Evaluation of Haugh Units as Indicator of Egg Quality and Freshness


Haugh unit (HU) is a good indicator of the degree of freshness of eggs and an important factor in the evaluation of egg quality. It is calculated based on the height of the egg albumen in relation to the egg weight. 


HU may be influenced by the genetic line and age of the chicken flock. As such, the choice of chicken`s genetic line is a very important factor in characterizing the egg products of the farm. Chicken breeds that are capable of maintaining high HU-index through time is preferred because of requirement and market demands for high-quality egg products. Considering that the size of eggs and its distribution in a flock changes as the hen ages, continuous evaluation of HU over time is important to have a more accurate evaluation of the flocks` egg quality.


PPQC continuously evaluates the weight and HU of the eggs of each flock of its client farms sequentially throughout the bird’s entire production cycle four days after it is laid. In this approach, a more reliable and sensitive evaluation of egg freshness and quality are obtained which is very important to satisfy the high-quality standards and requirements of its consumers. When the birds are affected by any infectious diseases, HU may also be affected showing low values. PPQC utilizes its vast database of HU values to counter-check and monitor rapidly the occurrence of any disease that may impact the production performance of the flock. In this method, we can detect possible occurrence of disease more quickly and effectively, thereby minimizing economic damage to our client farms.
