he present study was designed to investigate the effect of curcumin, anise seeds levels and their interactions on growth performance European Production Efficiency Factor, carcass criteria and some blood parameters of quails. One hundred sixty-two, one day old of Japanese quails were randomly assigned in (3×2) factorial design. Three curcumin levels (0, 100, 200 mg/kg) and two ground anise seeds levels (0, 1%) in six treatments of 27 chicks each (three replicates of 9 chicks, each) were used. Body weight and feed intake were recorded weekly. Body weight gain and feed conversion were calculated at the end of the experiment (42 day of age). Carcass criteria and some blood constituents were measured throughout the experiment. The results showed the main effect of curcumin didn't affect body weight, body weight gain, feed conversion ratio, European Production Efficiency Factor and European Broiler Index. Numerically, all the previous parameters were improved by supplementation of curcumin or ground anise seeds. Concerning with the interactions between the two medical herbs, the results showed that quails fed curcumin at level of 200 mg/kg plus 1% ground anise seeds diet achieved significantly (P<0.05) higher body weight, body weight gain and feed intake during the period from 0-14 days of age compared to the control. From the current experimental results, we can recommend supplementing diets with curcumin at level of 200 mg/kg and ground anise seeds at level of 1% to improve growth performance.
This study aimed to investigate the effect of curcumin and/or anise seeds supplementation on the performance, immunological parameters and the bioavailability of calcium, phosphorus and nitrogen of Japanese quail fed graded levels of curcumin (0, 100 and 200 mg/kg feed) and ground anise seeds (0, 1%) during a 42-day feeding trial. 162 (one hundred sixty two), one-day-old quail chicks were assigned in factorial design (3×2). The results clearly that curcumin or anise seeds did not have a significant effect on body weight (BW) and body weight gain (BWG). Anise seeds supplementation improved feed conversion ratio (FCR) during the period from 3-6 wks of age. Quails fed curcumin at level of 200 mg/kg plus 1% ground anise seeds achieved significantly (P<0.05) higher feed conversion ratio (FCR) during the first 3 wks of age. Curcumin groups exhibited highly significant relative weight of spleen and bursa of fabricius , IgA, IgM, and IgG compared to the control group. Birds fed diets containing curcumin at level of 200 mg/kg and 1% anise seeds had numerically higher calcium and nitrogen bioavailability. Phosphorus bioavailability was significantly (P<0.05) higher in birds fed 200 mg/kg curcumin and 1% anise seeds. It was recommended that curcumin should be add at level of 200 mg/kg diet or with 1% anise ground seeds to achieve the best results of growth performance, immunological parameters and the bioavailability of calcium, phosphorus and nitrogen.
Six blends of medicinal herbs were used in Japanese Quail diet to study their effects on performance, plasma lipids, breast meat compassion, tibia bone characteristics and nutrient digestibly in Japanese Quail. One hundred eighty (180, oneday-old) unsexed quail were divided into six dietary treatments including basal diet with no addition of medicinal herbs (T1), basal diet plus 15 g/kg of herbal blends including; cinnamon and thyme powder (T2), rosemary and anise seed powder (T3), caraway and coriander powder (T4), Fenugreek and cumin seed powder (T5) and parsley and watercress powder (T6). The results showed that chicks were fed T6 mixture of parsley and watercress) achieved high % of crude protein in breast meat of Japanese, while ash% was higher in group fed T4 in which fed mixture diets with fenugreek and cumin. The digestibility of nutrients were significantly (P<0.05) enhanced in T6 except ether extract digestibility and ash retention, which were achieved the highest values in T4 (caraway and coriander) compared with the other groups. Supplementing the diets of Japanese quail with mixture of parsley seeds and watercress at level of 15 g/kg of basal diets resulted significant improvement in the performance, plasma lipid triglycerides, cholesterol, HDL, LDL., breast meat protein, , tibia bone characteristics (tibia weight, length, diameter, ash and robusticty index and nutrient digestibility (protein, calcium, phosphorus and nitrogen). T6 in which chicks were fed basal diet supplemented with 1.5% parsley and watercress powder (50%:50%) achieved the highest net revenue compared with the other supplemented treatments.
