Effect of diatomaceous earth on parasite load, egg production, and egg quality of free-range organic laying hens.
The effectiveness of diatomaceous earth (DE) as a treatment against parasites and to increase feed efficiency and egg production of organically raised free-range layer hens was evaluated in 2 breeds of commercial egg layers [Bovan Brown (BB) and Lowmann Brown (LB)] that differ in their resistance to internal parasitic infections. Half the hens of each breed were fed diets supplemented with DE (...
متن کاملDynamics of Salmonella Shedding and Welfare of Hens in Free-Range Egg Production Systems.
The current study investigated the effect of environmental stressors (i.e., weather changes) on Salmonella shedding in free-range production systems and the correlations with behavioral and physiological measures (i.e., fecal glucocorticoid metabolites). This involved longitudinal and point-in-time surveys of Salmonella shedding and environmental contamination on four commercial free-range laye...
متن کاملS83 Egg Shell Colour in Free Range Laying Hens
Loss of shell colour in brown-egg layers is a shell quality issue in Australia and is periodically associated with free range egg production. This study investigated the loss of shell colour that occurs in some flocks of free range laying hens. Hens laying pale-coloured egg shells on a commercial free range farm were transferred to cages in an experimental facility. Egg quality was measured imm...
