A critical issue emerged: riboflavin in conventional feed was prone to loss during storage and processing. As a result, riboflavin was incorporated as a functional additive into specialized feed formulations. Combined with microencapsulation technology to address its light sensitivity and oxidative instability, riboflavin is now precisely dosed according to the different growth stages of dairy cows. It has become a core nutrient for safeguarding cow health and high milk yield, driving the standardization and upgrading of livestock farming practices.&quot;]]],[&quot;p&quot;,{&quot;ind&quot;:{&quot;firstLine&quot;:32,&quot;firstLineChars&quot;:200},&quot;jc&quot;:&quot;justify&quot;,&quot;rPr&quot;:{&quot;fonts&quot;:{&quot;ascii&quot;:&quot;Times New Roman&quot;,&quot;cs&quot;:&quot;Times New Roman&quot;,&quot;eastAsia&quot;:&quot;\u5b8b\u4f53&quot;,&quot;hAnsi&quot;:&quot;Times New Roman&quot;,&quot;hint&quot;:&quot;default&quot;},&quot;sz&quot;:12,&quot;szUnit&quot;:&quot;pt&quot;},&quot;spacing&quot;:{&quot;line&quot;:1.5,&quot;lineRule&quot;:&quot;auto&quot;}},[&quot;span&quot;,{&quot;data-type&quot;:&quot;text&quot;},[&quot;span&quot;,{&quot;fonts&quot;:{&quot;ascii&quot;:&quot;Times New Roman&quot;,&quot;cs&quot;:&quot;Times New Roman&quot;,&quot;eastAsia&quot;:&quot;\u5b8b\u4f53&quot;,&quot;hAnsi&quot;:&quot;Times New Roman&quot;,&quot;hint&quot;:&quot;default&quot;},&quot;sz&quot;:12,&quot;szUnit&quot;:&quot;pt&quot;,&quot;data-type&quot;:&quot;leaf&quot;},&quot;The faint fluorescence observed in milk under ultraviolet light originates from riboflavin (vitamin B2) and its active derivatives present in the milk.

Both reactions require ATP as an energy source, and their efficiency is regulated by the dietary energy level and trace elements (e.g., zinc, which acts as an activator of flavokinase) in the cow\u2019s diet. The core regulatory feature of FMN and FAD lies in their reversible redox capacity: specifically, the oxidized forms of FMN\/FAD accept hydrogen atoms and are converted into their reduced forms, FMNH\u2082\/FADH\u2082; following electron transfer, these reduced forms revert to their oxidized states. This cyclic property allows them to continuously participate in redox reactions associated with protein metabolism, regulate the activity of key enzymes, and modulate microbial metabolic processes, thereby ensuring the efficient utilization and conversion of protein.&quot;]]],[&quot;p&quot;,{&quot;ind&quot;:{&quot;firstLine&quot;:32,&quot;firstLineChars&quot;:200},&quot;jc&quot;:&quot;justify&quot;,&quot;rPr&quot;:{&quot;fonts&quot;:{&quot;ascii&quot;:&quot;Times New Roman&quot;,&quot;cs&quot;:&quot;Times New Roman&quot;,&quot;eastAsia&quot;:&quot;\u5b8b\u4f53&quot;,&quot;hAnsi&quot;:&quot;Times New Roman&quot;,&quot;hint&quot;:&quot;default&quot;},&quot;sz&quot;:12,&quot;szUnit&quot;:&quot;pt&quot;},&quot;spacing&quot;:{&quot;line&quot;:1.5,&quot;lineRule&quot;:&quot;auto&quot;}},[&quot;span&quot;,{&quot;data-type&quot;:&quot;text&quot;},[&quot;span&quot;,{&quot;fonts&quot;:{&quot;ascii&quot;:&quot;Times New Roman&quot;,&quot;cs&quot;:&quot;Times New Roman&quot;,&quot;eastAsia&quot;:&quot;\u5b8b\u4f53&quot;,&quot;hAnsi&quot;:&quot;Times New Roman&quot;,&quot;hint&quot;:&quot;default&quot;},&quot;sz&quot;:12,&quot;szUnit&quot;:&quot;pt&quot;,&quot;data-type&quot;:&quot;leaf&quot;},&quot;Protein metabolism in dairy cows primarily consists of two core processes: ruminal microbial protein synthesis and host amino acid metabolism.

