The article introduces a long-term analysis of statistics and experimental research in domestic animal farming. Dairy cattle breeding is the dominant industry in Russian livestock farming. Its annual productivity has reached 6000 kg of milk per cow, while some farms and regions have brought this indicator up to 8000–10 000 kg. Unfortunately, the quality of milk, meat, and other livestock products is often neglected in favor of productivity. Human health is believed to depend on nutrition. However, this dependence requires more specific evidence. For instance, the exact effect of livestock product quality management on the life and longevity of the population still remains unknown. Some studies revealed that pig breeds differ in the cholesterol status of fat; other research teams invented a high-quality green alfalfa dry feed, which provides animals with biologically active substances and normalizes metabolic processes. This review highlights some promising scientific directions in fundamental and applied knowledge that can be beneficial to human health.
