scavenging indigenous chickens were bought from different
smallholder farms and villages in Embu and Mbeere districts. Of these, 77 were ad
ult
chickens, 21 grower birds and 7 chicks. On examination, 26/105 (24.76%) birds had female
Tetrameres
species of worms in their proventriculi. A total of 7/77 (9.1%) adult chickens,
14/21 (66.7%) grower birds and 5/7 (71.43%) chicks were infected by the
parasites. The
number of parasites per proventriculus ranged from 2
–
15 in adult chickens, 1
–
47 in
grower birds and 5
–
71 in chicks. Both male and female parasites were recorded. Most
proventriculi had one to thirty parasites but grower birds and chic
ks had heavy infe
stations
as compared to adult chickens. Grossly, black spots representing the red globular female
worms were observed spread out over the thickened walls of the proventriculi while male
worms were identified using a microscope. There was e
xcess mucous exudation in the
affected proventriculus and some had blood stained exudates. Proventricular glands had
variable degree of destruction depending on the infestation. The results show heavy
Tetrameres
species infestation in young birds than in
adults that may contribute to the high
mortality rates observed in these ages due to thickened walls and blockage of proventriculi,
amaciation and anaemia. These parasites require to be controlled in these birds | en |
