The goal of the study was to ascertain the effect of feeding broiler chickens a diet containing annatto seed powder (Bixa orellana) and astaxanthin on their performance and health. The researchers used 225 sexed Ross-308 chickens that were only one day old The chickens were placed in one of 15 different cages, each of which contained one of five different treatments (for a total of 450 birds). There were three duplicates of each treatment, with a total of 15 birds in each replicate for a total of 45 birds in each replication. The following is how the research was conducted: The results showed a highly significant difference at the level of (p 0.01) for the treatments add T2, T3, T4, and T5 regarding final body weight average, with T1 serving as the control treatment and the standard diet not containing any additions. T2 including powdered annatto seeds at a rate of 0.5 grams per kilogram of feed, T3 including powdered annatto seeds at a rate of 1 gram per kilogram of feed, T4 including astaxanthin at At the level of significance (p0.05), Treatments T2, T3, and T5 performed significantly better than the control treatment T1 in terms of the growth in weight, the amount of feed consumed, and the total feed conversion factor.