The synthesis of microbial protein is highly dependent on flavin coenzymes: FMN and FAD serve as prosthetic groups for various key microbial enzymes, including amino acid synthases and transaminases. They not only participate in the synthesis of basic amino acids such as alanine and glutamic acid but also promote the polymerization of amino acids to form peptides and proteins that can be absorbed and utilized by dairy cows. Supplementing riboflavin in the diet provides precursors for FMN and FAD synthesis, which significantly increases the population of dominant protein-synthesizing microbes in the rumen (e.g., Prevotella ruminicola and Amylovorax ruminantium). Simultaneously, it enhances the activity of flavin-dependent enzymes in these microbes, thereby improving the efficiency of microbial protein synthesis and reducing dietary nitrogen waste (evidenced by decreased ammonia nitrogen accumulation in the rumen).&quot;]]],[&quot;p&quot;,{&quot;ind&quot;:{&quot;firstLine&quot;:32,&quot;firstLineChars&quot;:200},&quot;jc&quot;:&quot;justify&quot;,&quot;rPr&quot;:{&quot;fonts&quot;:{&quot;ascii&quot;:&quot;Times New Roman&quot;,&quot;cs&quot;:&quot;Times New Roman&quot;,&quot;eastAsia&quot;:&quot;\u5b8b\u4f53&quot;,&quot;hAnsi&quot;:&quot;Times New Roman&quot;,&quot;hint&quot;:&quot;default&quot;},&quot;sz&quot;:12,&quot;szUnit&quot;:&quot;pt&quot;},&quot;spacing&quot;:{&quot;line&quot;:1.5,&quot;lineRule&quot;:&quot;auto&quot;}},[&quot;span&quot;,{&quot;data-type&quot;:&quot;text&quot;},[&quot;span&quot;,{&quot;fonts&quot;:{&quot;ascii&quot;:&quot;Times New Roman&quot;,&quot;cs&quot;:&quot;Times New Roman&quot;,&quot;eastAsia&quot;:&quot;\u5b8b\u4f53&quot;,&quot;hAnsi&quot;:&quot;Times New Roman&quot;,&quot;hint&quot;:&quot;default&quot;},&quot;sz&quot;:12,&quot;szUnit&quot;:&quot;pt&quot;,&quot;data-type&quot;:&quot;leaf&quot;},&quot;In the process of host amino acid metabolism, FAD plays a key role in the methionine cycle\u2014a critical pathway for amino acid metabolism and one-carbon unit transfer, which directly impacts the efficiency of milk protein synthesis. Specifically, FAD acts as a coenzyme for methylenetetrahydrofolate reductase (MTHFR), specifically catalyzing the conversion of 5,10-methylenetetrahydrofolate to 5-methyltetrahydrofolate. This reaction is the core step for the stable transfer of one-carbon units. 5-methyltetrahydrofolate then serves as a methyl donor, providing the essential methyl group required for the conversion of homocysteine to methionine. Methionine is a limiting essential amino acid for milk protein synthesis, and its availability directly affects the rate and yield of milk protein synthesis. Studies have shown that insufficient methionine supply can reduce milk protein production by 8%\u201312%. In addition, riboflavin and folic acid exhibit a significant synergistic effect: folic acid is responsible for carrying one-carbon units, while FAD derived from riboflavin ensures the activation and recycling of folic acid. Combined supplementation of both nutrients can increase the efficiency of the methionine cycle by more than 20%, further optimizing protein metabolism levels\u2014an effect that is particularly beneficial for promoting milk protein synthesis in high-yielding dairy cows.