The rising cost and limited availability of conventional feed have driven the search for sustainable and economical alternatives. Sorghum grain (Sorghum bicolour), with a nutritive value comparable to maize, is considered a suitable substitute in poultry diets. This study evaluated the effects of sorghum grain inclusion in duck pellets on feed intake, growth performance, and blood profile. Thirty unsexed ducks, approximately 21 days old, were assigned to two groups: one fed sorghum-based pellets (treatment) and the other fed commercial pellets (control). Over six weeks, feed intake, growth, and blood parameters were assessed. Ducks fed the sorghum-enriched pellets showed significantly (p<0.05) better growth, with higher body weight (1298.0 vs. 953.3 g/bird) and daily weight gain (30.9 vs. 22.7 g/day/bird). They also had a lower, though not significant (p>0.05), feed conversion ratio (4.9 vs. 6.9). Blood biochemistry indicated higher haemoglobin (11.2 vs. 10.37 g/dL), red blood cell counts (2.3 vs. 2.2×10¹²/L), mean corpuscular haemoglobin (49.7 vs. 49.3 pg), and white blood cell counts (111.4 vs. 69.1×10⁹/L) in the treatment group, though differences were not significant (p>0.05). In conclusion, incorporating sorghum grain into duck pellets improves growth performance and positively influences blood profiles.
