Relation Of Heart Girth To Weight In Holsteins And Jerseys, H. P. Davis, W. W. Swett, W. R. Harvey Jan 1961

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 May 1956

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 …


Carotene Content Of Native Nebraska Grasses, I. L. Hathaway, H. P. Davis, F. D. Keim Oct 1945

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 …


Better Sires -- Better Stock: Build Better By Breeding, H. P. Davis Oct 1924

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.
