Summary: This study evaluated the impact of either removing antimicrobials from pig diets or substituting them with feed additives during the nursery and growing/finishing stages. The results showed that replacing antimicrobials with additives did not affect pig performance, but the cost of antimicrobials or additives per kg of feed produced did impact the cost per kg of pig produced.

Summary: The combination of autochthonous Bacillus spp. (probiotics) and fructooligosaccharide (FOS, prebiotic) significantly improved growth, feed utilization, and protease activity in Indian major carp fingerlings. Supplementation of probiotics and synbiotics enhanced haematology, serum biochemistry, and immune parameters in fish. After experimental exposure to a pathogenic bacterium, synbiotics application boosted immunity and relieved physiological stress, resulting in higher survival rates. The use of synbiotics containing autochthonous bacilli and FOS is recommended to improve growth, immunity, and pathogen resistance in fish.

Summary: Adding EM to the feed of tilapia can significantly promote fish growth, but the improvement in immunity is not significant. Some gene expression in the brain and hepatopancreas is significantly affected by EM feed.

Summary: The excessive and indiscriminate use of antibiotics in the poultry industry has led to serious consequences, including threats to human and animal health and the accumulation of residues in the environment. Therefore, finding alternatives for safe meat and eggs production has become of paramount importance, leading to the increased use of biological products in poultry production.

Summary: This study applied mixed probiotics to the three-stage fermentation of functional feed and investigated the optimum ratio of inoculation, optimal time of inoculation, combination of substrates, and nutritional value of the fermented feed. The results showed that the fermented feed significantly improved protein content, reduced pH, and decreased the levels of antinutritional factors. Animal trials confirmed the growth-promoting effects and improved immune properties, relative abundance of fecal microflora, especially lactobacillus.

Summary: This study demonstrated the feasibility of using dewatered swine manure-derived biochar (DSMB) as an additive to enhance anaerobic digestion of swine wastewater for energy recovery and antibiotic resistance gene degradation. DSMB was found to accelerate methane production, reduce antibiotic resistance genes, and mitigate the risk of horizontal gene transfer, presenting a win-win solution for bio-waste management in swine farms.

Summary: The present study aimed to characterize the in vitro properties of Ligilactobacillus salivarius strain PS21603 and evaluate its tolerance in piglets as a feed additive. The study found that L. salivarius PS21603 had a high antimicrobial activity, was tolerant to low pH and bile, and showed resistance to osmotic changes. Whole genome sequencing confirmed the absence of antibiotic resistance genes. In an in vivo 28-day study, L. salivarius PS21603 was found to be safe and well tolerated by piglets, with no differences in performance or cytokine profiles. The results suggest that L. salivarius PS21603 is a potential candidate for preventing piglet diarrhea using probiotics.

Summary: Antibiotic usage in swine husbandry contributes to the emergence and dissemination of antibiotic-resistant bacteria, posing a serious threat to public health. In this study, the substitution of metaphylactic antimicrobials with the administration of the probiotic strain Ligilactobacillus salivarius MP100 showed beneficial productivity and quality outcomes. The probiotic intake did not negatively affect the meat composition and was associated with an increase in inosine concentration and a slight tendency for increasing the intramuscular fat content, which are considered as biomarkers of meat quality.

Summary: The study demonstrated that nucleotide supplementation had a similar effect to antibiotics on piglet performance and was superior in enhancing intestinal health. Nucleotides improved gut health by modulating local immune response and intestinal mucosa development, suggesting they may be an alternative to antibiotics as growth promoters.

Summary: The study investigated the use of probiotics in promoting embryonic and pullet growth in laying hens. The application of in ovo probiotics significantly improved embryo weight, length, hatchability, and hatchling weight. Additionally, sustained probiotic supplementation was found to be the most effective in promoting growth.

Summary: The co-composting of solid and liquid manure presents a potential game changer strategy for direct recycling of livestock wastes and reducing environmental contamination. By systematically investigating promoting factors and nutrient enrichment models, this technique can elongate thermophilic duration, enhance organic matter degradation, and enrich nutrient concentrations in the final compost, offering an environmentally friendly and unique advantage for simultaneous management and recycling of livestock wastes.

Summary: The use of in-feed probiotics in different growth stages has positive effects on growth performance, hematological parameters, gut microbial content, and morphological structures of pangasius fish, as well as increasing fry survival rate. The treated groups showed significantly higher growth performances, survival rates, and levels of specific hematological parameters compared to the control group, indicating the potential benefits of using probiotics in nurseries for pangasius.
