NEWS FEED & ADDITIVE MAGAZINE May 2024 9 With our previous LCA, we shared the vision that the environmental footprint of our black soldier fly ingredients could be reduced and we have lived up to that promise: the latest DIL figures once again demonstrate an improvement in the footprint of our Protix ingredients. We look forward to translating these LCA numbers into new commercial opportunities to help our customers produce better and greener.” LCA Results: - ProteinX® insect meal reduces CO2 emissions by 78% compared with poultry meal (ProteinX: 0.832 kg CO2 eq; poultry meal: 3.8 kg CO2 eq). Poultry meal is often used in pet food and livestock feed. Compared to soy protein concentrate, an ingredient often used in aquaculture, ProteinX lowers CO2 emissions by as much as 89% (ProteinX: 0.832 kg CO2 eq; soy protein concentrate: 7.5 kg CO2 eq). - LipidX® insect fat dramatically reduces land use, using 99.9% less than coconut oil (LipidX: 0.0102 m2 land use and coconut oil: 12.98 m2 land use). Coconut oil is commonly used as a fat source in livestock and aquaculture feed as well as in pet food. - PureeX® insect meat uses a staggering 99.8% less water than poultry meat (PureeX at 0.098 m3 and poultry meat at 61.13 kg m3). Poultry meat is commonly used in pet food as a high moisture protein source. - Protix's insect frass shows only 0.01 kg CO2 eq. per kilogram of product. - Larvae, used as feed for livestock, show 0.198 kg CO2 eq. per kilogram of product.

Published in March 2024 in the journal Toxins, “Meta-Analysis of the Effects of Yeast Cell Wall Extract Supplementation during Mycotoxin Challenges on the Performance of Laying Hens” demonstrated that the inclusion of yeast cell wall extract (YCWE, Mycosorb®, Alltech, Inc., KY) supplementation during mycotoxin challenges results in an increase in layers’ body weight by 12.5 grams (g), and a substantial increase in egg production and egg weight by 4.2 percentage points and 1.37 g, respectively. The meta-analysis showed that layers fed mycotoxins experienced lower body weight (by 50g), decreased egg production (by 6.3 percentage points), and reduced egg weight (by 1.95g) compared to control-fed birds. Economic analysis suggested that the inclusion of YCWE not only supported performance but could also result in a positive return on investment. Based on results from the meta-analysis, production and profitability calculations were made, resulting in: • +2.7 eggs per hens housed (HH) over 9.5 weeks • +29.7g edible protein output per HH • 4.65:1 ROI “To the researchers’ knowledge, this is the first time a meta-analysis study has been conducted with laying hens which evaluates the influence of not only mycotoxins alone but also the use of a mycotoxin mitigation strategy on key performance parameters,” said Dr. Alexandra Weaver, global technical support for the Alltech Technology Group team.
