Background: Deoxynivalenol (DON) is a widespread issue for feed and food safety, leading to animal and human health risks. The objective of this study was to determine whether ferroptosis is involved in DON-induced intestinal injury in piglets. Three groups of 21-day-old male weanling piglets (n = 7/group) were fed a control diet, or diet adding 1.

The full-length cDNA encoding the 10 GST isozymes (GST, GST3, GSTM3, MGST1, MGST2, MGST3, GSTK1, GSTT1, GSTO1 and GSTZ1) were isolated/synthesized from ducks' liver and cloned into the pcDNA3.1(+) vector.

A total of 3,507 feed samples, including 2,090 feed ingredients and 1,417 complete feed samples, were collected from different areas of China for mycotoxins analysis.
Results: The individual contamination of AFB, DON and ZEN were present in more than 81.
The objective of this study was to explore the mechanism of (HD) in mediating the detoxification of aflatoxin B (AFB)-induced hepatic injury in chicks. A total of 144 one-day-old male broilers (Cobb 500) were randomly assigned to four treatment groups ( = 6 cages/diet, 6 chicks/cage). After three days of acclimation, the broilers were fed either a control diet (Control), Control plus 0.

Three hundred and sixty 26-week-old Roman laying hens were randomly allocated into four experimental groups with 10 replicates of nine birds each. The four groups received either a basal diet (BD; Control), a BD supplemented with 0.

Four groups of day-old broilers were allocated into a 2 × 2 factorial design trial that fed a Se-deficient based diet (BD) or the BD + 1.0 mg AFB/kg, 0.

Four groups of 21-day-old male piglets (n = 7/group) were fed either a control diet, or diet containing 1.0 or 3.

Four groups of 21-day-old male piglets (n = 7/group) were fed a control diet or diet containing 1.0 or 3.
View Article and Find Full Text PDFAflatoxin B (AFB) widely contaminates staple food and feed crops and is well-known as the most potent natural hepatocarcinogen in humans and domesticated animals. This review highlights significant advances in our understanding of the pivotal role of phase I and II metabolizing enzymes in the bioactivation and detoxification of AFB and its metabolites across species. In humans, cytochrome P450 (CYP) 1A2, CYP3A4, CYP3A5, and CYP3A7 in liver and CYP2A13 in lung are essential for the bioactivation of AFB to the extremely toxic exo-AFB-8,9-epoxide (AFBO), whereas CYP1A1, CYP1A2, CYP2A6, and CYP3A4 are important in the turkey and duck, CYP1A1 and CYP2A6 are important in the chicken and quail, CYP3A11 and CYP3A13 are important in mice, and CYP2A5 are important in the hamster.

A total of 1569 samples, including 742 feed ingredients and 827 complete pig feed samples, were collected from various regions of China for mycotoxins analysis. The results showed that individual occurrence rates of AFB₁, ZEN, and DON were more than 83.
