Canadian scientists have solved the mystery behind chicks who have penetrated egg shells during hatching. The researchers said they discovered a protein believed to play an important role in the hardness of calcium-based egg shells.
According to scientists, this protein increases the proportion of calcium in the outer layers of the egg, and reduces at home, making it easy to break chicks.
As long as the exit of white chickens is a mystery to scientists, how can these fragile creatures break the calcium-rich hard shell that surrounds them from each side? But the unprecedented focus of scientists on egg shell structure led them to the most likely solution to this puzzle.
It is known that part of the calcium is transferred to the skeleton of the fetus in the later stages of growth, and controls a protein recently discovered by scientists in the proportions of calcium in the layers of eggshell, and increases this percentage in the outer layer and reduce the inner layer, which is easy to break for the chicks .
"We all know that the shell of the egg is fragile, but in fact it is very strong compared to its soil, which is more solid than some minerals," says Mark Mackey, a professor at McGill University in Canada, co-author of the study. a study.
"Protein was known as osteoponet in the egg shell structure and is thought to be very important in regulating cortical and calcium-forming processes, which depend on the hardness of the crust," he said in an article in the journal Science Advance. "We discovered that the outer layer Of the egg shell is more solid, and the more turnover, the less difficult.
