Dairy cows' nutrition should be balanced because important quantities of mineral salts, especially calcium and phosphorus, but also magnesium, potassium, sodium, chlorine etc. are eliminated through milk. Also, mineral substances have a training role in the body, participating in a high proportion in the structure of supporting tissues, as well as a functional role by maintaining the main physiological functions. The use of zeolites in the form of volcanic tuff can influence the mineral and hematological parameters in the blood of cows in the calving period, as well as lactating cows. A lower variation in calcium, phosphorus and magnesium in blood is observed when using the volcanic tuff in the cows' feed during the pre-calving period and the first 2 weeks after calving. In the pre-calving and the first 2 weeks after the calcification, the values of erythrocytes, leukocytes and hemoglobin have lower values but are not statistically provided. During the lactation period, the three hematological parameters of the cows were physiologically normal, not being influenced by the administration of zeolite to the ration of dairy cows.
