I. INTRODUCTIONThe eggshell functions as a resistance barrier protecting egg’s internal content from environmental hazards, allowing the proper embryo development during incubation. Egg quality parameters normally measured are specific gravity, vapor water conductance, weight, thickness, porosity, breaking strength, elastic modulus, static and dynamic stiffness, among others (McDaniel et al. ...

Duarte Neves (Zinpro)     The poultry industry is facing a problem with the fertility of broiler breeder eggs. The use of elevated amounts of trace minerals such as zinc (Zn), manganese (Mn), and copper (Cu) within a broiler breeder diet has been previously linked to an increase in eggshell quality, which in turn may lead to an increased fertility rate. A parameter that has been lin ...
