This peer-reviewed study examined dietary xylanase and protease supplementation in broilers, finding significant improvements in feed conversion ratio (FCR) and European production efficiency factor (EPEF) across enzyme groups compared to controls. Protease showed main effects on FCR during key periods and interacted with xylanase for enhanced outcomes. Additional benefits included modulated cecal fermentation and improved tibiotarsus bone metrics.

UC Davis researchers at Digestiva are developing specialized protease enzymes added to foods to enhance protein digestibility without altering taste or texture. Activated in the stomach, these proteases target specific proteins to reduce indigestion, bloating, and support health benefits like blood glucose modulation and inflammation reduction. The technology aims to improve protein nutrition in the US and developing countries by maximizing suboptimal protein sources.

This review of recent clinical studies highlights protease enzymes' role in enhancing protein digestion, reducing food intolerance symptoms like those from gluten and casein via DPP IV activity, and lowering gastric digesta viscosity by 2.75-fold in vitro. Fungal-derived proteases excel in acidic conditions, minimizing undigested protein fragments linked to discomfort. Evidence supports digestive enzyme blends, including proteases, for gut health and nutrient absorption in US health trends.
