BREWER’S YEAST AS A NATURAL POLLEN SUBSTITUTE

A NATURAL POLLEN SUBSTITUTE – PROTEIN SUPPLEMENT FOR BEES

Currently, feed yeast is widely used in animal nutrition due to its protein content, which has a value similar to that of animal proteins. Thus, feed yeast has become a valuable ingredient for balancing animal feed rations, especially since the use of meat, bone meal, and similar products has been banned in Europe for animal feed.

Brewer’s yeast has become an indispensable component in the production of premixes and powdered milk. Due to its irreplaceable qualities, many farmers administer it to young animals’ diets immediately after weaning (add one tablespoon of brewer’s yeast to 2 liters of milk).

It is also a valuable natural ingredient in bee feed. For bee colonies to develop naturally and reach full strength before major natural nectar flows, protein supplements are highly necessary. Such feeding is especially needed when there is no bee bread in the hive. Inactivated brewer’s yeast is the best pollen substitute, providing essential proteins and a complete complex of vitamins, minerals, trace elements, and amino acids. This is made possible by a specific technological process of instant drying and inactivation of the brewer’s yeast; any other drying method results in the destruction of yeast molecules, drastically reducing its quality.

Exceptional Nutritional Qualities

Another major advantage of using inactivated brewer’s yeast is the elimination of the risk of disease transmission. Protein feeding is generally done in the autumn and spring, but it can also be done in summer during dry periods when pollen is scarce, as this shortage limits egg-laying and weakens bee colonies.

ADMINISTRATION INSTRUCTIONS:

1) After the spring cleansing flight, place the yeast in wide-mouth containers in front of the hives. Training bees at the hive entrance is recommended. The amount of yeast collected can reach 200g/day/family.

2) IN ENERGY-PROTEIN PATTIES – Mix 6 kg of powdered sugar with 1 kg of yeast. Blend well, then add 2 kg of honey. Combine all ingredients, adjusting consistency by adding more honey if necessary. Administer in the form of 200g patties in spring, autumn, and during dry summers.

3) IN SYRUP – Maximum 10%, well blended (1 kg yeast + 9 kg syrup). Administer after honey extraction and harvest are complete. Prepare only the quantity needed for one feeding. If the mixture is not consumed within 2–3 days, remove and clean the feeders.

Why use instant inactivated brewer’s yeast for bee feeding?

– The proteins in yeast almost fully meet bees’ growth requirements.

– Yeast can stimulate appetite.

– Yeast also contains 4% alcohol, an important energy component.

Also suitable for feeding:

– Poultry: 2–6%

– Large ruminants: 8–12%

– Small ruminants: 3–6%

– Fattening pigs: 5–7%

– Breeding pigs and piglets: 2–6%

– Pigeons: 1–1.5%

– Fish: 3–4%

– Rabbits: 1–1.5% of the feed recipe

– Sheep and goats: 5–20g/head/day

– Bees: as a pollen substitute: 3 parts yeast + 3 parts powdered sugar + 2½ parts water

– Horses (medium work): min. 100g/head/day (mix 1 kg yeast in 60 kg ground feed)

– Horses (heavy work): min. 200g/head/day (mix 1 kg yeast in 40 kg ground feed)

Nutritional Parameters

Analytical Nutritional Parameters

– Protein: 40%

– Maximum Fat: 1.2%

– Maximum Moisture: 8%

– Lysine: 3.38%

– Essential Amino Acids, Complete B-Vitamin Group, Vitamins, and Minerals

In conclusion, administering brewer’s yeast can lead to:

– changes in the number and species of microbial populations

– favorable changes in volatile fatty acid content in the rumen

– positive effects on ruminal ammonia reduction

– positive impact on rumen pH

– increased fiber digestibility

Feedback from farmers indicates that adding yeast to ruminants’ diets results in better specific consumption, fewer digestive problems, improved animal health, and enhanced productive performance.
