This study aimed to investigate the effects of reducing inorganic trace minerals (ITM) by supplementing compound organic (OTM) chelates on growth performance, fecal mineral excretion, intestinal health, and cecal microbiota yellow-feathered broilers. A total 960 one day old male broilers were randomly assigned 6 treatments, among which birds fed with basal diets (negative control, NC), or supplemented 1,000 mg/kg (positive PC), 300, 500 ITM OTM, respectively. Dietary supplementation OTM significantly increased average daily gain (ADG) during 22-53 d 1-53 d, reduced emissions Fe, Cu, Zn, Mn Chinese (P < 0.05). Furthermore, OTM300 group crypt depth in duodenum, ratio villus height (V/C) duodenum jejunum The mRNA expression TGF-β, Bcl-2, CAT, GPX4 as well tight junction proteins (occludin, ZO-1, claudin-1, claudin-5) mucosa when comparing ITM300 Moreover, dietary changed Chao1 index β diversity abundances Firmicutes (phylum), Eubacterium_coprostanoligenes_group (family) Oscillibacter (genus) increased, while Bacteroidetes (phylum) Rikenellaceae RC9 decreased treatment. Spearman correlation analysis showed that occludin jejunal V/C positively correlated abundance but negatively Bacteroidota (phylum). In addition, was TGF-β. PICRUST prediction microbial function revealed treatment enriched pathways related amino acid metabolism DNA replication. conclusion, at lower levels replace could improve performance reduce excretion elements modulation community

Our previous study has shown that replacing 100% inorganic trace minerals with 30% amino acid-chelated ones can enhance antioxidant capacity, improve nutrient digestibility, and reduce fecal excretion in growing-finishing pigs without compromising performance. This aimed to further the content pig diets assess its impact. Seventy-two barrows (Duroc × Landrace Yorkshire), an initial average body weight of 67.04 ± 0.12 kg, were divided into four groups: negative control (NC, no additional minerals), high-dose (HITM, inorganic; 75 mg/kg Fe, 10 Cu, 65 Zn, 25 Mn), two low-dose groups (15 4 12.5 5 Mn) receiving either sulfates (LITM) or acid-chelates (LOTM). The trial concluded when reached ~130 kg. Results showed mineral substitution did not adversely affect growth performance, carcass traits, meat quality, digestibility (p > 0.05). LOTM exhibited significantly higher serum glutathione peroxidase, liver total superoxide dismutase (T-SOD), CuZn-SOD activities, muscle catalase lower malondialdehyde compared LITM < Muscle was than HITM 0.05), but Fe Mn yet level Liver Zn decreased remained unchanged Both reduced emissions greater reductions LOTM. In conclusion, organic negatively growth, pigs, while it effectively heavy metal emissions. Organic more effective enhancing activity deposition.
