Determination of haematology and blood chemistry values in healthy six‐week old broiler hybrids

Abstract
Fourteen “comparison values” were determined for 6‐week‐old broilers. A total of 980 birds were sampled from 21 flocks to provide “comparison values” for body weight and blood characteristics. Production and management details are described and sources of variation in the “comparison values” within and between flocks are discussed. The presence of correlations between “comparison values” and between performance and “comparison values”, both within and between flocks, is investigated.
