This experiment was performed to investigate the effects of probiotic on productive traits, blood parameters, serum lipoproteins, and blood immune response of broilers fed with pumpkin seed oil. A total of 480 one-day-old Arian commercial broilers in a 2×3 factorial experiment, with two plant oil sources (canola and pumpkin) and three additives (no additive, probiotic and antibiotic) in a completely randomized design with four replicates and 20 chicks per replicate, were randomly distributed among the experimental units. The results showed that probiotic application with plant oil sources had no negative effect on productive traits including relative weight of carcass, breast, thigh, abdominal fat, survival percentage, and feed conversion ratio. The percentage of blood hematocrit in the chicks receiving the additives was lower than the control group (P<0.05). The effect of oil source and additives on other blood parameters including total protein, glucose, and uric acid was not statistically significant. The use of pumpkin (Cucurbita pepo L. convar. pepo var. styriaca) seed oil significantly reduced triglyceride and very-low-density lipoprotein (VLDL), and increased total cholesterol and high-density lipoprotein (HDL) (P<0.05). The effect of oil source on low-density lipoprotein (LDL) was not statistically significant. The lowest levels of triglyceride, total cholesterol, HDL, and VLDL were observed in chicks fed with pumpkin seed oil and virginamycin (P<0.05). The highest amount of triglyceride was observed in chicks fed with canola oil and antibiotics (P<0.05). The effect of oil source and additives on blood immune response and relative weight of lymphoid organs was not statistically significant. Generally, using pumpkin seed oil resulted in a partial improvement in serum lipoproteins. On the other hand, the efficiency of the additives depended on the type of oil (fatty acid profile) used in the diet.

An experiment was conducted to determine the effect of supplementation of butyric acid and Aloe vera L. on performance, intestinal morphology, blood factors and egg quality in laying Japanese quail. Total of 120 layer quails were randomly assigned to six experimental treatments and five replicates, each with four birds in a completely randomized design for seven weeks. Experimental groups were: 1- control basal diet (Without organic acid and Aloe vera supplements) 2- basal diet+Aloe vera (1%) 3- basal diet +sodium butyrate (500ppm) 4-basal diet+butyric acid glycerides-Baby C4 (500ppm) 5- basal diet +Aloe vera (1%)+sodium butyrate (500) 6- basal diet+Aloe vera (1%)+butyric acid glycerides (500ppm). In this experiment, egg production ratio, feed intake, feed conversion and egg weight were not affected by the treatments. All treatments lowered the cholesterol contents of serum and yolk compared to control group (p<0.01). Treatments significantly influenced jejunum villi (p<0.001). The use of Aloe vera alone and combination of Aloe vera andsodium butyrate or butyric acid glycerides produced eggs with reduced cholesterol content. Simultaneous use of Aleo vera and butyric acid glycerides significantly increased the villi height and surface area and the highest villi width and the deepest villi crypts were observed in this group. In conclusion, supplementation of layer quails’ diets with Aloe vera significantly reduced serum and yolk cholesterol contents, which may confer health benefits to consumers.

The effects of three herbal plant powders (thyme, cinnamon and turmeric) on growth performance and ascites were studied in broilers. Eight hundred one-day-old Arian broiler chicks were randomly allocated into eight treatment groups with four replications and 25 chicks per cage. The experiment lasted for 42 days. Energy and high protein diets were used to increase the speed of growth and inducing ascites in broiler chickens. Experimental treatment groups were: control treatments, consisting of two diets with different nutrient densities (high density and low density) and two base diets were supplemented with herbal powders at a rate of 5 g/Kg of the diet in a factorial arrangement. Feed intake, BW gain and feed conversion ratio of the broilers were measured. Parameters related to ascites (thyroid hormones, hematocrit value, erythrocyte osmotic fragility and right ventricle-to-total ventricle ratio (RV/TV) were measured. Results showed that there were no influences on broilers’ growth performance. On the other hand, hematocrit value, T4, T3/T4 and RV/TV were significantly decreased by using herbal plants compared with the control, but no significant changes were observed on erythrocyte osmotic fragility (EOF) among the treatments. The results of this study suggested that herbal plants have beneficial effects in reducing ascites in broilers.

