Animal Production Science brings together a Collection of research and review papers presented at Recent Advances in Animal Nutrition - Australia 2025 (RAAN-A 2025). The meeting was a departure from previous conferences in that it was held in Melbourne and was conducted in conjunction with the Australasian Equine Science Symposium, Nutrition and Milling Conference, Animal Nutrition Special Interest Group of the Nutrition Society of Australia and Australian Association of Ruminant Nutrition.

AN24176A new analytical procedure to replace the outdated Weende proximal feed ingredient analysis paradigm is long overdue

Gene M. Pesti

Since the 19th century, when little was known about chemical composition of feeds, gross feed analysis for trade and estimating energetic contributions has been based on the Weende method (moisture, crude protein, crude fibre, ether extract, ash and nitrogen-free extract). A new, Armidale Method, is proposed here. It consists of 13 chemical categories based on modern knowledge of feed chemistry (moisture, true protein, nonprotein nitrogenous compounds, neutral and polar lipids, sugars, oligosaccharides, starch, pectin, lignin, hemicellulose, cellulose, and ash).
