Findings discover rise of beneficial bacteria in poultry gut with black soldier fly-based diets

Black soldier fly-based meals can increase beneficial bacteria in poultry gut, thus promoting health and growth of birds and preempting over-reliance on antibiotics, according to findings by the Kenya-based International Center of Insect Physiology and Ecology (ICIPE).

"Since 2014, the ICIPE has led the way in incorporating insects as alternatives that are more affordable, nutritious and sustainable protein options in animal feed," the organisation said. "In particular, the centre has demonstrated that black soldier fly larvae or the proteins derived from them, can be used safely as components in feeds for poultry, pigs and fish. In poultry, such feeds have been proven to improve growth performance, the quality and quantity of meat and eggs, and overall profitability for farmers."

In a study published recently in Scientific Reports journal, ICIPE researchers show that the incorporation of black soldier fly larvae in poultry feeds can drive the presence of beneficial bacteria in poultry gut. This community of microorganisms is vital in strengthening the immunity, physical fitness and nutritional development of poultry.

Such beneficial bacteria form a protective barrier that lines the gut, preventing the growth of harmful bacteria such as salmonella, Campylobacter and Clostridium perfringens, which are among the leading causes of foodborne diseases worldwide. They also influence poultry development by enabling fermentation of the plant fibres that the birds would otherwise be unable to digest.

The researchers note that three lactic acid bacteria — Lactobacillus, Enterococcus and Bacteroides — predominate the enhanced beneficial bacteria community that arises when poultry are fed on black soldier fly larvae-based meals.

The recent findings are significant as there is an ongoing mission in Africa and globally to reevaluate and reduce the use of antibiotics in poultry farming. While the use of antibiotics to enhance growth or manage diseases in poultry has largely been useful, there are concerns about the rising resistance to antibiotics by harmful bacteria in poultry.
