Nest And Brood Site Selection And Survival Of Greater Prairie-Chickens In The Eastern Sandhills Of Nebraska, Lars Anderson
Nest And Brood Site Selection And Survival Of Greater Prairie-Chickens In The Eastern Sandhills Of Nebraska, Lars Anderson
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Greater prairie-chickens (Tympanuchus cupido pinnata) are a grassland bird species of conservation concern. Although greater prairie-chickens have declined over much of their range, the Nebraska Sandhills has the largest population in North America. However, the responses of nest and brood site selection and survival to vegetation characteristics are unknown. I studied prairie-chickens on private rangelands in Rock and Brown Counties from 2009-2011. I fitted 139 females with radio collars to locate nest and brood sites and to determine nest and brood survival rates. Females were trapped on leks during the breeding season and I monitored them throughout the …

Physical And Chemical Properties Of Outdoor Beef Cattle Feedlot Runoff, C. B. Gilbertson, J. R. Ellis, J. A. Nienaber, T. M. Mccalla, T. J. Klopfenstein
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Within the past decade, emphasis has been placed on the quality of our environment. Beef cattle feedlots have been singled out as a significant source of environmental pollution. Environmental protection provided by control facilities requires basic knowledge of the physical and chemical properties of feedlot runoff. This bulletin summarizes studies of physical and chemical properties of beef cattle feedlot runoff completed from August, 1968 through December, 1972.

Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The beef cattle industry is experiencing a significant increase in demand for feeder cattle. Current difficulties in obtaining sufficient numbers of feeder cattle on a continuing basis have put pressures on the feeder cattle marketing system that did not exist in the past. Feedlot operators, growers (backgrounders), and cow-herd operators are looking for ways and means of improving the system. Innovations are being tested. Those circumstances prompted personnel of the Agricultural Experiment Stations of Kansas and Nebraska to undertake a joint study of cattle marketing under a Regional Research Project.

Effect Of Fertilization And Management On The Production Of Bromegrass In Northeast Nebraska, G. W. Rehm, W. J. Moline, E. J. Schwartz, R. S. Moomaw
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Several experiments were conducted in northeast Nebraska to determine the effect of fertility and management practices on the production of smooth bromegrass (Bromus inermis Leyss). The effectiveness of the various fertilizer treatments was measured in units of dry matter produced per acre as well as beef produced per acre. Results of these studies showed that the production of bromegrass pastures in Nebraska could be markedly improved through proper fertilization.
Relation Of Heart Girth To Weight In Holsteins And Jerseys, H. P. Davis, W. W. Swett, W. R. Harvey
Relation Of Heart Girth To Weight In Holsteins And Jerseys, H. P. Davis, W. W. Swett, W. R. Harvey
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Body weight is the one measurement most extensively used to evaluate growth, condition, and value for beef, and as a basis for calculating feed requirements for cattle. Weight can be determined readily by scales but unfortunately scales of a capacity adequate for weighing cattle are not always available. Thus there is a real need for a basis of estimating weight from some body measurement that can be obtained easily and at a minimum of cost and time. It is the aim of this study to utilize additional data now available to increase further the accuracy and reliability of estimating weight …
Forty Years Of Dairy Cattle Breeding At The North Platte Experiment Station, Mogens Plum, Myron G.A. Rumery
Forty Years Of Dairy Cattle Breeding At The North Platte Experiment Station, Mogens Plum, Myron G.A. Rumery
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
In 1913 the Nebraska Legislature appropriated $17,500 to establish a Dairy Department at the North Platte Experiment Station. The department's herd was to be used in demonstrating management and breeding practices and as a source of breeding stock. Since the North Platte herd was started, research in the field of animal breeding has developed new concepts in many phases of dairy cattle breeding and selection. The purpose of the present study is to analyze the progress made under a system of dairy cattle breeding and selection carried out according to the principles that dominated 40 years ago. The results of …
The Nebraska Egg Cooler, I. L. Williams, F. E. Mussehl
The Nebraska Egg Cooler, I. L. Williams, F. E. Mussehl
Nebraska Agricultural Experiment Station: Historical Circulars
Every producer knows that heat is harmful to the quality of eggs, and that the first step in holding fine egg quality is prompt removal of the animal heat. The Nebraska egg cooler has been developed for this purpose. Construction costs are moderate, and repeated observations demonstrate the effectiveness of the principle. Its basic factor is the temperature-reducing effect of cool, humid air passing over the eggs, as soon as possible after they are gathered.
Carotene Content Of Native Nebraska Grasses, I. L. Hathaway, H. P. Davis, F. D. Keim
Carotene Content Of Native Nebraska Grasses, I. L. Hathaway, H. P. Davis, F. D. Keim
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The carotene content of twenty-four grasses native to Nebraska were determined at approximately monthly intervals from June to November. While the carotene concentration of most of the grasses was moderately high during the growing season, it declined to a rather low point by late November. With the exception of Switchgrass, Hairy Grama, Little Bluestem and Prairie Dropseed, all of the grasses contained enough carotene to supply the needs of range cattle until late November. However, only eighteen of the grasses still contained enough carotene by the latter part of September to furnish the carotene required by dairy cows. Even as …
Poultry Progress: Our Egg Marketing Job, F. E. Mussehl, H. C. Filley
Poultry Progress: Our Egg Marketing Job, F. E. Mussehl, H. C. Filley
Nebraska Agricultural Experiment Station: Historical Circulars
Eggs are one of the products which Nebraska farm families exchange for the necessities and comforts of life. Although values are measured in dollars and cents, the interest of the producers centers in the amount of useful goods and services that the eggs will buy rather than in the price per dozen or per case. Farmers are interested in a fair exchange value because they wish better homes, better schools, better churches, and better communities in general. In the typical Nebraska community, not only farmers but physicians, merchants, mechanics and school teachers are dependent for their income, either directly or …

