  Effects of various levels of energy and L-carnitine on meat quality and serum lipids of Japanese quail were examined. This experiment was carried out using 480 quails in a completely randomized design with two levels of energy (2900 and 3100 kcal kg-1) and three levels of L-carnitine (0, 250 and 500 mg kg-1) by factorial arrangement. Four replicates with 20 quails were allocated to each experimental treatment and birds were reared for 42 days. At the end of the experiment, two birds from each experimental unit were selected and after slaughter and separation of carcasses, thigh and breast samples were transferred to the freezer to asses meat quality parameters. The results showed that using of higher levels of energy increased the amount of blood cholesterol and triglyceride (p<0.05). The quails were fed with ration containing L-carnitine supplementation, had lower triglyceride in comparison with control group (p<0.05). Higher levels of energy increased the amount of crude fat and malonaldehyde in breast samples. The amount of malonaldehyde in breast samples after storage for 90 days and amount of crude fat and malonaldehyde in thigh samples after storage for 30 and 90 days were affected by different levels of L-carnitine, so that using of 250 mg kg-1 L-carnitine significantly reduced the amount of malonaldehyde in breast samples and crude fat and malonaldehyde in thigh samples (p<0.05). Therefore, it can be concluded that the supplementation of diet with L-carnitine has positive effects on blood triglyceride and meat quality in Japanese quail.

  The objective of present study was to investigate the effects of various levels of L-carnitine on performance, egg quality and blood parameters of laying Japanese quail. This experiment was carried out using 128 quail in a completely randomized design with four levels of L-carnitine (0, 125, 250 and 500 mg/kg). Four replicates with 8 quails were allocated to each experimental treatment and birds were reared from 35-70 days. The results showed that there were no significant differences in feed intake and egg production among experimental treatments (p>0.05). The effect of L-carnitine on feed conversion ratio was significant (p<0.05). The quails were fed with rations containing L-carnitine had lower feed conversion ratio (p<0.05). Adding of L-carnitine supplementation (125 and 250 mg/kg) significantly reduced egg yolk cholesterol and triglyceride (p<0.05). Dietary L-carnitine supplementation had no significant effect on other egg quality parameters (p>0.05). The quails were fed with ration containing L-carnitine supplementation (125 mg/kg) had lower blood triglyceride (p<0.05). Furthermore, L-carnitine at levels of 125 and 500 mg/kg significantly reduced blood cholesterol in comparison with control group (p<0.05). Based on current results, it can be concluded that supplementing diet with L-carnitine will reduce blood triglyceride, cholesterol and improve egg quality in laying Japanese quail.

  This experiment was conducted for investigation, the influence of prebiotic, garlic powder and turmeric powder on interior organs and hematological indices of broilers. Based a randomized completely design, 240 days old Ross 308 broilers were distributed into 16 floor pens and reared for 42 days. A basal diet was formulated according to NRC recommendations for starter (0-21 days) and grower (22-42 days) periods. The basal diet was also supplemented with prebiotic Biolex-MB, garlic powder and turmeric powder, resulting 4 dietary treatments were prepared including control group. Each dietary treatment was fed ad-libitum to 4 replicates group of 15 birds at the bigining of rearing period. The lowest (p<0.05) abdominal fat percent and serum cholesterol and triglycerides levels were recorded for broilers fed the diet supplemented with Biolex-MB and garlic powder, While, the highest High Density Lipoprotein (HDL) was recorded for birds fed diet supplemented with garlic powder. Inclusion of Biolex-MB and garlic powder into the diets significantly decreased concentration of Low Density Lipoprotein (LDL) and Very Low Density Lipoprotein (VLDL) in serum (p<0.05).

  This experiment was conducted for comparison, the effect of garlic powder, black cumin seeds powder and wild mint powder on performance and carcass characteristics of broiler chickens. Based a randomized completely design, 320 days old Ross 308 broilers were distributed into 16 floor pens and reared for 42 days. A basal diet was formulated according to NRC recommendations for starter (0-21 days) and grower (22-42 days) periods. The basal diet was also supplemented with garlic powder, black cumin seeds powder and wild mint powder, resulting 4 dietary treatments were prepared including control group. Each dietary treatment was fed ad-libitum to 4 replicates group of 20 birds at the bigining of rearing period. There were no significant differences in feed consumption at all of treatments in rearing period (p>0.05). The birds fed the diet containing black cumin seeds powder had the highest body weight gain as compared with other treatments (p<0.05). The best Feed Conversion Ratios (FCR) was recorded with birds fed diets contained black cumin seeds powder compared with control and other groups through all growing periods (p>0.05). The lowest (p<0.05) abdominal fat percent were recorded for broilers fed the diets supplemented with garlic powder and black cumin seeds powder (p<0.05). Also, the highest carcass percent were recorded for birds fed diets supplemented with black cumin seeds powder and garlic powder (p<0.05). The percent of breast in birds received black cumin seeds powder significantly was higher than wild mint and control groups (p<0.05). The percent of thigh was not affected with feed treatments (p>0.05).

