Abstract

An experiment was conducted to evaluate the effect of three levels of supplemental threonine on the performance, carcass characteristics and blood parameters of broiler chickens. It was hypothesised that supplemental threonine would improve overall broiler chicken performance. One hundred and sixty day-old arbor acres broiler chicks were randomly allotted to 4 treatments. Each treatment was replicated 4 times and each replicate had 10 birds. The treatments were treatment 1 (control treatment): no supplemental threonine, treatment 2: 250 mg supplemental threonine, treatment 3: 500 mg supplemental threonine and treatment 4: 750 mg supplemental threonine. The experiment lasted 56 days. Birds on treatment 3 had significantly (p < 0.05) higher live weight than birds on the other treatments. No significant differences were observed in the weight gain, feed intake and feed conversion ratio of the birds on the different treatments. Platelet, white blood cell, red blood cell, heterophil counts and globulin values all differed significantly among birds on all the treatments. The results showed that supplemental threonine (500 mg) has the potential to enhance growth performance and blood health of broiler chickens.
