| Popis: | SUMMARY Tribulus terrestris is (TT) is a source for industrial production of medicinal preparations based on its saponin fraction. This plant is extremely rich in substances having potential biological activity, such as saponins, flavonids, alkaloids, glycosides, phytosteroids, and other constituents such as tannins, which influence gastrointestinal microflora and exert astringent effects due to their antibacterial properties. The steroidal saponins, such as dioscin, diosgenin, and protodioscin, are behind the plant's well-known beneficial effects on increasing sex hormones, leading to an increase in reproductive performances. The objective of the present study was to investigate the effects of adding aqueous extract and dried aerial part powder of TT on performance and blood parameters of hens during the laying period (28 to 40 wk of age). A total of 210 Hy-Line W-36 were randomly assigned to 5 treatments, with 6 replicates of 7 hens each. The experiment was a completely randomized design with 5 levels of TT, including zero (T1), 5 mg (A5), or 10 mg/kg BW (A10) aqueous extract added to drinking water and 5 mg (F5) or 10 mg (F10) aerial part powder per kilogram BW added to the feed of laying hens. The results indicated that daily feed intake decreased (P 0.05) on egg and yolk index or Haugh unit. Shell thickness and weight were increased (P |
