What is the difference between yeast culture and beer yeast powder?

The main differences between yeast culture and beer yeast powder are as follows:

Compositional differences

Yeast culture:

It is a complex mixture that contains yeast cells and numerous components produced during fermentation, such as fermentation metabolites (such as organic acids, oligosaccharides, peptides, amino acids, nucleotides, vitamins, minerals, etc.), nutrients within yeast cells, and yeast cell walls. These metabolites play an important role in regulating animal physiological functions, such as organic acids helping to maintain a suitable pH level in the gut, and oligosaccharides acting as prebiotics to regulate gut microbiota.

Beer yeast powder:

The main components are the processed and dried substances of yeast cells themselves. The core components include protein, carbohydrates (such as glucan and mannan), fat, various vitamins (mainly B vitamins), and minerals. The focus is on these basic nutrients contained in yeast cells, which are relatively simpler and more direct in composition than yeast cultures.

Different production processes

Yeast culture:

It is achieved by fermenting yeast in a suitable culture medium under specific cultivation conditions. During this process, yeast continuously grows and reproduces, producing various metabolic products. After a series of treatments (such as concentration, drying, etc.), the entire cultivation system is transformed into products, with the aim of retaining as many beneficial components as possible produced during the fermentation process.

Beer yeast powder:

Usually a byproduct of beer production, it comes from yeast slurry after beer fermentation, which is processed through washing, separation, drying and other processes. The focus is on obtaining yeast cells themselves and making them into powder products that can be stored and applied.

Different functional focuses

Yeast culture:

It focuses more on regulating the gastrointestinal microbiota of animals, stimulating their immune system, and improving their digestive function through the rich metabolic products it contains. It can enhance the digestive and absorption capacity of animal intestines, improve the utilization efficiency of nutrients, promote healthy growth of animals, and greatly help improve their production performance, especially in improving intestinal health and disease resistance.

Beer yeast powder:

It mainly provides high-quality and rich nutrition for animals, such as supplementing protein, vitamins, and minerals, to meet the nutritional needs of animal growth, development, reproduction, and other processes. It plays a role in promoting animal growth and improving feed efficiency, and is more inclined to be used as a nutritional fortifier.

Differences in application scenarios

Yeast culture:

Widely used in various fields such as livestock and poultry farming (such as pigs, chickens, cows, etc.), aquaculture, etc., it is particularly suitable for breeding scenarios that want to improve animal intestinal health, enhance overall breeding efficiency, and enhance animal disease resistance. It is often used as a functional additive.
Beer yeast powder:

It can also be applied to various animal husbandry, but more often it is used as a nutritional supplement feed material to supplement some of the nutritional gaps in animal feed and improve the nutritional quality of the feed. For example, adding beer yeast powder to some homemade mixed feed can increase nutritional richness.
