Revenue from Contract with Customer [Text Block] | 13. REVENUE We primarily offer the First Defense® product line to dairy and beef producers to prevent scours in newborn calves. This line offers two distinct platforms: veterinary biologics providing scours protection against E. coli, coronavirus, and rotavirus and functional feed products delivering concentrated bioactive colostrum proteins. Generally, our products are promoted to veterinarians as well as dairy and beef producers by our sales team and then sold through distributors. Our primary market is North America. We do sell into select international regions and may expand this international reach in the future. There were no material changes between the allocation and timing of revenue recognition during the three-month or nine-month periods ended September 30, 2025 or 2024. We do not have any contract assets for which we have satisfied the performance obligations, but do not yet have the right to bill for, or contract liabilities such as customer advances. All trade receivables on our balance sheets are from contracts with customers. We incur no material costs to obtain contracts.
