Influence of fucus algae on milk quality and cow productivity

Abstract

Increasing the productivity of farm animals without harming their health is one of the most important tasks of modern animal husbandry. One of the solutions is the use of feed additives that can compensate for the deficiency of nutrients and biologically active components that can positively affect the productivity of animals and the quality of the final product. Of particular interest in this area are fucus waters rich in iodine, microelements (selenium, zinc, iron), vitamins (A, D, E, group B), characteristic polysaccharides (fucoidans, alginates) and omega-3 fatty acids. Alginates, for example, improve the functioning of the gastrointestinal tract, and fucoids have anti-inflammatory and antioxidant effects. The use of powder based on fucus liquid is a promising direction, especially for regions with accessible raw materials, such as the Leningrad Region. The purpose of the study is to study the effect of fucus water additives on the productivity of cows and the quality of milk. During the study, we found that when using a feed additive containing fucus water, there was a sharp increase in the norm in the experimental group (by 11%), and the effectiveness in terms of milk quality was observed through a significant increase in the percentage of fat in the experimental group (by 10.8%). There was also a reliable decrease in the level of urea milk in the experimental group (by 3.4% and 7%). The results can be used in safe and applicable feed solutions to improve productivity in animal husbandry, which is especially important at present, since there is a steady trend towards increasing the level of highly productive animals, such methods often cannot be fully satisfied with standard diets.
