Trace mineral transfer from hen, to egg, to chick: Improved egg quality for optimum embryonic development

During egg formation in the reproductive tract, minerals are deposited into the egg and eggshell. Firstly, the egg needs to be of high quality, and robust enough to withstand the environment for the duration of incubation. The eggshell is a vital component of the egg, not only because it contains the embryo and keeps pathogens…

Trace mineral transfer from hen, to egg, to chick: Improving hen health and laying performance

Commercial breeding hens are under great pressure to consistently produce high-quality, fertile eggs, at a high frequency. These birds’ metabolism and immunity are in hyperdrive throughout the production cycle and these need to function optimally and without fail. Moreover, the hen must be able to withstand several physiological, physical, and environmental stressors without compromising on…

Trace mineral transfer from hen, to egg, to chick: Visualising the cycle

The links between parental nutrition, reproduction efficiency, and offspring health have long been established and studied. As early as the 1930s, researchers identified, and in the 1950s started treating, the prevalence of neonatal swayback in newborn lambs caused by copper deficiency in grazing pastures. Today, it is well known that essential trace minerals play a…
