The present study was carried out to determine the effects of fenugreek powder (FP) and extract (FE) on performance, egg quality, blood parameters and immune responses of laying hens. One-hundred and fifty Leghorn laying hens were used in a completely randomized design with five treatments and five replicates for eight weeks. Treatments were various levels of FP and FE including zero (control; T1), 1.00% FP (T2), 2.00% FP (T3), 0.10% FE (T4) and 0.20% FE (T5). The results of this experiment showed that feed intake was increased linearly by the inclusion of FP compared to the control group. Supplementation of laying hens diet with 2.00% FP adversely affected feed conversion ratio (FCR). The FCR was decreased by 0.10% inclusion of FE compared to 0.20%. Egg yolk color was the highest when 1.00% FP added to laying hens diets compared to the other treatments. Serum metabolites and immune responses of laying hens were not affected significantly by fenugreek supplementation. From the results of the present study, it can be concluded that using 1.00% FP can improve feed intake by supporting FCR. Inclusion of 1.00% FP in laying hens diet enhanced egg yolk color of laying hens in the second production cycle.Most aspects of reproductive function including spermatogenesis, oocyte growth and maturation, early embryonic development, fetal and placental growth, and lactation can be affected by thermal stress. Furthermore, it has been shown that oxidative stress involves in the pathology of thermal stress. Therefore, the aim of this study was to investigate the impacts of thermal stress on the ovine mature epididymal spermatozoa extracted from testes of slaughtered rams in the presence or absence of an antioxidant. Epididymal spermatozoa were incubated at scrotal (32.00 ˚C), normal body (39.00 ˚C), and hyperthermic temperatures (41.00 ˚C) for 4 hr in the presence or absence of 1 mmol L-1 β-mercaptoethanol. The results demonstrated the high sensitivity of ram epididymal spermatozoa to the hyperthermic temperature at in vitro conditions. In comparison with scrotal temperature, quality parameters of spermatozoa were negatively affected by increase in temperature, as such in the spermatozoa incubated at hyperthermic temperature significant decrease was observed in the viability, DNA integrity and in the majority of motility parameters. Moreover, concentration of lipid peroxidation by-products, thiobarbituric acid reactive substances, were significantly increased. The findings showed that using antioxidant during incubation period had significant protective effect on the viability and motility of incubated spermatozoa not only at the hyperthermic temperature, but also at the scrotal and normal body temperatures. In conclusion the ovine epididymal spermatozoa were sensitive to in vitro thermal stress and it seems that this sensitivity was partly related to the oxidative stress.Fluoxetine is a selective serotonin reuptake inhibitor is commonly prescribed to treat maternal depression in pregnancy and lactation. This study aimed to investigate the effects of maternal exposure to fluoxetine via lactation on testicular tissue, sperm parameters including count, motility, viability, and normal morphology and testicular oxidative stress status in male mice offspring. Ten mice dams were divided into control and experimental groups. The control group received water and the experimental group received fluoxetine (20.00 mg kg-1) by gavage daily from postnatal days of 0-21. Histology of testis, sperm parameters and oxidative stress in the testicular tissue were analyzed at 80 days after birth in their male offspring (n = 8). Significant reductions in the body and testes weights were observed in animals exposed to fluoxetine. Additionally, fluoxetine exposure significantly reduced all sperm parameters, tubular diameter and epithelial height of the seminiferous tubules as well as Leydig cells number. Significant increases in the testicular malondialdehyde levels and percentage of sperm with chromatin/DNA damage were observed in mice exposed to fluoxetine compared to control. These findings suggest that maternal exposure to fluoxetine during lactation in mice has a negative effect on the testicular tissue of their offspring and impairs the spermatogenesis process which in turn can induce infertility.The present study was aimed to determine the protective effects of Plantago major L (PM) leaf extracts on the testicular torsion/detorsion (T/D)-induced ischemia/reperfusion (I/R) injury in rats. Twenty-four mature male Sprague-Dawley rats, weighing 200-220 g, were selected. They were randomly divided into four groups of six animals each Sham (sham-operated rats; all the surgical steps were performed but T/D was not induced), TDC (Control group; T/D was induced and the right testicular torsion of 720° lasting two hours was followed by detorsion), TDP50 (T/D-operated rats received 50.00 mg kg-1 of PM extract daily for seven days intraperitoneally after detorsion) and TDP100 (T/D-operated rats received 100 mg kg-1 of PM extract daily for seven days intraperitoneally after detorsion). After seven days of treatment, the right testicles were collected. Histopathological and biochemical analyses including levels of malondialdehyde (MDA) and catalase (CAT) and peroxidase activities were determined in testicular tissues of the rats. Favipiravir molecular weight Tissue sections were taken from testis, Hematoxylin-Eosin staining was done, and the slides were examined by a light microscope. The level of MDA was significantly increased in the testes of the TDC group. The CAT activity levels were decreased significantly after I/R. The post-torsion treatment with PM, particularly at 100 mg kg-1, prevented the increase in lipid peroxidation and reduced the CAT activity levels. The PM also prevented I/R-induced cellular damage and histological changes in the testicular tissues. According to the results of the current study, PM leaf extracts had significant positive effects on the testicular T/D-induced I/R injury. The possible mechanism of reduction in biochemical and histological injuries by PM extracts could be due to antioxidant property.
