In order to investigate the chemical and nutritional characteristics of pea pod silage (PPS) and its effect on the performance of fattening lambs, 24 Zandi male lambs (initial BW, 33.5 ±1.5 kg) were used in a completely randomized design over 75 days. Experimental treatments were: 1) control; (basal diet) 2- pea pod silage (PPS replaced wheat straw and alfalfa in the basal diet). The amount of dry matter (DM), crude protein, ether extract, ash, neutral detergent fiber and acid detergent fiber of PPS were determined 20, 11.8, 1.8, 8, 62 and 20.2 percent, respectively, and pH was 6.02. The rumen degradability potential of DM and in vitro gas production potential of PPS after 96 h of incubation were estimated 83 and 58.6 percent, respectively. The use of PPS in fattening lambs rations improved the final body weight and increased the daily weight gain (P<0.05). The amount of DM digestibility was affected by the treatment (P<0.05), but digestibility of other nutrients was not affected by the experimental treatment. Blood parameters (cholesterol, triglyceride, HDL and LDL) were not affected by the experimental treatments, except for the glucose, which significantly decreased by feeding PPS (P<0.05). The experimental treatments had no significant effect on carcass traits. Based on the results of this study, the use of pea pod silage as a cost-effective alternative forage in replacement with common forages such as wheat straw and alfalfa can improve the performance of fattening lambs.

In order to investigate the effect of feeding milk enriched with garlic powder on performance, digestibility of nutrients, diarrhea status and blood parameters in suckling lambs, twenty-four newborn lambs (birth weight 3.7±0.5) were randomly placed in three treatments and eight replications. The lambs of the control group were fed with milk without garlic powder and the other groups were fed with 1.5 and 3 grams of garlic powder per day, respectively, for 45 days. The results obtained from this research showed that consumption of garlic powder in suckling lambs led to improvement in daily weight gain, final weight and starter feed consumption (P<0.05). Also, treatments caused a significant increase in digestibility of nutrients (P<0.05). The use of garlic powder in experimental lambs improved stool consistency and significantly reduced the number of lambs with diarrhea and the average days of diarrhea (P<0.05). By adding garlic powder, the concentration of glucose and high-density lipoprotein increased (P<0.05). In addition, garlic powder caused a significant decrease in the level of triglyceride, cholesterol and low density lipoprotein in plasma (P<0.05). However, different levels of garlic powder did not make a significant difference on the concentration of urea, albumin, globulin and the ratio of albumin to globulin. According to the present results, it is possible to use garlic powder up to the level of at least 1.5 grams per day as a food additive to improve the performance and health of suckling lambs.

The objective of this study was to evaluate the effect of feeding two oral Ca boluses at calving and 12 h later on feed intake, milk yield, body weight (BW) changes, blood calcium and some reproductive parameters of high producing dairy cows during summer season. Twenty-four Holstein cows with average parity of 2.8 ± 0.8 were selected and randomly assigned to one of two treatments including control or the group receiving slow-release oral Ca bolus at calving and 12 h post-calving. Row milk yield was greater in cows receiving Ca boluses compared to control treatments during 21 days of lactation (P = 0.02). The milk fat (P = 0.01) and solid non-fat percentage (P = 0.05) were greater in cows that received calcium bolus compared to control treatment. In addition, energy-corrected and fat-corrected milk yields increased in cows received Ca bolus (P = 0.03). Plasma glucose and serum calcium concentration as well as BW change were not affected by experimental treatments. The pregnancy per artificial insemination, days to first insemination and open days were not significantly different between the experimental treatments (P >0.05). The results showed that using oral calcium bolus at calving and 12 hours after calving improved milk production and composition, but had no effect on serum Ca, BW change during first 21 days of lactation, and reproduction parameters.

The present experiment was performed to study the effect of slow-release urea on performance traits and some blood parameters of replacement ewe lambs during its replacement with cotton seed meal. The livestock included 16 heads of Afshari replacement ewe lambs. Treatments include: Control containing cottonseed meal, treatment 1 contains 4 grams of slow-release urea in the daily diet (equivalent to 4.45% of dietary crude protein), treatment 2 contains 8 grams of slow-release urea in the daily diet (equal to 8.8% of dietary crude protein), treatment 3 contains 12 grams of slow-release urea in the daily diet (equal to 13.3% of dietary crude protein). The experimental duration included two weeks of acclimatization and forty days of fattening. The studied traits included functional traits and blood parameters. Functional traits included final body weight, feed intake, added daily gain and feed conversion ratio. Blood parameters included total serum protein, glucose, urea, AST, ALT, cholesterol, triglycerides, estrogen, albumin and LDL. The results showed that there was no significant difference between the four treatments in blood parameters. There was no significant difference in final body weight, feed intake, added daily gain and feed conversion ratio between the treatments. Based on the results, it is possible to use up to 12 grams of slow-release urea daily in the diet of ewe lambs without a negative effect on performance.

