We help pig farmers use the most effective swine feed so that they can operate profitably, sustainably and with high animal welfare standards.THE CHALLENGES FACED BY THE SWINE INDUSTRYPig producers face many challenges, including high feed costs and disease outbreaks. The three biggest pressures come from:1. Facing the sustainability challenge and the requirement to comply with regulations to redu ...

Thank you Dr. Mroz. You likely know a lot more about Trp and stress than I do. But in some of our experiments with corn protein we demonstrated a close relationship between elevated concentration of Leu in the diet and reduced serotonin in the hypothalamus. This reduction can be partly overcome by adding more Trp to the diet. Because all corn proteins including DDGS have high concentrations of Leu ...

Dear Hans, As your old professional partner from ID-DLO Lelystad (Wageningen University in The Netherlands) I am happy to know that you are still very active in the nutritional research on pigs. Your work I find very interesting and worthy to comment as follows: Optimizing Trp:Lys ratios in diets for grower pigs (without or with DDG) has been subjected to many studies across the world. From my ...

Stefano Calamanti Dr. Calamanti, thank you for this interesting comment. The important role of Trp for immune function is more commonly known via its metabolism through kynurenine pathway which is increased under immune challenge (inflammation). I think increased understanding on the complex role or pathway of Trp on improving microbiome (promotes Lactobacillus or reduce susceptibility to E. coli ...

Dear Dr. Donzele,Thank you for the feedback and additional explanation. Indeed, I fully agree on the merit of adding an additional diet (we can call it as reference or positive control diet) containing Lys at adequate level. For example, we added such positive control diet which contained both Lys and Trp at adequate level in an experiment in Germany to check/make sure Lys was suboptimal in the Tr ...

Juarez Donzele Dear Dr. Donzele,Thank you for the comment. I can explain the logic for our trial design, setting Lys as suboptimal level in all diets (also for the diet at 15% Trp:Lys ratio), as follows.The requirement of an amino acid (AA), e.g. Trp and Lys, can be estimated on the basis of grams per day. This factorial approach is used in growth model (e.g. NRC, 2021). Another approach, obviousl ...

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 ...
