In this study, the effect of adding a mixture of medicinal plants to the diet of lactating ewes on growth performance and antioxidant properties of suckling female lambs was investigated. Twenty-four lactating Roman ewes at first lambing along with 24 female lambs of three to five days old weighing 3.17 ± 0.15 kg were kept in individual pens for 65 days in a completely randomized design. Experimental groups of ewes included: 1-control (basal diet), 2-basal diet + 15g of herbal powder including 60% cumin, 30% coriander and 10% peppermint, 3-basal diet + 15g of herbal powder including 45% cumin, 45% coriander and 10% peppermint and 4-basal diet + 15g of herbal powder including 30% cumin, 60% coriander and 10% peppermint. Lambs were weighed every two weeks and, blood was taken from the lamb's jugular vein at the end of experiment. The final weight (21.64 vs. 16.89 kg) and ADG (276.67 vs. 211 g) of lambs in second treatment were higher (P<0.05) than the control. The RDW in the second and third treatments was lower than that of control. The blood total antioxidant capacity of lambs in the second treatment was higher (P<0.05) than control (0.09 vs. 0.04 mmol/l). Incorporation a mixture of cumin, coriander and peppermint in proportions of 60, 30 and 10%, respectively, to the diet of lactating ewes improved the ADG and blood total antioxidant capacity of female suckling lambs, and no adverse effects were observed on hematology and blood parameters

This study was done to investigate the effect of pomegranate peel extract on growth performance, blood biochemical indices, intestinal morphology and meat quality of broiler fed diet-contained soybean oil. 120 male broilers were used in the form of a completely randomized design with 3 treatments, 4 repetitions and 10 chicks. Experimental diets were three levels of zero, 300 and 600 mg/kg of pomegranate peel extract (PPE). Pomegranate peel extract had no effect on performance traits including feed intake, body weight and feed conversion ratio at starter and finisher phases, but in the grower period, the levels of 300 and 600 PPE reduced feed intake (from 928 to 777 g) and feed conversion ratio (from 1.77 to 1.31; P <0.05) compare to control. The breast percentage increased from 19.78 in control to 21.95 at the level of 600 PPE and the percentage of abdominal fat decreased from 1.93 in control to 1.27 at the level of 600 PPE (P <0.05). The PPE at levels of 600 reduced concentration of cholesterol (183.68 to 137.15 mg/dl) and LDL (95.63 to 32.93 mg/dl) and the enzyme activity of aspartate dehydrogenase (263.8 to 204.28) compare to control. The villus height (from 1026.88 to 1155.12) and the villus height to crypt depth ratio (5.04 to 5.6) were higher at the 600 PPE compared to the control. The concentration of Malondialdehyde in meat decreased at 15 and 30 days after slaughter with an increase in PPE compared to control.

Many of blood serum biochemical parameters are associated with resistance to disease, meat quality and performance traits, and can be useful in determining animal health status. The aim of this study was to investigate the effect of strain and sex on growth traits and blood serum biochemical parameters of quail. For this purpose, a number of one-day-old chicks from each quail strain (125 Wild, 159 Italian speckled, 58 Scarlet, 56 Tuxedo, 81 English white, 92 A and M Texas and 57 White Button), were used. The chicks were weighed weekly until 42 day of age. At 35 day of age, 10 birds (5 male and 5 female) were slaughtered from each strain, and their blood serum was separated. The evaluation of blood serum biochemical parameters including total protein, albumin, globulin, glucose, cholesterol, triglyceride, uric acid, calcium, phosphorus, aspartate aminotransferase (AST) and alkaline phosphatase (ALP) enzymes parameters was conducted using autoanalyzer apparatus. The growth traits and blood serum biochemical parameters data were analyzed and compared with R comuter software among strains and sex levels. The effect of sex on body weight at 42 day of age, body weight gain in sixth weeks, calcium, globulin and AST enzyme was significant and strain had a significant effect on all growth traits, cholesterol, triglyceride and phosphorus (P <0.05). All growth traits and blood serum biochemical parameters (with the exception of uric acid and AST enzyme concentrations) were higher in female quails than those of males.
