Study on the Behaviour of Nursing, Rest and Sleep in the Lactating Sow

포유모돈(哺乳母豚)의 포유(哺乳), 휴식(休息) 및 수면행동(睡眠行動)에 관(關)한 연구(硏究)

The present study was carried out to investigate the behaviour of parturition, nursing and sleep with a total of 40 sows and 420 piglets during 28 days from July 6 to August 3, 1984. The results obtained in this study were as follows: 1. About half number of sows employed were recumbent and lay on their right or left side throughout the process of delivery, but the rest changed their lying sides during the delivery, about 65% of piglets born were presented anteriorly. During nursing 51.3% of sows were recumbent and lay on their left side. 2. The entire farrowing process normally lasted 4 hr. Piglets were expelled at an average rate of one for every 19.3mim. 3. The first suckling attempt was observed at about 24.3min after birth. "Teat order" were established within 32hr after birth. 4. The duration and time of nursing were 35.8 second and 24.6 times/day, respectively, in the first day of piglet life. However, they tended to shorten with the advance of lactation. The intervals between nursings were 58.5 min. in the first day of piglet life, but it tended to lengthen with the advance of lactation. 5. The sows were awake for 31.7%. drowsy for 16.7%, and asleep for 51.6% of the 24hr period a day.

본(本) 연구(硏究)는 1984년(年) 7월(月) 6일(日)부터 8월(月) 3일(日)까지 28일간(日間), 분만모돈(分娩母豚) 40두(頭)와 분만자돈(分娩仔豚) 420두(頭)를 가지고, 분만(分娩), 포유(哺乳), 수안행동(睡眼行動)을 조사하고자 실시(實施)하였던 바, 그 결과(結果)를 요약(要約)하면 다음과 같다. 1. 분만모돈(分娩母豚)은 분만시(分娩時) 좌(左) 우(右)로 누워서 분만(分娩)했으며, 분만(分娩)도중 50%는 분만자세(分娩姿勢)를 바꾸었다. 출생(出生) 자돈(仔豚)의 65.5%는 앞쪽으로 출산(出산)하였다. 포유자세(哺乳姿勢)는 좌측(左側)으로 눕는것이 51.3%였다. 2. 자돈분만시간(仔豚分娩時間)은 239.3분(分)이었고, 자돈(仔豚)과 자돈(仔豚)의 분만간격(分娩間隔)은 19.3분(分)이었다. 3. 분만후(分娩後) 첫 번째 젖을 빨려는 시도는 분만후(分娩後) 24.3분(分)이었으며, 젖꼭지 결정시기는 분만후(分娩後) 31.9시간(時間)이었다. 4. 분만일(分娩日) 자돈(仔豚)의 포유시간(哺乳時間)과 포유회수(哺乳回數)는 각각(各各) 35.8초(秒)와 24.6회(回)/1일(日)이었으며, 포유기간(哺乳期間)이 경과할수록 포유시간(哺乳時間)과 포유회수(哺乳回數)가 단축되었다. (P<.01, P<.05) 포유간격(哺乳間隔)은 분만일(分娩日)에 58.5분(分)이었으며, 포유기간(哺乳期間)이 경과할수록 포유간격(哺乳間隔)이 길어졌다. 5. 포유모돈(哺乳母豚)은 하루중 깨어있는 시간이 31.7%, 쉬는 시간이 51.6%이었다.
