SummaryThe main characteristics of Beldi (meaning “native” in Arabic) poultry raised in rural areas were studied in the Khenifra Region through extensive surveys.Beldi chickens have large phenotypic variability. Black, brown, grey and white colours, pure or mixed, are frequently observed in chickens' featherings while turkeys are predominantly bronze. Plumage types were fairly homogeneous in both species. Single combs and dented combs were respectively predominant in chicken hens and roosters.Sexual maturity was reached at 154 days for roosters, 168 for hens in chicken, around 217 days for toms and 231 for turkey hens. The age at first egg averaged 5.8 months for hens and 8.4 months for turkey hens. The number of eggs laid per hen per year was 78 for chicken and 69 for turkey. Hatchability rate was 78 and 80 percent for chicken and turkeys, respectively. Diseases were the main cause of mortality, which could affect up to 77 percent of chicken flocks.Few preliminary urgent steps for the conservation of Beldi poultry are discussed with other production improvement proposals.

The aim of the paper was to analyse the wind power market in Poland by reviewing the factors that shape and influence its current state and the possible development prospects. The paper was focused on legislative, environmental, manufacturing, sociocultural and economic factors. Barriers to the development of onshore wind power market and the expected development of wind energy in Poland in the years 2017-2020 were identified and measured based on a survey. The review of individual factors and the study performed present that legislative barriers and the introduction of the ‘distance act’ are factors with the biggest influence on the current stagnation of onshore wind energy sector. A review of the recommendations concerning the distance (from protected areas and housing) required to build wind farms set forth in literature shows that Poland is the only country with such harsh restrictions. With its good environmental conditions and technical capacities, Poland can become a European leader in the production of energy from wind. The only barrier is the legislative environment and political instability on the national level. Without improvements in this sector, there is no chance for new wind projects, as these factors are crucial for development of this type of energy.