The aim of the present study was to evaluate the effect of fodder beet on performance, carcass traits and blood parameters of fattening male lambs. 32 fattening male lambs with an initial weight of 28.05 ± 0.25 kg by using a completely randomized block design with four treatments and four blocks for 84 days were fed with experimental diets including control (zero), 10, 20 and 30% fodder beet with the ratio 60% of the concentrate and 40% of the fodder as total mixed ration twice a day. During the experiment period, there was no significant difference in the weight of the lambs among the control group and the groups in which different levels of fodder beet were used in their diets. There was no significant difference in average daily gain among all groups except for the lambs fed with 20% fodder beet diet. In the group that received 30% fodder beet, the feed intake (DM/d) was the lowest compared to other groups (P<0.05). No significant difference in the feed conversion ratio among the experimental groups was observed. There was no difference in slaughter weight, empty-body weight, hot and cold carcass weight, carcass traits and carcass dressing percentage of lambs among different groups (P>0.05). The experimental treatments had no effect on the biochemical characteristics of lambs blood, but fodder beet intake increased blood hemoglobin (P<0.05). Based on the results, fodder beet up to 30% could be used in fattening lamb diets without negative effect on performance, carcass characteristics and blood parameters.

The aim of this study was to investigate the changes in some blood parameters in 15 Lori ewes during pregnancy and compare it with one month before pregnancy and lactation. Blood samples were taken from the jagulur vein before normal mating as a control, at the end of every three months of pregnancy and two weeks after delivery during lactation, and the complete blood cell count of each sample was evaluated by a veterinary cell counter. In extensions, Giemsa staining and differential white blood cell count were performed and total plasma protein values were evaluated by refractometry. The number of red blood cells and the percentage of hematocrits during lactation were significantly reduced compared to pregnancy (P˂0.05). Mean cellular volume was reported in all periods in one spectrum. Decreases in mean hemoglobin levels of red blood cells, mean hemoglobin concentrations in red blood cells and platelet count in pregnancy were observed compared to before mating. The number of leukocytes and neutrophils increased around delivery and decreased after delivery. During pregnancy, the number of eosinophils increased significantly and decreased after delivery (P˂0.05). The number of monocytes and lymphocytes increased in late pregnancy and decreased during lactation (P˂0.05). The amount of total protein in the plasma decreased significantly from 150-100 days of gestation (P˂0.05). Thus, it is concluded that monitoring of changes in blood parameters of Lori ewes, dietary adjustment and preventive measures are necessary to prevent blood disorders such as anemia and thrombocytopenia.

Effect of Basil powder and extract on yield and carcass characteristics, relative expression of heat shock protein gene (HSP70) and some blood parameters of broiler chickens under heat stress using 160 Ross 308 one-day-old broiler chicks in a completely randomized design with 5 treatments and 4 replications (8 chickens per replication), was evaluated for 42 days. Treatments included: 1- Basic diet (control), 2- Basic diet+ Vitamin C (250 mg per kg of grain), 3- Basic diet + 25 mg of Basil powder (per kg of grain), 4- Basic diet +50 mg of Basil powder (per kg of grain), 5- The use of Basil extract (1 ml/liter water). Feed intake, body weight gain, feed conversion ratio, carcass characteristics, blood parameters and relative expression of HSP70 gene in blood were measured. The effects of treatments on blood parameters and carcass characteristics were not significant. Relative expression of the HSP70 gene in the blood was significantly reduced in all treatments compared to the control (P<0.05). Based on the results, basil powder and extract reduce the negative effects of heat stress in broilers, so their use in broiler diets is recommended to prevent heat stress.

