Abstract

豆腐粕の有効利用を促進するため, 豆腐粕に13.7%の大麦と0.7%のプレミックスを加えて調製したサイレージを肥育豚に給与して消化試験, ならびに肥育試験を実施するとともに, 肥育試験終了後に脂肪融点および脂肪酸組成を調べた。体重50kgのLW交雑種を用い, 5日間の消化試験を行った結果, 豆腐粕サイレージ給与区のNFE, 粗蛋白質および粗脂肪の消化率はトウモロコシを主体とした対照区と比較して大きな差はなかったが, 粗繊維の消化率は有意に高かった。肥育試験はLW・H交雑種を用いて3群を設け約16週間にわたって実施し, 飼料給与は1日2回の制限給餌とした。1群は対照区飼料を全期間給与した。2群は1~12週は豆腐粕サイレージを100%, 13~16週は対照区飼料を給与した (豆腐粕サイレージ1区)。3群では1~3週に豆腐粕サイレージを100%, 4~14週の間は豆腐粕サイレージと対照区飼料の大豆粕を大麦に代えた飼料を50% (乾物換算) ずつ, 15~16週には対照区飼料を100%給与した (豆腐粕サイレージ2区)。肥育試験では, 豆腐粕サイレージ1区は全飼料の66%, 豆腐粕サイレージ2区では47%をサイレージで代替した。増体日量ならびに飼料要求率はどの期間においても3区間に差は認められなかった。また, サイレージの嗜好性は極めて良好であった。背脂肪および腎臓周囲脂肪の融点を測定した結果, サイレージ給与区は対照区に比べ, いずれの部位でも有意に低いか低い傾向を示した。脂肪酸組成では, リノール酸およびリノレン酸は有意に高く, また, オレイン酸およびパルミチン酸は低かった。

The fattening and digestion trials were carried out in crossbred pigs by feeding ensiled tofe cake silage with 13.7% of ground barly and 0.7% of vitamin, mineral premix. In the first trial, 50kg of LW crossbred pigs were fed for 5 days either with ensiled tofu cake silage or with a basal diet, in the control condition, containing maize 73.3%, soybean meal 12%, barly 10%, fish meal 2.6%, and others 2.1%. There were no significant differences in the digestibility of crude protein, crude fat or of NFE between tofu cake silage condition and the control condition. However, the digestibility of crude fiber was significantly higher in the tofu cake silage condition than in the control condition.<br>Three experimental groups of LWH crossbred pigs were placed on the fattening trial for 16 weeks. Group 1 was supplied with the control diet throughout the trial term. Group 2 was supplied with 100% tofu cake silage during the first 12 weeks and then was supplied with the 100% control diet from the 13th through 16th week (tofu cake silage 1). Group 3 fed 100% tofu cake silage during the first 3 weeks, 50% tofu cake silage and 50% experimental diet, which contained barley in stead of soy bean meal in the control diet, for the 4th through 13th weeks, and 100% control diet was fed for the last 2 weeks (tofu cake silage 2). There were no significant differences in the average daily gain among three groups at any stage of the trial. In tofu cake silage 1 and 2, 66% and 47% of the total diet were substituted with tofu cake silage, respectively. No differences among the three groups in feed convertion ratio were found throughout the experimental term. High palatability of the tofu cake silage was observed in the pigs. After the fattening trial, melting points of back and kidney leaf fat were either significantly lower or tended to be lower in the pigs fed with the tofu cake silage compared to those in the control diet. Silage feeds caused a higher concentration of linoleic acid and linolenic acid, but the concentration of palmitic acid was lowered.<br>The tofu cake silage led to normal growth, and an increase in unsaturated fatty acid, and to lower melting points of body fat in fattening pigs.
