Treatment Effects of Common Melastoma Herb on White Scour in Piglets

[ Objective] To explore the treatment effects of common melastoma herb decoction on white scour in piglets. [ Method] Piglets suffering from white scour were orally given the common melastorna herb decoction and norfloxacin, respectively. [ Result] After the weaned piglets were gavaged medicines, the treatment effect of the common melastoma herb decoction was significantly different from that of norfloxacin （ P 〈 0.05）, and the optimal dosage of common melastoma herb decoction was 20 ml per piglet for treatment. After the weaned piglets were given medicines added in feedstuff, the treatment effect of the common melastoma herb decoction was significantly different from that of norfloxacin （P 〈 0.01 ）, and the optimum dosage of common melastoma herb decoction was 50 ml per piglet for treatment. The preventive effect of the common melastoma herb decoction was significantly different from that of the control group in 35-day＇old piglets suffering from white scour （ P 〈 0.05）, and the optimal dosage of common melastoma herb decoction was 15 ml per piglet for prophylaxis. To mix medicine in feedstuff was the preferred way for the diseased piglets having appetite. [ Cenclusion] The common melastoma herb decoction has treatment effects and preventive effects on white scour of piglets.

中药野牡丹治疗仔猪白痢的效果

[目的]探索野牡丹煎汁对仔猪白痢的防治效果。[方法]用野牡丹煎汁和氟哌酸对仔猪白痢进行灌服、拌料预防治疗试验。[结果]野牡丹煎汁比氟哌酸灌服治疗刚断奶仔猪白痢的效果在0.05水平上差异显著。20 ml/头是该中药煎汁灌服治疗的最佳用药量;野牡丹煎汁比氟哌酸拌料对50日龄仔猪白痢治疗效果在0.01水平上差异极显著。50 ml/头是该中药煎汁拌料治疗的最佳用药量;野牡丹煎汁比空白对照组拌料预防35日龄仔猪白痢的效果在0.05水平上差异显著。15 ml/头是该中药煎汁拌料预防的最佳用药量;对有食欲的发病仔猪,拌料用药是首选途径。[结论]该研究为野牡丹煎汁对仔猪白痢防治研究提供了参考依据和借鉴。

水分胁迫对野牡丹光合生理的影响

对不同土壤水分条件下野牡丹的光合生理特性进行了观测。结果表明,不同水分处理明显影响野牡丹的净光合速率、蒸腾速率和气孔导度。受到水分胁迫时,气孔导度下降是野牡丹光合作用被抑制的主要原因,同时光合色素含量下降也是净光合速率降低的原因之一。野牡丹的叶温、VPDleaf-to-air随施水量的增加而降低。
