Application of vitreous Maize Endosperm in poultry feeding on the production results, chemical composition of meat and skin and meat colour in meat chicken

Abstract

Corn starch is the most important food ingredient, but also the main energy source for poultry. In corn grain 98% of starch comes from endosperm. The aim of this study was to determine the impact of vitreous (resistant) maize starch in broilers feeding on: basic product indicators, chemical composition of meat, and skin and meat colour. The study was conducted by a single-factor experiment with a total of four dietary treatments on the Ross 308 heavy hybrid broiler chickens, on 480 chickens overall, divided into four groups, three experimental and one control. The chickens of the control group were fed with 100% corncobs, while the experimental groups had the share of corncobots replaced by fractions of vitreous maize starch in the ratio of 25%, 50% and 75%. In this study, a positive effect on chickens for experimental treatment was related to the follow- ing factors: daily intake (at the end of the experiment), increased food consumption over four weeks, food conversion in the first part of the experiment, the value of b* index of skin and white meat.
