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.
