We spoke to Frances Yan, senior research scientist in poultry nutrition, Novus International, at IPPE last week to hear more about research she had presented at the Georgia event related to the use of blended essential oils and organic acids in broilers facing a disease challenge, in a feeding trial.
Abstract A battery study was conducted to evaluate the efficacy of phytase superdosing in improving growth performance, pancreatic response, and nutrient digestibility of broilers with a high trypsin inhibitor model. There were 5 dietary treatments: positive control (PC), negative control 1 (NC1), NC1+ 1500 U/kg phytase, negative control 2 (NC2), and NC2 + 1500 U/kg phytase.