In this research the effect of using domestic (Multibehcil) and imported (Bioplus B2) probiotic supplements and Avilamycin antibiotics were investigated on performance, parameters of blood lipid and small intestine morphology by a sample of 360 male Ross-308 broilers aging 11 to 42 days-old in a completely randomized design with 6 treatments, 4 replications and 15 chickens per each replicate. Experimental treatments included 1) without additive (control), 2) diets containing 0.1% of commercial bioplus B2 probiotic, 3) diets containing 0.01% of avilamycin antibiotic and treatments 4) to 6) diets containing 0.05%, 1% and 0.15% of Multibehcil, respectively. The results showed that body weight and feed conversion ratio was improved by using bioplus B2 probiotic and antibiotic (P < 0.05). Body weight and feed conversion ratio in birds receiving 0.1% and 0.15% of Multibehcil were not significantly different from birds receiving bioplus probiotic. Feed intake was not affected by the experimental treatments. Humoral immune response and intestinal morphological parameters in birds receiving 0.15% of Multibehcil was not significantly different from the control group and it was statistically equal to the groups receiving bioplus probiotics and antibiotics. The LDL level of blood showed a significant decrease in Bioplus B2, antibiotic and 0.15% of Multibehcil treatments (P < 0.05). In general, the results indicated that using of Multibehcil at the level of 0.15 percent can be a suitable alternative for both Bioplus B2 and Avilamycin during grower and finisher period in broilers.

The effects of replacement of alfalfa hay and wheat straw with different levels of tarragon plant stalk (TPS) on feed intake, digestibility, microbial protein synthesis, and blood and rumen parameters of sheep were investigated using four Kermani male sheep (BW= 45±2 kg) with approximately three years old in a Latin square design with four 21-day periods. The experimental diets were: 1) control diet (without TPS), 2) diet containing 8% TPS, 3) diet containing 16% TPS and 4) diet containing 24% TPS (DM basis). Dry matter intake, and dietary digestibility of DM, OM and CP were not affected by feeding of TPS in the present research. The amounts of nitrogen intake, nitrogen excreted in the urine and feces, the amount and percentage of retained nitrogen, ruminal pH, ruminal concentrations of NH3-N and volatile fatty acids, and protozoa population were not affected by experimental diets. Feeding different levels of TPS had no effect on, microbial protein synthesis, and concentrations of blood glucose, total protein, urea nitrogen, triglyceride and cholesterol. Results of this study showed that tarragon plant stalk could be replaced with alfalfa hay and wheat straw up to 24% (DM basis) in sheep diet without any effect on ruminal fermentation, blood parameters or feed intake.

The effect of levels of coenzyme Q10 on performance, carcass characteristics, some blood parameters, immune system, organoleptic properties of meat and gastrointestinal tract development of Japanese quails, was conducted using 605 one- day old Japanese quails in a completely randomized design with 11 treatments and 5 replicates from1 to 35 days of age. The experimental treatments included negative control, control, positive control and dietary levels of 15, 30, 45, 60, 75, 90, 105 and 210 mg/kg coenzyme Q10. The feed intake, feed conversion ratio and daily weight gain were measured in whole experimental period. The antibody titers against Newcastle and influenza vaccines and also sheep red blood cells were measured at 30 day of age. The feed conversion ratio was lower in treatment containing 210 mg/kg coenzyme Q10 than negative control treatment (P<0.01). The antibody titers against Newcastle and influenza and also SRBC were significantly increased as dietary level of coenzyme Q10 increased (P<0.01). The blood urea nitrogen concentration decreased by consumption of diets containing coenzyme Q10 than that of negative control treatment (P<0.01). The concentration of red and white blood cells and ileal crypts depth of quails fed diets containing coenzyme Q10 were higher than birds of negative control group (P<0.01). The meat redness and lightness showed improvement in quails fed diet containing 210 mg/kg of coenzyme Q10 in compared with birds of negative control treatment (P<0.01). Based on the results of this study, the addition of coenzyme Q10 up to the level of 210 mg/kg in the diet of Japanese quails improves the performance, blood parameters, immune system, and organoleptic properties of meat.

