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.

Abstract ▼ AI-Helper 아이콘AI-Helper

With regard to animal welfare concerns, behavioral information of weaned and mixed piglets is great interest in swine production. The aim of this study was to demonstrate the change in behavior of weaned piglets over time in two different groups (littermates and piglets from different litters) after...

제안 방법

  • The behaviors of the piglets in the groups were video-recorded continuously for 9 h per day for 3 consecutive days. All behavioral data were obtained from video images that were digitally recorded from 09:00 to 18:00 h on days 1, 2, and 3 after weaning and mixing. Instantaneous scan sampling was carried out at 10-min intervals.
  • , 2000). In this study, various behaviors were observed in weaned piglets after mixing, such as drinking, feeding, chewing, inactivity, agonistic behavior, locomotion, pen exploration, belly nosing, excretion, and other behaviors. Differences between the control and treatment groups for some behaviors, such as feeding, chewing, belly nosing, and excretion, were subtle in the first 3 days after mixing.
  • However, there is a lack of information on the relation between a piglet’s origin litter and the behavior of individual piglets after mixing. The aim of the present study was to show the change in behavior in weaned piglets over first 3 days in two different groups (littermates and piglets from different litters) after mixing.

대상 데이터

  • Six replicates were evaluated for the control and treatments groups. One wide-angle video camera was installed at the center of the ceiling, so that all the areas of the pen could be observed.
  • The experiment was conducted at the experimental farm of the National Institute of Animal Science in Cheonan (Chungnam Province, South Korea) using 72 pigs (Yorkshire×Landrace).

데이터처리

  • Tukey’s post hoc tests were used to determine pairwise differences between days. Moreover, we compared variables of agonistic behavior between the control and treatment groups for each day using a multivariate analysis of variance (MANOVA). p Values are presented.
  • 5) to achieve normal distribution (Zar, 1999). The behavioral data were analyzed by an analysis of variance (ANOVA). Tukey’s post hoc tests were used to determine pairwise differences between days.
