Abstract

A total of twenty-four sows and their offspring were used in a 20-week study to investigate the effects of feeding GM maize on maternal and offspring health. Sows were fed diets containing GM or non-GM maize from service to the end of lactation. GM maize-fed sows were heavier on day 56 of gestation (P< 0.05). Offspring from sows fed GM maize tended to be lighter at weaning (P= 0.08). Sows fed GM maize tended to have decreased serum total protein (P= 0.08), and increased serum creatinine (P< 0.05) and γ-glutamyltransferase activity (P= 0.07) on day 28 of lactation. Serum urea tended to be decreased on day 110 of gestation in GM maize-fed sows (P= 0.10) and in offspring at birth (P= 0.08). Both platelet count (P= 0.07) and mean cell Hb concentration (MCHC; P= 0.05) were decreased on day 110 of gestation in GM maize-fed sows; however, MCHC tended to be increased in offspring at birth (P= 0.08). There was a minimal effect of feeding GM maize to sows during gestation and lactation on maternal and offspring serum biochemistry and haematology at birth and body weight at weaning.
