Effect of withholding macromolecules on the duration of intestinal permeability to colostral IgG in foals.

Published: 2006-02-20

Brief content of the abstract
The objective of these authors was to quantify absorption of colostral IgG by healthy neonatal foals and to test the hypothesis that delayed ingestion of macromolecules prolongs the duration of intestinal permeability to immunoglobulins (Ig) in 13 newborn foals. The foals were were fed either a glucose-electrolyte solution or a commercial milk replacer for 12 h after birth, before being fed a known amount of colostral IgG. A control group was fed a known amount of colostral IgG from birth. The authors concluded on the basis of their results that colostrum should be supplied to foals within 12 h of birth for best uptake of IgG. The type of fluid administered to foals before the ingestion of colostrum did not influence subsequent absorption of Ig. A full abstract can be found on Pubmed.
