This study evaluated nutrient utilisation and blood chemistry of Red Sokoto bucks fed a 10 and 20 % inclusion level of raw, water- and lime-soaked Hibiscus sabdariffa L. seeds in rice bran based diets. 21 Red Sokoto bucks aged 8–10 months and weighing 9–13 kg were randomly allotted into six treatments with three bucks each, while a seventh dietary treatment with zero inclusion of seeds served as control in a 2 × 3 factorial arrangement using a complete randomised design. The results indicated that increase in dietary inclusion levels of soaked H. sabdariffa seeds increased (P < 0.05) the nutrient utilisation of bucks as compared to the control, while a decrease was observed with increasing dietary inclusion levels of raw seeds. Dietary inclusion of both raw and water-soaked H. sabdariffa seeds increased (P < 0.05) the packed cell volume. Soaking also influenced the white blood cell value which increased with increasing inclusion levels of H. sabdariffa seeds. However, values of haemoglobin and red blood cells were only affected by 20 % inclusion of raw and water-soaked H. sabdariffa seeds (P < 0.05) compared to control. Inclusion of H. sabdariffa seeds furthermore reduced serum protein, albumin, globulin, glucose and urea levels compared to control. It is therefore concluded that H. sabdariffa seeds support haematopoiesis in Red Sokoto bucks. While both inclusion levels of water-soaked and 10 % raw H. sabdariffa seeds improved nutrient utilisation compared to control and 20 % inclusion of raw seeds, the 20 % inclusion of water-soaked H. sabdariffa seeds recorded the best nitrogen utilisation efficiency.
