The aim of this study was to compare the histomorphometry of the skin in Fulani ecotypes/local and broiler chickens. A purposive sampling method was used to select ten (10) healthy local and broiler chickens each which were purchased from the meat market of Sokoto metropolis. The birds were weighed and sacrificed by severing the jugular veins. The feathers around the abdomen, neck, pectoral, synsacral and thigh were plucked and skin samples collected from same areas and processed using routine Hematoxylin and Eosin procedures. The epidermal skin thickness of the abdominal, neck and pectoral segments in broilers were significantly thicker (P≤0.05) compared to that of the local chickens. However, the thigh skin in local chicken was significantly thicker (P≤0.05) than in the broilers and the synsacral skin segment showed no significant difference between the two birds. Furthermore, the abdominal skin epidermal thickness has the highest mean thickness in both birds and the lowest epidermal skin thickness was seen in the thigh and neck regions in broiler and local chickens respectively. The loosely arranged fewer number of cells observed in the hypodermis create spaces which connect with air sacs to enhance their flying abilities. It was concluded that broilers have thicker skin compared to the Fulani ecotypes (local chicken) and this difference in the epidermal thickness observed between the two breeds could be related to the difference in their genetic composition, feeding, environmental condition and age. Furthermore, a thicker epidermis signifies a better physical barrier, chemical barrier and immunologically active barrier and also a better water holding capacity of the skin in broilers than in the Fulani Ecotypes.
