Calcium Montmorillonite (CM) administration test - summary-level blood biochemical, immune cell, cytokine, and carcass data from Japanese Black fattening cattle.

This dataset contains summary-level measurements (minimum, median, maximum, mean, standard deviation, standard error, and 95% confidence intervals) derived from Japanese Black fattening cattle enrolled in a controlled administration study evaluating the effects of CM supplementation on growth performance, blood biochemical parameters, immune cell subsets, cytokine mRNA expression, and carcass traits. All personal identifiers, farm-level information, individual animal records, and management data have been removed. No individual-level data are included in this dataset to ensure confidentiality and prevent identification of specific animals or farm practices.
