Soya Hulls (GM)

Soybean HullsSoya Hulls

  • Soyabean hulls are a byproduct of soybean processing for soybean oil and soybean meal, obtained by the dehulling of the beans. 

  • During processing, soybeans are rolled or cracked to break the whole bean into smaller pieces and the hulls are separated by an air stream. 

  • Hulls are usually toasted to destroy their urease activity and ground to the desirable particle size.

  • The soybean hull is high in fibre (35%) and low in protein (11 %). The protein is highly degradable, while the cell wall is low in lignin and highly digestible. Ground hulls are often sold as soya mill feed. 

  • Soya hulls are very palatable and are typically used to increase bulk in rations of fine texture.They are a good source of digestible fiber, but not so good in terms of effective fiber. Their maximum incorporation in dairy cattle rations should be 20-25% of the dry matter.

  • Soya Hulls have always been popular with some, but they have recently made a major comeback as they are being widly used instead of Sugar Beet Pellets. 

  • Soya Hulls are either sold as a meal or pelletted to facilitate handling.

  • A relatively new feed on farm with compounders having traditionally taken up all available production. 

  • The product is a useful energy inclusion in all diets for most ruminant stock, with reasonable energy levels. (ME= 10 MJ/kg DM)
