Abstract: Seaweed supplement is included in diet of mammals and poultry to enhance immune response. In one embodiment, pasture forage is treated with seaweed supplement. In another embodiment, seaweed meal is directly fed to mammals and enhanced immune responses is manifested by increased width response after intradermal injection of phytohemaglutinin. In an independently inventive embodiment, seaweed supplement is administered to pigs exposed to PRRS disease to impart resistance to said disease and improve performance. In stilt another independently inventive embodiment, seaweed supplement is administered to lactating mares prior to weaning to mitigate the stress of weaning.

Abstract: Seaweed harvested from the ocean when ground as an intact meal or exposed to alkaline hydrolsis extraction procedure resulting in a water soluble form provides a feed ingredient with mineral composition and plant growth regulating activity when included as a pasture treatment or feed ingredient for mammals and poultry, resulting in enhanced immune function, enhanced health, weight gain, and meat grade quality. Steers grazing seaweed extract treated forage continued to exhibit enhanced immune function after entering feedlot phase finishin with no seaweed extract diet supplement.

Abstract: Seaweed supplement is included in diet of mammals and poultry to enhance immune response. In one embodiment, pasture forage is treated with seaweed supplement. When cattle or lambs are grazed on seaweed supplement treated endophyte-infected forage, immune function is preserved or depressed immune function is reversed. The enhanced immune function continues to the feedlot finishing phase even though no seaweed supplement is fed in that phase. In an independently inventive embodiment, seaweed supplement is administered to pigs exposed to PRRS disease to impart resistance to said disease and improve performance. In still another independently inventive embodiment, seaweed supplement is administered to lactating mares prior to weaning to mitigate the stress of weaning.

Abstract: A method for feeding ruminants being fattened for meat production, a feed supplement and a complete feed for ruminants. In the method for feeding ruminants, the ruminants are fed sorbitol and at least one ionophore antibiotic in addition to their normal feedstuff. The feed supplement contains sorbitol and at least one ionophore antibiotic together with a carrier. The complete feed contains sorbitol and at least one ionophore antibiotic in addition to a normal feedstuff for ruminants. Feeding of sorbitol and at least one ionophore antibiotic to ruminants in addition to their normal feedstuff significantly improves feed efficiency.
