Where this comes from.

Listings on Cowbrowse v1 are seeded reference inventory — programmatically generated from real breed and country data, structured to demonstrate the marketplace experience and to seed the AI search index. Each listing is grounded in authoritative breed-region data: only breeds that are genuinely raised in a given country appear in listings from that country. Prices reflect approximate local market values as of late 2025.

Real seller-posted listings, USDA AMS feeds, AuctionsPlus integration, and CEPEA boi-gordo data will replace seeded data progressively in v2.

Our breed dataset covers ~60 of the world's most significant cattle breeds across Bos taurus, Bos indicus, composite, and notable rare lines. Information on origin, climate fitness, typical weights, temperament, and key facts is synthesized from:

• Felius, M. (1995). Cattle Breeds: An Encyclopedia. Misset.
• Hall, S. J. G. & Clutton-Brock, J. (1989). Two Hundred Years of British Farm Livestock. British Museum.
• Livestock Conservancy Conservation Priority List (2023).
• Rare Breeds Survival Trust (UK) Watchlist.
• Breed society publications (Highland Cattle Society, Belted Galloway Society, American Brahman Breeders Association, etc.).

The 50-country corpus is anchored on FAO and USDA-FAS herd-size figures (most recent available year). Centroid coordinates for cattle-density regions come from country-specific agricultural statistics ministries and Wikidata. Currency assignments use ISO 4217.

• FAOSTAT — fao.org/faostat
• USDA Foreign Agricultural Service — fas.usda.gov
• National statistics offices (INDEC, IBGE, ABS, NSSO, etc.)

Price tickers and historical series are seeded from the following public sources. We intend to refresh these on a daily/weekly cadence in v2 via direct ingestion.

• USDA AMS Market News — ams.usda.gov/market-news (US feeders, fed cattle, slaughter cows)
• CEPEA-Esalq — cepea.org.br (Brazil boi gordo arroba index)
• Meat & Livestock Australia (MLA) — Eastern Young Cattle Indicator (EYCI)
• European Commission DG Agri — EU young bull and dairy cow prices

USD-cross rates used for filter and ranking calculations are static snapshots taken in late April 2026. We do not represent these as real-time. For genuine FX needs, please consult a current source. We intend to integrate openexchangerates.org or a comparable live feed in v2.

Listing imagery in v1 uses placeholder photos served from picsum.photos as deterministic seeded URLs. Real, breed-appropriate Unsplash photography (with per-photo attribution stored on each listing) will replace these in an upcoming revision.

Journal article illustrations are SVG line work created in-house, with optional additional licensed editorial photography from Unsplash where used.

Cowbrowse's natural-language search and chat are powered by Google's Gemini 2.5 Pro (chat with tool use) and Gemini 2.5 Flash (intent extraction). The model never invents listings — every cattle reference returned to a user is grounded in our actual listing inventory via tool calls. Breed, market, and country information presented in chat is drawn from the reference datasets cited above.
