Development and Evaluation of a Commercial Direct-Fed Microbial (Zymospore) on the Fecal Microbiome and Growth Performance of Broiler Chickens under Experimental Challenge Conditions.

Direct-fed microbials (DFM) are added to broiler chicken diets in order to promote the proliferation of beneficial intestinal bacterial populations, which may lead to gains in performance efficiency and, potentially, reduce the level of enteric pathogens in the broiler chickens. The selection and laboratory evaluation of strains as well as the experimental trial results of a novel -based commercial DFM product are described. Fifteen wild-type strains were characterized and assayed for their enzyme production capability, spore resistance to pH, salinity, and temperature, and ability to inhibit the growth of and spp.

Evaluation of a subunit vaccine candidate (Biotech Vac Cox) against Eimeria spp. in broiler chickens.

This study evaluated growth performance and cross-protection against Eimeria spp. using a subunit coccidia vaccine in 2 independent challenge experiments. In both trials, chickens were challenged with E.

Assessment of Novel Water Applied Prebiotic to Evaluate Gut Barrier Failure and Performance in Two Commercial Trials in Brazil. A Pilot Study With an Economic Perspective.

The present study evaluated the effect of administration of a water applied prebiotic on gut barrier failure (Experiment 1) and performance in broiler chickens under commercial conditions (Experiment 2). Experiment 1, one thousand four hundred and forty day-of-hatch Ross broiler chickens were assigned to one of two experimental groups ( = 30 replicate pens/treatment; = 24 chicks/pen). Birds in the treated group received the prebiotic orally in the drinking water (0.

Evaluation of a Novel Mucosal Administered Subunit Vaccine on Colostrum IgA and Serum IgG in Sows and Control of Enterotoxigenic in Neonatal and Weanling Piglets: Proof of Concept.

The purpose of the present study was to evaluate the ability of a novel experimental subunit vaccine (ESV), induce colostrum IgA and serum IgG in sows, and to control enterotoxigenic (ETEC) disease in neonatal and weanling piglets. The vaccine was tested in three experiments. Experiment 1 consisted of two independent trials.

CHAMBER: A Regional Performance Improvement CME Initiative for Breast Cancer Health Care Providers.

CHAMBER was a regional educational initiative for providers of care to patients with HER2+ breast cancer. The study goals were to (1) enhance testing for HER2/neu overexpression in patients with invasive breast cancer; (2) increase the appropriate use of targeted therapy for patients with HER2+ breast cancer; and (3) enhance patients' coping ability. This Performance Improvement Continuing Medical Education (PI-CME) initiative included clinical practice assessment, educational activities, and reassessment.

VISION: a regional performance improvement initiative for HIV health care providers.

Introduction: VISION (HIV Integrated Learning ModuleS: Achieving Performance Improvement through CollaboratiON) was a regional performance improvement (PI) continuing medical education (CME) initiative designed to increase guideline-conforming practice of clinicians who manage patients with HIV infection.

Methods: The 3-part activity consisted of (1) clinical practice assessment and development of an action plan for practice change, (2) completion of relevant education, and (3) reassessment.

Results: The activity did not change practitioners' performance in clinical status monitoring and in patient treatment, in large part because guidelines were being appropriately implemented at baseline as well as after the educational intervention.