  This experiment was conducted for comparison the effect of some feed growth promoter additives on carcass characteristics, internal organ weights and hematological indices of 21 days old broiler chickens. Based a randomized completely design, 300 days old Ross 308 broilers were distributed into 30 floor pens and reared for 21 days. A basal diet was formulated according to NRC recommendations for starter (0-21 days) period. The basal diet was also supplemented with antibiotic (Flavomycin), probiotic (Primalac), prebiotic (Biolex-MB) and mixture of primalac plus Biolex-MB (as synbiotic), resulting 5 dietary treatments were prepared including control group. Each dietary treatment was fed ad libitum to six replicates group of 10 birds at the bigining of rearing period. The highest (p<0.05) thigh percent was recorded for broilers fed the diet supplemented with Flavomycin, meanwhile the lower values were shown for birds fed diet supplemented with primalac. The percent of abdominal fat followed the same trend. Compared with control birds group, all other treatment groups fed growth promoter diets improved the percent of heart, but these differences were significant (p<0.05) only for biolex-MB and mixture of primalac plus biolex-MB group treatments. The percent of bursa of fabricius in primalac and mixture of primalac plus biolex-MB supplemented groups were significantly (p<0.05) higher than those in control group. The highest cholesterol concentrations were recorded for birds fed both control and diet supplemented with flavomycin groups while least concentration was found for birds fed diet supplemented with primalac.

  Effects of a probiotic (PRIMALAC) and a prebiotic (FERMACTO) on performance, ileum and crop microbial flora and carcass characteristics have been examined on 480 1 day old Ross 308 broiler chicks. The experiment carried out in a factorial design including three levels of FERMACTO (0, 1 and 2 g ton-1) and two level of Perimalac (0 and 900 g ton-1). Each of treatment was allocated to 5 replicates of 16 male broilers and reared for 42 days. The microflora population in crop and ileum parts was measured on appropriate bacteriological media. Results of experiment indicated that application of primalc (900 g ton-1) significantly improved body weight gain and feed conversion ratio (p<0.01). Feed consumption and feed conversation ratio were not affected with supplementation of different levels of FERMACTO. The percent of carcass, thigh, breast and abdominal fat were not affected by treatments. Coliform counts in the ileum of birds receiving PRIMALAC (900 g ton-1) and FERMACTO (2000 g ton-1) were significantly lower than those of the control birds (p<0.05). Different levels of PRIMALAC or FERMACTO had no effect on total bacteria counts in the ileum and crop parts. In 3rd week of rearing periods, the highest significant (p>0.05) value of lactobacilli population was recorded for broilers fed diet supplemented with PRIMALAC (900 g ton-1) but different levels of FERMACTO relatively increased lactic acid bacteria population in crop. The results of present study revealed that these feed additive by acting on microbial population of digestive system significantly (p<0.05) affects broiler performance.

  An experiment was conducted to evaluate the effects of different levels of probiotic and prebiotic on growth performance and carcass characteristics of broiler chickens. About 480 sexed male Ross 308 hybrid chickens were used. The birds were assigned six treatment groups in a randomized complete block design. Each treatment allocated to 5 replicates of 16 male broilers and reared for 42 days. The broiler chickens were grown on starter (0-21 days) and grower (22-42 days) diets calculated to meet NRC recommendations and supplemented with different levels of probiotic PRIMALAC (0, 900 g ton-1) and prebiotic FERMACTO (0, 1000 and 2000 g ton-1). Body weight and feed consumption were determined weekly during the study. Each dietary was fed ad libitum in the whole of experiment. The result of present study showed that the interaction effect between different levels of PRIMALAC and FERMACTO was significant. The highest value of body weight gain was recorded for broilers fed the diet supplemented with mixed of PRIMALAC (900 g ton-1) and FERMACTO (2000 g ton-1) (p<0.05). Lowest feed conversion ratio was belonging to prebiotic (2000 g ton-1) group and caused more efficient feed intake. The highest significant (p<0.05) value of carcass and breast were recorded for broilers fed diet supplemented with mixing PRIMALAC and FERMACTO. The percent of carcass, thigh and abdominal fat were not affected by treatments. The results of present study revealed that supplemented diets with mixed of PRIMALAC and FERMACTO (symbiotic) as growth promoters appeared to be superior compare to use alone and improve broiler chickens growth indices.

  This experiment was conducted to evaluate the effects of different levels of Hatchery Wastes (HW) on performance, tibia ash, blood calcium and phosphorus concentrations in broiler chickens. Birds were fed a corn-soybean meal diet for 7 days. The experimental treatments included a corn soybean meal diet and 3 other treatments containing 1.5, 3.0 and 4.5% HW. five replicate groups of 15 Ross 308 broiler chicks were allocated to each dietary treatment. Data were analyzed in a completely randomized design. Results indicated that there were no significant differences in weight gains among different dietary treatments. Feed intake in the 4.5% treatment was significantly higher (p<0.05) and 3% treatment had lower feed intake than the other treatments. The results indicated that feed conversion in the 3% HW treatment was lower in most of the period (p>0.05). Results of carcass analysis showed no significant differences between treatments. Also, there were no significant differences between blood calcium and phosphorous among treatments. The 4.5 and 3.0% hatchery wastes treatments had the highest tibia ash (p<0.05). Based on the result of this experiment, the utilization of hatchery wastes as much as 3% can increase tibia strength without having adverse effect on broilers performance.
