Description of Feed Inspection Service : By
means of its research and the publication of its findings the ALP
essentially promotes an economic, animal and environment friendly
production of high quality foods of animal origin. The ALP supports
Swiss agricultural policies as far as animal production is concerned
and its results are obtained for the welfare of the whole population.
The ALP is one of the 5 research stations of the Office of Agriculture.
Together with the research stations FAM and FAT it comprises the
competence centre for animal production and foods from animal origin.
The ALP is in charge of the inspection of feedstuffs and authorizes the
use of new products in animal nutrition. The aim of these activities is

The laboratory has more than 40 years of experience in studying feeds
using microscopy and possess a collection of reference samples and
books as well as equipment to save images of observed particles.
Checking feeds for particles of animal origin is part of routine work
(more than 1200 samples in 2001).
The method used is the classical sedimentation and fractionation (with
Tetrachlorethylene) followed by thorough examination of sediment and
flotate under stereomicroscope and compound microscope, using well
known mounting reagents.
