“…, 2001). Further compounding the problem is that most CAFOs administer antibiotics to the livestock for prophylactic and therapeutic purposes (Aaarestrup and Jenser, 2007). Although the occurrence frequency remains unknown, prolonged usage of antibiotics can result in acquisition of antibiotic resistance genes (ARG) in a certain portion of the commensal microbiota (Blake et al.…”

“…Besides the presence of noxious gases, faecal microbiota were also found to aerosolize to a mean airborne concentration of around 10 5 cfu m -3 within the animal confinement buildings (Chang et al, 2001). Further compounding the problem is that most CAFOs administer antibiotics to the livestock for prophylactic and therapeutic purposes (Aaarestrup and Jenser, 2007). Although the occurrence frequency remains unknown, prolonged usage of antibiotics can result in acquisition of antibiotic resistance genes (ARG) in a certain portion of the commensal microbiota (Blake et al, 2003;Nandi et al, 2004;Cocchi et al, 2007), which can become aerosolized within the animal confinement buildings.…”

Summary Given the growing concerns over human and animal health issues related to confined animal feeding operations, an in‐depth examination is required to monitor for airborne bacteria and associated antibiotic resistance genes. Our 16S rRNA‐based pyrosequencing revealed that the airborne microbial community skewed towards a higher abundance of Firmicutes (> 59.2%) and Bacteroidetes (4.2–31.4%) within the confinement buildings, while the office environment was predominated by Proteobacteria (55.2%). Furthermore, bioaerosols in the confinement buildings were sporadically associated with genera of potential pathogens, and these genera were more frequently observed in the bioaerosols of pig and layer hen confinement than the turkey confinement buildings and office environment. High abundances of tetracycline resistance genes (9.55 × 102 to 1.69 × 106 copies ng−1 DNA) were also detected in the bioaerosols sampled from confinement buildings. Bacterial lineages present in the poultry bioaerosols clustered apart from those present in the pig bioaerosols and among the different phases of pig production, suggesting that different livestock as well as production phase were associated with a distinct airborne microbial community. By understanding the diversity of biotic contaminants associated with the different confinement buildings, this study facilitates the implementation of better management strategies to minimize potential health impacts on both livestock and humans working in this environment.

“…Strategies, for example the use of enzymes, organic acids, antibiotics, probiotics, prebiotics, and active phytochemicals for controlling enteric infection, improving animal immunity, and ameliorating intestinal function (including modulation of intestinal microbiota) are common approaches to combat stress and to maximize animal production. In the past several decades, antibiotics have been used extensively in the commercial production of food-producing animals to prevent enteric infection and to promote animal growth (Shuford and Patel 2005;Aarestrup and Jenser 2007), which has contributed significantly to agricultural economy and food supply security worldwide. However, this practice has been under close scrutiny because it threatens public health due to antibiotic residues in food animal products (Mortier et al 2005;Kozˇa´rova´et al 2011) and the spread of antibiotic resistance in zoonotic bacterial pathogens (Williams Smith 1970;Hayes et al 2004).…”

Review: Chinese herbs as alternatives to antibiotics in feed for swine and poultry production: Potential and challenges in application

2014. Chinese herbs as alternatives to antibiotics in feed for swine and poultry production: Potential and challenges in application. Can. J. Anim. Sci. 94: 223Á241. Traditional Chinese medicine (TCM) has a long history of clinical practice, and its own theoretical framework focused on functions at the whole-body level. However, due to cultural differences, TCM has not been fully recognized in Western countries. With the recent development of the theory of whole-body systems biology and ''-omics'', there is a new opportunity to study TCM and to close the gap between TCM and Western medicine, because of the similarity in the theoretical foundations between TCM and whole-body systems biology. The uniqueness of TCM theory and practice is the approach to maintain and restore the body balance as a whole with no or little unfavourable side effects. Recent studies have also shown that Chinese herbs used as feed additives can modulate nutritional metabolism, immune responses, and intestinal health of food-producing animals, demonstrating good potential as substitutes for dietary antibiotics. Nonetheless, some issues need to be addressed before Chinese herbs can reach their full application. This article has critically reviewed recent progresses in scientific research of Chinese herbs as feed additives and their potential to replace dietary antibiotics. Possible challenges in future application for swine and poultry production are also discussed.

“…Los supuestos de cómo pueden actuar los AH al suplementarse como aditivos son diversos, ya sea como antibiótico, ionóforo, antioxidante, antiinflamatorio, anabólico o mejorador de la palatabilidad, y en la mayoría de los casos sin comprometer la salud y calidad de la carne (34,35) (Figura 1). En contraste con algunas sustancias sintéticas que se usan por tiempo limitado y en ciertas etapas del crecimiento animal, al menos los AH u otros compuestos fitoquímicos no se han encontrado limitantes en una fase de crecimiento específica en el animal o posible daño por efectos residuales de estos compuestos (36,37,38) .…”

El uso de aditivos de origen natural en producción animal ha tomado gran importancia en el sector pecuario, debido a su potencial de promover el crecimiento de una forma similar a los compuestos sintéticos como hormonas y antibióticos, pero sin causar posibles daños a la salud del animal, del consumidor o detrimento en la calidad de la carne. En los aditivos de origen natural existe una amplia variedad de compuestos, que son extraídos de distintas partes de las plantas, donde se toman ciertos aceites esenciales, mezclas de compuestos o compuestos aislados para utilizarse como remedios medicinales o suplementos alimenticios. Dentro de estos extractos, se encuentran los ácidos hidroxicinámicos, presentes en una gran variedad de vegetales, frutas y granos; los cuales presentan interesantes propiedades bioactivas como son, antioxidantes, antimicrobianos, preventivos de enfermedades cardiovasculares e inmunomoduladores. El uso de este tipo de aditivos en producción animal aún es limitado, pero se sugiere que su inclusión puede ser favorable como una estrategia para promover el crecimiento; sin embargo, dos aspectos importantes a estudiarse en los ácidos hidroxicinámicos es su farmacocinética y farmacodinamia, y a partir de allí establecer las condiciones de dosis, períodos de uso y efectos, además las posibles rutas y biotransformaciones que pueden ocurrir en el organismo animal. Esta revisión discute sobre la inclusión de ácidos hidroxicinámicos en dietas de animales de engorda, propiedades farmacocinéticas y farmacodinamias, y los hallazgos como promotores de crecimiento y sus efectos en la calidad de la carne.
