Production Of Monoclonal Antibodies Specific For The Gamonts Of Eimeria Tenella, Nancy Carol Larsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Cecal coccidiosis, caused by the protozoan Eimeria tenella, may manifest as a devastating disease in young chickens and result in substantial economic loss for producers. The parasite progresses through a complex life cycle, exhibiting both asexual and sexual (gamont) stages of development. The purpose of this study was to produce a panel of monoclonal antibodies (MoAbs) against epitopes contained on surface antigens (Ags) of the gamonts of E. tenella with the intent of blocking the fertilization process. Gamonts were harvested from infected ceca, partially purified by differential centrifugation throught a discontinuous 5050% Percoll density gradient and used as a …

Some Effects Of Shifting To Conservation Tillage Systems For Intensive Production Of Corn And Soybean, Kenneth L. Wells, H. C. Vaught, David Heisterburg

Agronomy Notes

About three-fourths of Kentucky's cropland base occurs on sloping land with some degree of erosion hazard. During the past decade, production of soybeans and corn increased rapidly in Kentucky, particularly on sloping land. This resulted in severe erosion on many farms, particularly in the "intensive grain producing counties. Much of this field erosion could be greatly reduced by developing a system for each field that would incorporate use of such agronomic practices as sod waterways, no-till planting, contour plowing, minimum tillage, strip cropping, double-cropping, winter cover crops, crop residue management and rotations. It is believed that the current acreage of …

G89-942 Can You Afford To Use Bovine Somatrophin (Bovine Growth Hormone)?, Jeffrey F. Keown

University of Nebraska-Lincoln Extension: Historical Materials

Factors to consider before using Bovine Somatrophin in your dairy herd are covered here.

Much has been written recently about the effect of administering Bovine Somatrophin (BST) to dairy animals. The expected increase in income that could be generated by the use of BST catches producers' attention.

Before any producer uses BST, however, there are a few questions that should be addressed. The most crucial is, "Can BST administration be cash flowed in my dairy operation?"

The answer to this question is dependent on three crucial areas--your current herd average, herd management situation, and the costs involved in the application …
