Nguyen University of Supervisors Agriculture and Forestry, Vietnam Abstract: Each year livestock industry emits about 75-85 million tons of waste has an impact on the environment and human health in many ways such as causing pollution of surface water, groundwater, atmosphere, environmental soil and agricultural products Environment polluted by the decay of organic matter in pig manure and wastewater After the waste discharged, If we don’t give the right treatment I will bring plenty of consequences By this research You could have the overall looking to the real environmental situation of pig farm now a day in USA The environmental policy laws of water quality, air quality, soil quality etc Beside, I’m Lu an going to describe deeply of automatic technology in the modern farm Then analyze va the benefits and disadvantages of those things At the end, I wrote the results of n measurement of Air sample, water sample, and soil sample By this way to th ac understanding more clearly

pork products worldwide has resulted in the construction of Concentrated Animal Feeding Operations and waste lagoons as means of industrializing production A closer look at hog production of this kind in eastern North Dakota, USA, reveals that while profits are spiraling upward, the burdens of extreme environmental damage and health hazards are shouldered disproportionately by minority communities and the rural poor Leaders of the Environmental Justice movement struggle to defend their communities and capture the attention of the general public People love pigs, and pigs create waste An increase in global demand for pork products has driven a trend of concentration and industrialization in hog production worldwide, creating pockets of densely packed pig farms Meanwhile, one hog can produce as much as four to eight times the feces as a human being The combination of Lu these factors leads to an environmental and human health crisis that now plagues many an n va rural communities ac th This is the story of the eastern coastal plain region of the state of North Dakota si in the USA, which has become a hog-production haven At 9-10 million strong, the w population of the pig herd here outnumbers residents; the flat, sandy landscape is o nl ad speckled with ‘lagoons’, which are literally pools of hog waste the size of football va an lu fields These lagoons have become emblems of the painful decades-long fight for local residents, primarily African Americans and rural poor, to defend their communities l ul nf from crippling air and water pollution t n oi m Page z z These all above reasons tell us why pig industrial is very important now a day They develop very fast and heavy effect to environment too The question here is how to good combine between environment and benefit It is not different things, it barely two side of one problem To get higher economy benefit, the farm not only should care about the diet, reproduction or health management but also should care about environment In opposite way, if good environment will ensure for Sustainable Development in long term, prevent the diseases, get high quality of pork To find out the relationship between environment and pig growth I conducted research projects:“Assessment of how environmental factor can effect to the pig growth in Nelson county pigs cooperative, Lakota, North Dakota, United State” 1.2 Objectives of the study - Surveying the status of waste in pig farming is applied at the ranches - Assess the level of pollution by livestock activities at the camp through environmental indicators - Dedicate the diseases of the sows, piglets Then find out the relationships with around environment Lu an 1.3 The significance of the thesis va n Meaning science th ac • The research results contribute the new perspectives on the importance of the si environment in livestock w • The theme is a reference material for learning and scientific research in the future ad o nl Practical significance • The findings of the research will provide the basis for the relationship between l ul nf va an lu benefits and environmental protection t n oi m Page z z Positive effect on the environment of biogas as stated above is undeniable However, the biogas system is not the final treatment system to ensure eligibility safe discharge into the environment So that is the reason they empty the tank every months and bring out the waste to functional waste treatment place 4.3 Assessment of environmental quality in Nelson County Pigs Cooperative 4.3.1 Calculate the total of waste mass in farm Figure 5:

volume of the tank M3 V=15*Q So, the capacity of the waste water storage tank is: Lu an V waste water = 15*(1.528 N1 + 0.778 N2) = 22.92 N1 + 11.67 N2 (m3) va Where: N1: number of sows- 2500 be
