The preceding dietary regimen has been designed to complement our
available enclosures that can accom
modate 25 to 30 four month old ostrich chicks. It is intended to: 1) prevent a skewed growth pattern bet ween total body weight and
musculoskeletal development by
gradually increasing protein and calorie intake; 2) prevent nutritional
myopathies by providing protective levels of Vitamin E and selenium; and 3) prevent rickets and perosis by supplementing the diet with vitamins and minerals (oystershell and
Vitapol? ). This regimen has effec
tively reduced our incidence of
angular limb deformities from 30% to less than 5 %.
A further important preventive medicine procedure for ostrich chicks
is vaccination against pox in the first week of hatching. We use a modified live virus fowl pox vaccine at the
recommended poultry dosage, ad
ministered in the wing web. ? C. Douglas Page, DVM, Jackson ville Zoological Park, Florida
Atoxoplasmosis in the Greenfinch
The "going light" syndrome in the captive bred greenfinch (Car
duelis chloris) in Britain appears to be associated with atoxoplasmosis or
Lankesterella, commonly seen in canaries in continental Europe. The incidence appears to be highly species specific. Breeders have noticed the disease occurs in all mutations of
greenfinches (lutinos, etc.), but it doesn't occur in greenfinch mules
(cross between canaries and greenfin ches) or hybrids with other finch
species.
Young birds begin to show clinical
signs of illness at weaning age when
they're starting to feed on the
ground of the aviary. Upon necropsy, Lankesterella lesions are evident in the spleen and liver. There may be similar diseases in other species of
finches. The prevalence in the wild
greenfinch is unknown. ? Andrew Greenwood, MRCVS,

Aspergillosis Incidence in
Penguins Wild-caught penguins imported by
zoos from South America, South Africa or Antarctica are extremely susceptible to aspergillosis after arrival or at subsequent moves. On the
other hand, newly acquired zoo
captive-reared penguins do not come
down with aspergillosis unless the
challenge is exceptionally heavy (e.g., poor managment conditions with
mouldy vegetation or straw ground
cover). Prophylactic therapy with ketoconazole is recommended for
newly imported birds. ? Andrew Greenwood, MRCVS,

Malaria Prevention in Penguins To prevent malaria in captive
penguins, we recommend the use of human anti-malaria drugs such as
chloroquine. The preventative is ad ministered at the human dosage
(0.75 mg/kg once weekly) during the warm weather months, i.e., from
April /May to September/October in locations the latitude of Britain and
Europe. ? Andrew Greenwood, MRCVS,
Keighley, West Yorkshire, England
Care of Flamingo Feet The primary factor in preventing
cracked feet in flamingos appears to be texture of the substrate of pond bottoms and shores. The use of soft
clay and grass is recommended. Ad
[ justments in the diet to prevent this
j from occurring, such as biotin or
Vitamin A supplementation, have made no difference. Concrete appears to be the worst substrate. It would
probably also be advantageous for
flamingo exhibits to contain brackish water.

Live Food Warning Severe signs of ataxia, dyspnea,
and weakness were noted in flights of
Dybowski Twinspots, Black-cheeked
Waxbills, and Purple Grenadierr ap
proximately 30 minutes after being fed green inch worms removed from a non-chemically treated azalea plant.
The birds consumed 2-4 worms
apiece. Similar worms feeding on
other plants had been used before
with no ill effects. Without any treat ment attempts, signs started to abate
in approximately 90 minutes. Total
recovery was within 4 to 8 hours. ?

Mynah Bird Radiographs The normal trachea of the mynah
bird differs radiographically from the
psittacine. The lateral projection reveals an angulated ventral deviation in the trachea, just anterior to the thoracic inlet. The deviation is not
associated with the mynah's promi nent syrinx, and could be easily
misinterpreted as ventral displace ment from a soft tissue swelling or mass.

Wound Therapy In the June 15, 1987 issue of
J.A.V.M.A., a review article on
topical wound medications described the use of live yeast-cell derivative
(LYCD) ointment to stimulate ox
ygen consumption, epithelialization and collagen synthesis in wounds.
Human skin graft donor sites treated with LYCD ointment healed faster than sites treated with ointment base
only. Similar results were obtained in
dogs with open wounds.
Also known as skin respiratory fac
tor, LYCD is found in an over-the counter hemorrhoid preparation
(Preparation H). I have recently used
Preparation H on several wild birds
(and one alligator) with open wounds
