Effect of ginger and L-carnitine on some reproductive parameters of male rats

This study was performed to evaluate the effect of ginger and L-carnitine on the effect of ginger and L-carnitine on reproductive performance of male rats including semen evaluation [count, motility and viability of sperm], male sex hormones [Testosterone, FSH and LH] and testicular antioxidant system [reduced glutathione, catalase, and superoxide dismutase and total antioxidant capacity]. The study was carried out on sixty mature male albino rats divided into four groups [fifteen rats each]. One group received physiological saline and kept as a control, while rats of the other three groups received ginger [100mg/kg/day], L-carnitine [150mg/kg/day] and combination of both ginger [100mg/kg/day] and L-carnitine [150mg/kg/day] respectively by stomach tube daily for one month. After the end of treatment period, rats were sacrificed with evaluation of semen and determination of antioxidant enzymes and sex hormones. Results showed that the three previous treatments improve sperm parameters, antioxidant enzymes and testosterone hormone with more favorable and pronounced effects in the group that received combination of both ginger and L-carnitine. Therefore, this study recommends that administration of a combination of ginger and L-carnitine may be beneficial for improving male sexual performance

Biochemical effect of some feed additives and immunological response in broilder chickens

This study was investigated the effects of dietary supplementation with prebiotics beta-glucan, MOS 500 and Bio MOS [registered sign] on the broilers performance, biochemical parameters and immune response for 5 weeks. One hundred and twenty 1-day-old broiler chickens were randomly assigned to 4 dietary treatment groups as follows: control, beta-glucan [1g/kg], MOS 500 [0.5g/kg] and Bio MOS [registered sign] [1g/kg]. Each treatment was divided into three replicates [ten birds/ replicate]. The overall BW gains of birds treated with prebiotics were significantly [P <0.01] higher than those of the control group. During the experiment, the birds fed supplemental Bio MOS [registered sign] gave the best FCR followed by beta-glucan MOS 500 and then the control group. Addition of these prebiotics were improved the levels of serum total protein and globulin which in turn support the immune function against NDV and IBDV. In addition to, supplementation of broiler chicks by beta-glucan, MOS 500 and Bio-MOS [registered sign] had no effect on the liver transmination enzymes and some kidney function which represent the non pathological metabolism of the liver and kidneys indicating their safety supplementation in broiler feed
