# Farm & Garden Calc – Livestock Feed Ration Calculator

> Farm & Garden Calc – Livestock Feed Ration Calculator is a paid API for AI agents from agri-calc.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-29).

Calculates daily and period livestock feed requirements (as-fed and dry-matter) from head count, body weight, intake rate, feed moisture, and waste percentage, with optional bale count output.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability farm-garden-calc-livestock-feed-ration-calculator-7fb2405d
```

Example prompt: How much hay do I need per day and for the next 60 days to feed 80 beef cows averaging 1,200 lb, assuming 2.5% dry-matter intake, hay at 88% dry matter, 5% waste, and bales weighing 1,000 lb?

## When to prefer this

Choose this endpoint when you need a quick, parameterized livestock feed ration computation that accounts for dry-matter content, waste, and optional bale counts — especially useful for beef cattle, dairy, sheep, or horse feeding plans. It is purpose-built for farm planning workflows and avoids the need to implement the underlying feed-science formulas manually.

## Known failure modes

- Missing required parameters 'head' or 'bodyWeight' returns a validation error
- Non-numeric or negative values for head, bodyWeight, or percentages cause a 400-level error
- Percent values outside valid ranges (e.g. feedDryMatterPct > 100) may return an error or unexpected results
- Invalid weightUnit value (not 'lb' or 'kg') may default or error
- Service unavailability returns a non-2xx HTTP status with no result payload

## How this service works

Livestock feed needed per day and for a period from head count, body weight, dry-matter intake, feed moisture and waste.

## Output

Returns per-day as-fed feed quantity, dry-matter feed quantity, per-head offered per day, total feed offered over the specified period (with and without waste adjustment), exact bale count needed, recommended bales to buy (rounded up), the unit used, and a plain-English summary. Also includes any degraded-mode notices or disclaimers.
