An investigation was conducted
on 540 scavenging chickens of two age groups (below 6 month and above
6 month) taking equal number from each of 6 upzilas (sub-district) under
4 districts in 3 seasons (Summer, Winter and Rainy season). The birds
were collected from farmer`s house between 4:0 and 5:0 pm. Collected
birds were slaughtered and dissected to collect different parasites
from suspected organs. Crop and gizzard contents (CGC) were collected
for nutritional analyses. CGC was processed and analyzed for proximate
components, calcium (Ca) and phosphorous (P). The CGC contained 2678
Kcal/kg DM TME, 11.72% CP, 0.41% Ca and 0.34% P. Seasonal variation
had significant effect on TME availability but not on CP content. Seasons,
areas and their interactions had significant effect on Ca availability.
Availability of Ca and P to younger birds was fewer than that of to
aged birds, but reverse result was found for TME. It was concluded that
all scavenging birds were under deficient nutritional status.
