Poultry excess iodine

Excess iodine in poultry delays sexual maturation in males and females. In laying hens excess iodine intake progressively reduces egg yield. At 2500 mg iodine/kg - diet (approximately 100 mg iodine/kg BW/day) ovulation is... 

In this respect, the suggested maximum tolerable dietary levels of iodine for common livestock in the European Union is lOmgkg feed DM. For solipeds (horses, etc.), the highest tolerable iodine concentration has been limited to 4 mg kg feed DM. Horses are considerably less tolerant to iodine excess (5 mg kg feed DM) than cattle, sheep, and poultry (NRG 1980, Hetzel and Maberly 1986, McDowell 1992). Supplementation in the amounts stated above is dangerous for the reproductive performance. An influence on the growth of chicken embryos and brain development has also been reported (Travnicek et al. 1997).
