Microbial phytase improves performance and bone traits in broilers fed diets based on soybean meal and containing lupin meal

摘要: A completely randomised design study with a 3 × 2 factorial arrangement was conducted. total of 480 male broiler chickens were used to determine the influence phytase addition, plant protein source [soybean meal, soybean meal + 200 g/kg blue lupin (Lupinus angustifolius L.) or yellow luteus L.)] on performance chickens, ileal calcium (Ca), phosphorus (P) and digestibility, tibia bone characteristics nitrogen-corrected apparent metabolisable energy. All diets deficient in Ca, available P as well lysine sulfur amino acids. Birds fed different sources characterised by similar bodyweight gain feed intake during whole trial but conversion ratio higher when birds supplemented (P 0.05), whereas content lower < 0.05). highest phytase-supplemented Ca irrespective source.
