复合管理通常是动物研究的一个不可分割的组成部分。需要对许多因素进行评估, 以确保该化合物正确交付。行政路径影响着吸收机制。要引入的物质的特性 (pH 值、粘度和浓度) 可以决定选择哪种管理途径. 12, 3

Procedure

1. 专题应用

  1. 在涂抹任何软膏和药膏之前, 通过使用脱毛奶油或剃须, 将所有皮毛从该区域移走。
  2. 彻底清洁和干燥的皮肤。
  3. 将该物质直接涂抹在皮肤上, 用棉签或直接放置的下落, 以避免技术员的接触。
  4. 为了取得最佳效果, 应用几层薄薄的药膏或奶油, 而不是一层厚的一次性应用。
  5. 用分离的头发涂抹液体, 并在裸露的皮肤上涂抹一滴。
  6. 当在局部应用一种物质时, 由于动物对该区域的梳理, 有可能全身吸收。应采取预防措施, 避免意外摄入或及早清除该物质。小衣领或盾牌可以防止动物到达受影响的身体部位。个人住房也可能需要防止 allogrooming 的笼友。

Application and Summary

最安全和最人性化的复合管理方法是通过口服剂量, 如果有可能将其纳入饲料或水。口服胃是一种精确的配料方法, 但对动物也很有压力, 需要技术熟练。局部管理通常是完成了很少或没有限制的动物, 一旦该地区是适当的准备。仔细考虑政府的路线应该会影响到动物的潜在压力。