In order to evaluate the effect of bi-partial toxin binder "Biotox" on health status and productive parameters, sixteen Holstein cows were classified into two groups, biotox (supplemented with Biotox) and control (without Biotox). Feed intake, dry matter intake, body weight, body condition score, rectal temperature, respiratory rate, heartbeat, milk yield and compounds and blood parameters were measured and recorded. In control group feed intake, dry matter intake, body weight and body condition score were significantly decreased from forth to seventh week, while rectal temperature, respiratory rate and heartbeat were increased (P≤0.05) during the entire period. The milk yield increased non significantly during the entire period and significantly (P≤0.05) from fifth to seventh week in biotox group. Content of milk protein (P≤0.05) in biotox group and percent of fat (P≤0.05), percent of lactose (P≤0.05), somatic cell count and concentration of aflatoxin M1 (P≤0.05) in control group were increased. Milk solids content in the biotox group increased non-significantly during the entire period andsignificantly in the fifth to seventh week (P≤0.05). There were no significant difference in concentration of plasma glucose, total protein and creatinine during the entire period, but in control group, creatinine level increased during the late period. Plasma aspartate transaminase (P≤0.05) and alanine aminotransferase (P≤0.05) were higher in the control group. Overall, biotox use improves the health, milk production, and production parameters of lactating cows when the feed is exposed to multiple mycotoxin contamination.

This research was conducted in order to compare the blood parameters and fattening performance of Zel and Dalagh breeds male lambs (three to four months old), and their crossbred with Romanov in different thermal-humidity conditions. Fattening trial was conducted in Gonbad kavous with four treatments and six replicates for 84 days from mid-August to early November. Based on the temperature-humiity index (THI), the lambs were under very severe and severe of heat stress up to 8th weeks of trial, followed by non-stress conditions (THI index of 25.6 and above that, 23.3 up to less than 25.6 and less than 22.2 respectively). In the very severe heat stress condition, the performance of treatments was the same. In the severe heat stress, the performance of Dallagh lambs and their crossbred with Romanov was better than Zel and Zel-Romanov crossbred (P<0.05). In un-stress conditions, performance traits in Zel Romanov crossbred was lower than other treatments (P<0.05). Glucose and cholesterol concentration were lower when the lambs were in heat stress condition than normal time (P<0.05). Unlike, blood urea concentration in heat stress condition was higher than lack of stress time (P<0.05). Concentrations of nonstratified fatty acids (NEFA) in the middle period of experiment, during severe heat stress, were higher than those of very severe and nonstress periods. In whole of fattening trial period, all of the breeds had lower performance than expected, indicating the effects of heat stress on them. Totally, Dalagh breed lams had better fattening performance than Zel and their crossbred with Romanov, especially under very severe heat stress condition.

In order to measure some of the blood serum biochemical parameters in normal rearing conditions and determination of their relationship with body weight and carcass components and also the examination of sex effect on blood biochemical parameters in Isfahan native chicken, an experiment was conducted using 200 one-day-old native chickens. The chicks were reared in completely identical conditions for 12 weeks. At the end of week 12 and after six hours of fasting, the chicks were slaughtered, and their body weight and various carcass components were measured. The cholesterol, triglyceride, total protein, albumin, uric acid, calcium, phosphorus, malondialdehyde, high density lipoprotein and glucose concentrations were measured using commercial kits. The amount of globulin was calculated as the difference of total protein and albumin. The results showed that the highest significant positive correlation (P<0.05) was observed between cholesterol with body weight and thigh weight (0.21) and the highest significant negative correlation was observed between uric acid concentration and liver weight, and between calcium and breast weight (-0.24). The multiple regression analysis showed that cholesterol, globulin and phosphorus parameters could be used to predict body and breast weights, as well as cholesterol and globulin levels for predicting of carcass and thigh weights. In addition, there was no significant difference between two sexes in any of the measured biochemical parameters. According to the results of this experiment, blood parameters could be used to predict some carcass characteristics in Isfahan native chicken.

The purpose of this experiment was to examine the effects of Artemisia Annua L. essential oil (AAEO) and probiotic (lactobacillus acidophilus) as an alternative to antibiotic in feeding laying Japanese quails. A total of 180 46-d-old laying Japanese quails were randomly allocated to 4 dietary treatments in a completely randomized design with 4 replicates of 9 birds, and the experiment lasted up to 109 days of age. The experimental diets were: 1–basal diet as control group (without additive), 2–basal diet plus oxytetracycline (200 ppm), 3–basal diet plus AAEO (250 ppm) and 4– basal diet plus probiotic (4 CFU per kg diet). Results showed that the use of probiotic caused an increase in the egg mass, when compared with control and AAEOtreatments at entire period (P<0.05). The groups fed probiotic and AAEO showed a significant decrease in the serum glucose, cholesterol and LDL levels when compared with those fed antibiotic (P<0.05). Moreover, the group fed AAEO had low lymphocyte and high heterophil counts when compared with those fed diet supplemented with probiotic and antibiotic (P<0.05). In addition, the number of white blood cells and heterophil/lymphocyte ratio in AAEO group were higher than other groups (P<0.05). It can be concluded that lactobacillus acidophilus could be used as a growth promoter in feeding laying Japanese quails.

