Conclusions
Background
Maxipullet™ contains 5 feed additives
recognized as major antioxidants &
immune modulators in bird nutrition.
Better pullet development & immunity
at transfer can influence the laying
performance (start of lay, egg mass, shell
quality and lay persistence).
Results*
The trial was well executed, the birds presented good health with low mortality
and low oxidative stress.
At123days,increasedweight(p<0.05),betterFeedconversion83-123days(p<0.05)
& better tibia strength obtained with B, C & D (p<0.10).
At 123 days, higher number of birds with higher antibody titers as log (NewCastle
disease) observed with C & D (p<0.10).
No significant difference in mortality, flock uniformity, blood oxidation stress.

• MaxiPullet™ significantly improved the weight of pullets at 123
days and feed conversion at 83-123 days with treatments
B, C & D. Tibia strength with treatments B, C & D was increased
and antibodytiters(Newcastle disease) at123 dayswere higher
with treatments C & D.
• Supplementation of MaxiPullet™ showed a positive effect for
improving the general health and immune status of the birds.
Objective
To evaluate the effect of MaxiPullet™ on
pulletperformance,immunestatus&bone
development.
