Avaliação toxicológica hepática de suínos alimentados com dietas suplementadas com extrato pirolenhoso. 2022. 30f. Trabalho de Conclusão de Curso (Graduação em Zootecnia) - Unidade Acadêmica Especializada em Ciências Agrárias, Universidade Federal do Rio Grande do Norte, Macaíba, 2022.https://repositorio.ufrn.br/handle/123456789/51171Zootechnical food additives, on the order of the best performance, such as antibiotics, are falling into disuse due to the effects that their residues can have on human health through the consumption of products of animal origin, such as meat and milk, for example. It is in this context that the use of additives from plant compounds, such as pyroligneous extract (PE), has been considered. It is the product of the condensation of smoke produced in the carbonization of forest biomass, usually made to obtain charcoal. The benefits of its use in pig production range from good zootechnical indexes, reduction of environmental impacts and reduction of production costs, abdicating the use of some medicines, in addition to its use in the food industry with smoked products. Due to the few studies related to the effects of using this compound in animal feed, it is necessary to deepen it to assess the possible risks for the proper functioning of the animal organism. The objective of this was to evaluate the toxic potential of the pyroligneous extract in the feeding of pigs in the finishing phase, weighing 56.78±8.49kg to 94.41±11.35kg, analyzing the indices of oxaloacetic transaminase (TGO) and pirúvica (TGP) and the liver tissue profile. Twelve pigs, castrated males, were used in the experiment during a period of 40 days and later they were entrusted with humane slaughter. The behavior of the indicators by statistical standard and qualitative evaluation of the images, indicated a reliability in the product, the pyroligneous extract, with low risk, with regard to good liver functioning, profile of its enzymes, aminotransferases, and its tissue configuration.Ácidos orgânicosMorfologia hepáticaToxicologiaOrganic acidsLiver morphologyToxicologybachelorThesisCNPQ::CIENCIAS AGRARIAS::ZOOTECNIA
