Global Perspectives of Intensive Animal Farming and Its Applications

Agricultural farming outputs are dependent upon the production type because different farming systems create different products. Intensive animal farming is widely used for the production of products that have societal importance, including meat, milk, wool, leather, fur, eggs, and honey. To ensure their timely production with limited cost, advanced technological processes, and chemicals (pesticides, herbicides, and fertilizers in large amount) are carried out in this intensive factory farming. Amongst animal farming, the livestock sector is the fastest-growing agricultural sector. The global shift toward intensive animal farming for high productivity yield has rendered a negative impact on the environment and biodiversity and is now an alarming sign for global warming. It has also resulted in soil, water, and air pollution due to the emission of greenhouse gases from the waste generated by these animals. Rapid use of antimicrobials in these farming systems has led to the emergence of drug-resistant pathogens. Therefore, an integrated and comprehensive approach covering the nonmarket outputs of the farming system is required for monitoring these global trends.
