Zinc (Zn) has a number of key roles relating to cell signalling, cell activation, gene expression, protein synthesis, apoptosis and is crucial for the development of immune cells. Damage to the linings of the gastrointestinal tract is observed during Zn deficiency. Since a few years it has been suggested the existence of the novel interrelationship between bone and gut:gut–bone axis.

The aim was to establish changes of morphological, geometric and mechanical parameters of femur in chickens supplemented with organic and inorganic Zn.

One-day-old Ross 308 male chickens were split into three groups each of 20 chickens. The birds were fed ad libitum with basal diets adequate to respective growth periods and had free access to water. Chickens were divided into three groups: the control (Zn-deficient group) and two groups supplemented with organic (zinc oxide) or inorganic (glycine chelate) Zn in the premix, which contained about 100% of the daily need of Zn. The requirement of mineral components in diet was based on nutritional recommendations for Ross 308 broiler chickens, amounting to 100 mg/kg−1 of Zn. The birds were slaughtered at the age of 42 days. Tibiae were isolated and their weight and length were measured. Geometric (cross section area; cortical index; and mean relative wall thickness) and mechanical parameters like maximum elastic strength and ultimate strength, were determined. Additionally, the concentration of IGF, GH, osteocalcin and leptin was determined.

Obtained results showed that there was no diffrence between Zn-deficient group and supplemented with organic or inorganic groups of chickens.

Diet supplementet with Zn in organic or inorganic form did not influence bone development in chickens.
