The purpose of this study was to 1) identify microbial compositional changes on chicken carcasses during processing, 2) determine the antimicrobial efficacy of peracetic acid (PAA) and Amplon (blend of sulfuric acid and sodium sulfate) at a poultry processing pilot plant scale, and 3) compare microbial communities between chicken carcass rinsates and recovered bacteria from media. Birds were collected from each processing step and rinsates were applied to estimate aerobic plate count (APC) and C

<i>Campylobacter</i> as an inhabitant of the poultry gastrointestinal tract has proven to be difficult to reduce with most feed additives. In-feed antibiotics have been taken out of poultry diets due to the negative reactions of consumers along with concerns regarding the generation of antibiotic resistant bacteria. Consequently, interest in alternative feed supplements to antibiotics has grown. One of these alternatives, prebiotics, has been examined as a potential animal and poultry feed addit

The objective of the present study was to evaluate the prebiotic ability of Arkansas (AR) LaKast rice bran cultivars as a feed supplement to reduce Salmonella Typhimurium and other gut microbiota. An in vitro mixed anaerobic culture system was used to simulate conditions in the chicken ceca. Anaerobic cultures contained feed, cecal contents collected from 2, 4, and 6 weeks of chicken broilers, and with/without AR rice bran (pureline and hybrid). After 24 h pre-incubation, S. Typhimurium was inoc

Backgrounds: Danggui, one of the major herbs in Korean traditional medicine consists of three species: Angelica gigas of Korea, Angelica sinensis of China, and Angelica acutiloba of Japan. Despite its importance in Korean traditional medicine, recognition of the clinical differences between its three species is insufficient. Objectives: The purpose of the present review is to suggest evidence in using Angelica gigas, Angelica sinensis, and Angelica acutiloba distinctively in clinic, by comparing

본 연구의 목적은 대학도서관의 다양한 활동을 평가하기 위하여 정보서비스의 생산 및 이용의 과정 속에서 2년(1999-2000) 동안의 효율성을 평가하고자 하였다. 효율성 평가에 있어서는 자료포락분석(Data Envelopment Analysis)기법을 사용하였으며, 프랑스의 대학도서관이 가진 환경적 요소는 외생변수로 고려되었다. 실증분석은 서비스의 생산과 이용의 두 측면에서 독립적으로 실시하였으며, 도서관의 효율성 정도는 평가 년도에 따라, 평가 영역에 따라 그리고 도서관의 특성에 따라 다르게 나타났다. 특히, 주제화된 도서관이라 할 수 있는 CADSIT 대학도서관이 일반대학도서관에 비해 서비스의 이용측면에서 보다 효율적으로 나타났다. 그리고 비효율적인 도서관의 비효율성은 투입량의 비효율적 사용보다는 산출량의 생산 부족에서 비롯된 것으로 나타났다.
