Preparation of Polyester/ Micro Eggshell Fillers Composite as Natural Surface Coating

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2023
To fabricate an inexpensive surface coating with excellent mechanical properties with good water resistance and thermal diffusion, white eggshell fibers with particle size (~1micrometer) has been added by different weight percentages (1,2,3,4,5,6,7 and 8

The evolution of host‐specific variation in cuckoo eggshell strength [PDF]

Journal of Evolutionary Biology, 2010
AbstractCuckoo eggs are renowned for their mimicry of different host species, leading to the evolution of host‐specific races (or ‘gentes’) defined by egg colour and pattern. This study aims to test the prediction that another property of parasitic eggs, namely shell strength, might also have experienced divergent selection within cuckoo species.

A mixture of daidzein and Chinese herbs increases egg production and eggshell strength as well as blood plasma Ca, P, antioxidative enzymes, and luteinizing hormone levels in post-peak, brown laying hens.

Poultry Science, 2019
Dietary supplementation with the isoflavone, daidzein, has been shown to improve egg production in poultry. Additionally, providing Chinese herbs (CH) in the broiler diet has led to increased antioxidative enzyme activity. However, the combined effect of
