The
aim of this study was to evaluate some pelleting characteristics of beef cattle
concentrate with added sepiolite and potassium humate alone or combined. For this purpose, one control group (basal concentrate) with no
additive and five treatment groups with 1% sepiolite (S),
0.25% potassium humate (H-25), 0.50% potassium humate (H-50), 1% sepiolite +
0.25% potassium humate (SH-25) and 1% sepiolite + 0.50% potassium humate
(SH-50) added as top-dressed
into mixer were used. For each experimental group, a total of 36 tons
of pellet concentrates were produced in six batches with 6 tons per batch. The basal pelleted
concentrate included 90.29% dry matter, 14.51% crude protein, 11.76% crude fibre and
3.14% ether extract. Results showed that adding sepiolite up to 1% in beef cattle
concentrate as top-dressed in mixer reduced moisture losses and improved the durability
of pelleted feed. Sepiolite addition
also lowered pellet water activity during storage. Adding potassium humate
alone up to 0.50% was not enough to improve the pellet quality in terms of
durability or water activity. Potassium humate supplementation alone or with
sepiolite presented with lower moisture losses than control, and it was more
evident during storage. In conclusion, the use of sepiolite in beef cattle
concentrates as pellet binder seemed to be providing more durable feed pellets
with lower water activity. Promising results were obtained from both the
supplements in limiting the moisture losses post- pelleting and storage. Regarding
the role of potassium humate as pellet binder in animal feed industry further
research is needed.
