“…In this study, the addition of TS essential oil at the levels of 10 and 15 μl per kg LW of lambs did not adversely affect LW or LW gain. The intake of concentrate feed and lucerne hay was similar which is in accordance with the results of other in vivo studies examining thyme oil and active compounds of this genus (carvacrol, thymol, γ-terpenene and p-cymene) (Bampidis et al, 2005;Chaves et al, 2008;Wang et al, 2009;Vakili et al, 2013). Simitzis et al (2008) also observed that supplementation of concentrate feed oregano essential oil (1 ml · kg −1 ) did not affect LW or LW gain.…”

“…In similar experiments conducted in lambs fed on diets supplemented with cinnamaldehyde, sensory evaluation showed no changes in meat juiciness, tenderness and overall palatability as well as flavour intensity or desirability (Chaves et al, 2008a and2011). Moreover, incorporation of cinnamaldehyde in feedlot cattle diets did not influence meat sensory characteristics and quality grade (Yang et al, 2010a).…”

“…Previous studies similarly demonstrated no effect of dietary cinnamaldehyde supplementation on growth performance and carcass characteristics in lambs (Chaves et al, 2008a(Chaves et al, , 2008b(Chaves et al, and 2011. No significant differences in carcass weight were also observed after Lambs were fed ad libitum; control group was fed on the basal diet, and the cinnamon supplemented group was fed on the basal diet supplemented with cinnamon essential oil (1 ml/kg concentrated feed).…”

“…Dietary supplementation with cinnamon essential oil did not significantly affect the weights of the internal organs (P > 0.05) (Table 3). However, in a previous study, lambs fed on a diet supplemented with cinnamaldehyde at a concentration of 0.2 g/kg tended to have heavier livers than those fed with the control diet (Chaves et al, 2008a). On the other hand, in a recent study of the same authors, no effect of cinnamaldehyde dietary supplementation (0.2 to 0.4 g/kg) on lamb liver weight was observed (Chaves et al, 2011).…”

No significant differences in daily feed intake were observed in beef cattle supplemented with cinnamaldehyde (Yang et al, 2010a) or eugenol (Yang et al, 2010b) at the concentrations of 0.4, 0.8 and 1.6 mg per steer per day, respectively.…”

A trial was conducted to examine the effect of cinnamon essential oil supplementation on lamb growth performance and meat quality. Sixteen male lambs were randomly assigned to two groups. The first group served as control and was given a basal diet, and the second group was given the same diet supplemented with cinnamon oil (1 ml/kg of concentrated feed) for 35 days. Incorporation of cinnamon oil did not affect growth performance (P > 0.05). Meat pH, colour, water-holding capacity, shear force, intramuscular fat and lipid oxidation values of longissimus thoracis muscle were not significantly influenced by cinnamon oil supplementation ( P > 0.05). The post-inoculation counts of Salmonella enteritidis and Listeria monocytogenes on raw meat during refrigerated storage for 6 days did not differ ( P > 0.05) between the two groups. The results show that cinnamon oil supplementation may not have the potential to improve lamb growth performance and meat quality characteristics.

BACKGROUNDEssential oils extracted from cinnamon bark and oregano are rich in cinnamaldehyde and carvacrol and show potential for promoting animal performance. However, their impact on rumen biohydrogenation and the fatty acid composition of meat has not been reported. The hypothesis of this study was that a blend of essential oils rich in cinnamaldehyde and carvacrol would inhibit rumen biohydrogenation and promote the accumulation of polyunsaturated fatty acids (PUFAs) in lamb meat. The present study evaluated the effect of a blend essential oil (EO) rich in cinnamaldehyde and carvacrol on the nutrient digestibility, rumen biohydrogenation, growth performance, and fatty acid profile of the longissimus lumborum of lambs.RESULTSSixty male lambs with an average age of 84 ± 0.98 days and initial body mass of 25.4 ± 0.29 kg (mean ± standard deviation) were assigned randomly to four diets, and supplemented with 0 (EO0), 30 (EO30), 60 (EO60), and 120 (EO120) mg kg−1 dry matter of EO for 60 days. Although dry matter and neutral detergent fiber digestibility all showed a linear decrease (P ≤ 0.02) with increasing quantities of EO, final body mass and average daily gain increased linearly (P = 0.04), and average daily weight gain (ADG)/dry matter intake (DMI) tended to increase linearly (P = 0.07). Increasing EO supplementation resulted in a linear decrease in total volatile fatty acid concentration, acetate molar percentage, and acetate‐to‐propionate ratio (P ≤ 0.03), with the EO120 treatment being lower than the other EO treatments (P ≤ 0.05). Seven lambs from the EO120 treatment and seven lambs from the EO0 treatment were randomly slaughtered. It was observed that the proportions of C18:2n6c and PUFA in longissimus lumborum were higher in the EO120 treatment than the EO0 treatment (P ≤ 0.05). The relative abundance of Firmicutes in the rumen was decreased by the EO120 treatment in comparison with the EO0 treatment (P ≤ 0.05). Furthermore, the predicted relative abundances of genes encoding for conjugated linoleic acid reductase tended to decrease with the EO120 treatment (P = 0.06).CONCLUSIONSWe demonstrated that supplementation of the EO blend rich in cinnamaldehyde and carvacrol can enhance lamb growth performance and promote the deposition of desirable PUFAs in meat. © 2024 Society of Chemical Industry.
