Objectives: Hypericum perforatum L. is a medicinal plant containing many polyphenolic compounds, ‎including flavonoids and phenolic acids with antidepressant and anti-inflammatory properties. ‎This study was investigated the effects of Hypericum perforatum extract (HPE) on immunity, ‎body weight (BW), and spleen index (SI) in rats.

Effects of saffron (Crocus sativus) petal ethanolic extract on hematology, antibody response, and spleen histology in rats.

Objective: Saffron petal is a by-product that contains flavonoids and anthocyanins. In order to study the effects of saffron petal extract (SPE) on blood parameters, immune system, and spleen histology, five treatments (n=6) were used in a completely randomized design.

Materials And Methods: The treatments were 0, 75, 150, 225, and 450 mg/kg body weight of SPE.

Quality of bovine chilled or frozen-thawed semen after addition of omega-3 Fatty acids supplementation to extender.

Background: This study was conducted to evaluate the potential protective effects of omega-3 poly unsaturated fatty acids (Ω-3 PUFAs) on bovine sperm quality in response to cooling and cryopreservation.

Materials And Methods: : In this experimental study included ejaculates from five proven fertile bulls, allocated to the control and the four experimental groups. For group 1, polyethylene glycol (PEG) as a solvent was added alone to the extender, while for groups 2, 3 and 4, different concentration of omega-3 PUFAs (1, 2.

Effects of chicory root powder on growth performance and histomorphometry of jejunum in broiler chicks.

In the present study, chicory root powder (CRP) as growth promoter at 1% and 3% levels was supplemented in broilers' diet to investigate the growth performance and histomorphometry of jejunum. One hundred twenty, one-day-old male broilers were used in a completely randomized design (CRD) with 3 treatments and 4 replicates (10 chicks per replicate). At the end of each period (0-10, 11-24 and 0-24 days), feed intake (FI), weight gain (WG), and feed conversion ratio (FCR) were measured.

Hypolipidemic and antioxidative effects of curcumin on blood parameters, humoral immunity, and jejunum histology in Hy-line hens.

Objective: Turmeric (Curcuma Longa Linn) is a medicinal plant that contains curcumin. There is a growing interest in using curcumin powder (CP) as feed additives for antioxidative and antimicrobial properties to improve human health. This study was conducted to determine the appropriate levels of CP on blood parameters, immunity, and histology of jejunum in hens.