Vegetative Composition And Grazing Capacity Of A Typical Area Of Nebraska Sandhill Range Land, A. L. Frolik, W. O. Shepherd
Vegetative Composition And Grazing Capacity Of A Typical Area Of Nebraska Sandhill Range Land, A. L. Frolik, W. O. Shepherd
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The sandhill area of Nebraska occupies approximately 20,000 square miles of the central portion of the state. Being unadapted to cultivation, the land is for the most part still covered with native vegetation. It is utilized primarily for the production of livestock, chiefly cattle. During the period 1931 to 1938 the sandhills carried annually an average of 1,041,000 cattle, which amounted to 31 per cent of the total number in the state. The management practices used in the Nebraska sandhills have gained national recognition as a good example of range conservation in the United States. The purpose of this study …
Fifty Years Of Achievement In Agricultural Investigation, R. T. Prescott
Fifty Years Of Achievement In Agricultural Investigation, R. T. Prescott
Nebraska Agricultural Experiment Station: Historical Circulars
In Nebraska, a hustling frontier state in 1887, the legislature hesitated not at all in taking advantage of the provisions of the Hatch Act, and now that fifty years have elapsed since the Station was founded, seventy-five years since the Land Grant College Act was passed and the U. S. Department of Agriculture established, and almost twenty-five years since the Agricultural Extension Service was added, it seems worth while to present a general summary of achievement within the state. The main object will be to show some of the important things that have been learned through the investigations of the …
Better Sires -- Better Stock: Build Better By Breeding, H. P. Davis
Better Sires -- Better Stock: Build Better By Breeding, H. P. Davis
Nebraska Agricultural Experiment Station: Historical Circulars
Economy and logic indicate that the most satisfactory method of obtaining higher-yielding dairy cattle is to breed them. Nebraska raises the feeds - corn, oats and alfalfa - that will grow dairy cattle and can raise them as cheaply as any region. The method is simple. Use purebred dairy sires on the present cows. By the use of good purebred dairy sires great improvement can be obtained in a single generation.
