Summary: A comparison between supplementing nursery diets with L-glutamine (GLN), antibiotics (AB), or no dietary antibiotics (NA) showed that GLN improved intestinal health markers similarly to AB, while the microbiome composition in GLN pigs was more similar to NA pigs than AB pigs.

Summary: Pork production generates wastewater with high pollutant load and the intensive use of pharmaceuticals leads to effluents rich in these compounds. Traditional biological depuration treatments are effective on organic load removal but are time-consuming and inefficient on abating persistent contaminants like pharmaceutical compounds, necessitating the pursuit of alternative technologies.

Summary: This study investigated the potential of modified bentonite in mitigating the negative effects of combined veterinary antibiotics on anaerobic digestion process treating swine manure. The results showed that the addition of modified bentonite significantly improved the removal of antibiotics and reduced their inhibition on methane production. The cost analysis indicated that the addition of modified bentonite could reduce the cost of antibiotic residue treatment compared to other methods.

Summary: This study systematically investigated the transformation kinetics and pathways of Sulfamonomethoxine (SMM) by UV/H2O2 in swine wastewater. The degradation of SMM in real wastewater was found to be lower than in synthetic wastewater due to the presence of conventional contaminants. Different factors, such as H2O2 dosage, pH conditions, and the presence of carbonate and nitrate, were found to influence the degradation of SMM in the UV/H2O2 system.

Summary: This study investigated the migration of tetracyclines (TCs) during struvite recovery from swine wastewater, revealing that TCs transport is contributed by various processes including the adsorption of pure struvite crystals, struvite adsorbing DOM-TCs complex, and DOM aggregation. Additionally, under alkaline conditions, larger molecular weight DOMs hydrolyze to smaller molecular weight DOMs, promoting the redistribution of TCs among different DOM types.

Summary: African swine fever virus (ASFV) is the causative agent of African swine fever (ASF), which has devastating impacts on animal farming. The interaction of ASFV with the host immune system is complex, hindering vaccine development. Significant advances have been made in vaccine development, but further research is needed for effective ASF vaccines.

Summary: The present study investigated the effects of dietary recombinant human lysozyme (RHL) on the growth, immune response, anti-oxidative activity, intestinal morphology, intestinal microflora, and disease resistance of shrimp Litopenaeus vannamei. The results showed that dietary RHL supplementation significantly improved the growth performance, immune response, intestinal morphology, and disease resistance of shrimp, as well as positively modulated the intestinal microflora.

Summary: In this study, a data-wrangling pipeline was built to integrate diverse and dispersed data streams collected from a swine production company, creating a master table that was used to predict the nursery mortality of groups of pigs. The Support Vector Machine model demonstrated the best overall prediction results, showing high accuracy in forecasting nursery mortality.

Summary: This study investigated the immune potential, growth, and survival of Indian white shrimp post larvae in a biofloc culture system with different salinities. The results showed that shrimp reared in biofloc had higher biomass and survival than those in clear water culture. Among the treatments, shrimp reared in 15 parts per thousand salinity with biofloc showed the best growth and achieved a significantly higher final body weight. The study concludes that lower salinity rearing with biofloc does not significantly affect the growth of Penaeus indicus post larvae.

Summary: This study aimed to investigate the chronic effects and recovery from inhibition in the anaerobic digestion of swine manure containing chlortetracycline. Two reactors were operated for 900 days, with one reactor spiked with CTC. Methane generation and organic removal did not recover within 300 days after CTC exposure was stopped, due to reduced bacterial diversity and shift in microbial species under long-term antibiotic pressure. Continuous exposure to CTC should be avoided for sustainable management of AD plants treating swine manure.

Summary: The aerobic biotreatment process for swine wastewater treatment was optimized using 2-chloro-6-trichloromethylpyridine (TCMP) as a nitrogen fertilizer synergist, to simultaneously achieve antibiotic removal and ammonia retainment. The results showed that a daily dosage of 5-10 mg/L TCMP effectively inhibited nitrification and had varying effects on the removal of COD and tetracycline antibiotics (TCs). The study also found that TCMP had minimal impact on volatilization and hydrolysis, and the overall removal efficiency of TCs was mainly contributed by absorption and biodegradation.

Summary: Antibiotic resistance is a global public health concern, and swine wastewater can be a reservoir for antibiotic resistance genes (ARGs). This study found that the presence of ARGs in swine wastewater during treatment in a three-chamber anaerobic pond (3-CAP) varied across different seasons. Applying swine wastewater in the proper month can help mitigate the spread of ARGs.
