Chickensextractantibacterial, SalmonellaAddition of sage extract to the diets decreased the counts of Salmonella in the liver, spleen and caecum at both sampling times, along with lower production of mucus in the chickens’ intestines. E Piesova et al., 2012
Chickensextract200-400 ppm drinking waterimmunity, Escherichia coliA significant enhancement of the immunity response of broilers was observed when the dietary concentration of sage extract increased. Further, a significant bactericidal effect of sage extract was detected for Escherichia coli, whereas it was moderate for Lactobacillus.B Rasouli et al., 2020
Chickensextract0.2% of dietantioxidant, pulmonary hypertensive, GI healthThe index of pulmonary hypertension (RV:TV) was decreased, and weight gain (days 22–35) was increased in all treatments (except for sage 0.1%) compared with control (P < 0.05). Lipid peroxidation was decreased, whereas the activity of antioxidant enzymes (GPX, CAT, and SOD) was increased in the sage 0.2% group compared with control (P < 0.05). In the lung, SOD, CAT, and GPX transcripts were decreased in the sage 0.2% group compared with control (P < 0.05). In the right ventricle of the heart, SOD and CAT transcripts were increased in the sage 0.2% group compared with other groups of chickens, whereas GPX transcript was decreased (P < 0.05). The jejunal villus length in the chickens fed sage was significantly lower than in control (P < 0.05). The ileal villus width, villus surface area, and lamina proporia thickness in the chickens fed sage (0.2%) were increased compared with control (P < 0.05).S Bahadoran et al., 2022
