Effect of nanostructured zeolite on morphobiochemical indicators of duck blood

The article is devoted to the study of morpho-biochemical indices of duck blood when using nanostructured zeolite during the period of embryogenesis by the in ovo method and during the period of postnatal ontogenesis - in feeding the young. During the study, three groups were formed: a control group and two experimental groups, which received nanostructured zeolite by the in ovo method and with the main diet in the amount of 1% of the dry matter of the feed. Morphological studies of the blood showed an increase in the number of erythrocytes by 1.7 and 6.1% and hemoglobin content by 3.6 and 7.8% (P
