Special Issue Information

Dear Colleagues,

Meat quality has always been important to consumers, and it may be especially so in today’s world. Dietary nutrients are key factors that affect the meat quality in livestock and poultry. How do these nutrients regulate the meat quality, though, and what are the underlying mechanisms? To produce high-quality meat, it is necessary to understand the formation process of meat quality traits and the factors that control them. A greater understanding of the underlying mechanisms of nutritional regulation on meat quality will lead to novel strategies to improve livestock and poultry meat product quality.

Therefore, this Special Issue of Animals, entitled “The Regulation and Mechanism of Nutrition on the Formation of Meat Quality”, invites studies (original research papers or reviews) on the current state of knowledge of the subject. Specifically, this Special Issue should include, but is not limited to, the latest advances in the molecular mechanisms of dietary nutrients (nutrition level and diet composition, prebiotics and probiotics, gut microbiota, bioactive compounds, etc.) in regulating meat-quality-related traits, including lipid deposition, muscle biology, metabolism (lipid metabolism, glycometabolism, inflammation, immunologic function, etc).

We look forward to receiving your contributions.

Dr. Xinxia Wang
Guest Editor

This study analyzed the chemical composition and the β-carotene, tocopherol and retinol content of meat (musculus longissimus lumborum, musculus gluteus maximus) from young rams fed different silage-based diets. The animals were divided into four groups depending on the type of silage in the feed ration (hybrid ryegrass, Festulolium cv. Becva, Festulolium cv. Felopa, Festulolium cv. Paulita). The concentrations of the examined lipophilic compounds were measured via high-performance liquid chromatography (HPLC). Animals fed a diet based on ryegrass silage had the highest intakes of α-, β-, γ- and δ-tocopherol and total tocopherols (p < 0.01). Muscles of rams fed Festulolium silage-based diets contained more tocopherols (p < 0.01) and retinol (p < 0.01 in m. g. maximus; p = 0.053 in m. l. lumborum) than the meat of animals receiving hybrid ryegrass-based diets. The highest amounts of tocopherols (p < 0.01) and retinol (p < 0.01 in m. g. maximus; p = 0.053 in m. l. lumborum) were found in meat from rams fed rations based on silage made from Festulolium cvs. Felopa and Paulita. The analysis revealed a positive correlation between the intake of tocopherols and the α-tocopherol content of meat (r = 0.99), as well as between the β-carotene intake and the retinol content of meat (r = 0.92 in m. l. lumborum; r = 0.91 in m. g. maximus).
