Insect farming for feed: yeast probiotics solutions

Phileo dash

After millions of years of free-life evolutionary success, insects’ massive production has resulted in health challenges for domesticated colonies, and for insect producers the necessity to implement practices to improve productivity from this new kind of ‘livestock farming’.


Insects as sustainable alternative proteins

Beekeeping and silkworm production have been examples of this practice for hundreds of years. More recently, Mediterranean Fly production has emerged as a modern example for biological control proposes. Insects that are produced as a new source of protein are a further example.


As these industries grow in size, new health and production issues are expected to arise, making business sustainability for the species more challenging. Our well recognised probiotics and primary yeast products, backed by years of research, are driving us towards our goal of providing solutions that maximise insect productivity and therefore contribute to food security and natural resource sustainability.

Yeasts in insects

Sterile insects

Mostly represented by the Mediterranean Fly species, several facilities around the world have massive rearing operations that are designed to reduce the current damage caused to fruit harvests. This work requires a continued improvement in feed conversion rates to produce more male insects, which live longer in nature, to accomplish their biological control function. To meet this industry need, we provide reliable sources of protein based on primary yeast products, including Torula.

Protein insects

The steadily increasing demand for high-quality animal protein, needed to feed a fast-growing global population, has forced mankind to direct its attention towards insects as one of the most stable and sustainable sources of protein. Newly domesticated species, produced under close confinement on an industrial scale, are expected to constitute a robust growth industry over coming years.

Zootechnical performance

Performance improvement in both adults and larvae is an objective that can be reached by using high quality and sustainable nutrition to maximise productivity through increased laying rates, egg hatching and growth.

The growth performance of Black Soldier Fly (BSF) and Yellow Meal Worm (YMW) was boosted when 0.2% of Actisaf® was added to feeding media.

Health management

Health could be a critical issue in free-life insect species with a long history of domestication, as well as in newly domesticated insects that are reared under confinement in large-scale production units. In both cases, the stress caused by environmental conditions and changes in feeding regimes, could put a brake on the species’ natural defences against microorganisms, or modify gut probiota causing mortalities and morbidities, resulting in significant losses.
