The Effect of Feeding on Environmental Pollutant Emissions in Broiler Production
2020
Özgün Işık | Figen Kırkpınar
Environmental pollution is defined as the disruption of normal ecological balance with emmision of various substances and energy residues as a result of human activities. Animal production is one of the major human activity that enables this emission to increase significantly. Although ruminants play an important role in the effects of animal production on environmental pollutant emissions, the effects of poultry production and broiler production are also worth considering. As in all livestock types, the main factor that has a direct impact on environmental pollutant emissions is feeding for this animal types too. High nutrient needs of broilers and production processes of feed containing these nutrients; greenhouse gas causes increased nitrogen and phosphorus emissions; consequently, they cause air, soil and water pollution to multiply. Changes in protein and amino acid levels or the use of certain feed additives in feeds affect the emission value of broiler production. In addition, the feeding methods also has an effect on these emission values. When these effects are taken into consideration, it is possible to reduce the emission values in broiler production. In this review, environmental effects of broiler nutrition examined in terms of feed production, nutrient emission by manure, presentation of feed and feed form.

2019
Gungor Karakas | Hayriye Sibel Gülse Bal
In recent years, environmental pollution, climate change and excessive use of natural resources have caused problems in the ecosystem. Honey bees are among the most affected by this environmental pollution. Climate change and environmental pollutants cause irregularities in colony development, the formation of weak colonies, the spread of diseases, the inability to return to the hive of field bees, and their mortality and low productivity. Turkey ranks second after China in the production of honey in the world. Honey is a strategic product for Turkey. This study investigated the effect of some environmental pollutants on honey yield in Turkey. This study used the time series analysis covers the years 1990-2017. In the research, honey yield as dependent variable, as independent variables; methane (CH4), carbon dioxide (CO2), diazot oxide (N2O) release, pesticide, insecticide, fungicide, herbicide use and industrial production index were used. After the stationary of the series was tested with ADF Unit Root test, the relationship between the variables was examined by Johansen Co-integration analysis. The effect of environmental pollutants on honey yield was tested by the FMOLS analysis method. According to the FMOLS results, the increase of 1% pesticide use, CH4, CO2, and N2O resulted in a decrease in honey yield of 0.36%, 0.70%, 0.74%, and 0.37% respectively. On the other hand, the increase of 1% insecticide, fungicide, herbicide use and industrial production index caused 0.15%, 0.14%, 0.09% and 0.84% increase in honey yield, respectively.

2015
Muhammed Kamil Öden | Sezen Küçükçongar | Zehra Gök
The purpose of this study is to determine the environmental sensitivity and awareness level of the inhabitants in Konya, Sarayönü districts. In today’s world, the environment is rapidly being polluted and pollution rate is being increased by human beings. In this regards, the viewpoints of Sarayönü people on the environment and environmental elements are revealed. For this purpose, a research include variables such as gender, age, job and education level was carried out by using a questionnaire made up of 16 questions. The questionnaire was applied to 314 males and 286 females, totaling 600 participants. The research serves to raise an awareness of environment and environmental sensitivity. The findings showed that the people in Sarayönü have a high level of environmental sensitivity. Females tended to reflect a higher level of sensivitiy to the environment than males. The participants opted for air pollution as being the most important environmental element among the air, water, soil etc. pollution.
