Effects of Sources or Formulations of Vitamin K₃ on Its Stability during Extrusion or Pelleting in Swine Feed.

ABSTRACT: Two studies were conducted to determine the stability of vitamin K₃ (VK₃) in swine diets during extrusion or pelleting. The two sources were menadione sodium bisulfite (MSB) and menadione nicotinamide bisulfite (MNB), and the three formulations were crystal micro-capsule formulation and micro-sphere formulation. The recovery of six types of VK₃ in swine diets was investigated after extrusion at 100 °C or 135 °C in Experiment 1. The recovery of six types of VK₃ was investigated when the diets were pelleted at 60 °C (low temperature; LT) or 80 °C (high temperature; HT) and the length to diameter ratios were 5.2:1 (low length to diameter ratio; LR) or 7.2:1 (high length to diameter ratio; HR) in Experiment 2. In Experiment 1, MNB recovery (72.74%) w
