Popis: This study was conducted to evaluate glycine equivalent (Glyequi) requirement in low crude protein (CP) diets with different levels of standardised ileal digestible (SID) threonine (Thr) on performance, serum metabolites, and muscle creatine of broiler chickens from 1 to 21 d age. A total of 1275 one-day-old male Cobb-Vantress chicks were distributed in a completely randomised 3 × 5 factorial arrangement for a total of 15 treatments with 5 replicates of 17 birds each. Diets were formulated to comprise three dietary SID of Thr concentrations 6.9, 8.1 and 9.3 g/kg and five dietary Glyequi levels (12.8, 14.3, 15.8, 17.3 and 18.8 g/kg). An interaction (p
