Effect of a Phytomineral Complex and an Enzyme Preparation on the Absorption of Nutrients and the Energy Balance of Calves' Diet

Cost-effective animal husbandry directly depends on the correct breeding of replacement young animals using diets corresponding to the feeding rate for all nutrition elements of the detailed system. Critical to these diets are biogenic elements, pivotal in enzymatic reactions and immune defense. However, specifics on enhancing nutrient absorption through dietary supplements remain underexplored, particularly in the context of calves' preweaning growth. This study aims to evaluate the impact of a phytomineral complex and an enzyme preparation, GlucoluxF, on the digestibility and assimilation of nutrients in preweaning calves' diets. This scientific and economic experiment was performed on 64-month-old black-and-white breed heifers divided into four groups with balanced randomization to ensure representativeness. Each group was kept based on the group method and received the same diet following the keeping technology adopted on the farm. Apart from the main diet received by all the experimental groups, the second group additionally received a phytomineral complex at the rate of 100 mL per head per day, the third group received an enzyme preparation GlucoluxF at the rate of 500 g per t of compound feed and the fourth group received both feed supplements in the same doses. The obtained data allowed us to establish the effectiveness of the combined use of the feed supplements in the diet of the replacement young animals, which activated the processes of digestion and assimilation of nutrients in the diet and increased the amount of pure energy for the anabolic processes of the body. Findings suggest that the strategic addition of a phytomineral complex and GlucoluxF to the diets of preweaning calves can significantly enhance the digestibility and assimilation of nutrients. This study contributes to the field by providing a detailed examination of the effects of these dietary supplements, underscoring their potential value in advancing nutritional strategies for young livestock
