摘要: Three experiments were conducted to evaluate the applicability of Taguchi method (TM) and optimisation algorithms optimise branch chain amino acids (BCAA) requirements in 0 7 d broiler chicks. In first experiment, standardised digestible (SID) apparent metabolisable energy (AME) values maize, wheat soya bean meal evaluated. second three factors including leucine (Leu), isoleucine (Ile) valine (Val), each at 4 levels, selected, an orthogonal array layout L16 (4(3)) using TM was performed. After data collection, average daily gain (ADG) feed conversion ratio (FCR) obtained TM. The multiobjective genetic algorithm (MOGA) random search (RSA) also applied predict optimal combination BCAA for performance. third a growth study optimum by TM, MOGA RSA, results compared with those birds fed diet formulated according Ross 308 recommendations. resulted 13.45 g/kg SID Leu, 8.5 g/kg Ile 10.45 g/kg Val as level maximum ADG (21.57 g/bird/d) minimum FCR (1.11 g feed/g gain) 0- 7-d-old chickens. predicted following combinations: Leu = 14.8, Ile = 9.1 Val = 10.3 (22.05) (1.11). RSA Leu = 16.0, Ile = 9.5 Val = 10.2 (22.67), Leu = 15.5, Ile = 9.0 Val = 10.4 achieve (1.08). validation experiment confirmed that yielded determination dietary acid improved Aviagen However, based on live animal trial, overpredicted requirement general, these studies showed may be used nutrient poultry.
