Improving the incubation results by sealing the eggshell of cracked hatching eggs with surgical tape.

In broiler breeder production, up to 2% of hatching eggs are rejected because of cracked or broken shells. Eggs with cracks give a reduced hatchability and a lower chick quality and cause economic loss. The main goal of this study was to determine the effect of sealing eggshell cracks with surgical tape on hatching parameters.

Genetic diversity of Banat Naked Neck, indigenous chicken breed from Serbia, inferred from mitochondrial DNA D-loop sequence and microsatellite markers.

Banat Naked Neck is the most important indigenous breed of chickens in Serbia. Marginalized until recently, it is becoming increasingly popular due to its adaptability and good productivity in alternative production systems. However, its history and the current breeding model pose challenges for breed preservation and future improvement.
