Abstract

摂取蛋白質の消化が一時的に抑制される新生子豚の蛋白質代謝の発達機序を明らかにする一環として, 子豚用代用乳に牛乳カゼイン由来のペプチドを添加して初乳無給与の新生子豚を人工哺育し, 発育成績ならびに血液性状に及ぼす影響を出生直後から1週齢まで調査した。供試豚は, 一腹の雑種LWDを生後直ちに無作為に2分し, 子豚用代用乳のみで哺育する対照区に5頭, 牛乳カゼイン由来のペプチドを3.7%添加した代用乳で哺育する試験区に6頭を配置した。血清蛋白質濃度は両区とも出生直後から出生後72時間にかけて増加し, 1週齢で減少したが, いずれの時期においても有意差は見られなかった。しかし, 血清アルブミン濃度は両区とも時間の経過とともに増加し, 試験区は24時間以降で対照区を上回って推移した。24時間および72時間で両区間に有意差が見られた (P<0.05) アルブミン/グロブリン比は, 両区ともアルブミン濃度の増加に伴って高まり, 試験区が対照区を常に上回って推移し, 24時間および1週齢で有意差が見られた (P<0.05)。出生時体重は試験区1.24kg, 対照区1.25kgとほぼ同様の値であったが, 1週齢になると試験区が1.96kgと対照区の1.82kgを上回った。いずれの時期においても有意差は見られなかったが, 1日平均増体量 (出生直後から1週齢まで) は試験区が102gとなり, 対照区の81.4gに比べて有意に高い値を示した (P<0.05)。<br>以上のことから, ペプチドは新生子豚の体蛋白質合成に効率よく利用され, 初期発育を円滑にすることが示唆された。

The peptide (derived from cow milk casein) addition to milk replacer was conducted to research the effect of weight performance and blood condition of colostrum-free piglets by artificially nursing from birth to 1 week.<br>Eleven piglets from one litter were randomly divided into control group (n=5) and peptide added group (n=6). Both of the two group piglets were fed 60g of milk replacer (CP 28.7% as ADM) with or without addition of 3.7% peptide (CP 86.8% as ADM) per head per day through the experimental period. Blood samples were taken at birth, 12, 24, 72 hours and 1 week.<br>Serum protein concentration in both group was increased from birth to 72 hours, and then decreased slightly. Serum albumin concentration, which supplies amino acid to body tissue, was increased linerly in peptide added group as time progressed and significantly higher than that of control group at 24 and 72 hours after birth (P<0.05). The body weights of control and peptide added group were increased from 1.25kg and 1.24kg at birth to 1.82kg and 1.96kg at 1 week of age, respectively.<br>As a result, average daily gain (102g) of peptide added group was significantly Niger than that (81.4g) of control group (P<0.05).<br>In conclusion the results of this study indicate that peptide is efficiently utilized for body protein synthesis and improves weight performance of colostrum-free piglets by artificially nursing.
