“…These authors concluded that the oil mix acted as a growth promoter, positively affecting production parameters. The current results with Mexican oregano oil were similar to those of Jamroz et al (2005), Hong et al (2012), and Silva Vázquez et al (2015). Mountzouris et al (2011) indicated that incorporating 125 and 250 mg kg -1 of a commercial phytogenic feed additive strengthened broiler production and improved efficiency and FI at the final stage.…”

“…The main active components of OEO are thymol and carvacrol, which can improve feed digestibility, due to positive effects on nutrient digestibility (Jamroz et al, 2005), and induce a higher secretion of bile acids (Hashemipour et al, 2016). Oil extracts of Origanum vulgare L. tested in broiler diets improve body weight and feed intake at 1,000 ppm (Bozkurt et al, 2009), 500 ppm (MohitiAsli and Ghanaatparast-Rashti, 2015), 100 and 250 ppm (Symeon et al, 2009), 150 and 300 ppm (Kırkpınar et al, 2011), while 200 ppm of thymol and carvacrol (Lee et al, 2003;Hassanpour et al, 2013;Silva Vázquez et al, 2015;Hashemipour et al, 2016) Park et al, 2014;Mohiti-Asli and Ghanaatparast-Rashti, 2015;Hashemipour et al, 2016).…”

-The objective of the current study was to evaluate performance, blood parameters, and carcass yield of broilers supplemented with Mexican oregano oil. A total of 162 one-day-old broilers were randomly distributed into three dietary treatments: control diet (without oregano oil or antibiotic); control diet + 0.25 g kg -1 of oxytetracycline; and control diet + 0.4 g kg -1 of Mexican oregano oil. Treatment with organ oil had positive effects on body weight at 35 and 42 days. Feed intake was significantly different at 21 and at 1-42 days; control treatment presented the highest feed intake at 28 and 35 days, while treatment with oxytetracycline had the lowest feed intake from 21 to 42 days. Weekly body weight gain was different at 42 days, in which treatment with oregano oil was the highest and control the lowest. Feed efficiency rate was significantly different at 42 and at 1-42 days; treatment with oxytetracycline and treatment with oregano oil had the best values over control treatment. Blood parameters were found different among treatments, in which treatment with oregano oil was the highest in cholesterol and high-density lipoprotein at 42 days. Carcass and blood biometric variables were not different among treatments. The amount of 0.4 g kg -1 of Mexican oregano oil in diets improves high-density lipoprotein, body weight, and feed efficiency rate of broiler chickens.

“…The isoprene derivatives, flavonoids, glucosinolates and other plant metabolites may affect the physiological and chemical function of the digestive tract. The stabilizing effect on intestinal microflora may be associated with intermediate nutrient metabolism [11,34,35]. The active principles of essential oils act as a digestibility enhancer, balancing the gut microbial ecosystem and stimulating the secretion of endogenous digestive enzymes and thus improving growth performance in poultry [36][37][38].…”

This experiment was conducted to investigate the effect of feeding garlic powder (GP) on the performance, digestibility, digestive organs, carcass cuts and lipid profile of broilers. A total of 270 day-old Cobb-500 chicks were used in the experiment. Birds were partitioned into three experimental groups of 90 birds in each. Each treatment was composed of 6 replicates with 15 birds in each. The control group was fed with a commercial starter and finisher diet. The second and third groups were supplemented with GP at the rate of 0.2% and 0.4% respectively. In the last week of experiment, 18 birds from each experimental group (3 birds per replicate) were used in a metabolic trial. At the time of termination of the experiment, the same number of birds were killed for digestive organs and carcass components measurements. Blood samples from 3 birds per replicate were collected on 3 rd , 5 th and 6 th week post feeding from wing vein for blood lipid profile determination. Total cholesterol (COL), triglycerides (TG), high density lipoprotein (HDL), low density lipoprotein (LDL) levels were determined. Results of this study showed that GP had no significant effects on broilers weight gain, feed intake (FI), feed conversion ratio (FCR), carcass cuts, visceral organs. However, GP decreased (P < 0.05) COL, TG, LDL and increased HDL levels compared to control birds. The dry matter (DM), crude protein (CP) and ether extract (EE) digestibility were improved by feeding GP. It can be concluded that GP could provide positive advantages in broilers performance.

“…The antimicrobial effect of essential oils is well established in vitro against important pathogens, including fungi (Hammer et al, 1999) and in vivo against Escherichia coli and Clostridium perfringens in broilers (Jamroz et al, 2003). Regarding reported biological activities, coriander oil showed very good antibacterial activity against some human pathogenic bacteria, namely Staphylococcus aureus, Streptococcus haemolyticus, Pseu-domonas aeruginosa, Escherichia coli, and Listeria monocytogenes (Delaquis et al, 2002).…”

Present study was conducted to investigate the effects of the dietary supplementation of coriander oil on broiler performance, blood characteristics, microbiota, and small intestine morphology measurements. A number of one-day-old broiler chickens (Ross 308) were allocated to five treatments, with four replicates according to a completely randomized design (CRD). Birds were offered either a cornsoybean meal basal diet (control), or the basal diet supplemented with 600