This experiment was designed to study the effects of feeding diets containing different levels of yucca extract and antibiotic on growth performance, blood parameters, immune system and ascites index. Three hundred and twelve, one-day old broiler chicks (Arian) were used in a completely randomized design with four treatments, consisting of three replications and 26 (male & female) chicks per pen. The treatments consisted of control (without supplementation), Yucca schidigera extract at 150 and 225 mg/kg, and virginiamycin at 15 mg/kg up to six weeks of age. Significant differences were found for feed intake, feed efficiency, and body weight gain in the studied treatments (p < 0.01). Immune responses, expressed as a primary and secondary antibody response to SRBC, were affected by treatments (p < 0.01). Treatment groups did not affect the weights of organs (p < 0.05). Effects of treatments on cholesterol, triglycerides, HDL and LDL levels, at 35 days of age, were significant on the parameters evaluated in different experimental groups (p < 0.01). The trends observed indicate that Yucca schidigera extract could have beneficial effects on broiler chicks performance.

The present experiment was carried out to determine the effects of barley-based diet supplied with probiotic, medicinal plant and antibiotic on performance, blood factor, and broiler's SRBC criteria as means to assess immune response. Three hundred and twenty day-old male broiler chicks were allocated to a randomized complete blocks design with 4 treatments consisting of 4 replications for 42 days. Experiment treatments were included: 1) basal diet with 20% barley (barley control), 2) barley control + probiotic Galpro, 3) barley control + medicinal plant Antibiophen, and 4) barley control + antibiotic virginiamycin. In addition, basal diet supplemented with commercial enzyme preparation. Body weight (BW), feed intake (FI), feed conversion ratio (FCR), blood cholesterol and triglyceride and SRBC, as criteria of immune system response were the measured parameters. Analysis of the experiment showed significant differences within treatments for 42 day-old body weight, as antibiotic treatment had the highest BW and control barely showed the lowest BW. Among treatments, significant differences were found in FCR for the whole duration of the experiment (P<0.05). Not significant differences in FI were noted among treatments during experiment. The FCR was highest in the barley plus enzyme group, but not much different for other treatment groups. Stimulating of immunity system was determined with sheep erythrocytes in two stages. Antibody titer against sheep erythrocytes in groups fed with probiotic and medicinal plant were more than other groups (P<0.05). Cholestrol and triglyceride levels of serume were affected by treatments; medicinal plants had resulted to lowest cholesterol level and antibiotic caused highest triglyceride level. It could be concluded that diet supplementation of broiler chicken with medicinal plant and probiotic as compared with antibiotic offset the negative effect of barley inclusion.

The aim of this study was to determine the effect of dietary extract of thyme and peppermint and vitamin E on layer immunie system and performance in heat stress condition and content of peroxidation egg during storage. One hundred fourty-four Lohmann strain light hens (26 weeks) allocated to four treatments with 3 replications and 6 birds in each replication. Experiment treatments applied included control, thyme, peppermint and vitamin E (200 PPM)) that were hold in two different house temperature (normal and cyclic temperature). Plant extract administrated via drinking water were 1% for normal and 0.6% for warm house. Malondialdehyde (MDA) was determined in fresh and stored eggs for 14 days at different holding temperature (4*c and 23-27*c). Prior to and 14 days after vaccination against Newcastle disease (Lasota) blood samples were collected to evaluate the birds immune responses. To determinate of effects of factors against sheep red blood cell (SRBC) at 42nd and 47th days of experiment antigen were injected. Vitamin E induced antibody against Newcastle vaccination in layers kept at normal temperature (P0.05). Produced antibody amount was increased against NV after vaccination (P>0.05). Antibody titration was not affected by house temperature. Experiment treatment depressed egg MDA (P<0.05). MDA level in fresh egg yolk and those hold at 4*c were reduced by vitamin E, mint and thyme to the extend that in vitamine E group was lowest of all
