Effect of feeding dried sweet orange (Citrus sinensis) peel and lemon grass (Cymbopogon citratus) leaves on growth performance, carcass traits, serum metabolites and antioxidant status in broiler during the finisher phase

Abstract

The current experiment was conducted to evaluate the effects of feeding dried sweet orange peel (SOP) and lemon grass leaves (LGL) as feed additives on broiler growth performance, serum metabolites, and antioxidant status. A total of 192-day-old (Ross 308) broiler chickens were distributed randomly into 4 dietary treatments with 4 replicates per each treatment. The dietary treatments included a control diet without any feed additive (T1), a diet containing 0.8 % SOP (T2), a diet containing 0.8 % LGL (T3), and a diet containing combination of 0.4 % SOP + 0.4 % LGL (T4) was fed during the growth period from 22 to 42 days. Feed intake (FI), body weight gain (BWG), feed conversion ratio (FCR), carcass traits, serum components, and antioxidant status were measured. At the end of the experimental period, the results indicated that supplementation of SOP and LGL alone or in combination did not significantly (P > 0.05) affect BWG, FI, FCR, and carcass characteristics in broiler chickens. Serum total protein was increased significantly (P < 0.05) in T3 and T4 compared to the other treatments. Also, serum globulin increased significantly (P < 0.05) in the treated groups. Serum glucose, low density lipoprotein, triglyceride, and very low density lipoprotein decreased significantly (P < 0.05) in the treatment groups, while cholesterol and high-density lipoprotein decreased in T2 compared to the other groups. Significantly (P < 0.05) higher total antioxidant status was observed in T2 compared to the other treatments. In conclusion, these results indicate that SOP, LGL, and their combination may positively modify some serum components and the antioxidant status without any beneficial effect on growth performance and carcass traits in broiler chickens.

Orange peel fragment improves antioxidant capacity and haematological profile of Nile tilapia subjected to heat/dissolved oxygen‐induced stress

“…As to FI and SUR are concerned, the orthogonal contrasts exhibited a weak correlation between OPF and the aforementioned parameters ( r 2 = 0.11, p = 0.040; r 2 = 0.11, p = 0.042 respectively). Indeed, these findings are in agreement with the other growth performance parameters, which did not show significant differences, and also with other studies evaluating orange peel in broiler diets (Akbarian et al, ; Alzawqari et al, ).…”

The effects of dietary vitamin C and Citrus Sinensis peel on growth, hematological characteristics, immune competence, and carcass characteristics in broilers exposed to heat stress

“…These results are comparable with those reported by other researchers (22,23). Furthermore, (28,29) evinced a no significant effect in the mean body weight at starter period of age in the broiler chickens receiving Sop in their diet (0.4 or 0.8 g/kg feed) as compared with control group. The no significant effect of orange peel powder on growth performances in the 35-day of rearing period is unknown.…”

The effect of phytogenics on growth traits, blood biochemical and intestinal histology in broiler chickens exposed to Clostridium perfringens challenge

“…In addition, the intestinal weight was higher in infected and infected + supplemented groups. The higher intestinal weight in these groups may be due to the inflammation and accumulation of the exudates in the intestines of these infected groups (Abudabos et al 2016;Alzawqari et al 2016).…”
