Document Summary
The control diet contained 20 ppm zinc, 45ppm form either source was added in test diets, di erence (bioavailability is the same for the 2 zinc sources) are not consistent with chick date) No di erence for the pigs and no improvement with live weight: in consistent data since it worked in chicks but not pigs. Enrichment of pork loin with selenium (mg/kg fresh tissue: se-yeast is a special chelate , s in methionine and cysteine is replaced with se; se intake has been related to aspects of human health and improved pig productivity. Selenium helps improve health/ immunity: selenium rich pork = value added product. Enzymes: proteins that can be added to swine diets to assist endogenous enzymes in the breakdown of nutrients, applications: Breakdown of nutrients for which pigs dont have enzymes (eg. nsps) Breakdown of anti-nutritional factors (phytates; anti-genic proteins) Feed enzymes: break down dietary nutrients to their building blocks.
