“…The treatments were: negative control, without antimicrobials and anticoccidials; positive control -feed supplemented with 10 ppm enramycin and 42 ppm salinomycin; lemongrass -feed containing 120 mg of lemongrass essential oil for each kg -1 of animal body weight; L. rotundifolia -feed containing 120 mg of L. rotundifolia essential oil for each kg -1 of animal body weight; combination -feed with the mixture of the two essential oils. The dose used was defined from the antimicrobial activity presented by the essential oils of L. rotundifolia (Souza et al, 2015) and lemongrass (Azevedo et al, 2016) in preliminary in vitro tests.…”

Use of Lippia rotundifolia and Cymbopogon flexuosus essential oils, individually or in combination, in broiler diets

et al. 2017

-This study investigated the effects of Cymbopogon flexuosus and Lippia rotundifolia microencapsulated essential oils on broiler performance and carcass yield. One hundred and fifty mixed-sex Cobb broiler chicks were used, from one day up to 42 days of age, in a completely randomized design, with five treatments and three replicates of ten birds each. The treatments were: negative control (basal diet), positive control (diet with enramycin and salinomycin), and three diets with microencapsulated essential oils from lemongrass, L. rotundifolia, and combination with 50% of both. The performance and carcass yield were not affected by the treatments. The intestine absolute weight was lower in the combination treatment compared with the negative control treatment and the lemongrass essential oil. The intestine relative weight was higher in the treatments with lemongrass and L. rotundifolia essential oils in relation to the combination. The liver relative weight was lower with the lemongrass essential oil and the combination compared with the treatment with the L. rotundifolia essential oil. The trial could not find results enough to recommend the use of the lemongrass and L. rotundifolia essential oils as an additive in broiler diets.

“…According to Gomide et al (2013), the major component of its essential oil is β-myrcene. It also has proven antimicrobial activity (Souza et al, 2015). There are no reports in the literature of the use of these two species as additives in animal feed.…”

“…The high mortality rates found may be due to environmental conditions prior to incubation, or immersion time during the disinfectant application process. Egg contamination by bacteria occurs soon after posture (Wall et al, 2008), which can also lead to internal contamination of the egg by migration of bacteria from the surface of the eggshell (De Reu et al, 2006b), affecting incubation rates. The hatching rate may also have been affected by the egg handling conditions, egg storage (high temperatures) and storage time conditions in the poultry house, and the age of the birds, which were, on average, more than 100 weeks old.…”

“…Several disinfectants and application methods are available on the market; however, their efficiency is questionable due to considerable resistance of the microorganisms, and egg losses due to contamination at the poultry houseand during the incubation process. Quaternary ammonia is one of the main commonly used disinfectants; it has high bactericidal potential and low toxicity (Grezzi, 2006;Spinosa et al, 2006). However, its action is considerably reduced in the presence of organic matter (Jaenisch et al, 2010).…”

SUMMARY The effect of the disinfection of fertile eggs of free-range poultry with essential oils from Cymbopogon flexuosus and Lippia rotundifolia was evaluated. The treatments applied to the eggs were (v v-1): 1% essential oil from C. flexuosus (CF), 1% essential oil from L. rotundifolia(LR), 0.1% CF + LR, and 0.1% quaternary ammonia (QA) (positive control). The eggs were incubated for 21 days, the birds from hatched eggs were counted and weighed, and not hatched eggs were opened and examined macroscopically to determine egg fertility, and embryonic death time. The antimicrobial action of the essential oils was determined through quantitative analyses, considering aerobic mesophylls, filamentous fungi, yeasts, and total coliforms. Mortality was high in the treatments, especially in the treatment with essential oil from C. flexuosus. The highest hatchability was found in the treatment with QA. The treatments with singly or combined essential oils were more efficient in decreasing microbial count than QA. The essential oils from C. flexuosus and L. rotundifolia reduced the microbial load of fertile eggs of the free-range poultry evaluated.

“…Cymbopogon flexuosus (lemon grass) and Lippia rotundifolia (chá-de-pedestre) essential oils can be used as alternative performance enhancers due to their in vitro antimicrobial action, and they can promote diet stability (Assis et al, 2017;Azevedo et al, 2016;Souza et al, 2015). Cymbopogon flexuosus, also known as grass balm, is native to Asia (May et al, 2008).…”

Blood parameters and hepatic histopathology of broilers fed rations supplemented with essential oils

et al. 2019

This study aimed to evaluate the hematological profile, hepatic function, and histopathology of mixed-sex broilers fed rations supplemented with microencapsulated essential oils from Cymbopogon flexuosus (lemon grass) and Lippia rotundifolia (chá-de-pedestre). One hundred and fifty Cobb chicks were housed in cages from 1 to 42 days of age in a completely randomized design, with six replicates with five chickens in each of five treatments (150 total chicks): basal diet without antibiotic growth promoter (negative control), diet with enramicina and salinomycin (positive control), diet with lemon grass essential oil, diet with L. rotundifolia essential oil, and diet with a mixture of lemon grass and L. rotundifolia essential oils. Mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) were significantly lower in untreated broilers (negative control group). Gender was not associated with erythrogram values, but aspartate aminotransferase activity (AST) was higher in females. Gamma-glutamyl transferase (GGT) was higher in chicks in the group that received rations with lemon grass oil. Broilers that received L. rotundifolia oil developed more hepatic lesions, although no effect of sex was observed related to the lesion score. Biliary hyperplasia and fibroplasias were observed in all groups, with higher histopathology scores in broilers that received diets containing L. rotundifolia oil. Mixed-sex broilers fed rations supplemented with lemon grass and L. rotundifolia essential oils have normal complete blood counts and unspecific hepatic lesions and are characterized by lipidosis, hyperplasia of the bile ducts, and fibroplasia.