In this experiment, the effect of oak kernel on digestibility, rumen fermentation and some blood parameters of Arabi sheep and Najdi goat were investigated. In this research, oak kernel (63%) was used for feeding six Arabi sheep and six Najd goats with the mean live weight of 50 ± 3 Kg for 28 days, and digestibility and fermentation, rumination and some blood parameters were measured. Obtained data were analyzed in split plots design. The results showed that dry matter intake and digestibility of dry matter, crude protein and neutral detergent fiber were not affected by treatment and type of livestock. Regardless of the type of livestock, dry matter intake and crude protein digestibility in control treatment was significantly higher and regardless of the type of treatment, the digestibility of dry matter and neutral detergent fibre of goat was higher than sheep (P<0.05). The ammonia nitrogen and pH of rumen between control and oak treatments for goats and sheep was almost the same. Time to eating, rumination and chewing for dry matter, NDF and crude protein between control and oak diets in sheep and goats was not different. Feeding the livestock with oak had no significant effect on the amount of blood glucose, urea nitrogen, cholesterol and triglycerides in sheep and goats. The results of this experiment showed that 63% oak fruit could be used in diet of Najd goat and Arabi sheep.

This study was conducted to evaluate the effects of replacing soybean meal with hempseed meal in diet on performance, egg quality and blood parameters in laying hens. A total of 200 Hy-line 102 wks laying hens were randomly allotted to 25 cages in 5 dietary treatments with 5 replicates (8 birds each replicate). This experiment was conducted in a completely randomized design with 5 treatments involved different ratio of soybean meal to hempseed meal protein source including 1) ratio of 100: 0 protein of soybean meal to hempseed meal (control); 2) ratio of 75: 25 protein of soybean meal to hempseed meal; 3) ratio of 50: 50 protein of soybean meal to hempseed meal; 4) ratio of 25: 75 protein of soybean meal to hempseed meal; and 5) ratio of 0: 100 protein of soybean meal to hempseed meal. Egg production, egg mean weight and feed intake in the birds fed diet contained ratio of 0: 100 protein of soybean meal to hempseed meal were higher than control diet (P<0.05). Albumin height (Haugh unit), yolk color index, yolk weight percentage and shell weight percentage were ameliorated when hens fed diets the highest protein ratio of hempseed meal compared with the control group. Using hempseed meal in diets decreased (P<0.05) the cholesterol, triglycerides and lipoprotein with low density as compared with the control group. It can be concluded that replacing of 75 % and 100% of hempseed meal to soybean meal may improve the performance, egg quality of post molting layer and decrease the serum LDL and cholesterol of laying hens.

An experiment was conducted with 600 one-day-old male broilers (Ross 308) to investigate the effects of Dillaqueous extracts (Anethum graveolens) on blood and growth performance in broiler during a 42-days period. The chickens were divided to four treatments (0, 5, 10 and 20 ml of dill aqueous extracts in drinking water) of five replicates each. Body weight gain, feed intake and feed conversion ratio were measured. At the end of the experiment (day 42), 2 chickens from each replicate were randomly selected and slaughtered. The heart was removed; weights of right and left ventricles were determined separately and ascetic index was calculated. Plasma activity of alanine transaminase (ALT), aspartate transaminase (AST), lactate dehydrogenase (LDH), glutathione peroxidase (GPX), superoxide dismutase (SOD) activity, total antioxidant status (TAS) and Malondialdehyde (MDA) content of plasma were determined. Results showed that 5ml dill aqueous extracts, significantly increased the body weight and reduced the ascetic index, mortality due to ascites and feed conversion ratio (P<0.05). Dill aqueous extracts reduced the plasma glucose level (P<0.05). Dill aqueous extracts at 10 and 20 ml, reduced the plasma triglyceride, lactate dehydrogenase (LDH) activity and increased the plasma HDL (P<0.05). Antioxidant parameters were not significantly affected by treatments. It was concluded that, 5 ml of aqueous extracts of dill could improve the growth performance and reduce the mortality due to ascites in broilers.

