Feed Additives Supplier for Animal Nutrition & Feed Manufacturing

Amino Acids

DL-Methionine, L-Lysine, L-Threonine, and L-Valine are the core essential amino acids used to balance feed protein profiles, particularly in poultry and swine diets where cereal-based feeds are naturally deficient in these amino acids. Supplementing with crystalline amino acids allows formulators to reduce overall crude protein levels while still meeting an animal’s amino acid requirements, improving feed efficiency and reducing nitrogen excretion. As a feed additives supplier, Terracore also stocks Arginine, L-Glutamine, Glycine, and Tryptophan for specialised nutrition programs, plus L-Citrulline and Taurine, which are increasingly used in pet food and aquaculture formulations for their roles in circulatory and cardiac health.

Vitamins & Premixes

Vitamin premixes combine multiple fat- and water-soluble vitamins into a single, pre-blended product for consistent inclusion in feed formulations, while individual vitamins allow formulators to fine-tune a premix to specific species or production stage requirements. As a feed additives supplier stocking the full vitamin range, Terracore supplies Vitamin A Acetate, the complete B-vitamin family (B1 Thiamine, B2, B3 as both Nicotinamide and Nicotinic Acid, B5 Pantothenic Acid, B6, B9 Folic Acid, and B12 Cobalamin), Biotin, Vitamin D3, Vitamin E Acetate, and Vitamin K2 and K3 — covering everything a premix producer needs from a single source rather than sourcing individual vitamins from multiple suppliers.

Protein Sources

Dairy, pea, potato, and soy protein provide concentrated, digestible protein for young animal diets and specialty feed applications, each with a different amino acid profile and allergen consideration. Collagen Peptide is used in more specialised nutrition applications, including pet food and functional feed products. Casein, Gelatin, and Gluten (Wheat) round out this group as additional protein and binding sources, with Gelatin also functioning as a capsule and coating material in some feed applications.

Fibre Sources

Potato fibre, soluble fibre, and other fibre sources support digestive health and gut function, and are increasingly used in monogastric diets to manage digestive transit and support beneficial gut microflora. Gum Arabic, Konjac Gum, Tara Gum, Pectin, and Microcrystalline Cellulose (MCC) add further texture, binding, and fibre functionality, particularly in pelleted and extruded feed products where a feed additives supplier’s fibre range needs to support both nutrition and processing quality.

Acidifiers & Preservatives

Citric Acid, Fumaric Acid, Malic Acid, Propionic Acid, and Lactic Acid & Lactates are organic acids used to lower feed and gut pH, supporting digestion and inhibiting pathogenic bacteria, particularly important in young animal diets as an alternative to antibiotic growth promoters.

Potassium Sorbate, Sorbic Acid, Acetates, Sodium Acetate, Sodium Diacetate, Benzoate, and Benzoic Acid function primarily as preservatives, extending feed shelf life by inhibiting mould and yeast growth. Antioxidant preservatives including BHA, BHT, TBHQ, Propyl Gallate, Erythorbic Acid, and Sodium Erythorbate protect fats and oils in feed from oxidative rancidity, while Ascorbic Acid (Vitamin C), Glucono Delta Lactone, and Tartaric Acid round out this group. This is our largest sub-category, reflecting how central acidification and preservation are to any serious feed additives supplier’s range.

Minerals & Salts

Salt, Sodium Bicarbonate, and Sodium Sulphate provide essential electrolytes and buffering capacity, with Sodium Bicarbonate commonly used to buffer rumen pH in dairy cattle diets. Feed Phosphates (MCP, DCP), Dipotassium Phosphate, Sodium Aluminium Phosphate, Tricalcium Phosphate, and Tripotassium Phosphate supply digestible phosphorus and calcium, essential for bone development and metabolic function. Calcium Citrate, Trisodium Citrate, and Gluconic Acid serve as calcium and chelating sources, while Cobalt Sulfate, Zinc Citrate, Iodine, Potassium Iodate, and Potassium Iodide cover the trace mineral requirements most animal nutrition programs need alongside their main mineral premix.

Functional & Nutritional Additives

Betaine and Choline Chloride both function as methyl donors and support liver and fat metabolism, with Betaine also providing osmoregulatory benefits under heat stress. Glycerin, Glycols (MPG USP), MCT Oils, and Dextrose Monohydrate serve as energy sources and carriers, particularly valuable in young animal diets and liquid feed applications. Hydrocolloids (CMC), Mono-diglycerides & Ester Compounds, Lecithin, and Propylene Glycol Alginate function as binders, emulsifiers, and pellet-quality enhancers in feed manufacturing.

Astaxanthin, Betacarotene, and Canthaxanthin are pigment additives widely used in aquaculture and poultry diets to enhance flesh and yolk colour. Sodium Gluconate, Maltodextrin, Sodium Alginate, Sodium Ascorbate, Sorbitol, Triacetin, Glyceryl Triacetin, L-Carnitine Tartrate, Linolenic Acid, and Glucosamine Hydrochloride complete this catch-all group of specialised nutritional and functional additives that a full-range feed additives supplier needs to carry to support modern feed formulation.
