Upregulated Proventricular Pepsinogens and Improved Feed Efficiency in Broilers by the Combination of Supplemented Sugarcane Bagasse and Coarsely Ground Corn in Pelleted Diets

Abstract

<p>Measures to improve bird performance have been sought due to the imminent phase out of infeed antibiotics in poultry and continued demand for higher poultry feeding efficiency. Promotion of gizzard development by physical structure of feed ingredients or addition of dietary fibre is one such strategy with the hypothesis that larger ingredient particles and higher fibre enhance digestive enzyme secretion and feed efficiency in broilers (Kheravii etal., 2017" and Svihus, 2011).</p>
