potential in comparison to the application of the control diet, with 95.5% of their potential. In this context, a standardised phyto-molecule additive demonstrated its ability to modu- late the animal immune system. It enables the pullet to


better cope with the vaccination with effects such as reduc- tion of inflammation and improvement of antibody response. Overall it leads to better pullet flock protection and better growth performance.

Amongst the ob- jectives, attain- ing pullet body weight objec- tives are critical. It is established that higher per- forming flocks of layers have high- er 18 week body weight relative to lower per- forming ones. PHOTO: PETER ROEK
