In this study, direct analysis in real time high resolution mass spectrometry (DART-HRMS) was used to investigate the accurate characterisation of feed additive formulations containing coccidiostats or carotenoids. The study demonstrates the efficacy of DART-HRMS in identifying the active substances in these formulations and distinguishing between feed additives with the same active substance. The protocol for this method involves two simple steps that are extracting samples with organic solvents and measuring the extracts with DART-HRMS. The study also employs various statistical tools, including a factorial design approach, to optimise the DART-HRMS settings, and multivariate statistics, to establish classification models for feed additive formulations using nominal mass spectra. Our study demonstrates the potential of DART-HRMS in ensuring the correct identification of feed additives containing various coccidiostats or carotenoids and proposes this tool as an additional means for compliance checks with EU regulations.

To develop a direct production process for TiH powder from TiO, the reduction of TiO using Mg in molten MgCl - KCl salt under a high hydrogen chemical potential was investigated. The reduction of nano-sized TiO powder was conducted at 973 - 1073 K under an Ar or Ar and 10% H mixed gas atmosphere when the mass ratios of Mg to feed and salt to feed were 1.14 - 2.

Selenium is widely acknowledged as an indispensable trace element for humans and various animals, including poultry. The addition of selenium in appropriate doses plays a crucial role in promoting poultry growth and reproduction. Conversely, both deficiency and excessive intake of selenium can pose significant threats to poultry health and production performance.
