Phytogenic feed additives improve broiler feed efficiency via modulation of intermediary lipid and protein metabolism–related signaling pathways
Diets enriched with phytogenic feed additives (PFA) such as AV/HGP/16 premix (AVHGP), Superliv concentrate premix (SCP), and bacteriostatic herbal growth promotor (BHGP) with essential oils have been shown to improve feed efficiency (FE) in broilers. This FE improvement was achieved via modulation... Continue reading...
