, 0.18 g calcium and 0.15 g phosphorus. 2. Day-old poults were fed equal amounts of a good growing ration for 52 days. Analysis of these poults showed retention of 42.6 per cent of the nitrogen, 23.4 per cent of the calcium and 31.3 per cent of the phosphorus contained in the ration. 3. Retentions of nitrogen, calcium and phosphorus were on the same order as those obtained in like feeding trials with chicks.

Mattamuskeet: A National Wildlife Refuge, Rachel Carson

United States Fish and Wildlife: Staff Publications

Mattamuskeet, Pea Island, and Swanquarter-- two on the mainland and one on the outermost barrier beach--are three National Wildlife Refuges in North Carolina that provide winter food and shelter for more than 100,000 waterfowl. Ducks, geese, and swans that in summer scatter across the northern rim of the world from Greenland to Alaska come down the sky lanes in the fall and in these refuges find the conditions they need to survive the hard months of winter.

At Mattamuskeet you can see one of the largest assemblages of Canada geese on the Atlantic seaboard and more of that giant white …

Chincoteague: A National Wildlife Refuge, Rachel Carson

United States Fish and Wildlife: Staff Publications

The national wildlife refuge at Chincoteague, Virginia, is one of the newest in a chain of sanctuaries placed along the flight lanes of the waterfowl. Coming down from the north the principal links of the chain are Parker River, Montezuma, Susquehanna, Brigantine, and Bombay Hook. Then from Chincoteague the links run south, through Back Bay and Pea Island, Mattamuskeet and Cape Romain. Chincoteague, like other waterfowl refuges, is needed because birds migrate, and because in so doing they expose themselves to great dangers.

The migration of birds is one of the ancient spectacles of earth, and one of the most …

Parker River: A National Wildlife Refuge, Rachel Carson

United States Fish and Wildlife: Staff Publications

The Parker River National Wildlife Refuge is New England's most important contribution to the national effort to save the waterfowl of North America. Many million Americans have a direct stake in the success of this effort: the 2,000,00o waterfowl hunters, the millions who find recreation and esthetic pleasure in observing and photographing the birds, and all those, whom there is no way of counting, who understand the value of preserving wildlife as part of America's natural heritage.

During the several generations in which the United States has been converted from a land preeminently wild and unsettled into an industrial and …

Life History Studies Of The Mouse, Peromyscus Truei Nevadensis, Lowell S. Miller

Theses and Dissertations

Peromyscus truel's a fairly common inhabitant of the upper sonaranlife zone of the Western States. It is an excellent laboratory anlmal with the limitation that captivity must be accompanied by forced activlty, in order to keep the animals within the limits of normal activity. This mouse is polyestrous and breeds from early spring to late fall. Observations have shown pregnancy in late September and in early February. It is the writer's belief that ovulation in the ovary occurs only when copulation has taken lace, because corpora lutea has only been found in pregnant or lactating females. The evidence is scanty …

A Seasonal Study Of Food Of Some Birds Of The Wasatch Chaparral, Herbert H. Frost

Theses and Dissertations

A seasonal change occurred in the type of food consumed by the birds studied. Plant food was more important in the winter than in the summer. Animal food, except in one species, was found to be more important during the summer months. The most important plant foods determined by frequency and listed in order of their abundance were: Helianthus annuus, Celtis sp., Quercus sp., Polygonum convolvulus, Amaranthus blitoides, Chenopodium album, and Amaranthus graecizans. The most important animal foods based on occurance in stomachs examined were: Coleoptera, Hymenoptera, Lepidoptera larvae, Orthoptera, Undetermined larvae, Diptera, Homoptera, Coleoptera larvae, Araneae, and Hemiptera. Seventeen …

A Study Of A Heron Nesting Colony, Linden J. Leatham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Herons are well known because of their gregarious nesting habits. Like many others of the lower orders of birds they nest together in pure or mixed colonies of many different combinations and under diverse living conditions. The population of different colonies may vary from a few pairs to many thousands of pairs depending upon the nature and extent of the breeding area, the food supply available and the protection afforded either by natural or artificial means.

In Utah and adjacent areas of bordering states, many types of heron associations have been studied and reported by ornithological workers. Breeding colonies of …

Some Microtechnical Experiments And Recommendations Of New Prestaining Techniques, Edward D. Wood

University of the Pacific Theses and Dissertations

The preparation and staining of biological structures for microscopic examination is of extreme importance to the science of biology since almost all phases of biological advance are, at least to some degree, dependent upon microtechnical methods. Nevertheless, research workers and students of biological science are sooner or later impressed with the inadequacy of many of the microtechnical methods used by them and their colleagues. In the field of microtechnique there is difficulty in finding standardized methods which will uniformly bring optimum results. Throughout most procedures there seem to be variables over which no definite controls have been established. Microtechniques have, …

A Survey Of Intestinal Protozoa At The Stockton State Hospital : Stockton, California, Lawrence Melvin Gholz

University of the Pacific Theses and Dissertations

During the past months much has been published in periodicals, especially those of a pictorial nature, which discredits institutions established for the care of' the mentally ill throughout the nation. Many articles have been presented which show an intelligent approach, but the majority of these treatments are by those who are basing too much on a very narrow experience. For example, one news magazine recently printed a picture of a mental patient in institutional garb sitting on a bench in one of the poses most characteristic of a catatonic. The caption of the picture seemed to ignore this significant fact …
