Compostagem de efluente suíno no tratamento de resíduos de fármacos veterinários

Abstract

The increasing need for animal protein has exerted pressures on the current animal production system. One of the alternatives found by producers to improve animal performance has been the use of veterinary drugs, especially antibiotics. However, its indiscriminate use can be a risk to the environmental balance of the producing locations since Brazil has approximately 42 million pigs. With this herd, pig farming represents a great potential for generating environmental impacts. As an alternative use of the large volume of liquid pig manure generated, many producers have been using this slurry in the soil as a bio fertilizer. Residues of veterinary drugs are capable of accumulation with environmental matrices and leach into water resources. In this sense, it is mandatory to dedicate more efforts on the study of techniques and processes for the treatment of organic effluents contaminated by veterinary drugs. Low-cost and environmentally friendly alternative treatment systems are necessary, in order to minimize the entry of these contaminants into the environment. Therefore, the composting process, defined as aerobic microbial decomposition process of organic matter, can be an alternative for treating the effluents contaminated by veterinary drugs. This review to aims to create awareness in the academic community regarding the veterinary drug residues and their contamination potential in different environmental matrices, as well as evaluating the composting process as a technique to minimize the impacts of the swine activity waste on the environment.

Effects of Tetracyclines on Enzymatic Activity and Soil Nutrient Availability

“…Therefore, to evaluate soil fertility, it is important to analyze the enzymes that are part of the biogeochemical cycle of nutrients, including nitrogen, carbon, phosphorus, and sulfur (Lisboa et al 2012). In addition to the implications of nutrient management, large concentrations of antibiotics from livestock production are also found in swine wastewater, suggesting a potential soil impact (Bohrer et al 2019;Casanova et al 2019). In fact, approximately 70% of the antibiotics used in swine production are excreted via animal feces and urine, which contaminate the wastewater (Malintan and Mohd 2006).…”

The Role of Stakeholders’ Understandings in Emerging Antimicrobial Resistance: A One Health Approach

“…Antibiotics have played an essential role in the treatment of numerous infectious diseases, contributing to a significant improvement in the health status of animals as well, and speeding up their growth processes through the control of food-related infections [21][22][23]. This improvement risks being undermined by the increasing spread of pathogens resistant to antibiotics [24][25][26]. The Antimicrobial Resistance Plan 2017-2020 reports that more than 50% of antibiotics used globally are consumed in veterinary medicine [27,28].…”

Rotas de conversão de matéria orgânica em Biodigestores Lagoa Coberta (BLC) no tratamento de águas residuárias de suinocultura

“…Quando controlada, esta resulta na destruição de microrganismos patogênicos devido ao calor produzido durante o processo de degradação (SORATHIYA et al, 2014). A prática é utilizada como forma de degradar os resíduos gerados pelos animais, assim como carcaças de animais mortos, e dependendo de sua qualidade, pode ser aplicada como fertilizante em áreas de pastagem (BOHRER et al, 2019).…”
