A Comprehensive Analysis of Cinnamon, Flaxseed, and Lemon Seed Essential Oils’ Effects on In Vitro Gas Formation and Nutrient Degradability in Diets

This study aimed to assess the impact of essential oils (EOs) on in vitro gas formation and degradability dairy beef cattle diets. also investigate effects different types EOs nutrient utilization rumen microbial activity. The current was conducted using a fully randomized design consisting eight experimental treatments, including two control treatments without any additives, with cinnamon oil (CEO), flaxseed (FEO), lemon seed (LEO) at concentration 60 mg/kg fresh mass. Two were used, one alfalfa silage concentrate (DC, CON-DC) other fattening (FC, CON-FC). Gas formation, dry matter (DM) digestibility, crude protein (CP) effective (ED), soluble fractions DM organic (OM) evaluated. CEO had substantial effect (p < 0.05). When added diets, they increased digestibility after 24 h incubation as compared treatments. After incubation, FCCEO FCFEO highest CP among FCLEO considerably enhanced ED, well fraction (a) passage rate 2% per hour. Treatment resulted significant increase At h, DCCEO maximum ED value. introduced diet, dramatically decreased insoluble portion (b). Compared production significantly lower presence LEO (FCLEO; p addition diets may enhance extracted from seeds (at dose diet) lowered both