&quot;]]],[&quot;p&quot;,{&quot;ind&quot;:{&quot;firstLine&quot;:32,&quot;firstLineChars&quot;:200},&quot;jc&quot;:&quot;justify&quot;,&quot;rPr&quot;:{&quot;fonts&quot;:{&quot;ascii&quot;:&quot;Times New Roman&quot;,&quot;cs&quot;:&quot;Times New Roman&quot;,&quot;eastAsia&quot;:&quot;\u5b8b\u4f53&quot;,&quot;hAnsi&quot;:&quot;Times New Roman&quot;,&quot;hint&quot;:&quot;default&quot;},&quot;sz&quot;:12,&quot;szUnit&quot;:&quot;pt&quot;},&quot;spacing&quot;:{&quot;line&quot;:1.5,&quot;lineRule&quot;:&quot;auto&quot;}},[&quot;span&quot;,{&quot;data-type&quot;:&quot;text&quot;},[&quot;span&quot;,{&quot;fonts&quot;:{&quot;ascii&quot;:&quot;Times New Roman&quot;,&quot;cs&quot;:&quot;Times New Roman&quot;,&quot;eastAsia&quot;:&quot;\u5b8b\u4f53&quot;,&quot;hAnsi&quot;:&quot;Times New Roman&quot;,&quot;hint&quot;:&quot;default&quot;},&quot;sz&quot;:12,&quot;szUnit&quot;:&quot;pt&quot;,&quot;data-type&quot;:&quot;leaf&quot;},&quot;In summary, FMN and FAD, the derivatives of riboflavin, act as key regulators of protein metabolism in dairy cows by modulating ruminal microbial protein synthesis and the host methionine cycle.

This cyclic property allows them to continuously participate in redox reactions associated with protein metabolism, regulate the activity of key enzymes, and modulate microbial metabolic processes, thereby ensuring the efficient utilization and conversion of protein.&quot;]]],[&quot;p&quot;,{&quot;ind&quot;:{&quot;firstLine&quot;:32,&quot;firstLineChars&quot;:200},&quot;jc&quot;:&quot;justify&quot;,&quot;rPr&quot;:{&quot;fonts&quot;:{&quot;ascii&quot;:&quot;Times New Roman&quot;,&quot;cs&quot;:&quot;Times New Roman&quot;,&quot;eastAsia&quot;:&quot;\u5b8b\u4f53&quot;,&quot;hAnsi&quot;:&quot;Times New Roman&quot;,&quot;hint&quot;:&quot;default&quot;},&quot;sz&quot;:12,&quot;szUnit&quot;:&quot;pt&quot;},&quot;spacing&quot;:{&quot;line&quot;:1.5,&quot;lineRule&quot;:&quot;auto&quot;}},[&quot;span&quot;,{&quot;data-type&quot;:&quot;text&quot;},[&quot;span&quot;,{&quot;fonts&quot;:{&quot;ascii&quot;:&quot;Times New Roman&quot;,&quot;cs&quot;:&quot;Times New Roman&quot;,&quot;eastAsia&quot;:&quot;\u5b8b\u4f53&quot;,&quot;hAnsi&quot;:&quot;Times New Roman&quot;,&quot;hint&quot;:&quot;default&quot;},&quot;sz&quot;:12,&quot;szUnit&quot;:&quot;pt&quot;,&quot;data-type&quot;:&quot;leaf&quot;},&quot;Protein metabolism in dairy cows primarily consists of two core processes: ruminal microbial protein synthesis and host amino acid metabolism.

