Feed Additives Classification — Dinweys Biotech

Feed Additives Classification — Dinweys Biotech Product Guide

Feed additives are essential ingredients in modern animal nutrition, categorized by their function, composition, and regulatory status. Dinweys Biotech provides a comprehensive range of feed additives sourced from leading Chinese manufacturers. This guide explains the classification system and helps buyers understand the product categories available for global distribution.

Nutritional Feed Additives

Amino Acids

Amino acids are the building blocks of protein. Essential amino acids cannot be synthesized by animals in sufficient quantities and must be supplied through feed. Key products include:

  • L-Lysine Sulphate 70% — Essential for swine and poultry growth. Lysine is typically the first limiting amino acid in corn-soy diets.
  • DL-Methionine — Crucial for feather development in poultry and immune function across species.
  • L-Threonine — Supports gut health and mucin production, particularly in young animals.

Vitamins

Vitamin supplements ensure animals receive adequate micronutrients for metabolic function. Dinweys Biotech supplies:

  • Vitamin B2 (Riboflavin) — 80% feed grade, essential for energy metabolism
  • Vitamin C (Ascorbic Acid) — Supports immune function, particularly during heat stress
  • Choline Chloride — 60% and 50% corn cob carrier; 75% liquid. Essential for lipid metabolism, liver function, and growth performance

Minerals

  • Dicalcium Phosphate (DCP) — 17% and 18% phosphorus grades. Combined with calcium for skeletal development in growing animals and laying hens.
  • Betaine HCl — 96% and 98% purity. Acts as a methyl donor, supports osmotic regulation, and improves carcass quality in swine.
  • Betaine Anhydrous — Concentrated form for high-inclusion formulations.

Functional Feed Additives

Enzymes

Feed enzymes improve nutrient digestibility and reduce feed costs:

  • Phytase — Heat-stable and granular forms. Releases bound phosphorus from plant-based feed ingredients, reducing the need for inorganic phosphate supplementation
  • Carbohydrases — Break down non-starch polysaccharides to improve energy utilization

Phytogenic Additives

Plant-derived compounds including essential oils, herbs, spices, and extracts. Used as natural growth promoters and alternatives to antibiotic growth promoters.

Regulatory Classification

Feed additives are regulated differently across regions. Dinweys Biotech supports compliance with:

  • EU Regulations — EC 1831/2003 classification system
  • FDA/AAFCO — US regulatory framework
  • China GB Standards — Domestic Chinese feed additive regulations
  • COSUC / ANVISA — Latin American market requirements
