Caroline González-Vega (Cargill)    This study was conducted to investigate the effects of medium-chain fatty acid blend (MCFA) and a phytogenic feed additive (Fresta® Protect, Delacon, Austria) on growth performance and gut health of Escherichia coli (ETEC)-challenged pigs. A total of 200 weaned pigs with initial body weight of 5.52 ± 0.17 kg were allotted to 40 p ...

The objective of this experiment was to determine the effects of dietary crude protein (CP) content and crystalline amino acids (CAA) supplementation patterns on the growth performance of weaned pigs under clean (CSC) or unclean sanitary conditions (USC). One hundred forty-four piglets (6.35 ± 0.63 kg BW) were housed under CSC or USC for 3 wk and assigned to 1 of 3 diets: a high CP (HCP; 21 ...

A study was conducted to evaluate the effects of replacing corn by full-fat rice bran (FFRB) on performance and meat quality characteristics of growing-finishing pigs. A total of 728 pigs [Duroc x (Yorkshire x Landrace); initial body weight (BW) = 24.1 ± 0.11 kg] were randomly distributed to 4 dietary treatments with 7 replicate pens (26 pigs/pen) per treatment. Diets 1, 2, 3 and 4 were for ...

Functional amino acid supplementation during disease challenge enhances growth performance and immune status. The present study investigated the effect of duration of adaptation period to a functional amino acid (FAA)-supplemented diet on growth performance and immune status during a subsequent Salmonella challenge in pigs. Thirty-two mixed-sex weanling pigs (8 pigs/treatment; 11.6 ± 0.34 k ...

Distillers dried grains with solubles (DDGS) has a high concentration of Leu, and the Trp requirement for growing pigs may be increased if diets contain excess Leu. Therefore, the objective of this experiment was to determine the optimum standardized ileal digestible (SID) Trp:Lys ratio in growing pigs fed diets with excess Leu from DDGS. A diet based on corn, soybean-meal, and 35% DDGS was f ...
