The present study examined the effects of fructooligosaccharide (FOS) supplementation in drinking water on the growth performance, carcass characteristics, hematological and biochemical parameters, antioxidant status, and cecal microbiota of New Zealand White (NZW) and APRI rabbits. A total of 180 male NZW and APRI rabbits (aged five weeks; average live body weight 700 ± 39 g) were divided into six groups (30 rabbits/group; 5 replicates/group) in a two × three factorial arrangement. Rabbits of each breed were randomly assigned to one of three treatments of FOS (control; 0.00, FOS-0.5, and FOS-1.0). Results showed that rabbits' final body weight, FBWG, and carcass traits were considerably enhanced compared to those in the control group. The interaction effect of the supplement with the rabbit breed increased the growth, carcass traits, and hematobiochemical and antioxidant parameters with increasing FOS levels. In the cecum of both rabbit breeds, the total bacterial count and population were considerably low, with a substantial increase in the number of supplemented by FOS. In conclusion, FOS supplementation enhanced growth and carcass traits by improving the hematobiochemical parameters and antioxidant status and reducing cecal pathogenic bacteria in both breeds.

Background: This study aimed to evaluate the effects of administering flunixin meglumine (FM) and meloxicam (M) on specific days post-mating on progesterone (P4), total oxidant status (TOS), total antioxidant status (TAS), oxidative stress index (OSI), pregnancy-specific protein B (PSPB), pregnancy-associated glycoprotein (PAG) concentrations and fertility parameters in Awassi sheep.
Methods: Seventy-five Awassi sheep were divided into three groups of 25: control, M and FM. On days 9 and 10 post-mating, the control group received saline, the M group received 0.
Magnolia kobus DC. suppresses neointimal hyperplasia by regulating ferroptosis and VSMC phenotypic switching in a carotid artery ligation mouse model.

Background: Magnolia kobus DC (MO), as a plant medicine, has been reported to have various physiological activities, including neuroprotective, anti-inflammatory, and anti-diabetic effects. However, vascular protective effects of MO remain incompletely understood. In this study, we evaluated the vascular protective effect of MO against ferroptosis in a carotid artery ligation (CAL)-induced neointimal hyperplasia mouse model and in aortic thoracic smooth muscle A7r5 cells.

Dietary Astragalus polysaccharides (APS) get wide application in aquaculture due to their excellent immunoregulatory effects. However, little is known about the effects of dietary APS on vaccine potency in fish. In the present study, large yellow croakers (Larimichthys crocea) were injected with formalin-inactivated Pseudomonas plecoglossicida after APS feeding for 14 d and then challenged by live P.

This study evaluated the effect of wheat germ oil (WGO), Bacillus subtilis, and their combination on growth performance, immune response, nutrient digestibility, intestinal microbial, oxidative status, and gene expression in heat-stressed broilers. Four hundred one-day-old male Ross 308 broilers were distributed into five pens (20 birds/pen) in four experimental groups: a control (CON) without additives, WGO group fed diet with WGO at 200 mg.kg, BS group fed diet with B.
