연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Influence of Diet Induced Changes in Rumen Microbial Characteristics on Gas Production Kinetics of Straw Substrates In vitro 원문보기

Asian-Australasian journal of animal sciences, v.18 no.7, 2005년, pp.990 - 996

Abstract ▼ AI-Helper 아이콘AI-Helper

The effect of diets varying in level and source of nitrogen (N) and fermentable organic matter on dynamic characteristics of microbial populations in rumen liquor and their impact on substrate fermentation in vitro was studied. The diets tested were straw alone, straw+concentrate mixture and straw+u...

제안 방법

  • Amino acid (Ae) composition : Isolation of bacteria and protozoa from rumen liquor: Rumen fluid was collected from each animal at 11:00, 11:30, 12:00, 12:30, 13:30, 14:30 and 16:30 h.
  • Effect of incoculum, substrate and interaction between both the factors on gas composition and parameter estimates of the model were analysed using randomized complete block design for factor a (inoculum) at three levels with factor p (substrate) a split plot on a with four levels using following model.
  • Samples in triplicate were drawn in 125 ml capacity polypropylene narrow mouth screw capped bottle at 11:00, 11:30, 12:00, 12:30, 13:30, 14:30 and 16:30 h after infusion at 9:00 h and preserved in icebox until processed.
  • Understanding the dynamics of rumen microbes and digestion process on such low nitrogen roughages is very essential. Therefore, this study was designed to elaborate the relationship of diet induced changes in microbial characteristics to gas production kinetics in vitro with diets differing in quality and physicochemical characteristics. 

데이터처리

  • The difference in AA composition of bacteria and protozoa were tested with Student t-test.

이론/모형

  • Correlation between pool size, production rate and turnover time of bacteria or protozoa and characteristics of the model were calculated along with significance test (Snedecor and Cochran, 1967; Das and Giri, 1991).
