Present study was designed to investigate the effect of Artichoke (Cynara Scolymus) extract on performance and some blood and anti-oxidantparameters of Sanjabi lambs. Eighteen Sanjabi lambs were randomly allocated to three experimental treatments with six replicates in each individualcage for 75 days. The experimental treatments were: 1) control group including basal diet without Artichoke extract, 2) basal diet plus 5 ml ofartichoke extract, and 3) basal diet plus 10 ml of artichoke extract per kilogram dry matter. The blood samples were collected from jugular vein oflambs before feeding at morning monthly. The concentration of glucose, cholesterol, total protein, urea, albumin, and the activity of glutathioneperoxidase, superoxide dismutase, alkaline phosphatase, alanine aminotransferase enzymes and malondialdehyde were measured. The results of thisexperiment showed that artichoke extract had no significant effect on lambs' performance and growth parameters, but significantly decreased bloodconcentration of cholesterol, triglyceride and malondialdehyde index at the level of 10 ml extract per Kg/DM of diet. The urea and cholesterolconcentrations affected by time and at days 40 of experiment, the amount of this parameters was lower than other times. In general, it can beconcluded that artichoke extract at the level of 10 ml extract had no significant effect on average daily gain and growth performance of lambs butimproved some blood parameters.

A total of 24 male and female Sanjabi suckling lambs with an average weight of 4.2 kg at birth day were used in a 90-day trial period using randomized complete block design for evaluation of two dietary antioxidants. The lambs were received forage and concentrate from the second week of birth in addition to maternal milk. The experimental diets included control (milk and starter), control + 10% lemon balm (Melissa officinalis) and control + one tablet CoQ10 (30 mg). Every 30 day of experiment blood samples were drawn from jugular vein to measure some hematological and enzymatic parameters. No significant difference was observed among treatments for daily milk, dry matter intake and performance of lambs. Hematocrit was not affected due to lemon balm but it was increased (P<0.05) by CoQ10. Diets containing antioxidants increased the total white blood cells compared to control (P<0.05); but monocytes and basophils did not alter these parameters. Lemon balm reduced the lymphocytes and increased neutrophils while CoQ10 did not influence these two parameters. Eosinophil in blood samples of lambs received Lemon balm or CoQ10 were more than that of control (P<0.05). The concentrations of glutathione peroxidase, immunoglobulin-G and total antioxidant capacity were not affected by treatments, but lemon balm supplementation decreased (P<0.05) malondialdehyde index. The results of this experiment showed, the use of lemon balm in 10% of diet as well as 30 mg/day of coQ10 in suckling lambs’ diet improved immune system, however no significant changes observed in the performance of the lambs.

Forty multiparous Holstein cows were used to investigate the effect of supplementary rumen protected Conjugated linoleic Acid (CLA) with injectable Se and vitamin E (E-Se) supplement on immune system in Holstein cows and their calve in a commercial dairy farm at Ghazvin province. The animals were divided in four experimental groups in a complete randomize design based on factorial. The experimental groups were: basal diet (Control), basal diet plus injectable E-Se Supplement, basal diet plus CLA 100 g/day per each cow) and basal diet plus CLA 100 g/day per each cow and Injectable E-Se Supplement. The dose of injectable E-Se supplement was 40 ml/cow. The injection has done muscularly in each cow in days, -21, 1, 14, 28 and 42 after calving. Blood Samples of cows collected at days of injection. Blood samples of calves collected at birthday pre feeding colostrum and 7 days after birth. The result showed CLA supplement had no significantly effect on mean concentration of Immunoglobulin G (IgG), Total antioxidant status (TAS) and Malondialdehyde (MDA) in calves on days 1 and 7 (P>0.05). Effect of injectable E-Se Supplement on TAS concentration of Calve's Plasma had was significant (P>.05). CLA and injectable E-Se Supplements had no significant effect on mean concentration of IgG, TAS and MDA of cow`s colostrum (P>0.05). The CLA and E-Se supplements had no significant effect on TAS concentration and hematology Parameters of dairy cow (P>0.05). Based on acquried result use of CLA supplement in transition period had no effect on immune system of cows and their calves. Supplementary injection of E-Se significantly improved total antioxidant status of newborn calves.

The possibility of manufacturing and effects of a slow release non-protein nitrogen product on ruminant nutrition were evaluated in two separate experiments. In first experiment, making of slow release component was followed by connecting branched carbon chain to the molecule of urea to reduce the degree of solubility. Then, the sample product was analyzed to assess its chemical structure, and also physical and chemical properties. In second experiment, in an in-vivo study, rumen fermentation characteristics, digestibility of feed, microbial protein production and nitrogen balance of produced compound were evaluated and compared with conventional use of urea and also a diet without non-protein nitrogen source. For this, four rumen fistulated adult sheep were used in change over Latin square experimental design. Infrared and proton magnetic resonance spectroscopy and physical and chemical properties were considered as indicators of the formation of the desired compound. Our data showed that using the slow release product in the diet reduced the nitrogen concentration and altered the amount and ratio of volatile fatty acids as well as pH values in the rumen. Feed intake and digestibility of dry matter, organic matter, NDF and ADF as well as microbial protein production were not affected by the use of slow released product but there were significant differences between diets in relation to the nitrogen digestibility and nitrogen balance (P<0.01). It could be concluded that the slow release product of non-protein nitrogen has the potential to provide urea efficiently and its use in ruminant diets provides safer conditions as compared to the traditional use of urea nitrogen.

20 one-month-old Sanjabi suckling lambs (ten males and ten females with initial liveweight of 13.4 ± 1.3 and 11.6 ± 0.9, respectively) were used to assess the effect of ad libitum creep mixture on dry mater intake, live weight gain and carcass characteristics. The lambs were blocked within sex according to their live weight and randomly allocated to one of two treatments, control (free suckling and free choice of alfalfa) or supplementary (ad libitum creep mixtures with free suckling and free choice of alfalfa) in a 2 × 2 factorial arrangement. The study was continued for 100 days and at the end of the experimental period, all lambs were slaughtered to assess carcass characteristics. Average daily milk intake of males was higher than females (P< 0.01). Daily live weight gain (g/d) was significantly (P< 0.01) higher in males than females (240 vs. 163 g/d) and in the supplementary group than the control (259 vs. 145 g/d). Fat tissue in both male and female lambs in supplementary group was significantly (P< 0.01) more than that in the control. It could be concluded that the creep mixture diet improved growth rate and carcass characteristics and the fat content of the lambs.

A total of 16 suckling Merghoz kids, comprising eight male and eight female with birth liveweights of 2.7 ± 0.11 and 2.3 ± 0.16 kg, respectively were used in a 2 × 2 factorial arrangement. The kids were blocked within sex according to their liveweight and randomly allocated to one of two treatments: ad libitum good quality alfalfa hay in addition to free suckling (control) or ad libitum creep mixture in addition to free suckling and free choice good quality alfalfa hay (creep mixture). Daily feed intake and liveweight changes of all kids were recorded during the study. Skin biopsies and fibre samples were taken every 15 and 28 days, respectively. Average daily dry matter and milk intake by the kids were similar in the four groups. Kids in creep mixture diet showed higher value of average daily gain (P< 0.05). Sex and dietary treatment had no significant effects on secondary follicle density and the S/P ratio in the skin. In contrast, the mean values of both primary and secondary follicular index were significantly different under the influence of sex and dietary treatment (P< 0.05 and P< 0.01). It is concluded that follicular index and growth rate in suckling Merghoz kids were increased due to using creep mixture diet.
