Abstract

新生子豚の teat-order 確立に関連する要因を探る目的で, 4腹の母豚を用いて乳頭間における射乳開始時間の差異を測定し, 以下の結果が得られた。(1) 母豚の前方から1番目の乳頭の射乳開始時間は, 3番目の乳頭よりも平均1.6秒早く, 6番目の乳頭よりも平均4.7秒早かった。(2) 射乳開始の時間差と泌乳量との関係は認められなかった。(3) より早く射乳する乳頭を求める, 子豚の吸乳行動が, 子豚の teat-order 確立に直接関連する重要な要因のひとつであると考えられた。

To investigate the factors for establishment of teat-order of newborn pigs, the differences in starting time of milk ejection among teats were measured using four sows.<br>The summary of the results was as follows: (1) The mean starting time of milk ejection of number 1 teat on the most anterior parts of the body was 1.6 seconds and 4.7 seconds earlier than that of number 3 and 6 teat, respectively. (2) There was no correlation between starting time of milk ejection and milk yield. (3) The suckling behaviour of piglets searching for the teat that ejects milk earlier was considered to be one of the factors for establishing the teat-order of newborn pigs.
