Abstract

The present study was designed to investigate the effect of curcumin and anise ground seeds levels as well as their interactions on growth performance and some carcass traits of Ross308 broiler chickens. Two hundred and ninety seven birds were randomly assigned in (3×3) factorial design experiment. Three curcumin levels (0 ,50,100 mg/kg in diet) and three anise ground seeds levels (0 ,0.50% and 1% in diet) were used in nine treatments of 33 birds each (three replicates of 11 birds each).The body weight and feed intake were measured weekly and consequently, weight gain and feed conversion ratio were calculated. At the end of the experiment, three birds from each group were sacrificed to evaluate carcass parts. The results showed that chickens fed curcumin at level of 100 mg/kg diet achieved significantly higher body weight at 14 days of age and body weight gain during the period of 7-14 days than control. The addition of anise ground seeds at level of 1% achieved higher feed intake than control. The addition of 50 mg/kg diet of curcumin and 1% anise ground seeds achieved better feed consumption during the period from 14-21 and 21-28 days of age than other interactions. No significant (P>0.05) effects on feed conversion ratio due to curcumin, anise ground seeds and their interactions were obtained. There were significant (P<0.05) effect due to curcumin levels on hart and left femur. Also, There were significant (P<0.05) effect due to anise seeds on shank , tibia left and neck. No significant (P>0.05) effect due to either curcumin or anise ground seeds or their interactions were observed on carcass and dressed percentages.It was recommended that curcumin may be added at level of 100 or 50 mg/kg diet, or 50 mg/kg of curcumin plus 1% anise ground seeds to achieve higher growth performance and carcass criteria of broiler chicken (Ross 308).

The Productive Performance, Immunological Parameters and the Bioavailability of Calcium, Phosphorus and Nitrogen of Japanese Quails Fed Curcumin and/or Ground Anise Seeds Supplementation as a Medical Herbs

“…Under these circumstances, the use of phytochemicals in poultry feed has been closely monitored. Recently, it is important to investigate the plant material effects such as curcumin and ground anise seeds in terms of performance, immune functions and nutrients availability as the specified criteria (Metwally et al, 2021), because it is well documented that some plant extracts can affect the secretion of digestive enzymes and act as antibacterial, anti-viral, and antioxidizing agents (Ertas et al, 2005;Cross et al, 2007). To date, due to the limitations of the use of antibiotics, the use of natural alternatives such as medicinal plants has been considered.…”

Influence of Curcumin and Ground Anise Seeds as Medical Herbs on the Performance, European Production Efficiency Factor, Carcass Characteristics and Some Blood Constituents of Japanese Quails

“…Therefore, today, due to the limitations of the use of antibiotics, the use of natural alternatives such as medicinal plants have been considered. Medicinal plants as a natural feed additive used as growth promoters and flavor agents, may be used an alternative to antibiotics, and improve the live performance and the immune response, maintaining bird health, and reducing the effects of oxidative spoilage such as curcumin (Metwally et al, 2021), cinnamon, pepper, sage, thyme, and rosemary (Hernandez et al, 2004) or anise powder (Metwally et al, 2021) in broiler feeds. Turmeric (curcuma longa) is one of the many medicinal herbs used in poultry diets (Laguma and Ampode, 2021).…”
