This document summarizes a central performance test for meat goats grazing on pastures in Western Maryland between June and September each year. The goals of the test are to evaluate goat performance on a pasture-only diet while exposing them to internal parasites, and to identify bucks that are more resistant or resilient to internal parasites. Goats are rotationally grazed on different forage types and supplements are provided if needed. Data collected includes weights, body condition, fecal egg counts, and other health measures. Top performing bucks are eligible for sale at the end of the test.
