Effects of Safmannan® on immune system modulation
Shahir et al. 2013, published trial results proving how Safmannan® can help preserve antibody titers in vaccinated laying hens. Birds were placed in a farm for the rearing period from D0 to 20 weeks of age. They were all vaccinated according to the same vaccination plan, including Newcastle disease (ND) and low pathogenic avian Influenza (LPAI). From weeks 33-44, half the hens were given feed supplemented with Safmannan® at 500 g/T
As the last vaccination was done 27 weeks before the blood sample and 16 weeks before Safmannan® supplementation started, the vaccine response was completed before supplementation began. During egg production, antibody titers decreased continuously. In the trial, Safmannan® helped reduce the speed of antibody titers decrease. This can help hens, in the face of genetic evolution which makes the egg production period longer, driven by the objective of producing 500 eggs per hen at 100 weeks old.
