title: Effect of pelleting on vitamin A assay levels of poultry feed.
abstract: Twenty samples were collected before and after pelleting a 454-kg-lot of feed and assayed for vitamin A. Vitamin A assay levels were reduced 6.5% by pelleting at 80 C. The value reported here is one-fifth the value reported in 1958 and 30% lower than the value recently reported.