The synthesis of microbial protein is highly dependent on flavin coenzymes: FMN and FAD serve as prosthetic groups for various key microbial enzymes, including amino acid synthases and transaminases. They not only participate in the synthesis of basic amino acids such as alanine and glutamic acid but also promote the polymerization of amino acids to form peptides and proteins that can be absorbed and utilized by dairy cows. Supplementing riboflavin in the diet provides precursors for FMN and FAD synthesis, which significantly increases the population of dominant protein-synthesizing microbes in the rumen (e.g., Prevotella ruminicola and Amylovorax ruminantium). Simultaneously, it enhances the activity of flavin-dependent enzymes in these microbes, thereby improving the efficiency of microbial protein synthesis and reducing dietary nitrogen waste (evidenced by decreased ammonia nitrogen accumulation in the rumen).&quot;]]],[&quot;p&quot;,{&quot;ind&quot;:{&quot;firstLine&quot;:32,&quot;firstLineChars&quot;:200},&quot;jc&quot;:&quot;justify&quot;,&quot;rPr&quot;:{&quot;fonts&quot;:{&quot;ascii&quot;:&quot;Times New Roman&quot;,&quot;cs&quot;:&quot;Times New Roman&quot;,&quot;eastAsia&quot;:&quot;\u5b8b\u4f53&quot;,&quot;hAnsi&quot;:&quot;Times New Roman&quot;,&quot;hint&quot;:&quot;default&quot;},&quot;sz&quot;:12,&quot;szUnit&quot;:&quot;pt&quot;},&quot;spacing&quot;:{&quot;line&quot;:1.5,&quot;lineRule&quot;:&quot;auto&quot;}},[&quot;span&quot;,{&quot;data-type&quot;:&quot;text&quot;},[&quot;span&quot;,{&quot;fonts&quot;:{&quot;ascii&quot;:&quot;Times New Roman&quot;,&quot;cs&quot;:&quot;Times New Roman&quot;,&quot;eastAsia&quot;:&quot;\u5b8b\u4f53&quot;,&quot;hAnsi&quot;:&quot;Times New Roman&quot;,&quot;hint&quot;:&quot;default&quot;},&quot;sz&quot;:12,&quot;szUnit&quot;:&quot;pt&quot;,&quot;data-type&quot;:&quot;leaf&quot;},&quot;In the process of host amino acid metabolism, FAD plays a key role in the methionine cycle\u2014a critical pathway for amino acid metabolism and one-carbon unit transfer, which directly impacts the efficiency of milk protein synthesis. Specifically, FAD acts as a coenzyme for methylenetetrahydrofolate reductase (MTHFR), specifically catalyzing the conversion of 5,10-methylenetetrahydrofolate to 5-methyltetrahydrofolate. This reaction is the core step for the stable transfer of one-carbon units. 5-methyltetrahydrofolate then serves as a methyl donor, providing the essential methyl group required for the conversion of homocysteine to methionine. Methionine is a limiting essential amino acid for milk protein synthesis, and its availability directly affects the rate and yield of milk protein synthesis. Studies have shown that insufficient methionine supply can reduce milk protein production by 8%\u201312%. In addition, riboflavin and folic acid exhibit a significant synergistic effect: folic acid is responsible for carrying one-carbon units, while FAD derived from riboflavin ensures the activation and recycling of folic acid. Combined supplementation of both nutrients can increase the efficiency of the methionine cycle by more than 20%, further optimizing protein metabolism levels\u2014an effect that is particularly beneficial for promoting milk protein synthesis in high-yielding dairy cows.&quot;]]],[&quot;p&quot;,{&quot;ind&quot;:{&quot;firstLine&quot;:32,&quot;firstLineChars&quot;:200},&quot;jc&quot;:&quot;justify&quot;,&quot;rPr&quot;:{&quot;fonts&quot;:{&quot;ascii&quot;:&quot;Times New Roman&quot;,&quot;cs&quot;:&quot;Times New Roman&quot;,&quot;eastAsia&quot;:&quot;\u5b8b\u4f53&quot;,&quot;hAnsi&quot;:&quot;Times New Roman&quot;,&quot;hint&quot;:&quot;default&quot;},&quot;sz&quot;:12,&quot;szUnit&quot;:&quot;pt&quot;},&quot;spacing&quot;:{&quot;line&quot;:1.5,&quot;lineRule&quot;:&quot;auto&quot;}},[&quot;span&quot;,{&quot;data-type&quot;:&quot;text&quot;},[&quot;span&quot;,{&quot;fonts&quot;:{&quot;ascii&quot;:&quot;Times New Roman&quot;,&quot;cs&quot;:&quot;Times New Roman&quot;,&quot;eastAsia&quot;:&quot;\u5b8b\u4f53&quot;,&quot;hAnsi&quot;:&quot;Times New Roman&quot;,&quot;hint&quot;:&quot;default&quot;},&quot;sz&quot;:12,&quot;szUnit&quot;:&quot;pt&quot;,&quot;data-type&quot;:&quot;leaf&quot;},&quot;In summary, FMN and FAD, the derivatives of riboflavin, act as key regulators of protein metabolism in dairy cows by modulating ruminal microbial protein synthesis and the host methionine cycle.
