Avian Medicine: Principles and Applications

Avian Medicine: Principles and Applications
Ritchie, Harrison and Harrison
This highly regarded was developed to provide a definitive reference text that blends the science of health with the art of clinical medicine.
By applying the information presented in the book, the competent avian practitioner will be able to effectively provide the highest quality care for his patients and guide the companion bird client or aviculturist in implementing and effective preventative health programme. Less experienced practitioners can learn basic evaluation, support and surgical techniques while developing an expanded understanding of advanced procedures that can be performed by specialists in avian medicine and surgery.
Avian Medicine: Principles and Application is the essential reference and the most comprehensive why to, when to and how to guide for companion and aviary bird management, medicine and surgery.

125mg of amoxicillin every 12 hours is the dosage for birds. Dosage info for amoxicillin in post 45 of this thread: https://www.backyardchickens.com/t/...oxicillin-dose-for-a-five-pound-brahma-hen/40

I think it's meant to be ~125mg per 2.2 pounds ever 12 hours.

The link I referenced was yours Kathy, showing the drug book page which just gives the dosage as 125 mg every 12 hours. It didn't say per KG or 2.2 lb.

Quote: Okay, I'm really confused... a) says 125 mg/kg q12h PO and b) says 100 mg/kg q8 , IM, SC PO.

This formulary has similar instructions:

Veterinary formula that i have for Amoxicillin/Ampicillin is Birds(passerines & doves)150-200 mg/kg BID(2x daily) other mammals 11-22 mg/kg BID-TID(2-3x daily) and reptiles 6 mg/kg SID-BID(1-2x daily)

This formulary has similar instructions:

-Kathy

@casportpony a) is every 12 hrs and b) is every 8 hrs plus it could be IM (Intramuscular), SC (subcutaneous) or PO (per Oral)

True, but only with an injectable form.

I absolutely agree. Sorry to say but too many make believe vets sometimes. The dosage for Poultry is def 10mg per kg. Various sites show this, one (sadly) experimental for reasons of determining the effect on poultry is this one: I have cut and pasted the bit relevant to this conversation:

Foot of page 455 says:
Amoxicillin is often the drug of choice in those E. coli infections in which multiple bacterial resistance occurs. Thus, in light of the antibacterial activity and spectrum of amoxicillin and the kinetic data obtained in the present study, it appears that a dosage regimen of 10 mg amoxicillin/kg body weight repeated at intervals of 24 h should be adequate for oral medication against systemic infections in poultry. However, further studies of the tissue penetration of this drug, as well as clinical trials are necessary before therapeutic dosage can be predicted with confidence...
