“…Different solutions have been used in order to improve PPQ. The first solution is the liquid addition technique, in which a liquid such as water can be evenly sprayed into a mixer (Moritz et al, 2003; Hott et al, 2008). Water spray into a mixer at the specific dosage is considered as the first solution for improving PPQ which is the cheapest method to enhance PDI, but it may increase the risk of mixer contamination and wet mixing time during the feed manufacturing.…”

Two experiments were conducted to evaluate the effects of different types and levels of mixer-added fat (soybean oil: SO and calcium fat powder: CFP) and pellet binders (PBs: calcium lignosulfonate (CaLS) and bentonite (Ben)) on physical pellet quality (PPQ) parameters. PPQ included pellet durability index (PDI), pellet hardness, and pellet length of broiler diets processed under short-term conditioning. The first experiment had 4 treatments arranged as a 2 × 2 factorial with 2 types (SO and CFP) and 2 levels (1.5 and 3%) of mixer-added fat. In the second experiment, 22 treatments, combinations of 2 types of mixer-added fat (SO and CFP) at 3 levels (0, 1.5 and 3%) and 2 types of PB (CaLS = 0, 0.5, and 1% and Ben = 0, 1, and 2%), were arranged by a completely randomized design. PDI was measured by 2 devices: Pfost Tumbling box (PDIT) and Holmen NHP tester (PDIH). The results showed that the diets containing 1.5% CFP without PB had significant differences in all PPQ parameters. The results revealed that adding 0.5% CaLS to the 3% SO diets significantly enhanced PDIH, pellet hardness, and pellet length compared to other treatments. Moreover, 1.5% CFP diets with 2% Ben had significantly higher PDIT, PDIH, and pellet hardness among the treatments. Based on contour plots, different levels of Ben in the diets containing SO failed to create optimum PDIT values (>96%). However, 1.5 to 2.50% CFP diets without Ben had the optimum PDIT values. The optimum PDIT value was achieved by the diets containing 3% SO in the range of 0.21 to 0.56% CaLS. Furthermore, adding 0.5% CaLS to the diets containing less than 2.86% SO resulted in suboptimal PDIT values (<96%). The diets containing 1.5 to 2.50% CFP without CaLS had the optimum PDIT values. However, increasing CaLS levels more than 0.38% led to suboptimal PDIT values. Overall, these results indicated that the selection of appropriate PBs should be based on type and level of mixer-added fat.

“…This was later supported by Moritz et al (2002 and2003) and may be an effective method of optimizing pellet durability and efficiency of the pelleting process. Likewise, increased pellet durability has been reported as a result of low moisture/mold inhibitor inclusion at the mixer in commercial mills (Hott, 2007). Skoch et al (1983a;1983b) reported increased pellet durability as well as decreased damage to starch as a result of steam conditioning poultry diets.…”

Loop, and Laurel Shires, for their time and assistance in the feed mill. I must also express my thankfulness to Tammy Webster and Sarah Beamer for their cooperation and assistance. A sincere thank you also goes out to the West Virginia University Animal and Nutritional Sciences office support staff for the seemingly endless amount of assistance that you have provided throughout the past few years. I would also like to thank Mrs. Jo Gulley, as well as the entire Division of Animal Feeds at the U.S. Food and Drug Administration's Center for Veterinary Medicine for giving me the opportunity to begin a career while subsequently completing my degree. I would like to express my deepest gratitude to my family; my parents, John and Carolyn Smith, my siblings, Kimberly Huffman and Ethan Smith, and my grandparents, Hazel and Bill McAmis, and Margaret and Dean Smith, for their endless support, patience, and encouragement.
