Feed conversion ratio (FCR) increased linearly from 1.495 to 1.629 as dietary CP declined with a corresponding increase in distal jejunal starch-protein disappearance rate ratios from 2.08 to 3.17. These two parameters were quadratically related (r = 0.838; P < 0.001) and there was a linear relationship (r = 0.605; P < 0.001) between relative fat-pad weights and FCR. Increasing starch-protein disappearance rate ratios are detrimental for birds offered CP-reduced diets and the implications of these outcomes are discussed. | Publication Type: | Conference Publication | Conference Details: | Australian Poultry Science Symposium17-20/02/2019 | Source of Publication: | Proceedings of the Australian Poultry Science Symposium, v.30, p. 37-40 | Publisher: | University of Sydney | Place of Publication: | Sydney, Australia | ISSN: | 1034-6260 | Peer Reviewed: | Yes | HERDC Category Description: | E1 Refereed Scholarly Conference Publication | Other Links: | https://sydney.edu.au/vetscience/apss/ |
