Abstract

Commercial broilers are fed exclusively pelleted diets; this is due to research that has demonstrated numerous benefits to feeding pellets. The first objective was to investigate the effects of modest improvements in pellet quality on two modern broiler strains. Regardless of strain, feeding 80% pellets improved broiler performance from d 28 to 42. The second objective was to investigate the effects of feed form and liquid application method on feed augering segregation and subsequent broiler performance. In general, percent pellets steadily decreased across location throughout feed augering. Also, phytase segregation occurred throughout augering and was exacerbated in post-pellet liquid application diets. When the augered diets were fed to broilers, 75% pellets and post-pellet liquid application diets improved performance. The final objective was to investigate the change in percent pellets as feed was augered throughout an entire commercial poultry house. Ultimately, creating high-quality pellets decreases pellet attrition and improves broiler performance.
