Increased dietary zinc oxide changes the bacterial core and enterobacterial composition in the ileum of piglets

Increased dietary ZnO could lead to an increased competition among enterobacteria and, consequently, reduce the occurrence of pathogenic E. coli strains.

Abstract

A high dietary concentration of inulin is necessary to reduce the incidence of swine dysentery

80 g/kg dietary inulin may protect pigs against developing swine disentery by modifying the microbiota in the gastrointestinal tract.

Abstract

Dietary protein/carbohydrate ratio affects on fat deposition and gene expression of finishing pigs

An increase in intramuscular fat in pigs fed low protein diets is related to tissue-specific activation of gene expression.

Abstract

Dietary lysine and energy levels affect on growth performance and apparent total tract digestibility of nutrients in weanling pigs

Increasing dietary lysine and energy levels improves growth performance and apparent total tract digestibility of nutrients.

Abstract

Modeling the fate of dietary phosphorus in the digestive tract of growing pigs

A mathematical model serves as a tool to study phosphorus digestibility for different feedstuffs and feeding strategies.

Abstract

CLA during last week of gestation and lactation alters colostrum and milk fat composition and performance of reproductive sows

CLA administration to sows reduces backfat thickness loss during the lactation period and lets to higher piglet weight at weaning.

Abstract

Glutamine supplementation improves intestinal barrier function in a weaned piglet model of Escherichia coli infection

Glutamine supplementation may be useful in reducing the severity of weaning-related gastrointestinal infections.

Abstract

Folic acid affects performance of suckling piglets and sows during lactation

Supplementation with folic acid in the diets of lactating sows increases milk production, improves milk quality and the performance of piglets.

Abstract

Feed preference in pigs: Effect of selected protein, fat, and fiber sources at different inclusion rates

The preference for the different feed ingredients should be taken into account during diet formulation as well as nutrient composition and ingredients cost.

Abstract

Lysine intake during late gestation on reproductive performance, colostrum composition, blood metabolites and hormones of multiparous sows

Higher lysine levels than those recommended by the NRC improve reproductive performance for multiparous gestating sows.

Abstract

Impact of acetic acid concentration of fermented liquid feed on growth performance of piglets

High levels of acetic acid in fermented liquid feed can impair palatability of piglets.

Abstract

Sow litter size is increased in the subsequent parity when lactating sows are fed diets containing omega 3 fatty acids from fish oil

Feeding omega 3 fatty acids as a way to increase the sows’ litter size.

Abstract

Feed intake restriction and feeding twice or 6 times daily on finishing pigs

Increasing feeding frequency from 2 to 6 times daily increases ADG and feed efficiency of floor-fed, group housed finishing pigs.

Abstract

Easily fermentable carbohydrates reduce skatole formation in the distal intestine of entire male pigs

Chicory inulin and raw potato starch as ingredients to reduce the boar taint of meat from intact male pigs.

Abstract

Dietary lysine levels change processed product characteristics of immunologically castrated male pigs

No differences in further processed product characteristics among physically and immunologically castrated male pigs were found.

Abstract

Metabolic impact of zinc oxide on porcine intestinal cells and enterotoxigenic Escherichia coli K88

The role of zinc oxide in improving piglet health is via a different mechanism to that previously proposed.

Abstract

Dietary crude protein and phytase-xylanase supplementation of wheat grain based diets affect energy metabolism and enteric methane in growing finishing pigs

A combination of dietary crude protein and P reduction with added phytase is the key to optimize pig production efficiency, while minimizing their environmental impacts.

Abstract

Dietary calcium level as calcium carbonate does not affect the apparent total tract digestibility of calcium, but reduces digestibility of phosphorus by growing pigs

The greatest values for apparent total tract digestibility of P are obtained when the dietary Ca to P ratio is around 1.1:1.
