Are insects a solution for feeding ruminants? Legislation, scientific evidence and future challenges.

Abstract

Implications • Insects are promising alternatives to conventional pro- tein and fat sources for ruminants. • Legislation is more restrictive for the use of protein- rich insect meals than for insect oils. • Insect meals seem to have lower in vitro digestibility than conventional plant meals. • Insect products may modulate the ruminal environ- ment (e.g., CH4 emissions and biohydrogenation).
