A novel mycotoxin-degrading enzyme complex can biodegrade AFB, DON, and ZEN co-contamination in both in vitro and in vivo experiments.

A novel mycotoxin-degrading enzyme complex (MDE), developed via a microcapsule coating process and containing three degrading enzymes, exhibits the ability to biodegrade aflatoxin B (AFB), deoxynivalenol (DON) and zearalenone (ZEN). This study aims to evaluate the efficacy of MDE against AFB, DON, and ZEN through in vitro and in vivo experiments. In vitro simulated digestion experiments revealed that the MDE degraded the concentrations of AFB, DON, and ZEN by 76.

Validation with the Dynamic Prediction Model of Protein and Amino Acid Requirements for Growth Performance and Health in Layer Chicks.

This study evaluated an established dynamic prediction model for protein and amino acid nutritional requirements on growth performance and health in layer chicks. A total of 288 one-day-old healthy Jing Tint 6 chicks were randomly divided into four treatment groups with 6 replicates of 12 chicks each. The chicks in the four groups were fed a basal diet (BD) according to the feeding standards and a model diet (MD) based on the dynamic prediction model for protein and amino acid values at 90%, 100%, or 110% for 6 weeks.

Dietary Supplementation of Zinc Oxide Quantum Dots Protective Against Induced Negative Effects in Broilers.

is a major cause of necrotizing enteritis in chickens. This study aimed to investigate the effects of zinc oxide quantum dots (ZnO-QDs) on growth performance, redox status, and gut microbiota in broilers challenged with . A total of 320 1-day-old chicks were divided into five groups: negative control (NC) without treatment; positive control (PC) infected with ; and the other three groups (40, 80, and 120 Zn) were given ZnO-QDs at doses of 40, 80, and 120 mg/kg, respectively, under infection, respectively.

AMPK-mediated energy metabolism disorders are associated with impaired type IIB muscle fiber regeneration in broiler chickens with wooden breast myopathy.

Wooden breast (WB) myopathy is a myodegenerative muscle disease, in which muscle regeneration is also commonly observed, and has been increasingly reported in fast-growing broilers in recent years. This study aims to investigate the underlying mechanism of energy metabolism abnormalities on muscle regeneration in WB. A total of 300 male Ross 308 broilers were evaluated at 42 days of age based on physical and biochemical examinations to classify the severity of WB.

Hepatoprotective effects of dandelion against AFB-induced liver injury are associated with activation of bile acid-FXR signaling in chicks.

This study aimed to investigate the protective effects of dandelion against AFB-induced hepatotoxicity through the regulation of the FXR signaling pathway in chicks. A total of 144 one-day-old male broilers were randomly assigned to three groups and received a basal diet (BD), and BD supplemented with 0.5 mg/kg of AFB or 0.

T-2 toxin-induced splenic injury by disrupting the gut microbiota-spleen axis via promoting IL-6/JAK/STAT1 signaling-mediated inflammation and apoptosis and its mitigation by elemental nano-selenium.

T-2 toxin is one of the most toxic A trichothecene mycotoxins prevalent in the environment and food chain, which brings severe health hazards to both animals and humans and it can significantly damage immune function. In this study, we comprehensively explained the impact of T-2 toxin on the spleen through gut microbiota-spleen axis by integrating the transcriptome and microbiome. Our results revealed that dietary T-2 toxin ≥ 1.

A novel zearalenone lactonase can effectively mitigate zearalenone-induced reproductive toxicity in gilts.

Zymdetox Z-2000 is a novel zearalenone (ZEN) lactonase produced by Bacillus subtilis that can biodegrade ZEN to hydrolyzed ZEN and decarboxylated hydrolyzed ZEN with much lower estrogenic activity. This study aims to evaluate the efficacy of Zymdetox Z-2000 in mitigating the adverse effects of ZEN on the growth performance and reproductive health of gilts. A total of 80 crossbred Landrace × Yorkshire gilts (9.

Effects of Dietary Supplementation of Zinc Oxide Quantum Dots on Growth Performance and Gut Health in Broilers.

This study aims to investigate the effect of different levels of zinc oxide quantum dots (ZnO-QDs) on the growth performance and gut health in broilers. A total of 1125 1-day-old Ross 308 broilers were randomly divided into five groups with 15 replicates of 15 chicks each. The broilers were fed basal diets supplemented with 0, 40, 80, 120, or 160 mg Zn/kg as ZnO-QDs for 6 weeks.

Estimation of Protein and Amino Acid Requirements in Layer Chicks Depending on Dynamic Model.

Four trials were conducted to establish a protein and amino acid requirement model for layer chicks over 0-6 weeks by using the analytical factorization method. In trial 1, a total of 90 one-day-old Jing Tint 6 chicks with similar body weight were selected to determine the growth curve, carcass and feather protein deposition, and amino acid patterns of carcass and feather proteins. In trials 2 and 3, 24 seven-day-old and 24 thirty-five-day-old Jing Tint 6 chicks were selected to determine the protein maintenance requirements, amino acid pattern, and net protein utilization rate.
