Rosemary Leaves as a Dietary Supplement for Growth in Broiler Chickens

Effect of Rosemary (Rosmarinus Officinalis) Dietary Supplementation in Broiler Chickens Concerning immunity, Antioxidant Status, and Performance

“…In addition, the increase in the globulin indicates the effective role of rosemary in increasing immunity due to its role in developing and protecting cells and inhibiting non-enzymatic oxidation (Houghton et al, 2007). These results came in accordance with that obtained in the study of Ali and Ghazalah (2008). The non-significant alterations in ALT activities and creatinine levels indicated the safe use of rosemary as a feed additive in broiler chickens diet on liver and kidney functions.…”

“…The essential oil isolated from rosemary was characterized by its greater content of 1,8-cineole as stated by Mathlouthi et al (2011). The main active components were camphor (11-16%), alpha-pinene (15-20%) and cineole (30-35%) which has a high degree of inhibition against many bacteria and fungi (Ali and Ghazalah, 2008). The same compounds have the antioxidant potential as studied by Rašković et al (2014).…”

“…Also, these results were supported by ELnaggar et al (2016) who found that low levels (0.25%) of rosemary give better growth performance compared to higher one. On the other hand, Al-Kassie et al (2008) stated that 0.5 and 1.0% rosemary herb supplementation in the diet clearly improved broiler growth performance at the 42 nd days of age, compared with the control treatment (Ali and Ghazalah, 2008) also found that 0.5% rosemary herb supplementation in the diet gave better results than the control treatment at the 49 th days of age.…”

Ameliorative effects of oral ginger and/or thyme aqueous extracts on productive and reproductive performance of V‐line male rabbits

“…The effect of thyme supplementation on rabbits performance is not demonstrated yet (Gerencsér et al, 2012). Otherwise, there are three possible ways to action of thymol: first is to reduce hurtful microbiota; the second is to strengthen the antioxidant system due to the polyphenols components (Abdulkarimi, Daneshyar, & Aghazadeh, 2011) and the third may be due to increased feed utilization and enhanced immunity (Ghazalah & Ali, 2008). Karangiya et al (2016) reported that ginger as a natural growth promoter could be a potential alternative for common artificial growth promoters such as antimicrobial and antioxidant.…”

Effects of supplementing broiler diets with coriander seed powder on growth performance, blood haematology, ileum microflora and economic efficiency

“…There is evidence that suggests that some herbs, spices and plant extracts have antioxidant activities, antimicrobial effects and stimulating effects on the digestive system (Hashemi, Zulkifli, Davoodi, Zunita, & Ebrahimi, 2012;Khafaga & Bayad, 2016a, 2016b. In addition, such natural additives can act on the appetite and intestinal microflora, which stimulates pancreatic enzyme secretions, which in turn increases endogenous enzyme activities and stimulates the immune system (Ghazalah & Ali, 2008). Many traditional natural additives are also used to treat diabetes, but most of the evidence for their beneficial effects is anecdotal (Al-Aboudi & Afifi, 2011).…”
