“…Decreased EPEF, however, could not be ascribed to the liveability as this parameter was not significantly different in two groups. Higher FI, FCR and lower EPEF values in this studyare in agreement with other reports (Masouri et al, 2015;Pappas et al, 2019). The inclusion of 5% of olive byproducts into broilers' diet has been tested several times and it was reported as one of the best portions to be added into broilers' feed regarding the performance (Shafey et al, 2013;Al-Harthi, 2016;Pappas et al, 2019).…”

“…The results of the study illustrate that introduction of olivepaste flour, into broiler diet, increases the FCR, which could be attributed to the higher FI as well as to the relative final body weight of the OPF group (Masouri et al, 2015;Al-Harthi, 2016;Yi et al, 2018;Pappas et al, 2019). Moreover, EPEF value was decreased in OPF group compared to Control group.…”

“…Also, Al-Harthi (2016) stated that broilers fed with 5% of OC as olive byproduct presented increased FI and FCR, however,in contrast to our results, the EPEF was lower and BW was higher. The differences in FCR and EPEF,that olive byproducts have displayed, among studies, may be due to the variations on α-tocopherol concentration in broiler feed, but also due to the different chicken raising conditions (Rama Rao et al, 2011;Masouri et al, 2015).Also, the differences in performance could be ascribed to the different content of the crude fiber among different olive byproducts, given that certain fiber content may be related to better digestibility and other performance parameters (Al-Harthi, 2016;Pappas et al, 2019).Hence, the high content of the crude fiberin the OPF supplement that was used in the present study, could justify theincreased FI and consequently the higherFCR in the OPF group.…”

Olive oil contains a variety of antioxidants, including vitamin E. Its consumption protects against oxidative stress, which is involved in many pathological conditions, affecting animals’ development and their general welfare. The present study aimed to investigate the effect of olive paste flour (OPF) on the antioxidant status and performance of broiler chickens raised in field conditions. Total of 18.000 broilers was randomly allocated in equal numbers in two poultry houses. The chickens were grouped according to their diet as follows: Control group: chickens fed commercial poultry feed, and OPF group: chickens fed control dietsin the starter period, but they got a supplement of OPF in grower, and finisher 1 and 2periods, respectively. The birds were raised under identical field conditions (ventilation, vaccination, lighting, etc.). Antioxidant status was assessed by measuring the concentration of vitamin E in plasma, as well as the total antioxidant capacity (TAC) in plasma and muscle tissue. According to the statistical analysis of the results, the addition of OPF to chickens’ diet significantly enhanced plasma α-tocopherol concentration (p≤0.05). TAC did not show any significant differences in chicken plasma nor muscle tissue(p>0.05).Feed intake (FI) was higher in OPF group, while Body weight (BW) was lower. Liveability was similar for the two groups. The feed conversion ratio (FCR) was higher, and the European production efficiency factor (EPEF) was lower in broilers of the OPF group compared to those of the control group.Samples of roasted breast from chickens of both groups were used for organoleptic characteristics evaluation. Results showed that samples of the OPF group smelled more intensely and were more tasteful than those of the control group.However, other organoleptic characteristics did not differ. In conclusion, the results demonstrated that although the addition of OPF to chickens’ diet can cause growth retardation, it can significantly increase the plasma α-tocopherol concentration. Further studies are needed to optimize the concentration of OPF in poultry feed in order to avoid growth retardation or even to promote growth in broiler chicks.

Background: Herbal antioxidants have beneficial effects on health and performance. Meanwhile, medicinal plants and their derivations are utilized as growth and immunity promoter. Objectives: This research aimed to evaluate the effects of garlic powder and Satureja Khuzestanica essential oil (SKEO) on broiler performance, blood lipid profile, immune responses, intestinal microflora, and morphology. Methods: In total, 400 male chickens were randomly divided into five groups. Treatments included garlic powder (2 and 4%) and SKEO (400 and 500 mg/kg). Those in the control group received no intervention. On the 35th day of the experiment, the immune system of subjects was investigated, and at the end of the study, performance and blood lipid profile were analyzed. Also, the jejunal and ileal contents were separated to investigate the intestinal morphology and microflora. Results: Administration of herbal extracts was associated with improved performance, such as feed intake, BWG, and FCR (P < 0.05). Treatments could diminish the serum concentrations of lipid profile, including cholesterol, triglycerides, and LDL (P < 0.05). Meanwhile, the number of harmful intestinal bacteria was reduced by garlic (4% of diet) and SKEO (500 mg/kg) treatments (P < 0.05). Also, morphological characteristics of the intestine were improved (P < 0.05). Herbal plant supplement remarkably increased the villus length, villus length to crypt depth, and villus area (P < 0.05), but did not affect the immune responses (P > 0.05). Conclusions: This study demonstrated that dietary inclusion of herbal extracts is potentially an effective strategy for improving health and performance in broiler chickens.
