Abstract. The present study aimed at investigating the effects of sumac and dried whey powder on growth performance, carcass traits, intestinal morphology, microbial population, and some biochemical parameters and antibody titer against Newcastle disease of female broiler chicks. A total of 360 1-day-old female broiler chicks with an average weight of 38 ± 0.42 g were randomly divided into three treatments. Each treatment was further divided into six replicates. Three treatments were used: chicks were fed by basal diet as control group, basal diet + 0.02 % sumac powder (S), and basal diet + 0.02 % dried whey powder (DW) for 42 days. Results showed that feed intake of chicks increased significantly in S and DW in comparison with the control group (P < 0.05). Body weight gain was also significantly higher in the treated groups. The serum concentration triglyceride and cholesterol of chicks decreased significantly by S and DW feeding. While low-density lipoprotein (LDL) level decreased significantly, high-density lipoprotein (HDL) levels increased in the S group. Antibody level increased titer against Newcastle disease significantly by feeding treated diet compared to the control group. Data from microbial population investigation showed that E. coli population decreased while Lactobacillus increased in S and DW groups. The data revealed an improvement in the body weight gain, feed conversion ratio because of increased intestinal morphology, antibody level, and some useful microbial population in female broiler chicks receiving the sumac and dried whey powder.

This study investigated the effect of adding Hypericum perforatum to drinkable water in comparison to virginiamycine on performance of broilers and thus on improvement and increase welfare and growth. A total of 400 , one day old broiler chicks with an average weight of 37±50 g were divided into 5 treatment groups and were further subdivided into 4 replicates. The treatments were divided as basal diet with no Hypericum perforatum extract kept as control, and for others 150 mg/l (S1), 200 mg/l (S2) and 250 mg/l (S3) of herbal extract in their Drinking water and virginiamycine (S4) were used respectively. The live body weight gains and feed consumption of birds were measured individually feed conversion efficiency were calculated weekly. At the end of the trial for investigating the effect of using Hypericum perforatum and virginiamycine on performance of broilers, 3 birds form each replicates were slaughtered and some blood samples were taken for determination HDL, LDL, Triglyceride levels and antibody titer against Newcastle vaccine. Data showed that use of S1, S2 and S3 and S4 increased FI significantly (P<0.05) in comparison to control. Also BW and Pre-slaughter weigh at the end of the experiment were also significantly higher (P<0.05) in experimental groups compared to the control. Liver percentage was significantly induced were broilers fed with experimental diets (p<0.05). There were significant differences (p<0.05) for heart percentage between treatments. Using of herbal plant extract could reduce abdominal fat percentage statistically (p<0.05).Percentage of gizzard was higher in the control group and it was at the lowest in virginiamycine group (p<0.05). triglyceride, cholesterol and LDL level decreased significantly in the treated groups while HDL level increased significantly in S1, S2 ,S3and S4. Antibody titers were significantly higher (p<0.05) when broilers were fed by S1, S2, S3and S4. It was determined that herbal and virginiamycine had significant effects on HI test (p<0.05) that compared to control group. Data showed that E. coli population decreased in S1, S2, S3 and S4 while Lactobacillus population increased significantly in S4, S3,S2 and S1 respectively (p<0.05).

This experiment was conducted to evaluate the feeding values of ginger, red and black pepper powder with protexin on performance of Japanese quails. A total 240ten days old male Japanese quails with an average weight of 19 ±5 g were divided into 8 treatments with 3 replicates as randomized factorial design. The quails were fed by basal diet as control diet, 2% ginger, 2%red pepper 2% black pepper powder with or without protexin probiotic respectively. At the end of trial for carcass evaluation 2 birds form each group were slaughtered. Also some parameters such as feed intake (FI), body weight gains (BW), and feed conversion ratio (FCR) were calculated and compared together. Some blood parameters such as cholesterol, triglyceride, high density lipoprotein (HDL), low density lipoprotein (LDL) of quail’s blood were determined. In conclusion it seem that inclusion of ginger, red and black pepper powder in quails diet at level of 2% may be useful and have significantly effects on performance and blood biochemical on Japanese quails

Background & Aim: Dill "Anethum graveolens" is an annual medical plantin the celery family "Apiaceae". It is the sole species of the genus "Anethum".The health advantages of dill seed include its ability to increasedigestive health, as well as providingrelief from insomnia, hiccups, diarrhea, dysentery, menstrual disorders, respiratory disorders, and cancer. This experiment aimed to determine the effects of using different levels of Dill seeds on performance, some blood biochemical parameters and intestinal microbial population in Ross 308 broiler chicks. Experimental: 300 one-day-old male broiler chickswere divided into the four treatments with six replicates and 15 birds each as randomized design. The treatments contained basal diet with no Dill seeds kept as control, and200,400 and 600 gof Dill seedsper each ton of diets respectively. The live bodyweightsgain, feed intake and feed conversion ratio of birdswere calculated weekly. At the end of the experimentfour male birdsform each replicates were slaughtered and dressing percentage were calculated. In addition, some carcass traits and chick's visceral partwere weighed separately as percentage of carcass and some organs weight. Results: Data indicated that using Dill seeds increased feed intake (FI) in treatmentscompared to control.Alsobody weight (BW) (g/d) and Preslaughter weight (g) were higher in groups that werefed by dill seedscompared to the control. Additionally, therewere significant differences (p<0.05) for feed conversation ratio (FCR) among treatments.
