Resumo: |
Panax ginseng, a medicinal plant known as the plant that "cure all ills" is indicated as adaptogenic, immune stimulant, restorative physical and mental health, increased resistance to exogenous stress factors, among others. The aim of this study was to evaluate the action of a commercial Panax ginseng product on performance, egg quality, biochemical, hematological, immunological and behavioral profile of hens during initial hen s laying cycle 1. The experimental design was completely randomized with five treatments which consisted in different levels of Panax ginseng (T1 control (without Panax ginseng); T2 1.9; T3 3.8; T4 5.7 and T5 7.6 mg/hen/day) in a total of 70 birds housed in 35 cages with seven replicates per treatment. The basal diets were prepared using corn and soybean meal in agreement with the nutritional values established by the breeder manual. To predict the effect of different levels of Panax ginseng on performance, egg quality, biochemical, hematological, and immunological traits the regression analysis was used. The Dunnett test was used in each Panax ginseng levels to compare to the control treatment. Ethological parameters were evaluated using chi-square analysis. Performance and egg quality were not influenced by dietary treatments, except specific gravity in the first period that was lower in 5.7 mg/hen/day levels and the eggshell weight that was higher in 7.6 mg/hen/day level in comparison with the control treatment in the fourth period. In sensorial analysis, egg yolk color alteration, but not flavor, texture and taste was observed after 30 days of utilization of Panax ginseng. No significant difference was found in hen s hematological profile in all periods evaluated. In metabolic parameters, higher level of phosphorus in hens receiving 7.6 mg/hen/day of Panax ginseng at second and third period and albumin was observed only in the last period when compared to the control group. Cholesterol level was higher in hens receiving 1.9 and 3.8 mg/hen/day of Panax ginseng in comparison with the control treatment. No significant difference among treatments was found in antibody titer after vaccination. In ethological parameters vigilant behavior was more frequent in control group, preening in the group receiving 7.6 mg/hen/day and drinking in the intermediate levels of Panax ginseng (3.8 and 5.6 mg/hen/day). The supplementation with Panax ginseng up to 7.6 mg/hen/day do not change the performance, egg quality, hematological profile and immunological status. Only small variations in the metabolic parameters and behavior frequency of the hens receiving Panax ginseng could be expected. |
