In several lofts with Tippler pigeons in my city, the upper beak becomes longer than normal and turns up like the beak of an eagle?
Dear Madam/Sir,
I have seen this a couple of times, mostly with pigeons that have had an injury on that place or that had this beak problem from youngster. In that case it could be a genetic problem. If a lot of birds of the same bloodline are having that problem I would consider this genetic option. Another possibility could perhaps be circovirus, as this is sometimes associated with feather or perhaps beak problems, but this is only a hypothesis.
Kind regards
My young birds are detoriating, symtoms are losing weight and light green (fresh leave color) watery dropping?
Dear Madam/Sir,
A diagnostic examination of the birds by a veterinarian is important. With the symptoms you describe, there are some possibilities. It is important to know if there is/was any vomiting, problems flying or nervous problem. From the info I have from you I think mainly of adenovirus, paratyphus, endoparasites, perhaps paramyxovirus, streptococcus or another infection. There is also a possibility the young birds are weakened by the circovirus so any infection can cause severe problems, as this virus takes away the pigeon's immunity.
Kind regards
Is there any adenovirus and herpesvirus vaccines available for pigeons? Can we use circovirus and pox vaccines for chickens?
Dear Sir,
There are no such pigeon vaccines available at the moment. The EDS vaccine for chickens has been used with pigeons for adenovirus, but scientifically the efficacity of this is seriously questioned, because the EDS adenovirus is very different to the pigeon adenovirus. The problem with vaccines developed for other animals is that these vaccines are not tested with pigeons for efficacity or side-effects. Sometimes the virus strains can differ a lot from the virus strain that causes disease with pigeons. It could be interesting to test the chicken circo vaccines on pigeons. I don't think it is interesting to use the Marek vaccines (herpes) for chickens, because the virus is quite different.
It is absolutely not advisable to use chicken pox vaccines with pigeons. In some chicken vaccines the original (living) pigeon pox virus is used. This means you would give your birds the pox disease.
Kind regards
My birds have been dying and had diarrhoea from an unknown disease?
Dear Sir, Some of the symptoms are indeed indicative for paramyxo virus. Nevertheless, as you mentioned yellow diarrhoea with birds before they die, I also suspect adenovirus type II. Yellow diarrhoea is a sign the liver is very badly harmed and that's the case with adenovirus type II. The virus even completely destroys the liver. With adenovirus II, there is 100% mortality, this means that if a bird gets sick it will certainly die. Luckely not all the birds get sick. It is not clear why one bird gets sick and the other not. The fact that sick birds also could survive on your loft, indicates adenovirus type II can't be the only problem. It is very possible that the watery dropping are caused by the hairworm infestation and/or paramyxo. The bad feathers could be an indication the young birds are also infected with circovirus. This virus attacks immune cells of the young bird (under 4 months old), this makes them vulnerable for all kinds of infections. It is a major problem this year in Belgium with a lot of deaths in young birds. They can die from ordinary infections like canker, but also from paratyphoid, adenovirus, etc... Certainly do not underestimate the hairworm infestation as it can also be cause of deaths. As for the vaccination for paramyxo, it is advisable to also do this as soon as possible. Kind regards
My birds lost validity, thin, and features. Could you tell what is the cause initially?
It is advisable to let your birds be examined thoroughly for all kind of infestations especially for paratyphoid, worms, ectoparasites, other bacterial problems, viral problems,... Perhaps an autopsy of some infected birds could be of use. I suspect a severe intestinal problem (causing a bad digestion of essential amino acids) perhaps in combination with circovirus could be the initial cause of the feather problems but further examination is advisable.
Wanneer worden jonge duiven ingeënt tegen paramyxo?
het ei en veroorzaakt een vernietiging van het immuun-systeem. In feite is circo-virus de onderleggende oorzaak van ernstige ziektedoorbraken bij jonge duiven, ook adenovirose. Men kan het vergelijken met AIDS bij de mens. Als men vroeg vaccineert heeft men meer kans dat er toch nog een immuniteit opgebouwd wordt. Bij later vaccineren kunnen gevaccineerde duiven, besmet met circovirus, toch nog paramyxo krijgen, dit ondanks de goede vaccins op de markt.
Mijn duiven stoppen met eten, en de spijsvertering stopt. Welke ziekte is dat en wat kan ik er aan doen?
Een mogelijkheid die zeker indachtig moet worden gehouden is circovirose, die de weerstand van de jongen zal gaan aantasten, waardoor de jongen nog extra vatbaarder zijn voor allerlei secundaire infecties zoals Coli, wormen, adenovirose enz....
Zelfs andere ziekten die schijnbaar niet onmiddellijk levensbedreigend zijn, zoals tricho etc, kunnen samen met de aanwezigheid van circovirose een groot probleem vormen.
Indien het circovirose zou zijn, dan is het voornamelijk van belang de dieren zo goed mogelijk te behandelen tegen de secundaire ziektes die eventueel aanwezig zouden kunnen zijn, want tegen het circovirus is op dit moment nog geen wonderproduct beschikbaar.
Een juiste diagnose stellen is echter moelijk enkel en alleen afgaande op de anamnese, ik zou u aanraden een dierenarts te contacteren en eventueel een autopsie te laten uitvoeren zodat u de juiste oorzaak kent van uw probleem, en de nodige zorgen kan toedienen.
