“…Since the first use of antibiotics for poultry in 1940’s [ 1 – 3 ] and for swine in 1950’s [ 4 – 6 ], they have been widely used for prophylaxis to handle issues with diseases as well as for growth promoting as antimicrobial growth promoters (AGP) in animal production [ 7 – 9 ]. However, due to emerging concerns over resistance to antibiotics for human, the use of AGP in animal feeds has been restricted or banned in several countries including Sweden (1986), Denmark (1995), EU (2006), Korea (2011), USA (2017), China (2020), and Vietnam (2020) [ 10 – 12 ].…”

In the modern pig production, pigs are weaned at early age with immature intestine. Dietary and environmental factors challenge the intestine, specifically the jejunum, causing inflammation and oxidative stress followed by destruction of epithelial barrier and villus structures in the jejunum. Crypt cell proliferation increases to repair damages in the jejunum. Challenges to maintain the intestinal health have been shown to be related to changes in the profile of mucosa-associated microbiota in the jejunum of nursery pigs. All these processes can be quantified as biomarkers to determine status of intestinal health related to growth potential of nursery pigs. Nursery pigs with impaired intestinal health show reduced ability of nutrient digestion and thus reduced growth. A tremendous amount of research effort has been made to determine nutritional strategies to maintain or improve intestinal health and microbiota in nursery pigs. A large number of feed additives have been evaluated for their effectiveness on improving intestinal health and balancing intestinal microbiota in nursery pigs. Selected prebiotics, probiotics, postbiotics, and other bioactive compounds can be used in feeds to handle issues with intestinal health. Selection of these feed additives should aim modulating biomarkers indicating intestinal health. This review aims to define intestinal health and introduce examples of nutritional approaches to handle intestinal health in nursery pigs.

“…Como fue señalado, esos peligros se incrementan por las falencias en el manejo de los residuos de la actividad, como lo ejemplifican los 16 000 cerdos muertos a causa de una epidemia en 2013, que fueron arrojados al río Huangpu, que abastece de agua a Shanghái (Lü, 2013;Trápaga Delfin, 2017). La salud humana puede verse comprometida asimismo por el ingreso de los residuos de antibióticos o microorganismos que generaron resistencias a la cadena alimentaria (Schoenmakers, 2020;Zhang et al, 2021).…”

El severo impacto ambiental de los actuales patrones de producción y consumo de alimentos y la pandemia de covid-19 otorgaron una inusitada relevancia a la transformación del sistema agroalimentario a nivel local y global. Este trabajo explora las implicancias de las acciones de China para la protección de su industria porcina tras la epidemia de peste porcina africana, en la trayectoria del sistema agroalimentario global. Para ello se estudió el proyecto de instalación de granjas porcinas en Argentina negociado en 2020. Mediante un diálogo del enfoque neogramsciano de la economía política internacional con los estudios agrarios críticos, se argumenta que esa iniciativa demuestra que, pese a los efectos ambientales y sanitarios, el interés de China no es transformar su modelo de producción porcina, sino trasladarlo hacia nuevos territorios. De ese modo, China reconstruye su liderazgo porcino y afirma su poder dentro del modelo agroalimentario hegemónico.

“…In 2013, more than half of the antibiotics produced in China were used for animals [40]. Although animal antibiotics consumption has decreased rapidly since 2014, the total antibiotic use in animals is still high [41]. The antibiotics have the potential to be taken up by dropwort planted on LW.…”

The rapid growth of the livestock and poultry industries has resulted in the production of a large amount of wastewater, and the treatment of this wastewater requires sustainable and environmentally friendly approaches such as phytoremediation. A substrate-free floating wetland planted with water dropwort (Oenanthe javanica), a common vegetable in Southeast China, was constructed to purify a lagoon with anaerobically and aerobically treated swine wastewater in Suqian, China. The average removal rates of total nitrogen, ammonium nitrogen, nitrite nitrogen, and chemical oxygen demand were 79.96%, 95.04%, 86.14%, and 59.91%, respectively, after 40 days of treatment. A total of 98.18 g∙m−2 nitrogen and 19.84 g∙m−2 phosphorus were absorbed into plants per harvest through the rapid growth of water dropwort biomass, and the nitrogen accumulation ability was similar to that observed of other plants, such as water hyacinth. In addition, the edible part of water dropwort was shown to comply with the Chinese National Food Sanitation Standards and be safe for human consumption. Its low soluble sugar content also makes it a suitable addition to the daily diet. Overall, substrate-free floating constructed wetlands planted with water dropwort could be more widely used for livestock wastewater purification and could be integrated with plant–livestock production in China because of its high removal efficiency and recycling utilization of water dropwort biomass.

How China is getting its farmers to kick their antibiotics habit

Abstract: Worries about antimicrobial resistance and disease outbreaks have pushed farms to decrease drug use and improve hygiene. By Kevin Schoenmakers Pigs at some farms in China are monitored using surveillance cameras to help keep them healthy.
