This study was conducted to evaluate changes to in vitro ruminal fluid fermentation due to the use of corn-derived dried distillers' grains with solubles (corn DDGS) as a partial or complete replacement for crushed cereal and oilseed meals in the fermentation substrate. The control substrate consisted of mixed cereal and oilseed meals (barley, wheat, soybean and rapeseed), while the experimental substrates were the same meals with increasing portions replaced with corn DDGS. Including corn DDGS decreased the total VFA concentration (P<0.05), ammonia level (P<0.001), methane emission (P<0.05) and total gas production (P<0.001) during microbial fermentation. Using DDGS-containing substrates did not change the proportions of acetate, propionate and butyrate, but did decrease the proportions of isobutyrate and isovalerate (P<0.001). The fermentation efficiency, VFA utilization index, cell yield coefficient and pH of the ruminal fluid also remained unchanged. The partial replacement of cereal and oilseed meals with corn DDGS had no deleterious effects on ruminal fluid fermentation.

This study aimed to examine the nutritional diversity of distillers' co-products in pigs. Two distinct databases were used in this study. The first was compiled through a systematic review of previous scientific publications that have evaluated the chemical composition and nutritional availability of these ingredients for pigs.

Mycotoxins, particularly deoxynivalenol (DON), are common contaminants in feed ingredients such as corn distiller's dried grains with solubles (DDGS) and pose significant risks to poultry health. This study investigated the effects of feeding naturally DON contaminated DDGS on growth performance, body composition, immunological response, and gastrointestinal health in young pullets. A total of 360, 4-week-old Hy-Line W36 pullets were randomly assigned to diets with increasing levels of naturally DON contaminated DDGS (0, 5, 10, 15, and 20%) over 28 days, resulting in dietary DON concentrations ranging from below the limit of quantification to 15.

The yellow mealworm, Tenebrio molitor, L., can be an important component of the circular economy because of its ability to transform a variety of agricultural wastes and byproducts into valuable livestock feed. Analysis of their ability to endure toxins coupled with their potential to transfer contaminants to higher trophic levels is not complete.
