In the conditions of increasing environmental pollution, the development of plant-based feed additives for livestock is of great interest. The use of such additives not only improves the productivity of animals but also reduces the negative impact on the environment. In recent years, the production of plant-based feed additives based on microalgae has gained particular attention. Microalgae are a rich source of essential amino acids, vitamins, and minerals. They are also known to produce various bioactive compounds that have beneficial effects on animal health and productivity.

One promising microalga for the production of feed additives is Chlorella vulgaris. This microalga is rich in protein, vitamins, and minerals, making it an excellent supplement for livestock feed. Studies have shown that the addition of Chlorella vulgaris to animal feed can improve growth rate, feed conversion efficiency, and reduce the need for antibiotics and other growth promoters.

Another microalga that is gaining interest for the production of feed additives is Spirulina platensis. Spirulina is rich in protein, vitamins, and minerals, as well as bioactive compounds such as phycocyanin and gamma-linolenic acid. These compounds have antioxidant, anti-inflammatory, and immunomodulatory effects, making Spirulina an excellent supplement for livestock feed.

In addition to microalgae, other plant-based feed additives such as yeast, enzymes, and plant extracts are also gaining popularity in the livestock industry. These additives can improve nutrient utilization, reduce the need for antib
