The effect of feeding essential oil of Pistacia Atlantica Kurdica gum during the suckling period on pre and post-weaning growth performance of Sanjabi male lambs using 30 male lambs from an estrus synchronized flock of ewes was carried out, in the form of a completely randomized design with 3 treatments and 10 replications. The lambs were divided into three groups three days after birth. The first group received no essential oil, and the second and the third groups received a daily dose of 0.8 and 1.6 ml until weaning by a drenching syringe, respectively. Lambs were weaned at 100 days of age and were raised for 10 weeks with the other herd lambs until 170 days of age. Feeding the essential oil increased weaning weight and post-weaning daily weight gain. The blood glucose of lambs during the suckling or post-waning period did not change due to feeding the essential oil. Lambs received the essential oil and had lower blood cholesterol, triglyceride, total protein, and higher urea and albumin to globulin ratio. Feeding the essential oil reduced blood malondialdehyde levels but increasing the level of the essential oil did not further decrease this metabolite. The results showed that the essential oil as a new feed additive has a good potential to improve the pre and post-weaning performance of lambs when fed during the suckling period. Since, increasing the level of the essential oil resulted in no additional improvement in the performance of lambs therefore, a daily dose of 0.8 ml is recommended.

Abstract
The effect of garden thyme essential oil (TEO) and rapeseed oil (RO) on performance, immune traits and intestinal morphology using 432 one-day-old Ross 308 male broiler as a (3x3) factorial experiment in a completely randomized design including different levels of TEO (0, 300 and 500 ppm) and RO ...

The effect of garden thyme essential oil (TEO) and rapeseed oil (RO) on performance, immune traits and intestinal morphology using 432 one-day-old Ross 308 male broiler as a (3x3) factorial experiment in a completely randomized design including different levels of TEO (0, 300 and 500 ppm) and RO (1, 3 and 5 percentage) were evaluated with 9 treatments and 4 replicates. Throughout the rearing period, broiler chickens receiving 3% gained more weight than 1% of RO and chickens receiving 300 ppm gained more weight than those without TEO (P˂0.05). The use of 3% RO + 300 ppm TEO increased the thigh percentage compared to 1% RO. At 1 and 5 percentage levels of RO, with increasing levels of TEO in the diet, blood cholesterol and LDL concentrations decreased and blood HDL increased (P<0.01). Levels of 3% and 5% of RO + 300 and 500 ppm of TEO in broiler chicken diets increased lymphocyte percentage and antibody titer against Newcastle disease and decreased heterophil percentage and heterophil to lymphocyte ratio of blood (P<0.05). Broiler chickens receiving diet containing TEO had the highest ratio of villi height to crypt depth (P<0.01). Based on the results, the level of 3% rapeseed oil + 300 ppm thyme essential oil in the diet of broiler chickens can be used to improve performance, immunity and biochemical traits of blood.

The aim of this study was to evaluate the effects of different levels of Citrus Limon essential oil on nutrient digestibility, blood and ruminal metabolites in male Holstein calves. This study were conducted using four male Holstein calves, each fitted with a permanent rumen cannula (average body weight 650±20 kg) that received experimental diets including control with 600, 800 and 1000 mg/d lemon essential oil and control with monensin 300 mg/d in a change-over complete randomized block design with five periods of 17 days. Apparent digestibility of OM in ration including of 1000 mg per day of Citrus Limon was highther than the others treatments (P<0.05). Experimental treatments had not affected on DM, CP, EE, NDF and ADF digestibility. The effect of treatments were not significant on glucose, HDL, albumin, total protein, cratinin, and triglyceride and urea concentration, but cholesterol values and BHB concentration in serum of control treatment were more than the other treatments (P<0.05). The concentration of propionate in rumen of animals received 1000 mg Citrus Limon essential oil, was more than control of treatment, but their concentration of butyrate was low than control treatment (P<0.05). In conclusion, results showed that utilization of 1000 mg per day dose of Citrus Limon essential oil in diet could improve the OM digestibility, rumen fermentation characteristics and blood BHB concentration of male Holstein calves.
