Improving pig health management with a versatile enzyme by GFMT


Recent trials confirm that the introduction of a versatile NSP (Non-Starch Polysaccharides) enzyme in pig diets, improves performance and homogeneity of animals�from weaning to slaughter. This has a positive impact on health management by a reduction of re-allotting and increased clean downtime.

 Have You Experienced
 This In Your Elevator?
        For over 35 years, and in more than
       50 countries, Tapco has been solving the
        problem of bent & torn steel buckets.

                                          Urethane • Nylon

       T   apco nonmetallic buckets have the ability to absorb impact
           in the elevator leg and “give” or “yield” to bypass an
       obstruction. They then return to their original shape and keep
       on working for you.
       Tapco buckets weigh less than their pressed steel counterparts,
       lack sharp edges and therefore are far safer and easier to handle
       when fitting an elevator.
                   With 900,000 buckets in 93 sizes stocked throughout
                  the world, Tapco has what you want, when you need it!
                    Tapco also maintains over 15 million elevator bolts
                     in imperial and metric threads in six styles. Tapco
                      fanged elevator bolts have been specifically
      Elevator Bolt   designed to work with nonmetallic buckets.

       Replace your steel buckets with Tapco – the buckets
       with the memory.
