SPECIAL STORY FEED & ADDITIVE MAGAZINE February 2023 55 of the ingredients may require greater care during storage. The smaller the particle size and the denser the ingredient, the lower the aeration rate and the greater the possibility of this ingredient accumulating in corners in storage rooms. The higher the moisture content, the greater the possibility of proliferation of undesirable microorganisms (bacteria and fungi). If the saturated fat content in oils and fats is on the high side, they may require heating for fluidity in the dosing system. But constant heating can increase fat oxidation rates. All these factors need to be monitored and adjusted in feed mill operations. 9. Operational characteristics in the feed mill: When using alternative raw materials, it is necessary to have a structure in the feed mill that allows the receipt, storage and dosage of these items. With this, structural adaptations (more storage silos, more dosing silos, liquid dosing systems) are necessary so that the new ingredients can be used. 10. Inclusion level at different ages: The general recommendations are to avoid the use of alternative ingredients in very young chickens (less than 5 weeks of age) because the gastrointestinal system of chickens at this stage is in the process of development and possible problems at this stage can generate consequences during the weeks that follow. For laying hens in production, the use should aim for the maximum recommended dosage. It is recommended to carefully monitor the performance of the flock, especially as hens get older. 11. Ingredient particle size: A chicken has greater difficulty in grasping very fine and/or extremely coarse feed particles (such as whole corn kernels). Therefore, the physical presentation of the ingredients should be taken into consideration. For example, millet can be offered whole to chickens, while sorghum requires grinding (like corn) but allowing a percentage of whole grains (around 20% of the volume used) to be present in the feed.
