Presence of Unabsorbed Free Amino Acids at the End of the Small Intestine of Humans and Pigs: Potential Implications for...
Milieurisico bestrijdingsmiddelen en veterinaire stoffen in mest via effecten op de voedselketen voor weidevogels
In 2019, a report was issued by Buijs en Samwel-Mantingh which claimed a possible relation between the occurrence of pesticides and veterinary drugs in manure and the decline of farmland birds, which feed on (soil) invertebrates allegedly impacted by these substances. The current research project provides an in-depth analysis of the reliability of ...
309 ASAS-EAAP Talk: Modelling digestion kinetics: the next step in the evaluation of feed ingredients
There is increasing importance of upcycling of low-opportunity-cost feed, food waste, and food processing byproducts into animal products, strongly increasing the variation in the nutritional quality of feed ingredients. Traditionally, feed ingredients are evaluated based on their measured extent of digestion. Increasing awareness that not only the...

A study of the structure-activity relationship of oligomeric ellagitannins on ruminal fermentation in vitro
The aim of this study was to investigate how the degree of oligomerization of ellagitannins (ET) influences their ability to alter ruminal fermentation. Dimeric to heptameric ET were isolated from rosebay willowherb (Epilobium angustifolium) flowers and purified. Ellagitannins were tested in vitro on a mixture of grass silage and buffered rumen flu...
β-Glucans and Resistant Starch Alter the Fermentation of Recalcitrant Fibers in Growing Pigs
Interactions among dietary ingredients are often assumed non-existent when evaluating the nutritive value and health effects of dietary fiber. Specific fibers can distinctly affect digestive processes; therefore, digestibility and fermentability of the complete diet may depend on fiber types present. This study aimed to evaluate the effects of read...

Effect of cavacrol on fermentation characteristics in the ileum of piglets during the process of weaning
Twelve landrace piglets selected from four different sows were fitted with an ileal T-shaped cannula at an age of 17 to 18 days (d-10; BW 6.13 ± 0.46 kg). After surgery, the animals were placed back with the sows. Ten days later (d0) the animals were weaned, placed on metabolic cages and assigned to one of the two dietary treatments, a control diet...
