This study was designed to investigate the effects of dietary fenugreek seed extract (FSE) supplementation on egg production, egg quality, blood profiles, cecal microflora, and excreta noxious gas emission in laying hens. A total of 384 laying hens (26-weeks old, Hyline-brown) were fed three different levels of FSE (0, 0.05, and 0.1%) in a cornsoybean diet for 6 weeks. The inclusion of FSE in the laying hen diet did not affect egg production, feed intake, or feed conversion among treatments; however, egg weight, eggshell breaking strength, eggshell thickness, and yolk color increased in FSE-fed groups (linear, P<0.05). Supplemental FSE decreased the serum total cholesterol concentration, whereas the HDL-cholesterol concentration increased in the FSE fed-groups (linear, P<0.05). FSE led to an increase in cecal Lactobacillus number (linear, P<0.05), and a decrease in Escherichia coli number (quadratic, P<0.05) and excreta ammonia gas emission (linear, P<0.05). These results suggest that the addition of FSE does not increase egg production, but may affect egg quality, serum total- and HDL-cholesterol concentration, and cecal microflora. FSE also decreased ammonia gas emission in laying hen excreta.

It is currently accepted that the consumption of fruit-derived antioxidants such as vitamin C, carotenoids, and flavonoids provides a preventive effect against cardiovascular disease. The purpose of the present study was to investigate potential cardiovascular protective properties of aqueous and 70% ethanol extracts from kiwifruit by analyzing the antioxidative, antihypertensive, hypocholesterolemic, and fibrinolytic activities in vitro. Aqueous and 70% ethanol extracts at 50 mg/ml showed DPPH-radical scavenging activities of 72.31% and 70.75%, respectively. Total antioxidant activity in linoleic acid emulsion was 85—88% at 10 mg/ml and 96—98% at 50 mg/ml of kiwifruit extract. Inhibitory activities against angiogensin I-converting enzyme of kiwifruit extracts were 21—26% at 10 mg/ml and 46—49% at 50 mg/ml, and inhibitory activities on HMG-CoA reductase were 13—14% at 10 mg/ml and 19—30% at 50 mg/ml. Fibrinolytic activity of kiwifruit was also observed at a high concentration of 100 mg/ml in both aqueous and 70% EtOH extracts. Based on our results, kiwifruit have potential cardiovascular protective properties in vitro.
