The problem can be caused by 15 or more different diseases, all resulting in massive weight loss which is rapidly depleted when a budgerigar is under stress and / or associated illness.

Regular readers are fully aware that we have, arguably, one the world’s finest avian veterinarians at our disposal. I refer, of course, to Dr Rob Marshall. So rather than take non-qualified comments from the editorial desk, please access his full expertise in the following way.

In the above list are articles entitled “Budgerigar Health – Parts 1-5″. These are superb for us amateurs to diagnose problems and narrow down the field of diseases which may be the route you can follow in conjunction with you local veterinarian.

We recommend that you print these articles and put them “on file” so that you can then submit them to your non-avian veterinarian, who can hopefully then supply you with the relevant drug(s). Make sure you take a sick patient with you after reading Dr Marshall’s excellent work.

Please do make use of the “Tags” system to quickly find items of personal interest. It is a very useful addition to this site.

Q. If you were shipping a group of birds abroad, across the USA, or via road, involving a long number of hours in excess of a day, is there any merit in putting them on amoxycillin trihydrate before they leave an aviary to assist with stress?

Similarly, if a breeder was buying a bird in Australia from a top champion in, say, Queensland and driving back to South Australia, would he/she be advised to crop “feed” amoxycillin before departure?

The stresses of such journeys are obvious involving crating, unfamilar noises en route, changes of seed and water on arrival in new premises and the rise in streptococcal infection as a result.

Our resident veterinarian, Dr Rob Marshall, answers as follows:

A. This is a very insightful question.

My approach to this situation is to give “Quik Gel” in drinking water a day before transfer and again via crop needle three hours before departure.

On arrival at the destination, place the birds in a holding cage, separated according to sex.

Monitor each bird closely for signs of acute stress as they enter the cage – i.e. look for pectoral muscle weight loss (see pages 226-7 “The Budgerigar” book) and wet vent (see pages 227-8 “The Budgerigar” book).

If these signs of acute stress are present, then crop feed with food and “Quik Gel” and a penicillin antibiotic (e.g. amoxycillin) and repeat this process for two days.

If no signs of acute stress are found, then give normal food and “Quik Gel” in drinking water for one day, then monitor the birds for five days whilst they acclimatise to their new home.

Note from Gerald Binks:

I cannot speak too highly of Dr Marshall’s book and, in particular, his product “Quik Gel”.

The latter is superb for administering immediately to a sick bird under stress.

My personal use of “Quik Gel” has been outstanding in the aviary, when needed, associated with a heat source.

Full details on “Quik Gel” can be found in this article.

Full details on “The Budgerigar” book can be found in this article.

Both of the above can be obtained online as detailed in this article.

Dear Dr Marshall,

I have seen your articles on the excellent new budgerigar website set up by Gerald Binks. I am hoping you can help me.

I bred three skyblue cocks in 2008. Their sire died at the end of that year and his symptoms were:

• 1. Loss of Weight
• 2. A pulsing in the crop area.

I treated him over a period with tetracycline paste, baytril, megabac and amoxicillin trihydrate. He did not respond and eventually died after 6 months had passed. Now two of his sons have the same weight loss. They are fluffed up and again do not respond to any treatment. They can look fit for a while, but then relapse. There is no nasal discharge. No vomiting, but the faeces are yellowish in colour. Have you any suggestions as to the problem?
(Name and address supplied)

Dr Marshall’s reply:

Weight loss over a prolonged period is consistent with Megabacterial infection. In my book I describe Megabacteria as a secondary disease related to immune suppression. So we have to look for another primary infection which may be a genetic weakness, but more often inherent Polyomavirus infection and / or stress related psittacosis. I would look for the presence of French moult in the stud. Treatment for megabacteria is complicated and requires direct action via crop needle, but the underlying cause has to be identified. Irrespective, the long term approach is to breed away from this line as it is genetically weak.

Fancier’s response:

What do you recommend for treating megabacteria?

Dr Marshall’s reply:

I suggest Fungalin in liquid or tablet form. You need to treat1/4 ml of fungalin liquid with our “Quik Gel”, ER Formula, with a dosage rate of 2.5 mls daily via crop needle for 10 days. After this assess the situation. Often streptococcus is also involved. So an additional antibiotic, e.g. Clavulox liquid 0.1 in the mixture is a help. If good fertility is a problem or patchy, you may have a psittacosis infection which will then be the primary cause and megabacteria the secondary factor because the polyomavirus seems under control.

Fancier’s response:

I have now obtained the fungalin, but in tablet form. How do I mix this prior to inserting it via crop needle as you advised?

Dr Marshall’s reply:

Dissolve one crushed tablet in 10 mls of water. This makes a working solution which you can keep in the fridge. Shake well before use. This should do for a complete course. You can extrapolate the dose down, according to the number of birds involved.

Fancier’s response:

Thank you for your considerable help and advice. It is much appreciated and I have requested Gerald Binks to publish this on Budgerigar.co.uk for the general benefit of the fancy at large.
