Different alternative pellet binders affect the durability and density of Indigofera pellet

Abstract

Indigofera is one of the many legumes that contains high protein which can be utilized as ruminant protein source. Indigofera utilization for feed industries may be limited by its volume especially during transportation. To reduce high volume of Indigofera transportation, pelleting is needed. Binder is one of the main components in producing pellet. This research aimed to analyse the effect of different binders in the durability, bulk density, density, organic matter content, dry matter content, and crude protein content of Indigofera pellet. The treatments used were LignoBond DD ® as standard binder, sago flour, cornstarch, and tapioca flour. The results showed that pellet durability and density were significantly affected by pellet binder while bulk density, organic matter, dry matter, and crude protein were not affected. The best alternative pellet binder that has the same result as LignoBond® as standard binder is tapioca flour.
