Dietary fiber plays a crucial role in regulating animal health and production performance. The aim of this study was to investigate the effects of three kinds of corn straw-saccharification fibers (CSSF) such as high-fiber and low-saccharification (HFLS), medium-fiber and medium-saccharification (MFMS), low-fiber and high-saccharification (LFHS) CSSF on the reproductive performance of sows.

One-kilogram CMD consists of 667 g aflatoxin B-degrading enzyme (ADE, 1,467 U/g), 200 g montmorillonite and 133 g compound probiotics (CP). The feeding experiment was divided into 2 stages (1-21 d and 22-42 d).

A total of 350 one-day-old Arbor Acres broilers were randomly divided into 7 groups, 5 replications in each group and 10 broilers in each replication. Group A was the control; group B was supplemented with 75 mg/kg chlortetracycline; groups C, D, and E were supplemented with 0.

The feeding experiment was divided into two stages. In the early feeding stage (1−21 day), a total of 200 one-day-old Ross broilers were randomly divided into four groups; in the later feeding stage (22−42 day), 160 broilers aged at 22 days were assigned to four groups: Group A: basal diet (4.

The results showed that pterostilbene supplementation diminished the oxidation of MP compared to the control, as the carbonyl content was significantly reduced and the loss of sulfhydryl and free amino groups was slowed. Meanwhile, the surface hydrophobicity and insolubility of MP were significantly reduced.

Among the aflatoxins, aflatoxin B1 (AFB1) is a common contaminant of global concern in human and animal food products. Prolonged exposure to AFB1 may provoke hepatocyte pyroptosis and oxidative stress, which leads to liver damage.
View Article and Find Full Text PDFAflatoxin B1 (AFB1) is a mycotoxin widely distributed in animal feed and human food; it represents a serious threat to human and animal health. This study investigates the mechanism by which dietary curcumin protected liver against acute damage caused by AFB1 administration in ducks. One-day-old male ducks ( = 450) were randomly assigned to three groups, the control group, the AFB1 group, and the AFB1 + curcumin group; the first group were fed with basic diet, while the third group was fed basic diet containing 500 mg/kg curcumin.

To investigate these effects, 600 healthy ducks were randomly assigned to four treatment groups with 10 replicates pens, and each pen contained 15 ducks. Ducks were fed a diet containing curcumin at levels of 0, 300, 400, and 500 mg kg in different groups.

A total of 280 one-day-old specific pathogen-free male ducklings () with an average body weight of 35 ± 1 g were randomly divided into two dietary treatment groups with different supplementation levels of resveratrol for growth performance experiments: R and R (0 and, 400 mg kg resveratrol, respectively). At the age of 28 days, 16 ducks were selected from each treatment group and divided into four subgroups for a 2 × 2 factorial pathological experiment: R; R; R + LPS; R + LPS, (0 mg kg resveratrol, 400 mg kg resveratrol, 0 mg kg resveratrol, 400 mg kg resveratrol + 5 mg lipopolysaccharide/kg body weight).

Resveratrol (Res) is a polyphenolic compound with antioxidant, anti-apoptotic and other biological activities; however, it is not clear whether it can improve AFB1 induced hepatotoxicity. Therefore, this study was conducted to investigate the effects of dietary Res on liver injury induced by AFB1 and its mechanisms.

This present study aimed to investigate the effects of dietary curcumin on ileum injury in ducks induced by AFB1 administration and explore its underlying mechanisms. Ducks ( = 450, one-day-old male) with a similar weight were randomly assigned to 3 groups, containing the control group, AFB1 group (60 μg AFB1 kg body weight) and curcumin (500 mg curcumin kg diet) + AFB1 group.

The results showed that dietary resveratrol had no significant effects on the chemical composition. Dietary resveratrol supplementation increased superoxide dismutase, glutathione peroxidase, catalase activity, pH, pH and color, and reduced the malondialdehyde, and carbonyl contents and shear force, thereby improving water mobility and distribution (T, T, T), drip loss, cooking loss and volatile compounds concentration of duck meat.
