Livestock, Dairy and Poultry Feeding Research
The research in feeding of waxy maize began in the 1940s. Beginning with a research report in 1944, waxy maize seemed to have the potential to increase feed conversion efficiencies compared to dent maize. Many other feeding trials were started and generally indicated a slight to clear positive advantage for feeding waxy grain. Increases of both milk production and butterfat content for lactating dairy cattle, increase in daily weight gains in fattening lambs and when fed to finishing beef cattle.
Still the extensive (mushroomed) agro-research did not lead to any large scale use in the feed industry due to analytical research analysing the pancreatic digestibility of starches of several genotypes. Waxy starch of the genome type ae, as also the genome type du and su2, for starches with a high amylose content, show an excellent digestibility. Thus, amylopectin, waxy starches alone, cannot be correlated to good digestibility. Sandsted suggests that digestibility could lie more in the structure of starch granule, in differences in bonding of the starch molecules and in possible anomalous linkages between the molecules.

Famous quotes containing the words feeding and/or research:
“We went on, feeding the hungry, giving drink to the thirsty, clothing the soldier, binding up his wounds, harboring the stranger, visiting the sick, ministering to the prisoner, and burying the dead, until that blessed day at Appomattox Court House relieved the strain.”
—M. E. W. Sherwood (1826–1903)
“Our science has become terrible, our research dangerous, our findings deadly. We physicists have to make peace with reality. Reality is not as strong as we are. We will ruin reality.”
—Friedrich Dürrenmatt (1921–1990)
