Abstract

The current study aimed to assess the effects of fat powder levels, oil levels, and two types of pellet binders, including bentonite and gum Tragacanth on the physical quality and pellet durability index (PDI) over 75 days. The experiment was conducted using a completely randomized design with a factorial arrangement. Experimental treatments included 5 to 10 kilograms of fat powder, 7 to 11 kilograms of oil, and pellet binders. The pellet binders consisted of bentonite, plant-based binders such as gum Tragacanth, and their combination. The present results indicated that using fat powder and oil levels, with pellet binders, significantly increased PDI in the starter period. The concentration and type of pellet binder were effective parameters in treatments during the experiment. Fat powder significantly improved the physical quality of the pellet on days 15, 30, 60, and 75, while oil notably improved the effects of the pellet on all days except day 0. Fat powder, oil, and pellet binder played crucial roles in determining the physical quality of pellets during the finisher period across all days. The interaction between fat powder and oil substantially affected finisher pellet quality on all days except days 15 and 45. Oil levels did not have impacts on the physical quality of the finisher pellets. Gum Tragacanth binder demonstrated the highest average physical pellet quality on days 0, 45, 60, and 75, while bentonite exhibited the best performance on days 15 and 30. The utilization of pellet binders combined with adding oil and fat powder to the diet, improve the physical qualities of the produced pellets. © 2026, The Author(s), Open Access: This article is licensed under a Creative Commons Attribution 4.0 International License, which permits use, sharing, adaptation, distribution and reproduction in any medium or format, as long as you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons licence, and indicate if changes were made.
