(1) Rubber juice secreted by trees: dragon gum, guara gum, pectin, etc. These binders are susceptible to pH, humidity, mineral salts, etc. and reduce viscosity, so they are not widely used.

(2) Rare earth, clay type binder: bentonite, clay, sodium clay, attapulg, etc. These clay minerals have a lower viscosity and a correspondingly increased proportion. However, it is said that the 202 feed binder developed by Beijing Shenda Mineral Feed Research Institute is not only suitable for steam granulation, but also for cold pressing granulation.

(3) Plant starch: wheat, corn, cassava, potato and other starch or modified starch. The size of the adhesion of these binders depends on the type of starch and feed processing equipment and operating technology.

(4) Seaweed gum: sodium alginate, kelp gum, agar, etc. Seaweed binders generally have strong adhesion, but they are expensive and are generally used in experimental research feeds.
