The objective of this work was to review, within the literature, the existing indicators
used to assess the welfare in swine farming, thus substantiating the negative and positive
impacts generated within the system. There has been an immense need for applicability of the
Animal Welfare Science - BEA in swine farming to obtain the expansion of markets (internal
or external), producing quality, ethical products that take maximum care of animal life. Through
research in existing literature, we sought to show the main ways and means of measuring the
quality of life of pigs (in terms of feeding, physiology, health and productivity) in addition to
the conditions provided for in these animals' facilities. Thus, concluding that Brazil's potential
is very large in swine production, but it is noted that it still needs to develop more studies
