Tests And Refinements Of A General Structure-Activity Model For Avian Repellents, Larry Clark, Pankaj Shah

Larry Clark

We tested the robustness of a structure-activity model for avian trigeminal chemoirritants. Fourteen benzoates and acetophenones were tested using European starlings Sturn us vulgaris as a bioassay. In general. the pre­ viously proposed model was a reasonable predictor of repellency (i.e., irritant potency). We found that the presence of a phenyl ring was critical to repel­ lency. Basicity of the molecule is the next most critical feature influencing repellency. The presence of an acidic function within the electron-withdrawing functionality seriously detracts from repellency. The presence or absence of an electron-withdrawing or -donating group may potentiate repellent effects, but its presence …

G94-1202 Vaccination Guide For The Small Poultry Flock, Eva Wallner-Pendleton

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide will help the small flock owner decide whether vaccinations might help prevent disease in the flock. Types of vaccines and methods of application are also discussed.

Vaccines are widely used by the livestock industry to prevent diseases. Commercial poultry (farms with greater than 5,000 birds) are almost universally vaccinated against a variety of diseases. Preventative vaccinations have resulted in increased health and improved production efficiency in the poultry industry.
