Mortality, production and quality of eggs of different rearing systems
(2018-07-01)
The conventional production of eggs in cage systems is intense and compromises the laying hens welfare. More demanding consumer markets have been pushing to abolish the use of cages and thus provide better welfare in poultry ...
Effect of the Inclusion of Organic Copper, Manganese, And Zinc in The Diet of Layers on Mineral Excretion, Egg Production, and Eggshell Quality
(Facta-fundacio Arnco Ciencia Tecnologia Avicolas, 2015-10-01)
This study aimed at evaluating the replacement of inorganic copper, manganese, and zinc sources by organic sources in the diet of laying hens during the second laying cycle in trace mineral excretion, egg production, and ...
Correlations between thermal environment and egg quality of two layer commercial strains
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2008-06-01)
