As advancements in turkey genetics propel growth rates to unprecedented levels, the necessity for innovative nutritional strategies becomes increasingly apparent. Recent studies emphasize the significance of feed physical form—particularly pellet durability—as a pivotal factor influencing feed intake, final body weight, and overall profitability on turkey farms.
Understanding the Need for Optimization
In the past 40 years, genetic selection in commercial turkey breeds has led to a notable increase in their metabolic demands. Today, merely formulating precise diets is insufficient; optimizing the physical accessibility of nutrients is crucial. Research indicates that the physical form of feed (such as pellets compared to crumbs or mash) directly impacts the time turkeys spend feeding and the energy costs associated with consumption. When turkeys consume high amounts of fines, they expend extra maintenance energy, diverting calories that could otherwise support muscle growth.
The Challenge of Pellet Durability
Despite sophisticated milling technologies, the issue of pellet durability remains prevalent in the industry. Internal feed quality assessments reveal a concerning reality.

While a majority of the industry achieves high physical quality, the remaining minority of substandard feed represents a substantial economic loss.
Experimental Validation of Performance
To understand the financial implications of feed presentation, a controlled 112-day trial was executed using Aviagen Premium toms across six replicates (54 birds per group). This study compared three types of feed presentations—high PDI pellets, low PDI pellets, and a pure mash diet—while ensuring the nutritional specifications remained identical.
The study focused on key performance indicators including average daily gain (ADG), average daily feed intake (ADFI), and feed conversion ratio (FCR).
Data Analysis and Economic Outcomes
The findings revealed a stark difference based on feed form. The mash diet led to a severe 17% reduction in final body weight compared to high-quality pellets. Additionally, reducing pellet durability from a standard of 90% to just 81% (low PDI) resulted in decreased daily intake and subsequent drops in ADG. Although mash diets can marginally enhance litter dryness due to lower water intake, the negative impact on growth rates renders this option economically unfeasible.
Recommendations for Improvement
Investing in the pelleting process pays immediate dividends through improved zootechnical returns. Maintaining a Pellet Durability Index (PDI) of above 88% is essential for realizing the full genetic potential of modern toms. Prioritizing physical quality should never be sacrificed for milling efficiency.
Securing Economic Margins: The Aviance Approach
Feed mills often encounter variability in raw materials impacting pellet quality, even with stringent quality control measures. To minimize the risks tied to suboptimal PDI and safeguard breeder profit margins, it’s recommended to incorporate specialized feed additives.
A prominent solution is the integration of Aviance into turkey diets. This product is designed to improve nutrient absorption, balance intestinal flora, and enhance gut health overall. By optimizing intestinal mucosa absorptive capacity, Aviance maintains an optimal FCR and maximizes nutrient extraction, even amid challenges presented by subpar feed quality. Ultimately, this nutritional strategy lowers production costs, ensuring profitability, regardless of milling constraints.
