An Inquiry Into The Influence Of Environment On The Incidence Of Poultry Diseases, L. Van Es, J. F. Olney
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The principal purpose of the investigation reported here was to evaluate, if possible, hygienic measures, and in addition to gather whatever information might become available pertaining to the relation of certain disorders to a given poultry population after its exposure to their specific etiologic factors. The experiments were conducted on a piece of ground upon which poultry had not been maintained for many years, if ever.
The Immunizing Value Of Commercial Hemorrhagic Septicemia Aggressins, L. Van Es, J. F. Olney
The Immunizing Value Of Commercial Hemorrhagic Septicemia Aggressins, L. Van Es, J. F. Olney
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
In 1924, Gochenour published the results of certain experiments which tended to show that what he regarded as a specific aggressin possessed an immunizing value against hemorrhagic septicemia. The aggressin he prepared, by the use of a highly virulent strain of Bacillus bipolaris, was described as having adequately protected seven bovine yearlings against inoculations with the same organism which, when injected into four yearlings, used as virus controls, proved fatal to them. Soon after, if not simultaneously with, the publication of the Gochenour articles, hemorrhagic septicemia aggressin was placed on the market and apparently has since then been sold …
The Value Of Commercial Vaccines And Bacterins Against Fowl Cholera, L. Van Es, H. M. Martin
The Value Of Commercial Vaccines And Bacterins Against Fowl Cholera, L. Van Es, H. M. Martin
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
A great prevalence of the disease known as fowl cholera has naturally stimulated an interest in possible means of prevention and especially in those which may bring about a more or less lasting immunity. Vaccines which were favorably reported by some failed utterly in the hands of others, so that on the whole no substantial advantage has been gained. Vaccines and bacterins are nevertheless constantly urged on poultry owners confronted with disease and the Experiment Station is frequently called upon to give an opinion on their value or to recommend any special preparation. In order to comply with those demands …
