合成抗菌剤飲水投与による哺乳子豚の増体効果を明らかにする目的で, スルファモノメトキシンとオルメトプリム (SO) 合剤の0.2%水溶液 (6腹54頭) と対照液 (水: 3腹27頭) を子豚用飲水器を用いて1日齢から28日齢の子豚に自由飲水させ, 臨床症状, 63日齢までの増体量およびトキソプラズマ原虫, <i>Boldetella bronchiseptica</i> および <i>Actinobacillus pleuropneumoniae</i> 血清型2 (APP II) の血清抗体価を調査し比較検討した。その結果, SO合剤投与子豚では下痢, アイパッチは発現せず, 有意な増体が認められること, APP IIの陽転率が低いことが明らかとなった。それゆえ, 哺乳中の子豚への自由な合成抗菌剤飲水投与法は, 母豚由来の細菌による下痢症等を予防し, 増体させるには有用な投与法と考えられた。
In order to clarify the effects of synthetic antibacterial agents mixed into drinking water on body weight gain in suckling piglets, Sulfamonomethoxine and Ormetoprim (SO) were used. Drinking water added SO diluted to 0.2% was provided to 54 piglets from 6 litters in the medication section and water was given to 27 piglets from 3 litters in the control section. The piglets were given water or SO mixed into water with ad libitum drinking at 1 day to 28 days using the water vessels for piglets. Clinical symptoms were examined together with body weight gain of 3 to 63 days and at shipping. As for the inspection of antibody in the blood a <i>Toxoplasma gondii, Bordetella bronchiseptica</i> and <i>Actinobacillus pleuropneumoniae</i> serotype 2 (APP II) were investigated. The piglets given liquid with SO showed better results in some aspects; diarrhea and eye patchy did not develop, body weight gain at 3 to 63 days as well as at shipping were recognized to be significantly high, and the changed positive rate of APP II was low. These results, therefore, suggest that ad libitum oral administration of the synthetic antibacterial agents mixed into drinking water prevents suckling piglets from diarrhea by the bacteria of mother sow origin, and that the method is effective in the body weight gain.
