Chicks were randomly distributed among the experimental treatments including 0, 0.5, 0.1, and 0.2% levels of whole dill plant powder. In regards to feed intake and weight gain during the entire growing period, the treatments contained 1% and 2% of dill plant powder had the highest and the lowest feed intake, respectively, and treatments containing 0.5% dill powder and control group were in the middle of the first two treatments (P<0.05). In terms of feed conversion ratio, the only significant difference observed between treatments throughout the entire experimental period was a significant increase in the amount of feed conversion ratio in the chicks treated with 2% dill plant powder. Serum alkaline phosphatase concentration showed a significant increase in both assessing periods (21 and 42 days) for the 2% dill plant powder treatment compared to the other experimental treatments (P<0.05). Serum calcium and phosphorus concentrations were not affected by experimental diets. The weight, length, width, and ash percentage of the tibial bone did not show any significant difference between the experimental treatments. The results of this study showed that using 1% of dill plant powder in broiler chicken diets, while improving growth performance, did not have any adverse effect on skeletal growth and development of chickens.

2 - Effect of Pennyroyal (Mentha Pulegium L.) on Performance, Carcass Characteristics and Some of the Blood Parameters in Broilers

Experimental treatments included the levels of zero (control), 0.2%, 0.4%, and 0.6% of pennyroyal powder. The treatment containing 0.6% of pennyroyal powder compared to the control group had higher feed consumption in the starter period (P <0.05). However, there was no significant difference during the growth period and the whole experimental period. In terms of average daily weight gain and feed conversion ratio, there was no significant difference between the experimental treatments during the starter, growth and the whole experimental periods. The carcass percentage decreased significantly at the age of 42 days in treatments containing pennyroyal powder compared to the control group (P <0.05). There was no significant difference between experimental treatments in terms of weight percentage of carcass components including thigh, chest, abdominal fat, heart, liver, and gizzard. The concentration of triglycerides and plasma VLDL decreased significantly in treatments containing pennyroyal powder and decreased linearly compared to the control group (P <0.05). In terms of cholesterol and plasma HDL levels, a significant decrease was observed in treatment containing 0.4 level and treatment containing 0.2 percent of pennyroyal powder compared to the control group (P <0.05) respectively. Plasma LDL levels were not affected by experimental treatments. The results of the present study showed that the use of limited levels of pennyroyal powder up to 0.6% has no significant effect on the performance of broilers. Manuscript profile -

3 - Effects of different levels of Ajowan Trachyspermum ammi as an alternative to antibiotics on growth performance carcass characteristics and some blood parameters of broiler chickens

In this experiment one hundred and sixty one-day-old broiler chicks (Ross 308) were used in a completely randomized design with 4 treatments and 4 replicates (with 10 birds each). The experimental treatments included: 1) control group (without additive2) basal diet + 0.2% Ajowan powder, 3) basal diet + 0.4% Ajowan powder, and 4) basal diet + 0.6% Ajowan powder. Results showed that the levels of 0.2 and 0.4 % had no significant effect on daily weight gain, food intake and feed efficiency. Except for carcass weight, Ajowan had no significant effect on carcass characteristics. For blood parameters, the effects of Ajowan, in most cases, were non-significant. In contrast, plasma LDL and cholesterol concentrations decreased significantly with increasing levels of Ajowan powder. According to the obtained results, based on maintaining the bird's performance at the same levels as the control group and on the other hand improving the pattern of blood lipid metabolites, it can be said that Ajowan can be a good alternative to the growth-promoting antibiotic to improve health and solve the environmental problems in this area.

4 - Investigating the managerial performance of tourism complexes by reviewing socio-cultural components (Case study: Kermanshah Tourism Complex)
Behroz Badko Mohammad Ghasemi Siani Farhad JalalvandiToday, tourism is one of the largest industries in the world and depends on a major part of the global economy; Tourism is economically, socio-culturally and environmentally integrated with the lives of people and governments.

The purpose of this study is to investigate the managerial performance of tourism complexes and present a strategic proposal with emphasis on socio-cultural components in Kermanshah tourism complex. This article examines the managerial performance in four tourism complexes, Rakhsh, Nesar, Nodsheh and Sefid Barg in Kermanshah province. And how can focusing on these components provide successful and appropriate management for the Kermanshah Jihad University tourism complex? This research was conducted using field survey and questionnaire tools presented to 152 people in Kermanshah tourism managers. The results showed that the components of reviving cultural identity and sense of national pride, promoting the culture of tourist reception and retention are ranked first, second and third among all the identified components affecting the managerial performance of tourism complexes, respectively. Accordingly, the emphasis on cultural identity and the necessary training to the managers of the complexes to create a culture of tourist reception has a significant impact on attracting tourists to the tourist complexes of the province.

5 - The Effect of Irrigation Water Salinity and Other Production Factors on Potato Crop yield in Hamadan – Bahar Plain

This has led to a sustained drop in groundwater level in the plain and it has caused it to be among the critical plains of the province. This phenomenon has caused water salinity in addition to damage to groundwater resources. The purpose of this study was to investigate the effect of groundwater salinity on potato yield. In order to investigate the effect of water salinity on potato yield, the yield function of this crop has been estimated. By random sampling method, data used from 119 farms were collected in the 2018-19 crop year and the amount of water salinity has been measured in two steps in the laboratory. Based on the criteria and the test, the production function was selected in the form of a quadratic function for estimating the relationships between variables. The results of this study indicate that with an increase of one unit in the amount of water salinity, the production of this product has decreased by 860 kg. The final productivity of water, seeds and chemical fertilizers are 0.2, 23 and -14, respectively, so, it can be said that potato farmers in Hamedan-Bahar plain use optimum amount of water, seed less than optimum amount and chemical fertilizer more than optimum amount.
