We report a preliminary study on the effect of grower feed diet supplemented with mashed
Ganoderma lucidum
against some enteric zoonotic parasites of wild rock pigeons (
Columba livia
) in Benin City, Nigeria. The pigeons were fed
ad libitum
with supplemented and non-supplemented grower feed diet in sawdust-floored squared wooden cages (45 cm x 30 cm x 20 cm) at room temperature for 21 days. They were sacrificed at days 14 and 21 for profiling of their zoonotic enteric parasites. High prevalence (77.7%) of Cestodes (tapeworms) and low prevalence (12.3%) of nematodes were recorded in the control pigeon fed non-supplemented grower feed compared to those on diet supplemented with
Ganoderma. Cestodes (Helminths) such as
Hymenolepsis carioca
,
Amoebataenia cuneata
,
Raillietina tetragona
,
Raillietina serrata
,
Inermicapsifer spp.
,
Hymenolepsis spp.
, and a species of nematode (
Ascaridia columbae
) were identified in the gastrointestinal tract of the experimental pigeons. A few species (< 8 %) of Trematodes yet to be fully identified were also observed. The low population of helminth parasites and overall weight decrease of pigeon fed with diet supplemented with
Ganderma lucidum recorded during the study suggest improved removal of digestive microbes, intestinal health, and gastrointestinal motility. These findings were aimed at contributing to the already existing knowledge on the use of feed additives, probiotics and supplementations in poultry farming.