In order to investigate the effects of Artichoke leaf powder and vitamin Eon performance, internal organs relative weight and some blood parameters, 240 day-old quails were assigned to four treatments including, basal diet (control), basal diet supplemented with levels of 1.5 and 3 percent of Artichoke leaf powder and basal diet supplemented with 300 mg/Kg diet vitamin E with four replicates and 15 birds in each in a completely randomized design. Birds receiving diet supplemented with vitamin E showed greater body weight gain than other treatments (P<0.05). No significant different was observed in body weight gain between birds receiving diets supplemented with Artichoke leaf powder and those birds received control diet, throughout the experiment. Birds treated with diet containing three percent Artichoke leaf powder had higher feed conversion rate (P<0.05). The concentrations of albumin and HDL were greater in blood serum of birds fed diet containing 1.5 percent Artichoke leaf powder compare to other treatments (P<0.05). According to the results of this study, using Artichoke leaf powder till three percent has no negative effect on feed intake and weight gain throughout the study (1-42 d). Inclusion of 300 mg/kg vitamin E in the diet of Japanese quail improves growth performance during the first three weeks of study.

The effect of honey, royal jelly and bee pollenon performance, immune system and blood factors of Japanese quail, using 160 quail chicks in a completely randomized design by four treatments ]control (without additives), pollen powder 1 g/kg, royal jelly 125 ppm/L, honey 22 g/L) and four replicates of 10 chicks in each replication for 42 days. The experimental groups had no significant effect on feed intake and mortality rate (P>0.05) in whole period. Birds that received honey in drinking water, the best daily body weight gain and feed conversion ratio had compared to other groups. The experimental groups had no significant effect on the antibody production against sheep red blood cells. The highest antibody titers against Newcastle disease and Avian Influenza viruses were related to honey treatment (P<0.05). Addition of pollen to diet, royal jelly and honey in drinking water were significantly affected spleen weight compared to control group (P<0.01). Honey and pollen showed a better response to cell mediated immunity (P<0.01). The use of honey bee products improved blood factors (P<0.01). The results showed that the honey and royal jelly enhanced immunity and performance of the Japanese quails. Furthermore, they were reduced serum glucose and lipids in these birds. Although bee pollenimproved blood factors but it was less effective in improving the immune system and performance.

The effect of feeding silage of leaf and stem of banana tree with waste date palm on feed intake, microbial protein synthesis and blood parameters using four adult rams in a change- over design with four 21-days period were examined. Eighty five kg leaf and stem of banana tree with 15 kg of waste date palm were mixed together and ensiled for 45 days. Chemical composition and sensory evaluation of silage of leaf and stem of banana tree with waste date palm was evaluated and used in experimental diets as zero, seven, 14 and 21 percent of DM. According to sensory evaluations, silage with a score of 20 had a very good rating. Nitrogen retention in sheep fed 21 percent silage was lower than the control group (P<0.05). Dry matter digestibility of experimental diets containing 14 and 21 percent silage was lower than diets containing zero and seven percent silage (P<0.05). The mean excretion of allantoin, uric acid and total purine derivatives in the urine of sheep were increased linearly (P<0.05) with increasing the silage in the experimental diets. Increasing of nitrogen and microbial protein synthesis in sheep fed diet containing 21 percent silage was more than sheep fed diet without silage (P<0.05). Increasing of the silage level in diet, was increased triglyceride concentration by linearly (P<0.05). According to the results, using of 21 percent silage of leaf and stem of banana tree with waste date palm in sheep diet without change in dry matter intake, increase microbial protein synthesis.

To study the effects of various levels of whole cottonseed (WCS) on performance, carcass characteristics and blood parameters, an experiment in completely randomized design (CRD) with four diets containing zero, four, eight and 16 percent WCS on 20 Zandi male lambs with initial average weight 30.4 ± 1.8 kg and 5-6 months old for 90 days was performed. Energy and chemical composition of rations were similar. In comparison of control diet with diets contain WCS in aspect of feed intake, feed conversion ratio, the percent of the carcass and also abdominal fat was significant difference (P< 0.01). The effect of diet on concentration of blood parameters was significant (P< 0.01). Glucose concentration with increasing of WCS in diet was decreasing, whereas concentration of cholesterol and triglyceride in blood increased linearly. This experiment showed that the WCS could be included up to eight percent of the fattening male lamb’s diet.
