Myo-inositol (inositol) affects memory, and the incidence of depression and anxiety in read more mammals.An experiment was designed to determine if pure inositol (0.16%), or high levels of phytase (3000 FTU/kg) affect the behaviour of fully beaked Lohmann LSL lite hens fed amino acid sufficient (19% crude protein (CP)) and deficient diets (16% CP), from 19 to 59 weeks of age.

The data collected included live-scan behaviour observations and novel object (NO) tests (both at 1, 10 and 40 weeks of the trial); heterophil-to-lymphocyte (H/L) ratios (week 1 and week 40 of the trial); end of trial feather cover, and pomyslnaszycie.com comb and skin lesions; and daily mortality.Reducing CP increased sitting by 2.5%.

Inositol, but not phytase, reduced the latency to peck at the NO by 300 sec.Inositol reduced vent feather cover by 12% and tended to increase mortality by 13%.No effects on H/L ratio, and comb or skin lesions were found.

In conclusion, regardless of the source, inositol reduced vent feather cover, while it tended to increase mortality.Only pure inositol reduced fearfulness in laying hens.
