Chapter 168 Avian Techniques
• Hold the bird’s head firmly with one hand, placing the thumb and second finger under the mandibles and the first finger on the crown.
• Restrain the bird in a towel with one hand (see Fig. 168-1); with the other hand, pull down on a gauze loop placed over the upper beak.
• Gently pass a rigid feeding tube (Lafeber Co., Odell, IL) or soft rubber catheter with an attached, gruel-filled syringe from the right side of the mouth into the crop (Fig. 168-4).
• The volume of gruel to be administered varies with the size and age of the birds. Suggested volumes are budgerigar, 1 to 3 ml; cockatiel, 3 to 6 ml; Amazon parrot, 15 to 35 ml; and macaw 35 to 60 ml.
• The same procedure may be used to perform a crop wash for diagnostic sample collection. In place of gruel, instill 0.5 to 1 ml of sterile saline into the crop, then aspirate immediately.
• Approximately 1 to 2 ml of fluids per 100 g of body weight (BW) may be administered; the larger volume is given to smaller birds.
