Economic Effects of Rural Tourism based on (DPSIR) by Using Fuzzy - TOPSIS Method (Case Study: city of Rezvanshahr)

Rural tourism is activities and various types of tourism in different rural areas and around them including the values and different effects for the village environment. Based on this issue, the rural tourism can be known as encompassing various fields of tourism activities such as settlements, events, festivals, sports and recreation that are formed in different rural environment.

This study was applied and its performance method was descriptive and analytical and tried to evaluate the economic impacts of tourism. By using Kuder- Richardson method, reliability of questionnaires was 87% and its validity was achieved 82%. The mixed model was used to identify the priorities based on the measurement of capabilities in the process of spatial development and rural tourism was used on a regional scale and by combining fuzzy model and TOPSIS method was determined in the form of triangular fuzzy ranking index and system parameters tourism and also the selection of criteria were based on DRSIR. Finally, by ranking and prioritization of factors of tourism enthusiastic it was found that this city by having four villages and the natural and cultural attractions, and human as well as four Stock Transportation - Tourism - Services indexes showed intelligence with topics fuzzy algorithm that the services index and tourist attractions are discussed as priorities with higher importance in tourism attraction and allocate higher ratings as indicators that should be considered in order to do his work, respectively. According to investigations, it was found that way- care indicators - catering - cultural attractions, etc. can have an important role in tourism

Effect of a low crude protein diet supplemented with different levels of threonine on growth performance, carcass traits, blood parameters, and immune responses of growing broilers

ABSTRACT A study was conducted to evaluate growth performance, carcass traits, blood serum parameters, and immune responses of Ross 308 male broilers fed diets containing 2 different crude protein (CP) levels (97.5 and 100%) and 4 threonine (Thr) levels (100, 110, 120, and 130% of Ross recommendations for starter and grower periods). A completely randomized block design was adopted and main effects (CP and Thr) were arranged in a 2 × 4 factorial approach. Optimum growth performance was achieved when broiler requirements for CP and Thr were 100% satisfied. The 110% Thr inclusion in 97.5% CP diet increased ADG, ADFI, energy intake, and protein intake (Thr,
