ISSUE FOCUS 28 FEED & ADDITIVE MAGAZINE June 2022 gram of egg generated was improved by 4.6 points and FCR based on a dozen eggs was better by 3.3 points. Average daily feed intake tended to be similar regardless of diet across the length of the trial but was improved for birds receiving IntelliBond trace minerals in the first 6 weeks. Looking at egg-based results, birds receiving the IntelliBond -based supplementation generated eggs with better albumen percentage and that had lower shell reflectivity, but most egg quality parameters were similar for birds on both diets. The type of dietary trace mineral provided did generate a reaction based on the heat stress conditions. Laying hens getting the feed supplemented with IntelliBond-based trace minerals did not have the same response to high-heat conditions. Instead, the supplementation appeared to mitigate the drop in egg production during periods of heat stress. References 1. United Nations.
