Permeability of turkey eggs from hens with different hatchability rates

Abstract 1. 1. Permeability comparisons were made on egg shell and membranes from Small White turkey hens having average low (66%) and average high (90%) hatchability records after 15 weeks of production. 2. 2. Average permeabilities of egg shells with membranes in the dry state were higher in eggs from hens with a history of low hatchability (26.55 × 10 −7 cm 3 · mm · STP/sec · cm 2 · T), as compared with eggs from hens with a history of high hatchability (23.39 × 10 −7 cm 3 · mm · STP/sec · cm 2 · T). 3. 3. Lower permeability was found for egg membranes in the wet state.
