In the present work, a meta-analysis for the effects of ZON on FI and WG was not conducted due to the lack of data reported in the literature.
Available data to date are summarized in table
4. Detrimental effects of dietary ZON on growth
performance of pigs are clear. Dietary ZON (mean
3.8 mg/kg in diet) resulted in 15.8% FI reductions
and 28.8% WG reductions on average
