Phytogenic Compounds Supplemented to Gestating Hyperprolific Sows Affects the Gut Health-Related Gene Expression and Histological Responses in Neonate Piglets.

This research aims to determine whether a specific blend of phytogenic compounds (BPC) supplemented in gestating hyperprolific sow diets can promote prenatal maternal effects in terms of piglet gut function and morphology. Twenty-eight (Landrace × Yorkshire) gilts and sows (parity 0 to 7) were randomly distributed by parity number and body weight into two dietary treatments: unsupplemented Control (CON) ( = 14) or CON diet supplemented with 1 g/kg feed of BPC during gestation ( = 14). The BPC supplementation during gestation of sows downregulated the neonate piglets' jejunal genes involved in oxidation () and nutrient transport (, and ), while and related to immune response and barrier function, respectively, were upregulated ( < 0.

Ginseng Extract Ameliorates the Negative Physiological Effects of Heat Stress by Supporting Heat Shock Response and Improving Intestinal Barrier Integrity: Evidence from Studies with Heat-Stressed Caco-2 Cells, and Growing Broilers.

Climatic changes and heat stress have become a great challenge in the livestock industry, negatively affecting, in particular, poultry feed intake and intestinal barrier malfunction. Recently, phytogenic feed additives were applied to reduce heat stress effects on animal farming. Here, we investigated the effects of ginseng extract using various in vitro and in vivo experiments.

Phytogenic actives supplemented in hyperprolific sows: effects on maternal transfer of phytogenic compounds, colostrum and milk features, performance and antioxidant status of sows and their offspring, and piglet intestinal gene expression.

Phytogenic actives (PA) are plant-derived natural bioactive compounds that may promote livestock health and well-being, as well as improve growth performance and production efficiency. The current study aims to evaluate their effects on sows and their offspring. Eighty-one hyperprolific sows (up to parity 7) were assigned to 3 experimental treatments.

Betaine-rich sugar beet molasses protects from homocysteine-induced reduction of survival in Caenorhabditis elegans.

Purpose: Homocysteine (Hcy) in humans represents a blood-borne biomarker which predicts the risk of age-related diseases and mortality. Using the nematode Caenorhabditis elegans, we tested whether feeding betaine-rich sugar beet molasses affects the survival under heat stress in the presence of Hcy, in spite of a gene loss in betaine-homocysteine methyltransferase.

Methods: Knockdown of the genes relevant for remethylation or transsulfuration of Hcy was achieved by RNA interference (RNAi).

Parameters and techniques to determine intestinal health of poultry as constituted by immunity, integrity, and functionality.

The intestinal microflora lives in intimate contact with its surrounding intestinal wall and the bacteria can exert beneficial or deleterious effects on the host, depending on whether they are classified as probiotics or as pathogens. The interaction is determined on one hand by characteristics of the microorganisms, and on the other hand by characteristics of the intestinal wall. Together they determine the health status of the intestine.
