Methionine, as the first limiting amino acid in feed additives, is of great importance to farmers. Currently, the global economic stagnation and rising prices of some raw materials have led to a shortage of methionine, causing its price to rise. This is especially true for large-scale, standardized farms, where the demand for methionine is even higher. To avoid waste and efficiently utilize feed-grade methionine, it is essential to choose higher-quality methionine suppliers. This article will focus on the scientific use of methionine in feed, its differentiated value, market functions, and future development trends, ensuring everyone understands the scientific application and market value of methionine in feed. - Polifar

Beta-carotene is a natural orange-yellow pigment that serves as both a coloring agent and a nutritional fortifier in food. This article, based on China GB 2760-2024, systematically introduces its basic properties, regulations, standards, physiological functions, and industrial applications. Beta-carotene is a fat-soluble powder, primarily prepared through synthesis, fermentation, and natural extraction. It is a precursor to vitamin A and possesses antioxidant and immune-enhancing properties. This substance can be used for coloring and nutritional fortification in various foods, including beverages, baked goods, and dairy products. With continuous innovation in related formulation technologies, beta-carotene is evolving from a traditional coloring agent to a nutritional and health-oriented product, showing broad application prospects. - Polifar

Zinc sulfate monohydrate, with its high zinc content (≥35.5%), high water solubility, and 100% bioavailability (reference standard), has become the preferred zinc supplement for livestock, poultry, and aquaculture. It participates in the activity of over 300 enzymes, promoting growth, strengthening immunity, protecting coat and fur, and improving reproductive performance. It also possesses astringent and bactericidal effects, controlling various livestock diseases, and its potency (zinc oxide is only 50%~80% of zinc sulfate) is superior. Precise addition can correct zinc deficiency, optimize the metabolism of low-protein diets, and achieve increased farming efficiency and cost control. - Polifar
