Abstract

ウェットフィーディングを離乳子豚へ適用した場合の効果と問題点を明らかにすることを目的に, 本飼養法が離乳子豚の発育, 飼料摂取量, 水消費量および採食行動に及ぼす影響について, 離乳子豚113頭を用いた3回の飼養試験により検討した。給餌器は, 子豚用従来型5頭口不断給餌器 (対照区), 自然落下型1および2頭口ウェットフィーダー (ウェット1-1, 1-2区), 飼料切出し型1および2頭口ウェットフィーダー (ウェット2-1, 2-2区) の5機種を供試した。試験豚を各区へ配置して2~7日間の予備飼育 (馴致期) の後, 人工乳Bで前期3週間, 子豚育成用飼料で後期3週間飼育した。増体に及ぼす給餌器の影響には有意差は認められなかったが, 馴致期ではウェット1-1, 2-1および2-2区が対照区に較べ劣る傾向にあった。しかし, 前期および後期3週間ではいずれもウェット各区が良好な傾向を示した。飼料摂取量はウェット各区が対照区よりも5~8%有意に増加した。飼料要求率には区間の差は認められなかった。水消費量はウェットフィーダーの機種により異なり, 3~31%の節水効果が認められた。採食行動では, 総採食時間および平均採食時間とも, ウェット各区は対照区よりも有意に短縮した。平均飼槽利用率は, 1頭口飼養頭数10頭の場合, 対照区よりも有意に高まった。

Three rearing tests were conducted to determine the effectiveness and to identify the problems of applying wet/dry feeding to 113 postweaning pigs whose feed was changed, one week after the weaning, from the starter milk A to the starter milk B. The effects of wet/dry feeding for postweaning pigs were observed on growth, feed intake, water consumption and eating behavior. Five types of feeders were tested: Conventional ad libitum feeders for growing pigs with five feeding spaces (Control Section); ledge type wet/dry feeders with one feeding space and two feeding spaces (Wet Feeder Section 1-1 and 1-2 respectively); nose operated flap type wet/dry feeders with one feeding space and two feeding spaces (Wet Feeder Section 2-1 and 2-2 respectively). After the postweaning pigs for the test were introduced to each section and reared for 2 to 7 days for preliminary rearing (adapting period), they were supplied with the starter milk B for the first three weeks, then with formula feed for growing pigs for the next three weeks.<br>Effects of the feeder type on the average daily gain of the postweaning pigs were not significantly different across the sections, although the pigs in the wet feeder sections tended to show rather poor growth in 1-1, 2-1 and 2-2 in the adapting period, while they indicated the superior one through the experimental period, compared with those in the control section. The feed intake was increased in wet feeder sections from 5 to 8% compared with the control section. As for the feed conversion, no difference was shown between the sections. The water consumption varied according to the types of wet/dry feeders, showing the water saving effect of 3 to 31%. In the eating behavior, the total eating time of a day and the average eating time were significantly reduced in the wet feeding sections compared with the control section. The feeding trough usage rate, when the number of pigs per feeding space was 10 in the wet feeding sections, was significantly increased compared with the control section.
