Good livestock practices were evaluated in 25 production systems of small pig farmers in Ibagué (Tolima, Colombia) to measure the conditions of biosafety, facilities, animal health, feeding and administrative management based on the ICA-Colombia resolutions for pig production systems using principal component analysis and clustering. Information was collected on 585 aspects in 52 variables. The results showed that 100% of the producers do not comply with the minimum biosafety standards that a farm must have to be safe, suitable and competitive, which does not allow them to obtain a certification of good livestock practices in pig production. The principal component analysis identified the aspects with the greatest impact that required improvement. The «technical component» was the most relevant, with 58% of the non-conformities, related to sanitary management, biosafety, facilities an...

This review presents the main requirements for measuring multimodal welfare indicators in production animals, from production parameters to physiological parameters, categorized as noninvasive indicators and invasive indicators. It is intended to generate a collection of ideas so that the researcher, in accordance with the limitations, conditions and scope of its resources, evaluate animal welfare for academic purposes, research and optimization of the production and marketing of the final products in a livestock production system.
