Description

The daily gain of single comb White Leghorn cockerels (35-day-old) were investigated after feeding a diet with Lactobacilus casei or Bacillus coagulans at 0.01% level (10 10/g) for 35 days. Thereafter, the birds were attached the artificial anus, and the digestion trial was carried out using the same diet. The results obtained are summarized as follows : 1) Feeding of the diet added either of both bacteria resulted in a significant increase of daily gain, though the feed intake increased in feeding of the diet with bacteria, so that there was no significant increase in the feed efficiency. 2) When chickens were fed the diet with either of both bacteria the digestibility of crude fat was increased significantly, although digestibilities of the other nutrients were little affected by the dietary supplement of the bacteria. From these results, it may be concluded that the supplement of Lactobacilli to the diet resulted in a stimulation of feed intake, and consequently, the daily gain was increased in chickens.

鶏雛に乳酸産生菌を給与したときの飼料の利用性と消化率を調べるために, 35日齢の単冠白色レグホーン種雄雛に対して, 乳酸産生菌Lactobacillus caseiとBacillus coagulansをそれぞれ0.01%(1×10 10/g)添加混合した飼料で35日間飼育し, その間の増体重・飼料摂取量および飼料効率を比較調査した. さらに同実験終了後これらの鶏に人工肛門の設着手術を施したのち, 乳酸産生菌添加飼料の消化率を測定した。 1) 両乳酸産生薗ともにその添加により有意に増体したが, 飼料摂取量も多かったため飼料効率では僅かによくなる程度であった。 2) 乳酸産生菌の添加はいずれも粗脂肪の消化率が有意に高くなったが, 他の成分では差がみられなかった. 以上の結果, 乳酸産生菌の給与は雛の発育促進と, 僅かではあるが飼料の利用性を向上させる効果が認められた.
