Feeding organic calcium to laying hens (FOKAL)
The breaking strength is an important quality feature of eggs, because it decisively determines the economic success of egg production. Empirical observations suggest that the replacement of conventional (inorganic) calcium feeding with organic calcium, such as calcium lactogluconate, can improve shell stability. The feeding takes place via the watering system.The project aimed to assess the impact of organic Ca on shell stability in comparison to the conventional variant in a field and a station test. Additionally, the suitability of a compressed air impulse flushing, developed by Pfalz Tec GmbH, was tested for keeping the infusion system free of Ca-related deposits over the entire project period within the framework of the field test.
The project objectives were essentially achieved. The effects on shell stability in all three egg size classes were somewhat lower than expected. A higher shell stability was particularly evident in the L-eggs in the 2nd laying period in the field trial. This manifested itself both in the breaking strength and in the correlated shell thickness. In the station test, effects were detectable in the XL grade eggs. Valuable knowledge was gained on the use and further development of compressed air pulse rinsing for the supplementation of liquid calcium as well as other nutritional supplements and medications. Significant progress was also made with regard to further automation and digitalization.
