Special Issue Information

Dear Colleagues,

Nowadays, animal products are required to address many challenges: satisfying the global demand for animal protein, ensuring food security for the world population as well as contributing and maintaining to human health and animal welfare, and safeguarding the environment.

The quality of animal products is closely related to the quality of animal feeds; feeds and various feed additives have been shown to increase the nutritional quality of animal-origin food, which in turn promotes a healthy human diet. In addition, animal feeding contributes to the presence in animal products of a number of physiologically active components that deserve attention for their potential role in health promotion. In the future, feed formulation shall experience adaptations in order to contribute to more resource-efficient feed use, while meeting animal nutritional requirements, improving the health-promoting characteristics of food for humans, and assuring sustainable production systems.

In animal feed, a circular economy approach provides a cost-effective alternative to traditional, resource-intensive raw materials like corn and soybeans. The use of byproducts as animal feed helps create a more sustainable and resilient system by minimizing waste and maximizing the use of available resources.

We are placed to invite you to submit papers that address the use of feed additives, byproducts, or nutritional strategies for improving the quality of animal products and the environmental impact of animal productions.In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: effect of feed, additives/supplements, natural extract, enzymes, essential oils, plant metabolites, ammino acids, vitamins, yeast, probiotics, macroalgae and microalgae, and byproducts on the quality and functionality of animal products (milk and meat), as well as on the environmental impact of animal productions.

The objective of this exploratory study was to assess if microencapsulated arginine influences the physicochemical quality of beef. The study included three genetic groups: Angus, Hereford, and Angus × Hereford crossbreed. Two encapsulation systems were used with carnauba wax, at ratios of 3:1 and 2:1, carnauba wax:core (arginine), respectively. A control treatment was also included with no arginine addition. Encapsulated arginine with a 3:1 ratio increased redness by 19.66 at 28 d aged beef compared to the control and 2:1 ratio with values of 18.55 and 16.77, respectively (p = 0.01). Encapsulated arginine at a 3:1 ratio showed the lowest meat shear force values with 24.32 N at 28 d of ageing (p < 0.001). The Angus breed also had a low value of 24.02 N (p < 0.001). Finally, the highest values of intramuscular fat were observed with the inclusion of arginine in a 3:1 ratio. The fat value reached 2.12% with a 3:1 ratio (p = 0.002), while in the Angus breed it was 1.59%. The addition of carnauba wax-encapsulated arginine can improve meat quality. It enhances red color, tenderness, and marbling in bovine meat. Full article

The resource-intensive nature of the ruminant farming sector, which has been exacerbated by population growth and increasing pressure to reduce feed antibiotics and growth promoters, has sparked interest in looking for sustainable alternative feed sources to enhance ruminant production efficiency. Edible filamentous fungi, rich in macronutrients like proteins, offer promise in reducing the reliance on conventional protein sources and antimicrobials to improve feed quality and animal performance. The inclusion of single-cell proteins, particularly filamentous fungi, in ruminant feed has long been of scientific and industrial interest. This review focuses on the potential application of the extensively studied Aspergillus oryzae and its fermentation extracts in ruminant nutrition. It provides an overview of conventional ruminant feed ingredients, supplements, and efficiency. Additionally, this review analyzes the re-utilization of organic residues for A. oryzae cultivation and examines the effects of adding fungal extracts to ruminant feed on ruminal digestibility and animal performance, all within a circular bioeconomy framework.
