Hemp, flax and canola seed cakes are byproducts of the plant oil extraction industry that have not received much attention in terms of their potential use for human food instead of animal feed. Thus, the bioactivity profiling of these oilseed cakes is of interest. For their effect-directed analysis, planar chromatography was combined with several (bio)assays, namely 2,2-diphenyl-1-picrylhydrazy...

FEED manufacturers are often forced by circumstances to focus on short-term concerns such as: How many tons were produced this week? How many customers do I have, or how much down time did I have this week? While important, short-term problems can cause manufacturers to focus on solving problems rather than pursuing the company’s mission. Manufacturers who regularly examine their company’s miss...

Improving feed efficiency is a relevant strategy to reduce feed cost and environmental waste in livestock production. Selection experiments on residual feed intake (RFI), a measure of feed efficiency, previously indicated that low RFI was associated with lower feed intake, similar growth rate, and greater lean meat content compared with high RFI. To gain insights into the molecular mechanisms u...
