Isolation Of Drug-Sensitive Eimeria Species From Wild Turkey Feces And Development Of A Model Bioshuttle Program For Eimeria Meleagrimitis For Domestic Turkeys, Maria Carolina Trujillo Peralta

Graduate Theses and Dissertations

The objective of this thesis was to determine the anticoccidial profile of Eimeria spp. derived from wild turkeys. These drug-sensitive Eimeria spp. have potential to be used as vaccine candidates to control coccidiosis in commercial turkeys. Chapter two consists of a brief literature review focused on coccidiosis in turkeys. Chapter three addresses the methodologies utilized to isolate, recover, and speciate Eimeria recovered from wild turkey feces in the eastern two-thirds of the United States. From this, we successfully obtained single oocyst-derived stocks for E. meleagrimitis, E. dispersa, E. meleagridis, E. gallopavonis, and E. adenoeides. Chapter four describes the experiment conducted …

Coccidiosis Vaccination And Nutrient Utilization In Broiler Chickens, Alyson Elaine Gautier

Graduate Theses and Dissertations

Four experiments were conducted to evaluate the interrelationships among coccidiosis vaccination and nutrient utilization in floor-reared broiler chickens. Experiment 1 longitudinally compared the effects of coccidiosis vaccination and a chemical coccidiostat on broiler performance, nutrient digestibility, and intestinal morphology. Coccidiosis vaccination had no significant impact on morphology, overall body weight gain and feed intake of vaccinated birds, although vaccination impaired overall FCR. Vaccination elicited a transient reduction in digestibility of energy and nutrients, particularly for lipids, but vaccinated birds were able to recover from these reductions by 20 d. Experiment 2 assessed the impact of vaccination in digestibility of different …

Precautions For Day Old Fowl Pox Vaccination, P Smetana

Journal of the Department of Agriculture, Western Australia, Series 4

DURING 1962 day old vaccination was widely adopted as a preventative measure against fowl pox.

From June, 1961, until mid-June, 1962, this procedure proved to be highly successful, but from this date onwards a proportion of treated flocks became affected by breakdowns accompanied by mortality and retarded growth.

In some cases the losses were disturbingly high.

Day-Old Fowl Pox Vaccination, P Smetana

Journal of the Department of Agriculture, Western Australia, Series 4

FOR many years the standard procedure for fowl pox prevention on West Australian poultry farms has been to vaccinate young stock at 12 weeks of age. Although most farmers have used this system successfully it has a number of weaknesses which can be overcome by day-old vaccination.

A new day-old fowl pox vaccine now on the market has many advantages over the normal vaccine, which is used at about 12 weeks old.

In tests at the Poultry Research Station it gave satisfactory results.
