ABSTRACT
The aim of this study was to assess the influence of age of whole sorghum grain introduction on productivity of male broiler chickens. In total, 324 one-day-old broiler chickens were assigned in a completely randomized design to 3 treatments (age of introduction of whole sorghum grain: 0, 11 and 25 days) with 9 replicates in each. Animals were offered 50% pre-pelleted whole sorghum at different growing ages. Body weight and feed intake were measured on a pen basis at 10, 25 and 35 day of age, and feed conversion ratio (FCR) was calculated. Birds introduced to whole sorghum grain feeding from day 0 and from 25 day of age, at 35 day of age were heavier and had better FCR (P < 0.05) than those to which whole grain was introduced from day 11. The relative visceral organ weights, meat parts yield, meat colour and pH were not influenced (P > 0.05) by the age of introduction of whole sorghum. The digestibility of gross energy, crude protein and starch were also not affected (P < 0.05). The age of introduction influenced certain performance parameters in broiler chickens. So, early feeding whole grain (at post-hatch) marginally improved body weight and FCR in broiler chickens.
