&NA; The effects of supplemental dietary threonine (Thr) on laying performance, expression of intestinal mucin 2 (MUC2) and secretory IgA (sIgA), and intestinal microbiota of laying hens fed a low CP diet were investigated. A total of 240 Lohmann Brown laying hens, 28 wk of age, was allocated to 3 dietary treatments, each of which included 5 replicates of 16 hens. Hens were fed a control diet (16% CP), a low CP diet (14% CP), or a low CP diet supplemented with 0.3% L‐Thr for 12 weeks. Chemical…

Alterations and Correlations of the Gut Microbiome, Performance, Egg Quality, and Serum Biochemical Indexes in Laying Hens with Low-Protein Amino Acid-Deficient Diets

The correlation analysis showed that amino acid deficiency-induced gut microbiota alteration is closely associated with the change in key parameters: FER, UA, AFY, EW, EM, TG, FBW, EP, and ADFI, which highlight the role of adequate amino acid ratio supplementation in the low-crude-protein diet structure for laying hens.

Dietary supplementation with fermented plant product modulates production performance, egg quality, intestinal mucosal barrier, and cecal microbiota in laying hens

Fermented plant product (FPP) is a kind of functional complex containing probiotics and a variety of bioactive substances, which has multiple physiological functions. However, there is no systematic

Diet complexity and L-threonine supplementation: effects on growth performance, immune response, intestinal barrier function, and microbial metabolites in nursery pigs.

Feeding a simple diet to nursery pigs resulted in systemic and intestinal inflammation and the SUP Thr diet did not normalize the simple diet-induced inflammation but improved gut integrity, and SUP Thr seems to have greater benefits with asimple diet than with a complex diet.

A Comparison of Production Performance, Egg Quality, and Cecal Microbiota in Laying Hens Receiving Graded Levels of Vitamin B12

Overall, dietary supplementation of 100 or 400 μg/kg of vitamin B12 had equivalent effects and caused the significant change in composition and metabolic functions of cecal microorganisms, which could positively impact eggshell quality, metabolism, and gut health of laying hens.

A deficient or an excess of dietary threonine level affects intestinal mucosal integrity and barrier function in broiler chickens.

Findings suggested that Thr might be a nutrient immunomodulator that affects intestinal barrier function, moreover, 125% of the NRC (1994) recommendations Thr level was optimum.

Dietary High Sodium Fluoride Impairs Digestion and Absorption Ability, Mucosal Immunity, and Alters Cecum Microbial Community of Laying Hens

Dietary high F intake increased the F residuals in duodenum, and reduced the digestion and absorption of nutrients and immunity via decreasing the activities of digestive enzymes, impairing intestine mucosal immunity, and disturbing the cecum microbial homeostasis of laying hens.

Effects of dietary threonine supplementation on productivity and expression of genes related to protein deposition and amino acid transportation in breeder hens of yellow-feathered chicken and their offspring

Dietary supplementation with Thr had positive effects on the laying production by breeder hens and offspring performance, and it also regulated the expression levels of genes related to amino acid transportation and protein deposition.

Maternal dietary linoleic acid altered intestinal barrier function in domestic pigeons (Columba livia)

Maternal dietary LA might alter intestinal barrier function in pigeon squabs in a dose-dependent manner and improve intestinal morphology, gene expression of tight junction proteins, immune cytokines, and microbial flora in squabs.



Effect of excess dietary threonine on laying performance, egg quality, serum free amino acids, and digestive enzymes activities of laying hens during the postpeak period

It is shown that feeding laying hens from 56 to 64 wk of age l -Thr up to 2.0 g/kg can improve laying performance and Haugh units and Supplementing the diet with l-Thr did not affect egg weight or feed intake, but egg mass increased significantly.

Intestinal mucin dynamics: response of broiler chicks and White Pekin ducklings to dietary threonine.

A link between dietary Thr and intestinal crude mucin dynamics in chicks for experiment 1 and ducklings for both experiments is established, and there was no effect of Thr on intestinal goblet cell density or MUC2 mRNA abundance for broilers.

Effect of supplemental L-threonine on mucin 2 gene expression and intestine mucosal immune and digestive enzymes activities of laying hens in environments with high temperature and humidity.

It was concluded that dietary threonine requirements as reported in current NRC recommendations are insufficient for modern commercial laying hens raised in summer climates, and it was suggested that l-threonine might function as a nutrient immunomodulator in maintaining intestinal barrier function.

Effects of dietary fiber and reduced crude protein on ammonia emission from laying-hen manure.

Results of this study showed that dietary inclusion of 10.0% corn DDGS, 7.3% WM, or 4.8% SH lowered NH(3) emission from laying-hen manure; however, reducing the CP content by 1 percentage unit had no measurable effect on NH( 3) emission.

The effect of dietary protein level and total sulfur amino acid:lysine ratio on egg production parameters and egg yield in Hy-Line W-98 hens.

A 3 x 3 treatment arrangement varying in dietary protein and TSAA:Lys was used to evaluate the effect of low-protein diets fed to Hy-Line W-98 laying hens, producing eggs with improved shell quality as compared with other ratios during P1 and P2, respectively.

Threonine needs of broiler chickens with different growth rates.

The Thr needs in 3 commercial broiler strains known to differ in terms of feed intake, growth rate, and breast yield were evaluated and the plasma Thr sigmoid response verified the former estimates.

Dietary threonine restriction specifically reduces intestinal mucin synthesis in rats.

Results clearly indicate that restriction of dietary threonine significantly and specifically impairs intestinal mucin synthesis and consequently reduce gut barrier function.

Effect of Low Protein Diets with Amino Acid Supplementation on Broiler Growth

Abstract Reduction of litter N and ammonia production can be accomplished by decreasing dietary CP to levels below the requirements listed by the National Research Council. However, amino acids must

Effect of dietary protein content on ileal amino acid digestibility, growth performance, and formation of microbial metabolites in ileal and cecal digesta of early-weaned pigs.

Lowering the dietary CP content combined with supplementation of AA markedly reduced the production of potentially harmful microbial metabolites in cecal digesta of early-weaned pigs without affecting growth performance and fecal consistency scores.

Impact of dietary protein on microbiota composition and activity in the gastrointestinal tract of piglets in relation to gut health: a review.

It seems to be a promising approach to support growth and metabolic activity of the beneficial microbiota by developing suitable feeding strategies, and a reduction of dietary CP content and dietary supplementation with fermentable carbohydrates have proven to successfully suppress protein fermentation.
