All research points out that consumption of cattle scat containing dung beetle larva is observed in the wild. In 2023 I increased the protein content in the pyxis diet by adding ground up dry lava , and was surprisingly disappointed at the outcome!. Ova production was up by almost 20% but the fertility (viability) dropped to 0%!!!! . I want to know if any other pyxis breeders here have experienced this. In 2024 , the diet was reconstituted to pre 2023 and viability was back to normal. I do not have any data yet for 2025 yet but I did move the groups , hence the data will be questionable. Any feedback is much appreciated .
