After 52 days of rearing, a blood sample was taken from the chickens to determine haematological, biochemical parameters and the concentration of the T₃ hormone. On the 56th day, 15 chickens from each batch were slaughtered. The presence of contact dermatitis was assessed by visual examination. The weights of the carcass and various organs were determined. The type of litter induced significant differences (p&lt;0.05) for contact dermatitis The incidence of foot pad dermatitis was 0%, 46.67%, 26.67% and that of kock burns was 0%, 6.67% and 0% respectively for Biochar group, Mixed group and Corn cobs group. Significant variations (p&lt;0.05) were recorded from the relative weights of the lungs. The number of white blood cells was higher (p&lt;0.05) in the mixed group while no difference was recorded for the neutrophil/lymphocyte ratio (p&gt;0.05). The biochemical and hormonal parameters were similar whatever the type of litter (p&gt;0.05). Biochar therefore improves the health status of broilers and does not harm their welfare. The evaluation of the physico-chemical and microbiological quality of the litters would be interesting for the understanding of the observed effects.</p> Vidjinnangni Fifamè Grâce Nadège Dedehou, Sourébou Hilaire Sanni Worogo, Boris Milognon Béhingan, Ibrahim Alkoiret Traoré , Sylvie Mawulé Hounzangbé-Adoté Copyright (c) 2022 Vidjinnangni Fifamè Grâce Nadège Dedehou, Sourébou Hilaire Sanni Worogo, Boris Milognon Béhingan, Ibrahim Alkoiret Traoré , Sylvie Mawulé Hounzangbé-Adoté https://creativecommons.org/licenses/by-nc-nd/4.0 http://sjournals.com/index.php/sjva/article/view/1736 Fri, 21 Oct 2022 00:00:00 +0000
