Interpretive Summary: Oregano essential oils have demonstrated positive effects on the growth of broiler chickens. This study was conducted to investigate the effects of Mexican oregano essential oils extracts from Lippia berlandieri Schauer (LBS) and Poliomintha longiflora Gray (PLG) on broiler weight, blood profiles, carcass variables, and meat composition. Broilers were distributed into four dietary treatments: (1) Control diet (CON), (2) CON + LBS, (3) CON + PLG, and (4) CON + LBS and PLG (LBPL). Results showed that LBS and PLG significantly maintained the body weight of broilers without increasing feed and water intake. The combined LBPL and PLG increased bloodcell numbers, low density lipoprotein, and body weights. In dissected birds, LBS treatment alone increased leg bone weight, as well as back, breast, and protein content. In conclusion, giving broiler chickens the two Mexican oregano essential oils had positive effects on growth, blood measurements, body weights, and meat protein content. These results indicated that these two Mexican oregano essential oils may be promising alternatives as growth promoters and enhancers of meat quality in broiler production. This information is of interest to poultry producers and researchers.

Technical Abstract: Oregano essential oils (OEO) have demonstrated effects on growth performance of broilers. This study was conducted to investigate the effects of Mexican oregano essential oils (MOO) extracts from Lippia berlandieri Schauer and Poliomintha longiflora Gray on performance, blood profiles, carcass variables, and meat composition of broilers. A total of 360 one-day-old Ross broilers were randomly distributed into 4 dietary treatments with 6 replicate pens per treatment and 15 birds per pen. The dietary treatments were: (1) basal diet (control, CON), (2) CON + 400 mg/kg MOO Lippia berlandieri Schauer (LBS), (3) CON + 400 mg/kg MOO Poliomintha longiflora Gray (PLG), and (4) CON + 400 mg/kg LBS + 400 mg/kg PLG (LBPL). Results showed that LBS sand PLG significantly (P < 0.05) maintained the body weight of chickens (BW) without increasing feed intake (FI) and water intake (WI) compared to the CON group. Broilers given LBPL and PLG had increased (P < 0.05) blood leukocytes, lymphocytes, low density lipoprotein (LDL), and hot carcass yields. In dissected broilers, LBS presented bone yield lower of leg, back, breast, and protein content (P < 0.05). In conclusion, supplementation with these two MOO exhibited positive effects on broiler performance, blood profiles, carcass traits, and meat composition. These results indicated that these two MOO may be promising alternatives as growth promoters and enhancers of meat quality in broiler production.
