HO-generating casein hydrogels used in food packaging: Rapid photocrosslinking and antimicrobial activity.

Food safety caused by microbial contamination is an important problem that is difficult to solve for the food industry. In this study, a photocurable CFT hydrogel material is prepared by photocrossing casein with the flavin mononucleotide/sodium persulfate system, while flavin mononucleotide and tryptophan are used as photocatalysts to generate hydrogen peroxide (HO) for the inactivation of food pathogenic microorganisms. The CFT hydrogel demonstrated rapid gelation (<3 min), robust mechanical properties (1775 Pa), efficient HO production (75 µM), and favorable biocompatibility.

Effects supplementation of novel multi-enzyme on laying performance, egg quality, and intestinal health and digestive function of laying hens.

This study investigated the effects of multi-enzyme supplementation on various aspects of laying hens, including laying performance, egg quality, intestinal health and digestive function. In total, 384 Jingfen No.6 laying hens at 65-week-age were randomly assigned to four distinct dietary treatments: a basal diet (CON), CON supplemented with 150 g/t multi-enzyme (T1), CON with 300 g/t multi-enzyme (T2), and 600 g/t multi-enzyme (T3).

Effects of dietary multienzymes on the growth performance, digestive enzyme activity, nutrient digestibility, excreta noxious gas emission, and nutrient transporter gene expression in white feather broilers.

Adding multienzymes to poultry feed rations is recognized as a nutritional strategy aimed at improving poultry performance and health status. Nonetheless, some literatures present an ongoing debate about the extent of multienzymes beneficial impact on poultry growth performance. This study aimed to explore the impacts of dietary multienzyme supplementation on broilers, focusing specifically on growth performance, carcass characteristics, apparent nutrient digestibility, excreta noxious gas emission, and intestinal nutrient transporter gene expression.

Effect of a novel alkaline protease from Bacillus licheniformis on growth performance, carcass characteristics, meat quality, antioxidant capacity, and intestinal morphology of white feather broilers.

Background: The present study was conducted to investigate the effects of dietary novel alkaline protease from Bacillus licheniformis on the growth performance, meat quality, antioxidant status and intestinal morphology of broilers. In total, 4000 broilers were randomly assigned into five groups and treated with normal control, normal control + 100 mg kg protease, normal control + 200 mg kg protease, normal control + 300 mg kg protease and normal control + 400 mg kg protease.

Results: Supplementing protease impacted final body weight (linear, P = 0.

Dietary novel alkaline protease from Bacillus licheniformis improves broiler meat nutritional value and modulates intestinal microbiota and metabolites.

Background: Different types of exogenous protease supplements have a positive impact on animal performance, but their effects on the nutritional value of meat and the gut microbial community of broilers have not been extensively studied. The objective of this investigation was to determine the impact of supplementation with a novel alkaline protease derived from Bacillus licheniformis (at doses of 0, 100, 200, 300, and 400 g/t) on the fatty acid and amino acid profiles, inosine monophosphate (IMP) levels, total volatile basic nitrogen (TVB-N) content found within the breast muscle, as well as the impact on the cecal microbiota and metabolites.

Results: Supplementation with 200-400 g/t of the novel protease resulted in a significant elevation in the concentration of essential amino acids (P < 0.

Melatonin supplementation promotes muscle fiber hypertrophy and regulates lipid metabolism of skeletal muscle in weaned piglets.

Melatonin has been reported to play crucial roles in regulating meat quality, improving reproductive properties, and maintaining intestinal health in animal production, but whether it regulates skeletal muscle development in weaned piglet is rarely studied. This study was conducted to investigate the effects of melatonin on growth performance, skeletal muscle development, and lipid metabolism in animals by intragastric administration of melatonin solution. Twelve 28-d-old DLY (Duroc × Landrace × Yorkshire) weaned piglets with similar body weight were randomly divided into two groups: control group and melatonin group.

Lipo-nutritional quality of pork: The lipid composition, regulation, and molecular mechanisms of fatty acid deposition.

Pork is one of the main meats consumed by people, and its nutritional value is closely related to human health. The lipid deposition and composition of pork not only affect the sensory quality but also determine the nutritional quality of pork. The lipids in pork include triglycerides (TAG) and a small amount of cholesterol and phospholipids.

CLA improves the lipo-nutritional quality of pork and regulates the gut microbiota in Heigai pigs.

Conjugated linoleic acid (CLA) is a potential nutritional strategy to regulate meat quality in pigs and produce high-quality pork. However, the effects of CLA on nutritional quality, lipid dynamics, microbiota, and their metabolites in the gut of pigs remain unclear. Our study explored the effects of CLA on lipo-nutritional quality based on a Heigai pig model and investigated the regulatory mechanism using an integrated analysis of multiple omics.

Effects of Dietary Supplementation of Lauric Acid on Lactation Function, Mammary Gland Development, and Serum Lipid Metabolites in Lactating Mice.

Our previous studies demonstrated that lauric acid (LA) stimulated mammary gland development during puberty. However, the roles of LA on lactation in mice remain indeterminate. Thus, the aim of this study was to investigate the effects of dietary LA supplementation on lactation functioning and to study the potential mechanisms during lactation.
