Forum: Sucrose or molasses as a replacement for Lactose in Pig Diets
Published:April 16, 2011
By:Joaquin Armando Paulino
Mavromichalis et al, 2001, showed that piglets use sucrose as efficiently as lactose, this had been shown by other studies (Jin et al, 1998 and Lee et al 2000). Molasses is a byproduct of the extraction of sucrose from cane or beets, with about 75% dry matter and 50% of sugars. In molasses, sucrose is in equilibrium with glucose and fructose. Molasses is rich in potassium, so one must pay attention to the dietary electrolyte balance to prevent diarrhea.
Mr Paulino,
Previous production experience has shown an increase in e-coli scours when sucrose is used. This was observed over 30 years ago. Any thoughts on this?

Mr. Dan
less than 50% of E. Enteric coli using sucrose as carbon source, capture and phosphorylate sucrose PTS via a specific system, which generates sucrose-6-phosphate intracellular subsequently is hydrolyzed by a sucrose-6-phosphate hidrolaza D-glucose-6-phosphate and D-fructose. the strain of E. Coli EC3132 and O157: H7 are more able to use sucrose
