Abstract
The article presents the results of research on developed targeted functional feed additives for the prevention of animal diseases, preservation of agricultural animal microbiota, improvement of quality indicators of meat and milk, and increasing the productivity of agricultural animals. One of the effective ways to improve industrial technology in the direction of ensuring a normal physiological status, normalizing physiological processes, and increasing animal productivity is the use of innovative forms of functional probiotic feed additives, which are bacterial formulas from a consortium of live microbial cultures, sorbed on highly dispersed silica and biologically active components — extract and meal of milk thistle (Silybum marianum). The work highlights the results of the application of targeted feed additives in cattle and pig farming and their influence on the growth intensity, milk productivity indicators, quality indicators, and chemical composition of meat and milk.
The live weight in the experimental groups of calves was 4.7% and 3.8% higher compared to the control, in the second experimental compared to the first — by 0.9%, and the live weight of young pigs in the experimental groups was 99.83 ± 0.13 kg and 101.19 ± 0.12 kg, which is 3.5% and 4.9% more than the analogous indicator in the control group. The feed additives “Bioprotectin KD powder” and “Bioprotectin KD granules” also influence the indicators for the carcass yield of the experimental groups, which prevailed over the indicators of the control groups, and the meat was characterized by an optimal ratio of fat and protein.
