We conducted a study to understand how inositol, a naturally occurring sugar alcohol, influences anxiety levels in laying hens. Our focus was on the behavior of Lohmann LSL lite hens, which were fed two different diets—one rich and one deficient in protein—while receiving either pure inositol or high levels of phytase.
Throughout the experimental period from 19 to 59 weeks of age, we gathered data through multiple behavior assessments, which included observing their reactions to new objects and monitoring their overall health indicators like feather condition and mortality rates.
Interestingly, inositol appeared to help reduce fearfulness in these hens, which we observed through a decrease in the time it took for them to approach and peck at new objects. However, it's worth noting that while inositol also led to a drop in vent feather cover and was associated with a slight increase in mortality, its primary benefit was tied to its ability to lessen anxiety.
Phytase, on the other hand, did not yield similar effects on behavior or health. These findings point towards the potential of inositol as a useful dietary addition for improving the well-being of laying hens by reducing anxiety levels.
