Henna (Lawsonia inermis L.) leaves have unique medicinal properties like antibiotic ones due to the large amounts of phenolics such as tannins. To investigate the effects of feeding with henna leaves on performance, some blood parameters, and liver enzymes of 20 Kermani male lambs, an experiment was conducted in a completely randomized design with five replications. Experimental treatments included (T1) basic diet (BD) (control), (T2) BD+30 g henna leaves (HL), (T3) BD+60 g HL, and (T4) BD+90 g HL. The results showed that although the treatments did not have significant effects on performance, but the highest and lowest amount of feed consumption and food conversion ratio were respectively observed in control and T4, as well as the highest and lowest amount of daily weight gain belonged to T4 and control, respectively. Glucose and blood urea nitrogen concentrations were not affected by the experimental treatments (P≥0.05). Cholesterol, triglyceride, and total protein concentrations were significantly increased with increasing henna leaf amount in the diet (P≤0.05). The lowest concentrations of liver enzymes aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were obtained in T3 (P≤ 0.05). Overall, it was revealed that using different levels of henna in the diet of Kermani lambs did not affect their growth performance and glucose, but significantly increased cholesterol, triglycerides, and total protein and decreased AST and ALT.

To evaluate the effects of a mixture from Cinnamomum cassia (L.) J.Presl, Mentha pulegium L., and Capsicum annuum L. extracts on the relative weight of visceral and gastrointestinal organs, gastrointestinal tract acidity, blood parameters, and tibia characteristics of Ross 308 broilers, an experiment was conducted in a completely randomized design with five treatments, four replications, and eight chickens per replication. The experimental treatments included basal diet (BD), BD+500 mg kg-1 oxytetracycline, BD+50 mg kg-1 mixed extract, BD+100 mg kg-1 mixed extract, and BD+200 mg kg-1 mixed extract. After 42 days of raising the broilers with the mixed extract, the sampling was performed to evaluate the desired traits. The results showed that the consumption of 100 mg kg-1 mixed extract increased the pancreas and heart weight, relative length of ileum and jejunum, and relative weight and length of tibia and reduced the acidity of duodenum and jejunum compared to the control (p < /em><0.05). The results showed that the experimental treatments did not affect the concentration of blood elements of broilers, but the amount of magnesium and phosphorus in tibia was affected by 50 and 100 mg kg-1 mixed extract (p < /em><0.05). Based on the findings of this study, it could be concluded that the use of 100 mg kg-1 mixed extract improved the performance of broilers by increasing the relative length and weight of gastrointestinal organs and reducing the acidity of gastrointestinal tract.

Because of the use of phenol in petrochemical industry and as a disinfectant effect in medicine, this material is widely used. However, the free phenol in the environment is detrimental to the health. The aim of present study was to evaluate the protective effect of Hypericum perforatum L. on some of the blood biochemical parameters in rats with toxicity induced by phenol. For this purpose, a number of 54 male Wistar rats were divided into 9 treatment groups as 3×3 factorial design with two main factors of Hypericum perforatum (at concentrations of 0, 250 and 500 mg/kg.bw) and phenol (at concentrations of 0, 100 and 200mg/kg.bw). Rats received the extract and phenol every other day with gavage method. On days 15 and 30 of experiment, after blood sampling, the concentrations of some blood serum biochemical parameters were evaluated. In first half of experiment, 200 mg/kg.bw of phenol significantly increased the blood serum cholesterol and LDL values and a concentration of 100mg/kg.bw reduced the VLDL level (p<0.05). In second half of experiment, the highest level of HDL was observed in treatment 250 and 200 mg/kg.bw Hypericum perforatum and phenol, respectively and its lowest value was recorded at concentrations of 500 and 200 mg/kg.bw Hypericum perforatum and phenol, respectively (p<0.05). The other main and interaction effects of treatments were not significant (p>0.05). The findings of present research show that the extract at a concentration of 250 mg/kg could decrease the adverse effect of phenol on HDL biochemical parameter in the long term.

Licorice with common name of licorice pea from Leguminosae family has been noted for its many therapeutic effects. Using natural substances of plant origin has a long history in the treatment of various diseases. In this research, the effect of licorice on blood factors was examined. This study was performed on 50 mice. The samples were randomly divided into five groups (three treatment groups, control and the placebo group) and were kept under identical conditions. Hydro-alcoholic extracts of Licorice in doses of 50, 100, 150 mg/kg were injected by intraperitoneal (IP) within 20 days every other day. Physiological serum was injected to the control group. The main parameters included the RBC count, hemoglobin, hematocrit, platelet count, MCHC, MCH and MCV compared with control groups. Results showed that hemoglobin, platelet count, MCV and MCHC increased at all doses and MCH increased in 100 and 150 mg/kg dose, but the number of red blood cells decreased in doses of 100 and 150 mg/kg. No significant changes were observed in hematocrit. Results indicated a dose-dependent effect of the licorice on blood factors in mice.

This experiment was conducted to evaluate the effects of Satureja hortensis L., Ziziphora tenuir L., Urtica dioica L. and their different mixtures on yield, egg quality, blood and immunity parameters of laying hens. A 23 factorial experimental design was applied with 8 treatments in 1- control treatment or no medical plants, 2- 2% of S. hortensis, 3- 2% of Z. tenuir, 4- 2% of U. dioica, 5- 2% of (S. hortensis and Z. tenuir), 6- 2% of (S. hortensis and U. dioica), 7- 2% of (Z. tenuir and U. dioica) and 8- 2% of (S. hortensis, Z. tenuir and U. dioica) including 3 replicates in each treatment and 12 hens in each replicate for 12 weeks )25-37 weeks of laying period). The results showed that the use of different medicinal plant mixtures had significant effects on yield, and egg quality of laying hens (P<0.05). Maximum egg yield (86.622%) and egg mass (47.497 g) were recorded for 2% of U. dioica treatment whereas the maximum eggshell weight (5.804g) and unit (94.635%) were obtained by using 2% of S. hortensis. Using 2% of U. dioica also had positive effects on blood biochemical parameters and percentage of immunity cells. According to the results, using 2% of U. dioica in laying hens' diet could have positive effects on their yield, blood biochemical parameters and percentage of immunity cells.
