Given the increasing share of striking the livestock sector in the national economy is of great interest to know which are emissions generated by this and their influences on environmental  factors. This paper aims to examine correlations that exists between emissions in atmosphere by notching animal farms and meteorological factors. To realize this work I make some measurements at various livestock farms. Noted that all the farms are located in different zone of  the Bihor county, where the weather conditions and topography are different. I note that measurements were made with a sampler for particulate matter and with a digital gas analyzer type Oldham MX21.I also has been used mathematical simulation of dispersion of pollutants generated by equations of mathematical physics. n the equations, leading to simulate pollutant dispersion is found meteorological factors such as wind speed, temperature, upward movement of air masses, humidity, etc. Initially it presents briefly, to highlight the technological process emissions at every stage of the technological process and also in order to extract their properties. Theme paper is not addressed in the first, but certainly is a topical issue through themes. Theme is studied by the scientific community of all countries with focus on environmental protection and the development of society in correlation with the principles of sustainable development. In this connection European scientific communities are remarkable efforts that try to achieve standards that must be respected in the breeding activities. Practical implications of research, importance of work: This paper proves its usefulness especially for guiding entrepreneurs in choosing the best locations for future Agrozootechnical firm and providing information indicative of policy makers in the field of environmental protection in such an objective economic analysis.The importance of the work result by highlighting how emissions from the activity of pigs in a growth industry affects livestock farming communities.
