Yeast is also a relatively ideal feed for bees, as it can supplement unknown nutritional factors, vitamins, and essential nutrients. In artificial pollen, the most suitable yeast is brewer's yeast. Brewer's yeast is a high-quality protein source, rich in B vitamins, amino acids, minerals, and unknown growth factors. In recent years, many beekeepers have used yeast powder as a substitute for pollen to feed bees, achieving good results. Experimental results show that yeast powder can fully serve as a substitute for pollen.
