one hundred and eighty 28-days-old arbor acres broiler birds were utilized in a 28 day experiment to investigate the effect of replacing bone ash with eggshell meal in the diet of broiler birds on their nutrient digestibility and blood parameters. five experimental diets tagged t1, t2, t3, t4 and t5 were formulated to be isocaloric (2865.53 kcal me/kg) and isonitrogenous (20% crude protein) suc...
Eggshell (ES) is an alternative source of calcium carbonate that efficiently removes heavy metals in aqueous solution. The adsorption capacity ES depends on their physico-chemical properties and the influence experimental conditions, but majority reports, not all reaction parameters related to process are available, mechanism systematically studied. In this contribution, use waste reported esta...
Nowadays, almost every industry needs to undergo green and sustainable industrial revolution due pollutions like waste dumping noise that deteriorating the environment. Therefore, feasibility study on application of eggshell as partial cement replacement in lightweight foamed concrete was conducted by aiming solve environmental acoustical issues, i.e. reduce improve acoustic properties. In this...
The avian embryo resorbs most of the calcium for bone formation from the calcite eggshell but the exact mechanisms of the resorption are unknown. The present study tested whether this process results in variable fractionation of the oxygen and carbon isotopes in shell calcium carbonate, which could provide a detailed insight into the temporal and spatial use of the eggshell by the developing em...
No single hypothesis is likely to explain the diversity in eggshell coloration and patterning across birds, suggesting that eggshell appearance is most likely to have evolved to fulfill many nonexclusive functions. By controlling for nonindependent phylogenetic associations between related species, we describe this diversity using museum eggshells of 71 British breeding passerine species to exa...
