Protical is a highly absorbable source of calcium. It also contains precursors of the components of the skeleton.
By strengthening the bone structure, this product increases the calcium storage capacity in the poultry. In a laying hen, Protical limits the mobilisation of calcium of the bone marrow: the strength of the shell is clearly increased.
It results in a 30% reduction of the number of broken or downgraded eggs, and a decline in the number of cracked eggs (reducing sanitary risks i.e., feed toxicity). The pigmentation of brown eggs also becomes more uniform. The bone structure of the animal is better preserved. The laying period is extended.
